Incorporation Relief & SDLT on Partnership Incorporation
Incorporating an existing sole trade or partnership can deliver commercial, liability and succession planning advantages. However, transferring a business, particularly one that holds property, into a company has significant tax consequences.
Two areas require careful technical analysis:
- Incorporation relief for capital gains purposes
- SDLT treatment where partnership property is transferred to a company
Errors in structuring can trigger immediate tax charges or deny relief entirely. Proper sequencing, documentation and compliance are essential.
At Jonathan Lea Network, we advise partnerships and professional practices on structuring incorporation efficiently and defensibly.
Incorporation Relief: Deferring Capital Gains
Where a business is transferred to a company in exchange for shares, incorporation relief may allow capital gains arising on the transfer of business assets to be deferred.
Broadly, relief may apply where:
- A business is transferred as a going concern
- All business assets (other than cash) are transferred
- Consideration is wholly or partly in shares
The deferred gain is effectively rolled into the base cost of the shares received.
However, technical conditions must be satisfied. Common issues include:
- Whether the activity constitutes a “business” for tax purposes
- Treatment of goodwill
- Mixed consideration (cash plus shares)
- Partial transfers
- Subsequent share disposals
For transfers on or after 6 April 2026, incorporation relief will no longer apply automatically where statutory conditions are met. A formal claim will be required in the transferor’s Self Assessment return for the year of transfer. Failure to make a valid claim may result in immediate capital gains crystallising.
Incorporation relief is subject to detailed statutory provisions and anti-avoidance rules. Legislative interpretation and HMRC practice can evolve, so up-to-date analysis and careful compliance are critical before implementation.
SDLT on Incorporation of Partnerships
Where a partnership holds land or property, transferring that property to a company can trigger SDLT.
The SDLT position depends on:
- The identity and proportions of partners
- Shareholdings in the new company
- Application of the partnership SDLT rules
- Connected party provisions
- Market value substitution rules
The SDLT partnership code is highly technical and frequently misunderstood. In some cases, relief may be available; in others, a significant SDLT charge can arise even where the economic ownership appears unchanged.
Detailed modelling of partnership shares and corporate ownership is essential before proceeding.
Property-Rich Professional Practices
Incorporation frequently arises in:
- Property investment partnerships
- Farming businesses
- Professional practices
- Family-owned trading partnerships
Where land represents a substantial proportion of business value, SDLT exposure can materially affect viability of incorporation.
In some cases, alternative sequencing or pre-incorporation restructuring may improve outcomes, but anti-avoidance provisions must be considered carefully.
Interaction Between CGT and SDLT
Capital gains and SDLT consequences must be analysed together.
For example:
- A structure that preserves incorporation relief may still create SDLT exposure
- A transfer structured to mitigate SDLT may affect CGT treatment
- Mixed consideration can affect both regimes
Integrated advice is therefore essential to avoid solving one issue while creating another.
Anti-Avoidance and Commercial Rationale
Both incorporation relief and the SDLT partnership rules contain anti-avoidance provisions.
Relief may be denied or SDLT charged on a market value basis where arrangements are considered tax-driven or where statutory conditions are not strictly met. Even where there is a genuine commercial rationale — such as limited liability, succession planning or financing requirements — relief can be lost if the structure is not implemented carefully.
Clear documentation of commercial drivers, disciplined implementation and correct claims compliance are critical to managing challenge risk.
Post-Incorporation Considerations
After incorporation, additional issues may arise, including:
- Extraction of profits
- Shareholder agreements
- Future share disposals
- De-grouping charges (if property is later transferred)
- Ongoing compliance with ERS or other regimes
The incorporation event should be aligned with longer-term planning rather than treated as an isolated transaction.

Incorporating with Certainty
Incorporation can be a strategic step in the evolution of a business. However, where property is involved, the tax consequences are complex and potentially significant — and, from April 2026, incorporation relief will require an active claim rather than operating automatically. With careful planning and technically rigorous execution, it is possible to manage capital gains exposure and structure SDLT efficiently. If you are considering incorporating a partnership or property-holding business, early specialist advice can materially affect both risk and outcome.
Incorporating with Technical Certainty
Transferring a partnership or sole trade to a company is rarely tax-neutral, particularly where property is involved. Incorporation relief and the SDLT partnership rules operate independently, and structuring that addresses one regime may expose the other.
From April 2026, incorporation relief will require an active claim, increasing the importance of procedural discipline alongside technical eligibility.

FAQ: Incorporation Relief & SDLT on Partnership Incorporation
Relief may be denied if the exchange forms part of arrangements where tax avoidance is a main purpose, or if consideration includes non-qualifying elements. In addition, evolving anti-avoidance provisions and interpretative shifts can affect eligibility. Clearance is often prudent where a subsequent disposal is anticipated. Where assets are transferred intra-group on a no gain/no loss basis and the transferee leaves the group within the relevant period, a de-grouping charge may crystallise. This risk is frequently overlooked in pre-sale restructurings and must be modelled before implementation. Yes. A capital reduction or reorganisation may be tax-efficient but ineffective if it does not produce lawful distributable reserves or if accounting treatment undermines the intended outcome. Legal, tax and accounting analysis must be aligned. Hive-downs intended to create a clean trading subsidiary for disposal must preserve trading status and meet holding period requirements. Improper sequencing can jeopardise exemption eligibility or create unintended gain crystallisation.
Although clearance is not mandatory in every reconstruction or demerger, it is often strategically sensible where anti-avoidance provisions could be engaged or where transaction timing is sensitive. Clearance can materially reduce buyer-side risk perception in a subsequent disposal.
