HMO licensing fees are tax deductible for UK landlords as revenue expenses against rental income. The mechanics are straightforward in principle: mandatory HMO licences, additional licences, selective licences, and renewal fees are all allowable. Where landlords trip up is the timing rules (cash basis vs accruals), the capital-vs-revenue split on conversion work to meet licence conditions, and the treatment of professional fees on the application itself. This guide covers the practical detail.
For the broader question of HMO tax (Section 24, allowable expenses, room-by-room accounting, the personal-vs-company decision) see our dedicated HMO tax guide. For comparison between HMO and standard buy-to-let, see our HMO vs standard BTL comparison.
The Legal Basis: Why HMO Licence Fees Are Deductible
The deductibility flows from the wholly-and-exclusively rule in ITTOIA 2005. Under the cash basis (s.34), an expense is deductible if it is incurred wholly and exclusively for the rental business. Under the accruals basis (s.272), the same test applies and the expense is matched to the period it relates to. HMO licences are required by statute (Housing Act 2004 Part 2 for mandatory licensing; Part 3 for additional and selective schemes operated by individual councils), so the wholly-and-exclusively test is satisfied for any property let as an HMO.
HMRC's Property Income Manual confirms the position at PIM2080 (revenue expenses) and PIM2090 (allowable expenses checklist).
The Three Types of HMO Licence Fee
| Licence type | When it applies | Typical fee (5-year licence) |
|---|---|---|
| Mandatory HMO licence | Any HMO with 5+ occupants forming 2+ households (national rule, all councils) | £600-£1,500 per property |
| Additional HMO licence | Smaller HMOs (typically 3-4 occupants forming 2+ households) where the council operates an additional licensing scheme | £450-£900 per property |
| Selective licence | Any private rental (HMO or single-let) in a defined geographic area where the council operates a selective licensing scheme | £400-£800 per property |
A single property can require more than one licence type. A 5-bedroom HMO in a council ward with selective licensing needs both the mandatory HMO licence and the selective licence. Both fees are independently deductible.
Cash Basis vs Accruals: Which Year Do You Claim?
The default position for individual landlords is the cash basis, which became the standard regime for property businesses from 6 April 2024. Under the cash basis:
- You deduct the licence fee in the tax year you actually pay it
- A five-year licence paid in March 2026 takes the full deduction in the 2025/26 tax year
- No need to spread the cost across the licence period
You must move to accruals basis if your gross rental income exceeds £150,000. Under accruals:
- You spread the licence fee across the licence period in line with the matching principle
- A £1,000 five-year licence produces a £200 annual deduction
- The unspread portion sits on the balance sheet as a prepayment
Limited company landlords cannot use the cash basis. Companies are always on accruals and must spread licence fees across the licence period. The corporation tax computation includes the appropriate annual share rather than the full payment.
You can elect into accruals voluntarily even below the £150k threshold, but switching back and forth between bases creates timing distortions, so most landlords pick one and stick with it.
Capital vs Revenue: The Conversion Costs Question
This is the area where most HMO landlords lose deductions or claim incorrectly. The rule:
- Conversion work to bring the property up to HMO standard (additional fire doors, additional kitchens or bathrooms, sound insulation between rooms, structural changes to room layout, replacement of single-glazed windows to meet thermal standards) is capital expenditure. It adds to the property's base cost for CGT on eventual sale. It does not reduce this year's rental tax bill.
- Maintenance and replacement of existing equipment (replacing a broken fire door with an equivalent one, servicing fire alarms, replacing the boiler, ongoing redecoration) is revenue expenditure. It is deductible against rental income in the year incurred (cash basis) or accrued (accruals basis).
- Statutory compliance certificates (annual gas safety, EICR every 5 years, EPC every 10 years, fire risk assessment) are revenue expenditure and deductible in the year incurred.
The HMRC test is whether the work creates or enhances an asset (capital) or maintains an existing asset (revenue). A fire door that did not previously exist is capital. Replacing an existing fire door is revenue. A new kitchen carved out of what was previously a bedroom is capital. Replacing a worn-out kitchen with an equivalent one is revenue.
