NRI Tax Calendar 2026 — Every Deadline, Due Date & Compliance Timeline for FY 2025-26

Missing a single tax deadline in India can cost an NRI thousands of rupees in interest, penalties, and unnecessary stress. When you are managing finances across two countries, across different time zones, and often without a local presence in India, a missed date is not just an inconvenience — it is a financial liability.

This is your definitive, month-by-month compliance calendar for FY 2025-26 (Assessment Year 2026-27). Bookmark it. Print it. Set reminders for every date listed below. This single reference will keep you penalty-free and fully compliant throughout the financial year and beyond.

Important Disclaimer: This calendar is based on the Income Tax Act, 1961 and prevailing rules as applicable for FY 2025-26. The government may extend specific deadlines via notification. Always verify dates against the latest CBDT circulars or consult a qualified chartered accountant before acting.

Why NRIs Need a Dedicated Tax Calendar

Resident Indians have their chartered accountants, employers, and bank branches reminding them of deadlines. NRIs rarely get that luxury. Banks abroad do not send advance tax reminders. Your US or UAE employer is not going to alert you about Indian TDS return dates. And the consequences of missing deadlines are identical whether you are sitting in Mumbai or Melbourne.

Here is what makes the NRI compliance timeline uniquely challenging:

• Advance tax obligations arise even on rental income, capital gains, and interest income that is not subject to adequate TDS.
• TDS on property sales requires the buyer to deposit tax within 30 days, but the NRI seller must verify compliance and claim credit.
• DTAA benefits require proactive submission of Tax Residency Certificates (TRC) and Form 10F — well before the income is earned.
• Form 67 for Foreign Tax Credit has a strict deadline that, if missed, can deny you relief from double taxation entirely.
• Section 197 certificates for lower or nil TDS must be obtained before the transaction, not after.

This calendar addresses every one of these scenarios.

The Complete Month-by-Month NRI Tax Calendar: FY 2025-26

April 2025 — Financial Year Begins

Key Dates:

Practical Tips for NRIs:

• Submit your Tax Residency Certificate (TRC) to Indian banks immediately. If you want DTAA benefits on interest income, FD interest, or any other payment, the bank needs your TRC and Form 10F on file before the first payment of the year. Submitting in April ensures the correct (lower) TDS rate is applied from day one.
• Review your residential status projections. Count your expected days in India for FY 2025-26. If you are likely to cross 182 days (or 120 days under the amended rules with Indian income exceeding Rs 15 lakh), your entire compliance framework changes.
• Apply for Section 197 certificate if needed. If you expect property rental income, plan to sell property, or have other income where TDS will be excessive relative to your actual liability, file Form 13 with the Assessing Officer early. Processing takes 30 days, so April applications ensure coverage from Q1 itself.
• Estimate your total Indian income for the year. Rental income, expected capital gains, interest income, dividend income — create a projection now. This determines whether you need to pay advance tax starting June.

May 2025 — Preparation Month

Key Dates:

Practical Tips for NRIs:

• Download and verify your Form 26AS and AIS (Annual Information Statement). Log in to the income tax portal and cross-check every TDS entry. Discrepancies found now can be corrected before the ITR filing rush.
• Gather all documents for your previous year's ITR. Bank statements, capital gains statements from brokers, Form 16 from Indian employers (if any), property rental receipts, and foreign income details.
• Calculate advance tax liability for Q1. If your projected tax liability for FY 2025-26 (after TDS) exceeds Rs 10,000, you are required to pay advance tax. The first installment is due June 15.

June 2025 — First Advance Tax Installment

Key Dates:

Practical Tips for NRIs:

• Pay advance tax online through the e-filing portal or authorized bank. NRIs can pay using Indian bank accounts or through specific international payment gateways linked to the tax portal. Use Challan ITNS 280 with the correct AY (2026-27) and PAN.
• Do not ignore this installment thinking TDS covers everything. If you have rental income without adequate TDS, capital gains from mutual funds or property, or interest income from NRO accounts where TDS was deducted at 30% but your actual rate is lower (after DTAA), your net liability may still require advance tax.
• Section 234C interest kicks in if you miss this date. Interest at 1% per month on the shortfall is charged for three months (from June to September). On a Rs 5 lakh shortfall, that is Rs 15,000 in avoidable interest.

