I Selected Old Regime with My Employer. Can I File ITR Under New Regime and Get Refund?
For many salaried taxpayers without business income, the employer declaration is mainly for TDS estimation. Final tax is computed in the ITR, so you may choose the eligible regime at filing and claim refund if excess TDS was deducted.
If employer TDS was deducted under old regime, this AY 2026-27 guide explains whether salaried taxpayers can choose new regime while filing ITR.
At a Glance
| Point | What it means for you |
|---|---|
| 1 | Employer TDS is not always final regime choice. |
| 2 | Salaried taxpayers often have filing-time flexibility. |
| 3 | Do not mix old deductions with new-regime filing. |
The core question
Your employer collected TDS throughout the year assuming old regime. Now you want to file under the new regime because, after running the numbers, you pay less tax that way. Can you do that?
For most salaried taxpayers who do not have business or profession income, yes — but with important caveats. The employer declaration you submitted in April (or whenever your company asked) was only for payroll TDS estimation. It is not a binding election under the Income Tax Act, 1961. The final regime choice happens in your ITR for AY 2026-27. If the new regime gives you a lower tax, and if you meet the eligibility conditions, the excess TDS deducted under old regime assumptions becomes refundable after you file and e-verify.
The eligibility check matters. If you have business or professional income, the rules are stricter — you may need to use Form 10-IEA and there are restrictions on switching back and forth. For salary-only taxpayers, the switching flexibility is generally wider, but do not assume it is unlimited.
What goes wrong when people get this wrong
The most common error is mixing regimes — claiming old-regime deductions (80C investments, HRA, housing loan interest) while filing under the new regime. The new regime does not allow most of these. Filing a return that claims, say, Section 80C deductions but selects new regime is an inconsistency that either gets rejected by the portal or invites a notice later.
A second error is misreading the employer's Form 16. Your Form 16 shows tax computed under whatever regime your employer used. If you switch regimes at filing time, your taxable income, eligible deductions, and final tax payable will all change. The computation in your ITR must reflect the regime you actually file under — not a copy of the Form 16 figures.
Third: not e-verifying. A refund does not process until the return is e-verified. Many taxpayers file and wait, unaware that the verification step was missed.
Documents to pull together before filing
| Document | Why it matters |
|---|---|
| Deduction proofs | Needed to compare old regime benefit against new regime rates. |
| Employer declaration and Form 16 | Helps reconcile payroll TDS with return-time regime selection. |
| AIS and TIS | Reported income and transaction information to compare with your own records. |
| Form 26AS | TDS, TCS, advance tax, self-assessment tax, refund, and demand details mapped to PAN. |
| Computation working | The bridge between source documents, taxable income, tax paid, and refund or demand. |
| Final ITR acknowledgement | Proof that the return was submitted and later e-verified. |
Do not rely only on the portal's prefilled data. AIS and Form 26AS are useful starting points, but the taxpayer is responsible for the final numbers. If the prefill looks off — say, a TDS credit is missing or an income figure is wrong — investigate before filing, not after.
How to think through the decision
Work through this in three stages.
First, confirm the assessment year. For income earned in FY 2025-26, the return is filed for AY 2026-27. This matters because the Income Tax Act, 1961 framework applies to this return.
Second, run both computations side by side. Under old regime: add up all eligible deductions (80C, 80D, HRA, housing loan, NPS, etc.) and apply the old slab rates. Under new regime: remove those deductions, apply the new slab rates, check whether the standard deduction applies. The regime that produces lower net tax is your answer — but only if you are eligible for that regime.
Third, match TDS to your PAN. Open Form 26AS and check that the TDS your employer deducted is correctly reflected. If there is a mismatch between Form 16 and Form 26AS, resolve it before filing. A refund claim that rests on a TDS credit that the portal does not recognise will be held up.
Pre-filing checklist
- Confirm you are not restricted by business/profession income rules.
- Compute tax under both regimes with final income figures.
- Do not claim old-regime deductions if filing under new regime.
