Taxes Consolidation Act 1997 section 13

Extension of charge to income tax to profits and income derived from activities carried on and employments exercised on the Continental Shelf

Section 13 extends the charge to Irish income tax to cover profits and gains from exploration or exploitation activities carried on in designated areas of the Continental Shelf, as well as dealings in rights arising from such activities, and brings within the tax charge certain emoluments of employees working offshore.

• Profits or gains from exploration or exploitation activities in a designated area of the Continental Shelf are treated as profits from activities carried on in the State for income tax purposes.
• Where a non-resident person earns profits from exploration or exploitation activities or from dealings in exploration or exploitation rights, those profits are treated as arising from a trade carried on through a branch or agency in the State, ensuring they are chargeable to Irish income tax.
• Where exploration or exploitation work is carried out on behalf of a licence or lease holder under the Petroleum and Other Minerals Development Act 1960, the licence or lease holder is deemed to be the agent of the person doing the work for assessment purposes.
• Emoluments of employees performing duties in a designated area in connection with exploration or exploitation activities are treated as emoluments for duties performed in the State, bringing them within the charge to income tax.
