The renumbering exercise under the Draft Income Tax Rules, 2026 touches almost every form a payroll or HR team files on an employee's behalf. Here's a practical map of what's changing, and what to check before the new cycle begins.
Why the form numbers are changing
The Income Tax Act, 2025 restructures the framework that has governed direct tax compliance for over six decades. As part of that restructuring, forms tied to employee declarations, salary TDS, and year-end reporting are being renumbered and, in several cases, reorganised to match the new section references.
For payroll teams, the practical impact isn't the new number itself — it's making sure every downstream system, template, and internal checklist points to the right form before the first return of the new cycle falls due.
"A new form number doesn't mean a new tax rule — but it does mean every template you rely on needs a fresh look."
Legacy vs new: a side-by-side view
The table below lines up a few of the most commonly used employee-facing forms against their proposed successors.
| Legacy form | Draft 2026 equivalent | Used for |
|---|---|---|
| Form 12BB | Form 124 | Employee claims statement (HRA, LTC, home loan interest) |
| Form 12B / 12BAA | Form 122 | Particulars of income from a previous employer |
| Form 24Q | Form 138 | Quarterly salary TDS statement |
| Form 10DA | Form 34 | Audit report for additional employee cost deduction |
Employee declaration forms you'll need
Before the new filing window opens, most HR teams find it useful to work through a short internal checklist. Use the one below as a starting point and tick items off as your organisation confirms them.

0 / 6A note on HRA and landlord details
Under the draft rules, the relationship with the landlord becomes a mandatory field alongside PAN and Aadhaar on the employee claims statement. It's a small addition on paper, but it's the kind of field that trips up bulk uploads if it isn't accounted for early.
Deadlines payroll teams should mark
Misreporting a landlord's PAN or Aadhaar — even unintentionally — can attract penalty under Section 270A. Build a validation step into your claims-collection process rather than relying on manual review alone.
What this means for HR and compliance teams
Three things are worth prioritising over the next filing cycle: updating internal templates to the new form numbers, briefing employees on any new mandatory fields, and confirming that your payroll or TDS software has already mapped the legacy-to-new form correspondence.
Teams using an integrated TDS solution typically find this transition easier, since form mapping and validation rules are handled centrally rather than being rebuilt in every spreadsheet.
Key takeaway
Treat this as a mapping exercise, not a compliance overhaul. The obligations are largely unchanged — only the references and a handful of mandatory fields are new.
Key takeaways
- Every employee-facing form used by salary-paying employers is being renumbered under the 2026 draft rules.
- Relationship-with-landlord is a new mandatory field for HRA claims.
- Confirm your payroll and TDS software has updated its form templates before the next filing cycle.
