NRI ITR Filing Deadline 2026: Complete Guide for UK Residents

Two Tax Deadlines. Two Tax Authorities. One Set of Income.

UK-based NRIs face a compliance challenge that most tax guides underestimate: you are potentially dealing with two filing deadlines, two tax authorities, and a treaty designed to prevent double taxation that requires active claiming on both sides to work properly.

The Indian deadline is 31 July 2026 for most NRIs filing for Assessment Year 2026-27 (Financial Year 2025-26). The UK Self Assessment deadline is 31 January 2027 for the 2025-26 UK tax year (6 April 2025 to 5 April 2026). These do not perfectly align, and the mismatch creates sequencing questions worth thinking through in advance.

This guide covers both deadlines, explains how the India-UK DTAA works in practice, and walks through the filing process on both sides.

Key Dates at a Glance

Indian ITR Deadlines (Assessment Year 2026-27)

| Deadline | Date | What It Means | |---|---|---| | End of Indian Financial Year | 31 March 2026 | FY 2025-26 closes. All Indian-source income up to this date is in scope. Last day for Section 80C tax-saving investments. | | ITR Filing Deadline (NRIs) | 31 July 2026 | The main deadline for filing your Indian ITR without a late fee. File before this date. | | Belated Return Deadline | 31 December 2026 | Late filing is permitted but incurs a fee of up to ₹5,000 (₹1,000 if total income below ₹5 lakh) under Section 234F, plus interest on unpaid tax. | | Revised Return Deadline | 31 December 2026 | If you filed on time but need to correct errors, file a revised return by this date. | | Advance Tax Deadlines | 15 June, 15 Sept, 15 Dec, 15 March | Quarterly advance tax payments required if your Indian tax liability after TDS exceeds ₹10,000. |

UK Self Assessment Deadlines (Tax Year 2025-26)

| Deadline | Date | What It Means | |---|---|---| | UK Tax Year End | 5 April 2026 | The 2025-26 UK tax year closes. Note: UK tax year runs 6 April to 5 April — five days after India's year-end. | | Register for Self Assessment | 5 October 2026 | If this is your first year with untaxed income from India, you must register by this date. | | Paper Return Deadline | 31 October 2026 | If filing a paper Self Assessment (unusual), this is the deadline. | | Online Return Deadline | 31 January 2027 | The main deadline for online Self Assessment filing for 2025-26. | | Payment Deadline | 31 January 2027 | Any tax owed for 2025-26 must be paid by this date to avoid interest and penalties. | | Payments on Account | 31 January and 31 July | If your SA tax bill is above £1,000, HMRC may require advance payments on account toward the following year. |

The Sequencing Advantage

The UK deadline (31 January 2027) falls six months after the Indian deadline (31 July 2026). This is advantageous: you can file your Indian ITR first, receive your Indian tax computation, and use the confirmed figures when completing SA106 on your UK return. You are not guessing at Indian tax paid — you have a completed Indian assessment to reference.

Do You Need to File an Indian ITR?

Not every UK NRI is legally required to file, but many who are not required should file anyway.

You Must File If:

• Your total Indian income exceeds ₹2.5 lakh in FY 2025-26 — this includes NRO FD interest, rental income, capital gains, dividends, and salary from an Indian employer
• TDS was deducted on your Indian income and you want to claim a refund — banks deduct TDS at 30%–31.2% on NRO interest, which is often more than your actual liability
• You sold Indian property, shares, or mutual funds and need to report capital gains
• You have business or professional income from India

You Are Not Required to File If:

• Your only Indian income is NRE FD interest, which is fully tax-exempt in India
• Your total Indian income is below ₹2.5 lakh and no TDS was deducted on any income

Why Filing Voluntarily Makes Sense

Even when not required, filing creates a clean compliance record. It starts the assessment window clock — the tax department generally cannot reopen your case after several years from filing. It also makes future Indian financial transactions (home loan applications, property sales, repatriation of funds) significantly easier. A history of filed returns is expected by Indian banks and property registrars.

