How is my box 3 income calculated on my provisional assessment 2024?
The box 3 income in your provisional assessment 2024 is calculated according to the new legislation. This means we use the actual distribution of your assets. In the calculation, we use fictitious rates of return that are close to the actual rates of return. See what percentages these are and how the calculation works.
Rates of return 2024
In the provisional assessment for 2024, we use fictitious rates of return that are close to the actual rates of return for your box 3 income. That is why we use 2 different rates for your assets: one for your bank balances, and another for your investments and other assets. We use a 3rd rate for your debts.
These are the rates of return for 2024:
- Bank balances: 1.03%
This only includes the following assets:
- bank and savings balances in the Netherlands
- bank and savings balances outside the Netherlands
- cash in excess of the exemption
- premium deposits
- the non-exempt part of your green savings
- your share in the assets of an owners' association (VvE)
- an amount of money that you have transferred to the trust account of a civil-law notary
- Investments and other assets: 6.04%
This includes investments and all other assets that do not fall under bank balances. This concerns, for example:
- shares, bonds, securities and other investments
- the non-exempt part of your green investments
- other receivables (except receivables between tax partners or between parents and minor children)
- a 2nd home in the Netherlands
- a 2nd home outside the Netherlands
- a home that you rent out
- other immovable property
- cryptocurrency
- a ticket on which a prize has fallen
- Debts: 2.47%
This includes all debts that you must declare in box 3. This concerns, for example:
- debts for, for example, a car or a holiday
- negative balance on a bank account
- debt to finance shares, bonds, securities and other investments
- debts for a 2nd home or other immovable property (mortgage)
- debts that you are not allowed to deduct in box 1
- an amount of lifelong learning credit that you must repay
- inheritance tax
- a debt resulting from a donation on paper (except the debt between tax partners or between parents and minor children)
The percentages for investments and other assets are already fixed. The percentages for bank balances and debts are still provisional. We will determine these percentages in early 2025. We use those percentages in your final assessment.

Calculation of your box 3 income for 2024
This is how you calculate the box 3 income in 2024:
- Calculate the taxable return
Use the provisional return rates we mention above to calculate the return per asset type. You assume the value of your assets and debts on 1 January 2024.
Add the return on bank balances to the return on investments and other assets. You reduce the total by the return on deductible debts. This is your taxable return.
- Calculate your capital yield tax base
You also calculate your capital yield tax base. That is your assets minus your debts. You may not deduct your debts in full. You reduce your debts by the threshold (only available in Dutch).
- Calculate your basis for savings and investments
You reduce your capital yield tax base (outcome step 2) by the tax-free allowance. The sum is the basis for savings and investments. You may divide the basis if you have a tax partner. Any division is allowed, as long as the total is 100%.
- Calculate your share in the capital yield tax base
You divide your share in the basis for savings and investments (outcome step 3) by the capital yield tax base (outcome step 2) and multiply it by 100. Round off to 2 decimal points. This percentage is your share of the capital yield tax base.
- Calculate your income from savings and investments
You multiply your taxable return (outcome step 1) by this percentage (outcome step 4). The result is your box 3 income.
- Calculate how much tax you must pay in box 3
Multiply the tax rate for box 3 in 2024 (36%) by the income from savings and investments (outcome step 5).
- 2024 calculation example without a tax partner
You have €150,000 in savings. You do not have a tax partner.
Step 1: calculate the return per asset type
Bank balances: €150,000 × 1.03% = €1,545
The taxable return is €1,545.
Step 2: calculate your capital yield tax base
Assets: €150,000
Deductible debts: €0
Assets: €150,000 - €0 = €150,000
Step 3: calculate the basis for savings and investments
You reduce your capital yield tax base (outcome step 2) by the tax-free allowance. That is your basis for savings and investments.
The tax-free allowance in 2024 is €57,000.
Basis for savings and investments: €150,000 - €57,000 = €93,000
Step 4: calculate your share in the capital yield tax base
You divide your share in the basis for savings and investments (outcome step 3) by your capital yield tax base (outcome step 2) and multiply the outcome by 100. Round off to 2 decimal points.
€93,000 ÷ €150,000 × 100 = 62.00%
Step 5: calculate your income from savings and investments
The income from savings and investments is your taxable return (outcome step 1) multiplied by your capital yield tax base share percentage (outcome step 4).
€1,545 × 62.00% = €957
Step 6: calculate how much tax you must pay in box 3
Multiply the tax rate for box 3 (36%) by the income from savings and investments (outcome step 5).
