India's Income Tax Law Changed 32 Days Ago. Here Is What Every Business Owner Actually Needs to Know.

The Story :
The Income Tax Act, 1961 was repealed on April 1, 2026. Replaced by the Income Tax Act, 2025. Tax rates unchanged. Section numbers changed. The income tax portal now has two tabs. Wrong tab in July 2026 = defective return.
Sunita runs a trading company in Gurugram. When her CA WhatsApp-forwarded an article in April saying the Income Tax Act 2025 had replaced the 1961 Act, she read the headline, assumed it meant higher taxes, and scrolled past.
It did not mean higher taxes. Her tax rates are exactly the same. Her deductions are the same. Her July 2026 ITR will calculate identically to last year.
But when she opens the income tax portal in July 2026, she will see something she has never seen before: two separate tabs. Tab 1: Income Tax Act 1961. Tab 2: Income Tax Act 2025. If she — or her CA — clicks the wrong tab, her return will be treated as defective.
The new Act is not a tax hike. It is a structural overhaul of how India's income tax system is organised, referenced, and filed. The rates are the same. The traps are new.
The Real Problem — Why This Is Causing Confusion Right Now
For 63 years, every Indian taxpayer, every CA, every company accountant, and every payroll software operated inside the same framework: the Income Tax Act, 1961. Every TDS section number, every form number, every deduction reference, every court citation — all of it pointed back to the 1961 Act.
On April 1, 2026, that Act was repealed and replaced by the Income Tax Act, 2025. The Income Tax Rules, 1962 were simultaneously replaced by the Income Tax Rules, 2026.
Think of it this way: India's income tax system just switched from a 63-year-old manual filled with handwritten amendments in the margins, to a clean new edition that reorganises every chapter and renumbers every page. The content is largely the same. But if you are still citing the old page numbers on a new form — the form gets rejected.
Most business owners are walking into the July 2026 filing season without knowing there was a reprint.
The Law Explained Simply — What Actually Changed and What Did Not
The Income Tax Department's own FAQ confirms: the Income Tax Act, 2025 does not impose any new tax. The intent is to improve readability, ease of understanding, and compliance.
What stayed exactly the same: Tax slabs and rates under both regimes. All major deductions (Section 80C is now Section 123 — same deduction, new number). Five heads of income. New regime remains the default. Rs 12 lakh zero-tax limit continues unchanged.

Practical Impact |
|
819 sections + 65 years of amendments |
536 clean sections across 23 chapters |
Every section reference in software, forms, and notices changes |
|
Previous Year + Assessment Year — two terms |
Single Tax Year (April to March) |
Tax Year 2026-27 = income earned April 2026 to March 2027, filed by July 31, 2027 |
|

