New Income Tax Act 2025 and Income Tax Rules 2026: What Changes for You

April 1, 2026 came and went like any other day for most people. But if you pay income tax in India, that date changed quite a bit.

Two things happened on the same date. The Income Tax Act, 1961 — patched and amended across 65 years and 819 sections — was replaced by the Income Tax Act, 2025. And the old Income Tax Rules, 1962 went with it, replaced by the Income Tax Rules, 2026. Together, they rewrote how crores of salaried employees, retirees, small business owners, and individual taxpayers file and pay their taxes.

Read this once, properly. By the end you'll have a clear picture of what changed, what didn't, and what you actually need to do.

What Are the Changes, Exactly?

Think of it this way. The Income Tax Act is the law — it says what’s taxable, what’s exempt, what the slabs are. The Rules handle the operational detail: which form to submit, what documents to keep, how allowances get calculated. The new Income Tax Rules, 2026 were issued by the CBDT in March 2026 alongside the new Act. Both came into effect April 1.

The old rules had 511 provisions accumulated over six decades of amendments and patches. New ones: 333. That's a 35 per cent cut. The stated intent is to simplify, reduce duplication, and remove the grey areas that generate disputes. Whether it fully delivers on that will play out over time — but structurally, it's a significant cleanup.

Most taxpayers will at least welcome the intention.

Five Things That Actually Changed from April 1, 2026

Enough overview. Here's what actually changed — and who it affects.

1. 'Tax Year' Replaces 'Previous Year' and 'Assessment Year'

This one sounds small but it genuinely confused people — including some experienced filers, honestly. Under the old system, you earned income in the 'Previous Year' but the tax was levied in the 'Assessment Year.' Two different names for what was effectively the same 12-month period. Ask ten people what Assessment Year 2027-28 means and watch the hesitation.

Under the new Act, both are gone. Just one term: Tax Year. Income earned in Tax Year 2026-27 (April 2026 to March 2027) gets reported and assessed with the same name unlike Assessment Year earlier. Your salary TDS certificate — now Form 130 instead of Form 16 — will say Tax Year 2026-27. Simple.

Should have happened years ago, frankly.

2. Four More Cities Get 50 Per Cent HRA Exemption

If you're renting in Bengaluru, Pune, Hyderabad, or Ahmedabad — this one's for you. These four cities have been moved into the 50 per cent HRA exemption bracket. Earlier they were at 40 per cent. Now they're alongside Delhi, Mumbai, Chennai, and Kolkata. Eight cities total at the higher rate.

Previously at 40 per cent. What does jumping to 50 per cent actually mean in rupees? For someone in Bengaluru with a Rs.60,000 monthly basic paying Rs.35,000 in rent, it adds Rs.60,000 in exempt HRA annually. Keep rent receipts, get your landlord's PAN if rent crosses Rs 1 lakh a year, hold the rental agreement. Old regime only.

3. Meal Vouchers, Gift Cards, and Education Allowances — All Revised Upward

The revised allowance limits under the new rules are genuinely more in line with current costs. Meal vouchers are now tax-free up to Rs 200 per meal (up to 2 meals a day, so Rs 400 per working day), revised from Rs 50 per meal under the old rules — a fourfold increase. Children’s education allowance has jumped from Rs 100 to Rs 3,000 per month per child (for up to 2 children), and hostel allowance from Rs 300 to Rs 9,000 per month per child. 

Gift from employer is tax free up to Rs.15000 which Rs.5000 under old rules. Transport allowance for differently-abled employees has also been revised upward — to Rs 15,000 per month plus DA in metro cities and Rs 8,000 per month plus DA in other cities, up from Rs 3,200 per month. These are meaningful numbers, not cosmetic tweaks — especially for employees structuring salary components under the old regime.

4. New Filing Deadlines — One Extension That Matters

August 31 for ITR-3 and ITR-4 non-audit. October 31 for audit cases. ITR-1 and ITR-2 salaried filers — July 31 as always. Made a mistake after filing? You have until March 31 of next year to correct it. Three months more than before.

Salaried individuals on ITR-1 or ITR-2 — you're still on July 31. Audit cases remain October 31, no change there.

But honestly, the more useful change is this one — the window to file a revised return has been stretched from nine months to twelve months from the end of the Tax Year. Made a mistake in your July filing? You now have until March 31 of next year to correct it. Under the old system, the deadline would have been December 31. Three extra months. Quietly, this is one of the more taxpayer-friendly changes in the whole overhaul.

5. New Form Names — And You Need to Know Them

Every major form has a new number. This matters more than it sounds — your payroll team, bank, and CA are all working off these names now. The ones you’ll actually encounter: Form 16 (salary TDS certificate) is now Form 130. Form 16A (TDS for non-salary income) is now Form 131. 

Form 26AS is now Form 168. Forms 15G and 15H have been merged into one — Form 121. Form 12BB, which salaried employees submit to their employer for HRA, home loan, and 80C (Now Section 123 read with schedule XV) deductions, is now Form 124. Form 60 (no-PAN declaration) is now Form 97.

Old form numbers will create mismatches. Verify with your employer and bank that they've switched over before you file.

Filing Under the New Rules: What the Process Looks Like Now

Done this before? There are still a few things that catch experienced filers off guard this year.

1. Your Tax Year is 2026-27 — April 2026 to March 2027. No separate 'Assessment Year 2027-28' label. One period, one name.
2. Get your updated documents. Form 130 is your new Form 16. Deduction declarations you submitted to your employer on Form 12BB are now Form 124. TDS exemption for FD interest? Ask your bank for Form 121 — the merged version of old 15G and 15H. And Form 168 replaces Form 26AS as your annual tax statement.
3. Made a mistake? You have until March 31, 2028 to file a revised return for Tax Year 2026-27. Previously the window would have closed in December 2027. Three extra months — use them if you need to.

The Bottom Line

April 2026 brought more change to India's tax system than the previous ten years put together. The law is cleaner. There's less paperwork. But the decisions taxpayers now have to make — especially the regime choice — carry more weight.
