FY 2025-26 brought meaningful changes: the new regime's zero-tax threshold effectively covers incomes up to ₹12.75 lakh (after standard deduction), and the slabs were restructured to make the new regime attractive across a wider range. Still, anyone with a home loan and substantial 80C investments may find the old regime worth the paperwork.

The CalcHub Income Tax Calculator India computes your tax under both regimes instantly.

  • Minus deductions: ₹2,75,000
  • Taxable income: ₹9,25,000

  • Plus 4% cess: ₹3,900
  • Tax payable: ₹1,01,400
At ₹12L: New regime wins clearly.

₹18 Lakh Gross Salary

New Regime:
  • Taxable income: ₹18L – ₹75K standard = ₹17,25,000
  • Tax: 5% × ₹4L + 10% × ₹4L + 15% × ₹4L + 20% × ₹1,25,000 = ₹20,000 + ₹40,000 + ₹60,000 + ₹25,000 = ₹1,45,000
  • Plus 4% cess: ₹5,800
  • Tax payable: ₹1,50,800
Old Regime (with ₹4.25L deductions: 80C + 80D + HRA ₹1L + standard ₹50K + NPS):
  • Taxable income: ₹18L – ₹4,25,000 = ₹13,75,000
  • Tax: 5% × ₹2.5L + 20% × ₹5L + 30% × ₹3,75,000 = ₹12,500 + ₹1,00,000 + ₹1,12,500 = ₹2,25,000
  • Plus 4% cess: ₹9,000
  • Tax payable: ₹2,34,000
At ₹18L with ₹4.25L deductions: New regime still wins.

₹25 Lakh Gross Salary

  • Tax: 5% × ₹4L + 10% × ₹4L + 15% × ₹4L + 20% × ₹4L + 25% × ₹4L + 30% × ₹25,000
= ₹20K + ₹40K + ₹60K + ₹80K + ₹1,00,000 + ₹7,500 = ₹3,07,500
  • Plus 4% cess: ₹12,300
  • Tax payable: ₹3,19,800

  • Tax: 5% × ₹2.5L + 20% × ₹5L + 30% × ₹9,25,000 = ₹12,500 + ₹1,00,000 + ₹2,77,500 = ₹3,90,000
  • Plus 4% cess: ₹15,600
  • Tax payable: ₹4,05,600
At ₹25L with ₹5.75L deductions: New regime wins by ₹85,800. Note: Add home loan principal to 80C, and you'd need even more deductions to flip the result.

Surcharge on High Incomes

For incomes above ₹50 lakh, a surcharge applies:

IncomeSurcharge Rate
₹50L – ₹1 crore10%
₹1 crore – ₹2 crore15%
₹2 crore – ₹5 crore25%
Above ₹5 crore37% (old) / 25% (new regime cap)
Under the new regime, surcharge is capped at 25% even above ₹5 crore. This makes the new regime particularly attractive for very high earners.

Why do I owe tax when my employer already deducted TDS?

TDS is an estimate. If you have additional income (bank interest, rent, capital gains, freelance earnings) not reflected in your employer's calculation, or if you chose wrong regime, you owe the difference as self-assessment tax. Always reconcile Form 26AS with your actual income.

How do I report freelance income alongside salary?

Freelance/consulting income falls under "Business and Profession" or "Other Sources" depending on the nature. If you have professional income, you can claim legitimate business expenses. This also affects regime choice — those with business income have limited flexibility to switch regimes.

Is the ₹12 lakh zero-tax applicable to capital gains too?

No. The Section 87A rebate for the new regime applies only to regular income (salary, other sources, business income). Capital gains (STCG/LTCG) are taxed separately at their specific rates even if your total income is below ₹12 lakh. This was clarified by the courts.
