Managing crypto tax compliance for multiple clients is not just about remembering due dates. It involves tracking different filing obligations based on each client’s trading activity, income profile, and reporting requirements throughout the financial year. While one client may only require an ITR-2 filing by 31st July, another operating a crypto mining business may need to file ITR-3 by 31st August, with a possible audit deadline in October. Alongside these annual obligations, TDS deposits under Section 194S for every crypto transfer are due within 30 days from the end of month in which it was deducted.
The real challenge for Chartered Accountants is coordinating these overlapping deadlines across multiple clients without disrupting their compliance workflow. Managing five different deadline stacks across fifteen different clients simultaneously requires a structured approach, particularly when crypto transactions are involved. A missed TDS deposit on a single client’s P2P trade attracts a penalty equal to 100% of the unpaid tax under Section 271C. A miscalculated advance tax instalment triggers interest under Section 424 (corresponding to Section 234B) and Section 425 (corresponding to Section 234C) of the Income Tax Act, 2025, at 1% or 3% per month depending on the nature of the shortfall.
This guide brings every crypto-relevant tax deadline for FY 2025-26 and FY 2026-27 together in one place. It explains which deadlines apply to different categories of crypto clients, highlights the compliance obligations CAs need to monitor throughout the year, and provides a practical framework to organise workloads efficiently while managing multiple crypto engagements across India.
Key Takeaways
- Crypto clients fall into four filing profiles, ITR-2 investors, ITR-3 Profits and Gains of Business or Profession(PGBP) filers, ITR-3 audit cases, and each carrying a different ITR deadline.
- The ITR-2 filing deadline for FY 2025-26 is 31st July 2026; ITR-3 non-audit cases must file by 31st August 2026; audit cases by 31st October 2026.
- Advance tax for FY 2026-27 is governed by the Income-tax Act, 2025, it does not apply to FY 2025-26 filings, which remain under the Income Tax Act, 1961.
- Form No. 142, the quarterly VDA TDS return, must be filed by 31st July 2026 for the quarter ending June 2026.
- TDS on every crypto transfer under Section 194S is a monthly deposit obligation within 30 days from the end of month in which it was deducted.
- Missed advance tax instalments attract 1% interest under under Section 424 (corresponding to Section 234B of the old act) and 1% to 3% interest under Section 425 (corresponding to Section 234C of the old act); missed TDS deposits attract a penalty equal to 100% of unpaid tax under Section 271C.
What Are the Crypto Tax Deadlines for FY 2025-26?
All deadlines in this section apply to FY 2025-26 returns filed under the Income Tax Act, 1961. The Income-tax Act, 2025 does not govern FY 2025-26 filings, its provisions take effect from 1st April 2026 onward, which means they apply to FY 2026-27 advance tax, covered separately below.
Master Deadline Table - FY 2025-26 Crypto Obligations
The table below consolidates every crypto-specific compliance obligation for FY 2025-26 into a single reference. Each row maps the deadline to the applicable client type and the governing provision:
Deadline | Obligation | Applicable Client Type | Relevant Section |
Within 30 days from the end of month of deduction | TDS deposit on prior month’s crypto transfers | All clients with disposal activity | |
7th of the month following the month of deduction | TDS deposit on crypto salary and ESOP perquisite | Salaried and ESOP clients | |
7th of the month following the month of deduction | TDS deposit on consulting or freelance fees in crypto | Consulting clients with Indian payers | |
Within 30 days from the end of month of deduction | Form 26QE, P2P TDS challan-cum-statement | P2P clients who self-deducted TDS | |
31st July 2026 | ITR filing, non-audit investor clients | ITR-2 | |
31st July 2026 | Form No. 142, quarterly VDA TDS return | Crypto exchanges and intermediaries | |
31st August 2026 | ITR filing, non-audit PGBP clients | ITR-3 | |
31st October 2026 | ITR filing, audit cases | ITR-3 with Section 44AB audit | |
31st December 2026 | Belated return | All clients who missed primary deadline |
TDS Deposit Deadlines for Crypto Clients
Every crypto transfer triggers a 1% TDS obligation under Section 194S, which must be deposited by the 7th of the following month. This is either auto-deducted by Indian exchanges or self-deposited via Challan ITNS 281 for foreign platform and P2P clients.
