Tax Audit Limit for Business: ₹1 Crore vs ₹10 Crore

CA Nikhil Gupta·Aug 2026·7 min readIncome Tax

The ordinary business tax-audit threshold is ₹1 crore.

For broader context, see the Income Tax and Salary Hub.

It increases to ₹10 crore only when cash receipts and cash payments each do not exceed 5% of their respective totals.

Legal or Computational Framework

Governing rule

Tax Year 2026–27 uses section 63 of the Income-tax Act, 2025. Presumptive opt-out, special businesses and entity facts can create audit even below the headline threshold.

Use the Tax Audit Applicability Checker — Section 44AB / Section 63 to apply these points to your figures or facts.

Correct calculation method

Determine turnover; calculate cash-receipt percentage; calculate cash-payment percentage; test presumptive history; check audit report due date and filing.

Step-by-step workflow

Determine turnover.
calculate cash-receipt percentage.
calculate cash-payment percentage.
test presumptive history.
check audit report due date and filing.

Worked example

Turnover ₹8 crore with 3% cash receipts but 7% cash payments does not qualify for the ₹10 crore relaxation.

The example is an illustration, not a substitute for the taxpayer's facts. A change in status, period, payment mode, document, city, asset, relationship or scheme can change the result.

Why generic pages get this wrong

Search pages often state a rate or limit without identifying the governing base. The calculation must distinguish gross receipt from taxable profit, tax from TDS, a deduction from an exemption, salary from business income, and an accounting entry from the tax treatment.

Decision matrix

Decision point	Required treatment
Legal year	Use the Act, rules and notification effective for the income or transaction period
Taxpayer category	Confirm residence, age, entity, employee/business status and regime
Calculation base	Use the statutory definition rather than CTC, net bank receipt or accounting label
Ceiling or rate	Apply actual-amount, percentage, shared, lifetime and gross-income limits in sequence
Documentation	Link every input to an invoice, statement, contract, certificate or official record
Final output	Show tax, surcharge, cess, interest and TDS/TCS credits separately

Finin2min Summary

In short: ₹1 crore is the default trigger for a business tax audit. That threshold only moves to ₹10 crore where both cash receipts and cash payments stay within 5% of turnover — miss either 5% test and the ₹1 crore limit applies regardless of overall turnover.

Finin2min rule: establish eligibility, calculate transparently, and preserve an audit trail.

Frequently Asked Questions

What is the direct answer for “tax audit limit business 10 crore”? ▼

The ordinary business tax-audit threshold is ₹1 crore. It increases to ₹10 crore only when cash receipts and cash payments each do not exceed 5% of their respective totals.

Which law and tax period apply? ▼

The governing provision for Tax Year 2026–27 is Section 63 of the Income-tax Act, 2025 (the successor to Section 44AB). AY 2026-27 return filings still reference the 1961 Act’s numbering. Even a turnover comfortably under ₹1 crore does not guarantee no audit — opting out of the presumptive scheme after using it, or falling into certain specified businesses, can trigger audit regardless of the headline threshold.

How should the amount be calculated? ▼

Work through it in order: pin down total turnover for the year, work out cash receipts as a percentage of total receipts, work out cash payments as a percentage of total payments, check whether presumptive taxation was used or opted out of in a prior year, and confirm the audit report’s due date once you know whether an audit applies.

What does the worked example show? ▼

No — in the article’s own example, a business with ₹8 crore turnover clears the 3% cash-receipts test but fails on cash payments at 7%, above the 5% ceiling. Because both tests must pass, not just one, this business stays on the ₹1 crore threshold and needs an audit despite its receipts-side percentage looking fine.

Which documents should be kept? ▼

Keep turnover reconciliation, cash receipt/payment matrix, books and trial balance, presumptive history. The calculation should be reproducible from these records.

What is the most common mistake? ▼

Two errors show up most often: checking only the cash-receipts percentage and ignoring cash payments, when both must independently pass the 5% test; and running the calculation on profit or net income instead of gross turnover, which understates the figure the threshold actually applies to.
