Estimate what you're likely to owe in box 3 wealth tax — an estimate, not advice. Enter your assets, no account needed.
This is an estimate, not tax advice
This calculation gives a ballpark figure based on your imported portfolio and your own input. The actual assessment may differ: we do not know your full wealth, your personal circumstances, or the latest changes in the law. The Dutch Tax Administration is always authoritative.
You remain responsible for your own tax return. Check every amount yourself or have an adviser review it. StockQuarters accepts no liability whatsoever for damages, additional assessments or fines arising from the use of this estimator.

Estimate — verify it yourself
Calculated on the deemed (notional) return.
Under From 2028 you would pay the same.
The amount above has to actually be there in 2026. This is what you put aside each month for it.
You owe an estimated nothing over 2026, so there is nothing to set aside.
Every step, using the amounts you entered.

The same 2026 figures, charged under the system that applies today and under the bill now before the upper house.
On the deemed (notional) return.
36% on your actual return, above a tax-free result of €1,800 per person.
35% and a tax-free result of €1,900 per person.
The new system does not change what you pay.
Where things stand: the lower house passed the bill on 12 February 2026. The upper house postponed its vote on 30 June 2026 pending an amending act, tabled on Budget Day 2026 and expected to be debated from January 2027. The intended start date is still 1 January 2028. The mitigations in the third column (rate down to 35 %, tax-free result up to € 1,900) appear as options in the 19 June 2026 letter to parliament — they are not a tabled proposal, let alone law.
Not included: the one-year loss carry-back that is also under consideration. It only bites when a loss year is followed by a profit year, which a single-year calculation cannot see.
The levy leaves your portfolio every year. So you lose more than the tax itself — you also lose everything that money would have earned afterwards.
Of that, €0 is tax paid and €0 is the return you therefore missed out on.
| Year | System | Levy | Portfolio |
|---|---|---|---|
| 2026 | Current | €0 | €0 |
| 2027 | Current | €0 | €0 |
| 2028 | From 2028 | €0 | €0 |
| 2029 | From 2028 | €0 | €0 |
| 2045 | From 2028 | €0 | €0 |
Assumptions: your savings, debts and green holdings stay flat, and the new system starts in 2028. No portfolio returns the same percentage every year — this is a worked example, not a forecast.
The statutory figures for years after 2026 are not published yet. Those years are calculated with the 2026 figures; in reality they are indexed annually.

The current system automatically charges the lower of the first two.
