The NRI calendar your CA never gave you. The dates that matter, real money behind each.

Resident Indians have one big deadline: ITR by 31 July under Section 139. That's basically it.

NRIs have many more. The reason is structural. You're being taxed in India and in your home country, with a treaty between them. Each treaty document, TRC, Form 10F, FATCA self-certification, has its own clock. Miss one and your bank either freezes the account, deducts 30% TDS instead of treaty rate, or both.

The penalties aren't theoretical. A typical case: the Form 10F on file was out of date when a Q1 dividend was paid, and the company deducted 20% plus surcharge and cess instead of the 10% treaty rate. That's the real money behind a missed date.

Still ahead this year: 21 October (tax audit report, if you have Indian business income that needs an audit), 31 October (deductors' Q2 TDS returns), 31 December (last date for a belated return), and 31 March (Section 119(2)(b) refund condonation cut-off).

Here's the year laid out by month, with what each deadline is and what happens if you miss it.

1 April: a fresh Form 41 (formerly Form 10F) is needed for the new tax year, along with a TRC that covers it. Filing takes 5 minutes if your TRC is in hand.

TRC periods differ by country: a UK certificate covers the UK tax year (6 April to 5 April), others follow the calendar year or run from the date of issue, so check what period yours covers.

31 May: the deductor's TDS return for January to March (Form 27Q for FY 2025-26; Form 144 from FY 2026-27) is due. You don't file this, your bank or AMC does, but it is what puts the Q4 TDS on your 26AS before you file.

Penalty for missing the refile: the bank falls back to the domestic TDS rate (about 30% on NRO interest) instead of the treaty rate. The excess is recoverable through your return, but only if you catch it in time.

31 July: ITR-2 due for NRIs with no business or professional income, such as rent, interest and capital gains. If you have Indian business or professional income that is not audited, the due date is 31 August from AY 2026-27. Schedule FA (foreign assets) applies only once you are Resident and Ordinarily Resident (ROR); NRIs filing as non-residents do not file it.

Miss 31 July: you can still file a belated return under Section 139(4) until 31 December, but you lose the carry-forward of business and capital losses (a house-property loss still carries forward).

Miss 31 December: the belated return window closes. From AY 2026-27 a return already filed can still be revised until 31 March of the assessment year under Section 139(5) (Section 263(5) of the Income-tax Act 2025 from tax year 2026-27), with a fee of ₹1,000 or ₹5,000 if revised after 31 December. For AY 2025-26 and earlier the revision limit was 31 December. Once the belated window has closed, the routes left are an updated return, which cannot claim a refund, or a Section 119(2)(b) condonation application for a refund.

31 July: deductors' TDS returns for April to June are due. Your Q1 TDS should then show on 26AS.

From August: Section 143(1) intimations for filed returns go out on a rolling basis. If you filed a refund claim, the intimation either matches your computation or differs. A mismatch typically means a TDS line on AIS missing from 26AS: fix it at the deductor's end and respond within the time the intimation gives.

21 October 2026 (extended from 30 September for AY 2026-27): tax audit report due, if your Indian business or profession crosses the Section 44AB limits. This does not depend on your residential status. The return for an audited case is then due by 21 November 2026 (extended from 31 October).

31 October: TDS Q2 returns from deductors. TDS for July to September should be on 26AS by mid-November.

31 December: last date for a belated return under Section 139(4). A return can be revised until 31 March from AY 2026-27, with a fee after 31 December.

31 January: deductors' TDS returns for October to December.

January to March: the last weeks to issue a Section 148A show-cause notice for AY 2023-24 (3 years from the end of the AY) and, where the escaped income is ₹50 lakh or more, for AY 2021-22 (5 years). The Section 148 notice itself can follow up to 3 months later. These are the limits set by the Finance (No. 2) Act 2024 from 1 September 2024. Reply within the time stated in the notice.

Whether a notice issued by your jurisdictional officer rather than the faceless centre is valid is unsettled. Several High Courts held such notices invalid, but the Finance Act 2026 added Section 147A, retrospective from 1 April 2021, to validate them. The Punjab and Haryana High Court struck that section down in September 2026, and on 18 September 2026 the Supreme Court stayed that ruling, on condition that the assessments in the cases before it do not proceed further, with the final hearing listed for 3 December 2026. Treat any notice as live, reply on time, and have a CA keep the jurisdiction objection on record.

31 March: end of FY. Last chance to file Section 119(2)(b) condonation for any FY ending in the past 5 Assessment Years. The 5-AY clock is rolling, every April, the oldest year drops out. ₹2 lakh of recoverable TDS becomes unclaimable if you miss the rolling deadline.

This is the month most CAs are too busy to take new NRI work, so plan February if you want to make the March cutoff.

Separate clock from the IT department's. Indian banks holding NRO/NRE accounts have to file FATCA reporting under the India-US Inter-Governmental Agreement and CRS reporting under OECD's framework.

Your bank asks for a self-certification when you open the account and when your details change, and many banks also run periodic refresh drives. If you ignore the prompt, the bank flags your account as non-compliant and tightens KYC. Worst case: NRO account freeze.

The self-certification is online for ICICI, HDFC, Axis. SBI still requires a paper form in some branches. Takes 10 minutes if your TIN, address, country of tax residency, and country of citizenship are all consistent across documents.

If you have multiple Indian bank accounts, expect several separate prompts, one per bank. They don't talk to each other.

Manual tracking in a calendar app works for one or two deadlines. By the time you're juggling a dozen across two countries, you'll miss something.

/tools/compliance-radar pulls your country, your account types, your past TRC issuance dates, and your last Form 10F file date from a 2-minute intake form. It then generates a personalised 12-month grid with hard deadlines and soft deadlines color-coded.

The radar emails or WhatsApps you 15 days before any hard deadline and 30 days before any soft one. We don't sell the data, we don't share it, we don't run ads off it. If you'd rather a CA handled these for you (Form 41 refile, TRC liaison, FATCA refresh), book a free CA appointment to discuss scope.

Upload your 26AS first if you want the recovery side handled alongside the forward calendar. Or book free CA appointment to see the radar live before you trust it with your inbox.

Q: I'm a US NRI. Does my IRS calendar matter for the Indian one?

A: They overlap on TRC. The IRS issues Form 6166 (the US TRC equivalent) only after your 1040 is on record for the year. So if you delay your US filing past 15 April or your extension past 15 October, your Indian TRC for the year lags. Plan the US filing around the Indian Form 41 (formerly Form 10F) refile, not the other way around.

Q: What happens if I miss Schedule FA on my ITR?

A: Only an ROR has to file Schedule FA. For an ROR, the Black Money Act allows a ₹10 lakh penalty for each year a foreign asset is left out. Since 1 October 2024 that penalty, and prosecution under Sections 49 and 50, do not apply where your foreign assets other than immovable property total ₹20 lakh or less. The duty to report every foreign asset in Schedule FA stays at any value, so don't skip it.

Q: My TRC is January 2026 but my Indian FY runs April 2026 to March 2027. Which applies?

A: A TRC covers only the period printed on it. A calendar-2026 TRC covers April to December 2026, so for January to March 2027 you need the next one. Expect your bank to ask for both, and give it the second as soon as it is issued.

Q: Can I just hire someone to handle all of these?

A: Yes. Our annual NRI compliance retainer covers Form 10F / Form 41 refile, FATCA refresh across up to 5 banks, TRC liaison if your foreign authority needs documents, ITR filing, Schedule FA disclosure, and Section 143(1) response if any. Book a free CA appointment to discuss scope.
