Hospitality, tourism, leisure and childcare businesses in NI will not have to pay rates this year, Finance Minister Conor Murphy has announced.
Most retailers, aside from larger supermarkets and off licences, will also be exempt for the whole year.
Businesses in other sectors will have their current three month exemption extended by another month.
Rates are the property taxes paid by businesses and are a significant expense in retail and hospitality.
At the start of the coronavirus crisis Mr Murphy gave all businesses a three month rates exemption.
