Most crypto investors know that gains are taxed at 30% under Section 115BBH. Fewer realise that this tax is not collected “only” at the end of the financial year. The Income Tax Department expects you to estimate your liability and pay it in four installments, the first of which falls on June 15, 2026.
Missing that deadline is not just an administrative slip. Under Section 234C, a shortfall in your Q1 payment attracts 1% interest per month for three months on the unpaid amount. On an estimated annual liability of INR 1,00,000, that is INR 450 in interest for a single missed instalment, with similar interest applying independently for Q2, Q3, and Q4 shortfalls also under Section 234C. Additionally, if the total advance tax paid is less than 90% of the assessed tax, a separate liability arises under Section 234B.
Hence, this guide is built as two separate checklists, one for active traders working across multiple exchanges and one for passive investors who made a handful of trades in Q1. Choose the track that fits your situation, and you will have everything you need to calculate, verify, and pay before June 15th.
Key Takeaways
- Advance tax is governed under Section 207 of the Income Tax Act, 1961, as amended by the Finance Act 2025.

- Q1 covers April 1 to May 31, 2026, only realised gains in this window count toward the calculation.
- The FIFO method is the ITD-recommended approach for calculating the cost of acquisition on crypto trades.
- Crypto losses cannot be set off against gains or any other income under Section 115BBH, each gain stands alone.
- 1% TDS deducted by Indian exchanges under Section 194S is visible in your AIS, verify it before paying.
- Foreign exchange holdings must be reported in Schedule FA, non-disclosure attracts penalties under the Black Money Act, 2015.
What Is Q1 Advance Tax for Crypto Investors in India?
Advance tax is income tax paid during the financial year itself, not as a lump sum after it ends. It is governed under Sections 207 to 219 of the Income Tax Act, 1961. Any taxpayer whose estimated tax liability exceeds INR 10,000 after TDS must pay in quarterly installments.
Why Does Advance Tax Apply to Crypto?
When you sell crypto on an Indian exchange, the platform deducts 1% TDS under Section 194S automatically. That deduction is not your full tax obligation, it is a small advance payment that the ITD uses to track your activity. The remaining 29% of your gain, plus 4% cess, stays outstanding until you pay it.
The ITD does not wait until July 31st (next year) for this payment. It expects you to estimate your annual liability at the start of the year and settle it progressively across four quarters. Crypto investors who ignore this and pay everything at filing time face interest charges that accumulate from June 15th onwards (the deadline for Quarter 1 advance tax payment).
What Counts as Q1 for Crypto Investors?
Q1 covers the period from April 1, 2026, to May 31, 2026. Only gains that were realised in this window count, meaning only trades that were completed, not positions still held. Every sale, swap, or crypto-to-crypto exchange executed in this period is a taxable event under Section 115BBH.
Note: Simply holding crypto, even if its value has increased significantly, is not a taxable event. The liability arises at the moment of transfer, not at the moment of appreciation. This distinction matters when estimating Q1 gains, because unrealised positions must be excluded from the calculation entirely.
Advance Tax Due Dates for FY 2025-26
The ITD splits your annual tax liability across four fixed deadlines. Missing any one of them triggers interest, so knowing the exact dates before you calculate is essential.
Instalment | Due Date | Amount to Pay |
Q1 | On or before June 15, 2026 | 15% of estimated annual tax liability |
Q2 | On or before September 15, 2026 | 45% of estimated annual tax liability minus amount already paid |
Q3 | On or before December 15, 2026 | 75% of estimated annual tax liability minus amount already paid |
Q4 | On or before March 15, 2027 | 100% of estimated annual tax liability minus amount already paid |
Note: Taxpayers under the presumptive scheme, Section 44AD or Section 44ADA, pay 100% in a single instalment by March 15, 2027.
Q1 - Advance Tax Checklist for Active Crypto Traders in India
You are an active trader if you are operating across multiple exchanges, executing frequent trades, or using leveraged positions; you have a more complex Q1 picture than a passive investor. All crypto gains must be aggregated across every platform.