Additionally, employers paying salary in crypto and Indian clients paying consulting fees have separate monthly obligations under Section 192 and Section 194J respectively. However, both follow the same 7th-of-the-month deposit deadline, making monthly compliance tracking essential across different client categories.
ITR Filing Deadlines for Crypto Clients
Once monthly TDS obligations are addressed, the focus shifts to annual return filing. ITR-2 investor clients must file by 31st July 2026. ITR-3 PGBP clients, including trading desk operators, PGBP freelancers, and systematic P2P traders, must file by 31st August 2026.
Meanwhile, audit-bound clients under Section 44AB have until 31st October 2026 to file. If any return is missed, belated filing remains available under Section 139(4) until 31st December 2026, subject to a late fee under Section 234F.
Quarterly TDS Return Deadlines
Beyond monthly deposits and annual returns, quarterly TDS reporting requires equal attention. For the quarter ending 30th June 2026, Form No. 140 covering non-salary TDS, including consulting fees paid in crypto, and Form No. 138 for salary TDS must both be filed by 31st July 2026.
In addition, P2P clients who self-deduct TDS must file Form 26QE within 30 days from the end of the month in which it was deducted. Before submitting the ITR, all TDS credits should also be reconciled against Form 26AS and the Annual Information Statement to ensure reporting consistency.
Form No. 142 – VDA TDS Quarterly Return
Alongside these filings, Form No. 142 serves as the dedicated quarterly return for VDA-related TDS. It must be filed by cryptocurrency exchanges and eligible intermediaries by 31st July 2026 for the quarter ending June 2026.
For CAs, this form acts as the benchmark for reconciling every client’s Schedule VDA entries. Consequently, any discrepancy between the exchange’s Form 142 data and the client’s declared gains will appear as an AIS mismatch before and after filing.
What Are the Advance Tax Deadlines for Crypto Clients for FY 2026-27?
Advance tax for FY 2026-27 is governed by the Income-tax Act, 2025, which came into effect on 1st April 2026. These provisions apply only to income earned from FY 2026-27 onward:
Advance Tax Instalment Schedule for FY 2026-27
The threshold for advance tax liability under Section 404 of the Income-Tax Act, 2025 remains INR 10,000 after adjusting TDS credits, unchanged from the prior law. A crypto client whose estimated annual tax liability falls below this figure is exempt.
Short payment of any instalment attracts interest of 1% to 3% under Section 425 (corresponding to Section 234C of the old act). Failure to pay advance tax at all attracts interest under Section 424 (corresponding to Section 234B of the old act) at 1% per month on the outstanding amount. The due dates are:
Instalment | Due Date | Minimum Cumulative Advance Tax Payable |
First | 15th June 2026 | 15% of estimated annual liability |
Second | 15th September 2026 | 45% cumulative |
Third | 15th December 2026 | 75% cumulative |
Fourth | 15th March 2027 | 100% cumulative |
Why Do Crypto Clients Need Advance Tax Planning?
Advance tax applies to any crypto client whose estimated tax liability either through income or crypto gains for the year exceeds INR 10,000 after adjusting TDS credits, regardless of whether they are a trader, investor, miner, staker, yield farmer, or NFT creator.
The formula is:
Advance Tax Payable = Estimated Total Tax Liability minus TDS and TCS Credits Available.
A CA must run this calculation for every crypto client at each quarter. It is to be noted that income type does not determine the obligation, the INR 10,000 threshold does.
Skipping this calculation for any client, or carrying forward last year’s figures without reviewing current activity, risks either an overpayment or a Section 234C interest charge.
What Makes Crypto Tax Deadlines Different for CAs?

Skipping this calculation for any client, or carrying forward last year’s figures without reviewing current activity, risks either an overpayment or a Section 234C interest charge.
