New TDS and TCS Return Forms in 2026: Form 138, 140, 144 and 143 Explained (Q2 Due 31 October)

The Income-tax Act, 2025 replaced the 1961 Act from 1 April 2026. If your business deducts TDS, the biggest visible change is the form numbers. The return for July–September 2026 is due on 31 October 2026, so this is a good time to check you are using the right ones.

Old form, new form

The 'assessment year' is gone too. Returns and certificates now refer to the tax year, which is the same as the financial year. TDS provisions sit in sections 392 to 394 of the new Act, so make sure your accounting software and returns use the updated payment codes.

TDS deducted in a month is normally deposited by the 7th of the next month (March deductions by 30 April). A late return costs ₹200 for every day of delay, and interest runs at 1% a month for late deduction and 1.5% a month for late deposit.

Common mistakes to avoid

  • Wrong or missing PAN of the payee, which means a higher TDS rate and no credit for them
  • Challan details that don't match the return
  • Filing salary TDS in the wrong form (Form 138 is for salaries only)
  • Issuing old-format certificates instead of Form 130 and Form 131
