How to read the result
This calculator works for any two consecutive months, and festive months are its default example. The table shows the GST cash you would pay for each return after every credit you can use. If the total is above the cash you can set aside, the gap is the amount to plan for before the due date.
Returns hit festive sellers hard. Credit notes for returns reduce your output GST, but only in the return where you issue them, so a big return wave in November can leave October's cash payment higher than the final position.
What the estimate assumes
- You file GSTR-3B monthly, on the 20th. QRMP filers pay differently.
- Sales are GST-inclusive, taxed at 5% or 18% in the mix you choose.
- Purchases carry 18% GST and all of it appears in your GSTR-2B. Any ITC that does not match GSTR-2B will not be allowed, which raises your cash payment.
- Platform fees carry 18% GST that you claim as ITC.
- TCS of 0.5% on net taxable value is available as credit in your cash ledger.
