Missing the ITR filing deadline does not mean you have lost the opportunity to stay compliant. While the original due date has passed, the Income Tax Department (ITD) still allows most crypto investors to file a belated return under Section 139(4) of the Income Tax Act, 1961, and regularise their tax position. The key is to act quickly because delaying further only increases the cost of non-compliance.
Besides incurring the late filing fee, you will also have to pay the interest that starts accruing on any unpaid tax from the day after the original deadline. Since crypto gains are already taxed at a flat 30%, every additional month without filing increases the overall liability and makes the final payable amount even higher.
Fortunately, the belated return window under Section 139(4) of the Income Tax Act remains open until 31st December 2026. This means you can still file your return and continue to claim the TDS deducted by exchanges under Section 194S through your Form 26AS. In this guide, you’ll learn who can still file a belated return, the costs involved, the correct ITR form to use, and the steps to complete your filing for FY 2025–26.

What Happens After You Miss the Crypto ITR Deadline in India?
Missing the ITR filing deadline is not the end of the road, but it does trigger additional tax and compliance obligations. For crypto investors, knowing what happens after the due date and the options still available can make the difference between resolving the issue early and facing higher costs later.
Your Tax Liability Does Not Disappear but Grows
Missing the deadline does not pause or cancel your tax obligation. The 30% flat tax on VDA disposals under Section 115BBH remains due from the original filing date. What changes is that the total amount owed begins increasing from that point forward, through interest charges that compound month by month until the return is filed.
Interest Starts Accruing From the Day After Your Deadline
You are charged interest on a monthly basis on unpaid tax from the day after your original due date. That rate applies to every month, or part of a month, that passes without a filed return. The longer the gap between the original deadline and the actual filing date, the larger the interest component will be.
The ITD Already Sees Your Crypto Activity Through AIS
Every eligible crypto transfer you made during FY 2025-26 generated a 1% TDS deduction under Section 194S. That data was reported by exchanges to the ITD and is now reflected in your Annual Information Statement (AIS). Your transactions are already visible, what is missing is the corresponding return that accounts for them.
Non-Filing Triggers a Higher Risk than Late Filing
When the ITD’s AIS shows crypto income with no matching return, it creates a discrepancy that draws scrutiny. That discrepancy is the primary trigger for a reassessment notice under Section 148A. A late return with interest paid is a far more defensible position than an absent return against a visible transaction record.
The good news is that you still have a way to fix the situation. By filing a belated return, you can regularise your tax filing and stop additional interest from building up on unpaid tax before the consequences become more serious.

What is a Belated Return?
A belated return is an income tax return filed after you have missed the original due date for that particular ITR form. It can be filed under Section 139(4) of the Income Tax Act, 1961, and allows any taxpayer who missed the original filing deadline to still report their income, pay applicable taxes, and comply with the law.
The belated return must be filed three months prior to the end of the relevant assessment year, or before the completion of assessment, whichever is earlier. For FY 2025-26 (AY 2026-27), the last date to file a belated return is 31st December 2026.
ITR Filing Deadlines for Crypto Investors for FY 2025-26 (AY 2026-27)
Before filing, it helps to know exactly where you stand on the deadline calendar. The original due date depends on which ITR form applies to you, and whether your trading activity crosses the audit threshold.
Taxpayer Category | Due Date |
ITR-2 | 31st July 2026 |
ITR-3 (Non-Audit Cases) | 31st August 2026 |
ITR-3 (Audit Cases) | 31st October 2026 |
Belated Return | 31st December 2026 |
Updated Return or ITR-U | 31st March 2030 |
Which ITR Form Should Crypto Investors Use for FY 2025-26?
The correct ITR form does not change simply because you are filing late. What changes is the filing status selected on the portal: Section 139(4) instead of Section 139(1). The form itself, and every schedule within it, is filled identically to an on-time return.
Who Must File ITR-2 in India?
Here’s a list of crypto users who must file ITR-2 in India:
- Salaried individuals or pensioners who buy, hold, and later sell or swap crypto
- Active spot traders disposing of crypto frequently, across one or multiple exchanges
- Investors using leverage or margin on spot positions, without trading Futures or Options
- Algorithmic or bot traders executing spot trades, regardless of volume
- Casual miners without a dedicated, organised mining setup
- Recipients of staking rewards, airdrops, or hard forks who disposed of those tokens
- Gift recipients who received and later disposed of crypto
- Investors holding crypto on foreign exchanges such as Binance or Bybit (Schedule FA also required)
Who Must File ITR-3 in India?
