A Norwegian resident company is, as a starting point, subject to corporate income tax (CIT) on its worldwide income. Non-resident companies are, as a starting point, liable for CIT in Norway when engaged in a business that is either conducted in or managed from Norway.
CIT is, in general, assessed at a rate of 23%. Certain companies within the financial sector are assessed at a CIT rate of 25%.
As a general rule, income is taxable when the right to receive it arises and costs are deductible when the liability to cover the costs arises. The actual payment is generally not relevant.
Petroleum tax regime
All upstream petroleum activity on the Norwegian Continental Shelf (NCS) is taxable to Norway.
Taxation is based on net income at a marginal tax rate of 78%, which is comprised of the ordinary 23% CIT rate and a 55% special tax. All income is subject to 23% CIT, while only income from offshore production and pipeline transportation of petroleum from the NCS (offshore tax regime) is subject to the additional 55% special tax. The ordinary and special tax rates were changed in 2018 (from 24% and 54%, respectively, in 2017). However, the marginal tax rate remains the same, and the purpose of the changes in the special tax rate (from 54% to 55%) and uplift (from 5.4% to 5.3%) is to leave the deduction value of the uplift unchanged (see below).
All upstream activity on the NCS must be consolidated within the company. There is no ring fence per oil field, and tax consolidation against other activity is limited. Crude oil sales from most of the fields are taxed at a predetermined market price set by an official board (i.e. the norm price). In theory, a norm price may be imposed on gas sales, but this has not been implemented. Instead, an extensive reporting requirement was implemented in October 2012. Investments in installations for the exploitation and production of petroleum, as well as investments in pipelines, are depreciated linearly over six years.
An investment-based ‘supplementary depreciation’ (uplift) of 21.2% (5.3% per year for four years) is granted on investments in installations for the exploitation and production of petroleum, as well as investments in pipelines. The rate was reduced from 5.4% in 2017 to 5.3% in 2018. The new rate applies for investments made on or after 1 January 2018. Special transitional rules apply for investments made before 5 May 2013, and an uplift rate of 7.5% may still apply in some cases. The uplift is deducted against the special tax base. Losses and unused uplift may be carried forward indefinitely with an annual interest. Both depreciation and uplift may be claimed from the year of the investment, regardless of whether title has passed or the asset has been taken into use. If the upstream activity on the NCS ceases, the tax value of losses carried forward and unused uplift may either be sold or compensated by the Norwegian state. Exploration costs are tax deductible as incurred. If a loss is created due to exploration costs, the taxpayer may claim that the tax value of such a loss is repaid in the year following the income year in which the loss was created.
Special rules apply as to the deductibility of net interest costs in the special tax basis (55%).
A special regime ensures that transfer of licences on NCS is tax exempt; there is no step up in the tax basis.
Note that dividends that stem from income subject to the special tax regime are exempted from dividend WHT.
The Oil Taxation Office (OTO) has a special responsibility for the taxation of the petroleum sector. Generally, the OTO has a high focus on transfer pricing.
Hydro power tax regime
The hydro power tax regime is applicable for the taxation of income derived from the production, sales, transfer, or distribution of hydro power.
Taxation is based on net income at a marginal tax rate of 58.7%, which is comprised of the ordinary 23% CIT rate and a 35.7% resource rent tax. All income is subject to 23% CIT, while only income from hydro power production is subject to the additional 35.7% resource rent tax.
The resource rent is calculated per hydro power plant. The gross income is, with some exceptions, calculated based on spot market price per hour multiplied by actual production. In addition, actual income from green certificates is included in the gross income. Deductible costs will be the same as for CIT; that is, expenses related to the power plant except for interest expenses, which are not deductible. Uplift is granted. Special rules apply to the depreciation of investments in hydro power plants. Rent expenditure and depreciation related to waterfalls are not deductible, and waterfalls are not included in the basis for uplift. Tax consolidation is mandatory within the company and, provided the conditions for group taxation are fulfilled, available on a group level. Losses (negative resource rent) on a company (eventually on a group) level will be compensated by the Norwegian state.
Shipping tonnage tax regime
The tonnage tax rules in Norway are in line with those found in other European Union (EU)/European Economic Area (EEA) countries and imply that shipping income will be tax-exempt on a permanent basis. On 14 December 2017, the European Free Trade Association (EFTA) Surveillance Authority (ESA) announced that the Norwegian tonnage tax regime is approved for a new ten-year period, with certain amendments.
Norwegian tonnage-taxed companies are allowed to keep only certain kinds of assets inside the tonnage regime (legal assets) and are not allowed to have income from non-tonnage-taxed activities except financial income. If the requirements are not fulfilled, the company will fall outside the scope of the model and be taxed at the ordinary rate (23%).
