SA700 Tax Form – Complete Guide to Filing a Non-Resident UK Tax Return

Understanding the SA700 Form

If you live outside the UK but receive income from UK sources, you may still need to file a tax return. The SA700 form is the official document used to declare income earned in the United Kingdom by individuals who are non-resident for tax purposes.

This guide explains everything you need to know — who needs to complete it, how to fill it in, what documents to prepare, and how to submit it safely to HMRC. Whether you’re working abroad, receiving UK property income, or have investment earnings, this walkthrough will help you understand your responsibilities and how to stay compliant with HMRC rules.

What Is the SA700 Form?

The SA700 form is a Non-Resident UK Tax Return. It allows individuals who live abroad to report UK income and pay any tax due — or claim a refund if too much has been deducted.
You’ll typically need to complete this form if you are:

• Living abroad for most or all of the tax year, and

• Receiving UK income such as property rent, pensions, or interest, and

• Not required to file a full Self Assessment return (for example, you don’t have UK self-employment income).

Who Must Complete the SA700?

You must submit the SA700 if any of the following apply:

• You are a non-resident landlord receiving rental income from UK property.

• You receive UK bank interest or dividends where tax was deducted.

• You receive a UK pension or annuity while living abroad.

• You have UK-based investment income, royalties, or other taxable returns.

• You are a retired person abroad with a private or occupational pension from the UK.

• You are a foreign national who once worked in the UK and still receives income from a UK source.

If you are unsure whether you qualify as a non-resident, HMRC’s official residency tests can help you check:

Documents You’ll Need Before You Start

Gather these before completing the form:

• Your National Insurance number (if you have one)

• Your Unique Taxpayer Reference (UTR), if previously registered with HMRC

• Details of all UK income (rent, pension, dividends, etc.)

• Certificates showing tax deducted at source

• Foreign address and proof of residence outside the UK

• Details of any double taxation relief (if applicable)

• UK bank details for potential refunds

Having this information ready helps avoid delays.

How to Complete the SA700 Form – Step by Step

Step 1: Download the Form

Download the latest SA700 form 2025 directly from HMRC’s website:
https://www.gov.uk/government/publications/self-assessment-non-resident-company-income-tax-return-sa700

Step 2: Personal and Residency Details

Fill in your full name, date of birth, and overseas address. Indicate your country of residence and specify the dates you were outside the UK during the relevant tax year.

You will also be asked whether you consider yourself resident under the Statutory Residence Test (SRT) — if you’re unsure, use HMRC’s online tool:
https://www.gov.uk/check-immigration-status

Step 3: Declare Your UK Income

Report all UK-sourced income for the tax year:

• Rental income from UK property

• UK pensions, annuities, or state benefits

• Bank or building society interest

• Dividends from UK companies

• Royalties or licensing payments

Include any tax already deducted. If you have income in foreign currency, convert it to pounds sterling using the official exchange rate for the tax year (found at https://www.gov.uk/government/collections/exchange-rates-for-customs-and-vat).

Step 4: Claim Reliefs and Allowances

If your country has a Double Taxation Agreement (DTA) with the UK, you may be entitled to partial or full tax relief. The form includes sections for you to claim relief under specific treaty articles.
You can find the full list of UK DTAs at:
https://www.gov.uk/government/collections/tax-treaties

Step 5: Calculate Your Tax or Refund

The SA700 form allows you to offset UK tax deducted against what’s due. If you’ve overpaid, HMRC will arrange a refund.

Step 6: Sign and Submit

You can post the completed form to HMRC:
HM Revenue and Customs, PT Operations North East England, BX9 1AS, United Kingdom

Make sure to sign the declaration page and date it clearly. Unsigned or undated returns will not be processed.

Deadlines for Submitting the SA700

• Paper submission deadline: 31 October following the end of the tax year.

• Online submission (via authorised agent): 31 January.
  Late filing may result in penalties.

If you cannot file on time, you should contact HMRC to explain the delay as soon as possible:
https://www.gov.uk/self-assessment-tax-returns/penalties

Processing Time

HMRC typically processes SA700 forms within 8–12 weeks, though this can vary depending on whether you’re claiming a refund or paying additional tax. If your refund involves foreign bank transfers, processing may take slightly longer.

You can track correspondence by registering for a personal tax account:

Common Issues That Cause Delays

• Forgetting to tick the “non-resident” box

• Using outdated forms

• Missing information about Double Taxation Agreements

• Not providing proof of foreign address

• Not converting foreign income to GBP

Having your form reviewed before submission can prevent most of these errors.

Double Taxation Relief and the SA700

Many non-residents worry about paying tax twice — once in the UK and once in their home country.
The UK has Double Taxation Agreements (DTAs) with over 130 countries to prevent this.

If you’ve already paid tax abroad on your UK income, you may be able to offset it. To claim relief, include details in the appropriate SA700 section and attach any foreign tax certificates.

How Refunds Are Paid

HMRC can issue refunds:

• Directly into a UK bank account (preferred)

• By cheque to a UK or overseas address

Refunds to overseas accounts may take longer, especially if the currency differs.

Avoiding Common Mistakes

• Do not include foreign (non-UK) income unless specifically requested.

• Always use the latest version of the form for the correct tax year.

• Check that all pages are signed and dated.

• Ensure your address abroad is clear and complete (including postcode or postal code equivalent).

• Do not send original certificates — use copies.
