The Income-tax Act, 2025, introduced alongside Finance Act 2025, has changed several form numbers and reference labels that practitioners and taxpayers have used for years. For most compliance purposes, the underlying obligation — matching TDS credit against what deductors have reported — stays the same. What changes is the form name and, in some cases, the schedule or field where the information appears.
This guide is an educational readiness note for Indian taxpayers, founders, and finance teams navigating AY 2026-27 filing alongside Tax Year 2026-27 compliance. It is not a substitute for portal verification or case-specific CA review where amounts are material, residency questions exist, or a notice is involved.
What the transition means in practice
TDS credit is a reconciliation problem. You need to match the deductor's name, TAN, amount on which tax was deducted, tax actually deducted, tax deposited with the government, and the relevant year — before placing a credit figure in the return.
| Point | Practical meaning |
|---|---|
| 1 | Tax credit depends on correct deductor reporting and taxpayer matching. |
| 2 | AIS, Form 26AS, and certificates should be reviewed together. |
| 3 | New form labels should not distract from credit reconciliation. |
The transition risk is not that the underlying law has changed dramatically — it is that a taxpayer or system uses a familiar old form number and misses that the current notified form under the Income-tax Act, 2025 has a different label or structure.
Why the timing creates complexity
AY 2026-27 return filing, Tax Year 2026-27 current-year TDS compliance, pending notices from earlier years, and newly notified forms can all land on the desk in the same month. A clean file for any one of these situations should clearly identify the period involved, the law reference applicable, the portal form being used, whether the action is a payment, a return, or a response, and the supporting documents behind each figure. Keeping these periods separated in your document folders prevents the wrong certificate or challan from ending up in the wrong year's working.
A practical example
Suppose bank interest TDS appears in AIS for FY 2025-26 but is not yet visible in Form 26AS. The right response is to preserve the interest certificate from the bank, raise feedback on the AIS portal if the entry appears incorrect, and wait for the records to reconcile before finalizing the credit claim in the return. Filing ahead of that reconciliation and hoping the mismatch resolves itself creates a credit position that may trigger a demand or delay refund processing.
Records to collect before filing
- AIS
- TIS
- Form 26AS
- TDS certificates (Form 16, Form 16A, or Form 168 as applicable under the notified forms)
- Deductor correspondence or correction confirmations
Resolve a TDS-credit mismatch before claiming it
- Compare the TDS certificate, deductor details, challan, Form 26AS, AIS, and books for the same income.
- Identify whether the mismatch comes from the PAN, period, amount, return filing, or deductor reporting.
- Request the appropriate correction and retain the communication and revised evidence.
- Claim only the credit supported for the relevant year and preserve the reconciliation with the return.

Mistakes that cost time and money
- Using a familiar old form number without verifying whether it is the currently notified form under the Income-tax Act, 2025.
- Mixing AY 2026-27 filing records with Tax Year 2026-27 payment or TDS compliance records.
- Treating a headline slab rate, rebate threshold, or deduction limit as the final computation rather than a starting point.
- Before completing TDS credit transition, reconcile AIS, Form 26AS, challans, books, and certificates.
- Not preserving the official source reference and computation note used for the filing or payment decision.
Where TDS credit transition needs a document-based review
Taxpayers and businesses should organize records for both old and new form regimes, compare filing routes, prepare document checklists, review TDS credit mismatches identified in AIS, and decide when a document-based professional review is worth arranging before submitting a return or responding to a notice.
Before you submit: final check
Confirm the period and year involved, verify the official form number currently notified, collect all supporting records, draft a short computation note explaining how the credit figure was arrived at, confirm the return or payment route is appropriate, and preserve the acknowledgement and e-verification proof in a single folder after submission.