FIFO must be applied individually for each token, and TDS reconciliation is rarely simple when foreign exchanges are involved. Hence, we have created a checklist for you that you can tick before the Q1 advance tax payment:
Aggregate All Q1 Gains Across Every Exchange
Pull your complete transaction history from every platform you used between April 1 and May 31, 2026. This includes WazirX, CoinDCX, Binance, Bybit, and any other exchange where a trade was executed. Every taxable event must be captured, including sell orders, crypto-to-crypto swaps, futures settlements, and any instance of spending crypto to purchase goods or services.
Do not rely on exchange summary figures for this step. Exchange reports often show total trade volume rather than net gain. Download the raw transaction history and calculate gains independently for each trade.
Apply the FIFO Method to Every Trade
The ITD recommends the First-In, First-Out (FIFO) method for calculating the cost of acquisition on crypto assets. Under FIFO, the earliest acquired units of a token are treated as the first ones sold. This applies per token across all exchanges, not per exchange individually.
Maintain a log for each token: acquisition date, acquisition cost in INR, sale date, and sale value in INR. If you purchased the same token across multiple exchanges at different prices, the oldest purchase price is used first, regardless of which exchange the sale occurred on.
Calculate Your Q1 Net Gain
For each completed trade, the gain equals the sale value in INR minus the cost of acquisition in INR. Add all individual gains across every platform to arrive at your total Q1 realised gain. The tax on this figure is 30% plus 4% health and education cess, no deductions other than the cost of acquisition are permitted.
Confirm the No-Loss-Offset Rule Applies
This is the rule that catches most active traders off guard. Under Section 115BBH, a loss on one crypto asset cannot reduce a gain on another. An INR 50,000 loss on ETH does not reduce an INR 80,000 gain on BTC. Your taxable gain remains INR 80,000.
Losses also cannot be carried forward to the next quarter or the next financial year. They cannot be set off against salary, business income, or any other head of income. Every gain is calculated and taxed in isolation, the total of your gains is your taxable figure, period.
Verify TDS Credits in AIS and Form 26AS
Log in to incometax.gov.in and open your Annual Information Statement (AIS). Indian exchanges auto-deduct 1% TDS under Section 194S and report it to the ITD, this will appear in your AIS before you have filed anything.
Match every TDS entry in your AIS against your own transaction records. Discrepancies between what the exchange reported and what you calculate are common, particularly where an exchange reports gross trade volume rather than net proceeds.
For foreign exchange trades, no automatic TDS deduction occurs. For P2P trades, verify that the buyer filed Form 26QE. Any gap reduces the TDS credit you can claim.
Estimate Your Full-Year Tax Liability
The Q1 instalment is 15% of your estimated full-year liability, not just your Q1 gain. Project your likely gains for Q2, Q3, and Q4 based on your Q1 activity and your expected trading volume through March 2026. Be conservative. Over-estimating now means a refund later. Under-estimating means interest charges on the shortfall.
Start with your estimated annual gain and apply the following:
Estimated Annual Gain × 30% × 1.04 | Estimated Annual Tax |
Estimated Annual Tax − TDS reflected in AIS | Net Tax Liability |
Net Tax Liability × 15% | Q1 Instalment Due |
If your Net Tax Liability exceeds INR 10,000, the advance tax obligation applies. Your Q1 payment is 15% of the Net Tax Liability, not 15% of the gross tax figure before TDS is deducted.
Paying on the gross figure leads to over-payment, while ignoring TDS entirely understates the credit available to you.
Check Your Foreign Exchange Holdings
If you hold crypto on any foreign platform, Schedule FA reporting applies. Schedule FA must be completed in ITR-3 and covers all foreign assets held at any point during the financial year. This is a separate obligation from the capital gains calculation.
Non-disclosure of foreign crypto holdings is not treated as a missed tax payment. It is treated as a violation of the Black Money (Undisclosed Foreign Income and Assets) and Imposition of Tax Act, 2015, which carries penalties far exceeding the tax owed on the gains themselves.
Pay 15% of the Estimated Annual Tax by June 15, 2026
Advance tax payments for crypto gains must be deposited correctly to avoid interest penalties and ensure smooth ITR-3 filing later.
