What Is An SA105 Form?

Updated: Nov 14, 2023

Understanding the SA105 Form and Its Relevance

In the UK, the SA105 form is an essential document for taxpayers with property income. It serves as a supplementary form to the SA100, the main self-assessment tax return form. The SA105 specifically addresses income from UK property, playing a crucial role in the tax filing process for landlords, property investors, and those earning income from property-related activities.

What Is the SA105 Form?

The SA105 form is a supplementary document for recording income from UK property on your SA100 tax return​​​​. It becomes relevant when you have income from:

  • Rental income from UK properties, including platforms like Airbnb.

  • Income from letting furnished holiday accommodation in the UK or the European Economic Area (EEA).

  • Premiums received from leasing UK land.

  • Inducements related to property letting.

However, it's not used for foreign property income, income from Real Estate Investment Trusts (REITs), or peer-to-peer property loans​​.

Filing Requirements and Who Needs to Use It

The SA105 is needed if you receive a total income of over £1,000 from various sources, such as UK land or property, letting furnished rooms in your home, furnished holiday lets in the UK or EEA, premiums from leasing land, and inducements to let a property​​.

Interestingly, there's a property allowance – a tax exemption up to £1,000 per year for individuals with property income. If your property income is £1,000 or less, you're exempt from notifying HMRC, but for income over £1,000, you'll need to submit a self-assessment tax return including the SA105 pages​​.

Completing the SA105 Form

When filling out the SA105, you'll need:

  • Your name and Unique Taxpayer Reference (UTR).

  • Information about your UK properties, such as the number of properties rented out, joint ownership details, and if you're claiming Rent a Room Relief.

  • Details on furnished holiday lets, including income, expenses, and reliefs.

  • Information about your UK property income, excluding FHLs, REITs, or Property Authorised Investment Funds distributions.

  • Details of any allowable tax-deductible expenses, which reduce your taxable income.

  • Finally, you'll calculate your taxable profit or loss, incorporating any adjustments or reliefs claimed​​.
