Should Landlords Incorporate Their Property Portfolio?

The idea of moving rental properties into a limited company has become increasingly popular among landlords.

A company may receive more favourable tax treatment for mortgage interest and can allow rental profits to be retained for future investment. However, incorporation is not simply an administrative change.

The landlord is transferring property from one legal owner to another. This can create Capital Gains Tax, Stamp Duty Land Tax, refinancing costs, legal fees and additional compliance obligations.

The right decision depends on the portfolio, borrowing, future investment plans and how much income the landlord needs to withdraw personally.

What does incorporating a property portfolio mean?

Incorporating a property portfolio usually means transferring personally owned rental properties to a limited company.

After the transfer:

• The company becomes the property owner
• The company receives the rent
• The company becomes responsible for property expenses
• The company normally needs its own mortgages
• The company pays Corporation Tax on its profits and chargeable gains
• The landlord becomes a shareholder and usually a director
• Money withdrawn from the company must follow the relevant salary, dividend, loan or capital rules

This is different from simply setting up a company and using it to purchase the next property.

Transferring an existing portfolio can create significant immediate tax and finance costs. Purchasing future properties through a company does not involve transferring the existing properties.

Why do landlords consider incorporation?

The main reasons usually include:

• The treatment of residential mortgage interest
• Lower initial tax rates on profits retained in the company
• Reinvesting profits without withdrawing them personally
• Bringing family members into the ownership structure
• Succession and estate planning
• Creating a separate entity for future property purchases
• Building a larger portfolio over the long term

These advantages must be compared with the transfer costs and the tax payable when company funds are eventually withdrawn.

Personally owned rental property

An individual landlord pays Income Tax on their taxable rental profit.

For the 2026/27 tax year, property income is generally taxed at the individual’s applicable Income Tax rates. For taxpayers in England, Wales and Northern Ireland, these are currently:

• Basic rate: 20%
• Higher rate: 40%
• Additional rate: 45%

Different Income Tax bands apply to Scottish taxpayers.

From 6 April 2027, separate property income tax rates are due to apply. The legislated rates for 2027/28 are:

• Property basic rate: 22%
• Property higher rate: 42%
• Property additional rate: 47%

The impact of devolved tax arrangements should be reviewed where relevant. Further details are available in the government’s property income rate guidance.

Residential mortgage interest for individual landlords

Individual landlords cannot normally deduct residential mortgage interest directly from rental income when calculating taxable profit.

Instead, qualifying finance costs are generally used to calculate a basic rate tax reduction.

This can create a higher taxable profit than the landlord’s actual cash surplus. It can also:

• Push a landlord into a higher tax band
• Reduce their Personal Allowance
• Affect the High Income Child Benefit Charge
• Increase payments on account
• Create tax when the property has produced limited cash
• Restrict how quickly finance cost relief can be used

HMRC explains the current restriction in its residential landlord finance cost guidance.

From 2027/28, the residential finance cost reduction is expected to use the new 22% property basic rate.

How is a property company taxed?

A limited company pays Corporation Tax on its taxable profits.

The current Corporation Tax framework includes:

• A 19% small profits rate for qualifying companies with profits of £50,000 or less
• A 25% main rate for profits above £250,000
• Marginal Relief for qualifying profits between £50,000 and £250,000

These thresholds can be reduced where the company has associated companies or a short accounting period. This means a landlord with several companies cannot assume that each company receives the full thresholds.

Current rates are available in HMRC’s Corporation Tax guidance.

Can a company deduct mortgage interest?

A property company is not subject to the same residential finance cost restriction as an individual landlord.

Interest and other finance costs are generally dealt with under the Corporation Tax loan relationship rules. Qualifying interest may therefore be deductible when calculating the company’s taxable profits, subject to the relevant conditions and restrictions.

This can make company ownership attractive for landlords with:

• Substantial mortgages
• Higher personal tax rates
• Significant plans for further investment
• No immediate need to withdraw all rental profits

However, a tax deduction does not make the mortgage itself cheaper. Company borrowing may carry higher rates, larger arrangement fees or stricter lending conditions.

The company tax rate is only the first layer

A common mistake is to compare a personal Income Tax rate of 40% or 45% with a Corporation Tax rate of 19% or 25% and conclude that incorporation automatically saves tax.

The company and its shareholders are separate taxpayers.

After the company pays Corporation Tax, the shareholder may face additional tax when profits are withdrawn.

Money might be extracted as:

• Salary
• Dividends
• Pension contributions
• Repayment of a director’s loan
• Interest
• Capital on a future sale or liquidation

Each method has different tax and legal consequences.

For 2026/27, the dividend allowance is £500. Dividend income above the available allowance is taxed at:

• 10.75% within the basic rate band
• 35.75% within the higher rate band
• 39.35% within the additional rate band

The current rates can be checked in HMRC’s dividend tax guidance.

