Your income

When calculating your monthly instalments we usually take your income into account. Read which income we use and what to do if your income has dropped.

Which income?

We look at your income and your partner's, if you have one, from 2 years ago. We call this the reference year. We obtain the details of your income from the tax authorities (Belastingdienst). If you file tax returns, we consider your aggregate income. Otherwise, we use the taxable salary shown on your annual tax assessment(s).

If we cannot get your income details, we will send you a notice. The notice explains how to provide us with your income details in Mijn DUO.

Not including your partner’s income

Do the SF15-old repayment rules apply to you? If so, you can ask DUO not to include your partner’s income. You can do so in Mijn DUO.

If you choose not to include your partner’s income, the duration of the repayment phase will be frozen. This means you remain obliged to pay back your loan for as long as you don’t include your partner’s income, until you have paid back your loan in full. The repayment phase will not expire until you no longer have a debt. There will be no cancellation of any remaining debt.

As soon as you start including your partner’s income again, the duration of the repayment phase continues again as well. Once the repayment phase expires, any remaining debt will be cancelled. Any overdue instalments are not cancelled.

Relationship ended

Inform us through Mijn DUO if your relationship ends. We will make sure the duration of the repayment phase continues again.

If you cannot log in to Mijn DUO, please use the 'Changes loan repayment’ form.

Changing your partner’s details

Your partner’s income is included from the month after you have a partner. If you have a new partner, or your relationship ends, your monthly instalments may be affected. Fill out the Personal details update assistant and read what to do.

Falling income

If your income has fallen since the reference year, you can ask us to look at a more recent year. We call this changing the reference year.

Income outside the Netherlands

If you have a foreign income, we are often unable to request details from the relevant tax authorities. In these cases, you have to notify us yourself of your income before taxes. We send you a letter about this every year. After this, you can inform us of your income in Mijn DUO.

No access to Mijn DUO

If you have no access to Mijn DUO, you can use the Opgave inkomen voor verzoek lager maandbedrag form.

Supporting documents of foreign income

As proof, we require the income figure determined by the tax authorities in the country where you live and/or work. This is known as an income statement or an income tax assessment. This may include income from employment, benefits, a pension, self-employment, real estate, savings, or shares. Are you not required to file a tax return? You should file one anyway in order to obtain the necessary proof.

Translation

The statement or proof must be in Dutch or English. Many tax authorities allow you to request an English-language version in addition to the version in the local language. You may also translate the documents yourself, but the translations must be complete, not just of a few words on the document. Please also submit a copy of the original document.

Self-employed

Are you a business person and does the income statement not state a basis for profit tax? In that case, you will need to include an accountant’s statement detailing the profit tax. That can be the profit statement before profit tax.

Are you self-employed and have you been granted a deferral in submitting your tax return? Then you need to send a statement of income from your accountant. This must show your full income (and the profit) for the entire year.

Reduced income

Do you want to change the reference year to a year that has not yet passed? Then you must enclose pay slips for the months in that year that have already passed.

Outside the EU/EEA

Do you live outside the EU/EEA and is it not possible to get an income statement from the tax authorities? If so, you must enclose a copy of the annual statement or a copy of all pay slips.

In some countries, the income statement from the tax authorities might be called differently. The table provides more information on the required supporting documents for a number of countries.
