GST Return Types: All 14 GST Forms Explained (2026)

GST Return Types in India: All 14 GST Forms and What Each One Does (2026 Guide)

Getting a GSTIN is only the first step. Once you are registered, GST return filing becomes a regular part of running the business. Many new traders ask how many types of GST returns there are, and there is no single fixed number.

The count changes depending on what you include. Along with the main returns, the GST system has statements, payment challans and supporting forms. Some forms are returns in the strict sense. Others, like CMP-08, are statement-cum-challans, and GSTR-1 is an outward supplies statement. In practice, people treat all of them as “GST returns.”

You also won’t file all of them. Your registration type decides your forms. A regular taxpayer, a composition dealer, an e-commerce operator, a government deductor and a foreign service provider each file a different set. This guide groups the 14 most important GST forms into four categories so you can find your own set quickly.

Category 1: GST return forms for regular taxpayers

Most ordinary businesses fall here. If you charge GST on sales and claim input tax credit (ITC) on purchases, three forms make up your routine.

GSTR-1: Outward supplies (sales) statement

GSTR-1 is not a tax return in the usual sense. It is a statement of your outward supplies. You report every sale, invoice by invoice, along with credit notes and debit notes.

All regular taxpayers file it. Monthly filers submit it by the 11th of the following month. Businesses on the QRMP scheme file it quarterly, by the 13th of the month after the quarter ends. QRMP, short for Quarterly Return Monthly Payment, is open to businesses with turnover up to ₹5 crore and lets them file GSTR-1 and GSTR-3B quarterly instead of monthly.

GSTR-1 matters beyond your own books. The invoices you upload flow into your buyer’s auto-drafted statement, and that is what lets the buyer claim ITC. A late or wrong GSTR-1 can hold up your customers’ credit and damage the relationship.

GSTR-1A: Correcting the current month’s GSTR-1

GSTR-1A is an amendment form that sits between GSTR-1 and GSTR-3B. It was introduced by Notification No. 12/2024-Central Tax on 10 July 2024, and it is available once per period, up to the point you file that period’s GSTR-3B.

You use it to add an invoice you missed or fix a wrong one in the same tax period. A nil GSTR-1A is not available. If you save a GSTR-1A and don’t file it, the system blocks your GSTR-3B for that period.

Its importance has grown sharply since 2025, which is covered in the recent updates section below.

GSTR-3B: Summary return and tax payment

GSTR-3B is the main self-assessed summary return. You report total sales on which tax is due, total purchases on which you claim ITC, and the net tax you must pay. The payment itself is made through this form.

Monthly filers file by the 20th of the next month. Quarterly QRMP filers file by the 22nd or 24th of the month after the quarter, depending on their state category. QRMP taxpayers also pay tax monthly through the PMT-06 challan, due on the 25th.

You must file GSTR-3B even when there were no sales. A “Nil return” is compulsory, and skipping it still attracts a late fee.

Category 2: GST forms for small and special taxpayers

Some business models get their own, simpler forms so they are spared the monthly routine.

CMP-08: Quarterly statement for composition dealers

Composition dealers don’t file GSTR-1 or GSTR-3B. They pay tax through CMP-08, a statement-cum-challan. It reports turnover and pays tax at the composition rate, and it is due by the 18th of the month after each quarter.

The tax is a fixed percentage of turnover. The rates are 1% for traders and manufacturers, 5% for restaurants and 6% for other eligible services.

GSTR-4: Annual return for composition dealers

Composition taxpayers file one annual return, GSTR-4. It brings together the year’s turnover and the tax already paid through CMP-08.

The due date has changed. Many guides still say 30 April. From FY 2024-25 onwards, the due date is 30 June of the following financial year, so FY 2025-26 closed on 30 June 2026. Filing CMP-08 does not replace GSTR-4. Both are required.

GSTR-5: Return for non-resident taxable persons

GSTR-5 is for foreign individuals or companies with no permanent place of business in India who trade here temporarily, such as someone selling goods at an exhibition. It is due on the 20th of the next month, or within seven days after the registration expires, whichever is earlier.

GSTR-5A: Return for foreign online service providers (OIDAR)

GSTR-5A is for overseas companies that supply online information and database access or retrieval services to Indian customers. Streaming, software and cloud services are typical examples. It is due by the 20th of every month, and these suppliers report GST on their Indian earnings.

A caution on online gaming. Online money gaming appears in older guides alongside these services. The Promotion and Regulation of Online Gaming Act, 2025 and its 2026 Rules, in force from 1 May 2026, prohibit online money gaming. Ordinary online services such as streaming and SaaS are not affected.

GSTR-6: Return for input service distributors (ISD)

GSTR-6 is filed by the head office of a business that receives common service invoices and distributes the ITC to branches in different states. It is due by the 13th of every month.

ISD registration used to be optional. From 1 April 2025, routing credit on common input services through the ISD mechanism became mandatory. A head office that skipped ISD earlier should check its position.

Category 3: GST TDS and TCS forms

GST has two source-based mechanisms to track transactions and limit evasion: tax deducted at source (TDS) and tax collected at source (TCS).