A company may therefore be more effective where profits are retained and reinvested. The benefit can be smaller where the landlord needs to withdraw most of the rental profit every year.

Transferring property can create Capital Gains Tax

Moving property to a company controlled by the landlord is normally treated as a disposal for Capital Gains Tax purposes.

The properties are generally treated as transferred at market value, even where:

• No cash changes hands
• The company issues shares
• The transfer price is below market value
• The company takes over the mortgage
• The landlord continues managing the properties

The gain is broadly calculated using the market value at the transfer date, less the landlord’s allowable purchase cost, qualifying improvement expenditure and transfer costs.

For 2026/27, individuals have a £3,000 annual exempt amount. Taxable gains are generally charged at 18% and 24%, depending on the individual’s taxable income and available basic rate band.

Available capital losses and reliefs may reduce the amount payable.

If CGT is due on the transfer of UK residential property, a UK property disposal report and payment may also be required within 60 days of completion.

Could Incorporation Relief defer the gain?

Incorporation Relief may defer some or all of the Capital Gains Tax where a business is transferred to a company in return for shares.

Broadly, the conditions require:

• A business to be transferred as a going concern
• The whole business to be transferred
• All business assets, other than cash, to be transferred
• The consideration to include shares issued by the company
• The relevant statutory conditions to be satisfied

The gain is generally rolled into the value of the shares received. This means the gain is deferred rather than eliminated.

HMRC provides an overview in its Incorporation Relief guidance.

Does every property portfolio qualify as a business?

No.

Receiving rent from one or more properties does not automatically mean the activity qualifies as a business for Incorporation Relief.

The level and nature of the landlord’s activities must be considered. Relevant factors may include:

• The number and type of properties
• The number of tenants
• The time spent personally managing the portfolio
• Responsibility for repairs and maintenance
• Tenant communication
• Advertising and arranging lettings
• Rent collection and arrears management
• Compliance and safety responsibilities
• Refurbishment and development activity
• Whether most work is delegated to agents

HMRC’s manual states that it should accept Incorporation Relief where an individual spends 20 hours or more each week personally undertaking activities indicative of a business. Cases involving fewer hours must be considered carefully.

This is HMRC guidance, not a simple statutory test. Spending 20 hours around the transfer date does not automatically establish that a qualifying business existed.

The activities should be genuine, regular and supported by evidence. Useful records can include:

• Management diaries
• Emails with tenants and contractors
• Repair schedules
• Inspection records
• Rent collection records
• Advertising and viewing records
• Compliance documentation
• Evidence of time spent managing the portfolio

The relevant HMRC guidance is available in its Capital Gains Manual.

Incorporation Relief is not an exemption

Where Incorporation Relief applies, the deferred gain normally reduces the tax cost of the company shares.

The historic gain has not disappeared. It may become taxable when the shares are later sold or otherwise disposed of.

Future events may also create separate tax charges. For example:

• The company may pay Corporation Tax when it sells a property
• The shareholder may pay tax when the proceeds are extracted
• A disposal of the company shares may release the deferred gain
• A liquidation may create shareholder tax consequences

The full exit strategy should therefore be considered before incorporation.

Stamp Duty Land Tax can be the largest upfront cost

A transfer to a connected company can create Stamp Duty Land Tax even if Incorporation Relief defers the Capital Gains Tax.

CGT Incorporation Relief does not provide an automatic SDLT exemption.

When an individual transfers property to a company they control, SDLT may be calculated using the property’s market value rather than the amount actually paid.

This means SDLT can arise even when:

• The transfer is described as a gift
• The company pays nothing in cash
• Shares are issued as consideration
• The company only takes over the mortgage
• The transfer produces no immediate cash for the landlord

HMRC confirms the market value treatment in its guidance on property transfers to companies.

Company residential property surcharges

Companies buying residential property in England or Northern Ireland are generally subject to the 5% higher rate surcharge.

A 17% rate can apply to certain company purchases of residential property costing more than £500,000. Relief may be available for qualifying property rental businesses, but the detailed conditions must be met.

Even where relief from the 17% rate applies, the usual company and additional property rates may still produce a substantial SDLT cost.

Land and Buildings Transaction Tax applies in Scotland, while Land Transaction Tax applies in Wales. Different rates, surcharges and relief conditions apply.

A jurisdiction specific calculation should be prepared before any transfer proceeds.

What if the portfolio is already a partnership?

Special SDLT rules can apply when property is transferred from a genuine partnership to a company.

In some circumstances, the partnership provisions in Schedule 15 of the Finance Act 2003 can reduce the amount on which SDLT is charged.

However, jointly owning property with a spouse, civil partner or another investor does not automatically establish a partnership.

