Many of us have only recently heard about new Artificial Intelligence tools to help with conversations and written text. ChatGPT is one of the more prominent AI tools mentioned and how it may be a game changer in the context of student term papers and other written works.  

I wondered how ChatGPT could help me in my professional tax research and writing on mobility tax issues. I thought I would give it a try on the topic of expatriate tax concessions. I posed several questions of the tool to evaluate the quality of the responses. The following thread is an online conversation I had with ChatGPT about European expatriate tax concessions.

My comments are highlighted.


Q: Explain expatriate tax concessions in Europe.

ChatGPT: Expatriate tax concessions in Europe refer to special tax arrangements that are available to individuals who are temporarily residing and working in another country. These tax concessions are designed to provide relief for expatriates and to help alleviate the financial burden of being an expatriate. The exact nature of these concessions can vary from country to country, but some common types of concessions include:

  • Tax exemptions for foreign-source income: Some countries offer tax exemptions on income earned outside the country, up to a certain amount or percentage.
  • Reduced tax rates: Some countries offer reduced tax rates to expatriates, which can help to lower their overall tax liability.
  • Tax credits: Some countries allow expatriates to claim tax credits for expenses incurred as a result of their relocation, such as travel, housing, and language training costs.
  • Tax equalization: Some companies may provide a tax equalization benefit to their employees, which means that they will cover any additional taxes owed as a result of working in a foreign country.

It's important to note that the availability and specific details of expatriate tax concessions in Europe can vary greatly depending on the country, and it's always advisable to seek professional tax advice before accepting a position abroad.

Pat: Not a bad response!


Q: Compare Europe expatriate tax concessions based on available tax research.

ChatGPT: According to tax research, there are a few key factors that can be used to compare Europe's expatriate tax concessions:

  • Cap on exclusions: Some countries, such as the Netherlands, have a cap on the amount of income that can be excluded from taxes, while others, such as France, offer uncapped exclusions.
  • Minimum salary requirements: The minimum salary required to qualify for the tax concession varies greatly between countries. Ireland, for example, has a relatively low minimum salary requirement of EUR 100,000, while Denmark has a higher minimum salary requirement of DKK 844,800. 
    Pat: Okay, ChatGPT wasn’t thinking about salaries in different currencies.
  • Tax rate: The tax rate for expatriates also varies between countries, with some, such as Denmark and Portugal, offering a flat tax rate, while others, such as Spain, have a two-tier system with different rates for different income levels.
  • Eligibility criteria: Different countries have different eligibility criteria for their expatriate tax concessions. For example, Belgium requires proof of a minimum taxable salary of EUR 75,000, while in Greece a 50% credit reduction is available in the calculated tax. 
    Pat: Not really a good comparison of eligibility.
  • Social security contributions: Some countries, such as Belgium, include social security contributions in their expatriate tax concessions, while others do not.
  • Simplicity: Some countries, such as Sweden, offer relatively straightforward expatriate tax concessions, while others, such as Ireland, have more complex programs that may require professional tax advice.

Based on these factors, some of the most beneficial expatriate tax concessions in Europe include:

  • Ireland's Special Assignee Relief Program (SARP), which offers a generous 30% exclusion on wages exceeding EUR 100,000 and is targeted towards higher income inbound executives.
  • France, which offers an uncapped 30% exclusion for qualifying assignees.
  • Belgium's 30% exclusion for qualifying assignees, including social security contributions in the exclusion.
  • The Netherlands' 30% ruling, which has a relatively high cap on the exclusion (EUR 223,000) and a relatively low minimum wage requirement of EUR 41,954.
  • Denmark's flat tax rate of 27% on gross income less social security contributions.

Again, the most beneficial expatriate tax concession will depend on the individual's specific circumstances, financial goals, and income level. It is recommended to seek professional tax advice before accepting a position abroad.

Pat: Unfortunately, the response overlooked a couple of very generous expatriate tax concessions, including Greece’s 50% exclusion and Italy’s 70% exclusion, so the list of ‘most beneficial’ is incomplete.



As with any tax research, how you phrase the ChatGPT query will impact the responses greatly. I found that a small modification to the question can improve the quality of the answers. Perhaps this tool and others can be useful and save us time. But as with many digital assistants, the results still need to be reviewed by a human familiar with the topic to ensure that the answers are appropriate.
