Why You Need a Specialist HMO Accountant
HMO properties have unique tax considerations that general accountants often miss. A specialist understands multi-tenant income structures, higher allowable expenses, and the specific reliefs available to HMO landlords.
Section 24 tax planning
Navigate the mortgage interest restriction and plan your structure (personal vs limited company) to minimise the impact on your HMO portfolio.
Capital allowances
Claim allowances on fixtures, furnishings, and integral features that general accountants routinely miss in HMO conversions.
Multi-tenant income reporting
Correctly report room-by-room rental income, void periods, and deposits across multiple tenancies within a single property.
Compliance and HMRC enquiries
Ensure your returns are bulletproof. Specialists know the red flags HMRC looks for in HMO portfolios and can represent you in enquiries.
Expense optimisation
Maximise deductible expenses unique to HMOs — communal area costs, licensing fees, fire safety equipment, and higher maintenance spend.
What HMO Accounting Services Include
A good HMO accountant should offer more than just filing your return. Expect proactive advice tailored to your portfolio.
Annual self-assessment or corporation tax returns
Quarterly management accounts and cash flow forecasting
Tax-efficient structuring advice (personal vs SPV vs partnership)
Capital allowances claims on HMO conversions and refurbishments
VAT guidance if you provide services alongside accommodation
Stamp Duty Land Tax advice for HMO purchases
Year-end tax planning to minimise liability
Typical HMO Accountant Fees
Fees vary based on portfolio size, structure, and complexity. HMO specialists often charge more than generalists but typically save you more in tax.
| Service | Typical Cost |
|---|---|
| Self-assessment (1–3 HMOs) | £300–£600 per year |
| Self-assessment (4+ HMOs) | £500–£1,200 per year |
| Limited company accounts | £800–£2,000 per year |
| Capital allowances claim | £500–£1,500 (one-off or % of claim) |
| Tax planning consultation | £150–£350 per hour |
Fees vary by region and firm. London and the South East tend to be higher. Many firms offer fixed-fee packages.
How to Choose an HMO Accountant
Not every property accountant understands HMOs. Here's what to look for.
HMO portfolio experience
Ask how many HMO landlords they work with. They should understand room-by-room letting, licensing costs, and the higher expense ratios HMOs generate.
Proactive tax advice
The best accountants don't just file returns — they plan ahead. Ask about their approach to year-end planning and structure reviews.
Professional qualifications
Look for ACCA, ACA, or CIOT qualified accountants. Check they have professional indemnity insurance and are registered with a recognised body.
Transparent pricing
Get a clear fee schedule upfront. Avoid firms that charge by the hour without caps — fixed-fee arrangements give you certainty.
Key Tax Considerations for HMO Landlords
Understanding these areas will help you have a more productive conversation with your accountant and ensure nothing is missed.
Section 24: Mortgage interest is no longer fully deductible for individual landlords — a 20% tax credit replaces the old relief
Incorporation: Moving HMOs into a limited company can save tax but triggers SDLT and CGT — get specialist advice first
Capital allowances: HMO conversions often qualify for significant claims on fixtures and integral features
Furnished holiday let rules: Some serviced HMOs may qualify for more favourable tax treatment
Replacement of domestic items relief: Claim the cost of replacing furniture, appliances, and furnishings in tenanted rooms
Allowable expenses: Licensing fees, safety certificates, communal utility bills, and cleaning costs are all deductible

Frequently asked questions
Do I need a specialist accountant for my HMO?
While any qualified accountant can file your return, HMO properties have unique tax considerations — capital allowances on conversions, multi-tenant income structures, and higher allowable expenses. A specialist typically saves more in tax than the extra they charge.
Should I hold my HMO in a limited company?
It depends on your income, portfolio size, and growth plans. Limited companies pay corporation tax (currently 25%) and avoid Section 24 restrictions, but transferring existing properties triggers SDLT and CGT. A specialist accountant can model both scenarios for your situation.
What expenses can I claim on an HMO?
HMO-specific deductible expenses include licensing fees, fire safety equipment, communal utility bills, cleaning of shared areas, furniture replacement, safety certificates (gas, electrical, EPC), insurance, and management fees. Your accountant should review all of these annually.
How much can I save with capital allowances on an HMO conversion?
Capital allowances on HMO conversions typically range from 15% to 35% of the total conversion cost, depending on the work done. On a £150,000 conversion, that could mean £22,000 to £52,000 in allowances — reducing your tax bill significantly. Claims must be supported by a specialist surveyor report.
