What Expenses Can I Claim for My Limited Company?
- Update September 14, 2026
Are you leaving money on the table by not claiming legitimate limited company expenses in the UK? Many directors of a limited company often pay more tax than they should because they don’t fully understand what counts as allowable business expenses. HMRC rules can be tricky, but every pound you miss could mean a higher corporation tax bill or unnecessary personal costs.
Recent surveys suggest UK small businesses fail to claim tax relief on thousands of pounds in business expenses each year. Whether you’re a London startup working from a co-working hub or a Manchester manufacturer with a factory, knowing exactly “what can I claim as business expenses” is vital.
This guide is your comprehensive resource, covering everything from office costs and travel expenses to staff benefits and annual events. You’ll learn how to reduce your corporation tax liability legally and stay compliant with HMRC rules.
Limited Company Allowable Expense List
Office and Premises Expenses
Office costs are among the most common deductible items. For limited companies, these may include:
- Rent for commercial premises
- Utilities such as gas, water, electricity, and internet
- Cleaning, maintenance, and repairs
- Insurance (contents and liability)
- Security systems
- Business rates (though small businesses may qualify for relief)
If you work from home, you can claim a proportion of running costs such as heating, lighting, or even mortgage interest. The key is to calculate fairly and keep records. Remember, London offices usually cost far more than regional hubs, so proportionate claims vary.
Travel and Transport Expenses
When it comes to business trips, HMRC allows claims if they are wholly and exclusively for work. This includes:
- Mileage in a personal car (45p per mile for first 10,000 miles; 25p thereafter in 2024)
- Public transport fares
- Taxis and parking charges (business purposes only)
- Tolls and congestion charges for work journeys
- Overnight stays and meals during work travel (within reason)
Be careful: normal commuting between home and office is not allowable. International trips are claimable if they are work-related.
Staff and Employment Costs
As an employer, your limited company can deduct a wide range of staff-related expenses:
- Salaries and wages (including the director of a limited company)
- Employer’s National Insurance contributions
- Pension contributions
- Staff training and development courses
- Recruitment fees
- Protective clothing and health & safety gear
- Annual events- e.g., Christmas parties, up to £150 per head (including VAT) is exempt from tax
Professional Services and Subscriptions
Allowable business expenses also cover essential services:
- Accountancy and bookkeeping fees
- Legal or tax advisory services
- Professional memberships and industry subscriptions
- Software tools like accounting packages, CRM, or payroll
- Insurance such as professional indemnity
- Bank charges, overdraft fees, and loan interest
Marketing and Business Development
Your company can deduct costs spent on growth and promotion, such as:
- Website design, hosting, and ongoing updates
- Digital marketing (social ads, Google campaigns)
- Business cards, brochures, and stationery
- Trade shows and networking events
- Client entertainment (subject to restrictions)
- Gifts for clients (must be under £50 each and carry your logo)
Localised marketing also qualifies – for example, sponsoring a local football club in Birmingham or running print adverts in Manchester.
Equipment and Technology
Investments in tools and technology are deductible:
- Computers, laptops, and printers
- Office furniture (desks, chairs, storage)
- Machinery and specialist tools
- Mobile phone and business communication devices
In many cases, you can claim full relief under the Annual Investment Allowance (AIA). However, some items must be depreciated over time using capital allowances. Always assess whether to buy outright or lease.

Common Mistakes and Grey Areas
Directors often get caught out by these issues:
- Claiming for commuting as a business trip (not allowed)
- Mistaking staff entertainment for client entertainment (different rules)
- Trying to deduct normal clothing instead of uniforms
- Failing to separate personal use from business purposes for assets
- Claiming eye tests not linked to VDU use (only allowable if for work equipment use)
- Paying for fines and penalties – never deductible
Record Keeping and Documentation
To make your claims bulletproof:
- Keep digital or paper receipts for six years
- Log all mileage with dates and purposes
- Reconcile expenses with bank statements
- Ensure VAT invoices are valid if reclaiming VAT
- Stay compliant with Making Tax Digital rules
Cloud storage is often the safest option to manage documentation efficiently.
Regional Variations and Local Considerations
The UK has regional tax and cost differences that matter:
- London businesses face higher rent and salaries
- Scotland applies the Scottish Rate of Income Tax, which can affect directors who take part salary
- Northern Ireland has specific grants that reduce costs
- Local councils may treat home offices differently in business rates
Year-End Tax Planning with Expenses
Strategic timing can save tax:
- Bring forward expenses before year-end to cut the current year’s corporation tax bill
- Make large equipment purchases before 31 March to use full AIA
- Prepay rent, insurance, or subscriptions if cashflow allows
- Pay professional fees in advance to lock in deductions
When to Seek Professional Help
You should consult an accountant if:
- You are unsure about dual-purpose items like mobile phones or cars
- You have large capital investments
- You are facing an HMRC compliance check
- You manage multi-location or cross-border expenses
