Numbers with dates, or nothing

itsguido builds interactive calculators for money that crosses borders: hiring, salaries, taxes, rent, returns. It starts with Turkey and expands country by country.

The rule that shapes everything here: a number without a verification date and an official source is a guess, and we do not publish guesses. Every tool shows when its parameters were last verified and links the gazette, bulletin or statistics office they came from. When the law changes, the tools change. That is the product.

The same dataset that powers the tools is open: the parameters endpoint serves every value with its sources, free to reuse with attribution.

Nothing on this site is tax, legal or investment advice. The tools compute what the published rules say, and consequential decisions deserve a professional who knows your case.
