Running a business may seem easy, but it is not. It demands tax responsibilities and financial decisions. One wrong move and it can cost you expensive penalties. Fortunately, there is an effective way to protect your profits, and that is to claim expenses as a limited company. So, as a limited company, you can lower your taxable profits by claiming valid business expenses. This directly reduces your company’s Corporation Tax liability. However, you must know HM Revenue & Customs (HMRC) strict regulations on what counts as allowable expenses. If you add any incorrect expenses and claim them, you may face costly HMRC penalties and compliance audits. This comprehensive guide helps you understand what business expenses you can claim as a limited company. It also explains what records you need to keep and which expenses require particular care. What Are Allowable Expenses for Limited Companies? Before explaining how you can claim expenses as a limited company, let’s understand what limited company allowable expenses are. Allowable expenses are the costs that are related to running a business and are treated as necessary. These allowable business costs reduce the profit amount a company pays tax on. Keep in mind that there is no single list that makes every business cost automatically allowable for Corporation Tax. The correct tax treatment depends on the nature and purpose of the expense and how it is used. For many trading expenses, the relevant question is whether the expenditure is incurred wholly and exclusively for the company’s trade. However, different rules can apply to particular categories of expenditure. Here is the common limited company expenses list that you can deduct when calculating your taxable profit: Travel and the New Mileage Rates When you are travelling for business purposes, certain travel and related costs are allowable. If you want to claim expenses as a limited company, you need to keep accurate mileage records. Also, you should ensure that the costs qualify under HMRC rules. Business travel that qualifies as allowable expenses may include costs such as flights, train fares, taxis and accommodation. Ordinary commuting between a permanent workplace and a home is usually not considered an allowable business expense. Visit the official HMRC guidance to learn more about mileage rates for 2026/27. Office Expenses Office-related expenditure is a common cost that you can claim as a limited company. Depending on your company’s circumstances, this can include costs associated with purchasing items needed to run the office. However, some items, particularly certain equipment and other assets, may be treated as capital expenditure and dealt with under the capital allowances rules. When an expense has both personal and business elements, the tax treatment depends on the circumstances. When you claim expenses as a limited company, you may sometimes claim an identifiable business proportion of an expense. However, a cost with an inseparable dual purpose may not qualify for a deduction. Professional and Accountancy Fees You may use accountants, solicitors and other professional advisers to manage your business operations. When you use these services solely for your business, the associated costs may be deductible, subject to the relevant tax rules. Working from Home Costs From 6 April 2026, employees can no longer claim Income Tax relief from HMRC for additional household expenses when working from home. However, the removal of employee tax relief does not affect the separate rules allowing employers to make qualifying exempt homeworking payments where the relevant conditions are met. You can pay an employee £6 per week towards additional household expenses when they regularly work from home under an agreed homeworking arrangement, without requiring evidence of the actual costs. You may reimburse reasonable additional household expenses based on the actual costs incurred, provided you have supporting evidence. Furthermore, you can pay rent for an employee’s or director’s home. However, it creates complex tax and Capital Gains Tax (CGT) rules, especially if they use that space only for business. Software and Subscriptions If you rely on accounting software and are thinking if you can claim expenses as a limited company, the answer is yes. Modern businesses use accounting software, cloud storage, and other subscriptions. If a subscription is incurred for the company’s business, it can qualify as a deductible expense. However, if a service is used for both private and business purposes, the tax treatment depends on the circumstances. Advertising and Marketing Advertising and marketing expenditure can be an important part of running a business. Costs such as advertising campaigns and marketing services may qualify as deductible business expenses, provided they meet the relevant tax rules. Keeping supporting records can help you show the nature and business purpose of the expenditure, making it easy to claim expenses. How to Claim Expenses as a Limited Company? A limited company can claim business expenses with ease if it keeps accurate records and supporting evidence for each expense, such as invoices and receipts. You can pay qualifying business costs directly from your company bank account. Additionally, you need to make sure the expenditure has a genuine business purpose and is treated according to the relevant tax rules. You should include allowable revenue expenses in the company accounts when calculating taxable profit for Corporation Tax. What Expenses Can I Claim As a Director of a Limited Company UK? As a director, you may be able to have genuine business expenses reimbursed by the company, provided the expenses meet the relevant rules and are properly recorded. You may be able to claim genuine business expenses, such as qualifying business travel and mileage, business software, office costs, professional fees, and certain costs of working from home. Additionally, when you claim expenses as a limited company, remember that reimbursement and tax deductibility are related but separate considerations. What Expenses Cannot Be Claimed by A Limited Company? You must understand that not every business cost is deductible for Corporation Tax. Some expenditure is disallowed or restricted when calculating taxable profits, while other expenditure may receive tax relief under different rules. For instance, you cannot claim expenses
