The Finance Minister has announced an emergency £100 million rates package to assist businesses impacted by COVID-19. Find out more about COVID-19: Emergency rates package for businesses.

Your annual business rate bill is calculated and collected by Land & Property Services.

Non-domestic property in Northern Ireland is assessed on the basis of its rental value known as the Net Annual Value (NAV). The NAV of your business property will determine the amount of rates you will have to pay. Please note that your rateable value (NAV) is not your rate bill.

This guide explains valuation of a new property, valuing alterations to existing properties, specialist schemes that apply to some non-domestic properties and how to appeal your valuation if you think it may be incorrect.

The closure will be kept under regular review and the dates will change in line with further Government announcements. Further information on service updates will be available on the LPS website.
