Foreign Income and Gains Form SA106


Understanding the SA106 Form – What It Is and Why It Matters

Hey there, UK taxpayers and business owners! If you’ve ever scratched your head wondering what the SA106 form is all about, you’re in the right place. Whether you’re sipping tea in London or managing a holiday rental in Spain, this form could be your ticket to sorting out your foreign income with HM Revenue & Customs (HMRC). Let’s break it down in plain English, sprinkle in some stats, and get you clued up on why this little document deserves your attention.


What Exactly Is the SA106 Form?

The SA106 form is an optional but oh-so-important part of the UK Self-Assessment tax return. It’s designed for folks who’ve earned money from outside the UK—think foreign dividends, overseas pensions, or rental income from that villa in Portugal. Officially titled the “Foreign” pages, it’s where you spill the beans on your international earnings for the tax year, which runs from 6 April to 5 April the following year. For instance, the latest form covers 6 April 2023 to 5 April 2024.


Why bother? Well, HMRC wants to make sure you’re paying the right amount of tax on every penny you’ve earned globally. Plus, it’s your chance to claim Foreign Tax Credit Relief (FTCR) if you’ve already paid tax abroad—more on that juicy bit later. Without the SA106, you might end up paying tax twice or missing out on relief you’re entitled to. No one wants that, right?


Who Needs to File the SA106?

Not everyone needs to wrestle with this form. It’s aimed at UK residents with foreign income or gains, or non-residents with UK tax obligations tied to overseas earnings. HMRC’s latest data shows over 1.2 million UK taxpayers reported foreign income in the 2022-23 tax year, a number that’s been creeping up by about 3% annually, thanks to globalization and remote work. If you’re in this boat, the SA106 is your mate.


Here’s a quick rundown of who’s likely to need it:

  • Expats living in the UK with overseas bank interest or dividends.

  • Landlords renting out properties abroad—like Sarah from Manchester, who rents a flat in Dubai.

  • Pensioners receiving social security or pensions from another country.

  • Investors with shares in foreign companies paying dividends.


In 2023, HMRC processed over 10.5 million Self-Assessment returns, and roughly 11% included the SA106, according to their stats. That’s a hefty chunk of folks dealing with international income!


What Kind of Income Goes on the SA106?

The form covers a smorgasbord of foreign earnings. Here’s the lowdown based on the latest SA106 (2024 version):


  • Overseas savings interest: Think interest from a bank account in Germany.

  • Foreign dividends: Cash from shares in a US tech firm.

  • Remitted income: Money you’ve brought back to the UK from abroad.

  • Overseas pensions: Payments from a French retirement scheme.

  • Property income: Rent from that Italian farmhouse you inherited.

  • Other gains: Like profits from selling an offshore fund.


Fun fact: In 2022-23, foreign dividends alone accounted for £4.8 billion in reported income, per HMRC’s annual report. That’s a lot of dosh crossing borders!


Why It’s a Big Deal: Double Taxation and FTCR

Here’s where it gets interesting. If you’ve paid tax on your foreign income in another country, the UK might still want a slice of the pie—unless you claim FTCR. The SA106 lets you offset foreign tax against your UK tax bill, avoiding the nightmare of double taxation. The UK has double taxation treaties with over 130 countries (as of the latest count on GOV.UK), so check if your income’s country is on the list.


For example, Tom, a freelance designer from Bristol, earned £20,000 from a German client in 2023. He paid £5,000 in German tax. Without FTCR, he’d owe UK tax on the full £20,000—say, £4,000 at the basic rate of 20%. With FTCR, he offsets the £5,000, reducing his UK tax to zero and saving a cool £4,000. Sweet deal, huh?


Some Eye-Opening Stats

Let’s throw in some numbers to give you the big picture:


  • £12.7 billion: Total foreign income reported to HMRC in 2022-23.

  • 37%: Percentage of SA106 filers claiming FTCR, per HMRC’s latest figures.

  • £1.9 billion: Relief granted through FTCR in the same year.

  • 45,000: Number of UK taxpayers reporting overseas property income in 2023.


These figures show the SA106 isn’t just a niche form—it’s a lifeline for thousands navigating the tax maze.


