The Norwegian Government has announced that Corporation Tax will be reduced by 2% to 25%. The marginal tax rate for petroleum activities will remain at 78%, as the Special Petroleum Tax rate will be increased by 2% to 53%. The change is part of wider tax reforms to boost Norway's competitiveness in non-oil sectors. Further tax reforms are proposed in a white paper published alongside the budget, with Corporation Tax to be reduced to 22% by 2018. In order to avoid a reduction in state revenue, further adjustments will be required to the Special Petroleum Tax and could require a review of the capital uplift rate.
