GST audit is one of those compliance topics that many businesses only notice when filing deadlines approach. In reality, the question is not only whether an audit applies, but also whether your turnover, return history, and annual filing position place you in the relevant compliance bracket.
For FY 2025–26, the term “GST audit” is often used loosely to describe annual return and reconciliation obligations, because the compulsory CA/CMA audit under GST was removed and replaced with self-certified reconciliation in the annual filing framework. That means businesses should first understand what kind of audit or annual compliance is actually required, and then test where they fall based on turnover.
This article explains the GST audit thresholds in a practical way so businesses can check their position early. It is shared for knowledge and informational purposes for readers of Taxation Legal Advisor.
What GST audit means today
The GST compliance system has changed over time. Earlier, certain taxpayers had to undergo GST audit by a Chartered Accountant or Cost Accountant, but that mandatory professional certification was removed from the statute in 2021.
Today, the compliance focus is on annual return filing and self-reconciliation. In practice, many people still call this a GST audit, but the main filings now are GSTR-9 and, where applicable, GSTR-9C in a self-certified format.
So, when you ask whether you fall under the GST audit bracket in FY 2025–26, you really need to check two things: whether annual return filing applies to you, and whether the reconciliation statement also applies based on turnover.
The key turnover test
GST audit-related annual filing is generally determined on the basis of aggregate turnover, not merely the turnover of a single GST registration. Aggregate turnover includes taxable, exempt, and export supplies on an all-India PAN basis, which means all GST registrations under the same PAN need to be considered together.
That PAN-level view is important because a business may think each branch is below the threshold, while the combined turnover crosses the applicable limit. In that case, annual compliance obligations may still apply.
This is why businesses should not check only one GSTIN in isolation. The correct question is whether the total turnover across all GST registrations under one PAN crosses the relevant limit for annual filing and reconciliation.
Thresholds to watch
For FY 2025–26, the commonly cited GST annual return thresholds are as follows: businesses above ₹2 crore aggregate turnover generally need to file GSTR-9, and businesses above ₹5 crore aggregate turnover generally need to file both GSTR-9 and GSTR-9C in self-certified form.
This means the bracket is not a single line. A business between ₹2 crore and ₹5 crore may need the annual return but not the reconciliation statement, while a business above ₹5 crore may need both.
Public references also indicate that businesses below ₹2 crore are generally outside the annual return requirement, although they should still maintain proper records and monthly GST discipline.
If your turnover is below ₹2 crore
If your aggregate turnover is below ₹2 crore, you are generally outside the compulsory GSTR-9 filing bracket for this purpose. That does not mean compliance is low-effort; it only means the annual return requirement may not apply in the same way as it does for larger taxpayers.
Even if the annual return is not mandatory, regular return filing, ITC reconciliation, and proper invoice documentation remain essential. A small business can still face notices or mismatches if its monthly filings do not align with books and supplier records.
So, being below the threshold is not the same as being outside GST scrutiny. It only means the annual filing burden is lighter.
If your turnover is between ₹2 crore and ₹5 crore
Businesses in this range should pay close attention because they are usually in the GSTR-9 bracket. In practical terms, this is the zone where annual return reconciliation becomes important even if the business does not need the reconciliation statement.
This bracket often includes growing traders, manufacturers, service firms, and multi-branch businesses that are large enough to have meaningful GST exposure but not always large enough to have a complex finance team.
For such businesses, the main risk is not just filing the annual return late. The bigger risk is filing an annual return that does not match the monthly returns, because that creates reconciliation issues later.
If your turnover is above ₹5 crore
If aggregate turnover crosses ₹5 crore, the self-certified reconciliation statement becomes relevant along with the annual return. That means your GST reporting needs to be more disciplined because the annual numbers must be capable of being matched against the books and monthly returns.
This is the bracket where businesses should be especially careful with ITC, exempt supplies, RCM, output tax, and stock movement records. Any unexplained difference can become visible in the reconciliation statement and may need explanation later.
Even though the certification is self-certified now, the responsibility remains significant. Self-certification does not reduce accountability; it only changes who signs the reconciliation statement.
Why turnover is not the only factor
Turnover is the main threshold test, but it is not the only thing that matters. A business with lower turnover can still face GST scrutiny if its returns contain major mismatches or if its credit and sales records are not properly maintained.
Conversely, a larger business may stay compliant if its systems are disciplined and its reconciliations are timely. In that sense, threshold applicability is only the starting point; filing quality matters just as much.
This is why businesses should not wait until the year-end to think about audit exposure. The filing trail created during the year will shape how easy or difficult the annual compliance process becomes.
How to check your position
To see whether you fall under the audit bracket, start with an all-India turnover computation for the year. Include taxable supplies, exempt supplies, and exports under the same PAN.
Then compare that figure with the applicable thresholds. If you are below ₹2 crore, your annual return obligation may be lower. If you are between ₹2 crore and ₹5 crore, GSTR-9 is likely relevant. If you are above ₹5 crore, you should also plan for the reconciliation statement.
After that, review the quality of your monthly filings. If your GSTR-1, GSTR-3B, GSTR-2B, and books do not align, the annual filing will be harder regardless of threshold.
Practical records to review
Before deciding whether you fall in the audit bracket, businesses should review sales registers, purchase registers, ITC workings, tax payments, credit notes, debit notes, exempt turnover, and stock reconciliation.
They should also ensure that branches and GST registrations under the same PAN are consolidated correctly for turnover testing. A branch-wise view can be useful internally, but the threshold test itself should be done on the aggregate PAN basis.
The more organized the records, the easier it is to confirm whether the annual filing and reconciliation requirements apply.
Common mistakes businesses make
A common mistake is checking only one GST registration and ignoring other registrations under the same PAN. That can lead to underestimating turnover and missing annual filing obligations.
Another mistake is confusing annual return filing with departmental audit. Annual filing is a return obligation; departmental audit, where initiated, is a separate process based on risk or scrutiny parameters.
A third mistake is assuming that self-certified GSTR-9C means the exercise is simple. In fact, self-certification still requires a proper reconciliation between books and GST returns.
Final note
For FY 2025–26, the GST audit question is really a turnover and filing question. If your aggregate turnover is below ₹2 crore, your annual filing burden is usually lighter. Between ₹2 crore and ₹5 crore, annual return filing becomes more relevant. Above ₹5 crore, reconciliation reporting also comes into the picture.
The safest approach is to check your PAN-level turnover early, reconcile monthly, and keep your GST data aligned through the year. That makes annual filing easier and reduces the chance of surprises later.
