Your GST Late Fee Is Capped by Turnover, Not by How Many Months You Are Late
The daily late fee for GSTR-1 and GSTR-3B is Rs 50, and it does not double after three months. What changes with delay is not the rate but which of three separate charges you have triggered, and whether the return is still filable at all.
Most people searching for GST late fees want one number. There isn’t one, and the reason matters. Filing late triggers up to three completely separate charges that live in different sections of the law, are calculated on different bases, and are paid in different ways. Treating them as a single penalty is how businesses end up either over-providing for a small delay or being blindsided by an interest bill nobody capped.
Quick Summary
The late fee for a delayed GSTR-1 or GSTR-3B is Rs 50 per day, split as Rs 25 CGST and Rs 25 SGST, or Rs 20 per day for a nil return. The maximum is not a single figure: it is Rs 500 for nil returns, Rs 2,000 for turnover up to Rs 1.5 crore, Rs 5,000 for Rs 1.5 crore to Rs 5 crore, and Rs 10,000 above Rs 5 crore, under Notifications 19/2021 and 20/2021. Separately, interest runs at 18 percent a year under Section 50 on tax paid late, and it is not capped at all. The Rs 10,000 or 10 percent figure people quote comes from Section 73(9) and applies to a demand order, not automatically to a late return.
Three charges, three sections, three different behaviours
The single most useful thing you can learn about GST penalties is that they are not one charge. Once you can name which of the three you are looking at, the numbers stop being confusing.
The late fee accrues by the day and stops at a ceiling. The interest accrues by the day and never stops until the tax is paid. The Section 73 penalty is not charged by the portal at all; it appears only when an officer issues a demand for tax short-paid or ITC wrongly availed, and even then it is reduced or waived if you pay before the notice or within thirty days of it. Conflating the third with the first is the single most common error in circulating compliance material.
What we know, straight from the notifications
These are the operative figures, each traceable to a specific provision rather than to a summary chart.
What the circulating chart gets right, and what it gets wrong
The graphic that prompted this article is not worthless. Its daily rate, its CGST and SGST split, and its interest figure are all correct. Three other elements are not, and each error points in a direction that would cost a reader money or confidence.
| What the chart says | What the law says | Verdict | Why it matters |
|---|---|---|---|
| Rs 50 per day, split Rs 25 CGST and Rs 25 SGST | Same, under Section 47 as reduced by notification | Correct | This is the figure the portal computes |
| Interest at 18 percent a year on delayed tax | Same, under Section 50 | Correct | Note it is on net cash liability under Rule 88B |
| Late fee applies even with no tax liability | Same, but at the reduced nil rate of Rs 20 per day | Correct but incomplete | The chart omits the nil rate entirely |
| Rs 100 per day after three months | No such escalation. The rate stays at Rs 50 | Incorrect | Overstates a long delay by double |
| Maximum of Rs 5,000, or Rs 10,000 after three months | Cap is set by turnover, not by delay | Incorrect | A small business is capped at Rs 2,000, not Rs 5,000 |
| Additional penalty of Rs 10,000 or 10 percent of tax | Section 73(9), applies to a demand order | Misapplied | Not charged automatically for filing late |
Where the Rs 100 per day figure comes from
It is not invented. The original text of Section 47 of the CGST Act does prescribe Rs 100 per day per Act, which is Rs 200 a day combined, subject to Rs 5,000. That statutory rate was reduced by notification to Rs 25 per Act, and the caps were rationalised by Notifications 19/2021 and 20/2021 into the turnover slabs used today. So the chart is quoting the unamended statute rather than the operative rate. If you are reading any GST material that still shows Rs 100 or Rs 200 a day for GSTR-3B, that is the tell that it predates the rationalisation.
The direction of each error is worth noting, because it is not random. Every one of the three mistakes makes late filing look more expensive and more punitive than it is. That may seem harmless, even useful, if the aim is to frighten people into filing on time. It is not harmless in practice. A small trader who believes a four-month delay will cost Rs 20,000 may conclude the return is unaffordable this month and defer it again, when the actual exposure was Rs 2,000 of capped fee plus interest on whatever tax was due. Overstating a penalty produces the same paralysis as understating a deadline.
The cap that actually applies to you
This is the part that changes the answer most, and it depends on a number that has nothing to do with your delay: your aggregate annual turnover in the preceding financial year.
The practical consequence is that a small trader who is six months late on one return does not owe Rs 10,000. At Rs 50 a day for roughly 180 days the raw figure would be Rs 9,000, but the Rs 2,000 cap intervenes long before that. Meanwhile a company above Rs 5 crore turnover reaches its Rs 10,000 ceiling after 200 days and stops there too. The cap is a genuine relief, and it is the single most misreported feature of the regime.