A genuine partnership position normally needs evidence such as:

• A partnership agreement
• Partnership accounts and tax returns
• A partnership bank account
• Joint business activity
• An agreed profit sharing arrangement
• A history of operating as a business partnership
• Records showing the partnership owned or operated the relevant properties

The SDLT partnership rules are complicated and depend on the ownership before and after the transfer.

The test for CGT Incorporation Relief is also separate from the SDLT partnership rules. Qualifying for one does not guarantee relief from the other.

Be cautious about promoted LLP arrangements

HMRC has published warnings about arrangements marketed to landlords involving partnerships, limited liability partnerships and property companies.

Some schemes claim that landlords can:

• Transfer properties without CGT
• Avoid SDLT
• Create an increased property base cost
• Extract large amounts from a company tax free
• Move property between structures using artificial partnership steps

HMRC may challenge arrangements that do not reflect genuine commercial activity or that attempt to obtain unintended tax advantages.

In April 2026, HMRC updated its warning about certain property business arrangements involving hybrid partnerships and indemnities. HMRC has also published Spotlight 69, covering LLP arrangements marketed as avoiding CGT.

Landlords should be particularly cautious where advice is based on guaranteed tax savings, artificial partnership periods or claims that HMRC approval is unnecessary.

Mortgage refinancing must be agreed

Personal buy to let mortgages cannot normally remain unchanged when the company becomes the legal property owner.

The company may need new borrowing to:

• Repay the landlord’s personal mortgage
• Finance the property transfer
• Pay SDLT
• Pay legal and valuation costs
• Provide working capital

The lender will assess the company and its directors. Personal guarantees are commonly required.

Refinancing may also involve:

• Early repayment charges
• New arrangement fees
• Valuation fees
• Legal fees
• Higher interest rates
• Lower loan to value limits
• Additional security
• Restrictions on property type or tenancy arrangements

A potential tax saving can quickly be outweighed by higher borrowing costs.

Mortgage quotations should be obtained before making a final incorporation decision.

Can the company owe money to the landlord?

Depending on how the transfer is structured, the company may owe part of the property value to the landlord through a director’s loan account.

A genuine credit balance may later be repaid without being treated as salary or a dividend.

However, the amount that can be credited and the way consideration is structured can affect:

• Incorporation Relief
• The immediate CGT liability
• The shares issued
• Mortgage funding
• The company’s balance sheet
• Future withdrawals
• The commercial value of the company

A large director’s loan balance should not be created without a properly documented calculation and legal agreement.

The treatment of liabilities assumed by the company also requires careful review.

Personally carried forward losses do not move automatically

A landlord may have:

• Carried forward property losses
• Unused residential finance costs
• Capital losses
• Costs awaiting relief

These amounts do not automatically transfer to the company.

The company is a new taxpayer with its own property business. Personal property losses and unused finance costs generally remain with the individual.

If the individual ceases their personal property business completely, those amounts may not be usable unless the individual later has income from a qualifying personal property business.

This should be reviewed before transferring the last personally owned property.

What happens when the company sells a property?

A company does not receive the individual CGT annual exempt amount.

It generally pays Corporation Tax on its chargeable gain after deducting allowable costs, qualifying capital improvements and available company capital losses.

For properties acquired by a company before January 2018, limited Indexation Allowance may be available up to December 2017. No further indexation accrues after that date.

The sale proceeds belong to the company. If the shareholder wants to use the money personally, a separate tax charge may arise when the funds are withdrawn.

This can create two levels of taxation:

1. Corporation Tax on the company’s property gain.
2. Personal tax when the shareholder extracts the sale proceeds.

The outcome depends on whether money is taken as a dividend, salary, loan repayment, capital distribution or another approved method.

Selling company shares instead of the properties

In theory, the shareholder could sell the shares in the property company rather than the company selling the individual properties.

However, property company share sales can be difficult because buyers inherit the company’s:

• Tax history
• Liabilities
• Tenancy issues
• Borrowing
• Compliance risks
• Potential future tax on property gains
• Accounting records

Many buyers prefer to purchase the properties directly rather than acquire the company.

A future share sale should therefore not be assumed when preparing the incorporation calculation.

Annual Tax on Enveloped Dwellings

Annual Tax on Enveloped Dwellings, known as ATED, can apply where a company owns UK residential property valued at more than £500,000.

A property rental business may qualify for relief where the property is let commercially to an unconnected third party and the conditions are satisfied.

However, a filing obligation may still exist even when the relief reduces the charge to nil. HMRC states that a company may need to submit an ATED Relief Declaration Return.

Further information is available in HMRC’s ATED guidance.

ATED should be reviewed for each relevant property and valuation date.

Personal use of company property

Company-owned property should not be treated as the shareholder’s personal asset.

