Reviewed by CA Nikhil Gupta · Last reviewed 23 June 2026
The Income Tax Act, 2025 and Income Tax Rules, 2026 changed virtually every employer-facing compliance form and process. Form 24Q is now Form 138. Form 16 is now Form 130. Form 12BB is now Form 124. Every deadline that employers have followed for decades is now mapped to a new Act. This month-by-month filing calendar gives HR teams and CFOs a complete, verified workflow for Tax Year 2026-27 — covering TDS deposits, quarterly returns, year-end adjustments, and the Form 130 issuance process.

Case Study: GlobalConsult LLP — Building the New Act Compliance Calendar
GlobalConsult LLP's operations head, Deepak, built the firm's first Tax Year 2026-27 compliance calendar in March 2026. Key steps he took:
- Vendor update: Confirmed with payroll software vendor (Greytip) by 25 March 2026 that all TDS sections updated — Section 192 → 392(1), Form 24Q → Form 138 codes, Form 16 → Form 130 templates
- Bank challan codes: Contacted HDFC Bank to confirm new Section 393 payment codes for non-salary TDS were uploaded
- Employee communication: April 1 circular to all 80 employees explaining the new regime declaration process via Form 122 and that their April payslip will show "Section 392(1)" instead of "Section 192"
- Calendar pinned internally: Google Calendar with all deadlines — Form 138 Q1 on 31 July, Form 130 on 15 June 2027, monthly TDS by 7th each month
- Result: Q1 Form 138 filed successfully by 25 July 2026. Zero TRACES mismatches. First employer in their CA's practice to complete Form 138 transition without any revision.
