Allowable Expenses Limited Company: Everything You Need to Know 


As a limited company contractor, you’re allowed to claim expenses for costs that your business incurs. In order for them to be deemed allowable, they must be wholly and exclusively for the benefit of the business, and not personal costs. These are deducted from your income when calculating your taxable profits, meaning that you only pay Corporation Tax on what’s left after these expenses are subtracted. 


This reduces your taxable amount, reducing how much you need to pay. It’s one of the main limited company benefits, but you need to make sure you follow HMRC’s guidelines about making claims. For example, the expense must be necessary and directly related to the business, and you must retain proof - for example, invoices or receipts - to show what’s been spent, where and when. It’s also important to remember that the expense can’t have a dual purpose, unless you can clearly show what portion of the expense is for business use.


Why Allowable Expenses Are One of the Best Limited Company Tax Benefits

There are a lot of limited company tax benefits, but there’s no denying that claiming allowable expenses is by far one of the best. Limited companies are taxed differently than sole traders or partnerships, and allowable expenses are a big advantage. Not only do they reduce Corporation Tax, but they improve cash flow, giving you more working capital. This makes it a lot easier to invest, grow and innovate, as you have the money there to use. It’s still within the business, rather than being used to pay tax. By keeping more profit, you can grow your business faster.


There’s a lot to think about when it comes to claiming allowable expenses, and many contractors don’t claim everything they’re entitled to. This is often due to fear of getting things wrong, triggering an HMRC investigation or misunderstanding the rules and incurring costs. But, with clear documentation and a good understanding of the allowable expenses guidelines, you can maximise your claims confidently.

What Limited Company Expenses Can You Claim?


There are a lot of tax-deductible expenses you can claim as a limited company contractor, and the exact expenses you have will depend on the type of work you do. Some commonly claimed expenses include:



• Business Travel - This includes train fares, taxis, flights, mileage, parking and other costs related to travelling to a temporary place of work. 

• Accommodation - You can claim for hotels or short-term rentals when you're staying away from home for business. The accommodation must be necessary and reasonable.

• Subsistence - This includes meals and refreshments you buy while travelling for work. You can’t claim meals consumed during your normal daily routine or at your usual workplace, only when you’re travelling for business.

• Home Office Costs - You can either claim a flat rate or a proportion of your household bills, based on the space and how long you used them for work purposes.

• Office Rent - If you rent a dedicated business premises, such as an office outside of your home, the rent and associated costs are allowable expenses.

• Office Supplies - This includes everyday items like printer ink, stationery, postage and notebooks used exclusively for business purposes. You can also claim for computer equipment, including laptops and monitors.

• Software and Subscriptions - You can claim for software that supports your work, such as Microsoft 365, Zoom, Dropbox and project management tools.

• Accountancy Fees - A lot of contractors use an accountant, and cost you pay an accountant for 

• managing company accounts, tax returns, payroll and compliance are tax-deductible.

• Marketing and Advertising - Costs like website design and maintenance, social media ads, business cards, flyers and branded merchandise are allowable.


Not All Costs Are Limited Company Allowable Expenses

Finding out that you can claim limited company expenses is a game-changer, but don’t let your imagination run wild, as not all costs are allowable. Though many business costs are deductible, some are either fully or partially disallowed, such as:


• Client Entertainment - If you’re taking clients to dinner, sports events or buying them gifts, you need to know that the costs can’t be claimed back. These are not allowable for Corporation Tax purposes. You can still pay through your company, but you won’t get any tax relief.

• Everyday Clothing - Only uniforms or protective clothing specific to your role are claimable. Suits, shirts and other regular clothing are not allowable, even if you only wear them for work.

• Fines and Penalties - You can’t claim for fines and penalties, regardless of whether they were incurred as part of business trade. This includes parking fines, HMRC penalties and legal penalties.

• Commuting Costs - Though you can claim travel expenses if you have to go elsewhere for work, commuting costs aren’t allowable. Travel from home to a regular, permanent workplace doesn’t make the cut. Only journeys to temporary workplaces are deductible, such as visiting clients.

Can You Claim Limited Company Entertainment Expenses?

There’s a lot of confusion about limited company entertainment expenses, and it’s a bit of a grey area that catches many contractors off guard, and making mistakes isn’t uncommon. There are certain limited company entertainment expenses that can be claimed, such as staff entertainment. But, only if it’s an annual event - for example, a Christmas party - and open to all employees. The cost must be £150 or less per person, per year. If you go over the limit, the entire amount becomes a benefit in kind, and it’s no longer tax deductible for you as the limited company director.


A lot of contractors make the mistake of assuming that client entertainment can be claimed as an allowable expense, but that’s not the case. Business entertaining of clients or prospects is not tax-deductible, including meals, drinks, event tickets and hospitality. Regardless of who you’re entertaining and how you’re entertaining them, the cost isn’t tax-deductible. 


What Are Limited Company Trivial Benefits?

