What Does a Property Tax Advisor Actually Do?

A property tax advisor is a specialist accountant who deals with the tax consequences of buying, selling, developing, letting, or owning property through a business. This is not a generalist accountant who files your annual return and does your VAT. A proper property tax advisor understands the interaction between capital gains tax, stamp duty land tax (SDLT), VAT on property, inheritance tax, and corporation tax on property development.

Most UK business owners only need a property tax advisor when they are doing something unusual with property. Selling a buy-to-let. Converting a warehouse into flats. Buying a commercial unit for your own business. Passing a property portfolio to the next generation. Each of these triggers specific tax rules that are easy to get wrong.

As ICAEW qualified accountants, we see clients who have already made property decisions without specialist advice. The cost of fixing those mistakes is almost always higher than the cost of getting the advice upfront.

When You Definitely Need a Property Tax Advisor

Not every property transaction needs specialist input. Buying your own home is straightforward for most people. But once property touches your business, the complexity multiplies. Here are the situations where a property tax advisor is worth the fee.

Selling a Property Through Your Limited Company

If your limited company owns a property and you sell it, the gain is subject to corporation tax at 19% to 25%, depending on your profit level. That is different from selling a property in your personal name, where capital gains tax applies at 18% or 24% (or 14% to 18% if Business Asset Disposal Relief applies).

The choice of ownership structure matters enormously. A property tax advisor will look at whether the property should have been held personally, in a company, or in a partnership before you sell. If you are already in the wrong structure, there may be ways to extract the property tax-efficiently before a sale. But those options narrow the closer you get to completion.

Take a real example. A Manchester-based construction company owner owned a commercial unit personally that his company used. He wanted to sell it for £420,000. His base cost was £180,000. The gain of £240,000 would have attracted CGT at 24% as a higher-rate taxpayer: £57,600. With proper planning, we transferred the property into the company before sale using incorporation relief. The gain was deferred. The company then sold it and paid corporation tax at 19% on the gain, with the proceeds available for reinvestment without the immediate tax hit. That saved him roughly £12,000 in year one.

Claiming Business Asset Disposal Relief on a Property Sale

Business Asset Disposal Relief (BADR) applies to the sale of a business or shares in a trading company. It can also apply to the sale of land or buildings used by your business if you sell them as part of selling the business itself. The relief caps the CGT rate at 14% for disposals from 6 April 2025, rising to 18% from 6 April 2026.

The problem is that BADR has strict conditions. The property must have been used for the purposes of the business. It must be disposed of as part of the business sale, not separately. And the business must be a trading business, not an investment business. A property tax advisor will check whether your property qualifies before you agree a sale price.

If you sell a property that was used by your company but you sell it personally after the company has stopped trading, BADR may not apply. The timing matters. A property tax advisor will plan the sequence of events to preserve the relief.

Buying a Commercial Property Through Your Business

When you buy a commercial property through your limited company, you pay SDLT at commercial rates. The current rates start at 0% up to £150,000, then 2% on the portion from £150,001 to £250,000, and 5% above that. For properties over £250,000, the rates are higher.

But there is a trap. If you buy a property that includes residential elements, such as a flat above a shop, the SDLT treatment changes. The residential SDLT rates are higher, and there is a 3% surcharge on additional dwellings. A property tax advisor will structure the purchase to avoid overpaying SDLT while staying within HMRC's rules.

There is also the VAT question. If you buy a new commercial property (less than three years old), VAT is usually payable on top of the purchase price. If the seller has opted to tax the property, VAT applies even on older properties. You need to check this before exchange. If you cannot recover the VAT, it becomes a real cost. A property tax advisor will flag this early and help you decide whether to opt to tax the property yourself.

Developing Property Through a Company

Property development is treated as trading by HMRC, not investment. That means the profits are subject to corporation tax, not capital gains tax. The distinction matters because the reliefs available on capital gains (like BADR or holdover relief) do not apply to trading profits.

A property tax advisor will help you structure development projects correctly from the start. Should you set up a special purpose vehicle (SPV) for each project? Should you hold the land personally and develop through a company? Should you use a joint venture structure? Each option has different tax consequences, and the wrong choice can cost tens of thousands.

There is also the question of VAT on development costs. If you are developing a residential property for sale, you can normally recover the VAT on construction costs under the VAT DIY housebuilders scheme or by registering for VAT and charging it on the sale. But the rules are specific. You cannot recover VAT on materials if you are not registered. A property tax advisor will ensure you are registered at the right time and claiming the right inputs.

Letting Property Through a Company

Many UK business owners hold buy-to-let properties in limited companies to avoid the restrictions on mortgage interest relief that apply to personally held properties. Since April 2020, individual landlords cannot deduct mortgage interest from rental income at their marginal rate. Companies can still deduct it as a trading expense.

But holding property in a company creates other issues. Corporation tax on rental profits at 19% to 25% may be lower than income tax, but extracting the profits as dividends triggers dividend tax at up to 39.35%. A property tax advisor will model whether the company structure actually saves you money over the long term, factoring in the dividend tax on extraction and the CGT on eventual sale.

There is also the question of associated companies. If you own multiple companies that hold property, they may be associated for corporation tax purposes. That reduces the profit thresholds for the small profits rate and marginal relief. A property tax advisor will review your structure and advise whether consolidation or separation makes sense.

Passing Property to the Next Generation

Property is often the most valuable asset in a family business. Passing it to children or other family members without triggering a large tax bill requires careful planning. Inheritance tax (IHT) applies at 40% on estates above the nil-rate band of £325,000. Business Property Relief (BPR) can reduce or eliminate IHT on qualifying business assets, including property used by a trading business.

But BPR does not apply to investment property. If your company holds buy-to-lets, those properties do not qualify for BPR. If your company holds property that you use for your own trading business, it may qualify. A property tax advisor will help you separate the investment property from the trading property before it is too late.

There is also the question of holdover relief. If you gift property to a family member during your lifetime, holdover relief can defer the capital gain until they sell it. But holdover relief is not available on gifts of property that is not used for a business. A property tax advisor will structure the gift to qualify for relief.

When You Might Not Need a Property Tax Advisor

Not every property transaction justifies the cost of specialist advice. If you are buying your own home through a standard mortgage, you do not need a property tax advisor. If you are selling a personally held buy-to-let and the gain is within your annual exempt amount (£3,000 for 2025/26), the tax is minimal. If you are letting a single property through a standard limited company with no development or sale planned, a good general accountant can handle it.

The threshold is roughly this: if the transaction involves more than £100,000 of value, or if there is any complexity around structure, reliefs, or timing, get advice. The cost of a property tax advisor is typically between £250 and £500 per hour, or a fixed fee of £1,000 to £5,000 for a full review. That is cheap compared to the cost of a mistake.

How to Choose a Property Tax Advisor

Not all accountants are property tax advisors. You want someone who deals with property transactions regularly. Ask them how many property transactions they handled in the last 12 months. Ask them which reliefs they have claimed for clients. Ask them whether they have experience with SDLT, VAT on property, and capital gains tax on commercial property.

At Holloway Davies, our ICAEW qualified team handles property tax advice for clients across the UK. We work with limited companies, contractors, sole traders, and partnerships who own or transact property. We do not just file the return. We structure the deal to minimise tax from the start.

If you are buying, selling, developing, or letting property through your business, get in touch. We will tell you whether you need specialist advice and what it would cost. If the transaction is straightforward, we will say so.
