A Netherlands dividend tax calculator that shows what you actually keep after the 15% dividendbelasting is withheld at source, and how the dividend is finally taxed depending on whether you are an ordinary Box 3 investor or a substantial shareholder taxed in Box 2.
How it works
First the withholding is taken at source:
withholding = grossDividend * (whtRate / 100)
afterWHT = grossDividend - withholding
Then the final treatment depends on your shareholder type:
Box 3 (under 5%): the 15% is an advance credited against income tax;
the dividend is not separately taxed, so net ≈ grossDividend
once the credit is settled.
Box 2 (5%+): finalTax = progressive Box 2 rate on the gross dividend;
net = grossDividend - finalTax (withholding is credited).
The Box 2 rate is applied progressively: a lower band on the first slice and a higher band above it.
Example and notes
A 10,000 EUR gross dividend has 1,500 EUR withheld at 15%. An ordinary Box 3 investor sees the 1,500 EUR credited back at assessment, while a substantial shareholder pays the progressive Box 2 rate on the full 10,000 EUR, with the 1,500 EUR already withheld counted toward it.
This ignores the precise Box 2 bracket thresholds and the Box 3 deemed-return interaction. All figures are computed locally in your browser and are not tax advice.
