What Is GST Return Filing?
Once you hold a GSTIN, filing GST returns becomes a recurring duty, not a one-time task. Every registered taxpayer must report sales, purchases, tax collected and input tax credit to the GST portal at regular intervals. The returns are small in number but unforgiving in detail: a wrong invoice, a missed due date or a mismatch with your supplier's data can mean late fees, interest, blocked credit or a notice from the department.
For most regular taxpayers the core filings are GSTR-1, which lists your outward supplies invoice by invoice, and GSTR-3B, the summary return in which you declare liability, claim input tax credit and pay the tax. Composition taxpayers, e-commerce operators, TDS deductors and annual filers each have their own forms and dates. Even a business with no sales in a month still has to file a nil return.
Taxvio's CA-assisted team takes this off your plate. We prepare and file GSTR-1 and GSTR-3B, reconcile your purchase invoices against the auto-drafted statement, calculate late fee and interest where a deadline was missed, and monitor your compliance calendar so nothing slips. You get a fixed quote before we begin and one point of contact for every period.
Why Professional GST Return Filing Pays Off
Never miss a due date
A tracked calendar and early reminders keep every return on time, avoiding daily late fees and interest.
Protect your input credit
Reconciliation makes sure the credit you claim is supported, so it is not reversed or questioned later.
Accurate figures
Rates, codes and totals are checked by a CA before filing, because a filed GSTR-3B generally cannot be revised.
Fewer notices
Clean, consistent returns reduce mismatches that trigger departmental notices and queries.
Early warning on issues
Supplier non-filing, credit gaps and portal flags are raised with you before they become costly.
A clean GST record
A regular filing history supports loans, tenders and big-customer onboarding, which often ask for it.
GST Returns You May Need to File
The returns you file depend on your registration type and filing option. Regular taxpayers file GSTR-1 and GSTR-3B, composition taxpayers file CMP-08 and an annual return, and most registrants also file an annual return. Tap a form for its purpose. Due dates below are the general ones; the government extends or changes them by notification, so our team confirms the current dates for your registration.

What Does a Missed GST Return Cost?
Delay is expensive in GST. A late fee runs every day after the due date, and interest is charged on any tax paid late. Use this indicator to see how fast it adds up. It is a rough estimate for a GSTR-3B before any caps or relief notifications; the exact amount depends on the return, turnover and current rules, which our CA will confirm.

What does it cost?
Our fee depends on your filing frequency, the number of invoices and whether you need reconciliation or backlog work. You receive a written quote before we start, with no add-ons introduced later. Late fees and interest, where applicable, are payable to the government and are shown separately.
🔁
Monthly or quarterly?
Eligible taxpayers can opt for the quarterly return scheme with monthly payment of tax. It reduces the number of filings but does not remove the duty to pay tax each month. We advise which option fits your business.
Reconciliation, Credit Checks & Common Mistakes
Most GST problems come from mismatches, not from the return itself. Reconciling your records with the auto-drafted credit statement before filing is the single most effective way to protect your input tax credit and avoid notices. This is what our team checks every period.
Match purchases to GSTR-2B
Compare each purchase invoice with the auto-drafted statement to confirm the supplier has reported it.
Chase supplier mismatches
Where a supplier has not filed, we flag it so you can follow up before the credit is at risk.
Check eligibility of credit
Not every GST paid on purchases is claimable; we apply the rules and block credit that is ineligible.
Reconcile books with returns
Totals in your books are matched with the returns filed, so annual filings later are clean.
Fix errors in the right period
Where a correction is needed, we use the permitted amendment route within the time limits.
Mistakes that cost businesses money
Filing nil when there were sales
Skipping or under-reporting invoices can lead to demand notices, tax and interest.
Claiming credit not shown in GSTR-2B
Credit without matching supplier data is a common reason for reversal and interest.
Wrong tax rate or HSN code
Using the wrong rate understates or overstates tax and invites questions later.
Paying tax late but filing on time
Interest runs on the unpaid tax from the due date even if the return was filed in time.
Ignoring portal notices
Reminders and notices have reply windows; silence can escalate the matter.

GST Return Filing — Frequently Asked Questions
GST return filing is the periodic reporting of your sales, purchases, tax collected and input tax credit on the GST portal. Every registered taxpayer must file returns on time, and the main ones for regular taxpayers are GSTR-1 (outward supplies) and GSTR-3B (summary return and tax payment).
GSTR-1 reports the details of your outward supplies, invoice by invoice, and feeds your customers' purchase records. GSTR-3B is a summary return in which you declare your total tax liability and input tax credit and pay the tax. Both are needed for a regular taxpayer in each period.
For monthly filers, GSTR-1 is generally due on the 11th of the following month and GSTR-3B on the 20th. Taxpayers under the quarterly (QRMP) scheme have different due dates. Dates can change by notification, so our team confirms the current dates for your registration.
Yes. A registered taxpayer must file even when there is no business in the period, using a nil return. Skipping a nil return can still attract a late fee and may block future filings, so it should never be ignored.
A late fee accrues for every day of delay after the due date, at a lower rate for nil returns, subject to caps that depend on the return and your turnover. Interest is also charged on any tax paid late. Use the estimator on this page for an indication; our CA confirms the exact figure.
Persistent non-filing can lead to notices, blocking of e-way bill generation, restrictions on filing GSTR-1 and, eventually, cancellation of registration by the department. Pending dues and returns still have to be cleared, so it is better to regularise early.
Reconciliation compares your purchase records with the auto-drafted statement of input tax credit (GSTR-2B) so that you claim only the credit that is actually available. It protects you from claiming ineligible credit and from later notices and interest.
Eligible taxpayers can opt for the quarterly return scheme with monthly payment of tax (QRMP), which reduces the number of return filings. Eligibility depends on turnover and on opting through the portal, and our team can advise whether it suits you.
Yes. We review your portal status, prepare all pending returns in the right order, calculate the late fee and interest and tell you the total before we begin. Clearing the backlog early also limits further late fee and avoids cancellation proceedings.
Your sales invoices, purchase invoices, credit and debit notes, expense bills with GST, and bank statements. If you use accounting software we can work from its exports. Our checklist on this page lists what to share.
Corrections are possible through amendment tables in later returns and subsequent periods, subject to the time limits in the law. A GSTR-3B generally cannot be revised once filed, so the figures must be right the first time, which is why we review before filing.
