Sell, keep or incorporate your buy to let? How to compare the options

Comparing the three options for a buy to let in 2026: selling and Capital Gains Tax, keeping it under Section 24, or moving it into a limited company.

Higher tax under Section 24, the Renters’ Rights Act and higher property income tax rates from April 2027 have many landlords asking the same question: should I sell, keep going as I am, or move into a company?

Option 1: sell

Selling ends the tax on rent but triggers Capital Gains Tax on the gain. For residential property the rates are 18% within the basic rate band and 24% above it, after the £3,000 annual exempt amount. The gain has to be reported and the tax paid within 60 days of completion.

ItemExample
Bought for, including costs£150,000
Sold for, after costs£250,000
Gain£100,000
Less annual exempt amount£97,000 taxable
Capital Gains Tax at 24%£23,280

Option 2: keep

Keeping the property personally means paying Income Tax on the rent with Section 24: mortgage interest isn’t deducted, and you get a 20% tax credit instead. The government has announced that property income tax rates will rise by 2 percentage points from April 2027, with the finance cost credit rising to match. For higher-rate taxpayers with mortgages, that can make the tax bill high compared with the cash the property makes.

Option 3: incorporate

A limited company can deduct mortgage interest in full and pays corporation tax at 19% to 25%. But moving existing property into a company is normally treated as a sale at market value: there can be Capital Gains Tax, and the company pays stamp duty on the market value, including the 5% surcharge. Taking money out as dividends is taxed again. Some reliefs can apply in particular cases, so take advice before you act.
