From a free tool to your own software

Software for CA firms and payroll tax teams

Tax practitioners and payroll teams run the same regime comparison for every client and employee each year, collecting investment proofs over email and re-entering figures into worksheets. Mistakes surface later as mismatched TDS or a notice. Purpose-built software collects declarations, applies the rules for whichever year you configure and keeps every computation traceable.

  • CA practice management systems

    Track each client's filing status, documents, deadlines and fees across your team, with reminders ahead of due dates and a clear view of pending work.

  • Employee tax declaration portals

    Employees choose their tax regime, declare investments and upload proofs, then see a projected tax figure that payroll uses to set their monthly TDS.

  • Client document collection apps

    Clients upload Form 16, bank statements and capital gains reports from a phone, sorted by assessment year, with a checklist showing what is still missing.

  • AI-assisted document extraction

    Read figures from salary slips, interest certificates and broker statements into your computation worksheet, so preparers review numbers instead of retyping them.

Who we build this for: Chartered accountant firms, tax practitioners, payroll teams and HR departments handling employee TDS.

This tool runs entirely in your browser. The team that built it designs custom software for businesses and runs DigiSign, our own signage platform, in production.

Questions people ask

What are the new regime tax slabs for FY 2026-27?

0–4L: nil, 4–8L: 5%, 8–12L: 10%, 12–16L: 15%, 16–20L: 20%, 20–24L: 25%, above 24L: 30% — plus 4% cess on the tax. These figures are shown here as verified in August 2026; always check the current Finance Act before filing.

Is income up to ₹12.75 lakh really tax-free under the new regime?

Yes, for a salaried taxpayer with no other deductions: the ₹75,000 standard deduction brings a ₹12.75 lakh salary down to ₹12 lakh taxable income, and the ₹60,000 rebate (available up to that exact threshold) wipes the computed tax to zero.

How much tax on a ₹15 lakh salary in the new regime?

About ₹97,500 including cess, after the ₹75,000 standard deduction brings taxable income to ₹14,25,000 — this calculator shows the exact slab-wise split for your own salary figure.

Which regime is better — new or old?

The new regime wins for most salaried people without large deductions, since it has wider slabs and a bigger rebate. The old regime can win if you have substantial 80C investments, a home loan, HRA exemption and 80D insurance stacked together — enter your figures in the deductions panel and let the calculator compare.

What is marginal relief and when does it apply?

Just above the rebate threshold (₹12 lakh taxable in the new regime), the rule caps your tax at the amount your income exceeds ₹12 lakh by — so someone earning ₹12.1 lakh taxable never ends up with less take-home than someone earning exactly ₹12 lakh. This calculator applies it automatically when it kicks in.

Can I switch tax regimes every year?

Salaried taxpayers with no business income can choose their regime afresh each year while filing their return — there is no lock-in. Those with business or professional income face restrictions on switching back to the old regime after opting for the new one.
