India Compliance Calendar FY 2026–27 | Guidance About Compliance Filing:

By Acumen Financial Solutions (AFS)

This compliance calendar is not a generic checklist. It is designed based on real execution experience, including:

• Reconstruction of accounts for ₹100Cr+ companies

• Completion of backlog compliance within strict deadlines

• Implementation of structured accounting, cash flow systems, and reporting

                    

Every date in this calendar has legal, financial, and operational consequences.

CRITICAL UPDATE (Most Firms Are Missing This)

Income Tax Act 2025 (Effective 1 April 2026)

This is where most businesses and even CA firms are currently making mistakes.

Key Changes:

• TDS sections renumbered and restructured

• Some sections split into multiple categories

• Section 194LD removed

• TCS rates revised (e.g., 5–20% → 2% in certain cases)
  
  

Practical Impact:

• Wrong TDS section = incorrect deduction

• Incorrect deduction = penalty + disallowance

• Recurring invoices must be manually updated in many cases

👉 Many businesses think software will handle this.

Reality: Manual expert validation is required.

This is where AFS adds real value.
