Workbook-style assessment
Monthly salary breakup
Components run vertically and months run horizontally, following the structure of the attached “2026-27 AY” sheet.
Salary grid
Values save automatically. Group rows are informational and do not double-count totals.
Bank interest income
Track Savings separately from FDs & RDs, bank by bank and month by month.
Income-tax declaration
Investment & exemption declaration
Capture common salaried declarations and compare old vs new regime treatment for supported assessment years.
Annual assessment
Tax summary & monthly plan
Compare regimes, see how salary and bank interest flow into taxable income, and review payroll TDS.
Local data controls

Current record

Bundled tax-rule scope
The calculation engine is intentionally narrower than an ITR filing utility.

Not filing-grade
