We owe money to MSME suppliers — what's this half-yearly return?
The short answer
If your company owes micro or small suppliers beyond 45 days of acceptance, you must file MSME-1 with the ROC for each half-year. The return for April–September is due by 31 October; the October–March period is due by 30 April. Section 405 of the Companies Act and Section 15 of the MSMED Act drive this — and the parallel income-tax bite under Section 43B(h) can disallow those dues in your return.
The sequence
- 1Identify dues to micro and small suppliers still outstanding beyond 45 days of acceptance
- 2Compile supplier details and outstanding amounts for the relevant half-year window
- 3File MSME-1 on the MCA portal before the statutory deadline for that period
- 4Reconcile the filing with your books and flag any amounts at risk under Section 43B(h)
