Immigrants get a 30% tax break, meaning that they only have to pay income taxes over 70% of their income. For the average income of people working at ASML, I guess that they have to pay about 30% taxes. It basically means that ASML can pay less to immigrants workers compared to native workers to give them the same salary.

In the Netherlands we are currently having a housing crisis, which is partly caused by labor immigration. This has caused many people, especially those from gen Z, being unable to buy a house. In and around Veldhoven, where ASML has its main offices, house prices have gone up. ASML is investing some money in housing projects.

For these reasons, some political parties feel that the tax break should be removed. Which would mean that ASML would have to pay their employees more and due to this they will make less profits.

ASML is depending on many companies in and around Veldhoven/Eindhoven and even on some further away for parts of their machines. For that reason, I think it would not be that easy for them to relocate to a different country. They would have to build up contact with local parts produces. If the move to a different country, it maybe also would mean that a part of their employees is not willing to relocate.
