The Income Tax Act is the law. The Income Tax Rules are the operating manual. While the IT Act 2025 restructured the law itself, the Income Tax Rules 2026 restructure the implementation machinery - forms, procedures, limits, computation methods, and compliance requirements. For most taxpayers, the Rules matter more in daily compliance than the Act itself.
This guide covers the structural simplification (how 511 rules became 333), the substantive changes that affect your tax planning, and the practical actions needed for businesses, salaried employees, and professionals.
The Numbers: Structural Simplification
| Metric | IT Rules 1962 | IT Rules 2026 | Reduction |
|---|---|---|---|
| Total Rules | 511 | 333 | 35% fewer |
| Total Forms | 399 | 190 | 52% fewer |
| Linked to Act | IT Act 1961 (819 sections) | IT Act 2025 (536 sections) | 35% fewer sections |
| Language style | Verbose paragraphs with provisos | Tables, formulas, and structured layouts | Significantly clearer |
| Cross-references | Complex, multi-level | Direct and sequential | Easier navigation |
| Redundant provisions | Many accumulated over 63 years | Removed | Cleaner framework |
How were rules reduced? Three methods: (1) removal of obsolete rules that no longer applied, (2) consolidation of overlapping rules that covered the same subject from different angles, and (3) streamlining of procedural rules into fewer, clearer provisions using tables and formulas instead of narrative text.
Changes That Affect Salaried Employees
HRA Exemption Expanded to 8 Metro Cities
Old Rules: 50% HRA exemption available only in Delhi, Mumbai, Chennai, and Kolkata.
New Rules: 50% HRA exemption now available in 8 cities: Delhi, Mumbai, Chennai, Kolkata, Bengaluru, Pune, Hyderabad, and Ahmedabad. This means taxpayers renting in these 4 newly added cities can claim up to 50% of basic salary as HRA exemption (subject to actual rent paid and conditions).
New requirement: Taxpayers must now disclose their relationship with the landlord. This is to prevent false HRA claims (e.g., paying rent to parents or relatives and claiming tax benefit without genuine rental arrangements). For salaried employees in the newly eligible cities, our income tax return filing services ensure the expanded HRA benefit is correctly claimed.
Allowance and Perquisite Limits Updated
| Benefit | Old Limit (Rules 1962) | New Limit (Rules 2026) | Impact |
|---|---|---|---|
| Children education allowance | Rs 100/month per child (max 2 children) | Rs 1,000/month per child (10x increase) | Meaningful exemption for parents |
| Hostel expenditure allowance | Rs 300/month per child | Rs 3,000/month per child (10x increase) | Aligned with actual hostel costs |
| Meal vouchers (tax-free) | Rs 50 per meal | Rs 200 per meal per day | Reflects current food costs |
| Car perquisite (employer-provided) | Outdated valuation based on cubic capacity | Updated valuation based on vehicle type and usage | More realistic perquisite computation |
| Commuting expense exemption | Limited to employer-provided vehicles | Expanded to employer-reimbursed commuting costs | Broader exemption for transport |
Form 15G and 15H Merged into Form 121
Old system: Two separate forms - Form 15G (for persons below 60) and Form 15H (for senior citizens above 60) - for declaring that total income is below the taxable threshold and requesting nil TDS on interest income.
New system: Both merged into a single Form 121 under Section 393(6). Age-agnostic - one form for all taxpayers. Each Form 121 will now have a 26-character Unique Identification Number (UIN) for digital tracking, reducing the problem of 'missing' declarations during assessments. For accounting and compliance services, the transition from 15G/15H to Form 121 must be communicated to all clients receiving interest income.
Changes That Affect Businesses
TDS/TCS Section References - Immediate Software Update Required
All TDS provisions are now under Section 393 and TCS under Section 394 of IT Act 2025. The Rules 2026 prescribe the new forms, challans, and quarterly return formats referencing these consolidated sections. Every business must update its ERP, payroll, and accounting software to reference the new section numbers from 1 April 2026.
