Corporation Tax is charged on all profits (income and gains), wherever arising, of companies resident in the State, with some exceptions, and non-resident companies who trade in the State through a branch or agency.
How is a Company Taxed?
Companies pay Corporation Tax. This tax is charged on the company's profits which include both income and chargeable gains. A company's income for tax purposes is calculated in accordance with Income Tax rules. Chargeable gains are calculated in accordance with Capital Gains Tax rules.
What is the rate of Corporation Tax?
There are two rates of Corporation Tax:
- 12.5% for trading income unless the income is from an excepted trade* in which case the rate is 25%
- 25% for non-trading income (e.g. investment income, rental income)
How do I decide whether to trade as a Sole Trader or as a Company?
Your own individual circumstances will dictate whether you should operate as a limited company or as a sole trader. In addition to the taxation issues you need to consider there are various other practical and legal matters which should be taken into account when setting up a company and on which you should seek professional advice.
What is Corporation Tax charged on?
All profits (income and gains), wherever arising, of the companies.
Basis of Assessment
Corporation Tax is assessed on the profits of a company's accounting period at the relevant Corporation Tax rate in force during the accounting period.
Where the rate of Corporation Tax changes during an accounting period, the profits of that period are apportioned on a time basis and taxed at the appropriate rate for the purpose.
An accounting period for tax purposes is a period of not more than twelve months and is normally the period for which the company makes up its annual accounts.
Company capital gains
Capital gains, other than gains from development land, are included in a company's profits for Corporation Tax purposes and are charged to tax under a formula that means in effect that tax is paid at the prevailing capital gains tax rate.
A company resident in the state is liable to Corporation Tax on its worldwide profits, not just its Irish source profits. Whether or not these profits are brought into Ireland is irrelevant for this purpose.
The term 'residence' was not, until recently, defined in law. The general rule was that companies, whose 'central management and control' was exercised in the State, were treated as resident here. This rule or test emerged as a result of judicial decisions set down in case law. Factors to be taken into account in establishing where the company's central management and control lie include, for example, where the important questions of company policy are determined, where the majority of directors reside, where the negotiation of major contracts is undertaken and where the company's head office is located.
Paying Corporation Tax & Filing Obligations
The Self-Assessment system 'Pay & File' applies to companies. The obligations of a company with regard to paying Corporation Tax and filing its return are as follows:
Compute and pay its preliminary tax liability by the specified date.
Complete and file, on line, a Form CT1 and where applicable a Form 46G
Pay any balance of tax due when lodging the return i.e. within nine months of the end of the accounting period. (The specified return date and payment due date is the 21st day of the applicable month. This date is extended to the 23rd of the applicable month for companies who file their return and pay any associated tax due via Revenue’s Online Service.
Preliminary Corporation Tax
A company is obliged to pay to the Collector General, via ROS, the amount of preliminary tax appropriate to the accounting period.
The total amount of preliminary tax paid must be equal to or greater than 90% of the company's final liability for the accounting period.
Special provision is made for small companies whose liability does not exceed €200,000.
What expenses can a company set against its profits?
- A company is, in general, entitled to deductions in respect of revenue expenditure - wholly and exclusively incurred for the purposes of its trade - against its profits.
- It is not, however, entitled to claim a deduction in respect of business entertainment expenses nor is it entitled to claim a deduction in respect of capital expenditure.
- It may, however, be entitled to capital allowances in respect of certain capital expenditure e.g. wear & tear allowances - see below.
- There is an allowance for wear and tear of plant and machinery in use for the purposes of a trade at the end of an accounting period. The allowance is calculated by reference to the cost of the item (less any grants received) and the allowable expenditure may be written down at the rate of 12.5% on a straight line basis. A wear and tear allowance is also available in respect of expenditure incurred on motor vehicles - also at the rate of 12.5% on a straight line basis.
- Capital allowances are also available in respect of expenditure on transmission capacity rights, computer software, energy efficient equipment including electric and alternative fuel vehicles, and industrial buildings and specified intangible assets. The rate at which the expenditure may be written down varies according to the type of expenditure incurred.
- It should be noted that depreciation of capital assets as computed for audited accounts purposes is not an allowable expense against the company's income for the purposes of Corporation Tax.