A Real-Life Case Study: Meet Priya

Priya, a 35-year-old marketing consultant from Leeds, moved back to the UK in 2023 after working in Singapore. She earned £15,000 in interest from a Singaporean savings account and £10,000 in dividends from a local firm. Singapore taxed her £3,750 total. Back in the UK, she filed her Self-Assessment with the SA106, reporting both income streams. Thanks to the UK-Singapore tax treaty, she claimed FTCR, slashing her UK tax liability from £5,000 to £1,250. Without the SA106, she’d have been out of pocket—big time.


How Does It Fit Into Your Tax Return?

The SA106 isn’t a standalone form—you attach it to your main SA100 Self-Assessment return. It’s got six pages (F 1 to F 6), each tackling different bits of foreign income or relief claims. You’ll need your Unique Taxpayer Reference (UTR)—a 10-digit code HMRC gives you—to file it. Over 12 million UTRs are active in the UK as of 2023, so you’re in good company.


Submitting it’s a breeze—do it online via HMRC’s portal or go old-school with a paper return. The deadline? 31 January following the tax year (e.g., 31 January 2025 for 2023-24), if filed online. Miss it, and you’re looking at a £100 penalty, rising to £10/day after three months. Ouch!



What You Can Report on the SA106 Form – Digging Into the Details

Alright, folks, now that you’ve got the basics of the SA106 form under your belt, let’s get into the meaty stuff—what exactly can you slap onto those six pages? Whether you’re a jet-setting entrepreneur or just someone with a sneaky overseas savings account, this part’s all about unpacking the types of income and reliefs you can report, with some real-world twists to keep it relatable. Plus, I’ll throw in some pro tips to dodge the traps that trip up even the savviest taxpayers.


The Anatomy of the SA106: Six Pages, Endless Possibilities

The SA106 isn’t just a single sheet—it’s a six-page beast, each section tailored to a specific slice of your foreign financial life. Here’s the rundown, straight from the latest 2024 version on GOV.UK:


  • Page F 1: Unremittable income and Foreign Tax Credit Relief (FTCR) claims.

  • Pages F 2 & F 3: Foreign savings, dividends, pensions, and income received abroad.

  • Pages F 4 & F 5: Income from overseas properties.

  • Page F 6: FTCR on other income, plus gains from offshore funds or life insurance policies.


Each page has boxes and columns to fill in, and trust me, they’re not as scary as they look once you know what’s what. Let’s break it down with some examples.


Unremittable Income – When Cash Gets Stuck

Ever had money stuck overseas because of currency restrictions or banking woes? That’s “unremittable income,” and Page F 1 (Box 1) is where you flag it. Put an ‘X’ in the box if you couldn’t bring it to the UK, then spill the details in the “Any other information” section of your main tax return.


Take Liam, a graphic designer from Edinburgh. In 2023, he earned £8,000 freelancing for a client in Argentina. Due to strict currency controls, he couldn’t transfer it to his UK account. He marked Box 1 with an ‘X’ and explained the situation—HMRC didn’t tax him on it since it never hit British soil. Handy, right? HMRC data shows about 2,500 taxpayers claimed unremittable income in 2022-23, a small but growing group.


Foreign Savings and Dividends – Pages F 2 & F 3

Pages F 2 and F 3 are your go-to for income like interest, dividends, pensions, and anything remitted to the UK. You’ll need to list:


  • Country code: A two-letter code (e.g., “US” for USA—check the Foreign Notes).

  • Amount before tax: What you earned in pounds.

  • Foreign tax paid: What you’ve already shelled out abroad.


For instance, Emma, a nurse from Cardiff, earned £2,000 in interest from a Spanish savings account in 2023. Spain took £400 in tax. She listed “ES” in Column A, £2,000 in Column B, and £400 in Column C on Page F 2. Then, on Page F 3, she ticked Column E to claim FTCR, reducing her UK tax hit. Simple, yet effective.


Stats-wise, overseas savings interest hit £2.1 billion in 2022-23, while foreign dividends topped £4.8 billion, per HMRC. That’s a lot of cash flowing into these pages!


Overseas Property Income – Pages F 4 & F 5

Got a holiday home abroad? Pages F 4 and F 5 are your playground. You’ll report rental income, expenses, and any capital allowances here. Note: If it’s furnished holiday accommodation in the European Economic Area (EEA), use the UK Property pages (SA105) instead—HMRC’s quirky rule.


