Onshore wind parks /periodandyear/help/taxation/impersonal/information/basis-values/onshore-wind-parks section 2025-03-28T16:20:53+01:00 # Onshore wind parks Onshore wind power can be activated for a client by opening **Edit areas** under **Year-End closing** - **Information and Tax** - **Information**. The feature consists of two menu items: - Onshore wind parks - Contracts in onshore wind farms Individual wind farms are registered in the **Onshore wind parks** menu. > [!NOTE]Read more about 'Resource rent tax on onshore wind power' >The Tax Administration has a dedicated information page for [Resource Rent Tax on onshore wind power](//www.skatteetaten.no/en/business-and-organisation/reporting-and-industries/industries-special-regulations/kraft/vindkraft/grunnrenteskatt-pa-landbasert-vindkraft/), which is important to familiarize yourself with. ### Menu Onshore wind parks On the **Information** tab, it is important to register the correct values in the field **Installed capacity in MW according to the concession** and in the field **Number of turbines**, as these fields are crucial for determining tax liability for resource rent income. On the **Income** tab and the **Deductions** tab, some fields will be calculated based on registered contracts, while other values are entered manually. The calculations may be possible to override on some values. The **Resource Rent Tax** tab shows the sum of income from the **Income** tab, while the total deductions from resource rent income are the sum from the **Deductions** tab, plus corporate tax from the **Corporate Tax** tab. On the **Corporate Tax** tab, depreciation deductions must be calculated and registered. These fields are not calculated by the Tax Administration. These calculations are complex. The Tax Administration provides information on these calculations from the webinars held in the fall of 2024, available on [Tax administration pages](//www.skatteetaten.no/bedrift-og-organisasjon/rapportering-og-bransjer/bransjer-med-egne-regler/kraft/vindkraft/grunnrenteskatt-vindkraft/#webinarer).

Calculations made from contracts and internally on the Wind parks tab require you to be logged into the Tax Administration system, as the Tax Administration’s calculations are linked to the menu item.

### Menu Contracts in onshore wind farms Here, the various contracts for the sale of wind power are registered. Information on income, gains, and losses from these contracts will be transferred to fields on the **Income** tab under **Onshore wind parks**. Make sure to specifically check that gains and losses are included. Gains and losses from early termination will be transferred to separate items on the income tab. #### Investment cost (direct deduction) The company can directly deduct the current year's costs related to onshore wind park from the basis for resource rent tax when the fixed asset is used in resource rent taxable activities. Information about fixed assets used in resource rent taxable activities must also be provided under the **Fixed assets** section. #### Depreciation of other fixed assets this year Depreciation of assets that are not directly deducted may be deducted from resource rent income according to special rules. Information on fixed assets used in resource rent taxable activities must also be provided under the **Fixed Assets** section. See separate instructions for these fields under [Fixed Assets in onshore wind parks](/periodandyear/help/taxation/impersonal/information/basis-values/onshore-wind-parks/fixed-assets). #### Gains and Losses on realization of fixed assets When realizing assets that are to be depreciated in resource rent income, the rules for deductions when determining ordinary income in Chapter 14 of the Tax Act, along with the special rules for wind power plants, apply. For assets that have been directly deducted from resource rent income, the entry value should be set to zero kroner. ### Tax calculation and posting of tax expenses For onshore power parks, there are specific reference accounts for tax expenses and balance sheet tax: - 1591 Tax value of carried forward negative resource rent income for onshore wind power - 1592 Carried forward production fee for onshore wind power - 2505 Payable resource rent tax for onshore wind power, not yet assessed - 8305 Resource rent tax for onshore wind power In the tax calculation, the tax calculation from the Tax Administration will be read, and the following values are used: - Value from the field **Resource Rent Tax in onshoew wind power**: Payable tax to be credited to account with reference account 2505 Payable resource rent tax for land-based wind power, not yet assessed. - Value from the field **Carryforward production fee including interest**: Future tax due will be debited to the account with reference account 1592 Carryforward production fee for onshore wind power. - Value from the field **Carryforward negative resource rent income including interest**: Future tax due will be debited to the account with reference account 1592 Carryforward production fee for onshore wind power, with the field value multiplied by the resource rent tax rate, which for 2024 is 31.2%. - The offset to changes in the value of the mentioned 3 accounts will be the account with reference account **8305 Resource rent tax for onshore wind power**. The calculated values can be overridden in the tax expense page and will then be posted with the overridden value. Notes will also use the overridden value. If an account does not exist, the account will be created automatically. In the note to the public financial statements, the balance from the mentioned accounts will appear in both tax expense and balance sheet tax.

Wind parks companies with participant taxed

Companies with participant taxation will automatically calculate positive or negative resource rent income for participant reporting.

For participants in wind park companies with participant taxation, there are separate items in the participant statement where values can be registered, which will also be retrieved from a potentially pre-filled tax return with these items.

