GST Return Filing Charges for Small Businesses in India (2026 Guide)
GST return filing charges for a small business in India typically run ₹500 to ₹1,500 per month for straightforward GSTR-1 + GSTR-3B filing under the QRMP scheme, or ₹1,500–₹4,500 per quarter as a bundled package — rising to ₹3,000–₹8,000+ per month for businesses with high invoice volume, multiple GSTINs, or e-commerce/export transactions that need extra reconciliation.
What exactly do GST return filing charges cover?
When a CA or GST practitioner quotes you a monthly or quarterly fee, it almost never means “just clicking submit on the portal.” A realistic GST filing charge covers:
- Reconciling your sales register against GSTR-2B (auto-drafted input tax credit) before filing
- Preparing and filing GSTR-1 (outward supplies) and GSTR-3B (summary return + tax payment)
- Checking HSN/SAC codes and GST rates on new products or services
- Computing the tax payable and generating the PMT-06 challan
- Basic query handling if the department raises a mismatch notice
Anything beyond this — full-scale bookkeeping, e-invoicing integration, GSTR-9 annual return, or representing you in a scrutiny notice — is usually billed separately. This is the single biggest reason two CAs quote wildly different numbers for what sounds like “the same service”: one number is filing-only, the other bundles reconciliation and support.
How much do small businesses actually pay, by category?
| Business profile | Typical monthly/quarterly charge | What’s usually included |
|---|---|---|
| Nil or very low turnover (under ₹20 lakh) | ₹300–₹800/month | GSTR-1 + GSTR-3B filing only, minimal reconciliation |
| Small trader/service provider (QRMP, turnover ≤ ₹5 crore) | ₹500–₹1,500/month or ₹1,500–₹4,500/quarter | Filing + basic ITC reconciliation |
| Growing business, monthly filer (turnover > ₹5 crore) | ₹1,500–₹4,000/month | Monthly GSTR-1, GSTR-3B, ITC reconciliation, notice handling |
| E-commerce seller / multi-state GSTIN | ₹3,000–₹8,000+/month | Multi-GSTIN filing, TCS reconciliation, higher invoice volume |
| Annual return add-on (GSTR-9/9C) | ₹3,000–₹25,000 one-time | Depends on turnover slab and audit requirement |
These are indicative market ranges based on common small-business engagements, not fixed government rates — the GST law itself sets no filing fee (that is separate from the CA’s professional fee). Always get the scope written down before agreeing to a number.
Which GST return do you actually need to file, and how often?
Most small businesses only deal with two return forms. GSTR-1 reports your outward supplies (sales) and is due either monthly (11th of the next month) or quarterly under QRMP (13th of the month after the quarter). GSTR-3B is the summary return where you declare total tax liability and pay it — due monthly on the 20th, or quarterly on the 22nd/24th depending on your state category. Businesses under the QRMP scheme (turnover up to ₹5 crore) file GSTR-1 and GSTR-3B quarterly but still pay tax monthly via a PMT-06 challan — this is exactly the setup most small businesses’ CA fees are quoted against.
Composition scheme dealers file a simpler quarterly CMP-08 statement plus an annual GSTR-4, which usually costs less than the regular scheme because there’s no invoice-level ITC reconciliation involved.
What happens if you delay or skip a GST return?
Late filing isn’t just an inconvenience — it compounds fast. A late GSTR-1 or GSTR-3B attracts a late fee of ₹50/day (₹25 CGST + ₹25 SGST), capped at ₹10,000, plus 18% per annum interest on any unpaid tax from the due date until payment. For a nil return, the late fee is reduced to ₹20/day, capped at ₹500. This is exactly why most small businesses find it cheaper to pay a CA a modest monthly fee than to risk a missed due date — one delayed filing with real tax liability can cost more in interest than a full year of filing fees.
How do you choose the right CA for GST filing without overpaying?
A few practical checks before you commit to a monthly retainer:
- Ask exactly what’s included — filing only, or filing plus reconciliation and notice support?
- Match the fee to your invoice volume, not a flat number — 20 invoices/month and 500 invoices/month shouldn’t cost the same.
- Confirm the annual return (GSTR-9/9C) is priced separately so it doesn’t show up as a surprise.
- Check responsiveness — a CA who replies within a day matters more near a due date than one who is ₹200 cheaper.
- Get at least 2–3 quotes before deciding — filing charges for an identical profile can genuinely vary 2–3x between practitioners in the same city.
This last point is where most small businesses lose money without realising it — accepting the first quote from a CA a friend mentioned, without any comparison. A five-minute conversation with two or three practitioners, comparing exactly what each fee includes, usually saves more over a year than the filing fee itself costs.

Frequently asked questions
How much does GST return filing cost per month for a small business? For most small businesses on the QRMP scheme (turnover up to ₹5 crore), CAs typically charge ₹500–₹1,500 per month or ₹1,500–₹4,500 per quarter for GSTR-1 and GSTR-3B filing, depending on invoice volume and whether the CA also handles reconciliation and notices.
Is GST return filing mandatory even with nil sales? Yes. A NIL GSTR-3B or GSTR-1 must still be filed for every period the GSTIN is active, even with zero sales and zero purchases. Skipping a nil return still attracts a late fee, though it is capped lower (₹20/day, max ₹500) than a return with tax liability.
Can I file GST returns myself without a CA? Yes, technically — the GST portal lets any registered taxpayer file directly. In practice, most small businesses use a CA or GST practitioner once invoice volume grows past a handful a month, mainly to avoid ITC mismatches, wrong HSN codes, and missed due dates that trigger interest at 18% per annum.
Why do GST filing charges vary so much between CAs? The headline number usually covers only the return filing itself. What changes the final bill is whether the fee also includes bookkeeping/reconciliation, e-invoicing setup, responding to GST notices, annual return (GSTR-9) prep, and the number of GSTINs or states involved — always confirm exactly what’s included before comparing two quotes.
