Conversor IAE CNAE
conversoriaecnae.es
Free IAE/CNAE code converter for Spanish businesses
The Problem
Spanish businesses need to classify their activities with correct IAE and CNAE codes for tax compliance. There was no official tool to convert between both systems.
The Solution
I built a free converter with semantic search that finds and converts codes in under 200ms, using official BOE data updated quarterly.
