Since 2020, every freelancer in the Netherlands has had two VAT numbers. It sounds redundant, but it actually makes sense.
VAT identification number (btw-id)
This is your public number.
You use it on your invoices, website, and in the YoungOnes app.
Turnover tax number (OB-nummer)
This is your private number for the Tax Authorities.
You only use it for your VAT returns and communication with the Tax Authorities.
Are you starting as a freelancer now? Then you will automatically receive both numbers as soon as you register with the Tax Authorities or via the KvK. You do not need to apply for anything extra.
Were you already a freelancer before 2020? Then you received a letter at that time with your new VAT ID. Your old VAT number was converted into the current turnover tax number at that time.