Managing crypto clients is not the same as managing standard income clients. Each crypto client carries recurring monthly TDS obligations, quarterly advance tax instalments, a VDA-specific return, and an ITR form that varies by income classification, all running simultaneously.
The Two-Deadline Problem Every Crypto CA Faces
Unlike salaried clients who generally follow a single filing deadline, crypto clients create compliance obligations throughout the year. TDS deposits fall on the 30 days from the end of the month when it was deducted, advance tax is payable quarterly, the quarterly VDA return falls in July, and the applicable ITR deadline depends on the client’s income classification.
As a result, a CA managing multiple crypto clients often handles a different compliance calendar for each one. One client may file ITR-2 by 31st July, another may file ITR-3 by 31st August, while an audit-bound client files in October. Missing even one deadline can create penalty or interest liability for the client and affect the CA’s professional record.
Why Client Classification Must Happen Before Deadline Planning?
Before mapping filing deadlines, every crypto client must first be classified correctly because the applicable ITR form determines the due date. An investor filing ITR-2 has until 31st July 2026, while a trading desk operator or systematic P2P trader filing ITR-3 has until 31st August 2026, or 31st October if the Section 44AB audit threshold is crossed.
Therefore, classification should be completed before document collection begins. Filing the wrong ITR form results in filing against the wrong deadline, which can trigger a defective return notice, require time-sensitive rework, and, in some cases, lead to a revised return that the client must verify and sign again.
How to Manage Crypto Tax Deadlines Across Multiple Clients?
Deadline management for a multi-client crypto practice is not a reactive exercise. It is a structured workflow built in April, before the first advance tax instalment falls, before document collection begins, and well before the July filing window opens.
Classify Every Crypto Client Before June
Before collecting documents, classify every crypto client to determine the correct ITR form, the applicable filing deadline, and whether a Section 44AB audit is required. Completing this step early ensures every engagement follows the appropriate compliance path from the outset.
To do this, review the client’s full-year activity, including income type, exchange mix, P2P exposure, PGBP indicators, and absolute turnover. Ideally, this assessment should be completed by May, giving you sufficient time to inform clients about the documents they must provide before June.
Build a Client-Wise Deadline Calendar
Once clients have been classified, organise a practice-wide calendar based on client profiles and statutory deadlines. This approach gives the entire team visibility into upcoming obligations and helps prevent multiple filings from converging at the same time.
For example, batch all ITR-2 investor clients for 31st July with internal completion targets by mid-July. Similarly, schedule all ITR-3 non-audit PGBP clients for 31st August with mid-August targets, while reserving 31st October for Section 44AB audit cases. Meanwhile, maintain advance tax reminders for FY 2026-27 as a separate recurring calendar.
Collect Client Documentation by Client Type
Once clients have been classified, organise a practice-wide calendar based on client profiles and statutory deadlines. This approach gives the entire team visibility into upcoming obligations and helps prevent multiple filings from converging at the same time.
For example, batch all ITR-2 investor clients for 31st July with internal completion targets by mid-July. Similarly, schedule all ITR-3 non-audit PGBP clients for 31st August with mid-August targets, while reserving 31st October for Section 44AB audit cases. Meanwhile, maintain advance tax reminders for FY 2026-27 as a separate recurring calendar.
Send Advance Tax Reminders at Every Quarter Boundary
In addition to annual filing deadlines, monitor advance tax obligations throughout the year. Most advance tax defaults can be avoided when clients receive timely reminders along with their estimated liability before each due date.
Therefore, send structured reminders to all PGBP crypto clients, including trading desk operators, freelancers, consultants, and content creators, on 1st June, 1st September, 1st December, and 1st March.
Each reminder should include the estimated installment, exchange TDS credits for the quarter, and the net amount payable. Although preparing each reminder takes around 30 minutes per client, it can save hours of interest calculations later.
Prioritise High-Complexity Clients First
Not every crypto client requires the same level of attention. Therefore, prioritise high-complexity engagements, especially those involving audit exposure, multiple exchanges, or unresolved P2P TDS gaps, by assigning them the earliest internal completion targets.
