In short

  • File if you have self-employment, rental, or foreign income.
  • HMRC records are documentary evidence used in settlement and citizenship applications.
  • Online returns are due by 31 January after the end of each tax year.
  • Register with HMRC as soon as you start receiving untaxed income.
  • Keep copies of all tax returns and correspondence from HMRC.

Some visa holders need to file self-assessment tax returns if they have self-employment income, rental income, or other untaxed income. Tax records are also documentary evidence used in settlement and citizenship applications. This guide covers the essentials.

When You Need to File

Most employees in the UK are taxed through PAYE (Pay As You Earn), where your employer deducts tax before paying you. If all your income comes from PAYE employment, you typically do not need to file a self-assessment return.

You do need to file if you:

  • Are self-employed and earned more than 1,000 pounds before expenses (where your visa permits self-employment)
  • Receive rental income from UK or overseas property
  • Have income from overseas
  • Are a partner in a business partnership, or an off-payroll worker repaying a student or postgraduate loan
  • Have capital gains tax to pay
  • Have to pay the high income child benefit charge
  • Receive income from investments, savings, dividends, tips or commission that has not been taxed already
  • Need to claim certain tax reliefs

How to Register and File

  1. Register for self-assessment with HMRC on GOV.UK. You will need your National Insurance number.
  2. HMRC will send you a Unique Taxpayer Reference (UTR) number. GOV.UK does not publish a fixed processing time; its "check when you can expect a reply from HMRC" tool gives the current wait.
  3. Create a Government Gateway account if you do not already have one.
  4. Complete your tax return online (or on paper, though online is faster and has a later deadline).
  5. Pay any tax owed by the deadline.

You need a National Insurance number to register. If you do not have one yet, apply for one first.

Key Deadlines

  • 5 October: Deadline to register for self-assessment if you are new to it.
  • 31 October: Paper return deadline.
  • 31 January: Online return deadline and payment deadline.
  • 31 July: Second payment on account deadline (if applicable).

Filing late brings an automatic 100 pound penalty. After 3 months there are daily penalties of 10 pounds a day up to 900 pounds; after 6 months a further 5% of the tax due or 300 pounds, whichever is greater; and after 12 months another 5% or 300 pounds, whichever is greater. Paying late brings a penalty of 5% of the unpaid tax at 30 days, at 6 months and at 12 months, plus interest.

Tax Records and Immigration

Your self-assessment tax returns are valuable evidence for immigration applications:

Keep copies of every tax return you file and every tax calculation or statement from HMRC. Download SA302 (tax calculation) and tax year overview documents from your HMRC online account.

Common Mistakes

  • Not registering in time: Register by 5 October after the end of your first tax year with untaxed income.
  • Forgetting foreign income: UK residents must declare worldwide income. Income from overseas bank accounts, rental property, or employment must be included.
  • Not keeping records: HMRC requires self-employed records to be kept for at least 5 years after the 31 January submission deadline for that tax year.
  • Missing the deadline: Set reminders. The 31 January deadline is firm and penalties apply immediately.

Next Steps

Questions and answers

Do I need to file a self-assessment tax return on a UK visa?

HMRC lists the situations that require a return: self-employment income of more than 1,000 pounds before expenses, being a business partner, capital gains tax to pay, the high income child benefit charge, and untaxed income such as rent, tips, commission, savings interest, dividends or foreign income. Most employees paid through Pay As You Earn do not need to file unless they have additional income. The old rule that a salary above 150,000 pounds taxed only through Pay As You Earn meant you had to file no longer applies.

How do self-assessment returns help with immigration?

Tax returns are documentary evidence of income and of time spent in the UK. Several routes ask for them by name: the Appendix FM financial requirement lists self-assessment tax returns among the specified evidence for self-employed sponsors, and settlement and citizenship applications ask about tax compliance. What each application needs is set out in its own published guidance.

What are the self-assessment deadlines?

The tax year runs from 6 April to 5 April. Paper returns are due by 31 October after the tax year ends. Online returns are due by 31 January. Late filing results in automatic penalties.

Can I file a self-assessment return if I am self-employed on my visa?

Only certain visa types permit self-employment. If your visa allows self-employment and you are self-employed, you must register for self-assessment and file annual returns. See our guide on self-employment visa types for which visas permit this.
