What Has Changed & Why It Matters
The Income-tax Act, 1961 was repealed as of April 1, 2026, and replaced by the Income-tax Act, 2025. Key intent: simplify structure, reduce number of forms and rules. New “tax year” concept replaces “previous year/assessment year” model. Reductions in number of forms and rules reflect government’s commitment to easier compliance. (incometax.gov.in)
Choosing Old vs New Tax Regime
Even under the new Act, taxpayers can opt between regimes: the new regime is default, but those who benefit from deductions or exemptions may choose the old regime. Opt-out must be done via ITR on or before due date. (incometax.gov.in)
Example:
Priya, a salaried individual with significant interest income, home loan interest, and deductions under sections 80C/80D, may find old tax regime better; whereas Raj, freelance contractor with minimal deductions, may prefer simpler new regime.
New Requirements & Disclosures
- Foreign Assets of Small Taxpayers Disclosure Scheme (FADS), 2026 allows disclosure of certain undisclosed foreign income/assets as a one-time opportunity. (incometax.gov.in)
- New forms and new rules (Income-tax Rules, 2026) are effective from April 1, 2026, including updated ITR-3 etc. (incometax.gov.in)
- Existing PAN/TAN remain valid; new forms apply only for new applications post-April 1. (incometax.gov.in)
Compliance Strategy
- Compute tax liability under both regimes before filing.
- Retain documents enabling deduction claims (e.g. investments under old regime), even if temporarily under new.
- Use checklist for filing: eligibility, correct ITR form, new challans. (incometax.gov.in)
Common Mistakes to Avoid
- Assuming old deductions cannot be claimed if you fall out of old regime eligibility.
- Missing deadlines or using incorrect forms statutorily substituted under Rules 2026. For instance, ITR-3 updated under Fourth Amendment Rules, 2026. (incometax.gov.in)
- Failing to disclose foreign assets or income that exceed scheme thresholds.
Action Plan
- By end of tax year, list all income sources, debts, investments.
- Estimate tax under both regimes to decide which regime to pick.
- If needed, prepare to use FADS 2026.
- File ITR by due date; use new forms and new payment challans correctly.
