Advance Tax for Tax Year 2026-27 Under the New Act: Checklist
A practical advance-tax checklist for Tax Year 2026-27 covering estimates, due dates, challans, business income, capital gains, and record keeping.
This guide is written for Indian taxpayers, founders, finance teams, and return filers adjusting to the Income-tax Act, 2025 and Finance Act 2025 changes. It is an educational readiness note, not a promise of tax outcome, refund speed, or notice avoidance. Always match the position with the official portal, notified forms, and the taxpayer's own documents.
What changed
Advance tax is forward-looking. It should use current-year estimates and be revised when salary, business profit, rent, interest, capital gains, or TDS assumptions change.
| Point | Practical meaning |
|---|---|
| 1 | Advance tax should be estimated for Tax Year 2026-27 income. |
| 2 | Salary, business income, interest, rent, and capital gains need separate assumptions. |
| 3 | Challan proof and computation notes should be preserved after each installment. |
Why it matters now
The transition creates a year-selection problem. AY 2026-27 return work, Tax Year 2026-27 current compliance, old notices, and new forms can appear together in the same month. A clean file should show the period, law reference, portal form, payment or return type, and supporting evidence.
Practical example
A consultant with uneven receipts in Tax Year 2026-27 should update the estimate each quarter instead of using last year's return blindly.
Records to keep
- Quarterly income estimate
- TDS/TCS expected credit
- Advance tax challans
