GST Registration and Tax liability Date

Yes you are liable to pay GST for Feb & March also.

As per Rule 53(2) of CGST Act : You need to issue revised tax invoice in respect of all taxable supplies effected during the period starting from the effective date of registration till date of of issuance of certificate of registration.
provided that you may issue the consolidated revised tax invoice in respect of all B2C taxable supplies.

So need to consider all supplies made from the effective date of registration till date of issuance of certificate

Ist lacunae
gst liability arises from the date of registration. Any liability incurred before that date will be included after issuing tax invoice from that date .
But date of registration and liability cannot be a different date.

YES THE DATE OF LIABILITY & REGISTRATION DATE CAN BE DIFFERENT BECAUSE AS PER SECTION 25 THE PERSON WHO IS LIABLE FOR REGISTRATION CAN GRANT REGISTRATION WITHIN 30 DAYS.

U may have accept debit note from supplier on the grounds of ur invoices,then u may issue credit note to ur suppliers with effect from 01/07/2022 or with in the 180 days.Ur Feb return or sept 2023 return or ur anual return used for the clarification any issues for claiming ITC .which enable to claim ITC of ur closing before registration date 24/02/2023.

GST liability starts from the date you CROSS the threshold, not from the date your GSTIN is allotted.

Here is what that means practically:
- If you crossed Rs 20 lakh (services) or Rs 40 lakh (goods) in May, your obligation to collect GST on supplies begins from that May date, even before you registered.
- After getting your GSTIN, you declare the supplies made in that gap period in your first GSTR-1 return.
- If you collected GST from customers but did not deposit it: pay it now with interest at 18% per annum from the due date.
- If you did NOT collect GST during the gap: technically you are liable for the tax, payable from your own pocket, since you were required to register earlier.

Exception: If you applied for voluntary registration (before crossing the threshold), liability starts from your registration effective date, not retrospectively.
