Business rates: the basics

How business rates are calculated

Your rate bill is made up of a number of parts including the regional rate, the district rate and Net Annual Value (NAV). Your rate bill is calculated by multiplying the NAV of your property by the non-domestic rate poundage (non-domestic regional rate + non-domestic district rate) for your council area for the relevant year (as shown below):

Regional and district rates

The regional rate is set annually by the Northern Ireland Executive and is applied to each district council area in Northern Ireland. The district rate is set annually by each district council in Northern Ireland.

Net Annual Value

Rates for non-domestic or business properties are assessed on their rental value, also known as the Net Annual Value (NAV). NAV is an assessment of the annual rental value that your property could reasonably be expected to be let for if it was on the open market. Each non-domestic property is valued in line with comparable properties in the vicinity.

The current valuation list for non-domestic properties came into operation on 1 April 2015 and is based on rental values as at 1 April 2013.
