Moving a rental portfolio into a limited company is a disposal for Capital Gains Tax purposes. Section 162 of the Taxation of Chargeable Gains Act 1992 can defer some or all of the gain, but only when every statutory condition is met. For transfers from 6 April 2026, the landlord must also submit a valid claim, so relief is no longer automatic.
The biggest risk is assuming that receiving rent automatically proves the existence of a qualifying business. The landlord must demonstrate both a genuine business and its transfer as an operating going concern.
What Is Section 162 Relief?
Incorporation relief rolls the eligible gain into the shares issued by the company. The deferred gain reduces the base cost of those shares and may become taxable when they are sold. It is therefore a deferral, not a permanent exemption.
Without relief, a transfer to a company controlled by the landlord is normally calculated at market value for Capital Gains Tax.
Do You Qualify?
Every condition below must be satisfied:
- The landlord or property partnership carries on a business.
- The business transfers to a company as a going concern.
- All business assets transfer.
- The company issues shares to the transferor as all or part of the consideration.
- For a transfer on or after 6 April 2026, the transferor makes a valid claim on time.
Failure on one condition can leave an immediate Capital Gains Tax liability.
Is Letting a Business?
Section 162 does not define business. HMRC considers whether the activity is seriously and continuously pursued, has substance, follows recognised business principles and is undertaken with a view to profit. The answer depends on the facts.
In Ramsay v HMRC, the Upper Tribunal accepted that residential letting could qualify where the landlord’s overall involvement went beyond passive investment. HMRC says it should accept business status where an individual personally spends at least 20 hours each week on activities indicative of a business. This is an acceptance benchmark, not a statutory minimum, and cases involving fewer hours still require individual assessment.
Helpful evidence includes:
- Contemporaneous records of time spent managing tenants, inspections, compliance, rent collection, property repairs and improvements, and dealing with contractors
- Business bank statements, bookkeeping, accounts, budgets and written procedures
- Tenancy files, correspondence, invoices, insurance documents and maintenance schedules
- Records of regular decisions, active risk management and sustained personal involvement
Portfolio size alone does not determine eligibility. A smaller portfolio may qualify where the activity is substantial, while a large but passively managed portfolio may not. Heavy reliance on managing agents can weaken evidence of personal involvement.
The Going Concern Test
The company must receive an active business that can continue without interruption. Moving legal titles alone is insufficient. The transfer should cover the rental operation, tenant relationships, records, relevant contracts, rights, obligations and management arrangements needed for continued operation.
All business assets apart from cash must normally transfer. Retaining a property or another material asset may break this condition unless the facts show genuinely separate businesses.
How Is Relief Calculated?
Full deferral is generally possible where a qualifying business is transferred wholly for newly issued shares and the amount is not limited by the shares’ cost. If consideration includes cash or a director’s loan account, only the share related proportion of the net gain is deferred. The remaining gain is immediately chargeable.
Qualifying business liabilities assumed by the company may be ignored as other consideration under Extra Statutory Concession D32. However, debt still affects the net value and base cost of the shares, potentially restricting relief when liabilities are close to asset values.
Claiming From April 2026
A claim for a transfer on or after 6 April 2026 must identify the relevant disposals and relief amount. HMRC also requires details of the business, company, issued shares, asset values, other consideration, relief calculation and resulting share base cost.
The deadline is the first anniversary of 31 January following the tax year of transfer. A transfer in 2026 to 2027 therefore has a deadline of 31 January 2029. A required UK residential property Capital Gains Tax return may still be due within 60 days, particularly where relief is partial.
Other Tax Costs
Section 162 deals only with Capital Gains Tax. In England and Northern Ireland, a connected company acquisition can create Stamp Duty Land Tax based on market value, and residential company purchases usually attract higher rates. Wales applies Land Transaction Tax and Scotland applies Land and Buildings Transaction Tax.
Partnership rules may reduce land tax in limited cases, but joint ownership is not automatically a partnership. A partnership created without commercial substance can be challenged.
Before incorporating, model the deferred gain, land tax, refinancing costs, company tax, profit extraction and compliance costs. Existing lenders may require consent, repayment or a new company mortgage.
Common Mistakes
- Treating rental income as sufficient proof of a business
- Moving properties without transferring an operating going concern
- Retaining a business asset without testing the whole asset requirement
- Using a director’s loan account without considering restricted relief
- Ignoring land transaction taxes and refinancing costs
- Missing the claim deadline or keeping inadequate valuation evidence

Frequently Asked Questions
Is 20 hours a week mandatory?
No. It is HMRC’s acceptance benchmark, not a legal threshold. Fewer hours may qualify when the overall activity proves a genuine business, but stronger evidence is likely to be needed.
Can one property qualify?
Potentially. Ramsay involved one building divided into flats, and the decision focused on the degree of activity rather than a fixed property count. Every case depends on its facts.
Does Section 162 remove Stamp Duty Land Tax?
No. It is a Capital Gains Tax relief. Land transaction taxes need a separate analysis, and a connected company transfer may be assessed at market value.
