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.

• Income statement for a request for a lower monthly instalment 2025pdf, 251kb

If there is foreign income, we need an income statement from the tax authorities of the country in question or an income tax assessment. This document is also required if you have no income.

The statement must be submitted in Dutch or English. Is the statement in another language? Then have the statement translated and enclose a copy of the original statement.

• Is the income on the statement lower than the equivalent of €8,000? If so, you need to include evidence of the additional nontaxable benefits you received.
• 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.
• 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.
• 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.
• 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.
• 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.
