Compliance & Due Dates

For an Indian CA, CS or tax practice, compliance is the work the firm is actually paid to deliver on time. A single missed GSTR-3B (due the 20th) or a slipped tax-audit 44AB report (30 Sep) can mean late fees and interest for the client and a hard conversation with them afterward. The risk is rarely that anyone forgot a rule — it is that a deadline got buried under a hundred others across a few hundred clients. So compliance, operationally, is a tracking and accountability problem before it is a tax problem.

What “compliance” really covers in a firm

The recurring obligations stack up fast: GSTR-1 on the 11th (13th under QRMP), GSTR-3B on the 20th, the annual GSTR-9/9C by 31 Dec; non-audit ITRs by 31 Jul and audit ITRs by 31 Oct; TDS returns (24Q/26Q/27Q) on 31 Jul, Oct, Jan and May; advance tax on 15 Jun, Sep, Dec and Mar. ROC adds another layer — DIR-3 KYC by 30 Sep, AOC-4 around 30 Oct, MGT-7 around 29 Nov, DPT-3 by 30 Jun. Each obligation has an owner, a status and a dependency on client documents arriving on time.

What to look for in the software

The baseline is a live compliance calendar that maps every client to their applicable returns and auto-generates the next period’s tasks, rather than a static spreadsheet someone updates by hand. Reminders should reach both staff and clients — escalating as a date nears — and the dashboard should show what is pending, filed and overdue at a glance. Statutory artefacts like UDIN and DSC expiry also belong here, since a lapsed certificate can stall a filing.

Most tools on our rankings handle the core calendar; they differ in how proactively they chase clients and how cleanly tasks tie back to billing. Our top-rated pick, QwikCA, pairs an auto-populating GST/TDS/ITR task engine with WhatsApp and email reminders and a UDIN register — though firms with heavy ROC/MCA or statutory-audit needs should check coverage there.
