Why Property Investors and Landlords Need a Specialist Accountant for Property

Property Tax Is Not Like Other Business Tax

If you own rental property in the UK, you have probably noticed that the tax rules are different from those for a standard limited company or sole trader business. Mortgage interest relief has been restricted since 2017. Stamp Duty Land Tax (SDLT) surcharges apply to additional properties. Capital gains on property sales have their own reporting deadlines and rates. And if you incorporate a property portfolio, the rules around incorporation relief are specific and unforgiving.

A general practice accountant might handle your annual self assessment return without issue. But when you are making decisions about buying, holding, refurbishing, or selling property, you need an accountant who specialises in property tax. An accountant for property will know the reliefs, the traps, and the planning opportunities that a generalist may miss.

At Holloway Davies, our ICAEW qualified team works with landlords, property investors, and property developers across the UK. We see the same mistakes repeated. This article explains why a specialist property accountant is worth the fee and what you should look for when choosing one.

What Makes Property Tax Different?

Mortgage Interest Restriction

If you hold rental property personally (not through a limited company), you cannot deduct your mortgage interest as a business expense. Instead, you receive a 20% tax credit on the interest paid. This means higher-rate and additional-rate taxpayers lose a significant tax benefit compared to basic-rate taxpayers.

A general accountant may calculate the credit correctly. But a specialist accountant for property will plan around the restriction. For example, they may advise transferring properties into a limited company structure, or restructuring borrowing to maximise the credit you do receive.

The restriction does not apply to limited companies. Companies deduct mortgage interest as a normal business expense. That is one reason many landlords have incorporated over the last few years. But incorporation is not always the right move. SDLT on the transfer, capital gains on the disposal, and ongoing compliance costs all factor in. A specialist will model the numbers before you make the leap.

SDLT Surcharges and Multiple Dwellings Relief

Buying a residential property in the UK triggers SDLT. If you already own a property, you pay a 3% surcharge on top of the standard rates. For companies buying residential property worth over £500,000, the surcharge is 15% unless the property qualifies for relief.

Multiple Dwellings Relief (MDR) was abolished from 1 June 2024. If you bought multiple properties before that date, you may still have claims to make. A specialist property accountant will know the transitional rules and whether you can still benefit.

SDLT planning is not just about getting the rate right. It is about structuring purchases to minimise the tax bill. A general accountant may not spot the difference between buying as an individual, as a company, or through a partnership. A specialist will.

Capital Gains Tax on Property

Selling a residential property that is not your main home triggers capital gains tax at 18% (basic rate) or 24% (higher rate). You must report the gain to HMRC within 60 days of completion using the 60-day CGT property return. Fail to do that, and you face penalties and interest.

If you sell a property you have lived in, you may qualify for Private Residence Relief. That can eliminate the gain entirely for the period you lived there, plus the final 9 months of ownership. Lettings Relief was restricted from April 2020 and now only applies if you shared occupation with a tenant.

A specialist accountant for property will calculate the gain correctly, apply the right reliefs, and ensure the 60-day return is filed on time. They will also plan disposals to use your annual CGT exemption (£3,000 for 2025/26) efficiently across multiple tax years.

Business Asset Disposal Relief for Property

If you sell a property used in a trading business, you may qualify for Business Asset Disposal Relief (BADR). The rate is 14% for disposals from 6 April 2025, rising to 18% from 6 April 2026. The lifetime limit is £1 million.

Property letting is not normally a trade for BADR purposes. But if you are a property developer or a furnished holiday lettings business, you may qualify. The rules around what counts as a trade are specific. A general accountant may not spot the opportunity. A specialist will.

What a Specialist Property Accountant Does

Structure Advice Before You Buy

The most expensive mistakes in property investment happen before you buy. Should you buy personally or through a limited company? Should you buy jointly with a spouse or a business partner? Should you use a partnership or an LLP?

Each structure has different tax consequences for income, gains, and SDLT. A specialist accountant for property will model the scenarios using your actual numbers. They will consider your current income, your plans for the property, and your long-term exit strategy. They will not recommend a one-size-fits-all answer.

For example, a client buying a £350,000 rental property in Birmingham's Jewellery Quarter might be better off buying personally if they are a basic-rate taxpayer and plan to sell within five years. But if they are a higher-rate taxpayer with a large portfolio, a limited company structure may save them tens of thousands in tax over the long term. The difference comes down to the specific numbers.

