Netherlands · 2026 · built for expats
Estimate your Dutch wealth tax in under a minute — including the actual-return check most calculators skip, and your foreign assets, which count too.
Use values as they stood on 1 January. Your own home (Box 1) is not included.
Dutch and foreign accounts, savings, cash above €672. Foreign balances count.
Shares, ETFs, bonds, crypto, and a second or rented-out property in the Netherlands. Foreign savings and shares go here too — they're taxed in full. (Property abroad has its own field below.) Not your main home.
Include these in the figure above first — then note how much of it is certified green. The green part is exempt up to the cap, so it's subtracted back out.
A home or rental property outside the Netherlands. Enter its value — it's still reported in Box 3 and counts in the figure below.
This number is the tax before double-tax relief. Most Dutch tax treaties then relieve much or all of the Dutch tax on property abroad — but how much depends on the country, it's reduced if there's a mortgage on it, and you must claim it on your return (it isn't automatic). Confirm your relief with belastingdienst.nl or an adviser.
Personal loans, investment debt, mortgage on a second/foreign property. Not your main-home mortgage.

The standard method assumes a fixed return. If your actual return was lower, you can ask to be taxed on the real figure instead (the tegenbewijsregeling / actual-return rule). Enter your real 2026 return to check.
Interest + dividends + rent + realised and unrealised gains, minus costs, across all the assets above.
We'll email your figures from Guilder Guide, plus a one-line heads-up when the 2027 rates are set so you can re-check — no spam, unsubscribe anytime.

This calculator is for education and general information only — it is not tax advice. It shows the Box 3 tax before double-tax relief on property abroad (which depends on the relevant treaty and must be claimed), and it does not account for every personal circumstance — for example, partial allocation between fiscal partners, or the precise official rules for calculating actual return. Figures are estimates. For your filing, confirm against belastingdienst.nl or a registered Dutch tax adviser (belastingadviseur).