- Go to the Income Tax e-Filing Portal and navigate to e-Pay Tax.
- Select Income Tax as the payment type.
- Choose Assessment Year 2026-27.
- Select Advance Tax with payment code 100.
- Enter the tax amount, applicable surcharge, and 4% cess in the relevant fields.
- Complete the payment and save the challan immediately.
- Keep the BSR code and challan serial number safely, as they are required while filing ITR-3.
Q1 - Advance Tax Checklist for Passive Crypto Investor in India
You are a passive investor if you bought and held through most of the year, or executed one or two trades in Q1. You then have a simpler calculation than active traders. However, in case of advance tax payment the same rules apply, but the data volume is smaller and the estimation is simpler. So here’s a checklist to pay your advance tax on time:
Identify Your Q1 Taxable Events
Begin by asking one question: Did you sell, swap, or spend any crypto between April 1 and May 31, 2026? If the answer is no, you have no Q1 realised gain and no advance tax obligation for this instalment. Simply holding crypto through Q1, regardless of how much its value has moved, does not create a tax liability.
If you executed a transaction in this period, identify each one. A single ETH sale, a USDT withdrawal used to purchase something, or a BTC-to-ETH swap all qualify as taxable events. Each must be included in the gain calculation.
Calculate Your Gain on Each Transaction
For each transaction, the gain equals the sale value in INR minus what you originally paid for it in INR. Use FIFO if you purchased the same token in multiple batches at different prices, the oldest purchase price applies first.
The tax rate is 30% flat on the gain, plus 4% health and education cess. No other deductions apply. If the sale resulted in a loss, that loss does not reduce any other gain, under Section 115BBH, it is simply disregarded for tax purposes. For a full breakdown of how gains are calculated, see our complete guide to crypto tax in India.
Check Your TDS Credits
Log in to incometax.gov.in and open your AIS. If you sold on an Indian exchange, 1% TDS was automatically deducted under Section 194S and will appear in your AIS. Confirm that the TDS figure matches your transaction record.
This TDS credit reduces your final tax liability when you file your ITR. For the advance tax calculation, subtract confirmed TDS from your estimated annual tax to arrive at your net payable figure.
Check the INR 10,000 Threshold
Add up your total estimated tax liability for the full financial year, not just Q1. Factor in any further trades you expect to make between June 2026 and March 2027. Subtract all TDS credits confirmed in your AIS.
If the result is below INR 10,000, you are not required to pay advance tax this quarter. If it exceeds INR 10,000, the 15% Q1 instalment applies to the full net annual figure, not just to Q1 gains alone.
Pay Online Before June 15, 2026
Here’s how you can pay your advance taxes for Quarter – 1, i.e., the June 15th, 2026 deadline.
- Go to the Income Tax e-Filing Portal and navigate to e-Pay Tax.
- Select Income Tax, Assessment Year 2026-27, and Advance Tax with payment code 100.
- Enter the tax amount, surcharge (if applicable), and 4% cess in the relevant fields.
- Save the challan after payment, as the BSR code and challan serial number must be entered while filing ITR-2.
What Happens If You Miss the June 15th Deadline?
Missing the Q1 deadline does not forfeit the entire year, but the interest starts accumulating from the day after the due date. Understanding exactly how it is calculated helps you decide whether to pay late or wait and add the shortfall to the Q2 instalment.
Section 234C Interest
Under Section 234C, interest applies when the Q1 advance tax paid is less than 15% of the annual tax liability. The rate is 1% per month for three months on the shortfall amount.
One important relief provision exists: if you paid at least 12% of your annual liability by June 15th, Section 234C interest does not apply for Q1. This gives investors a small buffer when the Q1 estimate is slightly off.
Section 234B Interest
Section 234C covers quarterly shortfalls. Section 234B covers the full-year position. If your total advance tax paid across all four installments is less than 90% of your annual liability by March 31st, Section 234B interest applies at 1% per month from April 1st until the date of actual payment.
