During the year you are assessed as a business, you can have up to the previous five years approved as start-up years for your business. You can claim a deduction for costs you incurred during those start-up years. Use form RF-1298 Oppstart av virksomhet (Starting a business - in Norwegian only). This form is included in the Business Tax Return. You will find more information on start-up periods and the development of a hobby into a commercial enterprise with examples under ‘Hobby or business’.
Costs you have incurred in generating taxable income will generally give entitlement to a deduction. Read about how to depreciate purchases costing less than NOK 15,000 or more than NOK 15,000.
You must be able to document all costs for which you are claiming a deduction.
