Before you commit

Is GST Return Filing the right next step for you?

The commercial facts first — who the work is for, what it costs, how long it takes and what you have to arrange. Everything below is specific to gst return filing, not a generic CA brochure.

The short version

  • GST Return Filing is normally taken up by every GST-registered business.
  • Starts at ₹999/month. The number moves with entity type, volumes and the state of your records; statutory and portal charges are paid at actuals.
  • Timeline: Monthly / quarterly — counted from a complete document set, with third-party processing time on top.
  • Plan for 4 core documents and 5 defined stages, starting with Sales & purchase invoices and GST login.

Who it is built for

Every GST-registered business — that is who this page is written for. If your position is materially different, the scope and the fee change with it, so tell us the facts rather than relying on the ranges here.

What usually triggers it

A new line of business, a marketplace or bank requirement, a notice in the inbox or simply the filing calendar is what brings this forward.

What the work hinges on

Returns and applications are only as good as the invoice, bank and tax-credit data sitting behind them. For GST Return Filing, that means 4 core documents and a clear picture of your entity and activity.

What you are left with

No late fees or penalties, maximum ITC claims, clean compliance rating. This is recurring work: the calendar and the reconciliation habit matter more than any single filing.

Scope

What GST Return Filing includes — and what it doesn't

Quotes are only comparable when the deliverables and the exclusions are written down. This is the full picture of what you are buying, what you supply and what sits outside the fee.

What the engagement covers

  • A scoping conversation first, so the document list, the fee and the timeline are agreed before work starts
  • Preparation and internal review of every form, schedule or draft GST Return Filing needs
  • Submission and tracking through to acknowledgement or certificate
  • Replies to queries raised while the matter is being processed
  • A named chartered accountant as your point of contact, on phone, email or WhatsApp

Documents you arrange

  • Sales & purchase invoices
  • GST login
  • Bank statements
  • Expense details

What you end up with

  • No late fees or penalties
  • Maximum ITC claims
  • Clean compliance rating
  • Working papers, acknowledgements and certificates handed over in one place

Outside this scope

  • Government, registry and portal charges, which are paid at actuals
  • Corrections to earlier periods or filings, quoted separately once we have seen them
  • Processing time at the department or registry, which no adviser controls
  • Any outcome that rests on a regulator's decision — we prepare and represent, we do not promise approvals

Make the monthly handover boring

Agree a fixed cut-off for sales and purchase data, send bank statements for the same period, and keep credit notes and expense bills in the same batch. A predictable handover is what keeps filings off the deadline.

How it runs

The GST Return Filing process, stage by stage

5 stages, each one confirmed with you before the next begins. You approve the working before anything is submitted in your name.

  1. 1

    Data collection

    We confirm what GST Return Filing needs in your case and agree the document list, the fee and who signs, before any work starts.

  2. 2

    GSTR-2B reconciliation

  3. 3

    GSTR-1 filing

  4. 4

    GSTR-3B & tax payment

  5. 5

    Annual return

    Handover closes the engagement: final documents, acknowledgements and working papers in one place, with a note on what the next cycle will ask for.

Two things decide the timeline

How quickly the document set is complete, and how quickly queries are answered once the matter sits with the department or registry. The published turnaround assumes the first of those is sorted on day one.

What typically delays GST Return Filing

Differences between your books, your returns and the statements already held against your PAN or GSTIN are what turn routine filing into correspondence. We check for exactly this before anything is submitted, because a query answered late costs more time than the filing itself.

Compare

Three ways businesses get this filed

The question is rarely whether a filing can be submitted. It is who reconciles the data, who answers the department, and who still has the working papers a year later.

This comparison is general guidance on how the work is usually structured. Which option applies to you depends on your facts, so treat it as a starting point for a conversation rather than advice.

Avoid these

Where GST Return Filing usually goes wrong

Most delays are not technical. They come from paperwork that disagrees with itself, decisions taken too late, or a filing treated as the end of the matter.

Filing from sales data alone

Claiming credit without reconciling against the auto-populated purchase statement means claiming what a supplier may never have reported. That gap is found later, with interest attached.

Summary and invoice data disagreeing

Treating the summary return as the whole filing leaves invoice-level data inconsistent with it. The mismatch does not disappear; it surfaces at reconciliation or audit.

Not chasing late suppliers

Credit follows what your suppliers report. Following up with them is part of the monthly routine, not an afterthought once the return is already filed.
