How To Maximise Tax Deductions

Maximising Tax Deductions Through Expense Management

Regardless of the industry you work in or the services you provide, as a contractor it’s important that you make the most out of your earnings. After all, you’ve worked hard to grow your business, and it makes sense that you profit as much as possible. But, there are a handful of costs that come with running a limited company that hinder that, including paying tax. Of course, tax isn’t something that you can avoid altogether, but it is something that you can minimise. By maximising your tax deductions through expense management, you can make sure that all of your limited company allowable expenses are being claimed.



At Go Limited, we’ve seen a lot of contractors set up limited companies and then not make the most of allowable expenses. It doesn’t matter what type of business you run, you’re bound to have a number of tax deductions that you can use to reduce your tax bill. Trust us, it’s just a case of maximising those deductions, which is where expense management comes in.

How to Maximise Limited Company Tax Deductions


When you’re putting a lot of time and energy into growing your limited company, you’ll want to get as much out of your earnings as possible. This means making the most of your profits and reducing your outgoings, including your tax bill. When you set up a limited company for contracting, you have the benefit of being able to claim allowable expenses, which are costs related to the services that you provide. 


There are various expenses that are wholly and exclusively for business purposes and by maximising these, you can reduce your taxable income and keep more of your earnings in the business. 


  • Office Costs - Rent, utilities, business insurance, office furniture and office supplies can all be claimed as limited company tax deductions.


  • Travel and Accommodation - Business travel expenses such as mileage, train tickets, flights, hotel stays and subsistence costs are all allowable expenses for a limited company contractor. 


  • Professional Fees - Limited company contractors can claim accountancy fees, legal costs, and professional memberships as tax deductible, as long as they’re related to your industry.


  • Training and Development - Courses, certifications and workshops that enhance your business skills or contribute to professional growth are allowable expenses for a limited company.


  • Equipment and Software - Laptops, phones, business software subscriptions and even website hosting costs are limited company allowable expenses.


  • Advertising and Marketing - A lot of contractors forget about limited company allowable expenses related to advertising and marketing, such as website development, SEO, online advertising and business promotion.


  • Insurance - Business insurance such as professional indemnity, public liability and employer's liability insurance are limited company allowable expenses.


  • Subscriptions and Publications - Limited company allowable expenses include industry-related journals, trade publications and online subscriptions that help keep you informed and competitive.

The Importance of Accurate Record Keeping in Expense Management


If you want to maximise limited company tax deductions through expense management, you need to keep accurate, organised records. To claim tax deductible expenses as a limited company, you need to prove the expense to HMRC. HMRC requires proof of all business expenses, and you can’t claim deductions for costs that you don’t have evidence for. You can prove allowable expenses for a limited company by:


  • Keep All Receipts and Invoices - You need to keep all receipts and invoices related to business expenses, either physically or digitally, to prove what has been spent. Otherwise, there’s no way to show your limited company allowable expenses.


  • Use Accounting Software - There’s a lot that goes into expense management, but using cloud-based tax management software - like Xero and QuickBooks - can help to track and organise expenses. It’s a good way to see your limited company allowable expenses in one place.


  • Log Your Mileage Correctly - If you use a vehicle for business purposes and you want to claim mileage for business travel, you need to keep a detailed log of journeys. Make sure to dates, distances and purposes. This is especially important if you also use the vehicle for personal use.


  • Keep Personal and Business Finances Separate - It’s a good idea to have a dedicated business bank account, as this helps to ensure your financial records are clear. If your personal spending and business spending are together, it’s difficult to know which expenses were related to your business.


  • Regularly Review Expenses - It’s a good idea to conduct regular audits to ensure all eligible expenses are being claimed and any errors are corrected promptly. When you have a lot of limited company allowable expenses to organise, regular audits help you to find any mistakes before they become bigger issues.


By staying on top of record keeping and expense management, you reduce the risk of errors, whilst also maximising for allowable tax deductions.

  • Automating Bookkeeping - Accountancy services for a limited company can reduce manual data entry through cloud-based accounting solutions, making it easier to categorise and track expenses.


  • Expert Advice - Providing ongoing financial guidance enables a limited company accountant to ensure your tax efficiency and business profitability.

How Tax Works When You Set Up a Limited Company as a Contractor For a lot of contractors in the UK, setting up a limited company is the most flexible, professional and - if you do things the right way - tax-efficient way to work. 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. As a limited company contractor, you are both a company director and (usually!) a shareholder, which means tax applies at both company and personal levels. If you’re new to running a limited company, this will be a huge change to what you’re used to. At Go Limited , we know how important it is to understand how tax works when you set up a limited company as a contractor. In fact, it’s essential for staying compliant with HMRC and making informed financial decisions.

Are Contractor Accountants Worth the Cost?  As a contractor, you’re probably used to doing a lot of things yourself. You run your own business, manage your own workload and decide which projects to take on.
