Residential property developer tax is a 4% surcharge on top of corporation tax, charged on residential development profits above an annual allowance of £25 million. It has applied to accounting periods beginning on or after 1 April 2022. The allowance sounds generous until you see how it is divided in a group that has not nominated an allocating company.
The charge
Section 33 of the Finance Act 2022 imposes the tax at "4% of the residential property developer profits for an accounting period". Section 51 sets commencement at accounting periods beginning on or after 1 April 2022.
The base is not gains and it is not turnover. Under section 38, RPD profits are computed from the developer's adjusted trading profits, adjusted for joint venture profits and reduced by the allowance and by reliefs. That single word — trading — determines most scope questions.
Who is an RP developer
Section 34 defines an RP developer as a company that either carries on residential property development activities, or has a substantial interest in a relevant joint venture company. The joint venture limb matters: a minority investor in a development JV can be within the charge without carrying out any development itself.
Section 35 defines the activities, and the breadth is the point. They are activities carried on by a company on UK land in which it has an interest, for the purposes of or in connection with the development of residential property, and they expressly include:
- Dealing in residential property;
- Designing it;
- Seeking planning permission in relation to it;
- Constructing or adapting it;
- Marketing it;
- Managing it, and any activities ancillary to these.
Note that seeking planning permission is on the list. A company whose only activity in a period is promoting a site through planning is carrying on an RPD activity.
What is outside the charge
Three exclusions do the heavy lifting, and they work in different ways.
Non-profit housing companies are exempted outright by section 34 — non-profit registered providers of social housing, registered social landlords in Wales and Scotland, and registered housing associations in Northern Ireland.
Certain buildings are not residential property at all under section 37. The list covers student accommodation where the use condition is met — occupation by persons on at least 165 days a year — children's homes, care facilities for elderly or disabled persons, armed forces accommodation, emergency services housing, hospitals and hospices, prisons, hotels and inns, and religious institutions.
Investment property falls outside the base. This is the exclusion most often described wrongly. There is no statutory carve-out labelled "build to rent". What there is, in section 38, is a base built on adjusted trading profits. Property developed and held as an investment rather than as trading stock does not produce trading profits, so it does not produce RPD profits. The consequence is the same, but the reasoning matters — because it means the classification of the asset in your accounts is doing the work, and a change in intention can change the answer.
The allowance trap
Section 43 gives an allowance of £25,000,000 for a 12-month accounting period, reduced pro rata for shorter periods. For a standalone developer that is straightforward.
For a group it is not. A group may nominate an allocating member company, which allocates the allowance among the group's RP developers through an allowance allocation statement specifying how much has been allocated to each member for each period.
If no allocating member is nominated, the default in section 43(5) applies: each RP developer's allowance is £25,000,000 divided by the number of companies within the charge to corporation tax that are members of the group.
Read that again, because it is not divided among the developers — it is divided among all group companies within the charge to corporation tax. A group with one developer and nine dormant or non-developing subsidiaries that all sit within the charge is looking at an allowance of £2.5 million rather than £25 million, purely for want of a nomination. This is an administrative failure that converts directly into tax.
What to do about it
Four practical steps cover most of the exposure.
Count the group. Establish how many companies are within the charge to corporation tax, and nominate an allocating member. This is the single highest-value action available and it costs nothing.
Classify the land deliberately. Trading stock or investment is a real accounting judgement with a direct tax consequence here. Document the intention at acquisition, and revisit it if the plan changes.
Check the joint ventures. A substantial interest in a relevant JV company brings you into the regime. Interests taken for commercial reasons, in vehicles you do not control, need to be in the computation.
Test the building exclusions properly. Student accommodation only escapes if the use condition is met. Assuming a purpose-built scheme qualifies without checking the 165-day test is a common shortcut.
