Electricity Tax
The Finance Act 2008 provided for an excise duty called electricity tax. It applies to supplies of electricity after 1st October 2008. The supplier pays the tax and makes all relevant returns.
The tax is also applicable to a supplier which is situated outside the State. It must make the relevant arrangements with the Revenue for payment and accounting.
There are two different tax rates. The rate applicable to business use is 50 cents per megawatt hour. The rate is €1 cent per megawatt hour for non-business, non-domestic use. Supplies for domestic use are not subject to the tax.

Suppliers must register with the Revenue Large Cases division. The accounting period is annual. Prescribed forms of returns are required, giving particulars of
- unit supplied,
- units for taxable use
- units for business and non-business use,
- details of electricity received from renewable and green sources,
- Â tax payable
Where all the requisite information is not shared available, an estimated return may be made. The supplier must assess at what rate the tax is payable that based on exempt household use and the relevant taxable business use.
The return is made, and the tax is payable by electronic funds transferred. Where a revision of a return is made, there may be an underpayment or overpayment requiring adjustment.
Records must be kept for five to six years and open for inspection. Contravention of the key aspects of the legislation constitutes an offence.

- generated from renewable sources,
- environmentally friendly heat and power generation, code generation
- certain chemical reduction electrolytic or metallurgical processes
- combined heat and power generation
The heat and power co-generation is conditional on approval by the relevant authority that it satisfies EU high-efficiency criteria.

Solid fuel carbon tax applies to solid fuels supplied in the state after 1st May 2013. It applies to coal and peat as defined. The tax applies to peat extracted for  supply in the state. Supplies of fuel for use outside the state are not subject to the tax.
Liability to the tax arises on the first supply of solid fuel by a supplier. The supplier is accountable for the tax and must make payment.
