Initial considerations –use of home as office (HMRC) 

Use home as office and dealing with administration

Many businesses across the UK operate from home. As a result, at least all or most of the administration will be dealt with there. Therefore, as part of this, while you are contracting or trading, as a UK business owner you will need to know:

When you carry out business-related activities from home, it is also good to know how to create an office at home.

It is also worth a note, in a minority of cases, that far more of the business activity than merely the administration side of things is done from home.

Setting up your home office 

Besides making a claim for use of home as office, when you deal with business administration and other tasks, you will need to use specific equipment to do this. Therefore, you may have a business computer and associated equipment to carry out most of your work.

When you think about creating your contractor office at home, it is best to have a separate room, and it is best to keep work-related areas separate from personal ones. Therefore, once you decide where your working space will be, let us consider what you can claim as business expenses.

What can you claim

The cost of furnishing a dedicated contractor office at home will include:

  • Carpets.
  • Curtains.
  • Flooring.
  • Desks.
  • Filing cabinets.

It is not advisable to claim for any structural changes to your property in respect of your home office. If you were to do this you may have Capital Gains Tax implications to deal with later when you sell your property.

Computer and electronic equipment

As part of your new office at home, you can claim a business computer and other relevant electronic equipment through your business. If you have a landline for business reasons, you can claim this cost if it is a dedicated business phone line.

What can you use your business computer for

On your business computer, besides using this to maintain your accounting records, you may also use this to:

  • Write official company letters.

HMRC use of home as office allowance 2021/22, 2022/23 and 2023/24 -what to consider? 

Is it fair to claim home office use when you work from home?

We think, on balance, it only seems fair that the business owner should be able to make some form of a claim for use of home allowance. Basically, the claim for your contractor home office expenses should be the business proportion of the contractor office expenses you incur when you run a home office that you use in part for such purposes.

The best option is to avoid a tax cost for you as the business proprietor/homeowner when you make a claim for use of home as office. Indeed, for you to do so, you mustn’t be making a profit when you claim tax relief for working from home. It is also vital that you do not describe the payment as rent. If the business pays you rent, then this will be taxable income for you as an individual.

Therefore, you will need to find a way to determine the amount of any payment for using your home as an office. Some costs, such as Council Tax, stay the same; if you perform contract work from home, you should not include these.

Other expenses which you should not claim for your contractor office as work from home tax deductions will include:

  • The cost of buying the home (this includes the mortgage payments).
  • The rent.
  • The cost of insurances for your business. If your business insurance is up for renewal, you can now receive a great contractor discount of 10% by using Code CAUK10 at checkout on policies from one of the best contract insurance providers in the UK.
  • Possibly the water rates.

But you do perform contractor work from home sometimes

When you buy your home, it would be ideal to have a separate room where you can work. You could use this room just for business use, and this room would be beyond the number that the household ordinarily requires. If so, you can justify a claim for the extra running costs you incur while working in this room. It is not as easy to work out your home office running costs when there is no separate office.

Expenses that you can claim for your contractor working from home expense will tend to comprise utility bills. Therefore, these will mainly include:

  • Heating.
  • Lighting.
  • Power supplies.
  • Some cleaning costs might be ok too.
  • Insurance might also be ok if the cover includes the equipment such as computers and other electronic devices and you use these in the business.

Many think they may be able to claim a proportion of their rent or mortgage or even part of the mortgage interest. However, these costs are not allowed, as mentioned earlier, because you would incur these costs whether you worked from home or not. 

HMRC guidance 

Recent history and the use of home as office allowance (UK)

Before the end of 2005, there was no benchmark for you if you were using your home as an office.  Neither the Inland Revenue (now HMRC) nor accountants had any guidance as to what proportion or absolute amounts of running expenses they could regard as acceptable when making a claim for use of home as office. Separate meters would be required to measure the amount of energy a business uses in the activities at home.

Cynically, we suppose, use of home allowance claims were made as high as the claimants dared. Perhaps in the hope that HMRC would not challenge their claims at all. Alternatively, if HMRC challenged them, then the claim could be justified. 

HMRC guidance around using your home as an office tax relief

When we investigate how much can I claim for using my home as an office (UK), let’s first look at the recent history. In early 2006, HMRC issued a bulletin about home office use. We paraphrase, “in recognition of the increasing occurrence of people carrying out their work from their homes, HMRC will not seek to challenge a claim towards home running expenses up to £3 per week”. Basically, this is a flat rate amount that one can claim in respect of use of home as office.