Consider Raj, a Birmingham shop owner with a rental flat in Cyprus. In 2023, he earned £12,000 in rent, spent £3,000 on repairs, and claimed £500 in capital allowances for a new boiler. On Page F 4, he listed the income and expenses, netting a taxable profit of £8,500. HMRC says over 45,000 UK taxpayers reported foreign property income last year, up 5% from 2021-22.


Other Income and Gains – Page F 6

Page F 6 is the catch-all for stuff like employment income taxed abroad, gains from offshore funds, or foreign life insurance payouts. You’ll need the country code, foreign tax paid, and taxable amount. Plus, it’s where you claim FTCR on income reported elsewhere in your return.


Sophie, a London-based consultant, sold an offshore fund in 2023 for a £10,000 gain, paying £2,000 in French tax. She reported it on Page F 6, claimed FTCR, and cut her UK tax by £2,000. HMRC data pegs offshore fund gains at £1.3 billion in 2022-23—serious money!


Foreign Tax Credit Relief – The Double Taxation Buster

FTCR is the star of the SA106 show. If you’ve paid tax abroad, you can offset it against your UK tax bill, up to the UK tax due on that income. Box 2 on Page F 1 is for the total FTCR if you’re calculating your tax yourself. Otherwise, HMRC does the math.

Here’s a table to show how it works, using hypothetical 2023 figures:

Income Type

Amount (£)

Foreign Tax (£)

UK Tax Before FTCR (£)

FTCR Claimed (£)

UK Tax After FTCR (£)

German Dividends

5,000

1,000

1,000 (20%)

1,000

0

Italian Rent

10,000

2,500

2,000 (20%)

2,000

0

In 2022-23, FTCR saved taxpayers £1.9 billion, with 37% of SA106 filers claiming it. That’s a lifeline worth grabbing!


Common Pitfalls to Avoid

Filling out the SA106 isn’t rocket science, but it’s easy to trip up. Here are some gotchas to watch for:


  • Currency Conversion: All figures must be in UK pounds. Use the HMRC exchange rates (updated monthly on GOV.UK) for accuracy.

  • Double-Checking Treaties: Not all foreign tax qualifies for FTCR—check the UK’s double taxation agreements.

  • Missing Deadlines: File by 31 October for paper returns or 31 January for online. Late filings cost £100, with £1.2 million in penalties issued in 2023.

  • Forgetting Remittance: If you bring foreign income to the UK, it’s taxable unless exempt—don’t skip this step.


Case Study: Jack’s Dividend Drama

Jack, a Sheffield retiree, received £6,000 in US dividends in 2023, with £900 withheld as US tax. He forgot to convert the amount to pounds (£4,800 at the exchange rate) and didn’t claim FTCR initially. After a nudge from his accountant, he resubmitted his SA106, claimed £900 relief, and saved £960 in UK tax. Lesson? Details matter!


Tools to Make It Easier

HMRC’s got your back with resources like the “Foreign Notes” and Helpsheet 263 for FTCR calculations—grab them at GOV.UK. Online filing also auto-checks some errors, used by 9.8 million taxpayers in 2023. Sweet, huh?



How to Fill Out SA106 Form – Step-by-Step Guide for Pages F 1 to F 3

Alright, you lovely lot, it’s time to roll up our sleeves and tackle the SA106 form head-on! In this part, we’re diving into Pages F 1 to F 3—think unremittable income, Foreign Tax Credit Relief (FTCR), and all that juicy foreign savings and dividend stuff. I’ll walk you through each question with sample answers, using relatable examples like your mate next door. No jargon overload here—just clear, practical steps to get it done. Let’s crack on!


Page F 1: Unremittable Income and FTCR Basics

Page F 1 kicks things off with two key bits: unremittable income and your total FTCR if you’re doing the tax math yourself. Here’s how to handle it.


Question 1: Unremittable Income

  • What It Asks: “If you were unable to transfer any of your overseas income to the UK, put ‘X’ in the box – and give details in the ‘Any other information’ box on your tax return or on a separate sheet.”

  • What It Means: If cash got stuck abroad due to restrictions (like currency controls), you flag it here. HMRC won’t tax it if it’s genuinely unremittable.

