Calculate your Dutch wealth tax for 2024, 2025 or 2026 under the deemed-return system: separate deemed returns for bank balances, other assets and debts, the debt threshold and the tax-free allowance, and the share by which the return is adjusted — with every intermediate step in the report.
This is a deemed-return calculation: the levy as it follows from the statutory return percentages per asset category, not from your actual return. The counter-evidence scheme and the announced reform fall outside the calculation — they are named in the report as context, but no comparison against an actual return is made and no future scenario is projected. If you want to make that comparison, this deemed figure is the first half of it.
Within that frame the tool follows the official order exactly, sharp edges included. The deemed returns are computed over the full value of your assets while the net base is reduced by deductible debts; with large debts the taxable return can therefore go negative and the levy is set to zero. Just above the allowance the outcome can read “tax due” while the amount lands on € 0. The report shows every intermediate step with tool version and dataset vintage, so such outcomes are traceable.
