What expenses can I claim as a sole trader?

Answered 11 March 2026

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.

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’.

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]
