Flat rate expenses (also known as “simplified expenses“) are flat rates that you can use to reduce your self-employment taxes.

You can claim flat rate expenses for:

• working from home: between £10 and £26 per month, depending on how much time you spend working from home
• driving to your clients or work site: between 25p and 45p per mile, depending on how many miles you drive and what kind of vehicle you use (even bikes are eligible)
• living at your business premises: between £350 to £650 per month, depending on how many members of your family live there.
