Tax procedures in Andorra: Updated 2026 Guide

If you run a business in the Principality, understanding tax procedures in Andorra is essential to operate with legal certainty and take advantage of the country’s favourable tax environment.

As of 2026, Andorra maintains an attractive tax model, with low tax rates and accessible administrative processes. In addition, several procedures can already be carried out electronically via the official portal of the Andorran Tax Administration (Tributs).

This article, based on official sources, explains which taxes apply, how to file them, and which digital tools are available to businesses and self-employed professionals.

Understanding tax procedures in Andorra

Applicable taxes

Andorra’s tax system is governed by specific laws that establish direct and indirect taxes. The main taxes are:

• Corporate Income Tax (IS) (Law 95/2010): levied at a general rate of 10% on company profits.
• General Indirect Tax (IGI) (Law 5/2014): equivalent to VAT, with a general rate of 4.5%.
• Non-Resident Income Tax (IRNR): applicable to foreign individuals or entities with income sourced in Andorra.
• Personal Income Tax (IRPF): applies to resident individuals, with a maximum rate of 10%. 

There are no taxes on wealth, inheritances or donations.

Available electronic tax filing options

Many tax procedures can now be done online. Tributs provides access to its platform at www.impostos.ad, where you can:

• File IGI returns
• Submit Corporate Income Tax declarations
• Request tax certificates
• View tax deadlines and payment status

Online declaration of the IGI

Filing IGI returns is mandatory via the ATC’s online platform. Companies must file monthly or quarterly, depending on turnover.

Basic steps:

2. Identify yourself using a valid digital certificate

Key tax benefits of the Andorran system

Andorra’s tax framework is among the most competitive in Europe for several reasons:

• Corporate Income Tax capped at 10%, with deductions for new activity or reinvestment
