How do you get a tax ID number in the Netherlands in 2026?

Register as a resident for stays over four months, or use the RNI route for shorter or non-resident cases: Register your address and get a BSN. That BSN is what employers put on wage tax, what banks ask for, and what Belastingdienst uses in its systems. There is no parallel federal tax-ID mailing like Germany’s after Anmeldung.

Apply for DigiD next so you can open Mijn Belastingdienst and Mijn toeslagen: Set up DigiD. Activate MijnOverheid message box when you can, so tax and toeslag letters do not die in unread post. A Dutch payment account helps for refunds and premiums: Open a bank account.

Check whether you must file an income-tax return for the year you moved; Belastingdienst often sends a letter, but you can verify inside the portal. National insurance and healthcare contributions usually attach when you are socially insured in the Netherlands. Claim zorgtoeslag or huurtoeslag separately if you qualify: Apply for housing and care benefits. Highly skilled employees may add the expat scheme file with their employer: Apply for the 30% ruling.

Health-insurance obligation still sits beside tax, not inside it: Choose health insurance. Keep the BSN-first order in Paperwork after moving.
