Calculate Proportional VAT
You can use proportional VAT to calculate VAT when there is both deductible and non-deductible VAT. Because it is difficult to know where and how an item is used, you will have to contact the Norwegian tax authorities to determine whether a specified percentage of the VAT is deductible based on historical data.