Penalty for Missing June 15 Deadline: Interest under Section 234C at 1% per month on the shortfall amount (difference between 15% of assessed tax and tax actually paid) for 3 months.

July 2025 — ITR Filing and Q1 TDS Return

Key Dates:

Practical Tips for NRIs:

• This July 31 deadline is for the PREVIOUS year's return (AY 2025-26 / FY 2024-25). If you missed the original July 31, 2025 due date, you can still file a belated return until December 31, 2025 (see December section). But note that as of this date, the original deadline for AY 2025-26 has passed.
• Verify TDS credits in Form 26AS against your ITR. Mismatched TDS entries are the single most common reason for NRI ITR processing delays and incorrect refund calculations.
• If you have foreign income and paid tax abroad, prepare Form 67 for Foreign Tax Credit claim. Under Rule 128, Form 67 must be filed on or before the due date of filing the return of income. For AY 2026-27, this means on or before July 31, 2026 — but preparation should begin now.

---

August 2025 — Mid-Year Review

Key Dates:

Practical Tips for NRIs:

• Conduct a mid-year tax review. Revisit your income projections from April. Has rental income changed? Did you sell any assets? Are mutual fund dividends higher than expected? Adjust your advance tax estimate accordingly.
• If you sold property in Q1, verify that the buyer deposited TDS (Section 195). The buyer must deposit TDS within 30 days of deduction and file Form 27Q. Check your Form 26AS to confirm the credit appears.
• Consider tax-loss harvesting. If you hold equity mutual funds or listed shares with unrealized losses, selling and repurchasing (after accounting for the applicable holding period rules) before September can offset capital gains and reduce your advance tax burden.

September 2025 — Second Advance Tax Installment and Belated Return Deadline

Key Dates:

Practical Tips for NRIs:

• The September 15 installment is cumulative. If you paid Rs 15,000 in June (15% of Rs 1,00,000 estimated tax), you now need to pay Rs 30,000 more to reach Rs 45,000 (45% of Rs 1,00,000). The payment is the difference between 45% and what you have already paid.
• September 30 is your absolute last chance for AY 2025-26 belated returns. After this date, you cannot file a return for FY 2024-25 at all (unless the department specifically allows condonation of delay under Section 119(2)(b), which is discretionary and not guaranteed). A late fee of Rs 5,000 under Section 234F applies (Rs 1,000 if total income is below Rs 5 lakh).
• NRIs who missed claiming DTAA benefits or Foreign Tax Credit in their original return must file a revised return before December 31, 2025. But if you never filed at all, September 30 is the hard stop for belated filing.

Penalty for Missing September 15 Deadline: Interest under Section 234C at 1% per month on the shortfall (difference between 45% of assessed tax and advance tax actually paid) for 3 months.

Penalty for Missing September 30 Belated Return Deadline: You lose the right to file a return for AY 2025-26 entirely. Any refund due is forfeited unless you obtain condonation of delay. Carry-forward of losses (except house property loss) is permanently denied.

October 2025 — Q2 TDS Return and Planning

Key Dates:

Practical Tips for NRIs:

• If you sold a capital asset in this quarter, calculate long-term vs short-term capital gains now. This determines whether you need a larger advance tax payment in December.
• Start planning Section 54EC bond investments if you sold property. You have six months from the date of transfer to invest up to Rs 50 lakh in specified bonds (NHAI/REC) to claim exemption. If you sold in October, your deadline is April of the following year — but do not wait until the last week.
• Verify Q2 TDS credits in Form 26AS. Banks, tenants, and other deductors should have deposited TDS for Q2 by now.

---

November 2025 — Pre-Winter Compliance Check

Key Dates:

Practical Tips for NRIs:

• Review your advance tax position. With December 15 approaching, calculate your total tax liability based on actual income received through October. If your income is significantly higher than estimated, increase your December installment.
• If you are an NRI earning salary from an Indian employer, request your updated Form 12BA and computation sheet. This helps reconcile employer TDS with your overall liability.

