Advanced❓ Frequently Asked Questions — Tax Calculators
Which income tax calculator is best for FY 2025-26?
For FY 2025-26, use the Old vs New Tax Regime Calculator to compare both regimes side-by-side. The new regime is default with seven slabs (5%–30%) and zero tax up to ₹12 lakh (Budget 2025). The old regime is better if your deductions (80C, HRA, home loan interest) exceed approximately ₹4–5 lakh. The Income Tax Calculator on CalcWise covers both regimes for salaried, freelance, and business income.
How do I calculate GST on a product price?
To add GST: Sale price = Base price × (1 + GST rate/100). For example, ₹1,000 base price + 18% GST = ₹1,180. To remove GST from an inclusive price (reverse GST): Base price = Inclusive price / (1 + GST rate/100) = ₹1,180 / 1.18 = ₹1,000. Use the CalcWise GST Calculator for instant add, remove, and reverse-GST computation across all four GST tiers.
What is the advance tax due date for FY 2025-26?
Advance tax for FY 2025-26 is due in four instalments: 15% by June 15, 2025; 45% by September 15, 2025; 75% by December 15, 2025; 100% by March 15, 2026. Freelancers opting for Section 44ADA (presumptive taxation) can pay the entire advance tax in a single March 15 instalment.
How is capital gains tax calculated in India for FY 2025-26?
For equity: STCG (held < 12 months) taxed at 20% flat; LTCG (held ≥ 12 months) taxed at 12.5% on gains above ₹1.25 lakh/year (Budget 2024). For property: LTCG at 12.5% without indexation (new default) or 20% with indexation for properties acquired before 23 July 2024. Use the Capital Gains Tax Calculator for your specific asset type and acquisition date.
