I live in the United Kingdom and pay tax in the Netherlands. How will Brexit affect me?
A transition period will be in place until 31 December 2020. During this period, all EU agreements and rules will continue to apply to the UK. Until then, Brexit will not affect the taxes you pay. UK nationals who earn a living in the Netherlands will be treated as EU citizens during the transition period.
After the transition period
After the transition period, the UK will be considered a third (non-EU) country. This means that several tax regulations will cease to apply.
