Tax Calculators
Tax rules change often, and most confusion comes from not knowing which number a rule applies to. CalPaisa's tax calculators start from your actual figures — salary, invoice value, sale proceeds — and show the tax due along with the working behind it. Compare the old and new income tax regimes on the same income to see which one leaves you with more, split an invoice into base price and GST in either direction, or estimate capital gains on an asset sale. Every result lists the slab-by-slab or component-by-component breakdown, so you can check it against a payslip, a tax notice or your accountant's summary. Use them to plan declarations early in the year rather than discovering a shortfall in March.