  • Sample Answer: Let’s say Aisha, a Liverpool-based translator, earned £5,000 from a client in Venezuela in 2023. Currency laws blocked her from transferring it. She puts an ‘X’ in Box 1 and writes in the “Any other information” section (Page TR 7 of the SA100): “£5,000 earned in Venezuela, unremittable due to exchange controls—bank statements available.” Done!

  • Tip: Keep proof (e.g., bank letters) handy—HMRC might ask. Only about 2,500 taxpayers claimed this in 2022-23, so it’s niche but legit.


Question 2: Total Foreign Tax Credit Relief

  • What It Asks: “If you’re calculating your tax, enter the total Foreign Tax Credit Relief on your income.”

  • What It Means: If you’re working out your own tax bill (not letting HMRC do it), tally up all the FTCR you’re claiming here. Use Helpsheet 263’s Working Sheet if needed.

  • Sample Answer: Meet Ollie, a Bristol teacher with £3,000 in German dividends (taxed £600 abroad) and £2,000 in Spanish interest (taxed £400). His total FTCR is £1,000 (capped at his UK tax of £1,000 on £5,000 at 20%). He enters “1000” in Box 2. Easy peasy.

  • Tip: FTCR can’t exceed your UK tax liability on that income—£1.9 billion was claimed in 2022-23, so it’s a biggie!


Pages F 2 & F 3: Income from Overseas Sources

These pages are where you list foreign savings, dividends, pensions, and more. Page F 2 has Columns A-C for the basics, while F 3 adds Columns D-F for extra details and FTCR claims. You’ll need the “Foreign Notes” for country codes—grab them at GOV.UK. All amounts are in UK pounds, so convert using HMRC’s exchange rates.


Interest and Other Income from Overseas Savings

  • Columns A-C (Page F 2):

    • A: Country or territory code: Where the income’s from.

    • B: Amount before tax: Gross amount in £.

    • C: Foreign tax taken off: Tax paid abroad in £.

  • Sample Answer: Tara, a Glasgow nurse, earned £1,500 interest from a French account, taxed £300 in France. She writes:

    • A: “FR”

    • B: “1500”

    • C: “300”

  • Columns D-F (Page F 3):

    • D: Special Withholding Tax/UK tax: Usually blank unless specific taxes apply.

    • E: Claim FTCR: Put ‘X’ if claiming relief.

    • F: Taxable amount: Amount taxable in the UK (often same as B).

  • Sample Answer: Tara leaves D blank (no special tax), puts ‘X’ in E (claiming FTCR), and writes “1500” in F. Her £300 FTCR cuts her UK tax from £300 to zero. Nice one!


Dividends from Foreign Companies

  • Columns A-C (Page F 2):

  • Sample Answer: Greg, a Hull mechanic, got £4,000 in US dividends, taxed £600. He enters:

    • A: “US”

    • B: “4000”

    • C: “600”

  • Columns D-F (Page F 3):

  • Sample Answer: No special tax (D blank), ‘X’ in E, and “4000” in F. His £600 FTCR wipes out his £800 UK tax liability (capped at £600).


Remitted Foreign Savings Income

  • Sample Answer: Nia, a Cardiff artist, brought £2,000 of Spanish savings interest to the UK, taxed £400 there. She lists:

    • A: “ES”

    • B: “2000”

    • C: “400”

    • D: Blank, E: ‘X’, F: “2000”

  • Note: “Remitted” means brought to the UK—crucial for taxability.


Remitted Foreign Dividend Income

  • Sample Answer: Same deal for dividends. If Greg remitted his £4,000 US dividends, he’d repeat the above, adjusting for remittance rules.


Overseas Pensions, Social Security Benefits, and Royalties

  • Sample Answer: Elsie, a retired Exeter librarian, gets a £6,000 Canadian pension, taxed £1,200. She enters:

    • A: “CA”

    • B: “6000”

    • C: “1200”

    • D: Blank, E: ‘X’, F: “6000”

  • Tip: Check double taxation treaties—Canada-UK treaty caps relief here.


Dividend Income Received by a Person Abroad

  • Sample Answer: If Elsie’s pension included £1,000 dividends paid to a Canadian trust, she’d list it separately with Helpsheet 262 guidance.

