As answered by people managing Codegres.org and Radar Fiscal.
Radar Fiscal's answer:
It's the only tool that shows personalized tax deadlines for Spanish autónomos — filtered by your exact tax regime. Not a generic calendar, not a gestoría trying to sell you services. Just your deadlines, at a glance.
Radar Fiscal's answer:
Competitors are accounting SaaS platforms that happen to have blog articles about deadlines. Radar Fiscal is purpose-built for one thing: knowing what you owe and when. It's free, works as a browser extension, supports 9 languages for expats, and syncs with your calendar app.
Radar Fiscal's answer:
Self-employed workers (autónomos) in Spain, especially expats who aren't yet familiar with the Spanish tax system. Also useful for any autónomo who wants a quick visual overview of upcoming deadlines without navigating the AEAT website.
Radar Fiscal's answer:
I moved to Spain and became autónomo. The AEAT calendar lists every obligation for every taxpayer — overwhelming when you just want to know what applies to you. I built Radar Fiscal to solve my own problem: a simple tool that tells you "here's what YOU need to file, and here's the date."
Radar Fiscal's answer:
TypeScript, Lit (web components), Vite, Cloudflare Workers. Chrome Extension (Manifest V3) and Firefox add-on.
