Why? Because unlike most GST forms, GSTR-4 cannot be revised once filed. One mistake, and it's locked in forever.

This guide walks you through everything you need to know about GSTR-4 in 2026. We'll cover what it is, who needs to file it, the exact steps to file it, the penalties you'll face if you're late, and most importantly — how to avoid the five costly mistakes that catch thousands of composition dealers every single year.

Basics

What exactly is GSTR-4?

GSTR-4 is your annual tax return under the GST Composition Scheme. Think of it as the year-end report card for your business, it tells the government everything about your business activity and tax liability for the financial year.

Throughout the year, you're paying tax quarterly using Form CMP-08. GSTR-4 is where all those quarterly payments come together. It's your comprehensive summary of:

All outward supplies — everything you sold during the year
All inward supplies — everything you purchased
Services you imported from overseas
Supplies attracting Reverse Charge Mechanism (RCM) — specific purchases where you, not your supplier, pay the tax

Before FY 2019–20, composition dealers had to file multiple quarterly returns. It was a compliance nightmare. The government listened, simplified the system, and introduced the current structure: quarterly CMP-08 payments plus one annual GSTR-4 filing.

This change was designed specifically for businesses like yours, to reduce the compliance burden while keeping the government fully informed.

Here's the critical part: Once you file GSTR-4, you cannot revise it. Not if you spot an error. Not if you realize you missed an invoice. It's final. This is why accuracy from the start isn't just good practice, it's essential.

Eligibility

Who Actually Needs to File GSTR-4 in 2026?

Not every GST-registered business files GSTR-4. It's specifically for Composition Scheme dealers.

If you're registered under the Composition Scheme, you need to file GSTR-4 if:

You've been under the Composition Scheme since registration and never opted out
You opted into the scheme before the financial year started
You opted in during the year but later switched out (yes, even if you're no longer on the scheme)

Who qualifies for the Composition Scheme?

The Composition Scheme is available to manufacturers, traders, and restaurant owners (excluding alcohol establishments) with annual turnover up to ₹1.5 crore in regular states and ₹75 lakh in special category states. Service providers under the special composition scheme can use it with a ₹50 lakh turnover limit.

Who doesn't need to file GSTR-4?

If you're a regular GST taxpayer (not on Composition Scheme), non-resident, input service distributor, casual taxpayer, or handling TDS/TCS collections, you file different returns — not GSTR-4.

Here's something many dealers get wrong: If your turnover was absolutely zero during the year, zero sales, zero purchases, you still must file a Nil GSTR-4. Not filing it triggers late fees and flags your GSTIN for compliance issues with the GST department. It's a small step that prevents a big headache.

Due Date

The 30th June 2026 Deadline — Mark Your Calendar

The GSTR-4 due date for FY 2025–26 is 30th June 2026.

This is important because many dealers still think the old deadline of 30th April applies. It doesn't. Following the 53rd GST Council meeting, the government extended the deadline by two months via CGST Notification 12/2024, effective from FY 2024–25 onwards.

FY 2023–24

30th April 2024

FY 2024–25

30th June 2025

FY 2025–26

30th June 2026

Those extra two months give you breathing room to compile records and file accurately. But — and this is important — you cannot file beyond three years from the original due date. So while the deadline is extended, it's not indefinite.

The bottom line? File well before 30th June 2026. Don't wait until last week. Last-minute rushes lead to errors, and errors in GSTR-4 cannot be fixed.

GSTR-4 vs CMP-08

GSTR-4 vs CMP-08 — The Confusion Everyone Has

Here's one of the most confusing parts of composition scheme compliance: the relationship between GSTR-4 and CMP-08.

Many dealers ask: "Do I really need both? Aren't they the same thing?"

No. They're completely different, and both are mandatory.

CMP-08

Your quarterly advance tax payment challan. Every three months, you calculate the tax on your supplies and pay it. It's a payment statement, not a compliance return.

CMP-08 = Quarterly tax you paid

GSTR-4

Your annual compliance return. It's the official report to the GST department summarizing your entire year's business activity.

GSTR-4 = Annual summary of everything + final settlement

Here's the key relationship: The data from all four quarters of CMP-08 automatically populates into GSTR-4. So if you filed CMP-08 incorrectly in Q1, that error carries into GSTR-4. This is why reconciliation before annual filing is so critical.

Both are mandatory. You cannot file GSTR-4 without having filed all four CMP-08 statements first. The GST portal simply won't let you, the "File" button stays disabled.

Form Structure

What Goes Into GSTR-4? The Nine Tables Explained

GSTR-4 consists of nine tables. Let's break down what each one requires:

Tables 1–3

Auto-Populated Information

Your GSTIN, legal name, trade name, and aggregate turnover from the previous year automatically fill here. The GST portal pulls this directly from its database. You review but don't manually enter anything.

Table 4

Inward Supplies (Including Reverse Charge)

This is where you manually list everything you bought during the year:

Supplies from registered suppliers (regular purchases)
Supplies from registered suppliers where you pay tax (RCM)
Supplies from unregistered dealers
Services imported from overseas

If you're unclear about which category applies, this is where mistakes happen. Misclassifying a purchase can trigger department notices.

Table 5

Self-Assessed Tax Liability

This auto-fills from your quarterly CMP-08 filings. It consolidates the tax you already paid across all four quarters. You review it for accuracy against your records.

