Commercial Rates

Commercial Rates

Rates are payable on commercial/industrial properties that have been valued for rating purposes.  Rateable valuations are determined by the Commissioner of Valuation, not by the Local Authority.

Approximately twenty percent of Mayo County Council's revenue expenditure is raised through commercial rates.  The collection of rates on commercial and industrial properties is essential in maintaining the full range of council services.

Annual Rate on Valuation

The ARV is the figure that is used to calculate the annual rates payable by the occupier of a rateable property taking the valuation of the premises into account.  It is fixed by the elected members of the Council at the Annual Budget meeting each year.  The ARV for the year 2017 is €68.76. See note below.

For example if your property is valued at €15.00, then €15.00 x 68.76 = €1,031.40. This is the amount of rates due for 2017.

Section 32 - Transfer of Rateable Property

New duty on owners/ratepayers in relation to a transfer of property

Main provisions of Section 32 of the Act

  • It places an obligation on property owners, or their agents, to notify the Local Authority where an interest in a rateable property is transferred and the person liable for rates changes.
  • The person transferring the property, either the owner or occupier, must dischargeall rates for which he/she is liable at the date of transfer.

Failure to notify Mayo County Council of a change in interest within 14 days of the transfer date, may result in a penalty for non-compliance in that, the owner becomes liable for an amount which is equivalent to the level of outstanding liabilities (up to a maximum of 2 years liability).

Revision of Valuations

Requests for revision of valuation are normally instigated by the Local Authority, but any owner or occupier of a rateable property can apply for revision directly to the Valuation Office, provided that there has been a material change in the property since it was previously valued.

In general, Mayo County Council will automatically list for valuation, new properties or those where significant alterations have taken place.  Any person who is an interest holder in a property to which the Valuation Act 2001 refers, may, on payment of the prescribed fee, apply for a revision of valuation to the Commissioner of Valuation.

The rateable valuation is used by the Local Authority to determine the commercial rates payable by each ratepayer.

The Valuation Act, 2001 defines what properties are relevant for rating purposes.  See attached links for further information. Rateable Property (Word, 26KB).  Exempt Property (Word, 27KB).