All Other Income Received by a Person Abroad
  • Sample Answer: If Nia earned £3,000 freelancing for a Dutch firm, paid to a Dutch account, she’d list:

    • A: “NL”

    • B: “3000”

    • C: “600”

    • D: Blank, E: ‘X’, F: “3000”


Totals (Page F 3, Boxes 3-8)

  • What It Asks: Sum up each category’s Column B amounts in Boxes 3-8.

  • Sample Answer: Tara’s total interest (Box 3) is “1500”; Greg’s dividends (Box 5) are “4000”. Add up all rows if you’ve got multiple entries.


Real-Life Example: Filling It Out

Let’s tie it together with Priya from Leeds (from Part 1). She’s got £15,000 Singapore interest (£3,000 tax) and £10,000 dividends (£750 tax) in 2023:


  • Page F 1: Box 1 blank (all remittable), Box 2 “3750” (total FTCR).

  • Page F 2:

    • Interest: A: “SG”, B: “15000”, C: “3000”

    • Dividends: A: “SG”, B: “10000”, C: “750”

  • Page F 3:

    • Interest: D: Blank, E: ‘X’, F: “15000”

    • Dividends: D: Blank, E: ‘X’, F: “10000”

    • Box 3: “15000”, Box 5: “10000”


Her £3,750 FTCR slashes her UK tax from £5,000 to £1,250—boom!


Quick Tips for Pages F 1-3

  • Double-Check Codes: Wrong codes mess up FTCR claims.

  • Keep Records: Bank statements or tax slips prove your figures.

  • Convert Correctly: £2.1 billion in savings interest was reported in 2022-23—accuracy matters!


Pages F 4 & F 5: Income from Land and Property Abroad

These pages are all about foreign property income—rents, expenses, and allowances. If your property’s a furnished holiday let in the European Economic Area (EEA), skip this and use SA105 instead. Otherwise, grab your calculator and let’s go!


Boxes 14-24.2: Property Income Details

  • What It Asks: Report income, expenses, and allowances for each property, then summarize totals.

  • What It Means: You’ll list every foreign property separately if you’ve got multiple, but sum it all up in one set of boxes.


Box 14: Total Income
  • Sample Answer: Jamal, a Luton barber, rents a Spanish flat for £10,000 in 2023. He enters “10000” in Box 14.

  • Tip: Convert to £ using HMRC exchange rates—£10.2 billion in foreign property income was reported in 2022-23!


Box 14.1: Property Income Allowance
  • What It Asks: Claim £1,000 allowance instead of expenses (optional).

  • Sample Answer: Jamal skips this (his expenses exceed £1,000), leaving it blank.


Box 15-20: Expenses
  • Examples:

    • Box 16 (Repairs): Jamal spent £2,000 fixing a leak—“2000”.

    • Box 18 (Other): £1,000 on agent fees—“1000”.

    • Others blank if no costs apply.

  • Tip: Over 45,000 taxpayers reported property income in 2023—expenses cut your tax bill!


Box 21-23: Capital Allowances
  • Box 21 (Equipment): Jamal bought a £500 fridge—“500”. (Not for residential lettings, though—check rules.)

  • Box 21.1-22.2: Blank unless you’ve got zero-emission vehicles or building allowances.

  • Box 23 (Domestic Items): £300 for a new sofa—“300”.


Box 24: Adjusted Profit/Loss
  • Sample Answer: Income (£10,000) minus expenses (£3,000) and allowances (£800) = “6200” in Box 24.

  • Formula: Box 18-20 minus Box 21-23, unless claiming allowance.


Box 24.1-24.2: Residential Finance Costs
  • Sample Answer: Jamal’s mortgage interest is £1,500—“1500” in 24.1. No carry-forward, so 24.2 is blank.

  • Note: This gets a tax credit, not a deduction—tricky but key!


Real-Life Example

Jamal’s flat:

  • Box 14: “10000”

  • Box 16: “2000”

  • Box 18: “1000”

  • Box 21: “500”

  • Box 23: “300”

  • Box 24: “6200”

  • Box 24.1: “1500” His taxable profit’s £6,200, with a credit for £1,500 interest—sorted!


Page F 6: Foreign Tax Paid and Other Gains

Page F 6 wraps up with foreign tax on employment or other income, plus gains from offshore funds or life insurance. It’s also where you claim FTCR for income reported elsewhere in your return.


Foreign Tax Paid on Employment, Self-Employment, and Other Income

  • Columns A-F:

    • A: Country code: Where tax was paid.

