The return, computed from your closed books.
Post entries, close the year, and ITR-3 or ITR-4 is computed from what the ledger already holds.
Start FreeOld regime or new, run on your actual income
The same income, run through both regimes side by side. Not a generic calculator.
| Line item | Old regime | New regime |
|---|---|---|
| Business income, from posted entries | ₹20,000 | ₹20,000 |
| Deductions (80C, 80D, HRA) | Available | Not available |
| Basic exemption limit | ₹3,00,000 | ₹3,00,000 |
| Tax payable | ₹0 | ₹0 |
Illustrative example: a business income of ₹20,000 sits below the exemption limit under both regimes, so the tax is ₹0 either way. The regimes diverge as income grows: the new regime lowers slab rates and drops most deductions, the old regime keeps the deductions.
