What Taxes Do You Pay as a Contractor?


As a contractor, the tax you’ll have to pay varies depending on whether you’re operating as a sole trader or you’re working through a limited company. If you choose to set up a limited company and run your business that way, you’ll need to pay Corporation Tax, Income Tax, National Insurance Contributions (NICs) and Value Added Tax (VAT).


Corporation Tax

 If you’ve previously worked as an employee or self-employed freelancer, paying Corporate Tax will be new to you. This is the tax that you pay on your business’ profits. As of the 2023/2024 tax year, the corporation tax rate is 25% for profits over £250,000. For profits under this threshold, the rate is 19%.


Income Tax

As a director of a limited company, you also need to pay income tax on the salary and dividends you draw from the company. Your salary is taxed like any other employee - at a rate of 20% or 40%, depending on your earnings - while dividends are taxed at a lower rate. This is why a lot of contractors use dividends as a way to boost their income in a tax-efficient way.


National Insurance Contributions (NICs)

As a contractor operating through a limited company, you must pay Class 1 NICs on your salary, but any dividends you receive are not subject to NICs. NICs on your salary can add up, which is why a lot of contractors try to strike a balance between taking a salary and dividends for maximum tax benefit.


VAT (Value Added Tax)

 If your annual turnover exceeds the VAT threshold of £85,000, your business will need to register for VAT. VAT is a consumption tax that’s added at every stage of a product’s production and distribution, and it’s similar to a sales tax. Once you’re registered, you must charge VAT on your services and pay it to HMRC. But, you can also claim VAT back on your purchases related to your business.


Dividend Tax

You’ll have to pay tax on dividends and that happens at a different rate to income tax. The rate is generally rate, making dividends a tax-efficient option for contractors. The first £1,000 in dividends is tax-free, and any dividends beyond that are taxed at rates of 8.75%, 33.75% or 39.35%, depending on your overall income.


How Contractor Taxes Are Calculated


It’s important to know what the tax calculation is for a contractor limited company, as this will help you to keep on top of how much you owe, why you owe it and when it needs to be paid. There’s a lot that goes into the calculation of contractor tax and things such as how you take money from the business, your income and your expenses are all taken into account.


Corporation Tax

Corporation tax is calculated based on your business’ profits, which is calculated based by deducting allowable expenses from how much you’ve made. The figure that’s left, which is your profit, is what corporation tax is based on.


Income Tax and NICs

Once corporation tax has been calculated, income tax and NICs are then factored in. As a contractor, your salary is treated in the same way it would be as an employee, and you pay them based on a percentage of your earnings.


Dividends

If your company distributes profits in the form of dividends, they are subject to dividend tax. Since dividend tax rates are lower than income tax rates, contractors often use this approach as a way to reduce their overall tax liability. It’s one of the main limited company tax benefits, as opposed to using an umbrella company.

Tax Deductible Expenses for Limited Company Contractors


There are a lot of contractor and limited company tax benefits, one of which is that you can claim various tax-deductible expenses to reduce your taxable profit. These expenses are a key part of reducing limited company tax, saving you money in the long run.


Travel and Transport

You can claim for travel costs, as long as they are related to your business. This includes fuel, car insurance and public transport, as long as the travel is work related and you can prove how much you paid.


Home Office Expenses

If you’re a contractor or freelancer who works from home, you can claim a portion of your household expenses, such as electricity, heating and internet bills. You can do this by working out the percentage of the bill that’s related to your business, but HMRC does also offer a simplified expenses approach.


Equipment and Supplies

 If you have to buy equipment and supplies for your business, you can include them as a deductible expense. This includes computers, phones, office furniture and stationery used exclusively for your business.


Professional Services

There’s a range of professional services that you can deduct as an expense, including accountancy fees, legal advice, and any other professional services directly related to your business operations.


Training and Development

You can claim for professional training for limited company contractors, as long as it’s related to your work. This could include courses or seminars to enhance your skills relevant to your contracting work, or attending industry events to network.


Meals and Entertainment

Meals and coffee that are business-related - for example, that were incurred during a client meeting - are deductible. However, you do need to be cautious with personal meals, as they won’t be allowed as tax-deductible expenses. You’ll need to prove that the meal, drink or entertainment was solely for business purposes.


tax efficiency contractors

As you can see, there are a whole host of benefits that come with having a personal services company, so it makes sense that it’s a route a growing number of contractors are taking. Whether you’re in IT and technology, finance and accounting, or engineering and consulting, you’re sure to find that having a personal services company has its benefits.

What Makes a Personal Services Company Different to Being a Sole Trader?

There are some key differences between being a sole trader and contracting through a personal services company, which we have explained below. A PSC is often the best limited company for contractors, but it’s important to understand that it’s not the same as being a sole trader.


Sole Trader vs. Personal Services Company

A sole trader is someone who operates a business alone. While setting up as a sole trader is quick and simple, it doesn’t have as many benefits as a PSC. For example, as a sole trader, your personal assets are at risk if your business faces financial trouble. This isn’t the case with a PSC, which provides limited liability, meaning that your personal assets are generally protected.



Another difference is that a sole trader’s income is taxed through personal income tax, whereas a PSC can pay dividends, which can result in you having a smaller tax bill.

Sole Trader vs Limited Company Tax


As a contractor, you’ll have to decide whether you operate as a sole trader or a limited company, and the tax implications could be what sways you one way or another.


Sole Trader


As a sole trader, your business income is taxed as personal income, meaning that you’ll pay income tax and National Insurance Contributions on all your earnings. You can’t split your income between salary and dividends, which can mean that being a sole trader is less tax-efficient for higher earners.


Limited Company


As a contractor with a limited company, your business is a separate legal entity to you. You pay corporation tax on your profits, and then you pay income tax and National Insurance on your salary. Dividends are taxed at a lower rate than the income tax you’d pay as a sole trader, meaning that the limited company tax structure tends to be more tax-efficient for contractors.


How to Plan for Taxes as a Contractor


A big part of managing contractor taxes is planning; this means planning for ways to minimise your tax liability, but also planning to make sure you’re compliant with all tax regulations.


Use Dividends Efficiently

One way to minimise your tax liability is to take a low salary and maximise dividends, as this will reduce your income tax and NICs.

Keep Track of Expenses - It’s important to stay organised and keep detailed records of all tax-deductible expenses for limited company contractors. If HMRC investigates you, you’ll need to show that the expense was solely for business use.


Pension Contributions

You can reduce your tax liability with pension contributions. Contribute to a pension scheme to reduce your taxable income, whilst helping you to save for retirement.


Hire an Accountant

A limited company contractor accountant can help you to navigate limited company tax. They’ll make sure that you're making the most of available deductions and allowances.


Set Aside Funds for Tax Payments

You don’t want to be blindsided by a tax bill that you can’t pay. Set aside a percentage of your earnings throughout the year so you’re prepared for tax payments when they are due. If you’re late payment, you’re likely to incur interest and penalties.