Which ITR Form Should UK NRIs Use?

| ITR Form | Who Should Use It | |---|---| | ITR-1 (Sahaj) | Residents only. NRIs cannot use ITR-1 under any circumstances. | | ITR-2 | NRIs with salary from Indian employer, house property income, capital gains, FD interest, dividends, or other sources. This is the correct form for most UK NRIs. | | ITR-3 | NRIs with business or professional income in India (consulting, partnership, proprietorship). | | ITR-4 (Sugam) | Resident individuals under presumptive taxation. Not applicable to NRIs. |

For the vast majority of UK NRIs, ITR-2 is the correct form. It covers rental income, NRO FD interest, capital gains from stocks and property, and dividends. Only use ITR-3 if you have genuine business income in India.

Step-by-Step: Filing Your Indian ITR for AY 2026-27

Whether you use ClearTax, Tax2Win, or the Income Tax portal directly, the process follows the same steps.

Step 1: Gather Your Documents

Identity and Residency:

• PAN card
• Valid passport (travel history may be needed to confirm residential status)
• UK visa, BRP, or British passport
• Dates of entry and exit from India during FY 2025-26

Income Documents:

• Bank statements for all NRE and NRO accounts (April 2025 – March 2026)
• Form 16A (TDS certificates from banks and tenants)
• Capital gains statements from Indian brokers and mutual fund houses
• Form 16 if you had Indian salary income

For DTAA Claims:

• Tax Residency Certificate from HMRC — this is your proof of UK tax residency and must be submitted to your Indian bank and the Income Tax Department
• Form 10F (self-declaration of details not covered in the TRC)
• UK P60 or Self Assessment return for cross-reference

Step 2: Confirm Your Residential Status

Your Indian tax liability depends on your residential status under the Income Tax Act. The key threshold: if you were in India for fewer than 182 days during FY 2025-26, you are a Non-Resident for Indian tax purposes. Most UK-based NRIs clear this easily.

If you spent significant time in India during the year — caring for a parent, extended visits — recount carefully. An unintentional overstay can change your status and expose your worldwide income to Indian tax.

The more complex RNOR (Resident but Not Ordinarily Resident) category applies during the transitional years when NRIs return to India permanently. Most UK NRIs filing from abroad will be straightforwardly Non-Resident.

Step 3: Log In to the Income Tax Portal

Visit incometax.gov.in and log in with your PAN. UK phone numbers are accepted for OTP verification.

Step 4: Download Form 26AS and AIS

Form 26AS shows all TDS deducted on your behalf. Annual Information Statement (AIS) provides a broader view of your Indian financial activity. Compare both against your own records before filing. TDS discrepancies between your records and 26AS will delay refunds — catch them before submitting the return.

Step 5: Fill ITR-2

Key schedules to complete:

• Personal Information — Select "Non-Resident" as your residential status
• Schedule HP — House property income (rental income minus 30% standard deduction, minus home loan interest if applicable)
• Schedule CG — Capital gains from property, shares, or mutual funds
• Schedule OS — Other sources: NRO FD interest and dividends
• Schedule FSI — Foreign source income, if any (relevant for RNOR or if claiming DTAA benefits)
• Schedule TR — Tax relief under DTAA (Article references for India-UK treaty)
• Schedule FA — Foreign assets (primarily for RNOR, but understand its scope)

Step 6: File Form 67 for DTAA Claims

This is the step most UK NRIs miss — and it is expensive to miss. If you are claiming relief under the India-UK DTAA, Form 67 must be filed before or alongside your ITR. Filing it after the fact may result in the claim being rejected.

Form 67 requires:

• Your Tax Residency Certificate from HMRC
• Details of UK income and UK tax paid on Indian income (if any)
• Declaration of the DTAA article under which you claim relief

Services like ClearTax and Tax2Win handle Form 67 as part of their NRI filing plans. This alone justifies the cost of professional assistance for most UK NRIs.

