The Compliance Burden on Indian Businesses

Indian businesses face one of the most complex tax compliance regimes in the world. Between GST returns (monthly, quarterly, and annual), TDS returns (quarterly), advance tax payments, and various other filings, a typical SME has 30-50 compliance deadlines per year. Miss one, and penalties start accumulating.

For businesses managing this manually, compliance isn't just a legal obligation — it's a constant source of stress and a significant drain on productive time. Automation can transform compliance from a burden into a background process.

How Automation Ensures Compliance

Automated GST Compliance

  • Real-time data readiness: When all invoices are processed as they arrive (not at month-end), your GSTR-1 and GSTR-3B data is always ready before the deadline.
  • GSTR-2B auto-reconciliation: Mismatches identified immediately, not discovered during filing.
  • ITC tracking: Eligible, ineligible, and provisional ITC tracked automatically.
  • E-invoice compliance: Data formatted for e-invoice generation for businesses above ₹5 crore turnover.
  • Deadline alerts: Automated reminders for every filing deadline.
VS

Automated TDS Compliance

  • Vendor classification: Each vendor is classified by TDS section at the time of master creation.
  • Auto-calculation: TDS calculated on every applicable payment with correct rate and threshold tracking.
  • Lower deduction certificates: Section 197 certificates stored and applied automatically.
  • Threshold monitoring: Annual thresholds tracked per vendor — TDS kicks in automatically when exceeded.
  • Return data preparation: Quarterly TDS return data (24Q, 26Q, 27Q) generated automatically.
  • Form 16A generation: TDS certificates generated for vendors after return filing.

Building a Compliance Calendar

A well-structured compliance calendar is the foundation of automated compliance:

Daily

Invoice processing and data validation (automated)

7th of Each Month

TDS payment for previous month (auto-generated challan)

11th of Each Month

GSTR-1 data finalization

14th of Each Month

Review GSTR-2B and reconcile

20th of Each Month

GSTR-3B filing with payment

Quarterly

TDS return filing, advance tax payment

Annually

GSTR-9 preparation, TDS annual reconciliation

ℹ️

With automation, most of these calendar items happen in the background. Your role shifts from data entry to review and approval.