Table 6

Tax Rate-Wise Outward and RCM Supply Details

You enter the total sales made at each tax rate (5%, 12%, 18%, 28%, and 0%). The system automatically calculates IGST, CGST, SGST/UTGST, and cess. This section is crucial because it determines your total tax liability for the year.

Table 7

TDS/TCS Credit

If a buyer deducted tax from your invoice (TDS), or if you received tax collected by e-commerce operators (TCS), you enter those details here. It's straightforward but easy to overlook.

Table 8

Tax Settlement

This is the final settlement table. It shows total tax payable for the year, tax you already paid via CMP-08, any remaining balance (amount still owed), and interest and late fees (if applicable). If there's a balance, you must clear it through the Electronic Cash Ledger before you can file. The portal won't let you submit if money is outstanding.

Table 9

Refund Claim

If you overpaid through CMP-08 throughout the year, you can claim a refund here. This is relatively rare for composition dealers but important when it applies.

Verification

Digital Authentication

Finally, you digitally sign the return using a DSC (Digital Signature Certificate) or EVC (Electronic Verification Code) to confirm everything is accurate.

Process

How to File GSTR-4 Online: Step-by-Step

Filing GSTR-4 online is straightforward when you have your records organized. Here's the process:

Step 1

Log Into the GST Portal

Go to www.gst.gov.in and log in with your GSTIN credentials. Make sure you have DSC or EVC already set up.

Step 2

Navigate to Annual Return

From your dashboard, go to Services → Returns → Annual Return. You'll see an option for Form GSTR-4.

Step 3

Select Your Financial Year

Choose FY 2025–26 and click "Prepare Online". Read the instructions carefully, they highlight important rules specific to this filing year.

Step 4

Fill the Tables

Tables 1–3 and 5 are auto-filled. You manually complete Tables 4, 6, 7, 8, and 9 based on your records. Take your time here. Cross-check every entry.

Step 5

Download and Verify

Download the GSTR-4 summary as a PDF or Excel file. Open it and cross-verify every number against your accounting books. This step is non-negotiable because you cannot revise after filing.

Step 6

Submit

Click "File GSTR-4". A confirmation warning appears. Click "Yes" to proceed. This is your last chance to back out, make sure everything is correct.

Step 7

Authenticate Your Filing

You'll be asked to authenticate using:

DSC (Digital Signature Certificate) — for companies and LLPs
EVC (Electronic Verification Code) — for proprietors and partnerships (an OTP is sent to your registered phone)

Step 8

Receive Your ARN

Once successfully filed, the GST portal generates an Application Reference Number (ARN). You'll get SMS and email confirmations to your registered contact details. Your GSTIN status changes to "Filed". Keep the ARN safe. It's your proof that GSTR-4 was filed.

Late Fee

Late Fees and Penalties: The 2026 Cost of Missing the Deadline

File late, and you pay. The late fee structure is straightforward but costly:

Return with Tax Liability

₹50/day (₹25 CGST + ₹25 SGST)

Maximum cap: ₹2,000

Nil Return

₹50/day

Maximum cap: ₹500

These fees are mandatory. You pay them through the Electronic Cash Ledger before the portal allows you to file. The "File" button stays grayed out until the fees are paid.

Here's what this means: If you file 10 days late with a regular return, you owe ₹500 in late fees. If you file 40 days late, you hit the ₹2,000 cap. Either way, it's money out of your pocket for something that was entirely preventable. The good news? These caps are significantly lower than the old ₹5,000 maximum. But even ₹2,000 is money you could keep. Filing before 30th June 2026 keeps your compliance record clean and your cash in your business.

Common Mistakes

Five Costly Mistakes That Composition Dealers Make Every Year

We see these mistakes repeatedly. Here's how to avoid them:

Not Reconciling CMP-08 Before Filing GSTR-4

Your quarterly CMP-08 forms auto-populate into GSTR-4. If there are errors in your CMP-08 data, they carry straight through to GSTR-4. Before filing annually, sit down with your CA or bookkeeper and verify each quarter's CMP-08 against your actual records. Catch errors now, not after filing.

Skipping the Nil Return

"I had no business this year, so I don't need to file GSTR-4." Wrong. Nil GSTR-4 is still mandatory. Many dealers assume they can skip it if there was no activity, this triggers late fees, compliance notices, and blocks your GSTIN from future filings. File Nil if needed. It takes 10 minutes.

Misclassifying Inward Supplies

RCM purchases, unregistered dealer purchases, and imported services each go in specific sub-tables within Table 4. Putting them in the wrong place triggers department notices and questions you don't want to answer. If you're unsure, ask your CA. Getting it right saves months of back-and-forth later.

Missing Imported Services

Service-based businesses often overlook this. If you paid for any overseas service, software subscriptions, consulting, cloud services, design work, anything from abroad, those are reportable inward supplies under Reverse Charge Mechanism. Forgetting them is a red flag to the department.

Thinking You Can Fix It Later

This is the biggest mistake of all. GSTR-4 has no revision mechanism. Once you hit "File" and get your ARN, the data is locked. There's no "Amended GSTR-4". You cannot go back and fix anything. This is why careful review before filing isn't optional, it's mandatory.
