Property tax opportunities in a variable market

News & insights

Residential property has generally seen good growth over the very long term, with occasional years of robust or negative growth balancing out to about a 3-4% annual average, according to ONS data.

In 2025-2026, however, tax concerns and changes to letting rules, balanced against loosening planning laws, have left a variable picture across London and the Southeast. The story may be different further north and in the commercial property market. If a sale is required during a period of negative growth, there are opportunities for buyers to pick up property at low prices, but also tax opportunities for the ‘distress’ seller.

In this article we outline the key tax considerations to consider for the property owner and the opportunistic buyer.

The property owner

Crystallising a loss: sale to a third party

Where an owner is sitting on a property standing at a loss, crystallising that loss through a sale can be beneficial – especially if the owner has other properties standing at gains, which is often the case. Crystallising can be used to offset capital gains tax (CGT) on profitable investments, reducing overall tax liability.

The easiest way to crystallise a loss is to sell the loss property to a third party. This is not likely to raise concerns from HMRC. However, the loss rules can be quite restrictive and generally losses can only be offset against profits in the same year or future years. So timing is key.

Use of losses can also be quite restrictive. Capital losses are normally only offsetable against other capital gains, and the rules for individuals are more restrictive than for companies.

Writing down the property’s value

If timing of sale cannot be organised to allow offset, more thinking is required. For the owner who holds property as trading stock, a write-down of the value in the accounts is normally deductible. While there are sometimes psychological hurdles to overcome here, the ability to offset the loss should not be overlooked.

Sale to a connected person

For the person holding their property as an investment, write-down does not create a tax loss. Consideration can be given to crystallising the loss through a sale to a connected person. Connected persons for this purpose include spouses, civil partners and certain relatives.

Problems to be aware of:

  • The loss can only be used against gains made on sales to the same connected person. This is not fatal but means that sales of gain assets must be routed through the same connected person. That person can’t be the spouse, as no gain or loss arises on an inter-spouse transfer.
  • Transfer of the property can give rise to a stamp duty land tax (SDLT) charge that needs to be considered.

Losses on investments and loans

Where the property is held in a company, as well as the loss on the property itself, the owner may also be able to claim tax relief for their loss on the investment in the company, or on loans to the company. Although losses on shares are normally capital losses, in some cases it is possible to convert these into income tax losses.

Alternatives to selling: gifting a property

Not all owners nursing a loss need to sell. Many can afford to sit on the property and await better times.

Here there can be opportunities for a little estate planning where a parent wants to give away property to their children. A gift of a property is treated for capital gains purposes as a sale of the property at market value, even though the donor receives no cash. A downturn can offer an opportunity to make those gifts with little or no tax arising.

Letting on a temporary basis

Another common situation for property developers originally intending to sell their completed residential units is to let them for a period until the market picks up.

A problem arises if the developer has recovered VAT on the basis that they were going to sell. If they decide to let, that is exempt for VAT purposes and the VAT recovered may have to be paid back to HMRC.

An HMRC practice relating to developers letting on a temporary basis can help here. Or failing that, another possibility is to engineer a sale to a connected person which might enable VAT recovery to be maintained.

The direct tax and SDLT issues arising here can be complex and need to be considered alongside VAT.

Property incorporation

Some personal landlords, because of the unfavourable rules on tax deductibility of interest, are faced with negative cashflows after tax even though they are positive pre-tax. This is prompting many landlords to sell up.

An alternative approach is to incorporate the portfolio i.e. to transfer personally owned property to a company. There are plusses and minuses of incorporating and the process is not completely straightforward. There’s more information in our article on the potential tax pitfalls of property incorporation.

The opportunist property buyer

Buying debt

In some cases, consideration can be given to acquiring the debt funding the property rather than the property itself, especially where the amount of the loan has become more than the value of the property. Buying the debt will not normally give rise to SDLT, and so can be a considerable saving if the debt gives the buyer the control they need over the property.

In some cases, buying debt at a discount can give rise to a deemed taxable release of the debt, so this needs to be considered carefully. Happily, there are exemptions from this where the borrower is insolvent.

Buying the company

Another option is to buy the company that owns the property. A key benefit of buying the company is that stamp duty on shares is 0.5% compared to the much higher SDLT rates on buying the property.

Buying a company can be problematic if the property is standing at a gain, as it can lead to double tax when the buyer comes to sell. But where the property is standing at a loss, this issue goes away and could even lead to doubling up of losses!

The buyer may also be able to benefit from the high original cost base when they come to sell. This could significantly reduce or avoid tax on the eventual resale. There are anti-avoidance provisions which can prevent the use of a loss existing at the time of acquisition of a company, so this needs to be managed carefully. However, it won’t always apply where the loss is used to shelter the gain on the property owned by the company when the company was acquired.

Frequently Asked Questions: Property tax opportunities in a variable market

How is the current UK property market affecting tax planning?

Market conditions are mixed, creating tax planning opportunities around timing, valuations and transaction structures.

What does it mean to “crystallise a loss” on a property?

Crystallising a loss means selling a property that has fallen in value so the loss is formally recognised for tax purposes. This loss can offset gains on other properties, reducing overall CGT. Timing is key because losses are generally only usable in the same or future tax years.

Can I write down the value of my property to reduce tax?

Only if the property is held as trading stock (typically by developers). A write-down in accounts may be deductible. For investment property held on capital account, a write-down does not create a tax-deductible loss.

Can I sell a loss-making property to a spouse or family member to claim the loss?

Selling to a “connected person” can crystallise a loss, but the loss can only offset gains on future sales to the same connected person. SDLT may apply to the transfer. Transfers between spouses do not produce a gain or loss.

What other losses can I claim if I hold the property through a company?

If the property is held via a company, the owner may also claim losses on their shares in the company or loans made to it. In some cases, capital losses may be treated as income losses, offering potentially more favourable relief.

Are there tax advantages to gifting a property during a downturn?

Yes. A gift is treated as a sale at market value for capital gains purposes. In a downturn, this value may be low enough to make the gift with little or no CGT. This is often used for estate planning, such as passing property to children.

What are the VAT considerations if I temporarily let out a property instead of selling it?

If a developer originally intended to sell and claimed VAT recovery, letting the property (which is VAT-exempt) may require repaying VAT to HMRC. Some HMRC practices may help, or structuring a temporary sale to a connected person may preserve VAT recovery, but this must be carefully planned.

Should landlords consider incorporating their property portfolio?

Possibly. Some landlords experiencing negative cashflow after tax (due to interest deductibility restrictions) are considering company structures. Incorporation has pros and cons, and is not straightforward.

Is buying debt rather than the property itself a tax-efficient option?

Sometimes. If the loan on a property exceeds the property value (“distressed debt”), buying the debt can give control at lower cost, and debt purchases do not normally incur SDLT. However, buying discounted debt can trigger a taxable release of the debt, unless the borrower is insolvent.

What are the benefits and risks of buying a company that owns a property?

Benefits:

  • Stamp duty on shares is 0.5%, much lower than SDLT on property purchases
  • If the property stands at a loss, double taxation concerns are reduced
  • The buyer may inherit a high base cost, reducing future tax on sale

Risks:

  • Anti-avoidance rules may block the use of losses existing before the purchase
