Investment Zones were announced in the UK in the 2023 Spring Budget, with the aim of boosting growth in key sectors. These zones typically cover a defined economic area.Ìý
Businesses located within an Investment Zone may be eligible to claim a range of tax reliefs, including enhanced capital allowances for expenditure on plant and machinery, enhanced structures and buildings allowance and relief from employer National Insurance contributions (NICs) for new employees.ÌýÂ
Relief from Stamp Duty Land Tax (SDLT) is available for certain acquisitions of land and buildings in Investment Zones in England. There is a similar relief for Land and Buildings Transaction Tax (LBTT) in Scottish Investment Zones and Land Transaction Tax (LTT) for Investment Zones in Wales.Ìý
In addition, the local authorities hosting the Investment Zone tax sites will offer discretionary relief on business rates, or non-domestic rates, to further reduce the cost of businesses locating within the site.Ìý
Investment Zones special tax sitesÂ
Tax reliefs are not available to everyone who operates in an Investment Zone. As well as being within the boundary of an Investment Zone, you must operate in a specially designated area within an Investment Zone. In addition, you must meet certain specific criteria.Ìý
These areas are called Investment Zone special tax sites. Investment Zone special tax sites need to meet certain criteria, demonstrating that the sites are underdeveloped as the tax reliefs are designed to encourage new activity and land development.Ìý
You can find maps of Investment Zones and Investment Zone tax sites on °Ç¸ç³Ô¹Ï.Ìý
The tax reliefs are only available if your business is located in a designated Investment Zone special tax site. You cannot claim tax reliefs until the relevant Investment Zone special tax site has been designated. Not all Investment Zones will include special tax sites.
