Yes, the Netherlands has wealth tax, also known as "Box 3", and it includes tax on hypothetical yield on your savings accounts. The government got into issues with the European Supreme Court for this: https://home.kpmg/us/en/home/insights/2022/05/tnf-netherlands-box-3-wealth-tax-and-plan-for-future-restoration-of-rights.html https://home.kpmg/us/en/home/insights/2022/05/tnf-netherland... "The box 3 tax rate is assessed against a hypothetical yield. You are not taxed for capital gains or actual rental income. Instead, the Dutch tax office assumes that you enjoy a yield of up to 5.69% over your total asset value, irrespective if any actual gains are higher or lower(!)." Note that actual savings interest rates were close to zero or even negative.
