Tax cards
When you start receiving SU, the Danish Tax Administration are notified automatically and will then generate a primary and secondary tax card for you. They also decide the percentage of your income that you must pay in tax. Your primary tax (hovedkort) card is used for your primary income, for example SU. You can use your secondary tax card (bikort) for any other income.
It is your responsibility to make sure that you pay enough tax and that your primary and secondary tax card are used as you wish. If you wish to use your secondary tax card for your SU, you should let us know via minSU.
If you stop receiving SU or if you work while receiving SU, you should always change your preliminary income assessment.
Maximum income from a student job
When a year is over, we will check any private income you may have had beside your SU. If you have earned more than a set amount (fribeløb), you will have to return some of your SU and SU loans.