- Match all TDS credits in Form 26AS against Form 16.
- Verify the return preview before final submission — check name, PAN, AY, bank account, regime, ITR form, tax payable, and refund amount.
- E-verify within the allowed timeline after submission.
Choosing the right correction route if something goes wrong
| Situation | What to do |
|---|---|
| Return not filed yet | Reconcile records first, then choose the correct AY 2026-27 ITR form and regime. |
| Portal data and personal records differ | Check the source document, submit AIS feedback where relevant, and note the discrepancy before filing. |
| Return already filed with wrong regime or deductions | Check whether revised return, rectification, or ITR-U is the applicable route — each has different conditions. |
| Large refund, capital gains, business income, or foreign assets involved | CA review before submitting is strongly advisable. |
These correction routes are not interchangeable. A revised return, a rectification request under Section 154, and an updated return under Section 139(8A) solve different problems and have different time limits. Pick the route that matches what the law permits at the time you are acting.
Mistakes that are worth flagging explicitly
Claiming old-regime deductions in a new-regime return is the obvious one. But there are others:
- Not checking Form 10-IEA requirements when business income is involved
- Expecting a refund before e-verifying the return
- Assuming the portal prefill is complete and accurate without cross-checking
- Waiting too long, then finding the revised return window has closed
The return acknowledgement alone is not a complete record. Keep the computation sheet, Form 16, AIS download, deduction proofs, and challans in one folder. If a notice arrives later, the taxpayer who can show the working clearly is in a much better position.
Keeping your evidence file clean
At minimum, the folder should contain Form 16, AIS and TIS downloads, Form 26AS, deduction proofs (if running old regime comparison), the computation note, challans for any advance or self-assessment tax, and the ITR acknowledgement. Name files clearly — for example, "AY-2026-27-Form-16-employer.pdf" or "AY-2026-27-regime-comparison.xlsx". This saves significant time if a CA reviews the file or if the department asks questions.
When a CA review is worth the cost
Get professional review if your return involves a large refund, capital gains, trading income, foreign assets, foreign tax credit, business or profession income, a TDS mismatch, or a notice. Regime switching may seem straightforward but it can interact with Form 10-IEA obligations and other facts in ways that are not immediately obvious. A CA review should produce a clear computation, not just a pre-filled PDF.
MyeCA tools
Use these tools once your source documents are ready. The regime comparator is most useful when you have final income figures. The ITR form selector helps confirm which form to use once all income heads are identified.
Bottom line
Employer TDS is an estimate — not a final regime election. Salaried taxpayers without business income generally retain the flexibility to choose their regime at filing time. The new regime may give you a lower tax bill, and the excess TDS already deducted can come back as a refund. But file the return with a clean computation, keep your regime consistent throughout, and e-verify promptly. If the picture is complicated — multiple income heads, foreign assets, disputed AIS entries — a CA review before submission is the prudent step.
CA Technical Notes
For tax regime topics, the technical review should compare old and new regime using final taxable income, eligible exemptions, deduction evidence, employer TDS, Form 16, business or profession income status, and return-time eligibility. The regime chosen in payroll is not always the final return position, but the return position must be legally available.
For this specific topic, the reviewer should document the working position for "I Selected Old Regime with My Employer. Can I File ITR Under New Regime and Get Refund?" using the taxpayer's facts, the selected AY 2026-27 form, the records used for computation, and the reason each major number appears in the return. The note should explicitly mention whether the issue affects form selection, income classification, deduction eligibility, tax credit matching, refund timing, notice response, or disclosure schedule completion.
The minimum evidence file should include the source statement behind the answer, the calculation sheet, screenshots or downloads from the income tax portal where relevant, and proof for every adjustment. If the position depends on timing, such as AIS updates, Form 16 issue date, revised return deadline, ITR-U restrictions, e-verification, or a notice response window, the date should be written next to the decision. If the position depends on classification, such as capital gains versus business income, resident versus non-resident, old regime versus new regime, or foreign income versus Indian business receipts, the reason for that classification should be recorded before filing.
