GST returns: online CA-assisted vs doing it yourself (India)
GST returns are free to file on the government portal, so the real question is not price but time, accuracy and risk. For a small trader with a handful of invoices, filing GSTR-1 and GSTR-3B each period is routine. For a business with purchases to reconcile, input tax credit to protect, and penalties for a slip, a missed match or a late filing can cost far more than any fee. This guide explains exactly when doing it yourself is fine and when assisted help pays for itself.
- No government fee: GST returns are free to file on gst.gov.in.
- DIY is fine for low-volume, simple businesses comfortable with the portal and due dates.
- Most trouble comes from input tax credit mismatch, GSTR-1 vs GSTR-3B gaps, and late filing.
- Assisted helps when you have purchase volume, sell across states, or keep missing deadlines.
- Claw Tax: a verified CA reconciles and files, a reviewer checks, from Rs 799 a month, free government fee.
- Not tax advice: confirm current rules; a professional handles the specifics.
01You can file your returns yourself for free
There is no government fee to file a GST return, and the whole process runs on gst.gov.in. A regular taxpayer files outward supplies in GSTR-1 and a summary with payment in GSTR-3B, either monthly or quarterly under the QRMP scheme, and an annual return (GSTR-9) where applicable. The portal shows your auto-drafted input tax credit in GSTR-2B to match against your purchases.
Do it yourself when your case is straightforward: a small number of invoices each period, few or simple purchases, no unusual credits, and you are comfortable with the portal and the due dates. If that describes you, there is no reason to pay.
This is a decision guide, not tax advice
GST rules, return forms and due dates change, and section 74A now governs demands for FY 2024-25 onward. Confirm the current process on the portal, and let a qualified professional handle the specifics where your case is not simple.
02Where DIY return filing goes wrong
Most GST trouble comes from a small set of avoidable mistakes that pile up over months.
- Input tax credit mismatch: claiming credit that does not appear in your GSTR-2B because a supplier did not file, which can be reversed with interest later.
- GSTR-1 and GSTR-3B do not tie out: the outward supplies you report and the summary you pay on diverge, which triggers a system notice.
- Late filing: a late return attracts a late fee per day and interest on unpaid tax, and it blocks the next period until it is cleared.
- Wrong tax head or place of supply: charging CGST and SGST where IGST applied, or the reverse, which is painful to correct.
- Missing a reverse-charge or RCM entry: leaving out a liability you were supposed to self-account for.
None of these are hard to avoid once you know them, but they compound. A single unreconciled month can take hours to untangle a year later.
03When CA-assisted filing is worth it
Assisted filing earns its fee when volume, credit or deadlines raise the stakes.
- You have real purchase volume and want input tax credit reconciled against GSTR-2B every period, not at year end.
- You sell across states or on marketplaces, so place of supply and tax head need to be right each time.
- You keep missing due dates and the late fees and blocked periods are costing more than a service would.
- You want the annual return and reconciliation (GSTR-9 and 9C) prepared properly, not rushed at the deadline.
- You want someone to answer a notice if a mismatch or a section 74A demand comes.
In these cases, a professional filing each period and watching your credit is usually cheaper than the interest, late fees and lost credit of getting it wrong.
04Cost and effort compared
Set the two routes side by side on the things that actually differ.
| Factor | Do it yourself | CA-assisted (online) |
|---|---|---|
| Government fee | None | None (service fee on top) |
| Who prepares it | You | A verified professional |
| Input tax credit reconciliation | You match GSTR-2B | Reconciled for you each period |
| Risk of a mismatch notice | Higher with volume | Lower, with a reviewed filing |
| Handling a late fee or notice | You manage it | The professional handles it |
| Service cost | Zero | Fixed, published (for example from Rs 799 a month) |
| Best for | Low-volume, simple cases | Volume, multi-state, or messy credit |
05How Claw Tax helps
Claw Tax and Accounts is an online tax, GST and accounting service for India that connects you with a verified chartered accountant at a fixed, published price, with a Claw reviewer checking every filing before it is submitted.
For GST returns, you pick the service or book a free 20-minute call, pay the fixed price (GST returns from Rs 799 a month), and a verified partner CA reconciles your input tax credit against GSTR-2B, prepares GSTR-1 and GSTR-3B, and files on time. A Claw reviewer checks the figures before submission, you get reminders before each due date, and if a mismatch or notice comes, the professional handles it. See the current service and price at clawlaw.in/tax.
The same decision comes up for other filings: see TDS returns: CA-assisted vs doing it yourself. And if a GST or income tax notice does arrive, replying to a notice: CA-assisted vs doing it yourself covers that decision.
06Frequently asked questions
Is there a government fee to file GST returns?
No. Filing GST returns is free on the government portal. The only charges are a late fee and interest if you file after the due date, and any service fee you choose to pay a professional or platform. The filing itself carries no government charge.
Can I file my GST returns myself?
Yes. You can file GSTR-1 and GSTR-3B, and the annual GSTR-9 where it applies, yourself on gst.gov.in, matching your input tax credit against the auto-drafted GSTR-2B. It is practical for a low-volume business with simple purchases. It gets harder with real purchase volume, sales across states, or credit that needs careful reconciliation each period.
What is input tax credit reconciliation and why does it matter?
Input tax credit (ITC) is the GST you paid on purchases that you can set off against the GST you collect on sales. You can generally only claim credit that appears in your GSTR-2B, which depends on your suppliers filing correctly. Matching your purchases against GSTR-2B each period protects your credit and avoids a reversal with interest later, which is why reconciliation is the core of assisted GST work.
What happens if I file a GST return late?
A late return attracts a late fee for each day of delay and interest on any unpaid tax, and it blocks you from filing the next period until the earlier one is cleared. The amounts are capped and notified, so confirm the current figures, but the practical cost is the blocked periods and the interest, which is why consistent on-time filing matters.
What does a fixed monthly GST service cost?
The government fee is zero; you pay only a service fee. Services publish monthly fees, for example Claw Tax lists GST returns from Rs 799 a month. Always confirm the current price and what the fee includes, such as reconciliation, both returns, and handling a notice, before you buy.
Do I need help with the annual return GSTR-9?
The annual return (GSTR-9), and the reconciliation statement (GSTR-9C) where it applies, pull together the whole year, so they expose any gaps left during the year. If your monthly filings were clean, it is manageable; if there were mismatches, it is where they surface. Many businesses that self-file monthly still take help for the annual return and reconciliation.
