Introduction

A tax audit under Section 44AB of the Income-tax Act, 1961 is a mandatory compliance requirement for specified businesses and professionals whose turnover or gross receipts exceed the prescribed limits.

The primary objectives are:

• Ensure proper maintenance of books of account.

• Verify the correctness of income declared.

whichever is lower, unless the taxpayer establishes a reasonable cause for the failure.

Practical Example

Example 1

ABC Traders has:

• Turnover: ₹8 crore

• Cash Receipts: 2%

• Cash Payments: 3%

Since both cash receipts and cash payments are within 5%, the enhanced threshold of ₹10 crore applies.

Result: Tax audit is not required.

Example 2

XYZ Traders has:

• Turnover: ₹2 crore

• Cash Receipts: 20%

As the cash receipt condition is not satisfied, the standard ₹1 crore limit applies.

Result: Tax audit is required.

Common Mistakes to Avoid

• Ignoring cash transaction limits.

• Incorrect turnover calculation.

• Missing the audit due date.

• Delaying the appointment of the auditor.

• Incomplete books of account.

• Incorrect reporting in Form 3CD.
