How can I lower the amount of tax I pay?
It depends on whether you are under the old or new tax regime.
Under the old regime, you can reduce your taxable income by claiming deductions such as:
Up to Rs 1.5 lakh under Section 80C (via investments in PPF, ELSS, LIC premiums, etc.)
An extra Rs 50,000 under Section 80CCD(1B) for contributions to NPS
Premiums for medical insurance under Section 80D
Deductions for donations (80G), education loan interest (80E), and HRA (if you're paying rent)
In the new regime, most of these deductions are not available. But a few benefits still remain, like standard deduction, NPS contributions (by the employer). Additionally, the new regime offers you lower tax slabs as compared to the old regime.
If you don't have too many deductions to claim, the new regime might actually work better, however, you will need to run the numbers.