    • C: Foreign tax paid: Amount in £.

    • E: Claim FTCR: ‘X’ if claiming.

    • F: Taxable amount: UK-taxable portion.

  • Sample Answer: Leila, a Manchester freelancer, earned £15,000 in Germany, taxed £3,000. She lists:

    • A: “DE”

    • C: “3000”

    • E: ‘X’

    • F: “15000”

  • Tip: Note where this income appears (e.g., SA102 for employment) in “Any other information.” HMRC processed £1.3 billion in such income in 2022-23.


Gains from Offshore Funds

  • Sample Answer: Kieran, a Norwich IT guy, sold a Luxembourg fund for a £8,000 gain, taxed £1,600. He enters:

    • A: “LU”

    • C: “1600”

    • E: ‘X’

    • F: “8000”

  • Note: Use Helpsheet 261 for complex gains—offshore funds hit £1.3 billion in 2022-23.


Gains on Foreign Life Insurance Policies

  • Sample Answer: If Leila cashed a £5,000 Italian policy, taxed £1,000:

    • A: “IT”

    • C: “1000”

    • E: ‘X’

    • F: “5000”

  • Tip: Rare but growing—check policy docs.


Case Study: Raj’s Property and Fund Combo

Raj from Part 2 has a Cyprus flat and sold a Greek fund:

  • Page F 4:

    • Box 14: “12000”

    • Box 16: “3000”

    • Box 21: “500”

    • Box 24: “8500”

  • Page F 6:

    • Fund gain: A: “GR”, C: “2000”, E: ‘X’, F: “10000” His FTCR (£2,000) offsets his UK tax on the £10,000 gain—sweet relief!

Practical Pointers for Pages F 4-6

  • Property Records: Keep receipts—HMRC loves proof.

  • Treaty Check: Ensure foreign tax qualifies for FTCR (130+ treaties exist).

  • Multiple Properties: Attach extra sheets if needed—label clearly.


Why This Matters

Filling Pages F 4 to F 6 right can save you thousands. In 2022-23, 37% of SA106 filers claimed FTCR, totaling £1.9 billion in relief. Mess it up, and you’re overpaying or facing penalties—£1.2 million in fines were dished out last year for late or wrong returns.

Submitting the SA106 Form – Deadlines, Mistakes, and Pro Tips

Hello again, you brilliant UK taxpayers and business owners! We’ve conquered the SA106 form page by page, and now it’s time to tie it all together—how to submit it, dodge the pitfalls, and make the process smoother than a cuppa on a rainy day. Whether you’re a newbie or a seasoned filer, this part’s got the latest deadlines, real-life lessons, and handy tricks to keep HMRC happy. Let’s finish strong!


How and When to Submit the SA106

The SA106 isn’t a solo act—it tags along with your main SA100 Self-Assessment return. You’ve got two ways to send it off:


  • Online: Via HMRC’s portal at GOV.UK. It’s quick, and 9.8 million taxpayers filed online in 2023—way more than paper!

  • Paper: Print the SA106 from GOV.UK, fill it out, and post it with your SA100. Old-school but still valid.


Deadlines are non-negotiable:

  • Paper Filing: 31 October after the tax year (e.g., 31 October 2024 for 2023-24).

  • Online Filing: 31 January following the tax year (e.g., 31 January 2025 for 2023-24).


Miss the boat? HMRC slaps a £100 penalty, rising to £10/day after three months, up to £1,000 max. In 2023, late filers coughed up £1.2 million in fines—don’t be one of them! You’ll need your Unique Taxpayer Reference (UTR)—over 12 million are active in the UK—so have it ready.


Common Mistakes to Avoid

Even the sharpest folks stumble with the SA106. Here’s what to watch out for, with some real-world oopsies to learn from:


  • Wrong Currency: Everything must be in UK pounds. HMRC’s exchange rates (updated monthly on GOV.UK) are your best mate. Example: Fiona from Glasgow reported €5,000 Irish interest as euros, not £4,200. She had to amend it—hassle city!

  • Missing FTCR: Forgetting to tick Column E or Box 2 for Foreign Tax Credit Relief (FTCR) is a classic. In 2022-23, 37% of filers claimed £1.9 billion in FTCR—don’t leave cash on the table!

