--- title: "GST returns vs Zoho Books: reconcile your refund records" description: "Prepare a service-export refund by matching books, GSTR-1, GSTR-3B, GSTR-2B and receipts. A worked example explains why their totals can differ." topic: "Reconcile your records" published: 2026-09-08 checked: 2026-09-11 order: 3 --- **Start with your filed GST returns and an invoice-level export from your books, then explain the differences between them.** For a service-export refund under LUT, your accounting balance alone does not establish the refund amount. GSTR-2B alone does not cover every type of input tax credit either. You can do this with downloaded files from Zoho Books, another accounting system or a spreadsheet. The useful result is a record of what you claimed, what supports it and what still needs correction. If your records are in Zoho, begin with [how to export invoices, bills and the GSTR-2B reconciliation](/guides/export-zoho-books-data-gst-refund/) so each source stays identifiable. ## Which record answers which question? | Record | What you use it to check | | ------------------------------------------------ | -------------------------------------------------------------------------------------------------- | | Sales register and original export invoices | Customer, invoice number/date, service, currency, value and adjustments | | Filed GSTR-1 and applicable GSTR-1A/amendments | Outward supplies reported to GST, including export invoice details | | Filed GSTR-3B | Reported outward-supply totals, ITC availed, reversals and reverse-charge liability | | GSTR-2B downloads | Supplier-reported inward documents and their statement period; compare with your purchase register | | Purchase register and original documents | What you bought, tax charged, invoice details and input/input-service/capital-goods classification | | Bank statements and applicable FIRC/BRC evidence | Export receipts, dates and their allocation to invoices | | Electronic Credit Ledger and prior claims | Available credit, movements and amounts already used or claimed | GSTR-1 contains outward-supply details; GSTR-3B reports summaries and does not perform invoice matching. A matching GSTR-3B total therefore still needs an invoice-level explanation. [GST portal: GSTR-1](https://tutorial.gst.gov.in/contextualhelp/Einv/GSTR_1.htm), [GSTR-3B FAQ](https://tutorial.gst.gov.in/userguide/returns/GSTR3B.htm). Save each source with its period, download date and status: filed return, generated statement or accounting export. GSTR-2B is downloadable in Excel/JSON; the credit ledger is downloadable in PDF/CSV. [GSTR-2B FAQ](https://tutorial.gst.gov.in/userguide/returns/FAQ_gstr2b.htm), [Credit Ledger FAQ](https://tutorial.gst.gov.in/userguide/ledgers/Electronic_Credit_Ledger.htm). ## Reconcile sales and purchases separately For **export sales**, give every invoice a row containing its books value, filed-return reference, receipt amount/date, bank-evidence reference and unresolved difference. Record credit notes and amendments beside the affected invoice. An unpaid invoice, a part-payment and an exchange-rate difference need different explanations. Use the [Statement 3 worked example](/guides/statement-3-worked-example/) to carry the invoice-to-receipt mapping into your refund preparation. For **purchases**, match domestic supplier records using GSTIN, document type, invoice number/date, taxable value and tax by head. Keep the invoice month, actual GSTR-2B period and ITC-availment period in separate columns. Then classify each row: | Finding | Next action | | ------------------------------------------------------ | ------------------------------------------------------------------------------------------------------------- | | Same invoice and tax in both sources | Check eligibility, reversals and whether it was already claimed | | Domestic invoice in books, absent from the expected 2B | Check supplier reporting, statement period and applicable IMS status; keep the difference open until resolved | | Invoice in 2B, absent from books | Obtain the original document and establish whether it belongs to your business | | Different invoice details or tax | Compare the original document and identify which record needs correction | | Credit/debit note or duplicate | Link the adjustment to the original; count the transaction only once | | Imported service under reverse charge | Reconcile its documents, tax payment and ITC separately; an absent 2B row is expected | GST's FAQ expressly says reverse-charge credit on imported services is absent from GSTR-2B and is entered through GSTR-3B tables 4(A)(2) and 3.1(d). This does **not** mean every reverse-charge transaction is absent from 2B. [GST portal: GSTR-2B FAQ](https://tutorial.gst.gov.in/userguide/returns/FAQ_gstr2b.htm). For statement-period decisions, use [which GSTR-2B period belongs in Annexure B?](/guides/annexure-b-gstr-2b-period/). ## Example: books show ₹21,600 tax, but July GSTR-3B shows ₹12,600 ITC All amounts and transactions below are invented. Assume a monthly filer, no reversals, and that the imported-service tax was paid and its eligible ITC availed in July. | Purchase | Tax recorded in books | July GSTR-2B | ITC availed in July GSTR-3B | | ----------------------------------------------------------------------- | --------------------: | -----------: | --------------------------: | | Domestic business service, matched | ₹9,000 | ₹9,000 | ₹9,000 | | Domestic business service, supplier reported late; appears in August 2B | ₹9,000 | — | ₹0 | | Imported business service under reverse charge | ₹3,600 | Not included | ₹3,600 | | **Total** | **₹21,600** | **₹9,000** | **₹12,600** | The reconciliation is **₹21,600 in books − ₹9,000 not availed in July = ₹12,600 availed in July**. The difference between July 2B and 3B is the separately supported ₹3,600 import-service credit. Keep the late domestic invoice on the pending list for the appropriate later-period review. Keep the imported-service supplier document, applicable self-invoice and tax-payment evidence with its row. CBIC separately clarified the treatment of refund credit relating to imports and reverse-charge supplies in [Circular 139/09/2020-GST, paragraph 4](https://cbic-gst.gov.in/pdf/Circular-Refund-139.pdf). **₹12,600 is the reconciled ITC figure in this example, not an automatically refundable amount.** The refund working must still establish eligible Net ITC, the turnover calculation and applicable ledger limits. See [how the refund calculation works](/guides/gst-refund-calculation-more-than-turnover/). ## What can Zoho Books help with? Zoho's GST Filing module can fetch GSTR-2B and group transactions into matched, partially matched and missing records. Its documented flow uses GST API access and OTP authorisation when required. It also supports regenerating 2B after relevant IMS changes. [Zoho Books: GSTR-2B reconciliation](https://www.zoho.com/in/books/help/gst/gstr2b-reconcile.html). Use those groups as a work queue. Check each proposed correction against the original invoice before accepting it. An accounting connection still needs the filed-return, receipt-evidence and refund-computation checks above. ## When are the records ready for the refund working? You should be able to trace every proposed amount to its source, identify its period, and explain every difference. Keep unresolved items out of the proposed eligible total until their treatment is settled. Summarise pending documents, corrections, exclusions and prior claims for the person reviewing the application. Next, transfer reviewed purchase rows using the [Annexure B worked example](/guides/annexure-b-worked-example/) and assemble the [complete refund claim pack](/guides/gst-refund-claim-contents/).