3 sections: Sec 392 (salary), Sec 393 (non-salary), Sec 394 (TCS) |
Challans and certificates must reference new numbers for Tax Year 2026-27 |
|
Form 3CA / 3CB / 3CD (audit reports) |
Single Form 26 |
New form applies from Tax Year 2026-27 audit filings |
|
Form 15G / Form 15H (TDS exemption) |
Merged into single Form 121 |
Banks and institutions must update — old forms not valid after April 1, 2026 |
|
Updated return window: 24 months |
Extended to 48 months from end of tax year |
Longer window but penalty rates 25% to 60% depending on delay |
MOST IMPORTANT TRANSITION RULE: Your July 2026 ITR for FY 2025-26 (AY 2026-27) is STILL governed by the Income Tax Act, 1961. Use Tab 1 on the income tax portal. The new Act applies only from Tax Year 2026-27 — your first return under the new Act is in July 2027.
Sunita vs Aman — The Same July 2026 Filing, Two Very Different Results
Aman's CA read about the transition in March. When Aman's July return was prepared: Tab 1 on the portal — Income Tax Act 1961. All section references correct. TDS certificates for FY 2025-26 referencing old numbers — which is correct for pre-April 2026 transactions. Return processed cleanly.
Sunita's accountant defaulted to Tab 2. The portal flagged a mismatch: FY 2025-26 income in a Tax Year 2026-27 form structure. Return returned as defective under Section 139(9) with a 15-day rectification window. Defect rectified after consulting WeConsult India — resubmitted under Tab 1. No penalty. But one additional week of anxiety, additional professional fees, and a refund delayed by six weeks.
The difference is not tax knowledge. It is transition knowledge — knowing which year is governed by which law.
How to Actually Start — 5 Things Every Business Owner Must Do Before July 2026
1. Step 1 — Confirm which portal tab your CA is using for the July 2026 filing — The income tax portal now has two tabs. For FY 2025-26 income (AY 2026-27) — what most businesses will file in July 2026 — your CA must use Tab 1 (Income Tax Act 1961). If your accountant or software has defaulted to Tab 2, the return will be prepared against the wrong legislative framework. Ask this question explicitly before filing begins.
2. Step 2 — Verify that your TDS certificates for FY 2025-26 reference the correct old section numbers — TDS deducted from payments made to you during FY 2025-26 should reference old 1961 Act section numbers (194C, 194J, 192, etc.) because the transactions occurred before April 1, 2026. If a deductor has already updated their software and issued certificates with new section numbers for pre-April 2026 transactions, those certificates may be defective. Raise this with your CA during the Form 26AS reconciliation.
3. Step 3 — Update accounting and payroll software before the first Tax Year 2026-27 TDS filing — From April 1, 2026, all new TDS deductions must be processed under the Income Tax Act, 2025. Salary TDS = Section 392. All non-salary TDS = Section 393. TCS = Section 394. If your payroll or accounting software has not been updated, your Q1 Tax Year 2026-27 TDS challans will cite incorrect sections. The CBDT has confirmed this will cause processing issues. Check your software update status this week.
4. Step 4 — Brief your bank about the new Form 121 for TDS exemption declarations — Form 15G and Form 15H are replaced by single Form 121 under the Income Tax Rules, 2026. If your bank is still issuing Form 15G or Form 15H for transactions after April 1, 2026, the forms are no longer valid. Raise this with your banker if you rely on TDS exemption declarations for business deposits.
5. Step 5 — If you have a pending updated return for FY 2020-21 it is now permanently closed — The window to file an updated return (ITR-U) for FY 2020-21 has permanently closed from April 1, 2026. If you have any pending ITR-U filings for FY 2021-22 or FY 2022-23, file them now — the penalty rates have gone up from April 1, 2026. Rates now range from 25% to 60% additional tax depending on delay.
The Income Tax Act has a new name. The traps for filers are also new. Make sure your July 2026 filing accounts for both.

But Here Is the Other Side…
But here is the other side: the Income Tax Act, 2025 is genuinely a simpler law for most taxpayers, not a more complicated one. The consolidation of 37+ TDS sections into three is a real compliance simplification for businesses dealing with multiple vendor payment types. The single Tax Year concept eliminates the confusion between Previous Year and Assessment Year that has confused first-time filers for decades. The extended 48-month window for updated returns gives taxpayers more time to correct past filings. And the plain-language drafting of the new Act was explicitly designed to be more readable — reducing the dependency on professionals for routine compliance questions over time. The transition disruption is real but temporary. The long-term direction is a simpler system.
One Last Thing — The Law Changed. Your July Filing Has Not.
The Income Tax Act, 2025 went live 32 days ago. But for the return you file in July 2026, nothing changes. Same income. Same deductions. Same portal login. Just — Tab 1. Not Tab 2.
The confusion in the July 2026 filing season will not come from the tax calculations. It will come from accountants, software, and forms that have not been updated for the transition. The best protection is a simple conversation with your CA: which tab, which sections, which forms — for FY 2025-26 versus Tax Year 2026-27.
