GST Annual Return: Easy, Accurate & Compliant Filing by ASC Group

Filing GST returns throughout the year is only one part of GST compliance. At the end of the financial year, eligible taxpayers may also need to consolidate their GST transactions through GSTR-9, commonly referred to as the GST Annual Return.

The annual return is important because it brings together details of outward supplies, inward supplies, input tax credit (ITC), tax paid and other information reported during the year. More importantly, it gives businesses an opportunity to identify differences between their GST returns, books of accounts and financial records before finalising their annual compliance.

For FY 2024-25 onwards, taxpayers with aggregate turnover up to ₹2 crore are exempt from filing GSTR-9 under Notification No. 15/2025-Central Tax. Taxpayers exceeding the applicable threshold should assess their filing requirements based on their turnover and taxpayer category.

What Is a GST Annual Return?

GSTR-9 is an annual return that consolidates the GST-related information reported by an eligible registered taxpayer during a financial year.

Unlike a monthly or quarterly return, the annual return provides a broader view of the taxpayer's GST position. It may include information relating to:

• Outward taxable and exempt supplies
• Inward supplies
• Input tax credit claimed and reversed
• Tax payable and tax paid
• Credit notes and debit notes
• Amendments to previously reported transactions
• Other relevant GST particulars

The figures available on the GST Portal can make the filing process easier, but businesses should not treat system-populated information as automatically correct. Reconciliation with books and supporting records remains an important part of a sound compliance process.

Who Needs to File GSTR-9?

The requirement depends on the financial year, aggregate turnover and taxpayer category.

For FY 2024-25 onwards, the Government has exempted registered persons whose aggregate turnover is up to ₹2 crore from filing the annual return.

For businesses above this threshold, the applicable requirements should be checked carefully. A simplified overview is:

Aggregate turnover	General GSTR-9 position
Up to ₹2 crore	Exempt for FY 2024-25 onwards, subject to applicable provisions
Above ₹2 crore up to ₹5 crore	GSTR-9 generally applicable
Above ₹5 crore	GSTR-9 generally applicable along with GSTR-9C, subject to applicable provisions

Certain taxpayers, including specific categories such as input service distributors, casual taxable persons and non-resident taxable persons, may be subject to different provisions.

Therefore, turnover should not be the only consideration when determining annual-return applicability.

What Is GSTR-9C?

GSTR-9C is a reconciliation statement that is relevant to taxpayers whose aggregate turnover exceeds the prescribed threshold.

For eligible taxpayers exceeding ₹5 crore aggregate turnover, Rule 80(3) of the CGST Rules provides for furnishing GSTR-9C along with the annual return. GSTR-9C is currently a self-certified reconciliation statement, rather than a mandatory CA-certified statement.

Its purpose is essentially to reconcile figures reported in the annual GST return with the corresponding figures in the taxpayer's financial statements.

Why Reconciliation Matters Before Filing

One of the biggest practical challenges in annual GST compliance is that the numbers in GST returns do not always match the accounting records exactly.

Differences can arise because of:

• Credit notes or debit notes issued at different times
• Amendments to invoices
• Transactions reported in a subsequent financial year
• ITC reversals
• Exempt or non-GST supplies
• Advances and their subsequent adjustments
• Differences in accounting treatment
• Timing differences between books and GST returns

For example, suppose a company's books show taxable turnover of ₹10 crore, while the corresponding GST returns reflect ₹9.80 crore. The difference should not simply be adjusted to make the figures match. The business should identify what caused the ₹20 lakh difference and determine the appropriate treatment.

This reconciliation exercise is where GST Return Filing records, accounting data and supporting documents need to be considered together.

Documents and Records Required

Before starting the annual return, businesses should keep relevant records readily available, including:

• Filed GSTR-1 and GSTR-3B returns
• GSTR-2B and ITC records
• Sales and purchase registers
• General ledger and trial balance
• Audited or final financial statements, where applicable
• Details of credit notes and debit notes
• Details of amendments
• Export and import documentation, where relevant
• Records of ITC reversals and reclaims
• Details of tax payments and adjustments

Maintaining a reconciliation working paper can also make the review process easier and provide a clear explanation for material differences.

