How income tax rates and slabs work

An income tax slab or bracket is a range of taxable income to which a specified rate applies. Under a progressive system, different portions of income may be taxed at different rates; the highest marginal rate is not necessarily the rate paid on all income.

Taxable income generally means income remaining after exclusions and permitted deductions under the law of the relevant jurisdiction. A tax credit usually reduces calculated tax, whereas a deduction generally reduces the income on which tax is computed. A tax resident may be taxed on a different basis from a non-resident, including possible worldwide-income reporting or treaty relief.

When comparing countries, check national and subnational taxes, social insurance contributions, surcharges, filing status, dividend taxation, capital gains, withholding taxes and double taxation agreements. Corporate tax rates are not necessarily the same as personal income tax rates.

For India, consult the Income Tax Department and official tax law resources. The Income-tax Act, 2025 applies from 1 April 2026, subject to transitional provisions for earlier tax periods; always select the law applicable to the relevant tax year.

Frequently asked questions

How do I find the current tax slab for my country?

Choose your country's official tax authority above, select the correct tax year and taxpayer category, and verify the latest published rates and allowances.

Are income tax rates the same for residents and non-residents?

Not always. Residence, source of income and tax treaty provisions can change applicable rates and reporting obligations.

Do capital gains and dividends use the same rates as salary?

Not necessarily. Many jurisdictions impose separate rules or rates on capital gains, dividends, interest and business income.

Can I use a 2018-19 tax article for a 2026 return?

No. Older LawDadi articles are included as an archive. Verify current legislation and official guidance for the applicable tax period.
