Keep in mind that most of the money Norway make from oil & gas are invested [1], it's not money used directly for anything in Norway. Up to 4% of the money made from the investments can be spent, the rest is re-invested.

Of the 1.173,5 bn NOK income in the 2020 national budget, 1.084,8 bn NOK are from taxes and various charges.[2]
