TallyPrime MCA21 Integration - Auto XBRL for AOC-4 & MGT-7

Every private limited, public limited, and OPC in India files annual returns with the MCA (Ministry of Corporate Affairs) — AOC-4 for financial statements and MGT-7 for the annual return. Companies with paid-up capital of Rs 5 crore or more, turnover of Rs 100 crore or more, listed companies, and subsidiaries of listed companies must file AOC-4 in XBRL format tagged against the Ind-AS or Indian GAAP taxonomy. The manual workflow is painful: export Tally trial balance to Excel, manually map every ledger to an XBRL element in the MCA taxonomy (~2,500 elements in the Ind-AS Commercial and Industrial taxonomy), fill the disclosures, run the MCA XBRL validation tool, fix errors, and upload the instance document to the MCA21 V3 portal.

Company Secretary (CS) firms managing multi-client portfolios spend 3-5 days per client per filing cycle on this. A CS firm managing 200 clients spends the better part of a quarter on manual XBRL work every year. Individual companies filing for themselves have it easier only because they file once — but the mapping effort is the same, and mistakes at this stage create MCA queries that take months to resolve.

This connector automates the entire cycle. Tally trial balance is pulled via the standard Tally API. Every ledger auto-maps to an XBRL element using a pre-built mapping table for the Ind-AS Commercial and Industrial taxonomy (and the Indian GAAP taxonomy for smaller companies). Mandatory disclosures (director details from MCA master, related party transactions from Tally cost centres, contingent liabilities from Tally provisions, segment reporting for listed entities) are pre-populated from your Tally data with CS-guided override capability. The XBRL instance document is generated per the current MCA schema, validated against the MCA XBRL validation tool, and uploaded to the MCA21 V3 portal via the MCA API. SRN (Service Request Number) is written back to a Tally custom field for audit trail.

MGT-7 (annual return with shareholding, director details, meetings, and share capital movements) is generated from Tally + MCA master data. Share capital movements (allotments, buybacks, ESOP allotments) are picked up from the Tally share capital ledger and cross-checked against MCA master data — if the two disagree, a warning surfaces for CS review before filing.

The connector is purpose-built for CS firms — a multi-client dashboard shows the filing status of every client under management, with deadlines, filing status (draft, validated, filed, SRN issued), and pending queries from the MCA. CS firms can bulk-process filings across 50-500 clients per cycle without leaving the Tally + MCA workflow. Digital signature (DSC) integration is supported per authorised signatory — when the CS confirms filing, the DSC is applied to the instance document and uploaded to MCA21 V3 in the same flow, no manual DSC dongle handling per client per filing.

Supported forms: AOC-4 XBRL (Ind-AS + Indian GAAP), AOC-4 CFS (consolidated financial statements), AOC-4 non-XBRL (small companies), MGT-7 (annual return), DPT-3 (deposits), and CRA-4 (cost audit report where applicable).
