Free GST Calculator and Tax Tools: Common Questions
A free GST calculator, TDS calculator and salary tools made for small businesses, freelancers, accountants and salaried employees across India.
What does a free GST calculator do?
A free GST calculator adds GST to a base price or removes GST from a GST-inclusive amount. It shows the tax split as CGST and SGST for sales within a state, or IGST for sales between states, so you can prepare invoices and check bills quickly.
How is TDS calculated?
TDS is the payment amount multiplied by the rate for the applicable section. For example, section 194C covers payments to contractors and section 194J covers professional and technical fees. Each section has its own rate and threshold limit, so pick the right section before you calculate.
Is my in-hand salary equal to CTC divided by 12?
No. Your take-home is lower than one-twelfth of your CTC because of deductions such as Provident Fund, professional tax and income tax. Our salary calculator gives a quick estimate after PF. Your actual salary slip may differ based on your salary structure.
Are TaxVista calculators accurate?
