GST Return Filing: GSTR-1, GSTR-3B and Annual Return Support
Reconcile sales and purchases with GSTR-2B and file your GST returns on time so credit and compliance stay clean.
Get Started Today
GST return filing is the recurring reporting of your outward supplies, input tax credit and tax payment on the GST portal, and every registered taxpayer has to do it, including those with no sales in a period. Monthly or quarterly returns such as GSTR-1 and GSTR-3B, along with the annual return where applicable, must agree with your books and with what your suppliers report. Our team prepares the returns from your sales and purchase data, reconciles credit with GSTR-2B, pays the tax liability and keeps a record of every acknowledgement so that notices are easier to answer.

How It Works
Confirm your filing profile
We check your registration details, return frequency, whether you are in the quarterly scheme or composition, and whether e-invoicing or e-way bill rules apply, so each period uses the right return.
Receive sales and purchase data
You send invoices, credit and debit notes and purchase data as an export from your accounting software or a simple sheet. We check for missing invoice numbers, wrong GSTINs and place of supply errors.
Prepare and file GSTR-1
We prepare the statement of outward supplies with correct HSN, tax rates and place of supply, share the summary for your approval and upload it, since GSTR-1 data drives your customers’ credit.
Reconcile credit with GSTR-2B
We compare your purchase register with GSTR-2B, identify invoices not yet reported by suppliers, ineligible or blocked credits and reversals, and decide what credit can safely be claimed this period.
Compute liability and file GSTR-3B
We set off available credit against tax payable, tell you the cash amount to deposit, create the challan and file GSTR-3B after payment, then send you the acknowledgement and working summary.
Annual return and notice follow-up
At year end we reconcile the returns with your books for the annual return, point out differences that need rectification and help you reply if the department raises a query or discrepancy notice.
Documents Required
- GSTIN and portal access details or authorisation for our team to file on your behalf
- Sales register or invoice-wise export for the return period, including exports and exempt supplies
- Purchase register with supplier GSTIN, invoice number, date, taxable value and tax amount
- Credit notes, debit notes and amendments issued or received during the period
- E-invoice IRN data and e-way bill details, if applicable to your turnover
- Bank statements, to match tax payments and receipts
- Details of any reverse charge purchases, imports and inward supplies from unregistered persons
- Previous returns, challans and the ledger balances for electronic credit and cash
Timeline and Fees
Indicative timeline: Returns are prepared and filed ahead of each statutory due date, which varies by return type and filing frequency and can be changed by notification. Annual return work is usually done after the books for the year are final.
Professional fee: The fee depends on the number of GSTINs, monthly invoice volume, return frequency, whether reconciliation is needed and the state of your books. Contact our team with a short description of your business for a written quote.
What Can Go Wrong if This Is Missed or Done Incorrectly
- Late fees accrue for each day a return is overdue, and interest applies on tax paid late
- Claiming credit not supported by GSTR-2B or by a valid invoice can lead to reversal, interest and notices
- Mismatches between GSTR-1, GSTR-3B and your books are a common trigger for departmental scrutiny
- Continued non-filing can restrict e-way bill generation and may lead to cancellation of the registration
Frequently Asked Questions
What is the difference between GSTR-1 and GSTR-3B?
GSTR-1 is the detailed statement of your outward supplies, invoice by invoice, which your customers’ credit depends on. GSTR-3B is the summary return where you declare totals, claim input tax credit and pay the tax. The two must be consistent, because the department compares them and raises queries on differences.
What happens if I do not file my GST returns on time?
A per-day late fee applies, interest runs on tax that was paid late, and the portal can restrict further filings or e-way bill generation if returns stay pending. Prolonged non-filing can lead to cancellation proceedings. Because fee and interest provisions are updated by notification, check the portal or ask us for the current position.
Do I have to file a GST return if I had no sales this month?
Yes. A registered person must file the due return even when there is no turnover, which is called a nil return. Skipping nil returns still triggers late fees and a compliance default on your record. Nil returns are simple to file, but they must be filed on time like any other return.
Why must I reconcile my purchases with GSTR-2B?
GSTR-2B shows the credit available to you based on what your suppliers reported. Claiming credit that does not appear there, or missing credit that does, creates mismatches and disputes. Reconciling each period lets you chase suppliers early, hold back doubtful credit and claim only what the law permits.
What is the quarterly return scheme and who can use it?
Eligible small taxpayers can file GSTR-1 and GSTR-3B quarterly and pay tax monthly, with an option to upload invoices each month through the invoice furnishing facility. Eligibility depends on turnover and conditions notified by the government, so we check the current rules before recommending it for your business.
Do I still need an annual GST return?
Most regular taxpayers have an annual return and, above certain turnover levels, a reconciliation statement to certify, although relief is sometimes given to smaller taxpayers by notification. The annual return is the final chance to correct differences between your books and returns, so we prepare it carefully even where filing is optional.