A tonnage-taxed company must own at least one qualifying asset (i.e. a vessel, for example bulk tankers, container vessels, car carriers, tugboats, and entrepreneurial vessels and auxiliary vessels for use in the petroleum industry), new building contracts, a 3% share in another tonnage-taxed limited company, or a 3% ownership interest in a qualifying partnership or controlled foreign company (CFC).
One of the important amendments from the ESA announced in December 2017 relates to the inclusion of windmill farm entrepreneurial vessels to the regime. More precisely, this means that vessels engaged in the construction, maintenance, repair, and disassembly of windmills at sea are eligible under the scheme as of the income year 2017.
Non-self-propelled barges are eligible for the tonnage tax regime with effect from 1 January 2018, provided certain conditions are met.
Qualifying and legal business activities/income
Qualifying business income is income from the operation of the company’s own and chartered vessels. With effect from 1 January 2018, there are limitations on chartering out vessels on bareboat. The limitations on bareboat chartering out in the approved regime are different for vessels in the offshore sector and vessels outside the offshore sector (traditional shipping). The following limitations apply for bareboat chartering out in the offshore sector:
- Chartering out on bareboat terms may not exceed 50% of the company's fleet during an income year, alternatively over a period of four years.
- Bareboat chartering out must not exceed a contract period of five years, with a possibility to extend the contract by another three years.
- The strategic management of vessels chartered out on bareboat terms must be carried out from an EEA state.
On bareboat chartering out outside the offshore sector, a distinction must be made between contracts regarded as operational lease and financial lease.
Chartering out on contracts regarded as financial lease are not permitted under the regime.
Bareboat contracts regarded as operational lease are allowed with the following limitations:
- Chartering out on bareboat terms may not exceed 40% of the fleet per income year, alternatively over a period of four years.
- The chartering period may not exceed one half of the vessel's life-time.
- The strategic management of vessels chartered out on bareboat terms must be carried out from an EEA state.
For both the offshore sector and traditional shipping, the share of allowed bareboat chartering out is measured on group level.
The limitations on bareboat chartering out will not apply to existing contracts that are not regarded as long-term. The assessment of what constitutes a long-term contract are different in and outside the offshore sector. Further, a transitional period will be implemented for the companies subject to the updated rules.
Chartering in of vessels on time-charter terms is, with effect from 1 January 2018, limited to 90% of non-EEA flagged vessels. These rules are not applicable for existing time-charter contracts.
Furthermore, gains upon disposal of vessels and new building contracts are exempt from taxation.
Income from related activities, such as the sale of goods and services onboard vessels, loading and discharging vessels, or leasing out containers and operations of ticket offices, is also exempt from taxation. The exemption also applies to income from the strategic and commercial management of the company’s owned and chartered vessels, as well as vessels owned or operated by group companies (more than 50% joint ownership), and vessels operated according to a pool agreement. Pure management companies are not included (i.e. all companies must have at least one qualifying asset).
Financial income is permitted, except for income from shares in unlisted companies and ownership interests in partnerships that are not taxed under the tonnage tax system. The condition is that financial activities do not constitute a separate business. Net financial income is subject to ordinary taxation (23%). Currency gains and losses are partly taxable/deductible, and interest costs are partly deductible, depending on the proportion between the company’s finance capital and total book capital.
Entrance into the tonnage tax system
Entry into the tonnage tax system is optional and may take place with effect from 1 January every year, provided that the company has fulfilled the conditions for the application into the tonnage tax system from the beginning of the year. Newly established companies will have direct entry and may enter into the tonnage tax system from the date of incorporation. All qualifying companies within the same group are obligated to make the same election (tonnage taxation or ordinary taxation).
Companies that enter into the tonnage tax system are subject to a formal ten-year lock-in period. If a company exits the tonnage tax system before the lock-in period expires, it will be excluded from the tonnage tax system until after the initial lock-in period has ended.
Upon entry into the tonnage tax system, the difference between market value and tax value of the company’s assets (including vessels, new building contracts, ownership interests in partnerships, and shares in CFCs/tax exempt assets) is taxed as a capital gain (23%) that can be transferred to the gain and loss account. 20% of the balance will be entered as income each year (balance method). There is continuity for financial assets and assets covered by the tax-exemption rules (qualifying shares and derivatives).
Exit from the tonnage tax system
A shipping company may exit the regime on a voluntary basis or may be obligated to do so after breaching specific company requirements within the tonnage tax system. There should be no exit charge when leaving the regime, and the tax value on the company’s assets will be adjusted to market value at the time of exit. However, a company that has untaxed gains calculated upon entry into the tonnage tax system could have a tax liability upon exit.
Local income taxes
There is no county or municipal CIT in Norway.
