You will face 2 kinds of taxes: (1) turnover tax and (2) income tax.
If you independently run a company or job, you should pay taxes over your revenue. Turnover tax is also known as the VAT-declaration. You declare VAT online, using your digital portal of the Belastingdienst (Tax Authorities). If this is your first VAT-declaration, then you might need to do this by hand on paper forms sent to you by the Tax Office. If you registered as a freelancer, you will be notified via post about which quarter you need to do turnover tax. Probably, you need to do this every quarter. You can request at the Belastingdienst to do this monthly or yearly.
How much you have to pay depends on the number of hours you’ve worked and how much you’ve earned per hour. You are also required to declare your VAT when you have earned € 0,-. On your invoices, you can exactly see how much VAT you’ve received.
The moments when you need to declare your turnover tax if you declare it every quarter:
Your declaration over quarter 1 (January, February, March) should be done before 30 April.
Your declaration over quarter 2 (April, May, June) should be done before 31 July.
Your declaration over quarter 3 (July, August, September) should be done before 31 October.
Your declaration over quarter 4 (October, November, December) should be done before 31 January.
Tip: download the app Btw-Alert offered by the Tax Authorities and always receive a reminder when you have to declare your turnover tax.
If you live in the Netherlands or have income from the Netherlands, you should pay taxes on that income. You pay taxes on income, financial interests in a company and on your savings and investments. The Belastingdienst (Tax Authorities) collects the income tax. The declaration of your income tax is done every year in April.
