DosCifras

DosCifras is a growing suite of free, no-signup tax and finance calculators built specifically for Spanish speakers — not a translated template. It currently covers Spain, Mexico, Argentina, Colombia and Chile across five tools: income tax (IRPF), VAT (IVA), net salary, currency conversion, and investment capital gains. Each country's calculator is researched and verified against its own official tax authority (AEAT, SAT, ARCA, DIAN, SII), because tax rules genuinely differ by country — not just by the numbers. DosCifras is a calculation tool, not tax advice.
