Using Airbnb and Long Term Lets in One Property: The Record Keeping Trap

Using the same property for Airbnb stays and long term tenants can be commercially flexible, but it creates accounting and tax risks. Income may arrive through different platforms, expenses may overlap, and the property can move between short stay and residential use during the year.

The key issue is not simply how much rent the property earns. Landlords must be able to show where income came from, when the property was available for each type of letting and how shared costs were allocated.

Why Mixed Letting Creates Problems

A property might be let to a tenant for several months, used for Airbnb weekends during vacant periods and occasionally occupied by the owner. Without clear records, it becomes difficult to calculate taxable profit accurately.

Common problems include:

• Airbnb income recorded net of platform fees instead of gross
• Long term rent mixed with Airbnb payouts in one bank account
• Cleaning, linen and guest supplies claimed against periods of residential letting
• Council Tax, utilities and insurance costs claimed without a fair allocation
• Personal stays treated as business availability
• Mortgage interest, repairs and refurbishment costs coded incorrectly
• Platform income missing from the Self Assessment return

HMRC expects landlords to keep records that support rental income and expense claims. A bank statement alone is rarely enough where Airbnb fees, refunds, deposits and cleaning charges are involved.gov

Airbnb Income Is Not the Same as a Bank Payout

Airbnb normally pays a host after deducting service fees, refunds, adjustments and sometimes tax related amounts. The amount received in the bank account is therefore not always the gross income figure for tax reporting.

A landlord should record:

Export Airbnb transaction reports regularly. Match each booking to the payout, rather than posting one monthly bank receipt as income.

Long Term Rent Needs Separate Tracking

Long term residential rent should also be recorded gross. Letting agent statements may show rent after management fees, repairs, compliance charges or other deductions. These figures must be separated to produce accurate property accounts.

Use separate income codes for:

• Airbnb accommodation income
• Airbnb cleaning income
• Long term rent
• Letting agent deductions
• Deposit amounts retained for damage
• Guest or tenant reimbursements
• Refunds and credits

This does not necessarily mean the income is taxed in separate businesses. It means the records must show how the total has been built up and which costs relate to each activity.

The Furnished Holiday Letting Change

Before 6 April 2025, a property meeting the furnished holiday letting conditions could benefit from a separate tax regime. Those rules have now been abolished, so Airbnb income does not automatically receive furnished holiday letting treatment merely because guests stay for short periods.

For most individual landlords, income from UK residential property, including short stays and long term lets, is now reported within the UK property business. However, the underlying letting activity still matters for VAT, business rates, Council Tax, expense allocation and evidence of commercial use.

Allocating Shared Expenses

Some costs relate to the whole property and must be allocated fairly where Airbnb use, long term letting and private use overlap.

Examples include:

The allocation should be reasonable, consistent and evidence based. A simple approach may use days available for Airbnb, days occupied by long term tenants and days of private use. However, a cost that relates only to one activity should be allocated directly rather than split equally.

Private Use Is a Key Risk

The property is not commercially available for letting when the owner, family or friends use it without paying a market rent. Expenses for that private period may need to be restricted.

Keep a calendar showing:

• Airbnb guest stays
• Long term tenancy start and end dates
• Void periods when the property was actively marketed
• Owner, family or friend stays
• Repairs or refurbishment closures
• Days when the property was unavailable for other reasons

This calendar can support expense allocations and explain why income changed between years.

VAT and Local Charges

Residential letting is generally exempt from VAT. However, short stay accommodation can be standard rated when it amounts to hotel type or holiday accommodation, subject to VAT registration requirements and the detailed facts.

The current VAT registration threshold is £90,000 of taxable turnover. Exempt residential rent does not count towards taxable turnover, but taxable Airbnb accommodation income may. A landlord with both types of income should monitor the position carefully.

Council Tax and business rates can also differ depending on the property’s use and location. In England, a property used for short term lets may be assessed for business rates if it meets the relevant availability and letting conditions, while an ordinary residential let is commonly subject to Council Tax. Check the local authority position before assuming the charge.

A Practical Record Keeping System

Create one digital folder for the property and maintain records monthly.

• Keep a calendar for every letting, void and private use day
• Export Airbnb reservation and transaction reports each month
• Keep long term tenancy agreements and letting agent statements
• Use separate bank categories for Airbnb, long term rent, cleaning, fees and repairs
• Retain invoices for maintenance, furniture, appliances and safety checks
• Record why a refund, deposit deduction or guest payment occurred
• Keep evidence that void periods were actively marketed
• Reconcile income received against platform and agent reports
• Review VAT taxable turnover every quarter
• Keep records for at least five years after the relevant Self Assessment filing deadline

A Short Example

A landlord receives £18,000 from long term rent and £14,000 in gross Airbnb booking income during the tax year. Airbnb deducts £500 of platform fees and £1,200 of guest refunds. The landlord should not report only the £12,300 net Airbnb payout.

The accounts should normally begin with £14,000 gross Airbnb income, then show £500 fees and £1,200 refunds separately. Adding the £18,000 residential rent gives total gross property income of £32,000 before other allowable expenses.

Clear records make it easier to identify the correct taxable result and avoid overstating or understating turnover.
