What Does an Accountant for Landlords Actually Do?

If you own one rental property in Manchester, your tax return is straightforward. You declare the rental income, deduct allowable expenses, and pay tax on the profit. A decent tax software package can handle it.

If you own four properties across Bristol, Leeds, and Birmingham, structured through a mix of personal ownership and a limited company, with mortgage interest, capital allowances on fixtures, and the occasional holiday let thrown in, you are in a different league. That is where a specialist accountant for landlords earns their fee.

This guide explains exactly what a property-focused accountant does, when you need one, and what you should expect to pay. No fluff. Just the practical decisions you face as a UK landlord.

Why a General Accountant and a Landlord Accountant Are Different

A general practice accountant handles VAT returns, payroll, and standard corporation tax for a mix of clients. They know the rules. But they do not live and breathe property tax. The difference shows in the details.

Take mortgage interest restriction. Since April 2020, you cannot deduct mortgage interest as an expense against rental income if you own property personally. Instead, you get a 20% tax credit. That changes the whole calculation of whether to hold property in a limited company or in your own name. A general accountant might tick the box. A landlord specialist will model both scenarios with your actual numbers.

Or take capital allowances on residential property. Most accountants assume they do not apply to residential lets. They are wrong. If you buy a property that was previously used as a business premises, or if you install specific fixtures like lifts, air conditioning, or fire safety systems, capital allowances may be available. A specialist knows where to look.

The same applies to furnished holiday lettings, the rent-a-room scheme, and the tricky interaction between property income and your personal tax bands. A specialist accountant for landlords sees the full picture. A generalist sees a form to fill in.

What a Landlord Accountant Actually Does for You

The day-to-day work breaks down into five main areas. Here is what each involves.

1. Portfolio Structuring and Tax Planning

This is the most valuable thing an accountant does. It is not about compliance. It is about designing the ownership structure so you pay less tax over the lifetime of your portfolio.

Key decisions include:

• Should you hold properties in your personal name or through a limited company?
• If through a company, should each property have its own SPV (special purpose vehicle) or sit under one company?
• Should you use a partnership or an LLP for joint ownership with a spouse or business partner?
• How do you extract profits tax-efficiently: salary, dividends, or directors' loan account?
• What happens when you sell? Business Asset Disposal Relief (BADR) at 14% (rising to 18% from April 2026) versus the standard 24% CGT rate on residential property.

These decisions are not one-size-fits-all. A landlord with a portfolio worth £1.2m in Manchester's Northern Quarter faces different choices from someone with a single buy-to-let in Bristol's Harbourside. Your accountant should run the numbers for your specific situation.

2. Capital Allowances and Property Allowances

Most landlords overpay tax because they miss capital allowances they are entitled to. The rules changed significantly in recent years, and many accountants have not kept up.

Key allowances to consider:

• Structures and Buildings Allowance (SBA): 3% per year on qualifying construction costs for new commercial buildings or conversions. This applies to holiday lets and some mixed-use properties.
• Plant and machinery allowances: Available for fixtures like lifts, heating systems, and security systems in commercial or mixed-use properties.
• Furnished Holiday Let (FHL) allowances: FHLs qualify for full capital allowances on furniture, fixtures, and equipment. Standard residential lets do not.
• Replacement of Domestic Items Relief: For standard residential lets, you can claim the cost of replacing furniture, furnishings, and appliances. Not the initial cost. The replacement cost.

A specialist accountant will review your property purchases and identify claims you may have missed. Some firms offer a capital allowances review as a separate service. It often pays for itself in the first year.

3. Mortgage Interest and Finance Costs

The mortgage interest restriction changed the game for personally-held property. You now get a 20% tax credit on finance costs, not a deduction at your marginal rate.

Here is how it works in practice.

Suppose you are a higher-rate taxpayer with rental income of £30,000 and mortgage interest of £15,000. Under the old rules, you would pay tax on £15,000 profit at 40%: £6,000. Under the current rules, you pay tax on £30,000 income at 40%: £12,000. Then you get a 20% credit on the £15,000 interest: £3,000. Your total tax bill is £9,000. That is £3,000 more than before.

