Managing Taxes as a Contractor
Managing Taxes as a Contractor Within a Limited Company Structure
There’s been a lot of talk lately of the number of contractors who are deciding to set up limited companies, and we understand why. With so many benefits - including having more control over your income, taking advantage of allowable expenses and portraying a more professional image - it’s easy to see why setting up a limited company is such a popular route for sole traders, freelancers and contractors in the UK. But, it’s not without additional responsibilities.
When you’re a contractor working within a limited company structure, you need to manage your taxes. You’re not paid via PAYE, meaning you need to navigate the tax systems yourself. This can be complicated, but Go Limited is here to help.
How Does Limited Company Tax Differ from PAYE?
When it comes to deciding whether or not to set up a limited company as a contractor, it’s often tax that sways people into taking the plunge. That’s because there are a whole host of benefits that come with having a limited company structure to the way you work. When you operate through a limited company, your contracting business is considered a separate legal entity. This changes how you’re taxed, compared to being an employee under the PAYE (Pay As You Earn) system.
Under PAYE, income tax and National Insurance contributions (NICs) are automatically deducted from your salary by your employer. You don’t need to think twice about it, as it’s all handled for you. But, as a limited company contractor, you’re responsible for managing your own tax obligations. This might sound like a lot of hard work and administration, but there are clear advantages.
For example, as a contractor with a limited company, you can pay yourself through a mix of salary and dividends. Dividends are taxed at a lower rate than salary income, and are not subject to NICs. This keeps more of your hard-earned money in your pocket. You can also decide when and how to distribute business profits, giving more control over your income and tax liabilities. To put it simply, setting up a limited company can significantly reduce your total tax burden compared to being paid solely through PAYE.

Navigating Limited Company Tax Deductions as a Contractor
One of the main things you need to do as a contractor within a limited company structure is to navigate tax deductions. When you’re running a limited company, you have the ability to claim allowable business expenses, which reduce your taxable profits. These allowable expenses are costs that are wholly and exclusively incurred for the purpose of running your business. By claiming them, you reduce your taxable profits, and therefore reduce your tax liability.
There are a whole host of different limited company tax deductibles to take advantage of, and what you can claim will depend on the type of work you do and the expenses you have. Common examples include office supplies and equipment, business travel and accommodation, software and subscriptions, accountancy fees, professional training and marketing costs. You can even claim a portion of home office costs, if you regularly work from home.
By accurately tracking and claiming these expenses, you reduce your business’ profit and, in turn, your tax liability. However, you need to be able to prove what you’re claiming. You need to maintain good records and receipts to support your claims, as HMRC can ask for proof during an investigation.
Top Tips for Managing Tax Deductions as a Limited Company Contractor
- Keep Detailed Records - To make managing your taxes as simple and straightforward as possible, you need to keep detailed records. Maintain a well-organised system for tracking all of your business-related expenses, ensuring you log receipts and invoices, categorise expenses correctly and track VAT.
- Understand What Counts as an Allowable Expense - As we mentioned above, only expenses that are wholly and exclusively for business purposes are allowable. You can’t claim for personal costs, even if the purchase is somewhat related to your career. For example, you can claim for travel costs to client sites, but not for regular commutes. You can claim for phone and internet costs, but not for anything you use personally. If you claim home office costs, you have to determine what portion of those costs are related to business.
- Track Mileage Instead of Fuel Costs - A lot of contractors make the mistake of trying to claim fuel costs, rather than mileage costs. If you use your personal car for business travel, it’s often simpler to claim HMRC’s approved mileage rates, instead of trying to deduct fuel, insurance and vehicle maintenance costs.
- Use a Business Bank Account - It might initially seem easier to lump your business and personal expenses in together, but things can get confusing very quickly. Always keep business finances separate from personal ones, so you can clearly see which expenses have been spent where. A dedicated business account makes it easier to track expenses and avoids complications if HMRC ever decides to investigate your limited company.
- Don’t Forget Annual Costs - With a lot to manage as a limited company contractor, it’s not uncommon for things to fall through the net, including annual costs. When you’re managing your tax deductions and allowable expenses, include annual subscriptions or insurances. This includes professional memberships, business insurance premiums and website hosting.
- Work with a Specialist Limited Company Accountant - With so much to manage, one of the best things you can do for your taxes is work with a specialist limited company accountant. They can ensure you're claiming all allowable expenses correctly, help you to avoid common pitfalls and keep your tax position compliant, efficient and in line with HMRC regulations.

