Set Up a Limited Company for Contracting
Going limited is one of the most popular routes for UK contractors, and for good reason. A limited company, often called a personal service company (PSC) in contracting, can be more tax-efficient than working through an umbrella, gives you full control of your finances, and presents you as a professional, established business to clients and agencies. At Form My Company, we help contractors across IT, engineering, consulting, healthcare, and many other fields set up their limited companies quickly and correctly.
This guide walks you through how to set up a limited company for contracting, the key things to understand like IR35, and how we make the process simple.
Why Set Up a Limited Company for Contracting?
Many contractors choose a limited company over an umbrella arrangement because of the benefits it offers:
- Tax efficiency. Operating through your own company can be more tax-efficient, as you can draw income through a combination of salary and dividends, depending on your circumstances.
- Take-home control. You manage your company’s finances directly, rather than having a third party deduct fees and tax before you’re paid.
- Professional credibility. A limited company looks more established to clients and recruitment agencies, and many contracts are offered on the basis of working through one.
- Limited liability. Your personal assets are generally protected if the business runs into difficulty.
- Expenses. You may be able to claim legitimate business expenses through the company, subject to the rules.
It’s worth noting the right structure depends on your situation, including your IR35 status, so professional accounting advice is always recommended.
Understanding IR35 Before You Start
If you’re contracting through a limited company, IR35 is essential to understand. The off-payroll working rules, known as IR35, make sure that a worker who provides services through their own intermediary pays broadly the same Income Tax and National Insurance as an employee would, where they would have been an employee if providing services directly to the client.
In short, a contract is either “outside IR35” (genuinely self-employed, taxed more efficiently through your company) or “inside IR35” (treated like employment for tax). Getting this right matters, as an incorrect determination can lead to backdated tax and penalties.
There’s also an important recent change to be aware of. From 6 April 2026, the financial thresholds that determine whether an end client counts as small for IR35 purposes increased, with turnover rising from £10.2 million to £15 million and the balance sheet total from £5.1 million to £7.5 million, while the employee headcount remains at 50. This matters because responsibility for status differs by client size. Private sector businesses classed as small do not need to consider the off-payroll working rules, and the limited company contractors they engage must consider their own IR35 status under the original Chapter 8 rules. In practice, this means more contractors working for smaller clients are now responsible for assessing their own status, so reviewing your contracts is wise. Because IR35 is complex, we strongly recommend specialist advice from a contractor accountant.
How to Set Up Your Contracting Limited Company in Simple Steps
Setting up your company with Form My Company is quick and fully online:
Step 1: Choose Your Company Name
Pick a unique, professional name for your contracting business. We’ll instantly check its availability with Companies House.
Step 2: Appoint Yourself as Director and Shareholder
Most contractors are the sole director and shareholder of their PSC. We’ll guide you through providing the necessary details.
Step 3: Provide a Registered Office Address
You’ll need a UK registered office address. To keep your home address off the public register, you can use our professional Bolton BL1 address.
Step 4: Complete Identity Verification
Provide your ID and proof of address so the required verification can be completed, in line with current UK rules. We handle this remotely.
Step 5: We File Your Company
We submit your incorporation to Companies House, and you receive your Certificate of Incorporation and company documents, often within hours.
What You’ll Need After Incorporation
Forming the company is the first step. To start contracting properly, you’ll also want to:
- Open a business bank account. Essential for keeping your company finances separate. We can introduce you to suitable banking partners.
- Register for taxes. Your company will need to register for Corporation Tax, and you may need to register for VAT and set up PAYE if you take a salary.
- Appoint an accountant. A contractor accountant is highly valuable for managing your accounts, tax, dividends, and IR35 position.
- Get insured. Many contracts require professional indemnity and public liability insurance.
Limited Company vs Umbrella: A Quick Comparison
Contractors often weigh a limited company against an umbrella company. An umbrella is simpler, with the umbrella acting as your employer and handling tax through PAYE, which can suit those on short-term or inside-IR35 contracts. A limited company involves more administration but offers greater tax efficiency and control, making it popular for those with outside-IR35 work or longer-term contracting plans. Many contractors with a mix of contracts keep their limited company running, as it remains the more flexible long-term option. The best choice depends on your contracts and circumstances, so it’s worth discussing with an accountant.

Frequently Asked Questions
Why do contractors set up a limited company?
A limited company, or personal service company, can be more tax-efficient than an umbrella, gives you control of your finances, and presents you professionally to clients and agencies. The right choice depends on your IR35 status and circumstances.
What is IR35 and why does it matter for contractors?
IR35, or the off-payroll working rules, ensures contractors who work like employees pay broadly similar tax to employees. Your contracts are either inside or outside IR35, which affects how you’re taxed, so getting it right is important.
Did IR35 change in 2026?
Yes. From 6 April 2026, the small company thresholds rose, meaning more contractors working for smaller clients are now responsible for assessing their own IR35 status. It’s worth reviewing your contracts and seeking specialist advice.
Can I be the only director and shareholder of my contracting company?
Yes. Most contractors set up as the sole director and sole shareholder of their personal service company. We guide you through the whole process when you form your company with us.
Is a limited company better than an umbrella for contracting?
It depends on your situation. A limited company offers more tax efficiency and control but involves more admin, while an umbrella is simpler. Contractors with outside-IR35 or longer-term work often prefer a limited company.
Do I need an accountant for my contracting company?
It’s not legally required, but it’s highly recommended. A contractor accountant helps with your accounts, tax, dividends, and especially your IR35 position, which is complex and carries real financial risk if handled incorrectly.
How quickly can I set up my contracting company?
With Form My Company, your company can often be formed within hours of submitting your details and completing identity verification, with your documents delivered digitally so you can get started fast.