36% × €957 = €344 tax.
- 2024 calculation example with tax partner and various types of assets
You have a tax partner. You and your partner have the following assets and debts:
- €150,000 in savings
- investments with a value of €75,000
- a 2nd home in the Netherlands with a WOZ value of €200,000
- a debt for the 2nd home of €100,000
Step 1: calculate the return per asset type
Bank balances: €150,000 × 1.03% = €1,545
Investments and other assets: €75,000 + €200,000 = €275,000 × 6.04% = €16,610
The threshold will be deducted from the debt. The threshold is €3,700 per person, making €7,400 for you together.
The deductible debt is: €100,000 - €7,400 = €92,600
The return on the deductible debts is: €92,600 × 2.47% = €2,287.
The taxable return is €1,545 + €16,610 - €2,287 = €15,868.
Step 2: calculate your capital yield tax base
Assets: €150,000 + €75,000 + €200,000 = €425,000
Deductible debts: €92,600
Capital yield tax base: €425,000 - €92,600 = €332,400
Step 3: calculate the basis for savings and investments
You reduce your capital yield tax base (outcome step 2) by the tax-free allowance. That is the basis for savings and investments.
The tax-free allowance in 2024 is €57,000 per person, making €114,000 for you and your tax partner together.
Basis for savings and investments: €332,400 - €114,000 = €218,400.
You may divide the basis for savings and investment between you and your tax partner. Any division is permitted, as long as the total is 100%. In this example, you and your tax partner each declare half of the basis for savings and investment, making €109,200 each.
Step 4: calculate your share in the capital yield tax base
You divide your basis for savings and investments (outcome step 3) by the capital yield tax base (outcome step 2) and multiply the outcome by 100. Round off to 2 decimal points.
Your share: €109,200 ÷ €332,400 × 100 = 32.85%
The outcome of this calculation is the same for your tax partner.
Step 5: calculate your income from savings and investments
The income from savings and investments is the taxable return (outcome step 1) multiplied by your capital yield tax base share percentage (outcome step 4).
Income from savings and investments: €15,868 × 32.85% = €5,212
Step 6: calculate how much tax you must pay in box 3
Multiply the tax rate for box 3 in 2024 (36%) by the income from savings and investments (outcome step 5).
36% × €5,212 = €1,876 tax.
The outcome of this calculation is the same for your tax partner.
- 2024 calculation example with tax partner and various types of assets
You have a tax partner. You and your partner have the following assets:
- €5,000 in savings
- green investments with a value of €150,000
- a 2nd home outside the Netherlands with a market value of €250,000
Step 1: calculate the return per asset type
Bank balances: €5,000 × 1.03% = €51
Green investments are exempt up to €71,251 per person. Making €142,502 for you and your tax partner together. The value of the green investments is €150,000. This means the part above €142,502 must be declared as an asset. In this case that is €150,000 - €142,502 = €7,498.
Investments and other assets: €7,498 + €250,000 = €257,498 × 6.04% = €15,552.
The taxable return is €51 + €15,552 = €15,603.
Step 2: calculate your capital yield tax base
Capital yield tax base: €5,000 + €7,498 + €250,000 = €262,498
Step 3: calculate the basis for savings and investments
You reduce your capital yield tax base (outcome step 2) by the tax-free allowance. That is your basis for savings and investments. The tax-free allowance in 2024 is €57,000 per person, making €114,000 for you and your tax partner together.
Basis for savings and investments: €262,498 - €114,000 = €148,498
You may divide the basis for savings and investment between you and your tax partner. Any division is allowed, as long as the total is 100%. In this example, you specify the entire basis for savings and investment yourself. So €148,498.
Step 4: calculate your share in the capital yield tax base
You divide your basis for savings and investments (outcome step 3) by the capital yield tax base (outcome step 2). Multiply the outcome by 100. Round off to 2 decimal points.
€148,498 ÷ €262,498 × 100 = 56.57%
Step 5: calculate your income from savings and investments
The income from savings and investments is the taxable return (outcome step 1) multiplied by the capital yield tax base share percentage (outcome step 4).
Income from savings and investments: €15,603 × 56.57% = €8,826
Step 6: calculate how much tax you must pay in box 3
Multiply the tax rate for box 3 in 2024 (36%) by the income from savings and investments (outcome step 5).
36% × €8,826 = €3,177 tax.
