Understanding Box 3 Wealth Taxation in 2026?
For the 2026 tax year, the Dutch Tax Authority (Belastingdienst) continues to tax wealth using deemed (notional) returns under transitional rules. The deemed return rate is 1.28% for bank savings, 6.00% for other investments/assets, and 2.70% for debts. Savers enjoy a tax-free allowance of €59,357 per person (€118,714 for fiscal partners), and net deemed returns above this limit are taxed at 36%.
The Proposed 2028 Actual Return System?
The proposed 'Wet werkelijk rendement box 3' (Actual Return in Box 3 Act) represents a shift from deemed returns to taxing actual, including unrealized, capital gains and losses at 36%. Under this new regime, the wealth allowance is replaced by a tax-free result of €1,800 per person (€3,600 for partners). While interest, dividends, and rental income are taxed annually, paper capital gains on equities and crypto are taxed as vermogensaanwasbelasting (unrealized gains tax), creating significant debate and ongoing legal adjustments.
