Tax guides

Indian tax read through the statute and the rules rather than the headline: what changed, which regime it applies to, and what it is worth in rupees.

How to Calculate Your Gratuity: the Formula Is in the Law, the Ceiling Is Not

The 15/26 divisor is written into the Code on Social Security, 2020. The ₹20 lakh ceiling is not, and still traces to a notification under the Act the Code repealed. The formula worked at real salaries, the rounding rule most calculators get wrong, and when gratuity can be forfeited.

How these guides are written

Primary sources, not summaries

Figures come from the organisation that published them — the regulator, the bank’s own rate card, the filing, the Act. Where a number could not be verified, the guide says so instead of estimating.

The arithmetic is shown

Worked examples are calculated, not illustrated, and every table states the assumptions behind it so you can redo the sum with your own numbers.

Dated, and revisited

Each guide carries the date it was last checked rather than the date it first appeared, and corrections are published on the guide itself.
