5. High-Frequency Exam Traps

Trap 1: Cash limit for 5% includes non-turnover receipts!
For the ₹ 10 Crore turnover limit, the 5% cash restriction applies to ALL RECEIPTS (including loans, capital contributions, sale of assets), NOT just turnover!
Trap 2: Tax audit due date vs return filing due date!
The tax audit report must be submitted by 30th September, while the return of income is filed by 31st October. Filing the audit report after 30th September attracts Section 271B penalty even if return is filed before 31st October!
