Choose Your ITR Form
Selecting the correct ITR form is one of the most important steps. Different ITR forms apply to different taxpayers and income situations.
For example:
ITR-1
Generally applicable to eligible resident individuals meeting the conditions for ITR-1, including specified income sources and income limits.
ITR-2
Generally used by individuals/HUFs who are not eligible for ITR-1 and do not have income from business or profession, including certain capital gains and other income situations.
ITR-4
Applicable to eligible resident individuals, HUFs and firms other than LLPs who meet the conditions for presumptive taxation and other specified requirements.
If you are unsure which ITR applies to you, use the applicable ITR selection/help functionality on the Income Tax portal rather than guessing.
Enter Deductions
If applicable, enter eligible deductions and other relevant details.
Depending on the applicable tax regime and circumstances, deductions may include certain investments, insurance, education loans, donations and other eligible items.
Make sure you claim only deductions for which you are actually eligible and have supporting records where required.
Check Tax Regime
For AY 2026–27, the Income Tax Department’s ITR-1 instructions state that the new tax regime is the default tax regime, with an option to opt out and choose the old tax regime where permitted.
Review the tax regime carefully before submitting your return because the available deductions and exemptions can differ between regimes.
What Happens After ITR Filing?
After filing and verification, the Income Tax Department processes the return.
Depending on the result:
- Your return may be processed without additional action.
- You may receive a refund if applicable.
- You may receive an intimation or communication from the department.
- Additional action may be required if clarification or correction is requested.
Keep checking your e-Filing account and registered communication channels for updates.