If you’ve done any research into allowable expenses for limited companies, you might have come across trivial benefits. Trivial benefits allow you, as a limited company director, and any of your employees to receive small, non-cash gifts on a tax-free basis. As long as certain conditions are met, you’re entitled to trivial benefits. These can range from a bottle of wine, to flowers, chocolates or theatre tickets.


To qualify, the benefit must cost £50 or less, not be cash or a voucher that can be exchanged for cash, and not be a reward for work performance. As a director, you can give yourself multiple trivial benefits each tax year, but there’s an annual cap of £300 for directors of close companies. This means any company run by five or fewer shareholders, which yours likely is. As is the case with all tax benefits, make sure you keep accurate records, especially if you’re giving multiple gifts throughout the year.


Our Top Tips for Maximising Allowable Expenses as a Limited Company Contractor

  • Use a Specialist Accountant - With so much going on as a limited company contractor, it’s a good idea to use a limited company accountant when it comes to maximising expenses. Generalist accountants are qualified, but they might miss industry-specific claims, so choose someone who understands contractor accounting.
  • Digitise and Organise Receipts - You can’t claim limited company expenses without proof, so make sure to organise receipts. It’s a good idea to digitise everything, as paper receipts fade, get lost and rarely stay organised.
  • Separate Personal and Business Finances - If you have your personal and business finances mixed together in one account, things can quickly get confusing. It’s important to use a dedicated business bank account, which clearly shows what has been spent, where and when. Mixing expenses complicates bookkeeping, making mistakes more likely.
  • Review Expenses Regularly - Don’t wait until the end of the year to review all of your expenses, as there could be unexpected expenses that you’d forgotten all about. Review your transactions monthly or quarterly to catch missed claims early. You need to make sure you’re claiming for everything that’s allowable, and you’re not claiming for anything HMRC would frown upon.
  • Make Use of Flat Rate Expenses - If it’s simpler, make use of Flat Rate Expenses, especially for use of home or personal vehicles. HMRC allows flat rate claims instead of calculating the exact usage, making the expense easier to track. 
  • Deduct Business Insurance - Don’t forget to deduct business insurance when you’re organising your expenses. You can claim a full tax deduction on all business-related insurance, including professional indemnity insurance, public liability insurance and employers’ liability insurance.


At Go Limited, we know that allowable expenses is a complicated area, and it’s something a number of contractors find daunting. But, with our help and expertise, you’ll be maximising your expenses, claiming more and saving more before you know it.

Limited Company Allowable Expenses: FAQ (UK)

If you run a limited company, it’s important to know which expenses you can claim. This helps you reduce your tax bill and stay compliant with HMRC rules. Below are common questions people ask — answered clearly and simply.


How do I put motor expenses through the books for a limited company?

You can claim motor expenses in one of two ways:


If the company owns the vehicle, you can claim costs like:

  • Fuel
  • Insurance
  • Repairs and servicing
  • Road tax
  • Lease or finance payments


If you use your own car, claim mileage instead:

  • 45p per mile for the first 10,000 miles (25p after that)
  • No need to track fuel or running costs
  • Keep a mileage log (date, journey, reason, miles)


Commuting between home and your regular office is not claimable — but travel to clients or job sites is.



What motor expenses are allowed for a limited company?

Allowed expenses include:

  • Mileage (if using your personal car)
  • Fuel (if using a company car)
  • Car insurance (business use only)
  • Repairs and maintenance
  • Parking and tolls (business journeys only)


You can’t claim:

  • Personal trips
  • Parking fines
  • Everyday commuting


Can I deduct interest from a car loan through my limited company?

Yes — but only if:

  • The loan was taken out in the company’s name
  • The car is used only for business, or mostly for business


You can usually claim the interest on the loan (not the full repayment). Keep good records to show it’s a business cost.


What expenses can I claim for working from home?

If you're working from home, you can claim:


Option 1: Flat rate

  • Claim £6 per week (no receipts needed)
  • Simple and accepted by HMRC


Option 2: Actual costs

Claim a portion of:

  • Electricity
  • Heating
  • Internet
  • Rent or mortgage interest (in some cases)


For example: If your home has 5 rooms and you use one just for work, you can claim 1/5 of your bills (adjusted for time used).


You can also claim:

  • A desk and chair
  • Office supplies
  • Business phone calls


What does 'use of home expenses' mean for a limited company?

This means claiming part of your home running costs as a business expense.


There are two ways to do it:

Simple method: Claim £6/week without paperwork

Detailed method: Work out a fair portion of your bills (based on space and time used)


Some directors also set up a rental agreement between themselves and their company. This needs to be done carefully and may require advice from an accountant.

However, the tax responsibilities that come with running your own limited company are more complex than working as a sole trader, freelancer or under an umbrella company, which can complicate things ever so slightly.

By Vita Martin • April 15, 2026
Are Contractor Accountants Worth the Cost?  As a contractor, you’re probably used to doing a lot of things yourself.
