According to data from the Ministry of Finance, the Income Tax Department collected INR 511.83 crore in crypto TDS in FY 2024-25 alone, implying trading volumes of over INR 51,000 crore. Yet a large share of those traders likely paid their entire tax only at the time of filing, unaware that interest had already begun accruing from the very first quarter of the financial year.
Advance tax is not optional for active crypto investors. If your estimated tax liability after TDS credits exceeds INR 10,000, you are required to pay in quarterly instalments, regardless of whether you traded throughout the year or made a single sale during a December bull run.
Missing these instalments means interest starts building well before you file your return, but getting it right is simpler than most traders assume. Therefore this guide walks you through every due date, calculation step, and payment method for FY 2025-26 (AY 2026-27), so you know what to pay and when.
Key Takeaways
- Advance tax applies when estimated tax liability after TDS exceeds INR 10,000; crypto gains taxed at 30% under Section 115BBH cross this threshold quickly.
- The advance tax must be paid in four instalments that are due on 15th June, 15th September, 15th December, and 15th March of the financial year.
- Missing or underpaying any instalment triggers 1% monthly interest under Section 234C on the quarterly shortfall.
- Failing to pay at least 90% of total tax by 31st March triggers additional 1% monthly interest under Section 234B from 1st April onwards.
- TDS deducted by Indian exchanges under Section 194S reduces your advance tax liability, but must be factored into each quarterly calculation.
- Crypto traders falling under the purview of Section 44AD must pay 100% advance tax in a single instalment by 15th March.
- FY 2025-26 advance tax defaults are governed by the Income Tax Act, 1961.
Understanding Advance Taxes in India
As per Section 208, advance tax is income tax paid in the same financial year the income is earned. The government considers it a “Pay-As-You-Earn” system. This means instead of settling your full tax bill in July, you pay it in four instalment.
Neither it is a new taxation, nor a penalty. It is the same 30% tax on crypto gains under Section 115BBH, spread across the year. Let’s understand it better:
Why the INR 10,000 Threshold Matters for Crypto Investors?
At a flat 30% tax rate plus 4% Health and Education Cess, an effective rate of 31.2%, a crypto gain of just INR 32,100 is enough to trigger the advance tax obligation. Equity investors often need much larger gains before crossing this line. Crypto investors cross it faster, and many do not realise it until they file.
Does TDS Already Deducted Count Towards Advance Tax?
Yes, but it does not eliminate the obligation. Indian exchanges deduct 1% TDS under Section 194S on every qualifying disposal. This credit is subtracted from your estimated total tax liability. If the residual amount still exceeds INR 10,000, advance tax will be due on the balance.
Who Needs to Pay Advance Tax on Crypto in India?
Not every crypto investor has the same advance tax profile. The obligation depends on how often you trade, whether your employer already deducts TDS on other income, and whether you use a presumptive taxation scheme. This section covers each scenario so you can identify where you stand:
Frequent Crypto Traders
Traders who book gains regularly across multiple exchanges accumulate tax liability throughout the year. Every disposal event adds to the running total. Waiting until March to pay the full amount exposes traders to Section 234C interest on every missed quarterly instalment, going back as far as June.
Moreover, each missed instalment’s interest runs for 3 months from that due date, meaning a June shortfall accumulates interest right through to the December period, this applies equally to crypto gains taxed as VDA income.
Occasional Investors Who Sold Once
A passive investor who held crypto for months and sold during a market rally can also pay advance tax. If the resulting gain produces a tax liability above INR 10,000 after TDS, the upcoming quarterly deadlines apply. The December and March instalment are the most relevant for gains realised in Q3 or Q4.
However, many crypto investors assume that they are only liable to pay tax during ITR filing. That assumption is incorrect, and the interest under Sections 234B and 234C can apply.
Salaried Employees With Crypto Gains
An employer deducts TDS under Section 192 on salary only. Crypto gains are a separate income stream entirely. The 1% TDS deducted by exchanges on crypto transactions is also separate. Both are credited against your total liability, but if the residual tax on crypto gains alone exceeds INR 10,000, advance tax applies regardless of salary TDS.
Traders Under Section 44AD
Taxpayers who declare crypto trading income under the Section 44AD presumptive scheme are exempt from the four-instalment schedule. They pay 100% of advance tax in a single instalment by 15th March. This simplifies advance tax compliance, but eligibility under Section 44AD and its interaction with Section 115BBH must be checked before using this option.
What are the Advance Tax Due Dates for Crypto Gains in FY 2025-26?