Subsequently, the amount allowable for your contractor working from home expense was increased to £4 per week, which stayed in place for many years up to March 2020. The amount then increased to £6 per week from 6 April 2020, just after the start of the recent pandemic. Subsequently, the amount you can claim for the use of the home as office allowance 2021/22 is £6 per week. In the following year, the HMRC use of home as office allowance 2022/23 and 2023/24 is still a weekly amount of £6. Therefore, the working from home allowance 2022/23 and 2023/24 is £6 per week or £26 per month.

Therefore today, if you like it or not, HMRC has its benchmark for use of home as office (£6 per week). On an annual basis, this equates to a working from home tax rebate of £312.

A justification exercise 

A claim for use of home as office allowance 2021/22 and 2022/23 or 2023/24 at an amount higher than the benchmark will need some scientific justification, and it will also need some evidence to support this:

  • As a starting point, as a starting point for your use of home expenses for limited company purposes, you could tally up the costs for some time before the business use at home starts. You can then compare these with costs for a similar period after the business has commenced. As a result, will this then be evidence?
  • On the other hand, you can take a tally of the appropriate expenses for a period of time. You can then divide the cost by the number of rooms in the home (one being the room you use for the business). You can then adjust the amount, up or down, as required. The claim will also depend on your time in the dedicated office room. You can then compare this with the time you spend in the rest of the house.

What’s more, perhaps you can take some energy that the office equipment consumes in calculating your use of home as office allowance 2021/22, 2022/23 and 2023/24. Indeed, a justification exercise may not be easy to put together, and contentions may be difficult to defend. The extra tax you save might not make a claim cost-effective. Not being cost-effective will also be the case if you incur professional fees in any detailed breakdown or later defence of the claim.

Advisory rate for use of home allowance 2022, 2023 and 2024 -HMRC’s rate when working from home

Unless a business owner has strong feelings to the contrary and wishes to justify a higher claim for working from home, we believe claims henceforth should be only the pre-agreed £6 per week.

If you think you can justify a higher amount than the £6 per week in respect of use of home as office, e.g., in a scenario where you use your home exclusively for work or work from home most of the time, you should prepare yourself to perform a justification exercise. Such an exercise is explained above.

If you claim an amount for using your home for business reasons and HMRC deems this excessive, the payment will be subject to National Insurance for the employer and Income Tax for the employee. 

Other considerations

Simplified expenses -if you are self-employed 

You can use the simplified expenses option as a working from home tax rebate if you are:

  • Self-employed; and
  • Work for 25 hours or more a month from home.

You can claim the rates below as a work from home tax rebate for how many hours you work at home each month. However, it is key to note that these rates are for self-employed people rather than directors of limited companies.

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

Use your home broadband/phone for business reasons while working from home

While you are working from home, you will more than likely be using the internet. Moreover, you may receive business calls while working or need to make them yourself. Therefore, you will, in most cases, also be able to make claims for your business phone calls and broadband usage. 

Renting a separate office

If you rent a separate office or work unit away from your home, you can claim for the expenses that relate to this:

  • Rent.
  • Business rates.
  • Utility costs.
  • Phone and broadband costs.

As with any business expenses, you should ensure that contracts and bills are in your company’s name rather than your personal name. 

Final thoughts

To sum up, as time passes, more and more business-type people work from home. If you want to work out how much it costs you to do this, you will need to make a comparison. When you calculate your working from home allowance 2022/23, you will look at the overall costs. Therefore, to work out your claim for HMRC use of home as office allowance 2022/23 and 2023/24, you can compare the current costs against the original expenses before starting your business. As a result of claiming to use your home as an office, either as a company or self-employed person, you will receive tax relief.

In most cases, limited company contractors and small business owners will stick to the allowable fixed rate of £6 per week as a claim for use of home as office when they use their home for business purposes. That is unless they spend much more than the occasional time working from home. Examples here could include where you work several days per week from home or if you run various computers at home at the same time.

Finally, if up to now, you have not yet been claiming for your use of home allowance you can claim for this now and in future. In addition, you could also claim for previous recent tax years.
