The tax works like this: it computes income tax under progressive brackets you can edit, showing marginal rate, effective rate and take-home pay. Everything happens on your device - the input never leaves your tab unless the tool clearly states it performs a server-side lookup.

Frequently asked questions
Are the brackets pre-loaded for my country?
Editable defaults model common progressive systems - replace rates and bands with your jurisdiction's current table for exact results.
What do marginal and effective rate mean?
Marginal is the rate on your top slice of income; effective is total tax divided by total income. Your last earned unit is taxed at the marginal rate - the whole salary is not.
Can I match my country's brackets?
Yes - the bracket table is fully editable, so you enter the thresholds and rates that apply to you and the take-home calculation follows them exactly.
