Who needs GST registration
Registration is compulsory once turnover crosses ₹40 lakh a year for goods or ₹20 lakh for services in most states, including Tamil Nadu and Maharashtra.
Some businesses must register from the first sale whatever the turnover, for example anyone selling goods to buyers in other states.
Once registered, monthly filers pay the tax and file GSTR-3B by the 20th of the following month.

GST questions
How long does GST registration take?
It depends on the officer’s review and on verification. You get the status at each step, and we answer any query the officer raises.
Can I register a business I run from home?
Yes. Your electricity bill or property tax receipt works as the address proof.
I had no sales this month. Do I still file?
Yes. A nil GSTR-3B is still due by the 20th, and a late nil return attracts a late fee of ₹20 a day.
Can you file my pending returns?
Yes. Share the portal access and the bills for the pending months. We file them in order and tell you the late fee and interest before work starts.
Do you handle the composition scheme?
Yes. Composition taxpayers file a quarterly statement and an annual return, and we track both dates.
What does the fee include?
Preparation and filing. Tax, interest and late fees paid to the government are separate.