The advance tax schedule for FY 2025-26 runs across four deadlines. Each deadline requires a minimum cumulative percentage of your estimated annual tax liability, not just the portion for that quarter. Missing a deadline does not erase the obligation; it adds interest to the shortfall. So, here’s the deadline to file advance taxes in India:
Instalment | Due Date | Minimum Cumulative Tax to Be Paid |
1st Instalment | 15th June 2025 | At least 15% of estimated annual tax liability |
2nd Instalment | 15th September 2025 | At least 45% of estimated annual tax liability |
3rd Instalment | 15th December 2025 | At least 75% of estimated annual tax liability |
4th Instalment | 15th March 2026 | 100% of estimated annual tax liability |
Presumptive (Section 44AD) | 15th March 2026 | 100% in a single payment |
The Percentages are Cumulative and Not Per Quarter
This is where most taxpayers make an error. By 15th September, the total advance tax paid to date must equal at least 45% of the full year estimate, not 45% of what was left after June. If nothing was paid in June, the September payment must cover 45% in full.
Why December and March Matter Most for Crypto Investors?
Crypto market rallies tend to concentrate in Q3 and Q4, October through March. An investor who had zero gains in June and September but sold during a November price surge must account for a larger December instalment to avoid Section 234C interest on the cumulative shortfall. The later the gains arrive, the more important it is to recalculate promptly.
What Happens After 15th March?
Section 234C stops applying after 31st March. However, if at least 90% of the total tax liability has not been paid by that date, Section 234B begins from 1st April. It applies until the remaining tax is actually paid, whether at ITR filing or later. The two provisions cover different periods and are calculated independently.
How to Calculate Advance Tax on Crypto Gains?
Calculating advance tax on crypto gains involves five steps. The process is the same at each quarterly deadline, you update your estimate with actual gains, apply the tax rate, subtract TDS credits already accumulated, and pay the balance due for that instalment. Here is how you can calculate your crypto gain advance tax:
Step 1: Estimate Your Crypto Gains
Add up all disposal gains realised so far in the financial year. Use the First-In-First-Out (FIFO) method to assign cost of acquisition to each disposal. Section 115BBH does not permit loss set-off, so every gain is taxable in full. The estimate does not need to be exact, as it is revised at each quarterly deadline.
Estimated Gain = Sale Price − Cost of Acquisition (FIFO)
Step 2: Calculate the Tax and Cess
Apply 30% to the total estimated gain. Then, add 4% health and education cess on the tax amount. The effective rate works out to 31.2% of the total gain.
Tax on Gain = Estimated Gain × 30%
Cess = Tax on Gain × 4%
Total Tax Liability = Tax on Gain + Cess
Step 3: Subtract TDS Already Deducted
Open your Annual Information Statement (AIS) or Form 26AS and check the TDS deducted by exchanges under Section 194S on all disposals completed to date. Subtract the total TDS credit from the tax figure calculated in Step 2. The resulting number is your residual advance tax liability. If it exceeds INR 10,000, proceed to Step 4. Otherwise, you’re in the clear, at least, this quarter.
Residual Advance Tax Liability = Total Tax Liability − TDS Deducted to Date
Step 4: Apply the Instalment Percentage
Multiply the residual liability by the cumulative percentage due at the approaching deadline. Then, subtract any advance tax already paid in earlier instalment. The result is the amount due for the current quarter.
Amount Due This Quarter = (Residual Liability × Cumulative %) − Advance Tax Already Paid
For example, if the residual liability is INR 1,00,000 and the September deadline requires 45% cumulative, the total due to date is INR 45,000. If INR 15,000 was paid in June, the September payment is INR 30,000.
Step 5: Revise at Each Quarter
Crypto markets move sharply between quarters. So, do not forget to revise your annual gain estimate upward or downward at each deadline based on actual disposals to date.
Revised Residual Liability = Revised Total Tax − Updated TDS Credits − Advance Tax Already Paid
However, do not worry if you end up overpaying since it generates a refund at ITR filing, and no interest accrues on overpayment. But underpaying generates Section 234C interest on the shortfall for that period.
Example
A Reddit user named BLaDeizOP posted a question that captures exactly what most crypto investors discover too late. They had been selling crypto at a profit every month since the start of the financial year and assumed the only obligation was filing an ITR at year-end. When they learned about advance tax penalties, they had four questions: what advance tax is, how to pay it, what the penalty is for missing it, and whether monthly sellers must pay every month or quarterly.
