GST Advisory & Return Filing Services for Indian Businesses

Our GST advisory & return filing services are for Indian businesses that want a GST consultant to own registration, GST return filing, GSTR-9 / GSTR-9C annual reconciliation and GST audit support. End-to-end GST support — from registration to returns, ITC reconciliation, audits and notice handling — by an expert-led team.

Regi Tom Antony's view

GST problems usually start with a registration or invoicing choice made in a hurry. Get the registration, place of supply and invoicing set up correctly at the start; fixing input credit mismatches later is slower and costlier.

Where GST costs SMEs money

Most GST problems in growing businesses come from a few areas: input tax credit claimed when it should not be, or not claimed when it could be; mismatches between purchase records and supplier filings; wrong classification or rate; and missed obligations such as reverse charge, e-invoicing or e-way bills. GST advisory finds these before the department does.

Key compliance points

  • Registration: required once aggregate turnover crosses the threshold for your category of supply and state, and in some cases regardless of turnover, such as inter-state supply of goods or e-commerce sales.
  • Returns: GSTR-1 for outward supplies and GSTR-3B for the summary and tax payment, monthly or quarterly depending on the scheme, plus annual GSTR-9 and, above a threshold, the GSTR-9C reconciliation.
  • Input tax credit: available only if the supplier has reported the invoice and the conditions in Section 16 are met; some credits are blocked under Section 17(5).
  • E-invoicing: mandatory above a notified turnover threshold, which has been lowered several times.

Figures and timelines above reflect our understanding at the time of writing; confirm against the latest Act, Rules and notifications before relying on them.

How we work

An engagement usually starts with a GST health check: reconciliation of books with GSTR-1, GSTR-3B and the auto-drafted credit statement, a review of classification and rates for main products or services, and a check on reverse charge and blocked credits. We then fix the process, not just the return, and support you on notices and audits. Exporters should also see export of services and LUT and GST refunds.

Practical questions

Can I claim credit if my supplier has not filed?

Generally no. Credit depends on the supplier reporting the invoice, so supplier follow-up is part of monthly compliance.