If you hold the same property through a limited company, the company deducts the mortgage interest in full as a business expense. Corporation tax at 19% or 25% applies to the profit. The difference can be substantial.

Your accountant should run this comparison with your actual numbers before you buy another property. If you are already holding personally, they should model the cost of transferring into a company, including the SDLT and CGT implications.

4. VAT and Stamp Duty Land Tax (SDLT)

Most residential landlords are not VAT-registered because residential rents are exempt from VAT. But if you own commercial property, mixed-use property, or holiday lets, VAT becomes relevant.

Key VAT points for landlords:

• Option to Tax: If you own commercial property, you can opt to charge VAT on the rent. This lets you recover VAT on purchase costs and refurbishment. But it makes the property less attractive to tenants who cannot recover VAT.
• Flat Rate Scheme: Some property businesses qualify for the flat rate scheme. The rate for property-related services is 14% (limited cost trader rate 16.5% if you do not spend enough on goods).
• SDLT surcharges: Additional 3% SDLT on second homes and buy-to-lets. Higher rates for corporate buyers (15% on properties over £500k, with exceptions for property development and rental businesses).
• Annual Tax on Enveloped Dwellings (ATED): If you hold a high-value residential property (over £500k) through a company, ATED may apply. The annual charge ranges from £4,150 to £280,500 depending on property value.

These are specialist areas. A general accountant may not flag them until HMRC sends a letter. A landlord specialist will plan for them upfront.

5. Compliance and Filing

This is the baseline. Your accountant should handle:

• Self assessment tax returns (SA100, SA105 property pages) for personally-held property.
• Corporation tax returns (CT600) for company-held property.
• VAT returns if registered.
• Confirmation statements and annual accounts for limited companies.
• P11D and payroll if you employ staff or take a salary from your property company.
• 60-day CGT return on UK residential property disposals.

But compliance alone is not worth paying a premium for. Any accountant can file a return. The value comes from the planning that sits underneath the compliance.

When Should You Hire a Specialist Accountant for Landlords?

Not every landlord needs a specialist. Here is a rough guide.

You probably do not need one if:

• You own one or two properties in your personal name.
• Your rental income is below £20,000 per year.
• You have no mortgage interest or it is very small.
• You are happy to use tax software and file yourself.

You should consider one if:

• You own three or more properties.
• Your portfolio is held across a mix of personal and company ownership.
• You have mortgage interest over £10,000 per year.
• You are considering incorporating your portfolio.
• You own commercial property or holiday lets.
• You are planning to sell a property and want to minimise CGT.
• Your total property income pushes you into the higher or additional rate tax bands.

You definitely need one if:

• You have a portfolio worth over £1m.
• You use a limited company structure.
• You have complex financing arrangements (joint mortgages, equity release, bridging loans).
• You are involved in property development or trading as well as letting.
• HMRC has opened an enquiry into your property affairs.

If any of those apply, the cost of a specialist accountant is likely to be outweighed by the tax savings they identify. We have seen cases where a capital allowances review alone saved a client £18,000 in the first year.

What Does a Landlord Accountant Cost?

Fees vary by firm, location, and complexity. Here are typical ranges for 2025/26.

• Basic compliance only (1-2 properties, personal name): £300 to £600 per year for self assessment filing.
• Limited company with 1-5 properties: £1,000 to £2,500 per year for accounts, CT600, and personal returns.
• Larger portfolio (6+ properties, mixed structures): £2,500 to £6,000 per year or more.
• Capital allowances review (one-off): £500 to £2,000 depending on portfolio size.
• Portfolio restructuring advice (one-off): £1,000 to £5,000 depending on complexity.

Some accountants charge by the hour (£150 to £400 per hour for specialist property work). Others charge a fixed annual fee. Fixed fees are more common and give you certainty on cost.

Ask upfront what is included. Does the fee cover all personal and company returns? Does it include advice during the year or just the year-end compliance? Do they charge extra for HMRC enquiries? Get it in writing.

How to Choose the Right Accountant for Your Property Portfolio

Not every firm that says they work with landlords actually knows property tax. Here is how to separate the specialists from the generalists.

