The path of a GST dispute
From the first notice to the Tribunal, one team on your file
Most GST disputes can be closed early with a well-documented reply. When they cannot, the same team that wrote your reply takes the case to appeal, so nothing is lost between stages.
Time limits & pre-depositsNotice or intimation
We reconcile your data and reply so the matter closes at this stage where possible.
Show cause notice & adjudication
Point-wise reply, documents, case law and representation at the personal hearing.
First appeal
Grounds of appeal, pre-deposit computation, filing and hearings before the Appellate Authority.
GST Appellate Tribunal (GSTAT)
Tribunal appeal drafting and representation, with our legal associates where needed.
Why clients choose us
A GST practice, not a filing counter
GST is our main work
Our founder built her career in indirect tax, including at a multinational. Notices, reconciliations and appeals are what we do every day, not an add-on to return filing.
Replies built on your numbers
Most demands start from data mismatches. We reconcile GSTR-1, GSTR-3B, GSTR-2B and your books line by line before writing a word, so the reply rests on evidence.
Close to you, wherever your officer is
We act before GST officers across Mumbai, Navi Mumbai and Raigad, with associates for in-person appearances, and handle portal hearings online.

I have received a GST notice. What should I do first?
Do not ignore it and do not reply in a hurry. Note the form number, the section and the reply date, then download the notice and any attachments from the GST portal under Services → User Services → View Additional Notices/Orders. Send it to us with your returns for the period and we will tell you what it means.
Do you only handle GST litigation?
GST litigation and advisory is our core practice. We also handle GST compliance, income tax, audits, RERA and business support for clients who want one firm for their tax work. See all services.
Do you handle GST notices for businesses in Mumbai and Navi Mumbai?
Yes. A large share of our work is for businesses registered in Mumbai, Navi Mumbai and Raigad, whether with Maharashtra State Tax or a CGST commissionerate. Replies are filed on the GST portal, many hearings are held online, and our associates attend in person where needed. See our Mumbai and Navi Mumbai pages.
How are your fees decided?
It depends on the notice type, the number of issues, the amount in dispute and the stage. We quote after reading the notice, before any work starts.
