Tax Planning Insights

Your effective tax rate (total tax ÷ gross income) is often far lower than your marginal slab. A salaried individual with ₹12 lakh gross under the new FY25 regime pays approximately ₹80,000 - an effective rate of 6.7%, despite the 20% marginal slab. The Income Tax Calculator shows both figures.

Capital gains timing matters: for equity investments just under 12 months, waiting a few more days to cross the LTCG threshold can save the 15% STCG tax on the entire gain. Run both scenarios in the Capital Gains Tax Calculator.

Frequently Asked Questions

Does the GST calculator support reverse calculation?

Yes. The GST Calculator in "remove GST" mode uses: Base Price = GST-inclusive price ÷ (1 + GST rate / 100). Useful when a quoted price includes GST and you need the taxable value for invoicing.

Which income tax regime is better - old or new?

It depends on your deductions. Run both scenarios in the Income Tax Calculator - the old regime benefits those with high 80C investments and HRA; the new regime benefits those with fewer deductions or higher incomes.

What is the capital gains tax rate on equity mutual funds in FY2024-25?

For equity mutual funds: STCG (held less than 12 months) is taxed at 15% + 4% cess. LTCG (held 12+ months) is taxed at 10% + 4% cess on gains exceeding ₹1 lakh per year, with no indexation benefit. See full details in the Capital Gains Tax Calculator.

Which TDS sections does the TDS calculator cover?

The TDS Calculator covers Sections 192 (salary), 194A (interest), 194C (contractor), 194H (commission/brokerage), 194I (rent), 194J (professional fees), and 194DA (life insurance maturity).
