Miss a GST payment and three things follow, in order: interest at 18% per annum from the day after the due date, a late fee of Rs 50 per day on delayed returns, and a penalty of 10% to 100% of the tax due (as of 2026). Jail is real but rare: prosecution generally begins only above Rs 2 crore of evasion.
That is the short answer. The longer answer depends on whether you were late, careless, or deliberate, and the law treats those three very differently. Here is the full ladder, from a missed deadline to a search of your premises, with the sections of the CGST Act that back each step.
What actually happens first when you miss a GST payment?
Interest starts running immediately: 18% per annum on the unpaid tax, counted from the day after the due date, under Section 50(1) of the CGST Act (as of 2026). Nobody sends you a warning first. The clock simply starts.
On top of interest, a delayed return attracts a late fee of Rs 50 per day (Rs 25 CGST plus Rs 25 SGST), or Rs 20 per day if it is a nil return, as of 2026. The late fee is capped based on your turnover slab; check the current CBIC notification for the exact ceiling that applies to you.
Two more things worth knowing:
The GST Network flags non-filers automatically. Notices land in your portal inbox and on your registered email, not by post, so "I never received it" is a weak defence. And since the 2022 amendment to Section 50, interest on wrongly availed input tax credit applies only once you actually utilise that credit, also at 18%.
Who has to pay GST in the first place?
As of 2026, GST registration is mandatory once annual aggregate turnover crosses Rs 40 lakh for businesses supplying only goods (in the 20-plus states that adopted the higher limit, including Maharashtra, Gujarat, Karnataka and Tamil Nadu), and Rs 20 lakh for service providers. In special category states the service threshold is Rs 10 lakh. These limits come from Section 22 of the CGST Act and have held since 2019.
If you sell across state lines or through e-commerce platforms, registration can be mandatory regardless of turnover. Smaller businesses can also opt for the composition scheme, which trades a flat tax rate for lighter compliance; eligibility limits change by notification, so confirm the current ceiling on the GST portal before opting in.

Which offences under GST attract penalties?
Section 122(1) of the CGST Act lists 21 specific offences, and they cluster into five themes (as of 2026):
- Invoice fraud: supplying goods without an invoice, issuing an invoice without any supply, or claiming input tax credit on fake invoices. Read the GST invoice format and rules if your paperwork is shaky, because this theme carries the harshest treatment.
- Keeping the government's money: collecting GST from customers and not depositing it within 3 months (Section 122(1)(iii)).
- TDS failures: not deducting GST TDS, deducting short, or not depositing what you deducted. The penalty equals the TDS amount involved, minimum Rs 10,000, under Section 122(1)(v). There is no grace period here.
- Registration failures: doing taxable business without registering, or giving false particulars at registration.
- Records and obstruction: suppressing turnover, falsifying accounts, obstructing an officer, transporting goods without documents.
Two additions since 2021 widen the net. Section 122(1A) penalises people who benefit from fake-invoice transactions even if they never filed a return themselves, and Section 122(1B) (from 1 October 2023) makes e-commerce operators liable for unregistered sellers on their platforms.
One more thing owners often miss: when a company commits an offence, Section 137 makes the person in charge of the business deemed guilty along with it. Directors, managers and secretaries are liable where there was consent, connivance or negligence; for a firm or LLP it is the partner, for an HUF the karta, for a trust the managing trustee. The defence is proving the offence happened without your knowledge or despite due diligence.
How big are the penalties for not paying GST?
The core rule as of 2026: an honest short payment costs 10% of the tax due (minimum Rs 10,000), while fraud, wilful misstatement or suppression costs 100% of the tax due (minimum Rs 10,000), under Section 122(2). For tax periods from FY 2024-25 onwards, demands run under the new Section 74A, but the rates are the same.
| What happened | What it costs (as of 2026) | Where the law says so |
|---|---|---|
| Paid or filed late, honest delay | 18% p.a. interest + Rs 50/day late fee (Rs 20/day for nil returns) | Sec 50(1) CGST Act |
| Short-paid tax, no fraud | 10% of tax due, min Rs 10,000 | Sec 122(2)(a) / Sec 74A |
| Fraud, wilful suppression | 100% of tax due, min Rs 10,000 | Sec 122(2)(b) / Sec 74A |
| Aided or abetted an offence, ignored a summons, invoice failures (as a third party) | Up to Rs 25,000 | Sec 122(3) |
| Evasion above Rs 2 crore | Prosecution on top of penalty | Sec 132, Finance Act 2023 |
Before any penalty is imposed, the officer must issue a show-cause notice, hear you out, and record the nature of the breach in the order. Penalties skipped without this process can be struck down on appeal. Section 126 also bars penalties for minor breaches: tax involved under Rs 5,000 (as of 2026), or documentation slips that are easily corrected.
These are legal provisions, not advice for your specific case; run any actual notice past your CA.
Can you go to jail for GST evasion?
Yes, but only at serious scale. As of 2026, Section 132 sets three imprisonment slabs by amount of tax evaded: up to 1 year for Rs 1 crore to Rs 2 crore, up to 3 years for Rs 2 crore to Rs 5 crore, and up to 5 years plus fine above Rs 5 crore. Offences in that top band, under clauses (a) to (d), are cognizable and non-bailable.