Step 7: Review, Submit, and E-Verify

Review the auto-calculated tax computation. Verify TDS credits match Form 26AS. Submit the return. You must then e-verify within 30 days. Options for UK-based NRIs:

• Net banking through your Indian bank — most reliable option for NRIs abroad
• Aadhaar OTP — only if your Aadhaar is linked to your Indian mobile number
• Digital Signature Certificate
• Physical verification — send signed ITR-V to CPC Bangalore by post (slowest; avoid if possible)

The India-UK DTAA in Practice

The Convention for the Avoidance of Double Taxation between India and the UK (signed 1993) is the legal framework preventing both countries from taxing the same income. Understanding how it applies to common NRI income is essential.

DTAA Coverage for Common UK NRI Income

| Income Type | India Tax Position | UK Tax Position | DTAA Relief | |---|---|---|---| | NRE FD interest | 100% exempt | Taxable as savings income | No relief needed (only taxed in UK) | | NRO FD interest | TDS at 30% (15% with TRC) | Taxable; foreign tax credit for Indian TDS | SA106 Foreign Tax Credit Relief | | Rental income | Taxable; TDS by tenant at 31.2% | Taxable; credit for Indian tax paid | SA106 Foreign Tax Credit Relief | | Dividends (Indian stocks) | Taxable in India | Taxable in UK; credit for Indian tax | SA106 Foreign Tax Credit Relief | | Short-term capital gains (shares/MF) | Taxable at 20% (post-July 2024 rate) | Taxable in UK | SA106 Foreign Tax Credit Relief | | Long-term capital gains (property) | Taxable at 12.5% (post-July 2024 rate) | Taxable in UK | SA106 Foreign Tax Credit Relief | | Salary from Indian employer | Taxable in India; TDS applies | Taxable in UK if UK-resident | Foreign tax credit in UK |

Note: Indian capital gains tax rates were revised by the Union Budget 2024. LTCG on property is now 12.5% (without indexation). STCG on equity is 20%. Verify current rates before filing.

Claiming DTAA Benefits: The Complete Process

In India:

1. Obtain a Tax Residency Certificate from HMRC (apply via your HMRC online account or by writing to HMRC's CAAT team)
2. Submit the TRC and Form 10F to your Indian bank — bank will then apply 15% TDS on NRO interest rather than 30%
3. File Form 67 with the Income Tax Department before or with your ITR
4. Complete Schedule TR in ITR-2 citing the relevant DTAA article

In the UK:

1. Declare Indian income on SA106 (Foreign Income section of Self Assessment)
2. Complete the Foreign Tax Credit Relief section of SA106 with details of Indian taxes paid
3. HMRC will credit the Indian tax against your UK liability on the same income, so you pay the higher of the two rates, not both stacked

The UK Tax Year Timing Issue

The UK tax year runs 6 April to 5 April. The Indian financial year runs 1 April to 31 March. The gap is five days. This creates a small misalignment for income earned in the first five days of April — income from 1–5 April 2025 falls in Indian FY 2024-25 (AY 2025-26) but in UK tax year 2025-26.

For practical purposes, most UK NRIs treat the years as aligned. The five-day overlap rarely produces material amounts of income. If you have significant income accruing in the first five days of April (a fixed deposit maturing, for instance), note the difference and reflect it correctly in both returns.

Filing Your UK Self Assessment: SA106 Explained

If you have Indian income of any kind, you need to complete SA106 (Foreign Income) as part of your UK Self Assessment return.

What SA106 Covers

SA106 has sections for:

• Foreign interest — NRE and NRO FD interest, savings account interest
• Foreign dividends — dividends from Indian stocks and mutual funds
• Foreign property income — rental income from Indian property
• Foreign Tax Credit Relief — claim here for Indian taxes paid (TDS)

Capital gains from Indian assets (property, shares) are reported on SA108 (Capital Gains), not SA106. If you sold Indian property or shares, you will need both forms.

