Filing of UK Tax Returns for NRIs

For NRIs earning income in the UK, filing a tax return can feel complex – especially when income is received from multiple sources such as properties, investments, capital gains or employment. Understanding UK tax rules, return deadlines, reporting formats, and tax relief becomes crucial to stay compliant and avoid penalties.

FinPracto assists NRIs, OCI cardholders and foreign residents with end-to-end support in filing UK self-assessment tax returns, ensuring full compliance and tax efficiency. Whether you have UK-based rental income, have sold a property, or receive income from investments or employment, our specialised UK tax team ensures hassle-free filing from anywhere in the world.

Who Should File a UK Tax Return?

An NRI needs to file a UK tax return if they have income arising from:

  • Rental income from residential or commercial property in the UK
  • Profit earned from selling property or other assets situated in the UK
  • Employment income, consultancy earnings or freelance income
  • Dividends, interest or other UK-sourced investment income

Even if the tax has already been deducted at source, filing a return may help secure refunds and avoid compliance issues.

Important Tax Deadlines

Mode of Filing Deadline
Paper Filing 31 October (following end of tax year)
Online Filing 31 January (following end of tax year)

Late filing attracts automatic penalties which increase over time, making timely submission essential.
