Section 343 - Deductions in respect of certain payments / income - Section 343

Deductions in respect of certain payments / income - Section 343. Section 343 of the Income Tax Act 2025 sits in Chapter XVII (Deductions in respect of certain payments / income). In force from 1 April 2026.

Key provisions

• *Resident individuals and Hindu Undivided Families (HUFs)** who have opted out of the new tax regime under Section 202. NRIs and foreign companies are generally not entitled to Chapter XVII deductions.
• A client opts into the **old tax regime** under Section 202(2), which is now an opt-in (not the default).
• Evidence of qualifying investment or payment is on file and dated within the tax year.
• The combined cap across Sections 321-323 (₹1,50,000) is not exceeded.
• The taxpayer's marginal rate makes the deduction worth more than the new regime's lower slab rate. ThynkTax's regime-comparison calculator runs this automatically - most salaried taxpayers earning above ₹12 lakh with rent, home loan interest, and ₹1.5 lakh of 80C-eligible investments find the old regime more favourable.
• **Section 342** - immediately preceding provision in the same chapter.
• **Section 344** - immediately following provision in the same chapter.
• The full chapter spans Sections 321 to 350.
