Homeworking costs for the self-employed

If you are self employed and work from home this factsheet will summarise what homeworking costs you can claim for tax purposes.

Self-employed and working from home? Some of the costs of the home can be claimed against tax and, in some cases, these costs may be considerable. We set out types of costs that may be relieved here but at BRM, we can advise on maximising the relief due to you if you live in the London area.

Over the last ten years technology has advanced massively. It was not so long ago that mobile phones were the size of a brick. Now emails and the internet can be accessed on the move. However, whilst technology has moved on, travelling has become more and more difficult. Homeworking has become the answer for many but how have the tax rules kept up with these changes?

Your status is important

The tax rules differ considerably depending on whether you are self-employed, as a sole trader or partner, or whether you are an employee, even if that is as an employee of your own company. One way or the other though, if you want to maximise the tax position, it is essential to keep good records. If not, HMRC may seek to rectify the tax position several years down the line. This can lead to unexpected bills including several years' worth of tax, interest and penalties.

This factsheet focuses on the position of the self-employed.

Wholly and exclusively

The self-employed pay tax on the profits that the business makes or their share of those profits. So, the critical issue is to ensure that costs incurred can be set against that profit. For day to day overheads, those costs generally have to be incurred 'wholly and exclusively' for the purposes of the trade to be tax deductible. What does this really mean in practice? Well, HMRC have issued a lot of guidance on the matter which is summarised below.

Use of the home

If the self-employed carry on some of their business from home, then some tax relief may be available. HMRC accept that even if the business is carried on elsewhere, a deduction for part of the household expenses is still acceptable provided that there are times when part of the home is used solely for business purposes. To quote:

'If there is only minor use, for example writing up the business records at home, you may accept a reasonable estimate without detailed enquiry.'

So that there is no confusion, wholly and exclusively does not mean that business expenditure has to be separately billed or that part of the home must be permanently used for business purposes. However, it does mean that when part of the home is being used for the business then that is the sole use for that part at that time.

HMRC accept that costs can be apportioned but on what basis? Well, if a small amount is being claimed then HMRC will usually not be too interested. In fact, HMRC seem to accept that an estimate of a few pounds a week is acceptable. However, if more is to be claimed then HMRC suggest that the following factors are considered:

  • the proportion in terms of area of the home that is used for business purposes
  • how much is consumed where there is a metered or measurable supply such as electricity, gas or water and
  • how long it is used for business purposes.

What sort of costs can I claim for?

Generally, HMRC will accept a reasonable proportion of costs such as council tax, mortgage interest, insurance, water rates, general repairs and rent, as well as cleaning, heat and light and metered water.

Other allowable costs may include the cost of business calls on the home telephone and a proportion of the line rental, in addition to expenditure on internet connections to the extent that the connection is used for business purposes.

So how does this work in practice?

As already mentioned, if there is a small amount of work done at home, a nominal weekly figure is usually fine but for substantial claims a more scientific method may be needed.

Example

Andrew works from home and has no other business premises. He uses a spare room from 9am to 1pm and then from 2pm until 6pm. The rest of the time it is used by the family. The room represents about 10% of the total area of the house.

The costs including cleaning, insurance, council tax and mortgage interest are about £8,000. 10% = £800 and 8/24 of the use by time is for business, so the claim could be £267.

Electricity costs total £1,500, so 10% is £150 of which 8/24 = £50.

In addition, a reasonable proportion of other costs such as telephone and broadband costs would be acceptable.

The key to Andrew's claim will be that he keeps the records to prove the figures and proportions used.

Equipment costs

For self-employed businesses, the depreciation of assets is covered by a set of tax reliefs known as capital allowances. For equipment at home, such as a laptop, desk, chair, etc, capital allowances may be available on the business proportion (based on estimated business usage) of those assets. So, if Andrew uses his laptop solely for business, the whole cost will be within the capital allowances rules.

What about travel costs?

Another consequence of working from home is the potential impact on travel costs. The cost of travelling from home to the place of business or operations is generally disallowed, as it represents the personal choice of where to live. The fact that the individual may sometimes work at home is irrelevant.

Where an individual conducts office work for their trade does not by itself determine their place of business, so although many may be able to claim tax relief for the costs of working from home, far fewer will be able to claim travel costs of going to and from their home office.

Of course, this principle presupposes that there is a business or operational 'base' elsewhere from which the trade is run. Normally, the cost of travel between the business base and other places where work is carried on will be an allowable expense, while the cost of travel between the taxpayer's home and the business base will not be allowable.

However, where there are no separate business premises away from the home, travel costs to visit clients should be fully allowable. The crux of the matter is where the business is really run from.

And finally...

Capital gains tax contains a tax exemption for the sale of an individual's private home, known as principal private residence relief (PPR). Where part of the dwelling is used exclusively for business purposes, PPR relief will not apply to the business proportion of the gain. However, HMRC make clear in their guidance that 'occasional and very minor' business use is ignored.

Be reasonable

As you can see, all things are possible but the key is to be clear about the rules, keep good records and be sensible about how much to claim.
