GST return filing for a Mumbai business — what to get right
Returns go to the one national GST portal, but a Mumbai business is administered by the CGST Mumbai Zone (Centre) or the Maharashtra GST Department (State, mahagst.gov.in) — and Maharashtra has its own quirks on due dates and Professional Tax. Three things keep a Mumbai file clean:
1 · Your Maharashtra due dates
Monthly: GSTR-1 by the 11th, GSTR-3B by the 20th. QRMP (quarterly, turnover ≤ Rs 5 cr): Maharashtra files GSTR-3B by the 22nd (the 22nd group — Delhi is 24th), quarterly GSTR-1 by the 13th, monthly tax via PMT-06 by the 25th. We pick the cycle that costs you least work and file to the exact date.
2 · ITC you'd otherwise lose
Every month we match your purchase register to GSTR-2B and flag suppliers who haven't filed — so you claim only credit that's actually there and chase the rest before the annual 30 November cut-off. In a city of sub-contracted vendors, this is where margins quietly leak. Included in the Rs 449 fee.
3 · Professional Tax rides along
If you have staff in Mumbai, Maharashtra's PTRC return (and PTEC) run alongside GST under the 1975 Act — a separate portal, separate dates, commonly forgotten until a notice. We file PTRC in the same monthly cycle as your GST returns.

GST Return Filing in Mumbai — FAQs
What are the GST return due dates for a Mumbai business?
Monthly: GSTR-1 by the 11th, GSTR-3B by the 20th. Under QRMP (turnover up to Rs 5 crore), Maharashtra files GSTR-3B by the 22nd (the 22nd group, not the 24th), quarterly GSTR-1 by the 13th, and pays monthly via PMT-06 by the 25th. We track whichever cycle applies.
Monthly or QRMP — which should I pick?
Turnover up to Rs 5 crore can opt for QRMP and file GSTR-3B quarterly (Maharashtra: the 22nd), which cuts work while still paying monthly. Above Rs 5 crore, monthly is mandatory. If you sell B2B, the optional IFF keeps your buyers' credit flowing on the quarterly scheme.
Do you handle Professional Tax (PTRC) in Maharashtra too?
Yes. A Mumbai business with employees files the Maharashtra PTRC return and holds PTEC, under the 1975 Act — separate from GST. We file it in the same monthly cycle so nothing is missed.
What if I miss a Mumbai GST due date?
A late return carries interest under Section 50 and a late fee under Section 47, and your buyers can lose credit until you file. We remind before every due date and file on time; if you're behind, we clear the backlog first.
How does the GSTR-2B reconciliation save me money?
We match your purchase register to GSTR-2B every month and flag suppliers who haven't filed, so you claim only available credit and chase the rest before the 30 November cut-off. Included in the Rs 449 fee.
How much does it cost in Mumbai?
Rs 449 a month for regular filing (up to 100 invoices), government fee nil. For a running business with employees, the Growth plan at Rs 1,999 a month bundles returns, 2B reconciliation, bookkeeping and TDS.