Practical Steps for SA106

1. Convert INR income to GBP using HMRC's published exchange rates for the year, or the actual rates at which income was received. For FY 2025-26 income, use HMRC's official GBP/INR rates for the UK 2025-26 tax year.
2. Identify Indian tax paid from your TDS certificates (Form 16A) and Indian ITR computation.
3. Enter income and tax paid in the relevant SA106 sections.
4. Claim Foreign Tax Credit Relief — HMRC will compute the relief automatically based on what you enter.
5. Keep all documentation — TDS certificates, Form 16A, bank statements, and your Indian ITR acknowledgement receipt. HMRC can request evidence.

Non-Dom Changes: Impact on Indian Income

The UK abolished the remittance basis for non-domiciled residents from 6 April 2025. This change affects how Indian income is treated for UK tax purposes:

• Pre-April 2025 arrivals who claimed non-dom status: The old remittance basis is no longer available. You are now taxed on worldwide income as it arises. Indian income — including NRE interest — must be declared as it accrues, not when you bring it to the UK.
• New arrivals after 6 April 2021: The Foreign Income and Gains (FIG) relief may apply for your first four qualifying tax years, exempting foreign income from UK tax during that window. This relief requires an active election each tax year and is not automatic.
• Arrivals before April 2021: You are fully on the arising basis. All worldwide income is taxable in the UK as it accrues.

If you previously relied on the remittance basis to defer UK tax on Indian income, your position has changed materially. Take specialist advice if you are uncertain.

Penalties for Missing Deadlines

Indian Side (Section 234F)

| Scenario | Penalty | |---|---| | File after 31 July but before 31 December 2026 | ₹5,000 late fee (₹1,000 if total Indian income below ₹5 lakh) | | Not filing at all | Late fee + interest under Sections 234A, 234B, 234C + loss of ability to carry forward capital losses | | Interest on unpaid tax | Section 234A: 1% per month on unpaid tax from due date | | Capital loss carry-forward | Cannot carry forward capital losses if ITR filed after 31 July deadline |

UK Side

| Scenario | Penalty | |---|---| | Miss 31 January 2027 online deadline | £100 automatic penalty | | 3 months late | £10 per day (up to £900) | | 6 months late | £300 or 5% of tax due, whichever is higher | | 12 months late | Further £300 or 5% of tax due | | Deliberate non-disclosure | Up to 100% of tax due as penalty | | Interest on unpaid tax | Bank of England base rate + 2.5% on tax unpaid after 31 January |

Filing both returns on time — July 31 for India, January 31 for the UK — avoids all of the above.

Should You Use a Professional Service?

For most UK NRIs, the answer is yes. Professional filing through ClearTax (₹5,999–₹9,999) or Tax2Win (₹4,999–₹7,999) is cheap relative to the cost of errors. These services assign a qualified chartered accountant who handles ITR-2 filing, Form 67, and DTAA documentation as a package.

Use a professional service if:

• You have income from multiple Indian sources (rent, FD interest, capital gains)
• You are claiming DTAA benefits — Form 67 handling alone justifies the cost
• You sold Indian property or shares and need capital gains calculation
• This is your first year filing as an NRI
• You want the return reviewed by a CA before submission

Consider self-filing if:

• Your only Indian income is NRO FD interest with TDS already deducted
• You are not claiming DTAA benefits
• Your return is genuinely simple and you are comfortable on the Income Tax portal

Note on the UK side: For the SA106 element of your UK Self Assessment, consider using a UK accountant experienced with NRIs. The DTAA foreign tax credit calculations on SA106 are straightforward once you have your Indian ITR confirmation, but the non-dom rule changes make 2025-26 a year where professional guidance is more valuable than usual.

