Choosing between old and new tax regime is a high-value decision for salaried professionals. This tool helps you compare both regimes using salary, deductions, and rebate logic so you can choose the regime that minimizes annual tax outflow for your current profile.
For example, with ₹18,00,000 salary and moderate deductions, the comparison can show whether old regime deduction benefits outweigh simplified slab treatment in the new regime. Update deductions to test best and worst-case filing scenarios before declaration deadlines.
Both regimes use slab-wise marginal tax computation. Old regime applies standard deduction plus eligible deduction buckets before slab tax. New regime applies its configured standard deduction and slab rates. Cess and rebate checks are applied after base slab tax to derive final payable tax.
In many cases old regime performs better when eligible deductions are substantial, but exact outcome depends on income and deduction mix.
Yes. The calculator applies cess and basic rebate logic after slab computation for practical planning output.
No. Use this for planning decisions. Final filing values should be validated with official documents and rules.