Worked examples, because the arithmetic is the answer
Three businesses, three very different bills
The small shop. Turnover Rs 60 lakh, GSTR-1 filed 15 days late. Fifteen days times Rs 50 gives Rs 750, well inside the Rs 2,000 cap. Paid as Rs 375 CGST plus Rs 375 SGST. No interest, because GSTR-1 carries no tax payment.
The dormant registration. No supplies for the month, GSTR-3B filed 60 days late. Sixty days times Rs 20 gives Rs 1,200, but the nil cap is Rs 500, so the bill is Rs 500. This is the case people are most surprised by, because they assume no activity means no fee.
The mid-sized trader. Turnover Rs 2 crore, GSTR-3B for a month filed 97 days late, with net cash tax of Rs 45,000. Late fee is 97 times Rs 50, or Rs 4,850, inside the Rs 5,000 cap. Interest is Rs 45,000 times 18 percent times 97 divided by 365, or about Rs 2,153. Total roughly Rs 7,003. Under the circulating chart’s method the same business would have been told to expect Rs 10,000 of late fee plus another Rs 10,000 of penalty.
Notice which component grows without limit. In the third example the late fee was capped after 100 days but the interest kept running, and it will keep running until the cash is actually deposited. For a business with a large tax liability and a long delay, interest overtakes the late fee quickly and becomes the dominant cost.
The consequences that cost more than the fee
Focusing on the rupee amount understates the problem. The operational blocks triggered by a missed return are frequently worse than the charge itself, and they escalate on a schedule.
The buyer-side cost nobody puts in the chart
When your GSTR-1 is blocked, your customers cannot see your invoices in their GSTR-2B, and under current rules they cannot claim input tax credit that GSTR-2B does not support. A single missed GSTR-3B therefore transmits a cash-flow problem to every business you sell to, in the same month. For B2B suppliers this is the real penalty, and it does not appear in any section of the Act. It appears in the next procurement review.

What is still unclear, and worth checking before you rely on it
Two commonly repeated claims could not be verified against a notification, and one widely announced change has a moving date.
How to clear a backlog without making it worse
If you are reading this because several returns are already pending, the order in which you file matters more than the speed. GST returns are sequential, and attempting them out of order simply produces portal errors.
- List every pending period by GSTIN, oldest first. Check each against the three-year bar before anything else. A period approaching that line is the only genuine emergency in the list, because it is the only cost that cannot be paid off later.
- File GSTR-3B in chronological order. The portal will not let you skip a month, and Rule 59(6) keeps GSTR-1 blocked until the preceding GSTR-3B is in. Working backwards from the most recent month is the most common wasted afternoon in Indian accounting.
- Fund the cash ledger before you start. Late fee and interest cannot be paid from input tax credit, and the return will not submit until the exact cash is sitting in the CGST and SGST ledgers. Compute the total for all pending months first and deposit once.
- Clear reverse-charge dues and negative credit balances. Since January 2026 these are validated at submission. A pending reverse-charge liability from an earlier month will block the current filing regardless of how correct the rest of the return is.
- Reconcile with GSTR-2B before claiming credit, not after. Auto-populated liability in GSTR-3B has been non-editable since the July 2025 period, so a mistake gets corrected through GSTR-1A rather than adjusted in the summary return.
- Tell your affected buyers. Once your GSTR-1 goes in, their GSTR-2B updates and their credit becomes claimable. Most suppliers skip this step and absorb the relationship damage anyway.
One structural point applies to smaller taxpayers. Businesses on the QRMP scheme file GSTR-1 quarterly through the Invoice Furnishing Facility and GSTR-3B quarterly, which reduces the number of deadlines but concentrates the risk: a single missed quarter creates a three-month gap in your buyers’ credit rather than a one-month gap. The late fee rates and turnover caps are identical either way, so the choice between monthly and quarterly filing is about operational rhythm rather than cost.