For instance, a trading desk operator with a Section 44AB audit requirement, activity across multiple foreign exchanges, and Form 26QE obligations should be scheduled well before October, as audit preparation alone takes weeks. Meanwhile, passive ITR-2 investors using a single Indian exchange can usually be completed in June, creating additional capacity for more demanding cases.
Use KoinX as Your Crypto Tax Software
Finally, managing multiple crypto clients becomes significantly easier when all engagements are centralised on a single platform. KoinX for Tax Professionals enables CAs to onboard multiple clients, with each client receiving a separate API integration and an independent tax computation based on their financial year and exchange activity.
As a result, client data remains completely segregated, while reports can be downloaded individually without switching platforms or maintaining separate spreadsheets. Each Complete Tax Report includes capital gains from disposals, derivatives income covering futures and options turnover, other income from staking and airdrops, and Schedule VDA data for direct ITR reporting. For Section 44AB audit cases, the derivatives section also calculates the absolute-sum turnover, comprising total realised futures profits plus total realised futures losses.
How Can KoinX Help CAs Manage Crypto Tax Deadlines?
Running a multi-client crypto practice means handling capital gains, derivatives income, staking receipts, and TDS data across multiple exchanges, for every client, every year. When that data is fragmented across different platforms and CSV files, deadline pressure compounds quickly. KoinX for Tax Professionals consolidates client-wise crypto tax computation into a single account, so a CA can generate, review, and download every client’s ITR-ready reports without switching tools.
Complete Tax Report for Every Client
KoinX generates a Complete Tax Report per client that covers capital gains from crypto disposals, derivatives income from futures and options trading, other income such as staking rewards and airdrops, and a full Schedule VDA transactions list. Opening and closing balance sheets are included for audit trail purposes. All figures are computed under the Income Tax Act, 1961 and formatted for Indian ITR filing.
Schedule VDA Report Ready for ITR Entry
The Schedule VDA report contains transaction-level data for every disposal, date of acquisition, date of transfer, cost of acquisition, and consideration received, structured for direct entry into the Schedule VDA section of ITR-2 and ITR-3. For a CA filing multiple returns across a deadline window, this removes the manual data preparation step that typically consumes the most time per client.
Derivatives Turnover Calculation for Audit Clients
For trading desk clients subject to a Section 44AB audit, KoinX calculates derivatives turnover as the absolute sum of realised futures and options profits and losses, the figure the audit report must reference. Brokerage fees, funding interest received, and funding fees paid are each itemised separately, giving the CA the granular breakdown needed for the audit without manual reconciliation across trade logs.
Multi-Client Management Under One Account
KoinX for Tax Professionals allows a CA to manage the full client portfolio from a single login. Each client is onboarded with their own API key, generating an independent tax computation for their specific exchange set and financial year. Reports are isolated per client, there is no data crossover, and each can be regenerated at no additional cost when transaction data changes before the filing deadline.
Asset-Wise Profit and Loss for Client Advisory
KoinX produces an asset-wise profit and loss summary for each client, showing gross profit, gross loss, and net gain per cryptocurrency held during the year. This helps a CA quickly identify which assets drove the taxable outcome and supports advance tax planning conversations at each instalment date, particularly for clients with large unrealised positions moving into the next quarter.
CAs managing crypto clients across multiple deadline windows can onboard their full client portfolio on KoinX and generate ITR-ready reports for each client independently. Start managing your crypto client practice on KoinX today.
Conclusion
Crypto tax compliance does not concentrate into a single deadline. It runs continuously, TDS deposits every month, advance tax every quarter, VDA returns every quarter, and ITR filings across three separate deadline windows depending on client type. A CA who enters the season without a structured workflow per client profile will find July arriving before the work is ready.
