DosCifras

About

DosCifras is a suite of free financial calculators for the Spanish-speaking world — built on the actual tax rules of each individual country, not one generic rate applied everywhere. Most tax calculators either force a signup for something that should take three seconds, or treat "Spanish-speaking" as a single market. But VAT works differently in Mexico than in Chile, and Spain's income tax looks like no one else's. DosCifras respects that: pick your country, and get your country's calculator, based on your country's official tax authority — AEAT in Spain, SAT in Mexico, SII in Chile, and more. It covers income tax, VAT, net salary, currency conversion and investment capital gains, across Spain, Mexico, Argentina, Colombia and Chile, with no signup and no fine print. A calculation tool, not tax advice — free, fast, and made for the 400M+ Spanish speakers most tools overlook.

• How Investment Gains Are Actually Taxed in 5 Spanish-Speaking Countries (They're All Different)

  Selling stocks, ETFs or funds in Spain, Mexico, Argentina, Colombia or Chile?

This guide breaks down how each country actually taxes investment gains, based on official tax authority sources, with free calculators for each.