The answer to that last question is quarterly, not monthly. The example below uses BLaDeizOP’s scenario to show how advance tax works for a monthly crypto seller in FY 2025-26.
Assumptions
BLaDeizOP sells ETH once every month throughout FY 2025-26. The average price of ETH in 2025 is approximately INR 2,27,000 per token. Each monthly sale generates a gain of INR 30,000 after deducting cost of acquisition. No surcharge applies. TDS at 1% is deducted by the Indian exchange on each disposal.
Parameter | Value |
Token | Ethereum (ETH) |
Average ETH price in 2025 | INR 2,27,000 per token |
Monthly gain per disposal | INR 30,000 |
Tax rate | 30% plus 4% cess = 31.2% effective |
TDS rate (Section 194S) | 1% of transaction value per disposal |
Estimated transaction value per disposal (Quarterly) | INR 90,000 (approximate, based on partial ETH sold) |
TDS per disposal | INR 900 |
Annual gain (12 months) | INR 3,60,000 |
Annual TDS (12 months) | INR 10,800 |
Quarter 1: 15th June 2025 (April, May, June)
Post-dated vouchers prepared after the notice arrives carry very little weight. Chat screenshots from Binance P2P, without government-issued identification of the counterparty, have been specifically rejected in Section 68 crypto cases.
Oral explanations without corroborating documents are treated as unsatisfactory by default. Where books of account were not maintained, the AO is not even required to call for explanations before making an addition.
Quarter 2: 15th September 2025 (July, August, September)
Six disposals completed. Cumulative gain: INR 1,80,000.
Revised Annual Gain Estimate | INR 3,60,000 (on track) |
Total Tax Liability (31.2%) | INR 1,12,320 |
TDS Deducted to Date | INR 5,400 (6 months × INR 900) |
Residual Liability | INR 1,06,920 |
45% Cumulative Due | INR 48,114 |
Advance Tax Already Paid (June) | INR 16,443 |
Amount Payable by 15th September | INR 31,671 |
Quarter 3: 15th December 2025 (October, November, December)
Nine disposals completed. Cumulative gain: INR 2,70,000.
Revised Annual Gain Estimate | INR 3,60,000 (on track) |
Total Tax Liability (31.2%) | INR 1,12,320 |
TDS Deducted to Date | INR 8,100 (9 months × INR 900) |
Residual Liability | INR 1,04,220 |
75% Cumulative Due | INR 78,165 |
Advance Tax Already Paid (June + September) | INR 48,114 |
Amount Payable by 15th December | INR 30,051 |
Quarter 4: 15th March 2026 (January, February, March)
Twelve disposals completed. Final actual gain: INR 3,60,000.
Final Annual Gain | INR 3,60,000 |
Total Tax Liability (31.2%) | INR 1,12,320 |
TDS Deducted to Date | INR 10,800 (12 months × INR 900) |
Residual Liability | INR 1,01,520 |
100% Due | INR 1,01,520 |
Advance Tax Already Paid (Q1 + Q2 + Q3) | INR 78,165 |
Amount Payable by 15th March | INR 23,355 |
Final Position at Filing
Total Advance Tax Paid | INR 1,01,520 |
Total TDS Credited | INR 10,800 |
Total Tax Settled | INR 1,12,320 |
Self-Assessment Tax Due at Filing | INR 0 |
The lesson: Advance tax is not settled at ITR filing. If your running tax liability after TDS exceeds INR 10,000, the quarterly clock starts from 15th June, regardless of how often you sell.
What Happens If You Miss or Underpay Advance Tax on Crypto?
Missing an advance tax instalment does not go unnoticed. The Income Tax Department applies interest automatically, and no notice or separate assessment is required for this. Two provisions operate across different time periods, and both can apply to the same taxpayer in the same financial year:
Section 234C: Interest on Late Quarterly Instalments
Section 234C applies when the cumulative advance tax paid by a quarterly deadline falls below the required minimum percentage.
Interest at 1% per month is charged on the shortfall for a fixed period, 3 months for the June, September, and December instalment, and one month for the March instalment. The interest is calculated on the deficit amount, not the full liability.
Note: Section 234C provides one limited relief. If a gain arises from capital assets, lotteries, or similar one-time income during the last quarter of the financial year, and the income was not reasonably estimable earlier, the interest does not apply to the shortfall on that specific gain. The full tax on that gain must still be paid by 15th March. |
Section 234B: Interest for Falling Below the 90% Threshold
Section 234B applies from 1st April if the total advance tax paid during the financial year is less than 90% of the assessed tax liability.