---

December 2025 — Third Advance Tax Installment and Revised Return Deadline

Key Dates:

Practical Tips for NRIs:

• December 15 is the largest advance tax checkpoint. You need cumulative payments equal to 75% of your estimated total liability. For NRIs with lumpy income (like property sale capital gains), this installment often involves the biggest single payment.
• December 31 is the final opportunity to revise your AY 2025-26 return. If you discovered an error, forgot to claim a deduction, or received a corrected Form 16A, file the revised return before midnight on December 31. After this date, the original return (whether timely or belated) becomes final.
• DTAA benefit corrections must happen by December 31 if your original AY 2025-26 return had errors in treaty relief claims.

Penalty for Missing December 15 Deadline: Interest under Section 234C at 1% per month on the shortfall (difference between 75% of assessed tax and advance tax actually paid) for 3 months.

January 2026 — New Calendar Year, Final Quarter Begins

Key Dates:

Practical Tips for NRIs:

• Review your AIS (Annual Information Statement) on the income tax portal. By January, most high-value transactions from the first three quarters are reflected. Verify that the data matches your records.
• If you plan to invest in ELSS mutual funds or other Section 80C instruments for FY 2025-26, do it now. Do not wait until March when NAVs can be volatile and processing delays may push your investment past March 31.
• Plan your India visit dates carefully for January-March. Every day spent in India counts toward your residential status calculation. If you are close to the 182-day or 120-day threshold, consult a tax advisor before booking travel.

---

February 2026 — Pre-Closing Month

Key Dates:

Practical Tips for NRIs:

• Finalize your tax-saving investments. PPF contributions, NPS (if eligible), life insurance premiums, and health insurance premiums for Section 80D all need to be paid before March 31.
• If you have NRO account interest income, check if your bank has deducted TDS at the correct rate. If you submitted a TRC for DTAA benefits, verify the reduced rate was actually applied. Corrections take time, and March is too late to start.
• For NRIs who sold property earlier in the year and plan to claim Section 54 (reinvestment in residential property), confirm that the reinvestment is on track. You have two years from the date of sale to purchase, or three years to construct. If using the Capital Gains Account Scheme (CGAS), the deposit must happen before the ITR filing due date.

---

March 2026 — Financial Year Closes

Key Dates:

Practical Tips for NRIs:

• March 15 is the final advance tax installment. After this date, any unpaid tax attracts interest under Section 234B (for total shortfall exceeding 10% of assessed tax) and Section 234C (for installment-level shortfall).
• March 31 is the absolute last day for Section 54EC bond investments if your property sale was in the previous six months (October 2025 onwards). These bonds have limited availability — do not assume they will be available on March 31.
• Complete all ELSS, PPF, NPS, and insurance premium payments before March 31. Post-dated cheques and pending online transactions that clear after March 31 do not qualify for FY 2025-26 deductions.
• Collect rent receipts, donation receipts (Section 80G), and all supporting documents. You will need them when filing your ITR in the coming months.
• March 31 deposit of TDS by deductors for March payments. The due date for government deductors is March 31 itself; for non-government deductors, TDS deducted in March is due by April 30.

Penalty for Missing March 15 Deadline: Interest under Section 234C at 1% per month on the shortfall (difference between 100% of assessed tax and advance tax actually paid) for 1 month.

---

April-July 2026 — Post-Closing Compliance (AY 2026-27 Filing)

Key Dates:

Practical Tips for NRIs:

• Form 67 for claiming Foreign Tax Credit must be filed on or before the due date of the return. If you paid tax in the US, UK, UAE (on certain incomes), Canada, Australia, or any other treaty country, and want to claim credit against your Indian tax liability, Form 67 is mandatory. Missing the July 31, 2026 deadline for Form 67 can result in denial of FTC, leading to effective double taxation.
• Download your final Form 26AS and AIS for FY 2025-26 after May 31. By then, all four quarters of TDS returns should be filed, and your complete TDS credit picture will be available.
• Do not wait until July to start ITR preparation. Begin compiling income details, bank statements, capital gains statements, and foreign income documents from April itself.

---

TDS Return Filing Due Dates — FY 2025-26 (Complete Schedule)

This table is critical for NRIs who are also deductors (e.g., employers paying salary, or those making payments to contractors/professionals in India).