GSTR-7: TDS return for government deductors

When a government department, local authority or other notified person pays a supplier under a contract worth more than ₹2.5 lakh, it deducts 2% GST as TDS. The deductors include government departments and establishments, local authorities, government agencies and other notified persons. Details of the deduction go into GSTR-7, due by the 10th of the following month.

On a ₹20 lakh contract, the deduction is ₹40,000. The supplier then claims that amount as credit in its own ledger.

GSTR-8: TCS statement for e-commerce operators

An e-commerce operator that collects payment on behalf of sellers must collect TCS before passing the money on. GSTR-8 reports the month’s sales through the platform and the TCS collected. It is due by the 10th of the next month.

Many older articles quote a 1% rate. The current rate is 0.5% in total (0.25% CGST plus 0.25% SGST, or 0.5% IGST), effective from 10 July 2024. On ₹10 lakh of net taxable sales through the platform, that is ₹5,000.

Category 4: Annual, reconciliation and closing forms

These forms close out the year or the business.

GSTR-9: Annual return for regular taxpayers

GSTR-9 is the year’s report card. It consolidates the data from your GSTR-1 and GSTR-3B filings into one annual statement. It is due by 31 December after the financial year ends, so FY 2025-26 is due on 31 December 2026. Filing is optional up to ₹2 crore of turnover and mandatory above it.

GSTR-9C: Reconciliation statement

GSTR-9C matches your audited financial statements against your GST returns. It applies to taxpayers with turnover above ₹5 crore. It is self-certified by the taxpayer. The deadline is the same as GSTR-9, 31 December.

GSTR-10: Final return

GSTR-10 is a “final return,” not an annual one. You file it when you cancel or surrender your GST registration, typically because you are closing the business. It declares closing stock and any tax payable on it. It must be filed within three months of the cancellation date or the cancellation order, whichever is later.

GSTR-11: Statement for UIN holders

Embassies and UN bodies don’t charge GST, so they don’t pay it as taxpayers. They hold a Unique Identification Number (UIN) and use GSTR-11 to list their inward purchases so they can claim a refund of the GST they paid. A refund not claimed within six months lapses.

What changed recently in GST return filing

Several changes in 2025 and 2026 affect how you file.

GSTR-3B liability is locked. From the July 2025 tax period, the tax liability auto-populated in GSTR-3B from GSTR-1, GSTR-1A and IFF cannot be edited. Whatever you report in GSTR-1 is what you pay. If it’s wrong, you fix it in GSTR-1A before filing GSTR-3B. After that, only a later GSTR-1 can amend it.

Credit now depends on the Invoice Management System (IMS). The IMS, launched in 2024, lets you accept, reject or keep invoices pending before your credit statement is generated. Reconciliation has moved to before filing, not after.

Old returns can no longer be filed. Since the July 2025 tax period, the portal blocks filing of GSTR-1, GSTR-3B, GSTR-4 and GSTR-9 once three years have passed from the original due date.

GSTR-4 now falls on 30 June. The old 30 April date no longer applies.

TCS is 0.5%, not 1%.

Late fees and interest

A missed deadline costs money even when there is nothing to pay. The late fee for GSTR-1 and GSTR-3B is ₹50 per day (₹25 CGST plus ₹25 SGST), or ₹20 per day for a nil return. The maximum depends on turnover. It is ₹2,000 up to ₹1.5 crore, ₹5,000 up to ₹5 crore and ₹10,000 above that, with ₹500 for nil returns. Interest on unpaid tax runs at 18% per year from the due date.

Late fees are separate from interest. Interest applies only if tax was paid late.

FAQs on GST return types

How many types of GST returns are there?

There is no fixed number. This guide covers 14 important forms, but the right set for you depends on your registration type.

Which GST returns does a small trader usually file?

A regular taxpayer files GSTR-1, GSTR-3B and the annual return GSTR-9. A composition dealer files CMP-08 every quarter and GSTR-4 once a year.

Is a nil return mandatory?

Yes. Even with no sales in the month, a nil GSTR-3B is required, and a late nil return still attracts a ₹20-per-day fee.

What is the difference between GSTR-1 and GSTR-3B?

GSTR-1 lists your sales invoice by invoice. GSTR-3B summarises sales and purchases, calculates net tax and is where you pay.

Is GSTR-9 compulsory for small businesses?

It is optional up to ₹2 crore of turnover. Above that, it is mandatory.

Can I amend GSTR-3B after filing it?

No. Correct the same period in GSTR-1A before you file GSTR-3B. Once filed, amendments go through a later GSTR-1.

Which returns will you actually file?

Once you know your registration type, most of this list falls away. A regular taxpayer lives in GSTR-1 and GSTR-3B, with GSTR-1A as the safety net and GSTR-9 at the year’s end. A composition dealer works with CMP-08 and GSTR-4. The remaining forms belong to specific roles such as deductors, collectors, distributors and foreign suppliers.

The habit that saves the most money is simple. Check your GSTR-1 and your purchase invoices before the 11th, not after the 20th. With liability now locked from GSTR-1, that early check is where most return errors get caught. Confirm exact dates on the GST portal each year, since due dates can be extended by notification.
