Yes. There is a minimum purchase amount for Tax Free shopping in Norway.
The minimum spend depends on the type of goods you purchase:
Most goods (25% VAT): NOK 315 including VAT
Food (15% VAT): NOK 290 including VAT
The minimum amount applies to a single receipt.
You can purchase multiple eligible items in the same transaction - as long as the total amount on the receipt meets the minimum spend.
Good to know
Purchases from different stores or separate transactions cannot be combined to reach the minimum amount.