 Fixed assets in onshore wind power /periodandyear/help/taxation/impersonal/information/basis-values/onshore-wind-parks/fixed-assets page Fixed assets, depreciation and direct deduction 2025-05-21T14:33:14+02:00 # Fixed assets in onshore wind power Fixed assets, depreciation and direct deduction There are specific rules for adjusting the depreciation base for assets acquired before 01.01.2024, and these calculations must be made for each individual asset for non-depreciable assets, linearly depreciated assets, and for each balance for balance-depreciated assets. If an asset or balance concerns assets both within and outside the resource rent taxable activity, they must be split into two parts: one for resource rent taxable activity and one outside the resource rent area, to ensure that depreciation, gains, and losses within and outside the resource rent area can be reported separately in the future. Alternatively, separate reports outside of Period & Year with these calculations must be kept. The latter option will require overrides for individual assets or balances for each year, and it is not recommended. > [!NOTE]Read more about 'Fixed assets in onshore wind power' >The specific transition rules for fixed assets can be found on the Norwegian Tax Administration's website, under the section for [Resource rent tax on onshore wind power](//www.skatteetaten.no/en/business-and-organisation/reporting-and-industries/industries-special-regulations/kraft/vindkraft/grunnrenteskatt-pa-landbasert-vindkraft/). The cost price of tangible fixed assets reduces taxable income according to several different regulations that must be treated separately: - Depreciation, gains, and losses under the normal rules for calculating the company's general income - Depreciation of the adjusted depreciation base as of 01.01.2024, with one-fifth annual depreciation for resource rent income - Direct deduction of acquisitions that can be directly deducted from the resource rent income - Depreciation of assets that are to be deducted in the calculation of corporate tax in the resource rent income Taxable objects can be one of the following: - Balance depreciation of assets in balance group e-j (special balances for each unit) - Balance depreciation of the master balance in balance groups a, c, and d - Non-depreciable assets - Linearly depreciated assets #### Used in resource rent taxable activities Here, the company must specify whether the taxable object is an asset used in resource rent taxable wind power installations. It is recommended to separate the objects so that there are separate master balances in groups a, c, and d for each wind park and for those outside the resource rent taxation. For other assets with mixed use, it is also recommended to separate assets into their own objects for each wind park and areas outside the resource rent zones. No deduction is allowed for activation costs for the acquisition of land or other payments to landowners, rights holders, municipalities, etc., as mentioned in the Tax Act § 18-10 third paragraph letter a number 1 third sentence, nor for costs related to the acquisition of existing wind power installations. These objects must therefore be treated as objects outside the resource rent area. Wind power installations that are realized without taxation, cf. Tax Act § 18-10 seventh paragraph letter b, must be treated separately regarding the continuation of the seller's tax positions. If the depreciation applies to assets linked to several wind power installations, the depreciation must be allocated between the wind power installations. It is recommended that for Period & Year, one object is created for each wind power installation, so that automatic calculations can be applied without the need for overrides. #### Separate treatment of assets acquired before 2024 and assets acquired in 2024 or later Assets acquired before 01.01.2024 shall have a new depreciation base calculated, which is only used when determining resource rent income, and this new depreciation base is depreciated with one-fifth annually from 2024 to 2028. Acquisitions made from 2024 onward will be directly deducted from the resource rent income. It is recommended to separate balance depreciation and other taxable objects from previous years and new objects to ensure that assets acquired before 01.01.2024 and assets acquired in 2024 and later are not recorded on the same balance or the same taxable object, thus simplifying the calculation of taxable depreciation. #### Directly expensed investment costs These are taxable objects marked with **Yes, with direct deduction**, but the field can be overridden if desired. Overriding is not necessary if assets acquired before and after 01.01.2024 are kept separate. The direct expensed investment cost for resource rent income in this year is entered in this field as an amount in NOK. This applies to investments made from 01.01.2024. On the **Wind Power** tab **Deductions**, the directly expensed investment cost will be deducted from the corresponding field in the depreciation of taxable objects. On the **Wind Power** tab **Corporate Tax**, the directly expensed investment cost will be reversed and replaced by the regular taxable depreciation of the same objects marked with **Yes, with direct deduction**. This field can also be overridden. #### Fixed assets from previous years The taxable value as of 01.01.2024 and the adjustment of the balance as of 01.01.2024 according to the specific rules for wind power installations must be registered manually, and depreciation of the depreciation base will be distributed with one-fifth depreciation in 2024 and the following four years (2025-2028) until the recalculated taxable value is fully depreciated in the resource rent income. Depreciation in resource rent tax with one-fifth annually from taxable depreciation will automatically transfer to the field for depreciation under **[Wind Power Installations](/periodandyear/help/taxation/impersonal/information/basis-values/onshore-wind-parks)** tab **Deductions**. > [!IMPORTANT] > On the **Wind Power**-tab **Corporate Tax**, depreciation in resource rent tax will be reversed and replaced by taxable depreciation under other rules. These depreciations must be calculated separately and registered on this page. > > The specific transition rules for assets can be found on the Norwegian Tax Administration's website, under the section for [Resource Rent Tax on onshore wind parks](//www.skatteetaten.no/bedrift-og-organisasjon/rapportering-og-bransjer/bransjer-med-egne-regler/kraft/vindkraft/grunnrenteskatt-vindkraft/).
