Receivo is a tool, not a law firm, and this is not legal advice.

Due dates follow MSMED Act Section 15; interest follows Section 16.

What the law says about late payment

Three provisions decide when you must be paid and what a late buyer owes. Here they are in plain words; the rules page quotes each Act in full.

Section 15

MSMED Act, 2006 · Liability of buyer to make payment

Your buyer must pay by the date agreed in writing. With nothing in writing, they must pay within 15 days of accepting the goods or services. No written term can stretch past 45 days.

Section 16

MSMED Act, 2006 · Date from which and rate at which interest is payable

Pay late and the buyer owes compound interest, added every month, at three times the RBI Bank Rate. It starts the day after the due date, and no contract can waive it.

Section 43B(h)

Income-tax Act, 1961 · Certain deductions to be only on actual payment

Inserted by the Finance Act 2023 from FY 2023–24: a buyer who pays a micro or small supplier after the Section 15 limit can claim that expense only in the year they actually pay.

Read the full rules, with examples →

Section 16 rate used by Receivo: 3 × the RBI Bank Rate of 5.50% (effective 5 December 2025) = 16.50% a year, compounded monthly. Still unpaid? Section 18 lets you refer the dispute to your state's MSE Facilitation Council via the MSME Samadhaan portal.