How to File GSTR-9

The practical filing process generally involves the following steps:

1. Complete the applicable periodic GST returns for the relevant financial year.
2. Download the relevant system-generated information available on the GST Portal.
3. Reconcile GST data with the books of accounts.
4. Review turnover and tax differences and identify their reasons.
5. Reconcile input tax credit, including reversals and other adjustments.
6. Complete the applicable GSTR-9 tables.
7. Review the return carefully before submission.
8. Pay any applicable additional liability through the prescribed mechanism.
9. File the return electronically using the applicable authentication method.

GSTN provides facilities to download relevant information and preview the annual return before filing. Once GSTR-9 is filed, it cannot be edited, making the pre-filing review particularly important.

GST Annual Return and GST Audit: Are They the Same?

No. A GST Annual Return and a GST Audit should not be treated as interchangeable terms.

GSTR-9 is an annual GST return. GSTR-9C is a reconciliation statement applicable to eligible taxpayers crossing the prescribed turnover threshold.

A separate audit may also be required under other applicable laws, such as company law or income-tax provisions, depending on the taxpayer's circumstances.

Therefore, completing GSTR-9 does not automatically mean that every accounting, tax or audit obligation has been completed.

Common Mistakes Businesses Should Avoid

A careful review can prevent several avoidable problems. Common issues include:

• Filing directly from portal-populated figures without reconciliation
• Ignoring differences between books and GST returns
• Incorrect reporting of ITC reversals
• Missing amendments made during the year
• Overlooking credit and debit notes
• Confusing GSTR-9 applicability with GSTR-9C applicability
• Failing to consider transactions reported in the subsequent financial year
• Submitting the return without reviewing the final draft

The objective should not be to make every figure artificially identical. The objective is to ensure that genuine differences are identified, understood and reported appropriately.

GST Annual Return Filing Checklist

Before filing, businesses can use this simple checklist:

• Confirm whether GSTR-9 is applicable.
• Check whether GSTR-9C is applicable.
• Reconcile turnover with the books.
• Reconcile output tax with GSTR-3B.
• Review ITC against relevant records, including GSTR-2B.
• Check credit notes, debit notes and amendments.
• Review exempt, zero-rated and non-GST supplies where applicable.
• Identify transactions reported after year-end.
• Investigate material differences.
• Review the completed return before filing.

Frequently Asked Questions

Is GSTR-9 mandatory for every GST-registered business?

No. For FY 2024-25 onwards, registered persons with aggregate turnover up to ₹2 crore are exempt from filing GSTR-9, subject to the applicable notification and taxpayer-specific provisions.

What is the due date for GSTR-9?

The statutory due date under Section 44 of the CGST Act is generally 31 December following the end of the relevant financial year, unless the Government extends or otherwise modifies the deadline.

For FY 2025-26, the ordinary statutory due date would therefore be 31 December 2026, subject to any subsequent Government notification.

Is GSTR-9C mandatory for businesses with turnover above ₹5 crore?

Eligible taxpayers exceeding ₹5 crore aggregate turnover are generally required to furnish GSTR-9C along with the annual return, subject to applicable exclusions and rules.

Can GSTR-9 be revised after filing?

No. GSTN's filing guidance states that GSTR-9 cannot be revised after it has been filed. Businesses should therefore complete their reconciliation and review before submission.

Does GSTR-9 replace monthly or quarterly GST returns?

No. The annual return does not replace periodic GST return filing. Applicable monthly or quarterly returns must continue to be filed according to the taxpayer's GST compliance requirements.

Why should businesses reconcile GST returns with their books?

Reconciliation helps identify reporting differences, ITC discrepancies, missed transactions, amendments and other issues before the annual return is finalised. It also provides a more reliable basis for preparing the annual return and, where applicable, GSTR-9C.

Conclusion

GST annual compliance is more than simply transferring figures from the GST Portal into GSTR-9. The quality of the filing depends heavily on the underlying reconciliation between GST returns, ITC records, accounting records and financial statements.

Businesses should first establish whether GSTR-9 and GSTR-9C apply to them, then reconcile the relevant figures and investigate significant differences before filing. This approach can make GST Return Filing more accurate and reduce the risk of avoidable compliance issues.
