Section 58 · was Section 44AD / 44ADA in the 1961 Act
Small businesses (turnover ≤ ₹3 crore) and professionals (receipts ≤ ₹75 lakh) can declare income at a deemed rate without detailed books of accounts.
Who it applies to: Small traders, shopkeepers, and self-employed professionals (doctors, lawyers, engineers, consultants) with income below the turnover threshold.
Rekha is a freelance HR consultant with annual billings of ₹60L (all via bank transfers). She opts for presumptive taxation under Section 58 (professionals — 50% rate).
Gross receipts: ₹60,00,000 Presumed income: 50% × ₹60L = ₹30,00,000 Tax on ₹30L (default regime): ₹0–4L: Nil ₹4L–8L: 5% = ₹20,000 ₹8L–12L: 10% = ₹40,000 ₹12L–16L: 15% = ₹60,000 ₹16L–20L: 20% = ₹80,000 ₹20L–24L: 25% = ₹1,00,000 ₹24L–30L: 30% = ₹1,80,000 Total: ₹4,80,000 Plus 4% cess: ₹4,99,200
Result: Rekha pays tax on ₹30L deemed income without proving her actual expenses. If her real expenses are less than 50% of billings (e.g., she works from home with minimal overhead), presumptive taxation is disadvantageous. If expenses exceed 50%, she should consider detailed accounting instead.
Vinod runs a hardware store with ₹1.5 crore annual turnover — 80% via UPI/card (digital), 20% cash. He opts for presumptive taxation.
Digital receipts (80%): ₹1,20,00,000 → presumed income @ 6% = ₹7,20,000 Cash receipts (20%): ₹30,00,000 → presumed income @ 8% = ₹2,40,000 Total presumed income: ₹9,60,000 Tax on ₹9,60,000 (default regime): ₹0–4L: Nil ₹4L–8L: 5% × ₹4L = ₹20,000 ₹8L–9.6L: 10% × ₹1.6L = ₹16,000 Total: ₹36,000 + 4% cess = ₹37,440
Result: Vinod pays ₹37,440 tax on ₹1.5 crore turnover — without audited accounts or detailed books. Encouraging customers to pay digitally lowers his presumed income rate from 8% to 6%, saving him tax.