A missed Q1 instalment is a relatively contained problem. Consistently underpaying across Q1, Q2, Q3, and Q4 creates a Section 234B charge that compounds monthly through the filing period. For active traders with large gains, this can become a significant additional liability.
How To Report Q1 Advance Tax in Your ITR?
The advance tax paid in June does not automatically appear in your return, it must be entered manually using the challan details saved at the time of payment. Errors in this entry, or a mismatch between the challan details and the ITD’s records, can result in a defective return notice even when the tax itself was paid correctly.
Step 1: Choose the Correct ITR Form
The form you file depends on the nature of your crypto activity. Active traders with PGBP income file ITR-3. Passive investors reporting crypto gains as capital gains file ITR-2. Filing the wrong form, even with correct figures, constitutes a defective return. If you are unsure which form applies to your situation, see our guide on which ITR form to file for crypto income.
Step 2: Enter Advance Tax Challan Details
Inside your chosen ITR form, navigate to the Tax Paid section. Enter the BSR code, challan serial number, date of deposit, and amount paid for each instalment separately. Do not combine Q1, Q2, Q3, and Q4 into a single entry, the ITD matches each challan individually against its payment records. A mismatch between what you enter and what the ITD holds triggers a defective return notice.
Step 3: Fill Schedule VDA
Under Schedule VDA, log every crypto disposal that occurred during the financial year. For each entry, record the date of acquisition, date of transfer, cost of acquisition in INR, sale value in INR, and the resulting gain. Each disposal is entered individually, not as a lump sum.
The gain figures in Schedule VDA must be consistent with the advance tax liability you paid across all four instalments.
Step 4: Reconcile TDS Credits Against AIS and Form 26AS
Before submitting your return, cross-check every TDS credit in your AIS against your transaction records. Indian exchanges sometimes report gross trade volume rather than net proceeds as SFT data, which inflates the AIS figure relative to actual TDS deducted.
Claim only the TDS you can verify against a specific transaction. An unexplained gap between the AIS figure and your declared Schedule VDA gain is one of the most common triggers for an ITD scrutiny notice.
Step 5: Pay Any Remaining Liability and File
After adjusting all TDS credits and advance tax payments, calculate whether any outstanding liability remains. Settle this as self-assessment tax before submitting the return. The ITR filing deadline for FY 2026-27 (AY 2027-28) for non-audit cases is 31st July 2027. Audit cases under Section 44AB have until 31st October 2027.
Aggregating gains across multiple exchanges, applying FIFO correctly, reconciling TDS credits, and maintaining challan records across four instalments is a significant data management task. The more platforms you use, the harder it becomes to produce a figure you can stand behind when you file. That is the exact problem KoinX is built to solve for Indian crypto investors.
How KoinX Can Help With Q1 Advance Tax on Crypto in India?
Advance tax on crypto is not a single calculation, it is four calculations across a full financial year, each built on transaction data from every exchange you use. When that data spans Indian and foreign platforms, multiple tokens, and hundreds of trades, manual methods produce errors. KoinX connects to 800+ exchanges and wallets, imports your transaction data automatically, and generates the gain figures, TDS reconciliations, and ITR-ready reports you need for every installment.
Automatic Q1 Gain Calculation Across All Exchanges
KoinX imports transaction data directly from every connected exchange, Indian and foreign, and calculates your Q1 realised gains automatically. Each sale, swap, and crypto-to-crypto trade is identified as a taxable event, converted to INR at the correct FMV on the transaction date, and included in the gain summary without manual data entry.
FIFO Cost Basis Applied Automatically
KoinX applies the FIFO method automatically across all connected exchanges. When the same token is held across multiple platforms at different acquisition prices, KoinX sequences the cost basis correctly per the ITD’s recommended method, eliminating the most common calculation error in multi-exchange portfolios.
TDS Reconciliation Against AIS and Form 26AS
KoinX cross-references TDS deducted by each connected exchange against your transaction records and flags any discrepancy before you calculate your advance tax instalment. Where AIS data is inflated due to gross volume reporting, KoinX identifies the gap and prepares the reconciliation data you need.