TCS Rates Rationalised to Uniform 2%
| TCS Category | Old Rate | New Rate (Rules 2026) |
|---|---|---|
| Alcoholic liquor for human consumption | 1% | 2% |
| Sale of scrap | 1% | 2% |
| Sale of minerals | 1% | 2% |
| LRS remittance (education/medical) | 5% | 2% |
| Overseas tour packages | 5% up to Rs 10L / 20% above | Flat 2% (no threshold) |
PAN Quoting Requirements Revised (Rule 159)
Rule 159 establishes a comprehensive PAN-based financial tracking ecosystem. Key changes:
- PAN required for motor vehicle purchases - now includes two-wheelers above Rs 5 lakh (previously only four-wheelers above Rs 10 lakh)
- PAN thresholds revised for immovable property transactions and bank deposits
- New Form 97 introduced for persons without PAN entering specified transactions
- Aadhaar-only PAN application route discontinued from 31 March 2026 - proof of DOB now mandatory
Businesses that process high-value transactions must review their PAN collection procedures under Rule 159. For GST and income tax compliance coordination, ensure PAN verification is updated across all systems.
Tax Audit Reports - Same Forms, New Section Reference
Forms 3CA, 3CB, and 3CD (tax audit report and statement of particulars) continue under the new Rules. However, the legal reference changes from Section 44AB (old Act) to Section 63 (IT Act 2025). CAs must ensure audit reports from Tax Year 2026-27 reference the correct section. The reporting structure and content remain substantially the same.
Automated Lower/Nil TDS Certificates
The new Rules introduce a system-based automated process for issuing Lower/Nil TDS certificates. The system evaluates eligibility by pulling data from your past 3 years of filings and current AIS (Form 168). If criteria are met (e.g., projected income below taxable threshold), the certificate can be generated near-instantly - eliminating the manual application process with the AO.
Changes for Investors and Traders
- STT increased: Securities Transaction Tax rates on futures and options have been increased from April 2026 - higher trading costs for F&O traders.
- Buyback taxed as capital gains: Share buyback proceeds now taxed as capital gains (not dividend). Individual promoters face ~30% effective rate; promoter companies ~22%.
- Sovereign Gold Bonds: Capital gains exemption on maturity now limited to bonds purchased during the initial government issue. Secondary market purchases do not qualify for the exemption at maturity.
- Dividend interest deduction removed: Interest expenses incurred to earn dividend income (previously deductible up to 20%) are no longer deductible under the new Rules. Investors with leveraged dividend portfolios will face higher taxable income.
- MAT as final tax: MAT credit accumulation discontinued from April 2026. Existing MAT credits from pre-April 2026 can still be utilised. Rate reduced from 15% to 14%. For investment and tax planning advisory, tax audit services include MAT impact assessment.
Filing and Compliance Changes
| Compliance Item | Old Rules (1962) | New Rules (2026) | Impact |
|---|---|---|---|
| Revised return deadline | 9 months from end of AY | 12 months from end of Tax Year (till 31 March) | 3 extra months to correct errors |
| Revised return fee (late revision) | None | Fee applicable for revisions after 9 months but within 12 months | Cost for delayed corrections |
| Updated return (ITR-U) | Within 24 months of end of AY | Extended further with broader scope | More flexibility for voluntary disclosures |
| ITR filing deadline (non-audit business) | 31 July | 31 August | 1 extra month for ITR-3/ITR-4 filers |
| Form 15G/15H | Two separate forms (age-based) | Single Form 121 (age-agnostic) with UIN | Simpler nil-TDS declaration |
| Lower TDS certificate | Manual application to AO | Automated system-based issuance | Faster processing for eligible taxpayers |
| Digital asset reporting | Limited | Integrated into multiple reporting forms | Broader compliance for crypto/digital assets |
Practical Action Checklist
- 1. Salaried employees in Pune, Bengaluru, Hyderabad, or Ahmedabad: Update your HRA declaration with your employer. You now qualify for 50% HRA exemption. Keep landlord relationship disclosure ready.
- 2. Parents claiming children education/hostel allowance: Update your investment declaration to claim the new Rs 1,000/month (education) and Rs 3,000/month (hostel) limits.
- 3. Businesses: Update ERP/accounting software for Section 393 TDS and Section 394 TCS references. Update PAN collection procedures per Rule 159. Transition Form 15G/15H to Form 121 for interest payments. For payroll management services, all updates are handled proactively.
- 4. CAs and tax professionals: Update tax audit report section references (44AB→63). Download the CBDT rule mapping guide. Update client advisory templates with new form numbers and section references.
- 5. Investors: Review STT impact on F&O trading costs. Evaluate buyback taxation change for portfolio companies. Check Sovereign Gold Bond purchase route for capital gains exemption eligibility.
