Preparing GST returns

Prepare GSTR-1 and GSTR-3B from your entries, reconcile GSTR-2B, apply the credit rules and file.

Updated 15 October 2026

What you’ll do: take a month’s GST from your books to a filed return.

Who can do this: accountants prepare. Whoever holds the GST portal login files there and records the ARN in Books.

Steps

  1. In Dexta Books, open GST returns under Tax and pick the month (and the GSTIN, if you have branches).
  2. On GSTR-1, check your sales and download Portal JSON to upload through the GST portal.
  3. On GSTR-2B, upload the file you downloaded from the GST portal and match each line: Accept, Link to bill, or Post held input tax.
  4. Check the credit rules: Unpaid 180 days (rule 37), Rule 37A (suppliers who didn’t file GSTR-3B; Reverse the credit), and the rule 42 card on GSTR-3B for common credit.
  5. On GSTR-3B, click Post set-off entry. On Payment, click Make challan for anything due in cash, then Record payment once paid.
  6. File the return on gst.gov.in with your DSC or EVC. Back on Filing, click Filed on the portal and enter the ARN the portal gave you.

Good to know

  • Books doesn’t file returns on the portal for you yet: it prepares them, makes the JSON and keeps the ARN.
  • Each return shows Not started, Saved, Filed (with the ARN) or Not accepted.
  • The same page has GSTR-9, DRC-03, ISD (GSTR-6), ITC-04 and export and IGST refunds.
  • E-invoices and e-way bills go through your Masters India account. See E-invoices and bank feeds.
  • Close the month with Close on the GSTR-3B tab once it’s filed.