Here’s a list of crypto users who must file ITR-3 in India:
- Operators of large-scale, commercial mining setups with dedicated rigs and hardware
- Traders of crypto Futures and Options contracts, even a single contract
- Salaried employees who also run a business mining setup or trade crypto F&O
- Freelancers receiving crypto as payment for services rendered
- Operators of a crypto consultancy or advisory business
What Penalties Apply When Filing a Belated Crypto ITR?
Three separate charges apply when a crypto investor files after the original deadline. Knowing the exact figure for each one removes the uncertainty that keeps many investors from acting sooner.
Late Filing Fee, Section 234F
The flat late filing fee is INR 5,000 for taxpayers whose total income exceeds INR 5 lakh. For income between the basic exemption limit and INR 5 lakh, the fee is INR 1,000. Below the basic exemption limit, no fee applies at all.
For a crypto investor whose total income is well above INR 5 lakh, INR 5,000 is a fixed, one-time charge. It does not compound. It does not increase with time. The fee is identical whether you file on 1st August or 30th December 2026.
Interest on Outstanding Tax, Section 234A
This is where delay becomes genuinely expensive. Interest under Section 234A accrues at 1% per month, or part of a month, on the tax amount that remains unpaid after 31st July 2026. Unlike the late fee, this charge grows with every passing month.
So, a crypto investor with an unpaid tax liability of INR 3,00,000 will accumulate INR 3,000 in additional interest per month. By December 2026, five months after the original deadline, the interest amount will grow to INR 15,000, and will be added to a bill that already carries a flat 30% tax rate under Section 115BBH.
Interest on Advance Tax Shortfall, Sections 234B and 234C
Section 234B applies when an investor did not pay advance tax of at least 90% of their total liability during FY 2025-26. Interest accrues at 1% per month from 1st April 2026 to the date of actual filing. Section 234C applies separately where quarterly advance tax instalments, due in June, September, December, and March, were missed or underpaid during the year.
Both charges are calculated on the shortfall amount, not the full liability. An investor who paid some advance tax but fell short of the 90% threshold will owe proportionate interest under these sections, not interest on the entire bill.
How to File a Belated Crypto ITR for FY 2025-26?
With the deadlines and costs clear, the remaining task is the filing itself. The process on the income tax portal mirrors an original return in every step, the only distinction is the section selected at the filing stage.
Step 1: Gather Your Records
Download exchange statements from every platform used during FY 2025-26, CoinDCX, WazirX, Binance, Bybit, and any other active platform. For each VDA disposal, you need the acquisition date, transfer date, cost of acquisition in INR, and sale consideration in INR. Download your AIS and Form 26AS from incometax.gov.in to verify TDS entries before you begin.
Step 2: Calculate Your Schedule VDA Entries
For each disposal, the taxable gain equals sale consideration minus cost of acquisition. No additional deductions are permitted under Section 115BBH, not brokerage, gas fees, or platform charges. Each disposal is a separate Schedule VDA entry. Where crypto was received as income first, salary, freelance payment, or staking reward, the FMV at the date of receipt is the cost of acquisition for that token.
Step 3: Log In and Select Section 139(4)
Visit the Income Tax portal and log in using your PAN credentials. Select the ITR form applicable to your activity: ITR-2 for passive investors and spot traders, ITR-3 for F&O traders, freelancers, and business income earners. Under the filing status field, select Section 139(4), Belated Return. Selecting Section 139(1) here would be incorrect for a return filed after the original deadline.
Step 4: Fill Schedule VDA and Reconcile Against AIS
Enter each disposal event individually in Schedule VDA with the acquisition date, transfer date, cost, and gain. Cross-check the gross transaction values you are reporting against the figures visible in your AIS. Where the AIS reflects a higher gross volume than your declared net gain, which is common because exchanges report total trade value, not profit, prepare a brief reconciliation note before submission.
Step 5: Calculate Total Liability and Pay Self-Assessment Tax
Before submitting, calculate the complete liability:
- 30% tax on your taxable Schedule VDA gains
- Add 4% health and education cess to the tax payable
- Subtract the TDS credits reflected in your Form 26AS, including deductions under Section 194S
- Add interest under Section 234A from 1st August 2026 until the date you file your return
- Include the applicable late filing fee under Section 234F before arriving at your final tax liability
Pay the balance as self-assessment tax through the portal. Keep the challan number, it is a required field in the return itself.
Step 6: Submit and e-Verify Within 30 Days
After submission, e-verify the return within 30 days using Aadhaar OTP, net banking, or a digital signature certificate. An unverified return is treated as invalid under the Income Tax Act, the equivalent of not having filed. Once verified, the ITD processes the return, applies TDS credits, and initiates any applicable refund to the pre-validated bank account linked to your PAN.
