Tax
Tax rules change on a published calendar and old rules still apply to old years, so every tool here resolves its constants from a versioned ruleset keyed to the year you select, never to today. The effective date and the primary source are shown on the page, not buried in a footer.
Income Tax
Income Tax CalculatorIncome tax under either regime for the year you select, with the slab breakdown, the 87A rebate, surcharge with marginal relief and cess all shown separately rather than rolled into one figure.Old vs New Tax Regime CalculatorBoth regimes computed on the same income, with the deduction total at which the old regime overtakes the new one. That break-even is the number the choice actually turns on.Advance Tax CalculatorAdvance tax instalments. The percentages are cumulative rather than equal quarters, so the September instalment is thirty percent of the liability, not twenty-five.Section 87A Rebate CalculatorThe section 87A rebate and the cliff at its limit. One rupee of extra income can cost tens of thousands, which is the sharpest edge in Indian personal tax.Surcharge & Marginal Relief CalculatorSurcharge is a percentage of the tax and switches on the moment income crosses a threshold, so without relief a small raise can cost more than it pays. This shows the relief and the cliff it removes.Income Tax Refund EstimatorYour refund, and the interest the tax authority owes you on it if it is late. That interest is routinely overlooked and is taxable when you receive it.Interest u/s 234A 234B 234C CalculatorInterest under sections 234A, 234B and 234C. All three run at one percent a month on part months, so filing one day into a month costs a full month of interest under each applicable section.Marginal vs Effective Tax Rate CalculatorThe two rates that get confused with each other. The marginal rate decides what a raise is worth; the effective rate is what the year actually cost. Under any progressive schedule the second is always lower.Tax on FD Interest CalculatorPost-tax return on a fixed deposit. Interest is taxed at slab on accrual each year, so a 7.25 percent deposit returns about 5 percent to a thirty percent taxpayer, which is below most inflation estimates.Tax on Dividend Income CalculatorTax on dividend income. Dividends are taxed in the shareholder's hands at slab rates in India since the dividend distribution tax was abolished, and only interest on borrowing is deductible, capped at twenty percent.
TDS
TDS CalculatorTax deducted at source on a payment. The rate depends on the section, the nature of the payment and whether the payee gave a PAN, so it is an input rather than a lookup that would go stale.TDS on Salary CalculatorMonthly TDS an employer should deduct from salary. Declaring other income to your employer moves the tax into TDS and avoids advance tax obligations and the interest that follows missing them.TDS on Rent CalculatorTDS on rent, which works differently for individuals and businesses. An individual tenant paying above a monthly threshold has to deduct, which surprises most people renting a home.TDS on Property Sale CalculatorTDS the buyer must deduct on a property purchase. It is computed on the higher of the price and the stamp duty value, and the obligation sits with the buyer, which catches first-time purchasers.TCS on Foreign Remittance CalculatorTax collected at source on foreign remittances under the Liberalised Remittance Scheme. It applies only above an annual threshold aggregated across all remittances, and it is creditable against your income tax rather than an extra cost.
Deductions
Section 80C Deduction OptimizerWhat your section 80C actually saves, and how much of it is wasted above the limit. Provident fund contributions already fill much of the allowance before any voluntary investment is made.Section 80D Deduction CalculatorHealth insurance deduction under section 80D. The two caps are separate rather than shared, and both rise when the person insured is a senior citizen, which is where the largest deductions come from.Section 24(b) Home Loan Interest CalculatorHome loan interest deduction under section 24(b). A self-occupied property caps the deduction; a let-out property allows the whole interest but caps the loss you may set off.
GST
GST CalculatorGST in either direction, with the CGST and SGST split for a supply within a state and IGST for one across state lines. Working backwards from a tax-inclusive price is a division, not a subtraction, and that is where the mistakes are.Reverse GST CalculatorThe pre-tax value inside a GST-inclusive price. Divide by one plus the rate; subtracting the rate from the total is the common error and lands short every time.GST Inclusive vs Exclusive CalculatorBoth readings of the same figure side by side: what the amount comes to if tax is added, and what it contains if tax is already in it. Quoting one and meaning the other is a common and expensive confusion.GST on Under-Construction PropertyGST, stamp duty and registration on a property purchase. GST applies only to under-construction property: once a completion certificate is issued the sale is outside GST entirely, which is a large difference in cost.Input Tax Credit CalculatorNet GST payable after input tax credit. Two things reduce the claim: statutorily blocked credits, and invoices your supplier has not filed, which appear in GSTR-2B or not at all.
Property
Municipal Property Tax CalculatorIndian municipal property tax on the unit area system, which most large corporations now use. The factors for age, usage and occupancy are what make two identical flats pay different amounts.Stamp Duty & Registration CalculatorStamp duty and registration on a property purchase. Both are charged on the higher of the price and the government circle rate, and several states offer a concession to women buyers.
