TDS returns are filed quarterly. The due dates are 31 July (Q1), 31 October (Q2), 31 January (Q3) and 31 May (Q4). For FY 2025-26 you file on the familiar forms — 24Q (salary), 26Q (non-salary residents), 27Q (non-residents) and 27EQ (TCS). Late filing attracts a fee of Rs 200 a day until the return is filed.
Quarterly TDS Return Due Dates
The same four dates apply to every TDS form (24Q, 26Q, 27Q) and to TCS (27EQ). Q4 has a longer window — 31 May — to allow year-end salary reconciliation and issue of Form 16 / 16A.
| Quarter | Period | Filing Due Date | Forms |
|---|---|---|---|
| Q1 | 1 Apr – 30 Jun | 31 July | 24Q · 26Q · 27Q · 27EQ |
| Q2 | 1 Jul – 30 Sep | 31 October | 24Q · 26Q · 27Q · 27EQ |
| Q3 | 1 Oct – 31 Dec | 31 January | 24Q · 26Q · 27Q · 27EQ |
| Q4 | 1 Jan – 31 Mar | 31 May | 24Q · 26Q · 27Q · 27EQ |
Dates shown for FY 2025-26 (Q1 due 31 Jul 2025 … Q4 due 31 May 2026). The same pattern repeats every year.
For deductions made on or after 1 April 2026 (FY 2026-27), the Income-tax Act, 2025 consolidates TDS into Section 392 (salary → new Form 138) and Section 393 (non-salary residents → Form 140; non-residents → Form 144). The quarterly due dates (31 Jul / 31 Oct / 31 Jan / 31 May) are unchanged — only the form numbers change. FY 2025-26 returns continue on 24Q / 26Q / 27Q.
TDS Deposit (Challan) Due Dates
Depositing the tax and filing the return are two separate deadlines. TDS deducted in a month must be paid to the government by the 7th of the next month, well before the quarterly return.
| TDS deducted in | Deposit due date | Applies to |
|---|---|---|
| Apr to Feb (any month) | 7th of the following month | All non-government deductors |
| March | 30 April | All non-government deductors |
| Any month (govt, book entry) | Same day | Government deductors |
Deposit via challan-cum-statement / e-payment on the income-tax portal. Missing the deposit date triggers interest, separate from the return late fee.
A common error is treating the quarterly return date as the payment date. The tax itself is due by the 7th of the next month (30 April for March deductions); the quarterly return simply reports what was already deposited. Late deposit attracts 1.5% interest per month even if the return is on time.

The correct form depends on what was deducted and to whom. Check your applicable rate and threshold in the TDS rate chart before filing.

|---|---|---|---|
| 24Q | Form 138 | Section 392 | TDS on salary |
| 26Q | Form 140 | Section 393(1) | TDS on non-salary payments to residents (interest, rent, contract, professional fees) |
| 27Q | Form 144 | Section 393(2) | TDS on payments to non-residents |
| 27EQ | Form 140 (TCS) | Section 394 | Tax Collected at Source (TCS) |
Old section numbers (192, 194-series, 195, 206C) are discontinued on TRACES for post-1 Apr 2026 transactions; returns use the new numeric payment codes.
- Valid TAN (Tax Deduction Account Number)
- Challan / BSR details of TDS deposited
- PAN of every deductee
- Deduction amount and correct section code
- Form 16 / 16A ready to issue after filing
- DSC or EVC to sign the return
Late Filing Fee, Penalty & Interest
- Late-filing fee — Rs 200 per day (old Section 234E, renumbered Section 427 from 1 Apr 2026) from the due date until filing, capped at the total TDS in the return.
- Penalty for non-filing — Rs 10,000 to Rs 1,00,000 (old Section 271H, new Section 461) at the Assessing Officer's discretion.
- Interest on late deposit — 1.5% per month (or part) from the date of deduction to the date of deposit.
- Interest on non-deduction — 1% per month from the date TDS was deductible to the date it was actually deducted.
Failure to deposit TDS after deducting it can attract prosecution — imprisonment of 3 months to 7 years plus fine. Always deposit deducted TDS by the 7th of the next month; the late fee and interest add up quickly.
