India's income tax landscape is undergoing its most significant transformation in over six decades. The New Income Tax Act, 2025 — set to replace the Income Tax Act, 1961 — brings sweeping changes in structure, section numbering, and compliance provisions. With FY 2026-27 already underway, taxpayers, CAs, and businesses must understand these changes to avoid compliance gaps.

This comprehensive guide breaks down all four critical transition areas: TDS section renumbering, TCS section renumbering, income tax form renumbering, and the new capital gain exemption sections — all based on the official New Income Tax Act, 2025 framework.

💡 Key Takeaways
  • The New Income Tax Act, 2025 replaces the Income Tax Act, 1961 with completely renumbered sections effective FY 2026-27
  • Old TDS sections (192–194T) are renumbered under Chapter 393 of the new Act
  • TCS provisions under Section 206C are reorganised under Section 394 of the new Act
  • Capital gain exemption sections like 54, 54B, 54EC, 54F are renumbered to Sections 82–91 in the new Act
  • Income tax forms (ITR-1 to ITR-6) retain their filing logic but are restructured under new schedules
  • TDS rates and thresholds remain largely the same — only section numbers have changed
  • New Section 402 defines "specified persons" liable for TDS — replacing earlier scattered definitions

Why Is the Income Tax Act Being Replaced?

The Income Tax Act, 1961 has been amended over 4,500 times in six decades, making it one of the most complex tax laws globally. The New Income Tax Act, 2025 aims to simplify language, consolidate provisions, remove redundancies, and make compliance easier for common taxpayers. The new Act does not change tax rates in most cases — it simply restructures and renumbers the law for clarity.

The transition affects every person filing taxes — salaried employees, businesses, professionals, and even non-residents. Understanding the section mapping is critical for correctly quoting section numbers in TDS certificates, challans, forms, and legal documents from FY 2026-27 onwards.

1. TDS Section Renumbering Under New IT Act, 2025

All Tax Deducted at Source (TDS) provisions are now consolidated under Chapter 393 of the New Income Tax Act, 2025. The table below maps every old TDS section to its new equivalent for FY 2026-27:

194T393(3)[S.No.7]Payment to partners of firms (interest/remuneration)₹20,00010%10%

Important — Section 402 (Specified Persons): The new Act introduces Section 402, Clause 37 which defines a "specified person" — an individual or HUF whose total sales, gross receipts, or turnover exceeds ₹1 crore (business) or ₹50 lakh (profession) in the preceding FY. Specified persons are liable to deduct TDS where other individuals may not be.

2. TCS Section Renumbering Under New IT Act, 2025

Tax Collected at Source (TCS) provisions previously under Section 206C of the old Act are now reorganised under Section 394 of the New Income Tax Act, 2025. Here is the complete mapping for FY 2026-27:

Old SectionNew Section (IT Act 2025)Nature of CollectionTCS Rate
206C(1) — Alcoholic liquor394(1)(a)Sale of alcoholic liquor for human consumption1%
206C(1) — Timber (forest lease)394(1)(b)Timber obtained under forest lease2.5%
206C(1) — Timber (others)394(1)(c)Timber obtained by any other mode2.5%
206C(1) — Forest produce394(1)(d)Any other forest produce (not timber or tendu leaves)2.5%
206C(1) — Scrap394(1)(e)Scrap1%
206C(1) — Minerals394(1)(f)Minerals — coal, lignite, iron ore1%
206C(1C)394(3)Parking lot, toll plaza, mining/quarrying (lease/licence)2%
206C(1F)394(2)Sale of motor vehicles above ₹10 lakh1%
206C(1G)(a)394(5)(a)Foreign remittance under LRS — education via loan 0.5%; others 5% (threshold ₹7 lakh per year)0.5% / 5%
206C(1G)(b)394(5)(b)Overseas tour package sold by travel agent (up to ₹7L: 5%; above: 20%)5% / 20%
206C(1H)394(4)Sale of goods exceeding ₹50 lakh in a FY — seller with turnover above ₹10 crore0.1%
206C — Luxury goods (new)394(7)Sale of luxury goods above ₹10 lakh (watches, handbags, art, yachts, etc.)1%

Key TCS changes to note:

  • LRS remittances for education (via loan) attract only 0.5% TCS above ₹7 lakh — much lower than the standard 5%
  • Overseas tour package TCS is 20% above ₹7 lakh — very high; plan accordingly
  • New luxury goods TCS (Section 394(7)) is a fresh provision with no old equivalent — applies to watches, handbags, art, antiques, aircraft, yachts, and similar high-value items above ₹10 lakh

