# Income Tax Estimator

Estimates income tax payable under the FY 2024-25 slab rates for the old
or new regime, including the standard deduction, Section 87A rebate, and
4% health & education cess. This is a simplified estimate that excludes
surcharge and itemized deductions like 80C/80D.

## Arguments

Pass an `input` object with:

- `annual_income` (number, required) — gross annual income in INR.
- `regime` (string, optional) — either `"old"` or `"new"` (FY 2024-25 slabs). Defaults to `"new"`.

## Example

```
echo '{"annual_income": 1200000, "regime": "new"}' | python script.py
```
