Selling Your Rental to Your Own Limited Company: Is the Stamp Duty Refund Worth It?

The stamp duty surcharge stings. A landlord I spoke with last month had just paid it on a small terrace in Manchester and was already plotting how to get it back. His idea was to sell the property from himself to his own limited company, claim the surcharge as a business cost, and then deduct the mortgage interest against rental profits. On paper, that sounds tidy. In practice, I've looked at this exact move more than once and it rarely adds up for a single property.

What the surcharge is and why you don't get it back by selling

In England and Northern Ireland, Stamp Duty Land Tax (SDLT) is the purchase tax on residential property. The additional homes surcharge is an extra three percentage points on top of the normal rates when you buy a property that isn't your main home. Scotland and Wales have their own versions with different names and rates. When you sell a rental to your own limited company, you are not reclaiming the surcharge from your original purchase. Your company is making a fresh purchase and will pay SDLT at market value. A company buying a residential property is treated as a non-individual buyer and pays the surcharge, plus potentially a higher flat rate if the property is above a certain value. So the very tax you wanted to avoid gets paid again by the company, usually on a value that has gone up since you bought.

The mortgage interest maths looks better, but read the small print

Since 2017, the tax relief for mortgage interest as an individual landlord has been phased down. You now get a basic-rate tax credit on finance costs instead of deducting them from rental income before tax. That hurts higher-rate taxpayers. A limited company, by contrast, can treat mortgage interest as a normal business expense and deduct it from rental profits before corporation tax. For a landlord with a big mortgage, that single difference can save several thousand pounds a year. I once ran the projection for a two-bed flat I owned in my own name and the tax saving in year one was just under four figures. It got my attention, so I kept pulling the thread.

The costs that eat the saving

Selling to your own company is a disposal for tax purposes. That can trigger Capital Gains Tax (CGT) on any gain since you bought, even though no cash changes hands beyond the company's money. You'll need a formal valuation because the sale is between connected parties. Your mortgage lender will almost certainly make the company take out a new mortgage, and that means arrangement fees and an early repayment charge on your old loan if you're still inside a fixed term. Legal fees for the transfer and for setting up the company itself sit on top. Then there is the ongoing cost: a limited company files annual accounts and a corporation tax return every year. A basic property company can work with a bookkeeper and accountant, but that's a few hundred pounds a year even for a simple one.

When it might make sense, and when it plainly doesn't

If you plan to hold four or more properties long term and your personal tax rate is high, incorporation can be worth modelling. The company pays corporation tax at a lower rate than higher-rate income tax, and you can leave profits inside to fund the next purchase. For one or two rentals, the fixed costs usually outweigh the tax saving for the first five to seven years. I worked out the break-even on that flat I mentioned and it was just under seven years. I wasn't going to hold it that long, so I dropped the idea.

Raising the rent is simpler, but do it properly

Raising the rent doesn't require a solicitor, a new mortgage, or an accountant. For a periodic tenancy, you can serve a Section 13 notice to increase the rent once a year, though the tenant can challenge it at a tribunal. For a fixed-term tenancy, you need a rent review clause or the tenant's agreement. Before you send anything, look at comparable rents in the same postcode. If your rent is twenty percent below market, an increase closes a good slice of the tax gap without restructuring. The risk is losing a good tenant if you push too hard, so I'd rather have a modest increase with a stable tenant than a vacancy while I pay a conveyancer.

I'm not a lawyer or tax adviser, so before you transfer a property into a company, get your own advice on SDLT, CGT, and mortgage terms. But if you're holding a single rental and the idea was born out of stamp duty annoyance, run the numbers first. I did, and the answer was to raise the rent by what the market allowed and keep the property in my own name.
