The calculation of your Box 3 income 2022
This is how you calculate your 2022 Box 3 income:
 Use the abovementioned provisional 2022 rates of return to calculate the return per asset type on 1 January.
 Add the return on bank balances, savings and cash to the return on investments and other assets. You reduce the total by the return on deductible debts. This is your taxable return.
 In addition, you calculate your assets. These are made up of the total of the asset types you have. That is, your assets minus your debts. As for the debts, you first reduce them by the threshold. This is your capital yield tax base.
 You reduce your assets by the taxfree allowance. You now have the basis for savings and investments. You may divide the basis if you have a tax partner.
 You divide your basis for savings and investments by the capital yield tax base and multiply it by 100. Round off to 2 decimal points. This percentage is your share of the capital yield tax base.
 You multiply your taxable return by this percentage. The result is your Box 3 income.
You will pay 31% tax on your Box 3 income in 2022.
