Understanding what expenses a limited company can legitimately claim is one of the most important parts of running a business in the UK. It is also one of the areas where I see the most confusion, even among directors who have been trading for years. Many people assume there is a definitive checklist of expenses that are always allowed or always disallowed. In reality, it is more nuanced than that.

When I advise limited company directors, I always start with the same principle. An expense must be incurred wholly and exclusively for the purposes of the business. That principle underpins everything that follows and it is how HMRC ultimately assesses whether something is allowable or not.

In this guide, I will walk through a comprehensive limited company expenses list, explain what is usually allowable, where restrictions apply, and where directors need to be careful. This is written from a practical UK perspective and reflects how expenses work in real businesses rather than just theory.

How to use this limited company expenses list

Before diving into the list itself, it is important to understand how to use it properly. This is not a list of loopholes or guarantees. It is a guide to common expense categories and how they are typically treated.

Every expense still needs to meet three basic tests:

• It must be for business purposes

• It must not be primarily personal

• It must be reasonable in the context of the business

Where an expense has both business and personal elements, only the business portion is allowable.

Staff wages and employment costs

Employment costs are some of the most straightforward and widely claimed expenses for limited companies.

These usually include:

• Gross wages and salaries

• Employer National Insurance contributions

• Employer pension contributions

• Statutory payments such as sick pay or maternity pay

• Recruitment agency fees

As long as staff are genuinely employed and paid through payroll, these costs are normally fully allowable.

Director salaries

Director salaries are also allowable expenses.

This includes:

• Gross salary

• Employer National Insurance

• Employer pension contributions

The salary should reflect the work performed. While HMRC does not impose a strict limit, excessively high salaries without commercial justification can attract attention.

Office and premises costs

If your company operates from commercial premises, the associated costs are usually allowable.

Common examples include:

• Office rent

• Business rates

• Electricity and gas

• Water

• Cleaning

• Security services

These costs must relate to business premises rather than personal living space.

Working from home expenses

Many limited companies operate partly or fully from a director’s home.

In these cases, the company can usually claim a contribution towards household costs, such as:

• Electricity and gas

• Internet

• Phone

• Heating

The claim must be reasonable and proportionate. Some companies use a fixed monthly amount, while others calculate a percentage based on space and time used.

Professional fees and advisory costs

Professional services are a common and legitimate business expense.

Allowable costs usually include:

• Accountancy fees

• Bookkeeping services

• Payroll services

• Legal advice related to the business

• Business consultancy fees

Personal legal or tax advice for directors is not usually allowable unless it directly relates to company matters and is structured correctly.

Marketing and advertising expenses

Marketing costs are generally allowable, provided they promote the business.

Examples include:

• Website design and hosting

• Online advertising

• Social media advertising

• Print advertising

• Branding and logo design

Client entertaining is not allowable, even though it may feel like marketing. This distinction is important.

Telephone, mobile, and internet costs

Communication costs are commonly claimed and usually allowable.

This can include:

• Business landlines

• Mobile phone contracts

• Internet services

• VoIP systems

If a phone or internet connection is used privately as well as for business, the private portion should be restricted.

Travel expenses

Travel expenses are allowable where the journey is wholly and exclusively for business purposes.

Common allowable travel costs include:

• Train fares for business travel

• Bus and underground fares

• Taxis for business journeys

• Flights for business trips

• Hotel accommodation for business travel

Ordinary commuting from home to a permanent workplace is not allowable.

Mileage and vehicle expenses

Vehicle expenses depend heavily on how the vehicle is owned and used.

If a director uses their own vehicle for business, the company can usually pay mileage at HMRC approved rates.

If the company owns or leases the vehicle, allowable costs may include:

• Lease payments

• Insurance

• Repairs and servicing

• Road tax

Private use must be dealt with separately, often through benefit in kind rules.

Fuel costs

Fuel costs are allowable only for business journeys.

If the company pays for private fuel, this usually creates a taxable benefit unless the cost is reimbursed by the individual.

Good mileage records are essential in this area.

Subsistence and meals

Meals are allowable only in specific circumstances.

Allowable situations include:

• Meals during overnight business trips

• Subsistence while travelling to temporary workplaces

• Meals as part of long business journeys

Everyday lunches or food eaten while working late are usually disallowable.

