Help with your
actual return statement (box 3)
Did you pay box 3 tax for 2021 up to and including 2024 on an assumed return that was higher than what your savings and investments really earned? Then you may report your actual return to the Dutch tax authority (Belastingdienst) with the form "Opgaaf werkelijk rendement", even without a letter and without filing an objection. We collect the figures, calculate your actual return and submit the form for you. You can also do it yourself for free.
* No cure, no pay: you only pay if the tax authority lowers your box 3 tax. How the fee works.
Box 3 for 2021–2024: where things stand
Box 3 is the tax on your assets: savings, investments and, for example, a second home. For years the tax authority used an assumed return, often higher than what savers actually received.
For 2021 up to and including 2024 you may now always report your actual return, with the form Opgaaf werkelijk rendement. You do not need to file an objection and you do not need a letter from the tax authority. The tax authority then uses whichever amount is most favourable for you.
You only file an objection against a final assessment, within 6 weeks of the date on that assessment. So a pro forma objection only makes sense while that period is still running.
When does reporting your actual return pay off?
It depends on what your assets really earned each year. These are the situations where the chance is greatest.
Mainly savings
Was your money mainly in a savings account? Multiply your savings on 1 January by that year's assumed percentage and compare the result with the interest you received. If the interest was lower, reporting pays off.
Investments with a low return
Did your investments earn little in a year, or fall in value? Then your actual return may be lower than the assumed one. If it was negative, the tax authority sets it at €0.
Per year, 2021 up to and including 2024
You fill in a separate form for each year. We calculate per year whether it yields something. From 2025 there is no separate form: you report the actual return in your tax return.
Objections only within 6 weeks
Did you just receive a final assessment you disagree with? Then you can object within 6 weeks of the date on the assessment. We check whether that is necessary in your case.
What does it cost?
The check is free. After that: no cure, no pay.
No cure, no pay. You pay 15% of the box 3 tax you get back or no longer have to pay, with a maximum of €500 for all years together. You only pay if the tax authority lowers your box 3 tax, and only after that decision; if you get money back, only once it is in your account. If it yields nothing, you pay nothing.

Questions about box 3 and the actual return
Not for 2021 up to and including 2024. For those years you may always fill in the form Opgaaf werkelijk rendement, even if you did not receive a letter from the tax authority. You only object against a final assessment you disagree with, within 6 weeks of the date on the assessment.
That ruling concerns 2017 up to and including 2020, and people who did not object at the time, or not in time. According to the Supreme Court (Hoge Raad) they are not entitled to box 3 redress. The ruling does not concern 2021 up to and including 2024.
Anyone who had box 3 income in 2021 up to and including 2024 may fill in the form. Whether it yields something depends on your actual return per year. We check it for you free of charge.