Sole Trader or Limited Company Tax: Which is More Cost-Effective?
When you’re managing taxes as a contractor, you need to weigh up the pros and cons of being taxed as a sole trader versus a limited company contractor. The answer largely depends on your income level, industry and long-term goals, but most contractors find that setting up a limited company is the most tax-efficient and financially beneficial way to go about things.
Tax Pros of Being a Sole Trader
As a sole trader, you benefit from having a simpler tax set up with less admin. You don’t need to think twice about all the different aspects of limited company tax, as being a sole trader keeps things simple. You have fewer legal responsibilities, your income is taxed through submitting a self-assessment tax return, and claiming expenses is straightforward. A lot more goes into submitting an accurate tax return if you’re operating through a limited company.
However, there are some downsides. For example, all of your profits are taxed as income and you don’t have the chance to take any dividends. This gives you less opportunity for tax planning, and it makes it more difficult to lower your tax liability. You’re also personally liable for business debts
Tax Pros of Setting Up a Limited Company
As we mentioned above, there are a number of tax benefits that come with setting up a limited company. That’s why it’s a route a lot of contractors take. For example, you could potentially benefit from lower tax on profits, especially if you take some income as dividends. You also benefit from limited liability protection and a more professional image. Of course, like being taxed as a sole trader, there are a few negatives.
Setting up a limited company for your contracting tends to result in more complex accounting and compliance. You also have to manage annual filing and reporting obligations, which can be complex and time-consuming if you’re not experienced.
Managing taxes as a contractor doesn’t need to be overwhelming, not with the help of Go Limited. With the right structure, planning and expert advice, you can stay compliant, reduce your tax liabilities and keep more of what you earn.

FAQs
Managing Taxes as a Contractor Within a Limited Company Structure
What taxes do I need to pay as a limited company contractor?
As a contractor working through a limited company, you’ll be responsible for several types of taxes, including:
- Corporation Tax – paid on your company’s profits (currently 19% or 25% depending on profit levels).
- Income Tax – on any salary you draw from the company.
- Dividend Tax – on profits distributed to you as dividends.
- National Insurance Contributions (NICs) – both employer and employee NICs may apply on salary.
- Value Added Tax (VAT) – if your turnover exceeds the VAT threshold (currently £90,000), or you choose to register voluntarily.
How do I pay myself from a limited company?
Most contractors use a tax-efficient method combining:
- A low salary (to stay within personal allowance and reduce NICs).
- Dividends from company profits, which are taxed at lower rates than income.
This helps maximise your take-home pay while staying compliant with HMRC.
What is the most tax-efficient way to withdraw money from my company?
The common structure is:
- Pay yourself a salary up to the NIC threshold.
- Draw the rest of your income as dividends, after allowing for Corporation Tax.
- Consider making employer pension contributions directly from your company – these are usually Corporation Tax deductible.
Do I need to register for VAT?
Yes, if your annual turnover exceeds £90,000, VAT registration is mandatory. However, many contractors voluntarily register to:
- Reclaim VAT on business expenses.
- Use schemes like the Flat Rate Scheme to simplify accounting.
Do I need to complete a Self Assessment tax return?
Yes – even if you operate through a limited company, you still need to:
- File an annual Self Assessment to declare your salary, dividends, and any additional income.
- Submit it by 31 January each year to avoid penalties.
What expenses can I claim through my limited company?
Allowable business expenses may include:
- Office equipment and software.
- Travel costs for business journeys.
- Professional insurance (e.g. PI insurance).
- Training courses, if they relate to your current work.
- Accountancy fees and business-related subscriptions.
These can help reduce your taxable profit and overall Corporation Tax bill.
How does IR35 affect my limited company taxes?
If a contract falls inside IR35, your income is treated more like employment income, and:
- You may need to pay PAYE tax and NICs on all income from that engagement.
- Your tax efficiency is reduced compared to outside IR35 contracts.

Important:
Please note: Any rates and thresholds mentioned in this article are correct at the time of publishing and may be subject to change.
When choosing an accountant, look for one with proven experience and expertise in the contracting sector, particularly around areas like IR35, limited company tax matters and off-payroll working. Formal qualifications are important, but relevant hands-on knowledge matters just as much — especially in a complex and fast-changing landscape like this.
