As a student teaching assistant, you provide support for a subject/research and use knowledge specifically from your study to do so. In accordance with the Collective Labour Agreement for Universities, the job classification is based on your academic progress.
The division in pay scales is as follows:
60-120 ECTS = SA2
121-180 ECTS = SA3
>180 ECTS/Master’s student = SA4

You can request the gross hourly wage amounts associated with this from FlexDelft.

When registering for your assignment, the supervisor will indicate the pay scale based on the current number of ECTS. When you receive confirmation of your assignment from us, always immediately check that the job classification is correct.

When you log in, you can go to your timehseets. You will see a small black plus sign (+). When you click on it, a second line will appear with "vacation hours." Here you can submit your vacation hours.

When you log in, you can see how many vacation days you have accrued under "my details.".

If you have earned enough ECTS to move to the next pay scale, you must communicate this to FlexDelft yourself. We can adjust the pay scale based on an ECTS statement, which you can submit to us by email or by dropping it off during opening hours. The new job classification will take effect on the first Monday after receipt of the new ECTS statement.

Anyone employed in the Netherlands is required to pay tax on their salary. This is called payroll tax. Whether and how much payroll tax is withheld depends on a number of factors, including whether or not the payroll tax credit is applied and your gross weekly income.

If you work, you are entitled to a tax credit.
When you apply the payroll tax credit, less tax is withheld from your salary than when you do not apply the credit. You can only apply the payroll tax credit with one employer. You should choose the employer where you earn the most. When you enrol with FlexDelft, you fill in a form indicating whether or not you want to apply the payroll tax credit. You can always change this at a later date by sending us an email or stopping by in person.
Find more information about payroll taxes from the tax authorities here vinden.

Stop by our office or send us an email to change your payroll tax credit. We will then send you a form to complete and return to us by email.
You can only apply a payroll tax credit with one employer.

You will receive a payslip when you have been paid for hours worked or when we have paid out holidays, holiday pay or year-end bonus.

Under the ‘Declaration' heading on your payslip, you will find the total hours worked, your gross hourly wage and the total gross wage to be paid (hours worked x gross hourly wage).

An explanation of the calculation from gross wage to net wage can be found under the ‘Description’ heading on your payslip.

For payroll tax, the more you work per week, the more payroll tax you pay. If the payroll tax credit is applied (you can find this at the top right of your payslip), payroll tax is withheld starting from about eight hours a week. You can file a tax return every year in March to get a refund of any overpaid tax.

Your accrued holidays and holiday pay are shown at the bottom of the payslip. Holiday pay and holidays are separate pots that accrue with a percentage of the gross salary paid by us. Finally, the same table shows the change in the balance (holidays in hours, holiday pay in euros) as a result of us paying your wages and/or you having holidays paid out.

If you do not declare any hours for six weeks, all your accrued reserves (holiday pay, holiday hours and end-of-year bonus) will be automatically paid out.
Your accrued holiday pay balance is automatically paid out in May.
Your accrued year-end bonus balance will be paid automatically in November.

You can also include holiday hours in your declaration of hours worked, provided you declare hours in the same week.
Want to take holiday hours in a week you don't work? Send us an email and we will process it for you.

We advise you to submit your hours worked at the end of each week. Once you have submitted your declaration, it is final and you cannot amend it. The person approving your submission can change the number of hours.

Once you have submitted your declaration, it cannot be reversed. If possible, try to offset the incorrectly submitted hours with a declaration for another week.

The person approving your submission can change the number of hours or set it to 0 hours.

Yes, you can change your address in your account or send an email.

Note: To work through FlexDelft, you must be registered at a Dutch address.

You can no longer submit declarations once the end date of your assignment has passed. Visit your supervisor and have them notify FlexDelft of an extension of your assignment.

Once the maximum number of submitted hours has been reached, you can no longer submit hours. Visit your supervisor and have them notify FlexDelft of an increase in your hours.

You can submit declarations from up to four weeks prior. Everything before that will automatically lapse. Should you wish to submit hours from more than 4 weeks ago, please send us an email.

Your supervisor may not have approved your submitted declaration yet. Check in the timesheet portal whether your declaration has been approved. All declarations approved by 9.00 am on Tuesday morning will be paid on Tuesday.
