About business calculators

Companies and other legal entities pay tax on their profit under official rules and rates: IRC on the taxable income, the reduced SME rate and the derrama. These calculators help you estimate how much a company pays from those rules. They are educational estimates that do not replace accounting or the Modelo 22 return. Each calculator shows the formula it uses, cites its sources and links to the article that goes deeper.
