For expats in the Netherlands, wealth building is not just about income, it is about structuring assets intelligently within the Dutch three-box-tax system.

Box 1: Income, Housing, and Retirement Box 1 covers employment income and owner occupied property. Mortgage interest relief can reduce taxable income, while pension contributions and “banksparen” provide tax deferral and long term capital accumulation. If you’re from the United Kingdom, you might recognize them as ISA’s (individual Savings account) and the American equivalent is 401k, and Roth IRA.

This is the foundation for tax free assets and income, boosted with leverage due to cheap residential mortgages.

Box 2: Strategic Use of a BV For expats holding a substantial interest in a Dutch BV, income can be structured between salary and dividends. This creates flexibility and, in many cases, a more efficient overall tax outcome. Retaining profits within the BV also allows for deferred taxation and reinvestment. A BV is also a clever shelter for assets that are usually held and taxed in box 3.

Box 3: Private Wealth and International Assets Box 3 applies to savings, investments, and foreign real estate. Taxation is based on a deemed return rather than actual performance. While foreign assets are included, tax treaties generally prevent double taxation on real estate. That’s an interesting asset that should not be ignored!
