What Expenses Can a UK Limited Company Claim?
Running a UK limited company comes with many costs, from accounting software and office equipment to advertising and business travel. The good news is that many legitimate business expenses can be deducted when calculating your company's taxable profits.
Claiming the correct allowable business expenses can therefore help reduce the amount of Corporation Tax your company has to pay.
But what expenses can a UK limited company actually claim?
For Corporation Tax purposes, business expenses generally need to meet the relevant HMRC rules. A key principle for many expenses is that they must be incurred wholly and exclusively for the purposes of the company's trade.
Simply paying for something using the company bank account does not automatically make it tax deductible.
Personal expenses and costs that do not meet the relevant tax rules may need to be treated differently.
Depending on your company's activities and circumstances, allowable expenses may include:
Everyday costs associated with running your business may be deductible, including:
Your company may be able to obtain tax relief for equipment required to operate the business, such as:
Some purchases may be treated as capital expenditure and qualify for capital allowances rather than being deducted as an ordinary expense.
Professional services used for legitimate business purposes can often be claimed, including:
The tax treatment can depend on the nature and purpose of the professional service.
Marketing is an important expense for many UK companies.
Qualifying costs may include:
These costs generally need to relate directly to promoting the company's business.
Insurance purchased for business purposes can potentially be claimed, including:
Qualifying business travel costs may include:
However, normal commuting between your home and a permanent workplace is generally not treated as qualifying business travel.
Special rules can apply to temporary workplaces and directors who work at different locations.
A limited company may generally deduct qualifying employment costs, including:
Salary payments should be properly recorded and operated through payroll where required.
Many businesses now rely heavily on online services.
Potential expenses can include:
The subscription should be used for legitimate business purposes.
Potentially, yes.
If you work from home as a director or employee of your limited company, certain additional household costs may potentially be reimbursed by the company under HMRC's rules.
There are specific conditions governing home-working expenses, so directors should check the latest HMRC guidance before claiming substantial household costs.
Ordinary meals are generally personal expenses.
However, reasonable food and subsistence costs may sometimes be allowable when they form part of qualifying business travel.
Whether a meal qualifies depends on the circumstances surrounding the journey and the relevant HMRC rules.
Vehicle expenses can be more complicated.
Depending on the circumstances, a company may potentially claim costs associated with:
However, company vehicles can also create Benefit in Kind tax implications when they are available for private use.
Different tax treatment can apply depending on the type of vehicle, emissions and how it is used.
This is an area that often causes confusion.
Your company can pay for certain business entertainment, but client or business entertainment is generally not deductible when calculating taxable profits for Corporation Tax purposes.
There are different rules for some forms of staff entertainment, subject to specific conditions.
You should not simply claim personal purchases as business expenses.
If your company pays a personal expense for a director, it may need to be treated as a:
The correct treatment depends on the circumstances.
Keeping your personal and company finances separate can make accounting and tax reporting much easier.
Keeping accurate records is essential.
Your company should retain appropriate evidence of its business expenses, such as:
These records help support the figures included in your company's accounts and Corporation Tax calculations.
Allowable expenses can reduce the company's taxable profit.
For example, imagine a company generates:
£100,000 in business income
and has:
£30,000 in allowable business expenses
Before considering any other tax adjustments, this could leave:
£70,000 in profit
Corporation Tax would then be calculated based on the company's taxable profits after taking account of applicable tax rules, deductions, allowances and reliefs.
This is why correctly recording legitimate business expenses is so important.
Some expenses may not be deductible for Corporation Tax purposes or may be subject to special rules.
Examples can include:
Capital expenditure may also be treated differently from normal day-to-day business expenses.
Tax rules can change, and whether an expense qualifies can depend heavily on the circumstances.
Before claiming an unusual or substantial expense, check the latest official HMRC guidance on GOV.UK.
This is particularly important for expenses involving company cars, working from home, travel, entertainment, benefits, mixed personal and business use, and large equipment purchases.
A UK limited company can potentially claim many of the legitimate costs of operating its business, including office expenses, software, equipment, accounting fees, advertising, insurance, staff costs and qualifying business travel.
The important point is that an expense does not become tax deductible simply because it was paid by the company.
It must meet the relevant tax rules.
Keeping accurate records, retaining receipts and invoices, and correctly categorising company expenses can help ensure that your business claims the tax deductions it is entitled to while remaining compliant with HMRC requirements.