Training and professional development

Training costs are allowable where they relate to maintaining or improving existing skills used in the business.

Examples include:

• Refresher courses

• Professional qualifications relevant to the role

• Continuing professional development

Training that prepares someone for a completely new trade is usually disallowed.

Business insurance

Insurance premiums related to the business are generally allowable.

This includes:

• Public liability insurance

• Employers’ liability insurance

• Professional indemnity insurance

• Commercial vehicle insurance

Personal insurance policies are not allowable.

Software and subscriptions

Software used for business purposes is usually allowable.

Examples include:

• Accounting software

• Design software

• CRM systems

• Project management tools

• Industry specific platforms

If software is used partly for personal reasons, the claim should be restricted.

IT equipment and office equipment

Computers, laptops, printers, and office furniture are common business purchases.

These are usually treated as capital items rather than day to day expenses and may qualify for capital allowances instead of being deducted in full as expenses.

Small items with a short lifespan may be treated as revenue expenses.

Stationery and consumables

Everyday consumables used in the business are generally allowable.

This includes:

• Paper and printing

• Ink and toner

• Office supplies

• Small tools and equipment

These expenses are rarely challenged provided they are reasonable.

Bank charges and finance costs

Financial costs related to running the business are usually allowable.

Examples include:

• Bank charges

• Overdraft fees

• Interest on business loans

• Merchant fees

Fines and penalties are not allowable, even if they arise from business activity.

Renting equipment and machinery

Rental costs for equipment used in the business are generally allowable.

This includes:

• Machinery hire

• Tool rental

• Vehicle hire for business use

These costs are often easier to manage than ownership from a tax perspective.

Staff welfare and benefits

Certain staff welfare costs are allowable.

Examples include:

• Staff uniforms

• Protective clothing

• Staff training

• Staff social events within limits

Client entertaining remains disallowable.

Clothing and uniforms

Clothing is only allowable where it is:

• A genuine uniform

• Protective clothing required for work

• Branded clothing that clearly identifies the business

Everyday clothing is not allowable, even if worn only for work.

Gifts and promotional items

Gifts to clients are usually disallowable, with limited exceptions for low value promotional items that meet strict conditions.

Staff gifts are usually allowable and may fall under trivial benefit rules if conditions are met.

Entertaining expenses

Client entertaining is disallowable for Corporation Tax purposes.

This includes:

• Meals with clients

• Drinks and hospitality

• Event tickets

Staff entertaining may be allowable if it meets exemption criteria.

Fines and penalties

Fines and penalties are always disallowable.

This includes:

• Parking fines

• Late filing penalties

• Regulatory penalties

These costs must be added back when calculating taxable profits.

Director’s loan account expenses

When personal expenses are paid by the company, they are often posted to the director’s loan account rather than treated as allowable expenses.

This can create tax consequences if not managed carefully.

Record keeping for expenses

Good record keeping makes expense claims far easier and safer.

I always advise companies to keep:

• Receipts and invoices

• Clear descriptions of expenses

• Mileage logs

• Expense policies

This evidence is critical if HMRC ever reviews the accounts.

Common mistakes I see with expense claims

From experience, the most common issues include:

• Claiming personal expenses

• Overclaiming home working costs

• Ignoring private use adjustments

• Treating entertaining as advertising

• Poor documentation

These mistakes often lead to tax adjustments and unnecessary stress.

Why professional advice matters

Expense rules are not just about what you can claim, but how you claim it.

An accountant helps by:

• Reviewing expense categories

• Identifying disallowable costs

• Advising on grey areas

• Protecting you during HMRC reviews

In my experience, conservative and well supported expense claims always outperform aggressive ones in the long term.

Final thoughts

A limited company expenses list is a useful reference, but it should never replace judgement. The real test is not whether an expense appears on a list, but whether it genuinely relates to running the business.

When expenses are claimed carefully, supported by records, and reviewed regularly, they reduce tax efficiently and safely. When they are claimed based on assumptions or hearsay, they often create bigger problems later.

If there is one guiding principle to remember, it is this. If you would not have spent the money without the business, and it can be justified clearly, it is usually allowable. When there is doubt, asking the question early is always the smartest move.
