Latvia is a digital frontrunner in the Baltic region, having integrated its tax and business registries into a seamless electronic environment. In 2026, the fiscal landscape is defined by the full implementation of mandatory B2B e-invoicing (linked to the European ViDA initiative) and the expansion of the EDS (Electronic Declaration System). For companies operating in Riga or trading across the EU, navigating the PVN (VAT), Registration Number, and the updated Personal Code (PIN) is the only way to maintain compliance and avoid the automated penalties of the State Revenue Service (VID).

10 Essential Questions About TIN in Latvia
Common Questions
1. What is a TIN in Latvia?
In Latvia, there isn't one single label for a "TIN." Instead, tax identification is tied directly to the entity type:
-
For Businesses: The Registration Number (Reģistrācijas numurs) serves as the primary tax identifier. If the business is registered for VAT, this number is used with the "LV" prefix.
-
For Individuals: The Personal Code (Personas kods) serves as the TIN for income tax and social security purposes.
