The HSM salary requirement changes per year. It is very important that the salaries of your non-EU highly skilled migrants always meet the requirement, even if the employee works parttime. We strongly advise you to keep an eye this as the IND does check this regularly. The fines in case of non-compliance may be considerable. At the beginning of every new year, we announce the salary requirements in a blog. You can also find the new requirements on the IND's website.