Ongoing Compliance and Tax Planning

Once you own property, the compliance requirements stack up. You need to file self assessment returns showing rental income and expenses. If you use a limited company, you need corporation tax returns (CT600) and annual accounts. If you have multiple properties, you need to track income and costs per property to calculate gains accurately on disposal.

A specialist property accountant will set up your bookkeeping in software like Xero or FreeAgent, with separate nominal codes for each property. They will ensure you claim all allowable expenses: repairs (not improvements), letting agent fees, insurance, ground rent, service charges, and professional fees. They will also advise on capital allowances for fixtures and fittings in furnished properties.

They will also handle the 60-day CGT returns when you sell. Missing that deadline is easy to do if you are not expecting it. A specialist will have the process embedded in their workflow.

Incorporation and Exit Planning

Transferring a property portfolio into a limited company is a complex transaction. It triggers SDLT on the transfer and capital gains on the deemed disposal. Incorporation relief can defer the gain, but only if the conditions are met. The relief is not automatic. You must claim it correctly.

A specialist accountant for property will assess whether incorporation makes sense for your specific portfolio. They will calculate the upfront tax costs, the ongoing tax savings, and the break-even period. They will also advise on how to extract profits from the company tax-efficiently, using a mix of salary and dividends.

Exit planning is equally important. If you plan to sell the company (not the properties), you may qualify for BADR on the shares. But the company must be a trading company, not an investment company. The distinction between trading and investment for property companies is a grey area. A specialist will structure the company's activities to maximise the chance of qualifying.

When Should You Hire a Specialist Property Accountant?

If you own one rental property and your tax affairs are simple, a good general accountant may be sufficient. But if any of the following apply, you should consider a specialist:

• You own three or more rental properties
• You are considering incorporating your portfolio
• You are a higher-rate or additional-rate taxpayer with mortgage interest
• You have sold a property in the last 60 days
• You are buying or selling a property worth over £500,000
• You run a furnished holiday lettings business
• You are a property developer or trader
• You have overseas property or non-resident status

In each of these scenarios, the tax stakes are high. A mistake can cost you thousands. A specialist accountant for property will pay for themselves many times over in tax saved and penalties avoided.

How to Choose the Right Property Accountant

Not every accountant who says they handle property is a specialist. Ask these questions before you engage one:

• How many property clients do you have?
• Do you handle SDLT returns and 60-day CGT returns in-house?
• Can you show me a worked example of incorporation relief?
• Do you advise on capital allowances for residential property?
• Are you familiar with the rules for furnished holiday lettings?

A genuine specialist will answer these questions confidently and with specific examples. A generalist will give vague answers or try to change the subject.

At Holloway Davies, we are ICAEW qualified and work with property investors across the UK, from a single buy-to-let landlord in Camden to a portfolio of 20 properties in Manchester's Northern Quarter. We handle the full range of property tax work, from compliance to planning to exit strategy. If you want to speak to someone who understands property tax, contact our team.

The Cost of Not Having a Specialist

Let us put some numbers on it. A higher-rate taxpayer with a £200,000 mortgage on a rental property paying 5% interest will pay £10,000 in interest per year. Under the restricted regime, they receive a 20% tax credit worth £2,000. If they were a basic-rate taxpayer, they would get the same credit. But a general accountant may not flag that the restriction exists, or that restructuring the borrowing could reduce the effective cost.

Now consider a property sale. A client sells a property for £400,000 that they bought for £200,000. The gain is £200,000. If they miss the 60-day reporting window, HMRC charges penalties starting at £100 and rising to £1,500 or more. Interest accrues on the unpaid tax from the due date. A specialist ensures the return is filed on time and the gain is calculated correctly, including any allowable costs and reliefs.

Over the life of a property portfolio, the difference between a general accountant and a specialist accountant for property can easily run into five figures. That is not a marketing claim. It is the arithmetic of the UK property tax system.

Final Thoughts

Property tax is not getting simpler. The mortgage interest restriction, SDLT surcharges, and the 60-day CGT reporting regime are all relatively recent changes. More are likely. A specialist property accountant keeps up with the changes so you do not have to.
