Tax compliance is an important responsibility for every business and professional in India. One of the key compliance requirements for eligible taxpayers is a tax audit under Section 44AB of the Income Tax Act, 1961. A tax audit helps verify whether books of accounts have been properly maintained and whether income, expenses, deductions and other tax particulars have been correctly reported.
For FY- 2025-26 (AY-2026-27), the existing Section 44AB framework under the Income Tax Act, 1961 continues to apply. The Income Tax Department has clarified that the tax audit report for this year is required to be filed using Form 3CA/3CB along with Form 3CD. The general due date for furnishing the tax audit report is 30 September 2026. In transfer-pricing cases where the income-tax return is due on 30 November 2026, the tax audit report is generally due on 31 October 2026.
What Is Tax Audit Under Section 44AB?
A tax audit is an examination of the books of accounts and financial records of a taxpayer by a qualified Chartered Accountant. The objective is to ensure that the taxpayer has complied with applicable provisions of the Income Tax law and that the information reported to the Income Tax Department is accurate.
Tax audit requirements are primarily linked to the taxpayer's business turnover, gross receipts from profession and certain situations involving presumptive taxation.
It is important to understand that crossing the turnover threshold is not the only factor that can make a tax audit applicable. Certain taxpayers may also become liable for audit when they declare income below the prescribed presumptive taxation limits or do not satisfy the conditions of the relevant presumptive taxation provisions.
Latest Section 44AB Turnover Limits
For businesses, the standard tax audit threshold is ₹1 crore in total sales, turnover or gross receipts.
However, there is an important relaxation for businesses having a high proportion of digital or non-cash transactions. The threshold can effectively increase to ₹10 crore, provided:
- Cash receipts do not exceed 5% of total receipts; and
- Cash payments do not exceed 5% of total payments.
The Income Tax Department's current guidance confirms these thresholds and the 5% cash-transaction conditions.
For example, if a business has an annual turnover of ₹7 crore but keeps both its cash receipts and cash payments within the prescribed 5% limits, it would generally not be subject to tax audit merely on account of turnover, provided the prescribed conditions are satisfied and no other provision independently requires an audit.
Businesses should therefore monitor not only turnover but also their cash transactions throughout the financial year.
Tax Audit Limit for Professionals
Professionals are subject to a separate threshold. Generally, a tax audit becomes applicable when gross professional receipts exceed ₹50 lakh during the financial year.
This can be relevant for lawyers, doctors, architects, accountants, consultants and other specified professionals covered by the applicable provisions.
There are also situations where the threshold can be affected by presumptive taxation provisions. For instance, the Income Tax Department's current forms and validation rules recognise specific conditions relating to Sections 44AD and 44ADA.
Therefore, professionals should not determine audit applicability solely by looking at their gross receipts. The method of taxation and the income declared also need to be examined.
When Is Tax Audit Required Under Presumptive Taxation?
Presumptive taxation can simplify tax compliance for eligible businesses and professionals. However, a taxpayer who is subject to presumptive taxation provisions and declares income below the prescribed level, or opts out of the presumptive taxation scheme in circumstances covered by the law, may become liable to tax audit.
For example, taxpayers covered by provisions such as Sections 44AD, 44ADA and 44AE need to carefully evaluate whether their declared income and other conditions comply with the applicable rules.
The audit consequences depend on the specific presumptive-taxation provision, the income declared and the conditions applicable to the taxpayer.
This makes professional tax advice particularly useful when a taxpayer is considering whether to adopt or discontinue presumptive taxation.
Tax Audit Due Date for FY 2025-26
For FY 2025-26 / AY 2026-27, the tax audit report is generally required to be furnished by 30 September 2026.
However, in transfer- pricing cases covered by Section 92E, where the income-tax return filling due date is 30 November 2026, the tax audit report is generally required to be furnished by 31st October 2026.
The fact that the audit report may be filed after 1st April 2026 does not shift FY 2025-26 audits to the new Income Tax Act, 2025. FY 2025-26/ AY 2026-27 continues to be governed by the Income Tax Act, 1961, and the prescribed audit forms under the old Act continue to apply.
Taxpayers should not wait until the last few days to begin the audit process. The Chartered Accountant may require invoices, bank statements, ledgers, GST records, expense documents, fixed-asset details and other supporting information before finalising the report.
Which Forms Are Used for Tax Audit?
For FY 2025-26 (AY 2026-27), the Income Tax Act, 1961and the existing tax-audit forms continue to apply.
Depending on the circumstances, the tax audit is reported through:
- Form 3CA, where the taxpayer's accounts are already required to be audited under another law;
- Form 3CB, in other applicable cases; and
- Form 3CD, which contains the statement of particulars required under the tax-audit provisions.
The Income Tax Department has specifically clarified that FY 2025-26 tax audits must be filed using Form 3CA/3CB, as applicable, along with Form 3CD, even where the report is actually furnished after April 2026.
Penalty for Failure to Get Tax Audit Done
Failure to comply with the tax-audit requirement can result in a penalty under Section 271B of the Income Tax Act, 1961.
The penalty may be 0.5% of the total sales, turnover or gross receipts, subject to a maximum of ₹1.50 lakh.
Section 271B covers failure to get the accounts audited as required as well as failure to furnish the audit report within the prescribed time.
Section 271B covers failure to get the accounts audited as required as well as failure to furnish the audit report within the prescribed time.
However, penalty provisions should not be viewed in isolation. Where a taxpayer can demonstrate a reasonable cause for the failure, the applicable penalty may be considered for relief under the relevant provisions.
Section 273B provides relief from certain penalties, including penalty under Section 271B, where the taxpayer proves that there was reasonable cause for the failure.
Taxpayers should therefore maintain proper documentation if circumstances beyond their reasonable control contributed to a delay or failure in compliance.
How Can Businesses Avoid Tax Audit Compliance Issues?
Businesses and professionals can reduce compliance risks by taking a proactive approach. Some practical steps include:
- Monitor turnover regularly: Do not wait until year-end to determine whether the audit threshold has been crossed.
- Track cash transactions: Maintain proper records of cash receipts and payments, particularly where the ₹10 crore threshold may be relevant.
- Reconcile GST and accounting records: Differences between GST returns, books and income-tax reporting can create unnecessary compliance concerns.
- Maintain supporting documents: Preserve invoices, bank statements, expense records and other relevant documents.
- Start the audit process early: Give your Chartered Accountant sufficient time to review the books and identify discrepancies.
- Review presumptive-taxation eligibility: If you are using or discontinuing a presumptive taxation scheme, assess the audit implications in advance.
- Review transfer-pricing applicability : Where international or specified evaluate whether Section 92E applies, as this can affect the applicable return and tax- audit-report due dates.