What about pre-trading expenditure?
Expenditure which is wholly and exclusively laid out for the purposes of a company's trade or profession in a three year period before commencement is allowed as a deduction in calculating the profits of the company following commencement.
|Standard Rate on Trading Income||12.5% from 1 January 2003|
Finance Bill 2014 will amend Ireland's company tax residence rules to provide that all companies that are incorporated in Ireland will be tax resident here, unless regarded as resident in a territory other than the State for the purposes of a tax treaty. The change will come into effect for new companies from 1 January 2015 while a transition period will apply until the end of 2020 for existing companies. This change will bring Ireland's rules into line with the rest of the OECD.
The current regime for intangible assets provides capital allowances for expenditure incurred on the provision of certain intangible assets for use in an Irish trade. This measure is being enhanced:
- The use of such allowances in any accounting period is currently restricted to a maximum of 80% of the income from the relevant trade in which the acquired assets are used with any excess carried forward for offset against trading income in subsequent accounting periods. Any related interest expense deduction which may be allowed for borrowings
incurred on such an acquisition is similarly restricted. This restriction on aggregate allowances (and related interest) will be removed.
- The definition of 'specified intangible asset' contained in this provision will also be amended to include customer lists.
Further details will follow in the Finance Bill.
Accelerated Capital Allowances for Energy-efficient Equipment
This is a measure to incentivise companies to invest in energy-efficient equipment. It allows them to deduct 100% of capital expenditure incurred on eligible equipment (that meets specified energy-efficiency criteria) from trading profits in the year of purchase rather than over the usual 8 year period for plant and machinery. This measure was due to expire at the end of 2014 and following a review by the Department of Communications, Energy and Natural Resources is being extended to the end of 2017.
Payment - Small Companies
With effect from 6 December 2007 a small company is a company with a corporation tax liability of less than €200,000 in the preceding year. Preliminary tax of at least 90% of the liability for the period or 100% of previous year's liability is due one month (by the 21st day of that month) before the end of the accounting period. New or start up companies with a Corporation Tax liability of less than €200,000 in their first accounting period will not be required to pay Preliminary Corporation tax. The liability is paid when the return is filed.
Payment - Other Companies
- Finance (No.2) Act 2008 provides for revised arrangements for the payment of preliminary tax by large companies with a tax liability of more than €200,000 (in their previous accounting period).
- The new arrangements provides for payment of preliminary tax by large companies in two instalments.
- The first instalment will be payable in the 6th month of the accounting period (i.e. 21st/23rd June for a company with calendar year accounts) and the amount payable will be 50% of the corporation tax liability for the preceding accounting period or 45% of the corporation tax liability for the current accounting period.
- The second instalment will be payable (as before) in the 11th month of the accounting period i.e. 21st/23rd November for a company with calendar year accounts) and the amount payable will bring the total preliminary tax paid to 90% of the corporation tax liability for the current accounting period.
- The revised arrangements apply generally where the accounting period is more than 7 months in length (for shorter accounting periods, preliminary tax of 90% of tax liability is payable in one instalment as before)
Start-Up Companies - 3 Year Tax Exemption
The scheme which provides relief from corporation tax on the trading income and certain gains of new start-up companies in the This scheme provides relief from corporation tax on trading income (and certain capital gains) for new start-up companies in the first 3 years of trading.
This scheme is being enhanced to allow any unused relief arising in the first 3 years of trading due to insufficiency of profits to be carried forward for use in subsequent years. This is subject to the maximum amount of relief in any one year not exceeding the eligible amount of Employers' PRSI in that year.
Research and Development (R & D) Tax Credit
The R&D Tax Credit regime provides for a 25% tax credit for incremental expenditure on certain research and development (R&D) activities over such expenditure in a base year (2003). Finance Act 2012 provided that the first €100,000 of qualifying R&D expenditure would benefit from the tax credit without reference to the 2003 threshold. The amount of expenditure so allowed on a volume basis was increased to €200,000 in Finance Act 2013 and is now being increased again to €300,000.
The limit on the amount of qualifying research and development expenditure that can be outsourced to another company is also being increased from 10% to 15%.
