What GST Desk does and doesn't do
- Kubertree prepares returns. Filing and tax decisions stay with your business and your CA.
- Nothing is filed until your accountant or CA has approved the return.
- Mismatches with GSTR-2B are shown to you, never quietly adjusted.
- Due dates follow the notified schedule. When a date is extended, the calendar is updated.
Questions
Asked about GST Desk
01Does Kubertree file the return for me?
No. It prepares GSTR-1 and GSTR-3B and the JSON for the portal. You or your CA review and file.
02What happens to ITC from suppliers who have not filed?
It is shown as at risk, not claimable, with the supplier and amount. When they file and it appears in 2B, it moves to claimable.
03We file quarterly under QRMP. Does that work?
Yes. IFF, PMT-06 and the quarterly GSTR-3B are supported, with the dates for your state.
