Details of how the Stormont Executive intends to raise more revenue could be included in a fiscal sustainability plan which is expected to be published by the finance minister on Thursday.

The plan was a condition of the £3bn financial support package from the UK government which accompanied the return of devolution.

It is intended to explain how the executive will run balanced budgets in future.

That includes examining options for efficiencies, revenue generation and borrowing powers.

The executive has committed to raising £113m of additional revenue by the start of the 2025 financial year, though that is expected to be largely covered by the normal annual increase in rates.

Her department has published responses to a rates consultation which was started by the government while devolution was suspended.

The consultation included a proposal to increase rates for the most valuable houses.

Rates are based on property values and the rateable value of houses is currently capped.

No houses are assumed to be worth more than £400,000 at a 2005 valuation.

That means that large homes in more affluent areas of north Down, for example, currently pay the same rates as much more modest detached houses.