Important to Note:
If you also hold equity shares, mutual funds, or other non-crypto assets where you incurred losses this year, those losses cannot be carried forward when filing a belated return. Section 139(3) of the Income Tax Act requires loss returns to be filed within the original deadline. Remember, VDA losses under Section 115BBH are already barred from carry-forward regardless of when you file, so the belated return creates no additional restriction specific to crypto.

What If You Miss 31st December 2026 as Well?
If you have missed the original deadline then, filing by 31st December 2026 is the recommended action. However, for investors dealing with earlier financial years or those who miss this window too, the Income Tax Act provides a further option, with important restrictions. Here’s what can be done in such scenarios:
File an ITR-U Under Section 139(8A)
An updated return, filed using ITR-U under Section 139(8A) of the Income Tax Act, allows taxpayers to correct errors or omissions in previously filed returns, or file for a year where no return was submitted at all. Following Budget 2025, the ITR-U window has been extended to 48 months from the end of the relevant assessment year.
Note: ITR-U is available regardless of whether you filed an original, belated, or revised return for that year. However, it cannot be used to claim a refund or reduce an existing tax liability.
Whether you are filing a belated return before 31st December 2026 or an updated return through ITR-U, accurate transaction records across every wallet and exchange are the foundation of a clean filing. Without them, neither option can be completed correctly. KoinX automatically imports data from 800+ exchanges, calculates your Schedule VDA entries, and ensures your reported selling figures match what the ITD already holds in your AIS, so your records are ready before the deadline, not after.
Penalties Charged When Filing and ITR-U
As covered above, since 1st April 2025, the ITR-U window has been extended to 48 months from the end of the relevant assessment year. However, the additional tax penalty increases the longer you wait. Filing earlier within that window significantly reduces the extra cost. Here is how much penalty you must pay if you are filing ITR-U:
ITR-U Filed Within | Additional Tax |
12 months from the end of the relevant AY | 25% of additional tax (tax + interest) |
24 months from the end of the relevant AY | 50% of additional tax (tax + interest) |
36 months from the end of the relevant AY | 60% of additional tax (tax + interest) |
48 months from the end of the relevant AY | 70% of additional tax (tax + interest) |
Condonation of Delay Under Section 119(2)(b)
Where genuine hardship prevented timely filing, a taxpayer may submit a condonation request on the e-filing portal under Section 119(2)(b). An ITD officer reviews the request and may allow late filing beyond the December 31st deadline. Remember, approval is entirely at the officer’s discretion. Submitting the request does not constitute a valid return until the officer accepts it and the return is subsequently filed.
Warning:
A taxpayer who wilfully fails to file a return risks prosecution under Section 276CC of the Income Tax Act, 1961. As amended by Finance Act 2026, where the tax evaded exceeds INR 50 lakh, the provision permits simple imprisonment of up to 2 years, or a fine, or both. Where the evaded amount is between INR 10 lakh and INR 50 lakh, imprisonment extends up to 6 months. In all other cases, a fine applies. With crypto TDS data, exchange SFT reports, and AIS transaction records already visible to the ITD, establishing taxable income requires far less investigation than most investors assume.
Whether you are filing a belated return before 31st December 2026 or an updated return through ITR-U, accurate transaction records across every wallet and exchange are the foundation of a clean filing. Without them, neither option can be completed correctly. KoinX automatically imports data from 800+ exchanges, calculates your Schedule VDA entries, and ensures your reported selling figures match what the ITD already holds in your AIS, so your records are ready before the deadline, not after.
How KoinX Can Help Crypto Investors File a Belated Return?
A belated return or an ITR-U filing for crypto income is not simply a matter of entering one figure in one field. Both require accurate Schedule VDA entries for every disposal across every platform, TDS reconciliation against Form 26AS, and AIS cross-checks before submission. When transactions span multiple exchanges, financial years, and wallet types, manual tracking can create the very mismatches that trigger ITD scrutiny, whether you are filing under Section 139(4) or Section 139(8A).
KoinX is a global crypto tax platform trusted by over 1.5 million users across 100+ countries, with 800+ exchange and wallet integrations. For Indian investors filing a belated return or an updated return, it generates ITR-ready Schedule VDA reports for both ITR-2 and ITR-3, reconciles TDS credits against Form 26AS, and ensures every figure declared selling price matches what the ITD already holds in the AIS, regardless of which filing route applies to your situation.
