The short version: SA105 is the UK property supplementary form. You use it to report rental income from UK properties or furnished holiday lets in the UK and EEA.
What goes on it?
Your rental income, allowable expenses, and the resulting profit or loss. If you have multiple properties, you usually combine them on one SA105.
What about overseas property?
That goes on SA106 (foreign income) instead. SA105 is specifically for UK and EEA furnished holiday lets.
Filing online?
The property section is built into the online return. Enter your figures there instead of filling in a paper SA105.
