What is Income Tax?
Income tax is a direct tax imposed by the Government of India on the income earned by individuals and certain other taxpayers. The amount of tax payable depends on factors such as your taxable income, applicable tax slabs, deductions, exemptions, and the tax regime you choose.
Old Tax Regime vs New Tax Regime
India currently offers two tax regimes. The Old Tax Regime allows taxpayers to claim several deductions and exemptions, while the New Tax Regime generally offers lower tax rates but allows fewer deductions. The better option depends on your income, investments, and eligible tax benefits.
| Old Tax Regime | New Tax Regime |
|---|---|
| Allows deductions and exemptions. | Lower tax rates with fewer deductions. |
| Suitable for taxpayers claiming significant deductions. | Suitable for taxpayers with fewer deductions. |
Why Compare Both Regimes?
Choosing the right tax regime can reduce your tax liability and improve financial planning. This calculator compares both regimes side by side, making it easier to identify which option may be more beneficial based on the information you enter.
How is Income Tax Calculated?
Income tax is calculated by determining your taxable income after applying the eligible deductions and exemptions available under the chosen tax regime. The applicable tax rates are then applied according to the income tax slabs, and Health & Education Cess is added to arrive at the final tax liability.
Under the Old Tax Regime, eligible deductions such as Section 80C, Section 80D, HRA exemption, and certain other benefits may reduce your taxable income. Under the New Tax Regime, most deductions are not available, but lower tax rates generally apply.
Understanding Common Tax Deductions
| Deduction | Purpose |
|---|---|
| Section 80C | Investments such as PPF, EPF, ELSS, LIC premiums, and certain other eligible investments. |
| Section 80D | Medical insurance premium paid for yourself and eligible family members. |
| HRA Exemption | Available to eligible salaried employees living in rented accommodation, subject to applicable rules. |
| Other Deductions | Eligible deductions under various sections of the Income Tax Act, depending on individual circumstances. |