Interest accrues at 1% per month on the shortfall, from 1st April until the date the remaining tax is paid. For a trader who filed the ITR in July and settled the balance then, Section 234B interest runs for three full months.
Can Both Sections Apply at the Same Time?
Yes. A trader who missed the June and September instalment attracts Section 234C interest for those quarters. If that same trader also paid less than 90% of total liability by 31st March, Section 234B applies from 1st April on top. The two charges are calculated independently and added together in the final tax computation.
How to Pay Advance Tax on Crypto Gains in India?
Knowing the amount due is only half the process. Paying it through the correct channel, selecting the right assessment year, and verifying the credit in Form 26AS are all steps that matter. An error in any one of them can result in the payment not being credited, and interest continuing to run. Here are the steps to pay advance tax to the ITD:
Step 1: Log Into the Income Tax Portal
- Go to incometax.gov.in. Log in with your PAN and password.
- Navigate to e-Pay Tax.
- Select Challan 280 (ITNS 280). This is the only correct challan for advance tax on income, do not use Challan 281 (TDS) or Challan 282.
Step 2: Select the Correct Assessment Year and Payment Type
- For all FY 2025-26 advance tax payments, select Assessment Year 2026-27. Under “Type of Payment,” select Advance Tax (100).
Selecting Self-Assessment Tax (300) by mistake does not forfeit the credit, but it creates a reconciliation discrepancy that requires correction before filing.
Step 3: Enter the Amount and Complete Payment
- Enter the advance tax amount calculated for the current instalment. Pay via net banking, debit card, or NEFT/RTGS through an authorised bank.
- Download and save the challan counterfoil immediately. It contains the BSR code, challan date, and serial number, all required to claim the advance tax credit in the ITR.
Step 4: Verify the Credit in Form 26AS
- After payment, log back into the income tax portal and check Part C of Form 26AS within 3 to 5 working days. The advance tax payment should appear there.
- If it does not, check that the PAN and assessment year entered on the challan were correct. An incorrect entry can be corrected via a challan correction request filed with the Assessing Officer.
Does the New Income Tax Act 2025 Change Advance Tax on Crypto?
The Income Tax Act 2025 came into force on 1st April 2026. Many taxpayers have asked whether it changes advance tax obligations for FY 2025-26. The short answer is no, but understanding the transition boundary clearly matters, particularly for traders who receive notices or assessments after April 2026.
What the New Act Says About Advance Tax?
The Income Tax Act 2025 restates the advance tax framework in Section 425. The instalment percentages, the INR 10,000 trigger, and the 1% monthly interest rate are all unchanged. The new Act presents the provisions in a clearer tabular form, but no substantive change applies to the calculations or obligations for FY 2025-26.
What CBDT Has Confirmed for FY 2025-26 Filers?
The CBDT confirmed via transition guidance that income earned up to 31st March 2026 remains governed by the Income Tax Act, 1961. Advance tax obligations created during FY 2025-26, and any consequential interest under Sections 234B and 234C, are assessed under the 1961 Act, regardless of when the notice or assessment is raised after 1st April 2026.
How to Report Advance Tax Paid on Crypto in Your ITR?
Paying advance tax on time is only effective if it is reported correctly in the ITR. Unreported advance tax payments are not automatically matched to your return, the challan details must be entered manually. Errors here can result in the credit being missed and a higher tax demand being raised.
Where to Enter Advance Tax in ITR-2 and ITR-3?
In both ITR-2 and ITR-3, navigate to the Tax Paid schedule. Under “Details of Advance Tax and Self-Assessment Tax Payments,” enter each challan as a separate row. Fill in the following details for every instalment:
- BSR code of the bank where the payment was made
- Date of deposit as shown on the challan counterfoil
- Challan serial number printed on the payment receipt
- Amount paid for that specific instalment
Do not consolidate multiple quarterly payments into a single row. Each instalment must be entered individually.
Reconciling TDS Credits With Advance Tax Paid
Your total tax liability on crypto gains, 30% plus cess, minus TDS deducted under Section 194S (from Form 26AS Part A) minus advance tax paid (from Part C) equals the self-assessment tax balance due at filing.
Self-assessment tax = (30% of crypto gains + cess) − TDS under Section 194S (Form 26AS Part A) − advance tax paid (Form 26AS Part C).
Reporting advance tax correctly across multiple exchanges, four quarterly challans, and accumulated TDS credits from both Indian and foreign platforms can be prone to errors when handled manually. KoinX eliminates that risk by generating a complete Tax Paid summary, with every BSR code, challan date, and TDS credit mapped to the correct ITR schedule, so you do not miss anything while filing your ITR.
