❓ Frequently Asked Questions — Old vs New Tax Regime
Which tax regime is better — old or new for FY 2024-25?
New regime is generally better for those with limited deductions. At ₹10L income: new regime tax is ₹nil (87A rebate) vs old regime ₹nil (with good deductions). At ₹15L: new regime = ₹1,04,000 vs old regime depends on deductions — old wins only if deductions exceed ~₹3.75L. The calculator gives you exact numbers for your specific case.
What are the new tax regime slabs for FY 2024-25?
New regime slabs FY 2024-25: Up to ₹4L = 0%. ₹4–8L = 5%. ₹8–12L = 10%. ₹12–16L = 15%. ₹16–20L = 20%. ₹20–24L = 25%. Above ₹24L = 30%. Standard deduction: ₹75,000 for salaried. Rebate u/s 87A: nil tax if taxable income ≤ ₹12L. Plus 4% Health and Education Cess.
Can I switch tax regime every year?
Salaried employees can switch regime every year when filing ITR. You can even choose differently from what you told your employer — just file ITR under the preferred regime. Business owners/professionals can switch from new to old only once. After switching to old, they can never go back to new regime.
What deductions are not allowed in new tax regime?
Deductions not available in new regime: HRA exemption (Section 10(13A)), LTA, 80C, 80D, 80E, 80G, home loan interest (Section 24), professional tax. Available in new regime: standard deduction ₹75K (from FY 2024-25), NPS employer contribution 80CCD(2), gratuity and leave encashment exemptions.
What is the default tax regime for FY 2024-25?
The new tax regime is the default from FY 2024-25 (AY 2025-26). If you do not specify a regime to your employer, TDS will be deducted as per new regime. To opt for old regime, submit a declaration (Form 10-IEA for business income) to your employer at the start of the year or select it when filing ITR.
At what income level is new regime always better?
New regime is always better for income up to ₹7.75L (after ₹75K standard deduction, taxable income ≤ ₹7L where new regime 87A rebate makes tax nil). For higher incomes, it depends on your deductions. As a rule: if total deductions (80C + HRA + HL interest + NPS) exceed the "breakeven" amount for your income, old regime saves more.
