Tax Audit Applicability
Complete Guide
Sections 44AB · 44AD · 44ADA · 44AE | CA Devesh Thakur
If there is one chapter in Direct Tax that consistently confuses students, tax professionals, and business owners alike, it is Tax Audit Applicability under Section 44AB.
These doubts arise because Sections 44AB, 44AD, 44ADA, and 44AE are studied separately — but the Income-tax Act links them together. The easiest way is to think of it as a single decision tree.
Step 1: Identify the Category
Every tax audit case starts from one of these branches:
- Business under normal provisions
- Profession under normal provisions
- Presumptive Business under Section 44AD
- Presumptive Profession under Section 44ADA
- Goods Carriage Business under Section 44AE
A common mistake: jumping to turnover limits without identifying the applicable provision first.
Section 44AB: Tax Audit for Business
Basic Rule
A person carrying on business is required to get accounts audited if total sales, turnover, or gross receipts exceed ₹1 crore during the previous year.
Enhanced Limit of ₹10 Crore
The threshold increases to ₹10 crore if both conditions are satisfied:
- Cash receipts do not exceed 5% of total receipts
- Cash payments do not exceed 5% of total payments
Rahul Traders — Cash ≤ 5%
- Turnover: ₹8 crore
- Cash R: 2% | Cash P: 3%
- Limit = ₹10 Cr → No Audit ✓
Rahul Traders — Cash > 5%
- Turnover: ₹8 crore
- Cash P rises to 8%
- Limit drops to ₹1 Cr → Audit ✔
Section 44AB: Tax Audit for Profession
A professional must get accounts audited if gross receipts exceed ₹50 lakh. The ₹10 crore enhanced limit does not apply to professionals.
Presumptive taxation simplifies compliance for small taxpayers — declare a fixed % of turnover as income instead of maintaining detailed books.
