SaaS providers and digital platforms operating in Andorra often face invoice rejections due to the misapplication of the NRT (Tax Registration Number). A frequent issue involves confusing the resident “F” format with the non-resident “E” format during client onboarding.

Andorra’s tax regulations are defined by a centralized system under the Ministry of Finance. This can lead to confusion when the same NRT structure is adapted for different taxpayer categories. These errors, such as using the wrong prefix in E-Invoicing, frequently result in administrative penalties or blocked IGI (VAT) refunds. This article answers the 10 essential questions about TIN in Andorra, providing clear guidance to support effective compliance. It is especially valuable for residents, expatriates, and cross-border businesses, with platforms like TaxDo offering reliable validation tools amid 2026 digital enhancements for e-filing.