The solution is preparation that begins in April: classify every client, issue documentation checklists by profile, build a calendar that staggers work across July, August, and October, and send advance tax reminders before each instalment falls due. KoinX generates the client-wise Schedule VDA reports, derivatives turnover calculations, and Complete Tax Reports that make each step faster and more accurate, so every client files on time, with figures that hold up to scrutiny.
Frequently Asked Questions
What ITR Form Does a Crypto Investor File for FY 2025-26?
A crypto investor who holds and sells VDAs as a passive investment files ITR-2 for FY 2025-26. Gains are reported under Schedule VDA and taxed at 30% plus 4% cess under Section 115BBH. ITR-2 is not available to clients with business income;a client whose crypto activity is classified as PGBP must file ITR-3 regardless of whether they also have investment gains.
What Is the Filing Deadline for a Crypto Trading Desk Operator Subject to Section 44AB Audit?
A trading desk operator whose absolute turnover, calculated as the sum of all realised profits and realised losses, exceeds INR 1 crore must undergo a tax audit under Section 44AB. The ITR-3 filing deadline for audit cases is 31st October 2026 for FY 2025-26. Missing this deadline attracts a Section 271B penalty of 0.5% of turnover, up to a maximum of INR 1,50,000.
Who Is Responsible for Deducting TDS When a Client Sells Crypto on a Foreign Exchange?
When a client sells crypto on a foreign exchange, such as Binance or Bybit, no automatic TDS deduction occurs. The buyer in the transaction is responsible for deducting 1% TDS under Section 194S, depositing it via Challan No. ITNS 280 by the 7th of the following month, and filing Form 26QE. A CA managing clients with foreign exchange activity must ensure this obligation is tracked and met monthly throughout the financial year.
How Is Advance Tax Calculated for a Crypto Client With Section 194S TDS Credits?
Advance tax payable is calculated under Section 405 of the Income-tax Act, 2025 as: Estimated Total Tax Liability minus TDS and TCS Credits Available. TDS deducted by Indian exchanges under Section 194S appears in the client’s Form 26AS and reduces the net advance tax payable at the next instalment date. A CA must recalculate this figure at every quarter boundary using actual activity data, not an annual projection divided by four.
What Happens if a Crypto Client Misses the 31st July 2026 ITR Deadline?
A client who misses the 31st July 2026 deadline can file a belated return under Section 139(4) until 31st December 2026. A late fee under Section 234F applies, INR 5,000 for income above INR 5 lakh, or INR 1,000 for income below that threshold. Interest under Section 234A also accrues on any outstanding tax liability from the original due date. A CA should initiate the belated return immediately rather than waiting for the client to follow up.
Does the Income-tax Act, 2025 Change the ITR Filing Deadlines for FY 2025-26?
No. The Income-tax Act, 2025 came into effect on 1st April 2026 and governs income earned from TY 2026-27 onward. All FY 2025-26 ITR filings, including Schedule VDA reporting, TDS credits, and penalty provisions, remain under the Income Tax Act, 1961. The Income-tax Act, 2025 is relevant for this guide only in the context of advance tax instalments for TY 2026-27, which began with the first instalment on 15th June 2026.
What Is Form No. 142 and Which Clients Does It Affect?
Form No. 142 is the quarterly VDA TDS return filed by cryptocurrency exchanges and eligible intermediaries under the Income-tax Act, 2025. For the quarter ending 30th June 2026, it must be filed by 31st July 2026. It reports all TDS deducted on VDA transfers during that quarter. For a CA, Form 142 data is the benchmark against which every crypto client’s Schedule VDA entries must be reconciled, discrepancies between the two will appear as AIS mismatches after filing.
How Does a CA Calculate the Section 44AB Audit Turnover for a Crypto Derivatives Client?
Turnover for Section 44AB audit purposes is calculated as the absolute sum of all realised profits and realised losses from futures and options trading, not the net figure. A client with INR 80 lakh in futures gains and INR 76 lakh in futures losses has an audit turnover of INR 1,56,00,000, well above the INR 1 crore threshold. Using the net profit figure of INR 4 lakh instead is one of the most common miscalculations a CA must correct before filing.
