Form 10E to Form 39: Salary Arrears Relief Transition Guide
Claiming relief on salary arrears is a computation-first exercise. The form is only the final layer; the year-wise working paper underneath it is what the relief actually rests on. With the Income-tax Act, 2025 and Finance Act 2025 changes now in effect, the form numbers have shifted — and using an old form number out of habit, without checking what the department currently requires, is an avoidable mistake.
This guide is intended for Indian taxpayers, salaried employees, and return filers navigating the transition. It is an educational readiness note, not a guarantee of any tax outcome or refund. Match every position you take with the official portal, the notified forms for the relevant period, and your own documents.
What changed
Arrears relief works by spreading the tax liability across the years in which the arrears relate — and that computation requires year-wise details, not just a current-year figure. The form you use to submit that computation must correspond to the applicable law for the period.
| Point | Practical meaning |
|---|---|
| 1 | Salary arrears relief needs year-wise computation. |
| 2 | Form mapping should be checked before claim submission. |
| 3 | Employer records and return disclosure should reconcile. |
Under the Income-tax Act, 1961 framework, the form was Form 10E. Under the new Income-tax Act, 2025 structure, check the official guide to 2025 Act forms to confirm the current prescribed form — Form 39 is the relevant reference for this transition. Do not assume the old label carries forward automatically.
Why it matters now
The current period places two sets of compliance obligations side by side. AY 2026-27 return filing (covering FY 2025-26 income under the Income Tax Act, 1961) and Tax Year 2026-27 compliance (the new framework under the Income-tax Act, 2025) can appear in the same month's to-do list. An arrears receipt in 2026 may straddle both periods.
A clean file for any arrears claim should show: the period the arrears relate to, the law and form applicable, the year-wise income and tax figures used in the computation, the portal form filed, and the supporting employer evidence. Without this structure, the claim is vulnerable — to processing errors, to mismatches with Form 26AS or AIS, and potentially to a notice asking why the relief was claimed without adequate support.
Practical example
An employee who receives salary arrears in 2026 — covering income from one or more earlier years — must obtain an employer breakup showing how much of the arrears relates to each prior year. The computation then recalculates tax for each of those years with and without the arrears, and the relief is the difference. This computation goes into the prescribed form before or alongside the ITR.
Without the employer-provided year-wise breakup, the computation cannot be done correctly. Without the completed and filed form, the relief claim in the ITR has no statutory support and may be disallowed.
Records to keep
- Arrears breakup from the employer, year-wise
- Form 16 for the current year and relevant earlier years if available
- Earlier year income and tax details for the computation
- Completed relief computation worksheet
Step-by-step checklist
- Identify whether the salary arrears relief claim affects AY 2026-27 filing, Tax Year 2026-27 compliance, or both.
- Read the official source and map the prescribed form to your income head, taxpayer category, and period.
- Collect source records, computation notes, challans, statements, and employer declarations before filing.
- Check whether the relief claim changes the ITR form, any schedule, tax payment obligations, or TDS/TCS positions.
- Preserve the final return, acknowledgement, e-verification proof, and the complete computation working papers.

Common mistakes to avoid
- Using Form 10E by habit without checking whether Form 39 applies to the period in question.
- Mixing AY 2026-27 return filing records with Tax Year 2026-27 payment or TDS records.
- Treating a headline slab rate or threshold as a substitute for the actual year-wise computation.
- Filing or submitting the form before reconciling AIS, Form 26AS, challans, employer records, and the ITR.
- Not preserving the official source reference and the computation note alongside the final return.
How MyeCA helps
MyeCA helps taxpayers organise arrears relief records, map the applicable form for the relevant period, compare filing routes, and prepare document checklists. When a CA-led review adds value — particularly for amounts that are significant, for multi-year arrears, or where TDS treatment is unclear — MyeCA helps facilitate that review before the return is filed.
Final checklist
Confirm the period and the applicable law. Read the official source and identify the correct form. Collect the employer breakup and build the year-wise computation. Check the impact on the ITR form and schedules. File the form through the portal, then preserve the acknowledgement, the computation, and all supporting documents together in one folder.
