For UK landlords looking to transfer their property portfolio into a limited company, one of the most significant tax considerations is Capital Gains Tax (CGT). Section 162 Incorporation Relief offers a powerful mechanism to defer this liability, allowing property business owners to restructure without an immediate CGT charge. This guide explains how the relief works, who qualifies, how it is calculated, and what has changed since April 2026.
What Is Incorporation Relief?
Incorporation Relief, governed by Section 162 of the Taxation of Chargeable Gains Act 1992 (TCGA 1992), allows an individual or partnership to transfer a qualifying business into a limited company without triggering an immediate CGT liability. Instead of paying CGT at the point of transfer, the gain is deferred and rolled into the base cost of the shares received in the new company. This means CGT only becomes payable when those shares are eventually sold.
The relief is particularly relevant for landlords who have accumulated significant gains on their property portfolios and are considering incorporating, for example, to take advantage of lower corporation tax rates or to remove the restriction on mortgage interest relief introduced by Section 24 of the Finance (No. 2) Act 2015.
How Does the Relief Work?
When a property business is transferred to a limited company wholly in exchange for shares, the chargeable gain that would normally arise on that disposal is deferred. The deferred gain is then subtracted from the base cost of the shares issued by the company. This means that if the shares are sold in the future, a higher gain may arise at that point.
The formula used to calculate the relief is:
Incorporation Relief = Total Gain x (Value of Shares Received / Total Consideration)
Full relief is available when the entire consideration is received as shares. Where the consideration is a mix of shares and cash (including credits to a director’s loan account, which HMRC treats as cash), only partial relief applies, and CGT becomes immediately payable on the cash element.
Worked Example
Sarah transfers her property business to a limited company and receives 1,000 shares with a market value of £150 each. The total company value is £150,000 and the agreed chargeable gain on the transferred assets is £90,000.
| Calculation | Amount |
|---|---|
| Incorporation Relief = £90,000 x (£150,000 / £150,000) | £90,000 |
| Base cost of shares = £150,000 minus £90,000 | £60,000 |
Sarah defers the full £90,000 gain. When she eventually sells her shares, a CGT charge will arise based on the reduced base cost of £60,000.
Key Conditions for Claiming the Relief
To qualify for Incorporation Relief, four conditions must be satisfied:
1. You must be an individual or partnership (not a company)
The transfer must be made by a sole trader or business partnership, not by a corporate entity.
2. You must transfer the business as a going concern
The entire business must be transferred. You cannot cherry-pick individual properties. Retaining even one property from the portfolio will disqualify the entire transfer from relief.
3. All business assets except cash must be transferred
Cash can be retained, but all other assets of the business must be included in the transfer.
4. Consideration must be wholly or partly in shares
The company must issue shares to the transferor as part or all of the consideration. Any cash element, including credits to a director’s loan account, restricts the available relief proportionately.
The Business Test: The Most Critical Hurdle
The most challenging aspect of qualifying for Incorporation Relief is demonstrating that the property activities constitute a “business” rather than a passive investment. HMRC has historically resisted treating property letting as a business for this purpose, and there is no statutory definition of “business” in the legislation.
The landmark case Ramsay v HMRC established the key precedent in this area. Elizabeth Ramsay managed a portfolio of flats, spending approximately 20 hours per week on activities including meeting tenants, managing utility bills, maintaining communal areas, and handling repairs. The Upper Tribunal ruled her activities constituted a business for incorporation relief purposes.[^5][^6]
Following the Ramsay judgment, HMRC updated its guidance at CG65715 to accept that incorporation relief will be available where an individual spends 20 hours or more per week personally undertaking business-type activities. However, this is not a rigid threshold; HMRC acknowledges that a business may exist in other circumstances too, and each case is judged on its individual facts.
Activities that support the business test include:
- Personally collecting rent and chasing arrears
- Meeting tenants to address issues and arrange repairs
- Liaising with contractors and managing maintenance directly
- Vetting tenants and managing void periods
- Managing utilities and communal areas
Outsourcing all management functions to a letting agent significantly weakens the business test argument, as it may be viewed as too passive to constitute more than a simple investment.
Stamp Duty Land Tax: A Separate Consideration
It is important to understand that Incorporation Relief addresses CGT only. SDLT remains payable on the market value of properties transferred to the company at standard residential rates, unless the transfer qualifies for separate SDLT partnership relief under Schedule 15 of the Finance Act 2003.
To access SDLT partnership relief, the property business must genuinely operate as a partnership, with two or more individuals carrying on a business together with sufficient active involvement. HMRC has anti-avoidance rules targeting artificial partnership arrangements created purely for tax purposes, and it is generally recommended that a partnership exists for at least three years before incorporation to demonstrate genuine commercial substance.
Where both Incorporation Relief and SDLT partnership relief are available, the combined tax saving can be substantial. These two reliefs operate independently and have separate qualifying conditions.
What Changed From 6 April 2026?
A significant procedural change took effect on 6 April 2026. Prior to this date, Incorporation Relief applied automatically provided the qualifying conditions were met, with no formal claim required. From 6 April 2026, taxpayers must actively claim the relief in their Self-Assessment tax return for the tax year in which the business transfer takes place.
The claim must include:
- Full details of the transaction
- A description of the nature of the business transferred
- Supporting tax calculations
Where no claim is made, HMRC may treat the transfer as a disposal at market value, resulting in an immediate CGT charge. This change is administrative rather than substantive, meaning the relief itself and its underlying qualifying conditions remain unchanged. However, the compliance burden has increased, and the risk of missing the relief through an incorrect or incomplete return is now very real.
Can You Opt Out of Incorporation Relief?
Yes. Section 162A TCGA 1992 allows taxpayers to elect not to apply incorporation relief. A landlord might choose this if they wish to use Business Asset Disposal Relief (formerly Entrepreneurs’ Relief) to pay CGT at a lower rate, or if they want to maximise the value of a director’s loan account. The election must be made in writing to HMRC within strict time limits based on when the shares are disposed of.

Frequently Asked Questions:
Does my property portfolio qualify as a business?
HMRC treats this as a question of fact. Active involvement in managing your portfolio is essential. Spending 20 or more hours per week on management activities is a strong indicator, following the Ramsay v HMRC ruling, but smaller portfolios may still qualify with sufficient evidence of active management.
Do I need to transfer every property in my portfolio?
Yes. Section 162 requires the transfer of the whole business as a going concern. Retaining even one property from the portfolio disqualifies the entire transfer from relief.
Will I still pay Stamp Duty when I incorporate?
Yes, unless your transfer qualifies for SDLT partnership relief under Schedule 15 Finance Act 2003. Incorporation Relief covers CGT only; SDLT is a separate consideration.
What changed with incorporation relief from April 2026?
From 6 April 2026, you must actively claim Incorporation Relief in your Self-Assessment tax return. It no longer applies automatically. The claim must include transaction details, a business description, and supporting tax calculations. Failing to claim means HMRC can treat the transfer as a taxable disposal at market value.
Can I opt out of Incorporation Relief?
Yes. Section 162A allows you to elect out in writing to HMRC within specified deadlines. You might do this to use Business Asset Disposal Relief or to maximise the value of a director’s loan account instead.
Is a director’s loan account treated as cash consideration?
Yes. HMRC treats credits to a director’s loan account as cash consideration, which restricts the amount of Incorporation Relief available. Only gains relating to the share element of the consideration can be fully deferred.
