India’s income tax system saw sweeping changes effective April 1, 2026, under the new Income Tax Act, simplifying compliance for businesses while introducing targeted reforms. These 19 key updates focus on slabs, deductions, filings, and digital tools, helping enterprises optimize taxes amid economic shifts.

New Tax Slabs Structure

The default tax regime now features revised slabs: 0-5% up to Rs 4 lakh, 10% to Rs 8 lakh, 15% to Rs 12 lakh, 20% to Rs 16 lakh, and 30% above, with a Rs 60,000 rebate under Section 87A for incomes up to Rs 12 lakh. Businesses benefit from aligned corporate rates at 25% for turnover under Rs 400 crore, reducing effective burdens.

HRA Exemption Expansion

HRA relief at 50% of basic salary extends to Bengaluru, Pune, Hyderabad, and Ahmedabad, alongside Delhi and Mumbai, easing costs for relocated staff. Employees need rent agreements and receipts, but firms can now claim these seamlessly in payroll deductions.

TDS/TCS Threshold Hikes

TDS thresholds rise to Rs 50,000 for salaries, interest, and professional fees; TCS to Rs 10 lakh for foreign remittances. Businesses handling high-volume transactions save on withholding compliance, with quarterly TCS filings simplified via portals.

ITR Filing Deadlines Extended

ITR-1/ITR-4 due by July 31; others by September 30 for AY 2026-27, with pre-filled forms pulling data from 26AS and AIS. This reduces errors for SMEs filing multiple returns.
Presumptive Taxation Boost

Limits for professionals under Section 44ADA jump to Rs 75 lakh turnover (95% presumptive income); businesses to Rs 3 crore if cash receipts below 5%. Ideal for consultants and startups minimizing audits.

Capital Gains Rationalization

Long-term gains tax fixed at 12.5% without indexation for property/stocks held over 24 months; short-term at slab rates. Businesses selling assets gain predictability in planning.

Section 80C Limit Uplift

Deduction cap rises to Rs 2 lakh, including NPS Tier-2 and skill development spends. Firms can guide employees on maximizing family contributions.

Advance Tax Relaxation

Quarterly payments required only if liability over Rs 10,000; self-assessment tax under Rs 1 lakh waived. Eases cash flow for seasonal businesses.

Digital Compliance Tools

Mandatory e-verification of returns within 30 days; AI audits for high-risk cases flagged via faceless systems. Portals now integrate UPI for instant refunds.

Other Notable Shifts

  • Startup tax holiday extended to March 2030.
  • MAT credit carry-forward to 20 years.
  • Foreign income deemed at resident rates with DTAA relief.
  • Electric vehicle deductions at 200% under 80EEB.
  • Surcharge capped at 25% for incomes over Rs 5 crore.
  • Gift tax exemptions for business transfers.
  • Loss set-off limits eased to 80% of profits.
  • Senior citizen basic exemption to Rs 5 lakh.
  • Crypto gains taxed at 30% flat, no offsets.