  • Incomplete Details: Skipping country codes or proof for unremittable income can trigger HMRC queries. Liam from Part 2 dodged this by attaching bank letters—smart move.

Case Study: Chloe’s Late-Filing Lesson

Chloe, a Brighton yoga instructor, earned £7,000 from a French retreat in 2023, taxed £1,400 abroad. She filed her SA106 online on 2 February 2025—two days late. She nailed the FTCR claim, saving £1,400, but copped a £100 penalty. “I thought online meant anytime in January,” she groaned. Lesson? Mark 31 January in bold!


Top Tips to Nail the SA106

Here’s how to make this as painless as possible:


  • Go Digital: Online filing auto-flags errors and gives you till January. Over 85% of Self-Assessment returns were digital in 2023—join the club!

  • Use HMRC Tools: The “Foreign Notes” and Helpsheets (e.g., 263 for FTCR) at GOV.UK are gold. They’ve got country codes, worksheets, and more.

  • Keep Records: Bank statements, tax slips, and expense receipts are your shield if HMRC knocks. In 2022-23, 10% of SA106 filers faced queries—proof saves the day.

  • Check Treaties: The UK’s 130+ double taxation agreements (listed on GOV.UK) cap relief. For example, the UK-US treaty limits dividend FTCR to 15%—know your deal!

  • Start Early: Beat the rush—over 3 million taxpayers filed in the last week of January 2023, risking errors.

How Can A Tax Accountant Help You With Reporting Foreign Income and Gains in Self-Assessment Tax Return?

When it comes to dealing with tax complexities, a professional tax accountant can be invaluable, especially in the context of reporting foreign income and gains in a self-assessment tax return. As globalisation increases and more people generate income or own assets across international borders, understanding the tax implications becomes crucial.


Why Foreign Income Matters

Foreign income refers to income earned outside of your home country. This can come from various sources like employment, a business, or rental properties overseas. If you are a resident of a country that operates on a worldwide income tax system, you are obligated to report and pay taxes on your global income.


Likewise, foreign gains pertain to capital gains made from selling overseas assets such as shares, property, or other investments. The tax rules and rates applied to these gains vary based on the specifics of your situation and the rules of your country of residence.


The Complexity of International Tax Laws

Tax laws vary dramatically from one country to another. Each jurisdiction may have different laws about what constitutes taxable income, tax rates, deductions, exemptions, and how foreign income and gains are handled. These variations create a complex maze of regulations that can be challenging for individuals to navigate without professional help.


The Role of a Tax Accountant

Tax accountants specialise in understanding and applying tax laws. They can assist with preparing and filing tax returns, providing advice on tax planning strategies, and resolving tax-related issues. In the context of foreign income and gains, their expertise becomes even more critical. Here are a few ways a tax accountant can assist:


Accurate Reporting

Tax accountants have the knowledge and experience to ensure that all foreign income and gains are correctly reported on your tax return. They can determine what needs to be declared, calculate the correct amounts, and complete the necessary paperwork. This can help you avoid errors that could lead to penalties or audits.


Double Taxation Avoidance

One of the challenges of dealing with foreign income and gains is the risk of double taxation. This occurs when the same income is taxed in two different countries. Most countries have treaties or domestic laws to prevent this, but understanding and applying these rules can be complicated. Tax accountants can guide you on how to claim relief under these treaties or laws to avoid or mitigate double taxation.


Compliance with Tax Laws

Tax laws change frequently, and staying updated is a taxing task in itself. A professional tax accountant can help you remain compliant with these changes, especially those related to foreign income and gains. They can provide advice on new regulations, how they affect you, and what steps you should take in response.


Tax Planning Strategies

Tax accountants can also help with tax planning strategies to minimise your overall tax liability. For instance, they can advise on timing the sale of foreign assets to reduce capital gains tax or using foreign tax credits effectively. This proactive approach to managing your taxes can lead to significant savings over time.


Navigating the complexities of reporting foreign income and gains in a self-assessment tax return can be challenging. However, a tax accountant can provide invaluable assistance in ensuring accurate reporting, avoiding double taxation, keeping up with changing tax laws and devising effective tax planning strategies. The peace of mind that comes with knowing your international tax affairs are in order is, in itself, a valuable benefit.

20 Most Important FAQs about A106 Form


Q1. Can you file the SA106 form separately from the SA100 Self-Assessment return?

