GST Registration, Returns, Refunds and Notices
GST registration, returns, refunds, LUT for exports, and compliance
Our expert team registers MSMEs under GST, files the monthly or quarterly returns, reconciles input tax credit, prepares refund claims and the Letter of Undertaking for exports, and drafts replies to GST notices. GST returns are part of the Monthly Retainer (₹8,000 a month + GST); registration and refunds are quoted on their own, and a reply to a GST notice starts from ₹2,500 + GST.
Who it is for
- A new business that has crossed the registration limit, or needs a GSTIN to sell to registered buyers or on marketplaces
- MSMEs filing GSTR-1 and GSTR-3B every month or under the quarterly (QRMP) scheme
- Exporters and suppliers to SEZs who supply without paying IGST, or who are owed a refund
- Businesses whose input tax credit does not match GSTR-2B
- Anyone who has received a GST notice or an intimation
What our expert team does
Registration
We check whether registration is needed and under which scheme (regular or composition), prepare the application with your documents and file it on the GST portal, and answer the officer’s queries until it is decided.
Return filing
Each period we collect your sales and purchase data, prepare GSTR-1 and GSTR-3B (or the composition returns), and file them after you approve the figures and the tax payable.
Credit reconciliation
We match the input tax credit in your books with GSTR-2B every period and tell you which suppliers have not uploaded invoices, before a mismatch turns into a notice.
Annual return
Where it applies, we prepare the annual return from the year’s filed returns and your books.
LUT and refunds
For exports and SEZ supplies we file the Letter of Undertaking for each financial year, and prepare and file refund claims with the statements and documents the portal asks for.
Notices
If a notice arrives, we read it with you, collect the records it asks for, draft the reply and file it before the due date. Hearings that need an authorised representative are attended by qualified professionals of our associated firm.
What you receive
- The GST registration certificate, once the department approves it
- Filed returns with their acknowledgements and the tax payable each period

Frequently asked questions
When does an MSME need GST registration?
When its turnover crosses the limit set for its kind of supply and State, and in some cases regardless of turnover, for example for inter-State supplies of goods or selling through an e-commerce operator. Our guide to GST registration for MSMEs sets out the limits and the exceptions. Some units register voluntarily because their buyers want tax invoices or a scheme asks for a GSTIN.
Monthly returns or the quarterly QRMP scheme — which suits me?
Small taxpayers below the QRMP limit can file GSTR-1 and GSTR-3B quarterly while paying tax monthly. Whether it suits you depends on your buyers, who may want your invoices in GSTR-1 every month. Our guide to GST return due dates compares the two.
Why does my input tax credit not match GSTR-2B?
Usually because a supplier filed late, filed under the wrong GSTIN or has not filed at all. We list the gaps every period so you can follow up with the supplier before claiming. Our guide to the input tax credit rules explains the conditions.
Do exporters need an LUT?
An exporter, or a supplier to an SEZ, who wants to supply without paying IGST and claim a refund of unused input tax credit instead, files a Letter of Undertaking on the GST portal for each financial year. We check whether it suits your exports and file it.
Can you reply to a GST notice?
Yes. We draft the reply and file it with the records it needs; the published fees are on the tax notices page. Our free notice decoder tells you what a notice is and how long you have, before you call us.