Note: Form 27Q is specifically for TDS on payments made to NRIs and foreign companies. If you are the payer (e.g., an Indian company you own making payments abroad), ensuring timely Form 27Q filing is critical to avoid penalties under Section 271H (Rs 10,000 to Rs 1,00,000).

---

Section 197 — Application Timing for Lower/Nil TDS Certificate

NRIs frequently suffer from excessive TDS deduction, particularly on:

• Property sale proceeds (TDS at 12.5% on the entire sale consideration, not just capital gains)
• Rental income (TDS at 30% under Section 195)
• Professional or consulting fees (TDS at 30%+)

When to apply: File Form 13 with your jurisdictional Assessing Officer at least 30-45 days before the expected transaction or payment. For property sales, apply as soon as you have a buyer and agreed sale price. For recurring income like rent, apply in April for the full year.

Application window: There is no fixed statutory deadline, but the certificate is valid only for the financial year in which it is issued. Apply early in the financial year for maximum benefit.

Interest Calculation Deep Dive: Sections 234A, 234B, and 234C

Section 234A — Interest for Late Filing

• Rate: 1% per month (or part of a month), simple interest
• Charged on: Outstanding tax liability (total tax minus advance tax and TDS already paid)
• Period: From the due date of the return (July 31) until the actual date of filing
• Example: If your tax liability is Rs 2,00,000, you paid Rs 1,50,000 as advance tax and TDS, and you file your return on October 15 (instead of July 31), you owe 1% x Rs 50,000 x 3 months = Rs 1,500

Section 234B — Interest for Default in Advance Tax

• Rate: 1% per month (or part of a month), simple interest
• Triggered when: Advance tax paid is less than 90% of the assessed tax liability
• Charged on: Difference between assessed tax and advance tax paid
• Period: From April 1 of the assessment year until the date of determination of income under Section 143(1) or the date of regular assessment
• Example: Assessed tax is Rs 3,00,000. Advance tax paid is Rs 2,00,000 (less than Rs 2,70,000, i.e., 90%). Interest on Rs 1,00,000 (Rs 3,00,000 minus Rs 2,00,000) at 1% per month from April 1 until assessment.

Section 234C — Interest for Deferment of Advance Tax

• Rate: 1% per month, simple interest
• Charged on: Shortfall in each installment
• Period: 3 months for each of the first three installments; 1 month for the fourth installment
• Special provision for capital gains/casual income: If the shortfall is due to capital gains or casual income arising after the installment due date, interest is waived if the entire shortfall is paid in the subsequent installment.

Special Dates NRIs Often Overlook

Capital Gains Account Scheme (CGAS) Deposit Deadline

If you sold property and want to claim Section 54 or 54F exemption but have not yet reinvested, deposit the unutilized amount in a CGAS account before the ITR filing due date (July 31, 2026 for FY 2025-26). Missing this means the exemption is denied.

Tax Audit Report Deadline (Section 44AB)

If you are an NRI with business income in India exceeding Rs 1 crore turnover (or Rs 10 crore under the presumptive scheme threshold) or professional income exceeding Rs 50 lakh, the tax audit report must be filed by October 31, 2026 for AY 2026-27. Your ITR due date also extends to October 31 in this case.

Advance Ruling Application

NRIs entering into significant transactions in India (mergers, acquisitions, large property deals) can apply for an Advance Ruling under Section 245Q before executing the transaction. There is no deadline per se, but the application must be made before the transaction to be effective.

12 Frequently Asked Questions (FAQs)

1. What happens if I miss the July 31 ITR filing deadline as an NRI?

You can file a belated return under Section 139(4) until December 31 of the assessment year. However, you will face a late filing fee of Rs 5,000 under Section 234F (Rs 1,000 if total income is below Rs 5 lakh), interest under Section 234A at 1% per month on unpaid tax, and you cannot carry forward certain losses (business loss, capital loss) from that year. House property loss carry-forward, however, is still permitted even with a belated return.

2. Is advance tax mandatory for NRIs?

Yes, if your estimated tax liability for the year (after subtracting TDS and TCS credits) exceeds Rs 10,000, you are required to pay advance tax in four installments. This applies regardless of your residential status. However, a senior citizen (60 years or older) who does not have income from business or profession is exempt from advance tax under Section 207.

