A Land Value Tax for Northern Ireland

Dataset from research analysis performing an impact assessment of a Land Value Tax (LVT) on domestic properties in Northern Ireland.

The report was commissioned by NICVA's Centre for Economic Empowerment and produced by Ronan Lyons and Andy Wightman.

For a detailed impact assessment of a potential land value tax in Northern Ireland, existing information obtained from the domestic valuation roll (containing 776,767 properties) was analysed (list searchable here). This information was used to demonstrate variations in the underlying value of the land. The distributional impact of a revenue neutral land value tax (where total revenue would be equal to the current rates revenue) applied equally to all areas is also calculated using this data.

The analysis in the dataset is broken down by Northern Ireland Small Area. Hedonic regression of house prices, whereby the valuation for similar properties are compared across all Small Areas in Northern Ireland, with the difference being attributed to variation in the underlying land value (i.e. there is a difference between the value of the property as a building, and where it is located). The estimated difference in the current rates bill for the average property is also included. NI Multiple Deprivation Measures are included for the Small Areas, as are geographical coordinates.