If a director, shareholder or connected person occupies the property, this may create:

• Employment benefit charges
• Company tax consequences
• ATED issues
• Restrictions on tax relief
• Rental and legal complications
• Additional reporting requirements

A company structure is normally most suitable where properties are held for genuine commercial letting.

Inheritance Tax and succession planning

A company can make it easier to transfer ownership gradually because shares can be transferred without changing the legal title to each underlying property.

Different family members may hold different share classes, subject to proper legal and tax advice.

However, incorporation does not automatically remove the portfolio from the landlord’s estate.

The company shares remain assets owned by the shareholder and may be subject to Inheritance Tax.

Property investment companies will also not usually qualify for Business Relief because businesses mainly holding land, buildings or investments are generally excluded. The official conditions are explained in HMRC’s Business Relief guidance.

Estate planning should therefore be considered separately from the Income Tax incorporation decision.

Additional company responsibilities

A property company creates ongoing obligations that do not apply in the same way to an individual landlord.

These may include:

• Annual statutory accounts
• Corporation Tax returns
• Companies House filings
• Confirmation statements
• Company bookkeeping
• Separate bank accounts
• Dividend documentation
• Director’s loan account records
• Payroll reporting where salaries are paid
• ATED filings where relevant
• Maintaining company registers
• Recording transactions with directors and shareholders

The company’s finances must be kept separate from the shareholder’s personal finances.

Rent received by the company cannot simply be withdrawn without being recorded and treated correctly.

Property administration must also be transferred

Tax is only one part of incorporation.

The parties may also need to update:

• Land Registry ownership
• Tenancy agreements
• Tenant notifications
• Deposit protection information
• Letting agent agreements
• Landlord insurance
• Property licences
• Utility accounts
• Service charge records
• Supplier contracts
• Rent collection instructions
• Local authority records
• Data protection documentation

Houses in multiple occupation and properties requiring selective or additional licensing may need particular attention. Some licences may not transfer automatically to the company.

When incorporation may be worth considering

Incorporation may be more attractive where:

• The portfolio has substantial mortgage borrowing
• The landlord pays higher or additional rate Income Tax
• Most rental profits will be retained
• The landlord plans to purchase more properties
• The investment horizon is long
• The portfolio involves significant personal management activity
• Incorporation Relief is likely to apply
• SDLT exposure is manageable
• Company mortgage terms are commercially acceptable
• There is a clear succession or investment strategy
• The landlord does not need immediate access to all rental profits

Even in these circumstances, a full calculation is required.

When incorporation may be less attractive

Incorporation may be less suitable where:

• The landlord needs to withdraw most rental profits
• The properties have large unrealised capital gains
• SDLT would be substantial
• Incorporation Relief is uncertain
• The portfolio has low borrowing
• Personal mortgages have favourable rates
• Early repayment charges are high
• The landlord expects to sell soon
• The properties were previously main residences
• There are significant personal property losses
• The portfolio is small
• Company compliance costs outweigh the tax benefit
• The owner may need to occupy a property personally

A company should not be created solely because another landlord has incorporated.

A hybrid approach may be possible

The decision does not always need to be all or nothing.

A landlord might:

• Retain existing properties personally
• Purchase future properties through a company
• Transfer only a separate qualifying business where appropriate
• Sell selected properties and reinvest through a company
• Review ownership between spouses or civil partners
• Reduce borrowing before considering a transfer
• Use a company for a new investment strategy

This can avoid triggering transfer taxes on the existing portfolio while allowing future company investment.

However, managing personal and company portfolios together requires clear records and separate bank accounts.

What should an incorporation comparison include?

A proper review should calculate:

1. The current market value of every property.
2. The capital gain on each property.
3. Available CGT reliefs and losses.
4. Whether Incorporation Relief is likely to apply.
5. SDLT, Land Transaction Tax or Land and Buildings Transaction Tax.
6. Mortgage redemption costs and company refinancing terms.
7. Legal, valuation and accounting fees.
8. Current personal rental profit and tax.
9. Company profit after finance costs.
10. Corporation Tax at the applicable rate.
11. Personal tax on planned withdrawals.
12. The treatment of director’s loan repayments.
13. The tax consequences of a future property sale.
14. ATED and other company filing requirements.
15. The effect on estate and succession planning.

Compare the long term cash position

The most useful comparison is not simply the first year’s tax saving.

The review should compare the cumulative cash position over several years, including:

• The immediate cost of transferring the portfolio
• Annual tax under personal ownership
• Annual tax under company ownership
• Mortgage costs under both structures
• Company compliance costs
• Tax on personal withdrawals
• Future property purchases
• Expected property sales
• The cost of eventually closing or selling the company

An incorporation that takes many years to recover its initial costs may not be worthwhile if the landlord expects to sell or change strategy before the break-even point.