Ask these questions in your initial call:

• How many landlord clients do you currently have?
• What is your approach to mortgage interest restriction for personally-held property?
• Do you routinely review capital allowances on new property purchases?
• Have you handled a property incorporation before? Can you walk me through the process?
• What software do you use for bookkeeping and tax returns?
• Do you have experience with furnished holiday lettings and the HMRC criteria?
• Are you ICAEW, ACCA, or CIMA qualified? (Professional body membership matters for technical competence and indemnity insurance.)

Red flags to watch for:

• They tell you a limited company is always better (it is not).
• They say capital allowances never apply to residential property (they sometimes do).
• They cannot explain the difference between the rent-a-room scheme and the property allowance.
• They quote a fixed fee without asking about your portfolio structure first.
• They are not registered with a recognised professional body.

At Holloway Davies, our ICAEW qualified team includes specialists who work with property investors across the UK. We see portfolios ranging from single buy-to-lets in Leeds to mixed commercial and residential portfolios in London's Canary Wharf and Edinburgh's Leith. We do not take a one-size-fits-all approach because your portfolio is not one-size-fits-all.

What Happens When You Engage a Landlord Accountant

Here is a realistic timeline of what to expect in your first year.

Month 1: Onboarding and discovery. You provide details of all properties, ownership structures, financing, and prior tax returns. The accountant reviews your current position and identifies immediate issues.

Month 2: Planning and restructuring. If needed, the accountant models different structures and presents options. This might include incorporating, changing how you extract profits, or claiming missed allowances.

Month 3 to 11: Ongoing compliance and bookkeeping. You send income and expense records monthly or quarterly. The accountant reviews them and flags issues. If you use cloud software like Xero, FreeAgent, or Hammock (popular for BTL landlords), the accountant can access your data in real time.

Month 12: Year-end and filing. The accountant prepares your tax return, corporation tax return, and any other filings. They present the tax bill and suggest payment planning.

Throughout the year: Ad hoc advice. You call or email when you are about to buy, sell, or refinance a property. The accountant tells you the tax implications before you commit.

That last point is the most important. The best time to involve your accountant is before you make a decision, not after. A quick call before exchanging contracts can save you thousands in SDLT or CGT.

Common Mistakes Landlords Make Without Specialist Advice

We see the same patterns repeatedly. Here are the most expensive ones.

1. Holding property personally when a company would be better. If you are a higher-rate taxpayer with significant mortgage interest, the company structure almost always wins on tax. But transferring later triggers SDLT and CGT. Do it right the first time.

2. Not claiming capital allowances. Many landlords miss SBA on commercial conversions or plant and machinery on mixed-use properties. The claims can be backdated, but the process gets harder the longer you wait.

3. Mixing personal and business finances. Using your personal bank account for property income and expenses creates a bookkeeping nightmare. It also makes it harder to prove deductions if HMRC enquires. Open a separate business account for each property or entity.

4. Ignoring the 60-day CGT reporting rule. If you sell a UK residential property, you must report and pay the CGT within 60 days of completion. Miss the deadline and you face penalties and interest. This applies even if you make no gain and owe no tax.

5. Not reviewing the rent-a-room scheme. If you let a furnished room in your own home, the first £7,500 of income is tax-free. Many landlords with a single lodger miss this and overpay tax.

6. Using the wrong accounting basis. Most landlords use the cash basis (tax on income received, expenses paid). But the accruals basis may be better if you have significant prepayments or trade creditors. Your accountant should advise on which basis applies.

Final Thoughts: Is a Specialist Accountant Worth It?

If your property portfolio is simple, a good tax software package and a general accountant will probably do. But as soon as you have multiple properties, financing, or a limited company, the complexity multiplies. The tax rules for property are among the most fiddly in the UK system. One missed allowance or wrong structure can cost you thousands each year.

A specialist accountant for landlords does not just file your return. They plan your structure, identify claims you missed, and keep you compliant. The fee is typically 0.5% to 1% of your portfolio value per year. If they save you 2% to 5% in tax, you are ahead.

If your portfolio is growing or you are considering a structural change, get in touch. We can review your current position and tell you whether a specialist approach would pay for itself.
