The Netherlands levies a wealth tax (a.k.a. the box 3 tax) on your assets in lieu of a capital gains tax. Certain American account types are exempt from box 3 taxation. Use this calculator to figure out approximately how much you would owe. This calculator uses the 2023 box 3 rates. Note that the box 3 tax regime is in the process of undergoing an overhaul. In December 2021 the Dutch supreme court ruled that the way returns were being taxed in box 3 violated property rights. In response to the court the Dutch government is working on a replacement box 3 system that is supposed to go into effect starting in 2026. In the interim the government has passed bridging legislation that governs how box 3 taxes will be levied until 2026. PWC has a detailed article on the history of box 3 taxation, that also keeps track of ongoing legislative debates and proposals.
If you have the 30% ruling, you are exempt from box 3 taxation.

Bank Balances
Add up the balances (as of Jan 1st) of all your bank accounts (current or savings) worldwide. Include here money that is not invested in stocks, bonds, cryptocurrencies etc. These assets are assumed to earn a lower 'imaginary return', and are thus subject to less taxation under box 3.

Investments and Other Assets
Add up the balances (as of Jan 1st) of all your investments worldwide. Examples of account types include the balances of investment accounts where you hold stocks, mutual funds, bonds or ETFs, health savings accounts (HSAs), IRAs, cryptocurrency. Visit the belastingdienst site for a complete list of assets that must be disclosed. Notably, your owner-occupied residence is not considerd a box 3 asset. Second homes and rental properties do count as box 3 assets. Read the belastingdienst link for details on how to calculate the value of such properties for the purposes of a box 3 declaration.
Your assets are assumed to yield a return, and you are taxed on this imaginary return.

Total Liabilities
Visit the belastingdienst site for a complete list of liabilites that may be included for box3. Do not include mortgage debt for an owner occupied home here unless it is an interest-only mortgage (*aflossingsvrije-hypotheek*). Note that there is a threshold for liabilities, and only liabilities above the threshold will reduce your box 3 tax burden.
