Important notes
- Netherlands Box 3: Tax is levied on a deemed/fictional return of 6.00% on assets above the €59,357 exemption, taxed at a flat 36% rate. Actual investment gains are not directly taxed.
- The deemed return rate is updated annually by the Dutch government and may change. A legal challenge (Hoge Raad ruling) may result in future changes to Box 3 taxation.
- This projection assumes a constant annual return and does not account for inflation, fees, or market volatility.
