How do we calculate your relevant home office expenses?

There’s an easy way to claim what you’re owed

Who are Beany? 

Perhaps you’ve turned a spare bedroom into an office. Or, you could be storing stock in a shed you’ve got out the back. If you’re doing either of these, it’s likely that some of your household costs are overlapping with operational business costs.​

The costs directly related to producing income for your business – which may include rent, mortgage interest, electricity, rates, insurance, and telecommunication bills – can all be recorded as business expenses. However, this all depends on you setting things up the right way.​

How do we calculate your relevant home office expenses?

First, we need to understand the physical area of your home being dedicated to work.​

You need to calculate the total physical area in the house that’s dedicated to business. Here’s an example:​

  • The house has a total of 8 rooms
  • 1 of these rooms is used for storing stock for the business, 80% of the time it is used for this purpose, with the remaining 20% of the time it being used as a spare bedroom for guests. 
  • 1 of the rooms is used as a home office, 75% of the time it is used as a home office with the other 25% of the time it is used as a home gym. 
  • If my electricity bill is £200 I would be able to claim the following as a tax deductible expense:
    £200 / 8 rooms = £25 per room
    Room 1 used 80% of the time for business use: 80% * £25 = £20 
    Room 2 used 75% of the time for business use: 75% * £25 = £18.75
    Total tax deductible expense: £20 + £18.75 = £38.75

Alternatively, you could work out the proportion of the house used for business purposes on a square footage basis, rather than on the number of rooms. ​

This calculation can be applied to:​

  • Interest on a mortgage, or rent
  • Insurance (both home and contents)
  • Rates (water and land)
  • Electricity and gas
  • Security and alarms costs
  • Internet
  • Telephone costs

Other, more specific expenses can also be claimed such as repairs and maintenance work on the areas designated for business.​

There’s an easy way to claim what you’re owed

It’s as simple as keeping a record of your costs.​

Save your invoices and bank statements to your Google Drive or keep a spreadsheet and your Beany accountant will review them when it’s time to prepare your financial statements. From there, we’ll work out what can and can’t be claimed!​
