Why it matters for tax: section 43B(h)

If you buy from a registered micro or small enterprise, you must pay within 15 days, or within the agreed period up to 45 days. Otherwise, the expense is allowed for income tax only in the year you actually pay. Suppliers with Udyam registration get paid faster; buyers who are late pay more tax.

Other benefits

  • Collateral-free loans and priority-sector lending
  • Protection under the MSMED Act against delayed payments
  • Concessions in government tenders and some state schemes

Common mistakes

  • Paying for a 'Udyam certificate' through a lookalike paid website; the official portal is free
  • Buyers ignoring the 45-day rule and losing the expense deduction
