Diplomatic tax exemption is codified primarily in the Vienna Convention on Diplomatic Relations (VCDR) of 1961. Article 23 exempts the sending state and the head of mission from all national, regional, and municipal dues and taxes on premises of the mission, whether owned or leased, except for charges representing payment for specific services rendered. Article 34 extends personal exemption to diplomatic agents, covering all dues and taxes—personal or real, national, regional, or municipal—with carved-out exceptions including indirect taxes incorporated in the price of goods, taxes on private immovable property held in a personal capacity, estate and inheritance duties, and dues levied for specific services.
For consular officers, parallel but narrower rules appear in the Vienna Convention on Consular Relations (VCCR) of 1963, particularly Articles 32 and 49. Reciprocity is a key operating principle: receiving states typically extend exemptions only to the extent that the sending state grants equivalent treatment to its own diplomats abroad.
In practice, exemptions cover income tax on official salaries, value-added tax (VAT) or sales tax on qualifying purchases (often administered via refund schemes or tax-free purchase cards), import duties on personal effects, and property tax on mission premises. They do not typically cover taxes on private commercial activity, personal investment income from local sources, or charges for utilities and waste collection treated as service fees.
Abuses—such as unpaid congestion charges, parking fines reframed as taxes, or staff misclassification—are recurring diplomatic irritants. Receiving states usually respond through diplomatic notes, ministry-level protests, or, in extreme cases, declaring an individual persona non grata under VCDR Article 9, rather than unilateral tax enforcement, since taxation against immune persons would itself breach the Convention.
Example
In 2021, the UK Foreign Office published figures showing foreign missions in London owed over £116 million in unpaid Congestion Charges, which the missions characterized as a tax exempt under VCDR Article 34.
