Capital vs revenue expenses: what limited companies get wrong

One of the most common sources of confusion for limited company directors is the distinction between capital and revenue expenses. The distinction matters because it affects how and when tax relief is given.

Many contractors assume that if something is “allowable”, it can be deducted in full from company profits straight away.

That is not always the case. In practice, HMRC treats some costs very differently, even where the item is clearly business-related.

In this guide, Michael McCullion, founder of Bright Ideas Accountancy, outlines the differences between capital and revenue expenses and why you should be cautious when dealing with mixed-use costs.

Capital vs revenue expenses – the basics

Revenue expenses are the ongoing costs of running your business. These are normally deducted in full from your company’s profits when calculating its Corporation Tax liability.

Capital expenses, on the other hand, relate to assets that are expected to be used by the business over a longer period.

Instead of providing an immediate tax deduction, tax relief is usually granted over time through capital allowances.

This is an accounting and tax distinction, not a judgment on the legitimacy of the expense.

Some common capital expenses that contractors misclassify

Some of the most common mistakes involve items that appear to be everyday business costs but that HMRC treats as capital assets.

Computer equipment and hardware

Laptops, desktop computers, monitors, servers, and similar equipment are typically treated as capital assets. Although they are essential for contract work, the cost is usually offset through capital allowances rather than recognised as an immediate expense.

This may come as a surprise to contractors, especially where the equipment is replaced frequently.

Vehicles and company cars

Cars purchased by the company are capital assets. The tax treatment depends on emissions, ownership and use, and does not work in the same way as routine running costs.

It is common for directors to assume the purchase price can be offset immediately, which is rarely correct.

Long-term business assets

Office furniture, specialist equipment, and other assets intended for long-term use are usually capital in nature.

These are included on the company’s balance sheet rather than being written off straight away.

Read more in our guide to the balance sheet and profit and loss account.

From an accounting perspective, it is important that the company has a policy it adheres to for capitalisation. This could be value-based (i.e., anything over £1,000) and/or time-based (anything with a useful life of more than 3 years).

Revenue expenses people wrongly treat as capital

The reverse mistake also occurs when ongoing costs are treated as assets, even though they should normally be expensed.

Software subscriptions and digital services

Most cloud-based software, online tools and subscription services are revenue expenses. They do not create a lasting asset owned by the company.

This includes many digital tools used for remote working and collaboration.

We cover some common examples in our guide to digital and remote working expenses.

Training and professional development

Training costs are normally revenue expenses where they relate to maintaining or updating existing skills. They are not usually capitalised, even if they benefit the business over time.

There are limits and exclusions, which we cover in our guide to claiming training costs via your limited company.

Marketing and promotion

Advertising, website maintenance, online promotion and similar costs are generally revenue expenses. They do not normally create a capital asset, even where branding has a long-term benefit.

See our guide to marketing and advertising expenses for practical examples.

The repair vs improvement trap

A particularly common grey area is the difference between a repair and an improvement.

Repairs that restore something to its original condition are usually revenue expenses. Improvements that significantly enhance or upgrade an asset are more likely to be treated as capital.

This issue often arises with home office arrangements, office refurbishments and rented workspace.

Personally owned assets transferred into the company

Another common area for mistakes is when directors transfer personally owned assets into their limited company.

Assets are typically transferred at market value rather than at the original purchase price. This can affect capital allowances, directors’ loan accounts, and, in some cases, Capital Gains Tax.

Our guides to transferring personal assets to your limited company, director’s loan accounts, and lending money to your company explain these mechanics in more detail.

Pre-trading costs and capital expenditure

Pre-trading rules allow certain costs incurred before incorporation to be treated as if they were incurred by the company. However, these rules do not convert capital items into revenue expenses.

Capital expenditure remains capital expenditure, even if incurred before trading begins. See more in our guide to pre-trading expenses.

Capital expenses, dividends and overdrawn positions

Misclassifying capital expenditure can have knock-on effects beyond Corporation Tax. Because capital items do not reduce profits immediately, they can affect the amount you can distribute as dividends.

This is a common cause of illegal dividends and situations in which directors later discover they have been overpaid.

Does IR35 change capital vs revenue rules?

IR35 does not alter the underlying distinction between capital and revenue expenses. The accounting treatment of costs remains the same.

What does change, where IR35 applies, is the extent to which certain expenses can be offset against taxable income.

This is covered in our guides to working inside and outside IR35, as well as the small company exemption.

This is why you need an accountant

For the uninitiated, the capital vs. revenue question can be far from obvious, especially where assets are involved or there is any mixed personal and business use.

If you have any questions about expenses in general, always talk to your accountant first; that’s what they’re there for!