Filing Timeline: When to Do What

| Month | Action | |---|---| | March 2026 | Last chance for Section 80C, 80D tax-saving investments in India before FY 2025-26 ends on 31 March. | | April 2026 | Collect Indian documents: NRE/NRO bank statements, TDS certificates (Form 16A), capital gains statements, Form 16. Request your Tax Residency Certificate from HMRC. | | May 2026 | Start Indian ITR process. If using ClearTax or Tax2Win, upload documents and connect with your CA early — less queue pressure in May than July. | | June 2026 | Review draft Indian ITR computation from CA. File Form 67 if claiming DTAA benefits. Note: Form 67 should be filed before ITR submission. | | Early July 2026 | Submit Indian ITR. Do not leave it to 31 July — the Income Tax portal routinely slows and crashes in the final days before the deadline. File by 15 July to be safe. | | Within 30 days of filing | E-verify your Indian ITR via net banking. | | October 2026 | Register for UK Self Assessment if not already registered (deadline 5 October). | | November–December 2026 | Compile UK Self Assessment with Indian ITR confirmation documents. Begin SA106 and, if applicable, SA108 preparation. | | January 2027 | Submit UK Self Assessment and pay any tax owed by 31 January. | | 31 December 2026 | Last day to file a revised Indian ITR if you need to correct errors made in the July filing. |

Frequently Asked Questions

Do UK NRIs need to file an Indian ITR if their only Indian income is NRE FD interest?

No. NRE FD interest is fully exempt from Indian tax and does not count toward the ₹2.5 lakh threshold. If this is your only Indian income and no TDS was deducted, you are not required to file an Indian ITR. You must, however, declare the NRE interest on your UK Self Assessment as foreign savings income — it is taxable in the UK even though it is exempt in India.

Which ITR form should UK NRIs use?

ITR-2 for most cases — it covers rental income, NRO FD interest, capital gains from property and equity, dividends, and salary from an Indian employer. NRIs cannot use ITR-1 (residents only). ITR-3 applies only if you have business or professional income in India.

How do I claim India-UK DTAA benefits in India?

You need a Tax Residency Certificate from HMRC, Form 10F (self-declaration), and Form 67 filed with the Income Tax Department before or alongside your ITR. File Form 67 first — filing it after your ITR can result in the DTAA claim being rejected. The TRC and Form 10F also go to your Indian bank to reduce TDS on NRO interest from 30% to 15%.

What is Form SA106 and do I need it?

SA106 is the Foreign Income supplementary page of the UK Self Assessment return. If you received any income from India — interest, rent, dividends — you must complete SA106 when filing your Self Assessment. SA106 also contains the Foreign Tax Credit Relief section, where you declare Indian taxes paid (TDS) to avoid being taxed twice on the same income. Capital gains from Indian assets go on SA108 instead.

What is the penalty for missing the Indian ITR deadline?

Filing after 31 July 2026 but before 31 December 2026 triggers a ₹5,000 late fee under Section 234F (₹1,000 if total income is below ₹5 lakh), plus interest on any unpaid tax at 1% per month under Section 234A. You also lose the ability to carry forward capital losses, which can be costly if you had significant equity or property transactions. Not filing at all risks further penalties and, for chronic non-filers, potential prosecution.

How does the UK's abolition of non-dom status affect NRI tax filing?

From 6 April 2025, the remittance basis of taxation for non-doms was abolished. Most UK residents are now taxed on worldwide income as it arises. If you relied on the remittance basis to defer UK tax on Indian income — including NRE FD interest — that option is no longer available (for most people). New arrivals from India who entered the UK after 6 April 2021 may qualify for the Foreign Income and Gains (FIG) relief for their first four qualifying tax years. If you are close to any of these thresholds, take professional advice.

Can I file both my Indian ITR and UK Self Assessment myself?

Yes, both portals are accessible from the UK. The Indian e-filing portal (incometax.gov.in) accepts OTPs to UK mobile numbers, and e-verification via Indian net banking works from abroad. For UK Self Assessment, HMRC's online portal or commercial tax software both handle SA106. The complexity is not in the mechanics — it is in correctly applying DTAA benefits, Form 67, and the non-dom rule changes. For most UK NRIs with more than simple NRO interest income, a CA-assisted Indian filing plus a UK accountant familiar with foreign income is a sensible investment.
