GST मिलान sits inside the GSTR-9 / 9C Working Paper, not as a separate task. The annual return is the destination; the मिलान is the path. Upload every quarter of GSTR-2A, every monthly 2B, every 3B return. CORAA merges them and reconciles quarter by quarter.
TDS and TCS मिलानs sit as tabs inside Form 3CD. Form 26AS PDFs and 27EQ FVU files ingest through multi-file upload. खंड-wise TDS totals populate Form 3CD Clause 34(a) automatically; variances above tolerance disclose at Clause 34(b). Three-bucket match per वेंडर.
खंड-wise totals tied directly to Form 3CD Clause 34(a). नहीं re-keying.
क्लाइंट भेजें portal exports piecemeal, Q1 26AS in अप्रैल, Q2 in जुलाई, AIS in सितंबर. CORAA accepts every file as it arrives, merges with the canonical मिलान, supersedes earlier versions automatically. The ऑडिटर never reorganizes a folder of PDFs.
मिलान isn't a tie-out; it's a story. Every row that fails to match carries a cause, missing TAN in books, GSTIN mismatch between books and portal, period misalignment, supplier filing lag, or auditee under-collection. The ऑडिटर sees the reason without investigating from scratch.
