How to Transfer Property to a Limited Company Without a Massive Tax Bill

Transferring a buy-to-let property into a limited company is treated by HMRC as a sale at market value, triggering capital gains tax on the landlord and stamp duty land tax on the company, but incorporation relief under section 162 TCGA 1992 can defer the entire capital gains charge where the portfolio is run as a genuine business. That single distinction, between a portfolio that is a business and one that is a passive investment, decides whether property company incorporation costs a landlord tens of thousands of pounds or almost nothing in capital gains tax. Blue Tick Accountants, a Guildford-based UK tax advisory and accountancy practice, works with landlords across the country on exactly this decision. This article sets out the two tax charges incorporation creates, the reliefs that reduce them, the mortgage and lender problems that catch landlords out, and a decision framework for portfolios of different sizes.

Key Takeaways

• Transferring property to your own limited company is a disposal at market value for capital gains tax purposes, because you and the company are connected persons under section 286 TCGA 1992, even if no money changes hands.
• Capital gains tax for 2026/27 is charged at 18% within the basic rate band and 24% above it, with an annual exempt amount of £3,000.
• Incorporation relief under section 162 TCGA 1992 defers the whole gain into the base cost of the shares received, but only where the letting activity amounts to a business and the entire business is transferred as a going concern in exchange wholly or partly for shares.
• A limited company pays the 5% higher rates for additional dwellings on top of standard SDLT from its very first residential purchase, and SDLT is charged on market value even where the property is gifted.
• Corporation tax is charged at 19% on profits up to £50,000 and 25% on profits above £250,000 for the 2026/27 tax year, with marginal relief in between.
• Extracting rental profits from a company costs dividend tax at 10.75%, 35.75% or 39.35% in 2026/27, after a £500 dividend allowance, so incorporation only pays where profits are retained or reinvested.

Why are landlords moving buy-to-let property into a limited company?

Landlords incorporate primarily because the Section 24 finance costs restriction denies higher rate relief on mortgage interest for individuals, while a limited company deducts interest in full as a trading expense. For a higher rate taxpaying landlord with substantial borrowing, the difference is large enough to turn a taxable profit into a real loss.

Take a landlord with £60,000 of rental income, £25,000 of mortgage interest and £8,000 of other expenses, taxed at 40%. As an individual, taxable profit is £52,000, giving income tax of £20,800 less a 20% finance cost credit of £5,000, so £15,800 is payable. Held in a company, the same portfolio produces taxable profit of £27,000 and corporation tax at 19% of £5,130, an annual saving of £10,670 before extraction.

That figure is only half the calculation. Money inside a company is not yours until you take it out, and the dividend tax rates that apply on extraction erode the advantage for landlords who need the rental income to live on. A limited company buy-to-let structure works best where profits are retained to buy further property.

How much capital gains tax is due on transferring property to your own company?

Capital gains tax on incorporation is calculated on the market value of each property at the date of transfer, less its original cost and allowable improvement expenditure, regardless of what the company pays you. The connected persons rule in section 286 TCGA 1992 overrides the actual consideration, so transferring at cost or as a gift does not avoid the charge.

Worked example: a landlord owns four properties worth £1,200,000 in total, bought for £700,000, producing a combined gain of £500,000. Deducting the £3,000 annual exempt amount leaves £497,000. At the 24% rate applying above the basic rate band, capital gains tax of £119,280 falls due, payable within 60 days of completion under the UK property reporting rules.

Incorporation relief removes that charge entirely in the right circumstances. Where the whole of the letting business, including all the properties and its liabilities, is transferred as a going concern to a company in exchange wholly or partly for shares, the gain is rolled into the base cost of those shares. The landlord above receives shares worth £1,200,000 with a deemed base cost of £700,000, and pays nothing now. The relief applies automatically where the conditions are met, but those conditions are demanding.

When does a property portfolio count as a business for incorporation relief?

A property portfolio qualifies as a business for section 162 purposes where the landlord's activity involves a significant degree of active management, judged on the facts rather than on the number of properties owned. The leading authority is Ramsay v HMRC (2013), where roughly 20 hours a week of hands-on work across a single converted building was accepted as a business.

There is no statutory property count and no safe harbour. HMRC looks at the time spent, whether that time is the owner's own or a letting agent's, the services provided to tenants, and whether the activity is organised in a business-like way. A landlord with three agent-managed flats, spending two hours a month reviewing statements, is very unlikely to qualify. A landlord with eight properties personally handling lettings, viewings and repairs has a strong case, and any credible landlord incorporation guide UK assessment starts by documenting that time.

Can you avoid the SDLT charge when incorporating a portfolio?