The capital-vs-revenue boundary is one of the most-litigated areas of property tax. If the work is substantial and the position is not obvious, get advice before filing.
Professional Fees on the Licence Application
Application support costs are deductible to the extent they are revenue, not capital. Examples:
- HMO consultant fee for filing the application: deductible (revenue, application-related)
- Surveyor fee for the layout drawing required by the council: deductible if the drawing is only used for the application; capital if the drawing also underpins planned conversion work
- Fire risk assessment by a competent specialist: deductible (revenue, statutory compliance)
- Architect's fee for HMO conversion design: capital (follows the conversion expenditure)
- Solicitor fee for licence application appeal or compliance dispute: deductible (revenue, defending the rental business)
- Solicitor fee for negotiating the original property purchase: capital (acquisition cost, adds to base cost for CGT)
The principle: follow the underlying expenditure the professional fee supports. Professional fees inherit the capital-vs-revenue character of the work they enable.
Late Application Penalties and Council Fines
Council-administered penalty notices for late HMO licence applications, late renewals, or technical breaches of licence conditions are generally deductible. The position rests on the duality test: the penalty arose in the course of the rental business and not for a personal purpose. HMRC will generally allow council penalty fees as a trading expense.
The position changes for court-imposed fines (for example, criminal convictions for operating an unlicensed HMO). HMRC's view, supported by case law (McKnight v Sheppard), is that court fines are not deductible because the duality of purpose is broken. The fine has a punitive character beyond the cost of doing business. The civil penalty / criminal fine distinction matters here.
HMO Licence Fees Across UK Councils
Fee schedules vary significantly. Always check the current rate at your local authority before budgeting. Indicative fees in May 2026:
| Council | Mandatory HMO licence (5-year) | Selective / additional schemes |
|---|---|---|
| London (varies by borough) | £500-£1,500 | Many boroughs operate selective licensing; check the specific ward |
| Manchester | ~£1,100 | Selective licensing in defined wards, ~£640 |
| Birmingham | ~£780 | Selective licensing in multiple wards, £500-£780 |
| Leeds | ~£1,200 | Property-specific additional schemes |
| Liverpool | Mandatory HMO fee plus city-wide selective licensing at ~£750 | Combined cost across both regimes |
| Newcastle | ~£900 | Selective licensing in named areas |
| Nottingham | ~£1,150 | Selective licensing across most of the city |
All of the above are deductible. Portfolio landlords with HMOs across multiple councils should track fees property-by-property to ensure all licensing costs are captured on the tax return.
Pre-Trading Expenditure: Licence Fees Paid Before First Let
If you have applied for an HMO licence before the property is first let, the fee is still deductible under the pre-trading expenditure rule in ITTOIA 2005 s.57. The conditions:
- The expense must be incurred within seven years of the rental business starting
- The expense must be wholly and exclusively for the rental business
- The expense must not be capital
- The deduction is taken in the first tax year of letting, not the year the expense was paid
This matters for landlords who buy a property, refurbish it to HMO standard, apply for the licence, and only start letting in the following tax year. The licence fee deduction sits in the year letting commences, not the year of payment.
Record-Keeping Under MTD for Income Tax
From 6 April 2026, sole-trader landlords with combined gross property and self-employment income above £50,000 must keep records digitally and submit quarterly updates to HMRC under Making Tax Digital for Income Tax Self Assessment. The threshold drops to £30,000 from April 2027 and £20,000 from April 2028.
For HMO licence fees specifically:
- Council invoice (PDF or screenshot from the council portal)
- Bank statement entry showing the payment
- Licence certificate confirming validity period
- Renewal notices and correspondence
- Professional fee invoices (consultant, surveyor, solicitor) attributed to the application
All of this must live inside MTD-compatible software, not in paper files or unlinked spreadsheets. See our best MTD software for landlords guide for tooling recommendations.
