Supplementary grant

If you are eligible for student finance, you can apply for a supplementary grant. The supplementary grant depends on your parents’ income. We use their income data from 2 years ago.

How much is it?

Use the calculator to find out what the income limit is and how much supplementary grant you can get.


When you apply for student finance, you can apply for the supplementary grant at the same time. You can also apply for it later via Mijn DUO.

Login problems

If you cannot log in to Mijn DUO, then you can use a form. For university or higher education, use Wijzigingen student hoger onderwijs. For secondary vocational education, use Wijzigingen student mbo.

Gift or loan

Your supplementary grant is a gift for your first 5 months of higher education (or the first 12 months of secondary vocational education). The rest will be converted into a gift if you gain your diploma within 10 years.

Not the full supplementary grant?

If you do not qualify for the full supplementary grant, you can still borrow the shortfall as a loan. This means that every student can receive the same amount of student finance every month.

Parental income decreased

If your parents’ income has decreased by at least 15%, they can request to have the reference year changed to a more recent year. This may mean that you qualify for a (larger) supplementary grant. If this applies to you, please contact our Customer Service Department. We prefer to explain this procedure to you personally.

Problems with your parents

You can request to leave your parents’ income out of consideration completely, for example because you have a serious and persistent conflict with one or both of them. If this applies to you, please contact the department which handles these requests by calling +31 50 599 83 43. We are available on workdays between 10 a.m. and noon. We prefer to explain the procedure to you personally.

Income outside the Netherlands

If your parents have a foreign income, we are often unable to request details from the relevant tax authorities. In these cases they have to notify us themselves. We send them a letter about this every year. In this letter we ask your parents to notify us of their income before taxes, and to send us the supporting documents we need. They can do so in Mijn DUO.

Log in problems

If your parents cannot log in to Mijn DUO, they can use the Opgave inkomen buiten Nederland form. If both of your parents received a letter, they each need to send a form.

Supporting documents of foreign income

If there is foreign income, we need an income statement from the tax authorities of the country in question. This document is also required if your parent has no income.

The statement must be in German, English, French or Dutch. Is the statement in another language? Then send us a translation together with a copy of the original statement.

  • Is the income on the statement lower than the equivalent of €8,000? If so, we need evidence of the additional nontaxable benefits your parent received.
  • Is your parent self-employed, and does the income statement not state the profit before tax? Then your parent needs to send a statement from the accountant mentioning the profit before tax. Or the tax bill for the profit tax.
  • Does your parent live outside the EU/EEA and is it not possible to get an income statement from the tax authorities? If so, your parent must enclose a copy of the annual statement or a copy of all pay slips.
  • Does your parent want to change the reference year to a year that has not yet passed? Then your parent must enclose pay slips from that year for the months that have already passed.
  • Are your parents self-employed and have they been granted a deferral in submitting their tax return? Then they need to send a statement of income from their accountant. This must show their 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.

Income in the Dutch Caribbean

Curaçao, Bonaire, Saba or Sint Eustatius

Do your parents live on Curaçao, Bonaire, Saba or Sint Eustatius? If so, we will send them a letter, asking them to notify us of their income. They only need to do so once. After this, we will annually ask the tax authorities for information on their income. If this does not work, they will need send a Verklaring inkomstenbelasting form to notify us of their income.

Sint Maarten or Aruba

If your parents live on Sint Maarten or Aruba, they need to send a Verklaring inkomstenbelasting form each year to notify us of their income.

Supporting documents

One of the following documents needs to be sent with the Verklaring inkomstenbelasting form:

  • A statement on the form itself, from the tax authorities of the island in question (question 4)
  • A form called Informatie Beheer Groep Studiefinanciering Verklaring Inkomstenbelasting voor belastingplichtigen binnen de Nederlandse Antillen (issued by the Inspectie der Belastingen Curaçao)
  • A Machtiging Verklaring Inkomstenbelasting voor belastingplichtigen op Aruba, Curaçao, Sint Maarten of Caribisch Nederland (issued by the Belastingdienst/Tax Administration)

The supporting documents must be signed and stamped by the local tax authorities.

Parents are refugees

Are your parents refugees in the reference year? If so, we understand that they cannot supply their income data. Instead, send us a letter about your parents’ situation in the reference year. For instance, are they living in a refugee camp, on the move or staying in a refugee shelter.

Have your parents been recognized as refugees in a safe country? Then we need an income statement from the tax authorities of this country, covering the period from the recognition. If your parents have been recognized as refugees in the Netherlands, you do not need to take any action. We will receive their income data automatically.
