What expenses can I claim as a sole trader?

Expenses a Sole Trader Can Claim
What the law says
The core statutory rule is found in s.34 ITTOIA 2005. No deduction is allowed when calculating trade profits for:
- expenses not incurred wholly and exclusively for the purposes of the trade, or
- losses not connected with or arising out of the trade
However, where an expense is incurred for more than one purpose, a deduction is still permitted for any identifiable part or proportion that is wholly and exclusively for trade purposes.
Revenue expenditure (day-to-day running costs) is generally allowable unless there is a specific statutory prohibition. Capital expenditure (e.g. improvements to property, purchase of long-term assets) is not allowable as a trading deduction, though capital allowances may apply separately.
Specific statutory disallowances include:
- Entertainment costs — disallowed by s.45 ITTOIA 2005
- Capital expenditure — disallowed by s.33 ITTOIA 2005
HMRC guidance / practice
HMRC's guidance confirms there is no comprehensive list of allowable and disallowable expenditure. The following categories are recognised as typically allowable:
✅ Common Allowable Expenses
| Category | Detail |
|---|---|
| Stock & materials | Cost of goods for resale and materials for manufacturing |
| Wages & NIC | Wages of employees and secondary National Insurance contributions |
| Rent | Rent paid to a landlord for business premises |
| Business rates | Rates and water rates on business premises (but not Council Tax as a personal liability) |
| Repairs | Repairs to business premises, plant and equipment |
| Telephone | Telephone charges |
| Travel & hotels | Travel and hotel expenses on business trips aimed at obtaining business |
| Renewals | Small items such as replacement tools, linen, crockery, cutlery |
| Insurance | Insurance of business buildings or contents |
| Theft losses | Losses due to theft by staff or members of the public |
| Sales promotions | e.g. trading stamps |
| Sundry expenses | Miscellaneous small payments |
| Pre-trading expenses | Revenue expenses incurred up to 7 years before trading starts, if they would have been allowable once trading commenced (s.57 ITTOIA 2005) |
🏠 Use of Home
Where part of a home is used solely for trade purposes, a proportion of household expenses (e.g. electricity, rent) is allowable. The trade-use portion of a single bill can be claimed even if the rest is private. However, a sole trader cannot charge a separate rent to their own trade — only the proportion of rent paid to the landlord attributable to the trade-use part is allowable.
🚗 Travel
Travel from home to a fixed place of work is generally not allowable. However, for itinerant traders (e.g. a jobbing builder travelling to multiple temporary sites), travel costs from home may be allowable where the home is genuinely the base of operations. Travel is disallowed where one purpose of the journey is to allow the trader to live away from their place of work, as this creates a duality of purpose.
❌ Key Disallowances
- Business entertainment (statutory disallowance under s.45 ITTOIA 2005)
- Capital expenditure (e.g. property improvements)
- Private/non-business expenditure
- Expenditure relating to non-trading income sources
💡 Trading Income Allowance
As an alternative to claiming actual expenses, a sole trader with turnover below £1,000 may instead claim the Trading Income Allowance rather than deducting actual expenses.
Important note: The allowability of any specific expense always depends on the particular facts. HMRC will examine whether the "wholly and exclusively" test is met on a case-by-case basis.

S57 Income Tax (Trading and Other Income) Act 2005 (ITTOIA 2005), S61 Corporation Tax Act 2009 (CTA 2009) The above legislation provides relief in respect of certain expenditure of a revenue nature incurred for the purposes of a trade, profession or vocation before it is commenced. The relief extends only to expenditure which: is incurred within a period of seven years prior to the commencement of the trade, profession or vocation, and is not allowable as a deduction in computing the profits of
For unincorporated businesses, the profits of a trade, profession or vocation (see BIM14010) are taxed as trade profits under S5 ITTOIA 2005. The trading profits of companies are taxed under S35 CTA 2009. To calculate those profits you need to determine: whether sums arising are taxable income of the trade, profession or vocation - see BIM15035 the time at which receipts or expenses should be recognised - see BIM31090 onwards, and what deductions are allowable in computing the profits - see BIM4
ole trader claiming Trading Income Allowance A sole trader prepares their accounts to 31 July. The accounts for the year 31 July 2020 show a turnover of £800. As their turnover is less than £1,000, they claim the Trading Income Allowance instead of actual expenses. The sole trader receives a SEISS payment of £2,500 in May 2020. They cannot offset any amount of the SEISS payment against the remaining £200 of the trading income allowance available and will be taxable on the entire SEISS payment in
The costs of travel to and from home and a place of work are not allowable where one of the purposes of the travel is to allow the trader to live away from their place of work. This is because such expenses do not satisfy the statutory test in S34(1)(a) Income Tax (Trading and Other Income) Act 2005 (for unincorporated businesses) and S54(1)(a) Corporation Tax Act 2009 (for companies) that to be allowable the expense must have been incurred ‘wholly and exclusively for the purposes of the trade’.
Part of the rent is an allowable expense when the home is rented and part is used solely for trade purposes. A sole trader cannot charge a separate rent to his or her own trade. This is because individuals cannot rent property to themselves. The allowable expense is the proportion of the rent paid to the landlord that is properly attributable to the part of the home being used solely for trade purposes. Where a partner charges rent for the use of their home by a partnership of which they are a m

Business accounts drawn up in accordance with generally accepted accounting practice provide the basis for determining the deductions allowable against trading income, subject to statute and case law. The broad test of whether an expense is deductible is whether it is a proper debit against trade receipts in computing the profits of that trade for that period. Subject to specific statutory provisions, the following will not be deductible: expenditure on capital account, or in connection with cap

The day to day running costs of a business (eg staff wages, purchase of trading stock, rent of business premises, and so on) are referred to as revenue expenditure. Revenue expenditure is sometimes described as circulating capital. This description reflects the fact that the capital in question leaves the owner’s possession (changes masters) to produce profit or loss. The capital may be considered as being ‘turned over’. In the process of turning over, profit or loss ensues. Unless there is a sp
Where an ‘itinerant’ trader’s base of operations is at their residence, you should allow the costs of travelling between the residence and the sites at which the trader works. An itinerant trader is one who travels from their home to a number of different locations for the purely temporary purpose at each such place of their completing a job of work, at the conclusion of which they attend at a different location. A typical example would be a jobbing builder. In the case of Horton v Young [1971]
The statute has, from the earliest days, included a rule restricting deductions to those incurred wholly and exclusively for the purposes of the trade. The words used have been subject to very little alteration over the years. The current form of words is in S34(1)(a) ITTOIA 2005 for unincorporated businesses and S54(1)(a) CTA 2009 for companies, which provide: In calculating the profits of a trade, no deduction is allowed for - expenses not incurred wholly and exclusively for the purposes of t
