Incorporating Your Property Portfolio: Key Tax Considerations

By A D Pottie Chartered Accountants | July 2025

For landlords and property investors, choosing the right business structure is crucial. Incorporating your property portfolio — transferring it into a limited company — can bring tax efficiencies, improve protection, and support future growth. But it also comes with complex tax implications.

At A D Pottie, we help clients navigate this decision with tailored, strategic advice. Here’s what you need to know before taking the next step.

Why Incorporate?
One of the biggest motivations is tax efficiency.

Individuals may pay income tax on rental profits at rates up to 60%, once total income exceeds £100,000.

Companies, in contrast, pay corporation tax at rates between 19% and 26.5%, depending on profits.

Additional benefits of operating through a company include:

Tax-efficient profit extraction (e.g. dividends, pension contributions)

Full finance cost deductibility (see below)

Limited liability protection

Profit Extraction – Watch the Net Effect
Tax savings at the company level can be eroded when profits are distributed as dividends. Here’s an illustration for a company earning £10,000 in rental profit:

Taxpayer Type Total Tax Paid Effective Tax Rate
Basic Rate £2,565 25.65%
Higher Rate £4,465 44.65%
Additional Rate £4,891 48.91%

💡 Key point: If you plan to withdraw all profits, incorporation may not result in a lower total tax burden compared to personal ownership.

Mortgage Interest – A Major Advantage for Companies
Since 2020, individual landlords can no longer deduct mortgage interest as a direct expense. Instead, they receive a basic rate tax credit.

Companies, however, can still deduct 100% of their finance costs.

This means:

Lower taxable profits

More efficient debt repayment

Greater ability to reinvest

For landlords with borrowing, this is often a strong reason to consider incorporation.

Capital Gains Tax (CGT) on Transfer
Transferring properties to a company is treated as a disposal at market value for CGT purposes.

Taxable gains are charged at 18% or 24%, depending on your income.

Proceeds are often left on a director’s loan account, allowing for tax-free future withdrawals.

CGT is payable within 60 days of the transaction, even if no cash changes hands.

Deferring CGT with Incorporation Relief
In certain cases, CGT can be deferred by claiming Incorporation Relief under TCGA 1992, s 162. This applies if:

All business assets (except cash) are transferred

The transfer is in exchange for company shares

The business is transferred as a going concern

To qualify, your letting activity must be substantial — typically requiring 20+ hours per week, as seen in the Ramsay v HMRC [2013] case.

With relief:

The gain is deferred until the company shares are sold

The company’s base cost of the property is uplifted to market value

Stamp Duty Land Tax (SDLT) on Incorporation
SDLT applies on the market value of the properties transferred to the company.

Standard rates apply plus a 3% or 5% surcharge

No SDLT for properties under £40,000

Partnership exemptions may apply in some cases, subject to anti-avoidance rules

This is often one of the biggest upfront costs of incorporation and should be factored into your decision-making.

Should You Incorporate?
Incorporation can offer substantial tax benefits, but it’s not suitable for everyone. Key questions to consider:

✅ What is your current and expected future tax rate?
✅ Do you need to extract profits now or can you leave them in the company?
✅ How large is your current portfolio and what are the potential CGT and SDLT costs?
✅ Is your activity enough to qualify as a “business” for relief purposes?
✅ What are your long-term goals (e.g. succession, reinvestment, estate planning)?
