GST & TDS Due Date Calendar
The recurring deadlines, with a live count of how many days you have left on each. Missed due dates are almost always a process problem rather than an intent problem — so here is the process, on one page.

Quarterly and annual GST
| Return | Due |
|---|---|
| GSTR-1 (QRMP) Quarterly outward supplies | 13th of the month after the quarter |
| GSTR-3B (QRMP) Quarterly summary return. The date depends on your state; Maharashtra falls on the 22nd | 22nd or 24th of the month after the quarter |
| CMP-08 Tax payment statement for composition taxpayers | 18th of the month after the quarter |
| GSTR-9 / 9C Annual return for the previous financial year, with the reconciliation statement above ₹5 crore of turnover | 31 December |
Quarterly TDS returns
| Quarter | Forms | Due |
|---|---|---|
| Q1 (Apr–Jun) | 138 / 140 / 144 (was 24Q / 26Q / 27Q) | 31 July |
| Q2 (Jul–Sep) | 138 / 140 / 144 (was 24Q / 26Q / 27Q) | 31 October |
| Q3 (Oct–Dec) | 138 / 140 / 144 (was 24Q / 26Q / 27Q) | 31 January |
| Q4 (Jan–Mar) | 138 / 140 / 144 (was 24Q / 26Q / 27Q) | 31 May |
March TDS is the exception. Deductions made in March are payable by 30 April rather than 7 April. It is the single most commonly missed date in the year, because it breaks the monthly habit.
Not sure which of these apply to you? The GST applicability checker shows which returns and rules apply at your turnover.
Extensions happen. The government issues due-date extension notifications fairly often. Treat this as the standing rule and check the GST portal for any notification covering your period before you rely on a date.
Why businesses miss dates they know about
Almost nobody misses a GST deadline because they forgot it exists. They miss it because the data wasn’t ready — a purchase register still being chased, a bank statement not downloaded, a credit note nobody decided on. The deadline was never the constraint; the input was.
Which is why “set a reminder” fixes very little. What fixes it is pulling the work forward: a fixed internal cut-off several days before the statutory date, so the return is prepared against complete data with room to resolve whatever doesn’t tie.
A working internal calendar
| By | What happens |
|---|---|
| 2nd | Source data complete — bank, sales, purchase, expenses |
| 5th | Books posted and reconciled; TDS computed and deposited by the 7th |
| 8th | GSTR-2B pulled and matched to the purchase register; mismatches raised with suppliers |
| 10th | GSTR-1 prepared and reviewed, filed by the 11th |
| 18th | GSTR-3B reconciled to books and filed, ahead of the 20th |
Note the gap between the 8th and the 11th. That is deliberate — it is the room to chase a supplier who hasn’t filed, which is impossible on the 20th and easy on the 8th.
The cost of getting this wrong
Late fees accrue daily until the return is filed, and interest runs at 18% on tax paid in cash. Size it for your own delay with the late fee calculator. But the fee is rarely the real cost — a late GSTR-1 delays your customers’ input credit, they notice, and it quietly damages a commercial relationship in a way no penalty shows.
If this calendar is currently held in one person’s head, that is the actual risk. Our GST and TDS service runs it as a tracked process across every entity and GSTIN you hold.
Due dates — common questions
When is GSTR-3B due?
For monthly filers, the 20th of the following month. Under the QRMP scheme the return is quarterly, with a staggered due date, while tax is still deposited monthly through PMT-06 by the 25th.
When is GSTR-1 due?
The 11th of the following month for monthly filers. QRMP filers file quarterly by the 13th after the quarter ends, and may optionally use the IFF by the 13th in the first two months of the quarter to pass credit to their B2B customers sooner.
When must TDS be deposited?
By the 7th of the following month for deductions made in April through February. March deductions get longer — until 30 April. Quarterly TDS statements follow after each quarter.
What replaced Forms 24Q, 26Q and 27Q?
From tax year 2026-27 the Income-tax Rules, 2026 renumbered the quarterly TDS statements: Form 138 replaces 24Q (salaries), Form 140 replaces 26Q (other payments to residents) and Form 144 replaces 27Q (payments to non-residents). Form 131 replaces Form 16A as the TDS certificate. The quarterly due dates did not change: 31 July, 31 October, 31 January and 31 May.
What happens if I miss a GST due date?
Late fee accrues per day until the return is actually filed, plus interest at 18% per annum on tax paid in cash. Our late fee calculator will size it for a specific delay.
Do these dates ever change?
Yes. The government issues extension notifications fairly regularly, particularly around portal outages and year-end. Treat this calendar as the standing rule and check the GST portal for any notification covering the specific period before you rely on a date.
