Tax & Simplified Expenses for SoleTraders, Business Partnerships with no Companies as Partners

Simplified expenses are a way of calculating some of your business expenses using flat rates instead of working out your actual business costs.

You don’t have to use simplified expenses. You can decide if it suits your business.

Simplified expenses can’t be used by limited companies or business partnerships involving a limited company.

Types of expenses

You can use flat rates for:

  • business costs for vehicles
  • working from home
  • living in your business premises

You must calculate all other expenses by working out the actual costs.

How to use simplified expenses

  1. Record your business miles for vehicles, hours you work at home and how many people live at your business premises over the year.
  2. At the end of the tax year use the flat rates for vehicles, working from home, and living at your business premises to work out your expenses.
  3. Include these amounts in the total for your expenses in your Self Assessment tax return.

Use the simplified expenses checker to compare what you can claim using simplified expenses with what you can claim by working out the actual costs. This will help you work out if simplified expenses suits your business.

Vehicles

Calculate your car, van or motorcycle expenses using a flat rate for mileage instead of the actual costs of buying and running your vehicle, eg insurance, repairs, servicing, fuel.

You can’t claim simplified expenses for a vehicle you’ve already claimed capital allowances for, or you’ve included as an expense when you worked out your business profits.

Vehicle Flat rate per mile with simplified expenses
Cars and goods vehicles first 10,000 miles 45p
Cars and goods vehicles after 10,000 miles 25p
Motorcycles 24p

Example

You’ve driven 11,000 business miles over the year.

Calculation:

10,000 miles x 45p = £4,500
1,000 miles x 25p = £250
Total you can claim = £4,750

You don’t have to use flat rates for all your vehicles. Once you use the flat rates for a vehicle, you must continue to do so as long as you use that vehicle for your business.

You can claim all other travel expenses (eg train journeys) and parking on top of your vehicle expenses.

Use the simplified expenses checker to compare what you can claim using simplified expenses with what you can claim by working out the actual costs.

Working from home

Calculate your allowable expenses using a flat rate based on the hours you work from home each month.

This means you don’t have to work out the proportion of personal and business use for your home, eg how much of your utility bills are for business.

The flat rate doesn’t include telephone or internet expenses. You can claim the business proportion of these bills by working out the actual costs.

You can only use simplified expenses if you work for 25 hours or more a month from home.

Hours of business use per month Flat rate per month
25 to 50 £10
51 to 100 £18
101 and more £26

Example

You worked 40 hours from home for 10 months, but worked 60 hours during 2 particular months:

10 months x £10 = £100
2 months x £18 = £36

Total you can claim = £136