3. Can I pay advance tax in one lump sum instead of four installments?

Yes, you can pay your entire estimated tax liability in the first installment itself (by June 15). There is no restriction on paying more than the minimum required in any installment. In fact, paying early avoids any risk of Section 234C interest. Many NRIs prefer to pay 100% by June 15 for simplicity.

4. What is the penalty if I miss the advance tax installment on June 15 but pay the full amount by September 15?

Interest under Section 234C is charged at 1% per month for 3 months on the shortfall for Q1. If 15% of your assessed tax is Rs 50,000 and you paid nothing by June 15, the interest would be 1% x Rs 50,000 x 3 months = Rs 1,500. If you pay the cumulative 45% (or more) by September 15, no further 234C interest arises for Q2.

5. When exactly must I file Form 67 for Foreign Tax Credit?

Form 67 must be filed on or before the due date of filing the return of income. For AY 2026-27 (FY 2025-26), this is typically July 31, 2026 for individuals not subject to audit. The form must be filed electronically on the income tax portal along with supporting documents (foreign tax payment proof, tax return copy from the other country, etc.).

6. What is the TRC, and when should I submit it to my Indian bank?

A Tax Residency Certificate (TRC) is issued by the tax authority of your country of residence, confirming that you are a tax resident there. You need it to claim benefits under India's Double Taxation Avoidance Agreements (DTAA) — typically a reduced TDS rate on interest, dividends, or other income. Submit it to your Indian bank and other payers at the beginning of the financial year (April) along with Form 10F. Without it, TDS will be deducted at the standard domestic rate (usually 30% or higher for NRIs).

7. Can I file a revised return if I discover an error after filing my ITR?

Yes, under Section 139(5), you can file a revised return before December 31 of the relevant assessment year or before the completion of assessment, whichever is earlier. For AY 2026-27, the revised return deadline would be December 31, 2026. For the previous AY 2025-26, the deadline was December 31, 2025.

8. What is the Section 197 lower TDS certificate, and how long does it take?

Section 197 allows you to apply (via Form 13) to your Assessing Officer for a certificate authorizing lower or nil TDS deduction. This is crucial for NRIs selling property (where TDS is on the full sale amount, not just capital gains) or receiving large payments subject to withholding. Processing typically takes 30 days from the date of application. The certificate is valid only for the financial year specified and for the specific transaction/payer mentioned.

9. What if I miss the September 30 belated return deadline for a previous assessment year?

You lose the right to file a return for that year entirely. Any tax refund due to you is forfeited. The only recourse is to apply for condonation of delay under Section 119(2)(b) to the Principal Commissioner or Commissioner of Income Tax. This is a discretionary power, and approval is not guaranteed. It is granted only in cases of genuine hardship and where the delay is for reasons beyond your control.

10. Are there different ITR due dates for NRIs with business income requiring audit?

Yes. If your accounts are subject to tax audit under Section 44AB (business turnover exceeding the prescribed threshold), your ITR due date extends to October 31 of the assessment year. For AY 2026-27, that would be October 31, 2026. If transfer pricing provisions apply (Section 92E), the due date extends further to November 30, 2026.

11. How does capital gains advance tax work if I sell property in January 2026?

If a capital gain arises after the due date of an advance tax installment, you are not charged interest under Section 234C for installments that were already due. You simply include the entire capital gains tax in the next installment. If property is sold in January 2026 (after the December 15 installment), you pay the capital gains tax along with your March 15 installment. If the sale happens after March 15, pay the tax before March 31 to minimize Section 234B interest.

12. What is the last date to invest in Section 54EC bonds for a property sold in October 2025?

You have six months from the date of transfer. If you sold property on October 15, 2025, you have until April 14, 2026 to invest up to Rs 50 lakh in specified 54EC bonds (NHAI Capital Gains Bond, REC Capital Gains Bond). Do not wait until the last day — these bonds have limited issuance windows and may not be available on your exact deadline.

Do Not Navigate This Alone

The NRI tax calendar is dense, unforgiving, and full of deadlines that interact with each other in complex ways. A missed advance tax installment compounds into Section 234B and 234C interest. A missed Form 67 deadline turns your DTAA benefit into double taxation. A missed belated return date erases your right to claim a refund entirely.
