Under section 44AE, presumptive income from a HEAVY goods vehicle (gross vehicle weight exceeding 12,000 kg) is computed at:

1. For heavy goods vehicles (gross vehicle weight exceeding 12,000 kilograms), section 44AE deems income at Rs 1,000 per ton of gross vehicle weight (or unladen weight) per month or part of a month. 2. The month count runs on OWNERSHIP, not on actual plying — a vehicle bought in April but used from July still counts from April. 3. Rs 7,500 per month (or part) applies to goods carriages other than heavy vehicles. 4. Option B is the trap: substituting months of use for months of ownership understates the presumptive income. _Source: ICAI CA Inter P3(A) Income-tax SM (May 2026), Ch 3 Unit 3 PGBP, PDF p. 121_
