Technical and Account Questions
What are heffingskortingen (tax credits)?
Tax credits directly reduce your tax bill euro-for-euro (unlike deductions which reduce taxable income). Main credits are:
– General tax credit (algemene heffingskorting)
– Labour tax credit (arbeidskorting)
Are company phones taxable?
Generally not taxable if deemed necessary for work (doesn’t count toward WKR budget). If not necessary, it’s taxable and must fit within the employer’s WKR discretionary scope.
How do I avoid the tax credit trap with multiple jobs?
Apply loonheffingskorting (combined general and labour credits) only at your highest-paying job. Multiple applications lead to year-end tax bills.
How will false self-employment enforcement change?
More aggressive investigation of ZZP arrangements that resemble employment relationships. Clients face increased compliance risk and may demand stricter contractual terms.

A Burgerservicenummer (BSN) is a unique 8-9 digit personal identifier issued when you register in the Dutch Personal Records Database (BRP). It’s required for all government interactions, including taxes, healthcare, and pensions.
What's the difference between resident and non-resident taxation?
Residents : Taxed on worldwide income across all three boxes, access to all deductions and credits
Non-residents : Taxed only on Dutch-source income, limited access to deductions/credits
What is the Dutch "three-box" system?
The Dutch “three-box” system divides income into three categories for taxation.
Box 1 includes income from work, business, and homeownership.
Box 2 covers income from substantial shareholdings (usually 5% or more in a company).
Box 3 applies to savings and investments (wealth).
Each box has its own tax rules and rates.
What's the "tax credit trap"?
Occurs when individuals with multiple jobs or second earners apply tax credits at multiple employers. Since credits can only be applied once, this leads to under-withholding and unexpected year-end tax bills.
What qualifies as a "substantial interest"?
Owning at least 5% of shares, options, or profit-sharing certificates in a domestic or foreign company, either alone or with a fiscal partner.
