Track Expenses & Keep Receipts/Invoices

Firstly, it is incredibly important you keep track of all of your expenses. This is something you need to do regularly. Little and often is key.

Rent & Mortgage

If you are working from home you are allowed to expense a portion of your rent to the business. If you have a dedicated room, this will be based on the square meters of the room as a percentage of the total area of your home.

It is recommended you do not try to expense your mortgage. It will be taxed as income so there’s no benefit in doing so. You can try to expenses the interest only portion but make sure this is excluded from your mortgage interest relief which is due to end 31/12/2020. The rent a room scheme does not apply to businesses renting space.

Similar to rent you can expense both of these. If you live alone you would expect the percentage to be much higher than your rent. 

Phone & Internet

Generally, it’s better practice to have a separate phone for business and personal calls. It’s easier to track and calculate what the business expense is.

You are allowed to use your business phone for personal use and you will not be liable for benefit in kind if the use is minimal and it does not result in additional charges to the business.

Furniture & Equipment

As mentioned above you can claim a capital allowance against the cost of office furniture and equipment in your home. These assets are assumed to have a useful life of 8 years which means you can expenses 12.5% of the purchase price each year.

You can also use these assets for personal use as long as this use is minimal and does not result in additional costs to the business.
