Features of GSTR-1 Filing in Mocha Accounting

Auto-Classify Every Invoice into the Correct GSTR-1 Table — B2B, B2CL, B2CS, Exports and More

GSTR-1 has multiple tables, each covering a different category of outward supply — B2B invoices to registered recipients in Tables 4A/4B/6B/6C, large inter-state B2C invoices in Table 5, small B2C invoices consolidated state-wise in Table 7, nil-rated and exempt supplies in Table 8, exports in Table 6A, and credit/debit notes in Tables 9B. Mocha Accounting reads the supply type, recipient GSTIN, invoice value and place of supply from each recorded transaction and assigns it to the correct table automatically — no manual sorting required.

Handle Amended Outward Supplies — Prior Period B2B, B2C and Export Amendments in One Place

When an invoice filed in a previous period needs correction — a wrong GSTIN, a tax rate error, or a value revision — the amendment must be declared in the current period's GSTR-1 under Tables 9A and 10. Mocha Accounting tracks every amendment as it is recorded against the original invoice, links the revised values to the original filing period, and places each amended invoice in the correct table automatically — 9A for amended B2B, 9A for amended B2C Large, 10 for amended B2C Small, and 9A for amended export invoices. Your amendment history is always complete and traceable without manual cross-referencing to prior returns.

GSTR-1 HSN-wise summary and document summary

Advances Received, HSN Summary and Document Summary — All Tables Covered, Auto-Generated

Beyond invoices, GSTR-1 requires three additional categories. Table 11 captures advances received on which tax liability arises (11A) and advances adjusted against invoices raised (11B) — ensuring no advance goes unreported. Table 12 generates the HSN-wise summary automatically from your invoice line items — aggregating taxable value and tax by HSN code, with digit-count validation against your turnover threshold. Table 13 compiles the document summary — a count of every invoice, credit note, debit note, advance receipt and refund voucher issued during the period, including cancelled documents. All three are generated from your existing records with no additional data entry.

Tax Liability Summary, Compliance Notice and Portal-Ready Export — All in One Report

Once all tables are compiled, Mocha Accounting generates the GSTR-1 Tax Liability Summary — Taxable Value, IGST, CGST + SGST and Total Tax Liability for the period — matching the exact format of the portal report. An in-system compliance notice flags the due date, overdue status, late fee applicable, and the November deadline for prior-year amendments, so your team is never caught out by a deadline. When everything checks out, a single click exports the GSTN-compliant JSON for direct upload to the portal — no reformatting, no re-entry.

Why Choose Mocha Accounting for GSTR-1 Filing

Your Invoices Are Your GSTR-1 — No Double Entry

Compiled from the Same Invoices That Power Your Books

Every sales invoice, credit note, debit note, advance receipt and export invoice you record in Mocha Accounting feeds your GSTR-1 automatically. There is no separate compliance module to fill in and no risk of your return diverging from your books. The invoice you raise for your client is the invoice that appears in the correct table of your next GSTR-1 — exactly as recorded.

Every Table Covered — Including Advances, Amendments and E-Commerce Supplies

Automatic Table Classification with Pre-Filing Validation

Mocha Accounting covers all 15 GSTR-1 tables — from B2B invoices and exports through to amended supplies, advances received and adjusted, HSN summary, document summary, and e-commerce operator supplies. Most accounting tools stop at the main invoice tables; Mocha handles the full return so your filing is complete.

GSTR-1 Data Flows Directly into GSTR-3B — Consistency Checked Before Filing

Portal-Ready JSON in a Single Click

Once your GSTR-1 is compiled, the outward supply totals feed directly into your GSTR-3B computation. Before you export GSTR-3B, the system cross-checks its outward supply figures against your GSTR-1 for the same period — so discrepancies are flagged and resolved before filing, not discovered when the portal detects the mismatch.

Frequently Asked Questions

GSTR-1 is a monthly or quarterly return that every GST-registered taxpayer must file, declaring all outward taxable supplies — sales invoices, credit notes, debit notes, export invoices, and advances received. Monthly filers with turnover above ₹5 crore must file by the 11th of the following month. Taxpayers under the QRMP scheme file quarterly by the 13th of the month following the quarter, with monthly IFF submissions for B2B invoices in the first two months.
Mocha Accounting covers all 15 GSTR-1 tables. Tables 4A/4B/6C for B2B and SEZ invoices, Table 5 for large B2C inter-state invoices, Table 7 for small B2CS invoices (state-wise summary), Table 8 for nil-rated and exempted supplies, Table 6A for export invoices, Tables 9B/9B for credit and debit notes (CDNR and CDNUR), Tables 9A and 10 for amendments, Table 11A/11B for advances, Table 12 for HSN summary, Table 13 for document summary, and Tables 14/15 for e-commerce operator supplies. Every table is populated automatically from your recorded transactions.
For monthly filers, GSTR-1 is due on the 11th of the following month. For quarterly QRMP filers, it is due on the 13th of the month following the quarter. Late filing attracts a fee of ₹50 per day (₹20 per day for nil returns). Under Section 37(4) of the CGST Act, GSTR-1 for the current period cannot be filed if the previous period's return is still pending. Amendments to invoices from a prior financial year must be made before 30th November of the following financial year.
When you amend an invoice that was included in a previously filed GSTR-1, Mocha Accounting links the amendment to the original invoice, records the original filing period, and places it in the correct amendment table — 9A for amended B2B invoices, 9A for amended B2C Large invoices, 10 for amended B2C Small invoices, and 9A for amended export invoices — in the current period's GSTR-1. The amendment history is maintained automatically with no manual cross-referencing to prior returns.
Yes. The outward supply totals from your compiled GSTR-1 feed directly into your GSTR-3B computation. Before you export your GSTR-3B, Mocha Accounting runs a consistency check comparing the GSTR-3B outward supply figures against the corresponding GSTR-1 totals for the same period. Any discrepancy is surfaced before filing — preventing the common scrutiny trigger of mismatched outward supply declarations across GSTR-1 and GSTR-3B.
Mocha Accounting prepares, validates and exports your GSTR-1 as a GSTN-compliant JSON file. You or your CA then upload that JSON to the GST portal to complete the filing. This keeps you in control of the final submission while removing all the manual, table-by-table data entry that typically precedes it. The Export Options button in the report gives you the portal-ready file in one click.
