DosCifras is a suite of free calculators built on the actual tax rules of each Spanish-speaking country: income tax, VAT, net salary and currency conversion, each citing its official source (AEAT, SAT, SII…). No signup, no fine print — a calculation tool, not tax advice.
Features
- Income tax (IRPF), VAT, net salary and currency calculators
- Localized to each country's own tax authority — AEAT (Spain), SAT (Mexico), SII (Chile) and more
- Official source cited on every tool
- No signup, no ads-wall, instant results
- Currently covers Spain, Mexico, Argentina, Colombia and Chile — and growing
Use Cases
- A freelancer in Spain checking their real net salary after IRPF
- A Mexican small business calculating VAT at the correct regional rate
- Anyone comparing a price with and without tax in seconds
- Converting currency with a live rate, no app to install
Comments
I built DosCifras because the tax calculators I found were either generic — one rate for everyone — or made you sign up for something that should take three seconds. Across the Spanish-speaking world, every country has its own rules: VAT works differently in Mexico than in Chile, and Spain's income tax looks like no one else's. I wanted a tool that respected that: your country's calculator, with your country's official rules, free and friction-free. It currently covers Spain, Mexico, Argentina, Colombia and Chile, and keeps growing.