Stamp duty land tax is charged on the market value of the properties transferred to a connected company under section 53 FA 2003, and it is the cost that most often makes incorporation uneconomic. Using the £1,200,000 portfolio above, a company purchase attracts SDLT of £6,250 on the first £125,000 at 5%, £8,750 on the next £125,000 at 7%, £67,500 on the slice to £925,000 at 10%, and £41,250 on the balance at 15%, a total of £123,750.

One route removes it. Where the properties are held in a genuine partnership rather than as jointly owned personal investments, the partnership incorporation provisions in Schedule 15 FA 2003 can reduce the chargeable consideration to nil, because the partners' interests in the properties are mirrored in their shareholdings. The partnership must be real, evidenced by a partnership agreement, registration with HMRC, partnership tax returns and a business bank account, and it must have existed for a meaningful period beforehand. HMRC challenges arrangements created shortly before a transfer.

Multiple dwellings relief was abolished for transactions completing on or after 1 June 2024. Six or more dwellings acquired in a single transaction can still be treated as non-residential, taxed at rates topping out at 5%, which is a material saving for larger portfolios.

What do mortgage lenders and ongoing costs add to the property company incorporation decision?

Every existing buy-to-let mortgage must be redeemed and replaced with company borrowing, because a personal mortgage cannot follow the property into a company. Early repayment charges on fixed-rate products commonly run to 1% to 5% of the balance, and new arrangement fees are typically 1.5% to 2% of the loan.

Company rates usually sit 0.5 to 1 percentage point above equivalent personal products, and most lenders require personal guarantees from the directors. On £700,000 of borrowing, a 0.75 percentage point premium costs £5,250 a year, which can consume half of a projected tax saving. Legal, valuation and accountancy fees for the transfer commonly add £5,000 to £15,000.

As a working framework, landlords with one or two mortgage-free properties rarely benefit. Landlords with three to five geared properties need the SDLT problem solved through a genuine partnership before the numbers work. Landlords with six or more geared properties, higher rate income and an intention to reinvest profits are where a landlord incorporation guide UK analysis most often comes out positive, and where a limited company buy-to-let structure repays its setup cost within a few years.

Frequently Asked Questions

Do I have to pay stamp duty if I gift my rental property to my own company?

Yes. Stamp duty land tax is charged on the market value of a property transferred to a connected company, not on the price paid, under section 53 Finance Act 2003. A gift of a £300,000 rental property to your own company still produces SDLT of £20,000, calculated at the 5% higher rates for additional dwellings.

Does incorporation relief need to be claimed on my tax return?

No. Incorporation relief under section 162 TCGA 1992 applies automatically where the conditions are met, so no claim is required. The conditions are that a business, not merely an investment, is transferred as a going concern with all its assets other than cash, and that the consideration is wholly or partly in shares. You can elect to disapply the relief if that produces a better result.

How many properties do I need before HMRC accepts my portfolio is a business?

There is no minimum number. HMRC assesses the degree of activity, not the property count, following Ramsay v HMRC (2013) where around 20 hours a week of active management was accepted. Landlords who personally handle lettings, repairs and tenant issues across a portfolio have a stronger case than those whose properties are fully managed by an agent.

Will I pay more tax overall by holding buy-to-let in a company?

Possibly, if you need the rental income. Company profits are taxed at 19% up to £50,000 and 25% above £250,000 for 2026/27, then taxed again on extraction at dividend rates of 10.75%, 35.75% or 39.35% after the £500 dividend allowance. A limited company buy-to-let structure is most tax-efficient where profits are retained and reinvested rather than drawn.

Can I move just one property into my company and keep the rest personally?

You can, but incorporation relief will not apply. Section 162 requires the whole of the business to be transferred as a going concern, so a partial transfer leaves the full capital gain chargeable at 18% or 24%. Stamp duty land tax at the 5% higher rates is payable on the market value in either case.

How Blue Tick Can Help

Blue Tick Accountants models property company incorporation for landlords in full, comparing the upfront SDLT and capital gains tax cost against the projected annual saving, and testing whether the portfolio meets the business test for incorporation relief before anything is transferred. The analysis covers partnership structuring, lender requirements and the long-term extraction cost, so the decision rests on real numbers rather than a headline tax rate. Head to our website and book a meeting now.

Conclusion

Incorporation is a tax-efficient move for a minority of landlords and an expensive mistake for the rest. The deciding factors are whether the portfolio genuinely qualifies as a business for incorporation relief, whether a real partnership exists to solve the stamp duty problem, and whether the rental profits can be left inside the company rather than drawn out. Run the full calculation, including refinancing costs and early repayment charges, before instructing a solicitor. A transfer that looks attractive on the annual tax saving alone can take a decade to recover its upfront cost.
