UK Tax Filing Basics for NRIs
This page is an orientation, not a substitute for the detailed guides on DTAA, account reporting, or property sales. It's here to connect the dots: what a UK tax resident with India-source income actually has sitting on their plate each filing season, and which of the other guides in this section covers each piece in depth.
This guide explains how the rules generally work and is not tax, legal, or investment advice. Rates, thresholds, and form numbers change with each Union Budget and Finance Act, and your own situation (which country you live in, your visa or citizenship status, how the asset was funded) can change the answer. Confirm your specific case with a chartered accountant or tax advisor before you file anything or move money.
The starting principle: worldwide income, once you're UK tax resident
Once you meet the Statutory Residence Test, the UK taxes your worldwide income, not just UK-source income. That means NRO interest, dividends from Indian investments, rental income from Indian property, and capital gains from selling Indian assets all generally belong on your Self Assessment return, in addition to whatever India requires. NRE interest belongs there too, even though it's exempt from Indian tax, since that exemption has no bearing on UK taxability. This single fact, worldwide income once resident, is what makes NRI tax filing genuinely more complex than either country's rules alone, and it's the reason the Statutory Residence Test matters so much: it's the switch that turns this on.
The pieces, and where each is covered
- Avoiding double taxation on India-source income: get a Certificate of Residence from HMRC plus India's Form 41 self-declaration, then claim Foreign Tax Credit Relief on SA106 for the Indian tax actually paid. New arrivals should also check eligibility for the Foreign Income and Gains regime. Covered in the UK-India DTAA guide.
- Reporting your NRE/NRO accounts: no standalone balance-reporting form exists in the UK, but the underlying interest must still be declared, and HMRC receives account data automatically through the Common Reporting Standard regardless. Also covered in the DTAA guide.
- Selling property in India: India withholds tax at the sale (TDS), and you'd generally claim UK Foreign Tax Credit Relief for that against any UK tax on the same gain, remembering that the treaty doesn't cap the capital-gains rate the way it caps dividends and interest. See Selling Property in India as an NRI for the India side of this.
- Withdrawing EPF or EPS: India's tax-free-after-5-years rule and the EPS pension mechanics are covered in What Happens to Your PF Account When You Move Abroad. How the withdrawal should be treated on a UK return is a good specific question for an accountant familiar with Indian retirement accounts.
- Sending money between the two countries: not itself a UK tax event for routine transfers of your own funds, but see How to Send Money From the UK to India for the cost side, and note that large gifts can factor into UK Inheritance Tax rules if the giver passes away within seven years.
Key Self Assessment deadlines
- 5 October: register for Self Assessment if this is your first year needing to file for the previous tax year.
- 31 October: paper return deadline, if filing on paper.
- 31 January: online filing deadline and the deadline to pay any balance owed.
- Forms: SA100 (main return) plus SA106 (Foreign pages) for India-source income, and SA109 if you're claiming the Foreign Income and Gains regime as a recent arrival.
Why the order of operations matters
Handle the India-side DTAA claim first where you can. Getting Form 41 and your Certificate of Residence in place before India withholds tax means less gets withheld at source, and it leaves a cleaner, verifiable figure to claim as Foreign Tax Credit Relief on the UK side. Filing the India side late, or not at all, tends to cost money on both ends of the process, not just one.
Frequently asked questions
How does the UK decide if I count as a tax resident at all?
Through the Statutory Residence Test. Automatic tests based mostly on day count settle most cases either way (very few days in the UK generally means non-resident, 183 or more days generally means resident). When those don't resolve it, a 'sufficient ties' test combines your day count with UK connections like family, accommodation, and work, with more ties required to become resident the fewer days you spend in the country.
I've only just arrived in the UK. Does that change anything?
Possibly, in your favor. If you weren't UK tax resident in the 10 years before you arrived, you can generally claim the Foreign Income and Gains regime for your first four years of residence, giving full relief on foreign income and gains rather than just a credit for Indian tax already paid. Covered in the UK-India DTAA guide.
Where do I start if I've never reported Indian income on a UK return before?
Register for Self Assessment by 5 October following the tax year you need to report, and talk to an accountant experienced with UK/India cross-border tax before your first filing. FIG eligibility, Foreign Tax Credit Relief claims, and your residency status all interact, and getting the order wrong on a first filing is a common, avoidable mistake.
