After more than six decades, the Income Tax Act 1961 has been replaced. The Income Tax Act 2025, effective from April 1, 2026, brings structural changes to how income is assessed, reported, and taxed in India.
This is not a minor amendment or a budget tweak. It is a complete replacement of the governing statute. Here is what changed and how it affects individuals, salaried employees, freelancers, and small business owners.

The New Tax Year Concept
The most visible change for every taxpayer is the elimination of the Financial Year and Assessment Year terminology.
How It Worked Before
Under the old Act:
- Financial Year (FY) 2025-26: April 1, 2025 to March 31, 2026 (year income was earned)
- Assessment Year (AY) 2026-27: April 1, 2026 to March 31, 2027 (year income was assessed and return was filed)
This two-year reference system caused confusion, especially for first-time taxpayers and small business owners.
How It Works Now
The Income Tax Act 2025 introduces a single "Tax Year" concept:
- Tax Year 2026-27: April 1, 2026 to March 31, 2027
Income earned and assessed within this period falls under one unified reference. Tax returns are filed within the same tax year framework.
For the transitional period (AY 2026-27 filing on FY 2025-26 income), both old and new terminology appear on ITR forms. Going forward, only the Tax Year reference will be used.
Simplified ITR Forms
CBDT has notified new ITR Forms 1 through 7 under the Income Tax Rules 2026. While the form numbers remain the same, the internal structure has been overhauled:
What Changed in the Forms
- Section references updated throughout. Old references like Section 80C, 80D, and 80E are replaced with corresponding sections from the new Act.
- Schedules merged and simplified. Overlapping schedules from the old forms have been consolidated.
- Capital gains reporting reorganized with clearer separation between short-term and long-term gains.
- Pre-filled data integration improved. The e-filing portal now pulls more data from Form 26AS, AIS, and TIS into the forms automatically.
- Tax Year field added to all forms alongside the transitional AY reference.
Which Form to Use
| Taxpayer Type | ITR Form | Key Criteria |
|---|---|---|
| Salaried individual (income up to Rs 50 lakh) | ITR-1 | Salary, one house property, other sources only |
| Individual with capital gains or foreign income | ITR-2 | No business income |
| Business owner (regular books) | ITR-3 | Business/profession income without presumptive taxation |
| Small business (presumptive) | ITR-4 | Turnover up to Rs 3 crore (digital) or Rs 75 lakh (professionals) |
| LLPs, firms, AOPs | ITR-5 | Non-company entities |
| Companies | ITR-6 | Companies not claiming Section 11 exemption |
Stricter HRA Documentation
If you are a salaried employee claiming House Rent Allowance exemption, the new Act tightens documentation requirements:
- Landlord PAN is now mandatory for annual rent exceeding Rs 1,00,000 (previously this was a softer requirement with more leeway)
- Rent receipts must include the landlord's full name, address, and PAN
- Employers are required to verify HRA claims more thoroughly before allowing the deduction in Form 130 (the new TDS certificate replacing Form 16)
If your landlord does not have a PAN, they must apply for one. Alternatively, you can provide the landlord's Aadhaar number with a declaration, but this is subject to scrutiny.
What This Means for You
- Ensure your landlord provides PAN before March 31 of each tax year
- Keep signed rent receipts for every month
- If you pay rent to a family member, the documentation requirements are the same
- Failure to provide landlord PAN may result in the HRA exemption being disallowed during assessment
CBDT Digital Data Capture and Analytics
The Income Tax Act 2025 significantly expands CBDT's ability to collect and analyze taxpayer data:
Annual Information Statement (AIS) Expansion
AIS now captures data from more sources:
- All bank accounts (savings and current) transactions above specified thresholds
- Mutual fund purchases, redemptions, and dividends
- Property purchases and sales (registered and unregistered)
- High-value credit card transactions
- Foreign remittances and travel expenses
- Cryptocurrency and digital asset transactions
Taxpayer Information Summary (TIS)
TIS aggregates AIS data into category-wise summaries with pre-computed tax implications. The new Act makes TIS data more prominent in the pre-filing process.
What This Means
Every significant financial transaction you make is likely to be reported to the Income Tax Department. The gap between what the department knows and what you report in your ITR has narrowed considerably.
Before filing your return, download and review both AIS and TIS from the e-filing portal. If any transaction is incorrect, you can submit feedback on AIS before filing.

New Income Tax Rules 2026
Alongside the Act, CBDT notified comprehensive Income Tax Rules 2026. Key rules affecting taxpayers:
New Form Numbers
Most tax forms have been renumbered. Key changes:
- Form 130 replaces Form 16 (salary TDS certificate)
- Form 121 replaces Form 15G/15H (declaration for no TDS on interest)
- New challan codes for tax payments
- Updated return verification forms (ITR-V)
Revised TDS Provisions
- TDS rates remain largely unchanged, but the section references are new
- New TDS payment codes for FY 2026-27 have been notified
- E-TDS return forms have been updated to align with the new Act
Tax Regime Selection
Both old and new tax regimes continue to be available. The new regime (with lower rates but fewer deductions) is the default. To opt for the old regime, you must explicitly choose it before filing.
For business income earners, the regime choice is locked once selected and cannot be changed without specific conditions.
Comparison: Old Act vs New Act
| Feature | Income Tax Act 1961 | Income Tax Act 2025 |
|---|---|---|
| Year reference | Financial Year + Assessment Year | Unified Tax Year |
| Number of sections | 298 sections | Streamlined (fewer sections) |
| ITR forms | Old section references | New section references |
| TDS certificate | Form 16 | Form 130 |
| HRA landlord PAN | Soft requirement | Mandatory above Rs 1 lakh rent |
| Digital monitoring | Limited | Expanded AIS/TIS integration |
| Default tax regime | Old regime | New regime |
What You Should Do Now
-
Familiarize yourself with the new section numbers, especially if you previously tracked deductions by old section references (80C, 80D, etc.)
-
Download and review your AIS and TIS before filing for AY 2026-27
-
Ensure all HRA documentation includes landlord PAN
-
Decide between old and new tax regime. Run calculations under both before choosing.
-
Update your knowledge of ITR forms. Even if you use the same form number as last year, the internal structure is different.

Frequently Asked Questions
Does the Income Tax Act 2025 change tax rates?
The Act itself does not introduce new tax rates. Tax rates are set by the Finance Act each year. The new Act changes the structural framework: section numbering, compliance requirements, form formats, and administrative procedures.
What is the Tax Year concept?
Tax Year replaces the old Financial Year and Assessment Year split. Tax Year 2026-27 runs from April 1, 2026 to March 31, 2027. Filing happens within the same framework instead of referencing a separate Assessment Year.
Do I need to learn new section numbers?
Yes, if you previously tracked deductions by section number (like 80C for investments or 80D for medical insurance). The new Act has different section numbers for the same provisions. The e-filing portal provides a mapping reference.
Is the old tax regime still available?
Yes. Both old and new tax regimes continue. The new regime (lower rates, fewer deductions) is now the default. You must explicitly opt for the old regime if you prefer it.
When did the Income Tax Act 2025 take effect?
The Income Tax Act 2025 took effect on April 1, 2026. It applies to Tax Year 2026-27 onwards. For returns filed for AY 2026-27 (on FY 2025-26 income), the new forms and procedures apply.