A. No, the SA106 must be submitted as part of your main SA100 Self-Assessment tax return, either online or on paper, as it’s an additional set of pages, not a standalone document.


Q2. What happens if you don’t report all your foreign income on the SA106?

A. If you fail to report all foreign income, HMRC can impose penalties up to 100% of the unpaid tax, plus interest, and in serious cases, pursue criminal prosecution for tax evasion.


Q3. Do you need to file the SA106 if you’re a UK resident but all your foreign income is tax-free under a treaty?

A. Yes, you should still file the SA106 to declare the income and claim the treaty exemption, ensuring HMRC recognizes it’s not taxable in the UK.


Q4. Can you claim Foreign Tax Credit Relief if the foreign tax was paid in a previous tax year?

A. No, FTCR can only be claimed for foreign tax paid in the same tax year as the income it relates to, per HMRC rules as of 2025.


Q5. How do you know if your foreign income qualifies for a double taxation treaty?

A. You can check the specific double taxation treaty on GOV.UK under “Tax Treaties” to see if your income type and country are covered, as each treaty has unique terms.


Q6. What’s the difference between the SA106 and the SA109 for non-residents?

A. The SA106 is for UK residents with foreign income, while the SA109 is for non-residents with UK income, addressing different tax obligations.


Q7. Can you amend your SA106 after submitting it if you forgot some foreign income?

A. Yes, you can amend your tax return within 12 months of the online filing deadline (e.g., by 31 January 2026 for 2023-24) via HMRC’s online portal or by post.


Q8. Do you need to file the SA106 if you’re a UK citizen living abroad permanently?

A. No, if you’re non-resident for UK tax purposes (per the Statutory Residence Test), you typically don’t file the SA106 unless you have UK-taxable foreign income.


Q9. How does HMRC verify the foreign tax you’ve paid for FTCR?

A. HMRC may request foreign tax certificates, receipts, or official statements from the overseas tax authority to confirm the amount claimed on your SA106.


Q10. Can you claim FTCR if the foreign country doesn’t have a tax treaty with the UK?

A. Yes, you can still claim FTCR under unilateral relief rules if there’s no treaty, as long as the tax is similar to UK income tax, per HMRC guidance in 2025.

Q11. What’s the penalty for submitting an incorrect SA106 form due to honest error?

A. For honest mistakes, HMRC may charge a penalty of up to 30% of the tax due if reasonable care wasn’t taken, but you can appeal with evidence of good faith.


Q12. Do you need a tax adviser to complete the SA106 form?

A. No, it’s not mandatory, but if your foreign income is complex (e.g., multiple countries or offshore trusts), a tax adviser can help avoid errors, costing £200-£500 typically in 2025.


Q13. How long does HMRC keep your SA106 records on file?

A. HMRC retains your tax records, including the SA106, for at least 6 years after the tax year, or longer if under investigation, as per 2025 regulations.


Q14. Can you file the SA106 if you’re a dual citizen with income in both countries?

A. Yes, as a UK resident, you must file the SA106 for non-UK income, and your dual citizenship doesn’t exempt you—treaties determine tax liability.


Q15. What happens if you overclaim Foreign Tax Credit Relief on the SA106?

A. HMRC can demand repayment of excess relief, plus interest, and may impose a penalty of up to 30% of the overclaimed amount if it’s deemed careless.


Q16. Do you need to report foreign income below a certain threshold on the SA106?

A. Yes, there’s no minimum threshold—all foreign income must be reported, though small amounts might not trigger tax if covered by allowances or reliefs.


Q17. Can you use the SA106 to claim losses from foreign investments?

A. No, the SA106 is for income and gains; foreign investment losses are typically reported on other Self-Assessment pages like SA103 or SA108, depending on the source.


Q18. How do you appeal an HMRC decision about your SA106 if you disagree?

A. You can request a review within 30 days of HMRC’s decision or appeal to the First-tier Tribunal within the same timeframe, providing evidence like tax documents.


Q19. What’s the difference between remitted and unremitted income for SA106 purposes?

Q20. Can you file the SA106 if you’re self-employed and paid by foreign clients in the UK?

A. No, if the income is paid into the UK for work done here, it’s UK income reported on SA103, not foreign income for the SA106—location of payment matters.