3. Income Tax Form Renumbering

The New Income Tax Act, 2025 restructures forms and schedules. While ITR form numbers (ITR-1 through ITR-6) are retained for taxpayer familiarity, the internal schedule numbers, annexures, and section references inside forms have been updated. Here is the complete mapping of commonly used tax forms:

Old Form / SectionNew Form / Section (IT Act 2025)Purpose
Form 16 (under Sec. 203)Form 16 (under Sec. 392 / 396)TDS certificate for salary — issued by employer

ITR-5ITR-5 — new schedule structureFirms, LLPs, AOPs, BOIs
ITR-6ITR-6 — new schedule structureCompanies (except those claiming Sec. 11 exemption)

Critical note: When responding to tax notices, TDS mismatch letters, or filing for FY 2026-27 and later, always quote the new section number. For FY 2025-26 and earlier assessments, continue using old section numbers.

4. Capital Gain Exemption Sections — Old vs New

Capital gain exemption sections are among the most frequently used provisions by individual taxpayers and investors. The New Income Tax Act, 2025 renumbers these under a fresh sequence while keeping all conditions and benefits intact. Here is the complete mapping:

Old SectionNew Section (IT Act 2025)Exemption — Nature and Key Conditions
Section 54Section 82Sale of residential house property: LTCG exemption if proceeds reinvested in 1 residential house property — purchase within 1 year before or 2 years after sale (or constructed within 3 years). Maximum exemption capped at ₹10 crore. Available to individuals and HUFs only.

  3. Train your accounts team: Accounts staff must know both old and new section numbers during the transition period — especially for any notice responses

Frequently Asked Questions

When does the New Income Tax Act, 2025 come into effect?

The New Income Tax Act, 2025 is effective from FY 2026-27 (AY 2027-28). TDS and TCS section renumbering applies to payments made on or after April 1, 2026. For ITR filings for FY 2025-26 (AY 2026-27) and earlier, old section references continue to apply.

No. For returns filed for FY 2025-26 (AY 2026-27), continue using old section numbers — Section 54, 194C, 206C, etc. New section numbers (Section 82, 393, 394) apply from FY 2026-27 returns filed in AY 2027-28 onwards.

Is Section 54 capital gain exemption removed in the new Act?

No, Section 54 is not removed — it is renumbered to Section 82 in the New Income Tax Act, 2025. All conditions remain exactly the same: residential property, 1-year before / 2-year after purchase window, 3-year construction window, and the ₹10 crore maximum cap. The benefit is fully intact.

What is the new section for TDS on salary?

TDS on salary under old Section 192 is now covered under Section 392 of the New Income Tax Act, 2025. The threshold is ₹4,00,000 (aligned with new tax regime basic exemption limit) and tax is deducted at applicable slab rates — exactly as before.

Conclusion

The transition from the Income Tax Act, 1961 to the New Income Tax Act, 2025 is the most comprehensive reform in India's direct tax history.

Yes. Form 26AS under old Section 203AA has been restructured and is now governed by Section 536 of the New Income Tax Act, 2025, referred to as the Annual Tax Statement.

What is the new section number for Section 54EC (capital gain bonds)?

Old Section 54EC — which allows capital gain exemption by investing in NHAI/REC bonds within 6 months — is now Section 86 under the New Income Tax Act, 2025. The exemption limit of ₹50 lakh and 5-year lock-in period remain unchanged.

What are the new TDS rate changes from April 1, 2026?

The good news is that TDS rates have not changed from April 1, 2026. The New Income Tax Act, 2025 has only renumbered the sections — the actual rates, thresholds, and conditions remain the same. For example, TDS on salary is still at slab rates, contractor TDS is still 1%/2%, and professional fee TDS is still 10%/2%. Only the section numbers you quote in challans and returns will change.

Which ITR form should I use for capital gains in FY 2026-27?

For reporting capital gains in FY 2026-27 (AY 2027-28), use ITR-2 (if you have capital gains but no business income) or ITR-3 (if you also have business/profession income). ITR-1 allows reporting of LTCG under new Section 168 (old 112A) up to ₹1.25 lakh only. The form numbers remain the same — internal schedule references use new section numbers.

Is there a Section 54 equivalent in the New Income Tax Act 2025 for first-time homebuyers?

Yes. Old Section 54 — the most commonly used capital gain exemption for residential property — is now Section 82 of the New Income Tax Act, 2025. All benefits are fully preserved: reinvest LTCG in 1 residential house property within 2 years of sale (or 3 years if constructing), maximum exemption of ₹10 crore. First-time homebuyers using capital gains from another property get the same benefit under the new section number.
