Double Taxation Agreement Uk Spain Brexit

August 18, 2023

The Double Taxation Agreement (DTA) between the United Kingdom and Spain has been a crucial aspect of the economic relationship between these two countries. However, with Brexit, there have been concerns about the impact on the agreement and subsequent potential double taxation. In this article, we will delve into the details of the DTA, the potential changes post-Brexit and how it could affect businesses.

What is the Double Taxation Agreement?

The Double Taxation Agreement is an agreement between two countries that aims to prevent individuals and businesses from paying taxes on the same income twice. In other words, it ensures that taxpayers are not taxed twice on the same income in both countries. The DTA between the UK and Spain was signed in 2013 and has been in force since 2014.

The agreement covers various types of taxes, including income tax, corporation tax, and capital gains tax. It also outlines the conditions under which a taxpayer can claim relief from double taxation. The agreement also establishes the criteria for determining the tax residency of individuals and businesses.

Brexit and the DTA

With the UK`s exit from the EU, there have been concerns about the future of the DTA between the UK and Spain. The agreement was originally signed as an EU member, and the UK`s withdrawal from the EU could potentially lead to changes in the agreement.

However, it is essential to note that the DTA is a bilateral agreement between two countries and is not affected by the UK`s membership in the EU. Therefore, the agreement would still stand even if the UK were to leave the EU without a deal.

However, some changes are likely to occur post-Brexit. For instance, the UK and Spain may need to negotiate a new agreement to address any issues that may arise. This could include changes to tax rates and provisions regarding the residency of taxpayers.

Potential Impact on Businesses

The potential impact of Brexit on the DTA between the UK and Spain could be significant for businesses. The agreement has been vital in facilitating cross-border business activities, and any changes to it could lead to increased costs and administrative burdens on businesses.

For example, if the agreement is modified or revoked, businesses operating in both countries may face double taxation on their income. This could lead to increased costs and reduced profits, particularly for small and medium-sized enterprises.


In conclusion, the Double Taxation Agreement between the UK and Spain has been critical in facilitating cross-border business activities between the two countries. While the potential impact of Brexit on the agreement remains uncertain, it is essential to keep an eye on any developments and prepare for changes. For businesses operating in both countries, it is crucial to seek professional advice to ensure compliance with tax regulations and minimize any potential impact on their operations.