The bigger story is what changed. The Finance Act 2023 raised the practical prosecution floor from Rs 1 crore to Rs 2 crore of tax evaded, with one exception: issuing invoices without any supply, which stays prosecutable at the lower threshold because fake invoicing is the fraud the department chases hardest. The same Act decriminalised three offences entirely: obstructing an officer, tampering with evidence, and failure to supply information. Those now attract monetary penalties, not criminal charges.
Some guardrails remain in your favour. No prosecution can be launched without the Commissioner's prior sanction under Section 132(6). But a repeat conviction carries imprisonment up to 5 years regardless of amount, so a second offence is a different game.
When can officers inspect, search or seize your business?
Not on a whim. Under Section 67, an officer of the rank of Joint Commissioner or above must authorise any inspection, search or seizure in writing, and only on specific grounds: reason to believe you suppressed transactions or stock, claimed excess input tax credit, or that a transporter or warehouse is holding untaxed goods (as of 2026).
In practice, seizure means officers can take away goods, documents, books and devices. The law then binds them to timelines: documents not relied on for the notice must be returned within 30 days of the notice being issued, and seized goods must be released if no notice is served within 6 months (extendable by another 6). If a search happens, note down what was taken and ask for the authorisation; both matter at the appeal stage.
How do you appeal a GST demand or penalty?
The appeal ladder has four rungs: the Appellate Authority, the GST Appellate Tribunal, the High Court, and the Supreme Court. The big change since the early GST years is that the tribunal now actually functions. GSTAT has its Principal Bench in Delhi and benches in over 40 cities, with e-filing live and hearings running under the GSTAT Procedure Rules 2025 (as of 2026, per gstat.gov.in). For years, taxpayers who lost at the first appeal had nowhere to go except a writ in the High Court. That bottleneck is gone.
Filing deadlines are tight. You get 3 months from the date the order is communicated to appeal to the First Appellate Authority under Section 107(1), and the authority can condone a delay of at most 1 more month on sufficient cause. The department gets 6 months for its own review applications and pays no pre-deposit or fee.
For you, appealing has a price, though a smaller one than before. As of 2026 the pre-deposit is: 100% of the tax, interest and penalty you admit, plus 10% of the disputed tax, capped at Rs 20 crore of central tax. Going up to the tribunal costs an additional 10% of the disputed tax, same cap. The Finance (No. 2) Act 2024 cut the tribunal rate from 20% to 10% and lowered the caps from 1 November 2024, so disputing a demand is materially cheaper than it was in 2021. A 25% pre-deposit exists only in one niche: penalty appeals in e-way bill detention cases under Section 129(3).
Four kinds of orders cannot be appealed at all, under Section 121: transfer of proceedings between officers, seizure or retention of books and records, sanction of prosecution, and orders under Section 80 allowing payment of dues in instalments.
You do not have to appear yourself. Section 116 lets an authorised representative act for you: a relative or regular employee, an advocate, a CA, cost accountant or company secretary holding a certificate of practice, a retired tax department officer, or a GST practitioner.
How do you stay out of trouble?
File every return on time, even when it is nil, because the Rs 20-per-day nil late fee and the non-filer flag apply whether or not you owed anything. That single habit removes most of the risk described above.
Beyond that, reconcile your books with your filed returns every month rather than at year-end, so a mismatch surfaces as a correction instead of a show-cause notice. Keep invoices clean and sequential; almost every serious GST case starts with invoice trouble. And do not bank on mercy. The Act has no first-offender exemption; the only built-in relief is Section 126 for minor breaches under Rs 5,000. Amnesty comes in windows: the Section 128A scheme waived interest and penalty on non-fraud demands for FY 2017-18 to 2019-20 if the full tax was paid on time, but that window closed in 2025. As of August 2026, no waiver scheme is open, so the price of delay is the full statutory one.
FAQs
What is the penalty for not paying GST in India?
As of 2026, a non-fraudulent short payment attracts a penalty of 10% of the tax due (minimum Rs 10,000), while fraud or wilful suppression attracts 100% of the tax due (minimum Rs 10,000), under Section 122 of the CGST Act. Interest at 18% per annum applies in both cases.
Can you go to jail for not paying GST?
Only for large-scale evasion. Since the Finance Act 2023, prosecution is generally launched only above Rs 2 crore of tax evaded (except fake invoicing). Imprisonment runs up to 3 years for Rs 2 crore to Rs 5 crore and up to 5 years above Rs 5 crore, where offences are cognizable and non-bailable.
What is the interest rate for late GST payment in 2026?
18% per annum on the unpaid tax, from the day after the due date, under Section 50(1) of the CGST Act. Delayed returns also attract a late fee of Rs 50 per day (Rs 20 per day for nil returns).
How long do I have to appeal a GST demand order?
3 months from communication of the order, to the First Appellate Authority under Section 107. The authority can condone a delay of up to 1 more month on sufficient cause. The pre-deposit is 100% of admitted dues plus 10% of the disputed tax (as of 2026).
Is there any leniency for first-time GST offenders?
No. The CGST Act has no first-offender exemption. The only standing relief is Section 126, which bars penalties for minor breaches involving tax under Rs 5,000 or easily rectifiable documentation errors. Repeat conviction actually increases punishment under Section 132(2).
