Switzerland and Hungary signed a protocol of amendment to the agreement for the avoidance of double taxation with respect to taxes on income and capital (DTA) on 12 July 2024 at Budapest. It implements the minimum standards for double taxation agreements.

The protocol of amendment contains an anti-abuse clause, this is intended to prevent a person who is resident in neither Switzerland nor Hungary from claiming the benefits provided for in the DTA.

The amendment will have to be approved by the parliament of both nations before it can come into force.

The existing Income and Capital Tax Treaty between Hungary and Switzerland was signed on 12 September 2013, replacing the Hungary–Switzerland Income and Capital Tax Treaty of 1981.
