This English version is a translation provided for convenience. In case of doubt, the Portuguese version prevails: Termos de utilização.
1. Service
Simples IRS offers, free of charge and without registration, calculators and informational content about the tax and social security obligations of self-employed workers in Portugal. Everything is free and there is no paid version. To stay free, the site shows a few discreet Google AdSense ads (see the Privacy policy).
2. Acceptable use
You may use the tools for personal and professional purposes. You may not attempt to disrupt the operation of the site, make bulk automated requests (by software), or copy the content in bulk to republish it as your own.
3. Informational nature
The results are estimates. Read the legal notice.
4. Availability and changes
The site may be changed, suspended or discontinued at any time. These terms may be updated; the date at the top shows the version in force.
5. Applicable law
Portuguese law. In the event of a consumer dispute, you may use an alternative dispute resolution body (list at www.consumidor.gov.pt) or the European online dispute resolution platform.
