Built-In Tax Calculator for Tax Firms | Taxza

Taxza includes a configurable tax calculator. You manage tax years and slabs for salaried individuals, businesses and AOPs, rental income, pensioners and companies, with live monthly-to-yearly conversion. The same engine is exposed via API, so you can power a public calculator on your own website from the figures you maintain.

The problem

Tax computations done by hand or in ad-hoc spreadsheets are error-prone and go stale as slabs change. And when a firm wants a calculator on its public website, it usually means maintaining the numbers twice.

How Taxza solves it

Taxza centralises the tax years and slabs you use across taxpayer categories and calculates from them consistently. Update the figures once, and both your internal work and the public calculator on your marketing site (via the API) stay in step.

How it works

1

Configure years and slabs

Maintain tax years and slabs for each taxpayer category in one place.

2

Calculate consistently

Compute liabilities with live monthly/yearly conversion for salaried, business, rental, pensioner and company cases.

3

Publish via API

Expose the calculator through the API to run it on your public website from the same numbers.

  3. Your website calls the API to offer the same calculator publicly.
  4. When slabs change, you update once and both stay current.
