Tax return 2017 due before 1 May
To start with some good news: often, you are not obliged and it is not worthwhile to file a Dutch tax return. This will be the case if you only had Dutch employment income during the complete calendar year and are not entitled to any deductions (like mortgage interest) and did not receive an invitation (blue envelope) to file a Dutch tax return.
When to file
In the following situations it is required or can be worthwhile to file a Dutch tax return:
- You are invited to file your Dutch income tax return
- You arrived or left the Netherlands during the year
- You paid mortgage interest on your own house in the Netherlands
- You paid alimony payments, educational or other deductible expenses
- You may expect that Dutch income tax is due
In the Netherlands the tax year coincides with the calendar year. Your 2017 Dutch income tax return must be submitted before 1 May 2018. You may request for a further extension, but this should be filed before 1 May 2018. You can do so by contacting the tax authorities directly or your tax adviser.
How to file
You can file your Dutch tax return via the website of the Dutch tax authorities. However, this is only available in Dutch and you will need your DigiD. Please note it may take a few weeks to arrange for your DigiD, so if you do not have one yet, we advise to apply for one as soon as possible (at www.digid.nl). You will also need this DigiD to activate your account at www.MijnOverheid.nl, which is used for digital communication with the Dutch tax authorities.
In case you need help
Leiden University has concluded a favourable agreement with LIMES international tax + expat BV (“LIMES”) regarding practical assistance with your Dutch tax issues. Please note that you are of course at liberty to contact your own tax advisor. Nevertheless, if you are interested in contracting LIMES to file your tax return please contact the Service Centre International Staff (SCIS). They will provide you with an application form, including rates, terms & conditions. Meetings will take place at the premises of Leiden University if they can be combined with meetings of other Leiden University employees. SCIS can also help you with the application of your DigiD, provided you bring your BSN.
