Maximising allowable expenses for limited companies

Spending money on tax deductible expenses, lowers your company’s profits for tax purposes and therefore corporation tax liability.  

In this comprehensive guide, we will explore the categories of allowable expenses, provide insights on HM Revenue and Customs (HMRC) rules and compliance, and share strategies for maximising your deductible expenses. 

What are tax deductible expenses for limited companies? 

There is usually a difference between accounting profit and profits for corporation tax. This can be as a result of disallowable expenses. 

Expenses solely for business use can be included in the accounts and tax return of limited companies. Where expenses include a personal element, an adjustment must be made on the tax return, reducing allowable expenses. Furthermore, some expenses can’t be claimed at all on your company tax return. For example, capital costs such as the purchase of assets and legal costs in connection with capital costs. 

Allowable expenses must be wholly and exclusively incurred for business purposes.

Expenses can be paid through the company bank account, and costs paid personally can also be reimbursed by the company and included on the tax return where wholly and exclusively for the running of your business. 

For specific categories on what expenses your business can claim, see below. 

The importance of record keeping 

Maintaining accurate and comprehensive records of your expenses is crucial for claiming allowable expenses and ensuring compliance with HMRC regulations. You must retain your records as evidence for six years after the end of the accounting period. 

Implementing a robust record-keeping system is essential to keep your records organised and accessible. This could be a manual system or you can store records digitally in a safe, secure place. If you are uploading documents into your bookkeeping software, or storing them digitally, then you don’t need to keep the records elsewhere. You can dispose of the paperwork. 

It is important to have the evidence to demonstrate your records are correct and accurate, especially when it comes to whether payments are allowable expenses for your company. Should HMRC launch an investigation into your business, or a tax period having all the information to hand can help the investigation run smoothly. 

Strategies for maximising deductible expenses 

To maximise tax deductible expenses for your company, consider implementing the following strategies: 

• Plan your expenses carefully and ensure that they are wholly and exclusively for business purposes so that they are tax deductible. Preparing a budget at the start of the financial year helps you plan and monitor business expenses to ensure your financial results meet expectations. 
• Keep detailed records and store all relevant documentation as evidence for your records, should you need to look back on anything or provide additional information to a third party, such as HMRC. 
• Consult with an accountant to ensure that you are claiming all eligible expenses and complying with HMRC rules.
