A chain transaction is a series of successive supplies of the same goods between several businesses, where the goods must be transported directly from the first supplier to the last supplier in the chain. A chain transaction involves a minimum of three companies. Until 2020, there were no VAT rules for chain transactions in Slovakia, and in many other EU Member States, which caused difficulties in determining the mobile supply when the transport of goods was provided by an intermediary. The new chain transaction legislation is part of an EU package of VAT amendments known as Quick Fixes.
