As a result of the March 2012 Budget HMRC will be issuing a CT600 Budget Insert (March 2012) and updating the CT600 Guide. There are changes to the Controlled Foreign Companies (CFCs) rules, Research and Development (R&D) Relief, and supplementary charge in respect of ring fence trades. A reduced rate of Corporation Tax for profits attributable to patents and other intellectual property has also been introduced.
The main rate of Corporation Tax for 2012 is 24 per cent and the small profits rate is 20 per cent. The standard Marginal Relief fraction is 1/100. The rates for ring fence profits are unchanged.
An announcement in the 2012 Budget means HMRC will be updating the CT600B guidance that explains the circumstances under which a company is required to provide details of its overseas subsidiaries, commonly known as CFCs. A CFC is a non-UK resident company which is controlled by a UK resident person or persons. The details required will continue to include amounts of a CFC’s profits that are apportioned to a UK company and subject to tax.
The CFC legislation has been rewritten and the new rules will apply to accounting periods beginning on or after 1 January 2013, by reference to the accounting period of the CFC rather than that of the UK controlling party. This will be subject to transitional arrangements for companies using the existing temporary exempt period at Part 3A of Schedule 25 Income and Corporation Taxes Act 1988 and to specific provisions which will align the commencement of the new CFC rules and the new life insurance regime. The current CFC rules will continue to apply in respect of CFCs with accounting periods that begin before 1 January 2013.
The new CFC regime introduces a gateway for UK companies to consider whether the profits of their CFCs fall within the scope of the new rules. The regime also introduces partial and full exemption for certain qualifying non-trading finance profits earned by a CFC and there are a variety of entity based exemptions from the legislation.
It will continue to be necessary to complete the supplementary pages if at any time in an accounting period a UK company held a relevant interest of 25 per cent or more in a foreign company which is controlled from the UK, even if no profits are apportioned to that company. However, no CFC needs to be included on the supplementary pages where it satisfies either the Tax Exemption or the Excluded Territories Exemption.
The amount of any CFC charges arising on apportionments to UK corporates holding relevant interest of 25 per cent or more in CFCs should be included in the total carried forward of tax chargeable at column J of the supplementary page CT600B and transferred to Box 81 on the main CT600 Company Tax Return form.
The Patent Box will allow companies to elect to apply a reduced rate of Corporation Tax to all profits attributable to qualifying patents and other qualifying intellectual property from 1 April 2013. Legislation will be published as part of Finance Bill 2012.
There will be transitional rules for accounting periods that begin before and end after 1 April 2013. The period falling before 1 April 2013 and the period falling on or after that date are treated as separate accounting periods for calculating the patent box benefits. Income or gains arising in that period are to be apportioned on a just and reasonable basis.
Full benefits of the regime will be phased in over the first four financial years following commencement on 1 April 2013.
The main CT600 Company Tax Return form does not need to be updated as Patent Box profits will form part of a company’s Corporation Tax calculation but HMRC will be updating the CT600 Guide. Further guidance will be made available later in the year.
Following consultation in November 2010 and June 2011, the Government announced improvements to R&D Relief in Finance Bill 2012.
In particular, for the small or medium enterprise (SME) scheme only:
For the SME and large company schemes:
The CT600 Guide will be updated to reflect these changes.
The Finance Bill (Budget 2011/Budget 2012) announced that the rate of tax relief available for decommissioning expenditure for supplementary charge purposes is to be restricted to 20 per cent. To achieve this profits liable to the supplementary charge are to be increased where decommissioning expenditure is taken into account in reducing or eliminating those profits. In addition where decommissioning expenditure reduces the amount of Petroleum Revenue Tax (PRT) chargeable, the Finance Bill also provides a reduction from profits liable to the supplementary charge where the profits resulting from the reduction in PRT would be subject to supplementary charge at a rate of more than 20 per cent.
Companies will need to record any decommissioning adjustments on the CT600I supplementary page of the CT600 Company Tax Return form. Adjustments to increase profits liable to supplementary charge should be entered in Box I2 and/or I3 of the return. Any adjustment relating to the PRT aspect that reduces profits liable to supplementary charge should be entered in Box I6. The CT600 Guide is being updated to reflect these changes.
Accurate facsimiles of the official Company Tax Return forms (based on the final paper format) can be accepted in accordance with Statement of Practice SP5/87. The design of substitute returns and supplementary pages must be centrally approved by HMRC before they are marketed or brought into use.