Due dates and the fee that applies to each return
| Return | Who files it | Due date | Late fee rate | Maximum |
|---|---|---|---|---|
| GSTR-1 | Monthly filers, outward supplies | 11th of the following month | Rs 50 per day, Rs 20 nil | Rs 2,000 to Rs 10,000 by turnover |
| GSTR-1 under QRMP | Quarterly filers using IFF | 13th of the month after the quarter | Same rates as monthly | Same turnover slabs |
| GSTR-3B | Monthly filers, summary and payment | 20th of the following month | Rs 50 per day, Rs 20 nil | Rs 2,000 to Rs 10,000 by turnover |
| GSTR-3B under QRMP | Quarterly filers | 22nd or 24th by state group | Same rates as monthly | Same turnover slabs |
| GSTR-4 | Composition taxpayers, annual | As notified for the year | Rs 50 per day, Rs 20 nil | Rs 2,000, or Rs 500 for nil |
| GSTR-9 | Annual return | 31 December following the year | Rs 50 to Rs 200 per day by turnover | 0.04 to 0.50 percent of state turnover |
Two things in that table are easy to misread. The GSTR-9 annual return does not follow the same structure at all: since FY 2022-23 its late fee is tiered by turnover at Rs 50, Rs 100 or Rs 200 a day, with the cap expressed as a percentage of turnover in the state rather than as a rupee figure. And GSTR-1 carries no tax payment, so a late GSTR-1 attracts a fee but never interest. Interest attaches to the payment, which happens in GSTR-3B.

Frequently asked questions
What is the late fee for filing GSTR-3B after the due date?
Rs 50 per day of delay, made up of Rs 25 CGST and Rs 25 SGST, or Rs 20 per day for a nil return. The maximum depends on your aggregate annual turnover: Rs 500 for nil returns, Rs 2,000 up to Rs 1.5 crore, Rs 5,000 up to Rs 5 crore and Rs 10,000 above that. Interest at 18 percent a year applies separately on any tax paid late.
Does the GST late fee increase to Rs 100 per day after three months?
No. The daily rate stays at Rs 50 regardless of how long the delay runs. The Rs 100 figure appears in the unamended text of Section 47, which prescribes Rs 100 per day per Act, but that was reduced by notification to Rs 25 per Act. What changes with a longer delay is that you hit your turnover cap, that operational blocks activate, and that interest keeps compounding on the unpaid tax.
Do I have to pay a late fee if I had no sales and no tax?
Yes. The late fee under Section 47 applies to the act of filing late, not to the tax. For a nil return the reduced rate of Rs 20 per day applies, made up of Rs 10 CGST and Rs 10 SGST, and the total is capped at Rs 500 per return regardless of turnover. This catches dormant registrations most often, because owners assume no activity means nothing to file.
Is the Rs 10,000 or 10 percent penalty charged automatically for late filing?
No. That figure comes from Section 73(9) of the CGST Act and applies when a proper officer issues a demand order for tax not paid, short paid or input tax credit wrongly availed in non-fraud cases. It is not levied by the portal for a late return. It can also be reduced or avoided entirely if the tax and interest are paid before a show cause notice or within thirty days of one.
How is interest on late GST payment calculated?
At 18 percent a year under Section 50, computed under Rule 88B on the net cash liability, meaning the portion actually payable from the cash ledger rather than the part settled through input tax credit. For example, Rs 45,000 of net cash tax paid 97 days late attracts about Rs 2,153. Wrongly availed and utilised credit attracts 24 percent instead. Interest has no upper limit.
Can I pay the GST late fee using input tax credit?
No. Late fee and interest must be deposited in the electronic cash ledger and paid in cash through net banking, UPI, NEFT or RTGS, or a debit card. The CGST portion goes to the CGST cash ledger and the SGST portion to the SGST ledger. The portal will not allow the return to be filed until the exact amounts are available in cash, which is a common reason filings stall at the last step.
What happens if a GST return is more than three years overdue?
It can no longer be filed. The portal began enforcing the three-year bar from 1 July 2025 and it was fully live by January 2026, covering GSTR-1, 3B, 4, 5, 6, 7, 8 and 9. Once a period crosses that line, the tax stays unreported and any input tax credit for it is permanently lost, with no waiver route. Businesses with legacy gaps should audit each GSTIN by period rather than waiting.
What else happens besides the fee if I file late?
Three operational blocks. Under Rule 59(6) you cannot file the next GSTR-1 while a previous GSTR-3B is outstanding, which stops your invoices appearing in your buyers’ GSTR-2B and blocks their input tax credit. Under Rule 138E, e-way bill generation stops after two consecutive defaults, halting goods movement. From FY 2025-26, a missed GSTR-9 can also block subsequent monthly returns.
The short version
Read the three charges separately and the confusion disappears. The late fee is Rs 50 a day, or Rs 20 for a nil return, and it stops at a ceiling set by your turnover rather than by your delay: Rs 500, Rs 2,000, Rs 5,000 or Rs 10,000. The interest is 18 percent a year on net cash tax and it never stops until you pay. The Rs 10,000 or 10 percent figure belongs to a demand order and should not be in a late-filing chart at all. What genuinely changed the risk is not the fee schedule but the three-year bar, the ledger validations and the blocking rules, none of which can be settled by writing a cheque later.