ITR-Ready Reports for ITR-2 and ITR-3
Once your advance tax instalments are paid, KoinX generates Schedule VDA reports formatted for both ITR-2 and ITR-3, with challan entry fields pre-mapped to the correct sections of the return. Every gain, every TDS credit, and every installment is accounted for in a single output.
Calculate your Q1 advance tax liability in minutes, connect your exchanges to KoinX, and get your ITR-ready report before June 15, 2026.
Conclusion
The June 15th deadline is not optional, Section 234C interest begins accumulating the day after it passes, and Section 234B compounds that exposure across every subsequent quarter where the shortfall grows. On an annual crypto tax liability of INR 2,00,000, consistently underpaying across all four instalments can add INR 6,000 or more in interest before you ever open the filing portal.
KoinX automates the gain calculation, TDS reconciliation, and report generation across every exchange you use. So get started with KoinX today and make your June 15th payment based on accurate figures, not estimates made from incomplete records.
Frequently Asked Questions
I Only Traded Once in April 2026. Do I Still Need to Pay Advance Tax by June 15th?
It depends on your full-year estimated tax liability, not just the April trade. Calculate your gain on that single transaction, apply 30% plus 4% cess, and subtract the TDS deducted by the exchange. If the resulting net tax liability for the full year exceeds INR 10,000, the advance tax obligation applies, and 15% is due by June 15th. If it is below INR 10,000, no advance tax payment is required this quarter.
My Q1 Crypto Losses Were Bigger Than My Gains. Do I Still Owe Advance Tax?
Under Section 115BBH, losses from one crypto asset cannot be set off against gains from another, nor against any other income. If your Q1 gains totalled INR 60,000 and your Q1 losses totalled INR 90,000, your taxable gain is still INR 60,000, the losses are disregarded entirely. If your tax on that INR 60,000 gain, after TDS, exceeds INR 10,000 for the year, advance tax applies.
I Use Three Foreign Exchanges and One Indian Exchange. How Do I Calculate My Q1 Gain?
Aggregate the transaction history from all four platforms and treat them as a single pool. Apply FIFO per token across all exchanges combined, not per exchange separately. Convert every transaction to INR at the FMV on the date of each trade. For foreign exchange trades, no TDS was automatically deducted, so the full 30% plus cess applies to those gains without any TDS credit to offset.
The TDS in My AIS Does Not Match What the Exchange Told Me Was Deducted. What Do I Do?
This is a common discrepancy. Indian exchanges sometimes report gross trade volume to the ITD as SFT data, which inflates the AIS figure relative to actual TDS. Do not use the AIS figure for your advance tax calculation without verifying it against your own transaction records. Prepare a written reconciliation of the difference and retain it. If the AIS figure is higher, do not claim a TDS credit you did not actually receive.
I Missed the June 15th Deadline. Can I Still Pay Now Without a Penalty?
You can pay at any time, there is no bar on late payment. However, Section 234C interest of 1% per month applies for up to three months on the Q1 shortfall. Paying immediately after the missed deadline minimises the interest. If you pay the full Q1 shortfall before September 15th, the Section 234C clock stops. File a revised return under Section 139(5) if you have already submitted an ITR that did not reflect the payment correctly.
I Am a Salaried Employee Who Also Trades Crypto. Does My Employer's TDS Reduce My Advance Tax Obligation?
Yes. TDS deducted by your employer under Section 192 is credited against your total annual tax liability, the same way TDS deducted by exchanges under Section 194S is. Add both TDS credits together and subtract from your estimated annual tax. If the net figure is below INR 10,000, no advance tax is due. If it exceeds INR 10,000, the 15% Q1 instalment applies to the net amount after both TDS credits.
How Do I Know If I Need to Fill Schedule FA for My Foreign Exchange Holdings?
Schedule FA is required in ITR-3 for any taxpayer who holds assets in a foreign account or on a foreign platform at any point during the financial year. If you had crypto on Binance, Bybit, Kraken, or any other non-Indian exchange on any single day between April 1, 2025, and March 31, 2026, Schedule FA applies. This is an asset declaration, not a tax calculation. The obligation exists regardless of whether you made gains or losses on those holdings.