How KoinX Helps You Stay on Top of Advance Tax on Crypto?
Advance tax on crypto is a moving target, as gains fluctuate every quarter, TDS credits accumulate across multiple exchanges, and instalment liabilities must be recalculated continuously. Managing this manually across platforms like Binance, CoinDCX, WazirX, and foreign wallets increases the risk of miscalculations, missed deadlines, and interest under Section 234C.
Hence, use KoinX. This software is trusted by over 1.5 million users across 100+ countries and simplifies advance tax calculation by tracking gains in real time, reconciling TDS credits, and generating advance tax estimates before each quarterly deadline.
Real-Time Gain Tracking Across Exchanges
KoinX imports transaction data from all connected exchanges and wallets automatically. Every disposal is recorded at the correct INR FMV on the transaction date, using FIFO cost basis. Your running gain total is updated in real time, so you always know your current advance tax exposure before the quarterly deadline arrives, not after.
Automatic TDS Credit Reconciliation
As exchanges deduct TDS under Section 194S on qualifying disposals, KoinX reconciles those credits against your running tax liability automatically. The advance tax estimate it generates already reflects accumulated TDS deductions, so you are not calculating the residual manually or risking a double-payment by ignoring credits already sitting in Form 26AS.
Quarterly Advance Tax Estimate Reports
Before each instalment deadline, KoinX generates a quarterly advance tax estimate based on actual gains to date. The report shows the cumulative tax liability, total TDS deducted, advance tax already paid in earlier instalment, and the net amount due for the current quarter, in the exact format needed to complete the Challan 280 payment.
ITR-Ready Schedule VDA and Tax Paid Reports
During filing, KoinX produces an ITR-ready Schedule VDA report alongside a Tax Paid summary, listing each advance tax payment with its BSR code, date, and challan amount. Both reports plug directly into ITR-2 or ITR-3, removing the need to manually extract figures from multiple exchange statements and challan counterfoils.
Advance tax deadlines do not wait. Connect your exchanges on KoinX today to track your running gains and pay each instalment with the correct figures to avoid interest accumulation per Section 234C.
Conclusion
Advance tax on crypto gains is not optional, and at a 30% flat rate under Section 115BBH, the INR 10,000 trigger arrives faster than most investors expect. Four deadlines, two interest provisions, and a specific payment process all require attention across the financial year. Whether you trade frequently or sell crypto once during a market high, knowing your quarterly position before each deadline is what separates a clean filing from an avoidable interest bill.
KoinX tracks your gains, reconciles your TDS credits, and generates the advance tax estimates you need before each instalment, so FY 2025-26 closes without interest surprises.
Frequently Asked Questions
I Realised in February that I Had Underpaid Advance Tax Since June. How Bad is the Interest Damage at this Point?
Section 234C interest for the June, September, and December instalment is already fixed by February, three months of 1% per month on each quarterly shortfall. That is a maximum of 3% on each missed instalment amount. Pay the remaining balance before 15th March to limit further 234C exposure and to stay above the 90% threshold, which prevents Section 234B interest from applying from 1st April onwards.
I Trade on Both Indian and Foreign Exchanges. How Do I Account for TDS Not Deducted by Foreign Platforms in My Advance Tax Calculation?
Foreign exchanges do not deduct TDS under Section 194S, that obligation falls on the Indian buyer or, in P2P trades, on the counterparty. For advance tax purposes, only TDS that has actually been deducted and appears in Form 26AS can be treated as a credit. Gains made on foreign platforms where no TDS was deducted contribute their full 30% tax liability to your advance tax calculation without any credit offset.
I Missed All Four Instalments. Is it Too Late to Pay Now?
It is never too late to pay the outstanding tax. Section 234C interest for the missed instalment is already fixed and cannot be reversed. Section 234B interest continues to run from 1st April until the date of payment. Pay the outstanding amount as self-assessment tax via Challan 280, selecting AY 2026-27, and enter the payment in the Tax Paid schedule when filing the ITR.
Can I Revise My Advance Tax Estimate Downward If My Crypto Gains Fell after June?
Yes. Advance tax estimates are revised at every quarterly deadline. If gains in Q2 were lower than estimated in Q1, recalculate the annual estimate and apply the cumulative percentage to the revised figure. If you overpay in June compared to the revised estimate, the extra amount is adjusted against the September liability, and any remaining excess is refunded when you file your return.
