Every TDS and TCS deadline for FY 2026–27 under the Income-tax Act, 2025 — monthly deposit dates, quarterly statement dates, certificate dates, and the interest and fee that apply the day you are late.
Tax deducted at source is the obligation most businesses breach without noticing. The tax is deducted correctly, and then the deposit slips past the seventh, or a quarterly statement is filed a fortnight late, and a fee accrues daily until it is fixed. This calendar sets out every date for FY 2026–27, the first year under the Income-tax Act, 2025.
The section numbers have changed even though the dates have not. Deduction from salary is now section 392. The unified table of resident deduction rates is section 393. Collection at source is section 394. The tax deduction and collection account number, and the quarterly statements, sit in section 397. Failure to deduct or pay is dealt with in section 398.
Monthly Deposit Dates
| Tax deducted in | Deposit by |
|---|---|
| April 2026 | 7 May 2026 |
| May 2026 | 7 June 2026 |
| June 2026 | 7 July 2026 |
| July 2026 | 7 August 2026 |
| August 2026 | 7 September 2026 |
| September 2026 | 7 October 2026 |
| October 2026 | 7 November 2026 |
| November 2026 | 7 December 2026 |
| December 2026 | 7 January 2027 |
| January 2027 | 7 February 2027 |
| February 2027 | 7 March 2027 |
| March 2027 | 30 April 2027 |
March is the exception every year and the one people forget: tax deducted in March is payable by 30 April, not 7 April.
Quarterly Statement Dates
| Quarter | Period | Statement due |
|---|---|---|
| First | April to June 2026 | 31 July 2026 |
| Second | July to September 2026 | 31 October 2026 |
| Third | October to December 2026 | 31 January 2027 |
| Fourth | January to March 2027 | 31 May 2027 |
Certificates to Deductees
| Certificate | Due |
|---|---|
| Annual certificate of tax deducted from salary | 15 June 2027 |
| Quarterly certificate for deductions other than salary | Within fifteen days of the statement due date |
Form numbers are not stated here on purpose. The forms practitioners know as 24Q, 26Q, 27Q, 16 and 16A are prescribed by the Income-tax Rules, and the Rules made under the 2025 Act renumber them. The statutory dates above are stable; the form numbers should be confirmed on the e-filing portal before filing.
What Being Late Costs
| Default | Consequence | Provision |
|---|---|---|
| Tax deducted but not deposited | Interest at 1.5% per month or part of a month, from the date of deduction to the date of payment | Chapter XIX-B |
| Tax not deducted at all | Interest at 1% per month or part of a month, from the date it was deductible to the date it is deducted | Chapter XIX-B |
| Quarterly statement filed late | Fee of ₹200 per day, capped at the amount of tax deductible | Chapter XIX-B |
| Failure to deduct or pay | Deemed an assessee in default, with recovery and further consequences | s.398 |
| Recipient has no PAN | Deduction at a higher rate | Chapter XIX-B |
Worked example. You deduct ₹90,000 of tax in July 2026 and pay it on 3 September instead of 7 August. Interest runs at 1.5% per month or part of a month from the date of deduction, so July, August and September are each counted — three months, ₹4,050. Four days of delay past the due date costs three months of interest, because a part of a month counts as a whole one.
A Working Routine
- On every payment run: check whether the payment falls in the section 393 table, and whether the annual threshold for that payee has been crossed.
- By the 5th of each month: total the previous month's deductions and prepare the challan, so the 7th is never the day you start.
- By the 7th: deposit, and file the challan reference against each deduction.
- In the month after each quarter: reconcile deductions to challans, verify every deductee's permanent account number, then file the statement.
- Within fifteen days of each statement: issue certificates.
- Each quarter: ask deductees to confirm the credit appears in their annual information statement. Errors are far cheaper to fix in the same year.