ITR-Ready Schedule VDA Reports for ITR-2 and ITR-3
KoinX generates Schedule VDA reports formatted for both ITR-2 and ITR-3, with each disposal listed individually as the ITD requires. Cost of acquisition, sale consideration, and gain are computed per transaction using the correct FMV methodology. The output transfers directly into the ITR form without manual recalculation.
Auto-Import from 800+ Exchanges and Wallets
KoinX connects to 800+ exchanges and wallets, including CoinDCX, WazirX, Binance, Bybit, Coinbase, and ZebPay, via API or CSV upload. Transaction data is imported, classified, and consolidated into a single tax computation. For investors active across multiple platforms, this eliminates the manual effort of compiling records exchange by exchange before filing.
In-App Access to Crypto Tax Experts
For investors uncertain about which ITR form applies, how to handle foreign exchange holdings under Schedule FA, or how to treat a specific transaction type, KoinX provides direct in-app access to an India-based crypto tax expert team with its bundled plan. Personalised guidance is available within the platform, no separate consultation required.
Every month without a filed return adds to a liability that was already significant. Therefore, generate your ITR-ready crypto tax report on KoinX and file with figures the ITD already expects to see.
Conclusion
Missing the ITR filing deadline does not limit your options, it changes them. The belated return window under Section 139(4) remains available, your TDS credits are still claimable, and the cost of filing late is defined and capped. What grows with every passing month is the interest on unpaid tax. Filing sooner, with accurate records and correctly filled schedules, is always the better route.
KoinX generates ITR-ready Schedule VDA reports, imports data from 800+ exchanges and wallets, and connects you to India-based crypto tax experts, so your belated return is filed accurately, with figures the ITD already expects to see.
Frequently Asked Questions
Will I Lose My TDS Refund If I File a Belated Crypto Return?
No. TDS deducted by exchanges under Section 194S is reflected in your Form 26AS regardless of when you file. A belated return filed before 31st December 2026 allows you to claim those credits fully against your tax liability. If the credits exceed the tax payable, the surplus is processed as a normal refund after the return is verified.
I Have Gains from Both Crypto and Equity This Year. Does Filing Late Affect Both Differently?
Yes. Under Section 115BBH, VDA losses cannot be carried forward regardless of when you file; the belated return creates no additional restriction for crypto specifically. However, equity capital gains losses and business losses from other asset classes cannot be carried forward if you miss the original deadline. Those losses are governed by Section 139(3), which requires filing within the original due date to preserve carry-forward rights.
I Did Not Pay any Advance Tax on My Crypto Gains. What Interest Do I Now Owe?
Two interest sections apply. Section 234B charges 1% per month on the shortfall between what you paid and 90% of your total tax liability, from 1st April 2026 to your filing date. Section 234C applies to each quarterly instalment that was missed or underpaid during FY 2025-26. Both are calculated on the shortfall amount, not the full tax figure.
I Traded on Both Binance and CoinDCX. Do I Need to Reconcile Both Against My AIS Before Filing?
Yes. The ITD’s AIS consolidates transaction information reported by crypto exchanges and other reporting entities. This includes data received from domestic platforms through SFT reporting and details related to foreign crypto holdings or transactions that may be available through other reporting mechanisms. Every disposal across every platform must appear in Schedule VDA. Cross-checking the gross figures in your AIS against your declared entries before filing is the most effective way to avoid a mismatch notice after submission.
What Happens If I Miss the 31st December Belated Return Deadline Entirely?
If you miss 31st December 2026, the belated return window under Section 139(4) closes. The remaining option is an updated return under Section 139(8A), ITR-U, which is now available for 48 months from the end of AY 2026-27 under Finance Act 2025. However, ITR-U cannot be used to claim a refund or reduce your tax liability. It is a compliance filing and not a refund mechanism.
The ITD Sent Me an AIS Mismatch Notification But I Have Not Filed Yet. How Urgent is This?
Quite urgent. An AIS mismatch notification means the ITD has flagged a discrepancy between what your exchanges reported and what your tax record shows. If ignored, this can escalate to a reassessment notice under Section 148A. The correct response is to file your belated return under Section 139(4) immediately, ensuring your Schedule VDA entries reconcile with the figures the ITD has already flagged in the notification.
I Filed My Original Return But Forgot to Include My Crypto Gains. What Do I Do?
If you already filed your return before the original deadline but omitted your crypto gains, the applicable option is a revised return under Section 139(5), not a belated return. The revised return deadline for FY 2025-26 is 31st March 2027. File the revision with the correct Schedule VDA entries and pay any additional tax, interest, and applicable penalty before submitting.
