Freelancer to Limited Company: A Complete UK Guide

Moving from sole trader to limited company is one of the most common transitions for UK freelancers and contractors. Done at the right time and in the right way, it can reduce your tax bill significantly, protect your personal assets from business liability, and give clients greater confidence. This guide covers when to incorporate, how to extract money tax-efficiently, and the ongoing compliance obligations you will take on.

1. When to Incorporate

Incorporation is not right for everyone — the benefits must outweigh the additional complexity and costs. Consider incorporating when:

• Net profit consistently exceeds £30,000–£35,000: below this level, the tax savings from a salary-plus-dividend strategy are often smaller than the additional accounting and admin costs of running a limited company
• IR35 risk is low: if most of your work is likely inside IR35, a limited company provides minimal tax advantage; you should carefully assess your status before incorporating
• You want limited liability protection: as a sole trader, you are personally liable for all business debts; a limited company is a separate legal entity, so your personal assets (home, savings) are protected if the business fails (subject to no personal guarantees being given)
• Professional image matters: some clients — especially larger corporates and public sector bodies — prefer to contract with limited companies
• You want to retain profits: a limited company lets you leave profits in the company (paying only 19–25% corporation tax) and draw them out in future years at a more favourable time, rather than paying income tax on all profits each year as a sole trader

3. Registering at Companies House

Registering a limited company is straightforward:

• Online registration: via the Companies House web incorporation service or a formation agent. Cost: £12 for the standard online service.
• Same-day registration: applications submitted before 3pm on a working day are typically processed the same day. The 'same-day' premium service costs £78.
• What you need: company name (must not be the same as or too similar to an existing registered name), registered office address in England/Wales/Scotland/Northern Ireland, at least one director (you), at least one shareholder (you), share structure (typically 1 ordinary share at £1), articles of association (model articles are fine for most freelancers)
• Persons of Significant Control (PSC): you must register anyone with significant control — owning more than 25% of shares or voting rights, or having the right to appoint or remove a majority of directors. Most single-director companies register one PSC (the director/shareholder).
• You will need to open a business bank accountin the company's name before trading.

4. Director Salary Strategy

As a director-shareholder, you can choose how much salary to take. The two main strategies for 2024/25 are:

• Salary at the personal allowance: £12,570/year (£1,047.50/month)
  • No income tax on the salary
  • No employee NI (below the primary threshold of £12,570)
  • Employer NI applies above the secondary threshold of £9,100, but the Employment Allowance (£5,000 from April 2024) can offset this — however, Employment Allowance is not available to companies where the sole employee is also a director
  • Best strategy if you have at least one other employee to qualify for Employment Allowance
• Salary at the secondary NI threshold: £9,100/year (£758.33/month) or the lower earnings limit
  • No income tax (below personal allowance)
  • No employee NI
  • No employer NI (at or below the secondary threshold)
  • Best strategy for a single-director company with no other employees and no access to Employment Allowance
  • Leaves some personal allowance unused, but avoids any NI entirely

The salary is deductible as a business expense, reducing the company's corporation tax liability. The balance of profits above your salary can be extracted as dividends.

5. Dividend Extraction

Dividends are payments made to shareholders from post-corporation-tax profits. They are more tax-efficient than salary because they are not subject to National Insurance. For 2024/25:

• Dividend allowance: £500 (reduced from £1,000 in 2023/24). Dividends within this allowance are tax-free.
• Basic rate (income up to £50,270): 8.75%
• Higher rate (income £50,271–£125,140): 33.75%
• Additional rate (income above £125,140): 39.35%

Dividends must be paid from retained profits — you cannot pay dividends if the company has no distributable reserves. Before declaring a dividend, check the company's balance sheet confirms sufficient retained profit. Issue a dividend voucher for each payment and record it in the board minutes. Dividends cannot be paid monthly as salary — they are irregular distributions from profit, not remuneration.

6. Corporation Tax

Your limited company pays corporation tax on its taxable profits after deducting allowable business expenses and your director salary:

• Small profits rate: 19% — applies to profits up to £50,000
• Marginal relief — applies to profits between £50,000 and £250,000; the effective rate tapers from 19% to 25%
• Main rate: 25% — applies to profits over £250,000

Corporation tax is due 9 months and 1 day after the accounting period end for companies below the large company threshold. You must file a Company Tax Return (CT600) with HMRC within 12 months of the accounting period end. Allowable business expenses include equipment, software subscriptions, professional memberships, accountancy fees, and a proportion of home office costs.

7. VAT Registration

VAT registration is compulsory once your taxable turnover exceeds £90,000 in any rolling 12-month period (from April 2024):

• Voluntary registration: you can register below the threshold, which allows you to reclaim input VAT on business purchases. This is beneficial if you have significant VAT-able business costs and your clients are themselves VAT-registered (and can therefore reclaim the VAT you charge them).
• Standard VAT accounting: charge VAT at 20% on your invoices, reclaim VAT paid on purchases, and pay the difference to HMRC via quarterly MTD (Making Tax Digital) submissions using compatible software.
• VAT Flat Rate Scheme (FRS): available for businesses with turnover below £150,000. You pay a fixed sector percentage of your gross turnover (e.g. 14.5% for IT consultants) rather than tracking individual input/output VAT. Simpler to operate, but 'limited cost trader' rules (spending less than 2% of turnover on goods) mean many service businesses now pay 16.5% under FRS, making the scheme less advantageous.
• Cash accounting VAT: pay VAT only when you receive payment (not when you invoice), which helps cash flow for businesses with slow-paying clients.

8. Business Bank Account

A limited company is a separate legal entity, so it must have its own bank account. Mixing personal and company finances is a common mistake that complicates accounting and can undermine limited liability protection.

Options and typical costs:

• Traditional high street banks (Lloyds, Barclays, HSBC, NatWest): monthly fees typically £8–£15/month, with transaction charges. Often require an in-branch meeting and can take 2–4 weeks to open.
• Digital challenger banks (Starling, Monzo Business, Tide, Revolut Business): lower or no monthly fees, faster onboarding (often fully digital within 24–48 hours), good mobile apps, and accounting integrations.
• You will need the account before you can run payroll, receive client payments in the company name, or pay dividends from the company.

9. Accounting and Record Keeping

Running a limited company involves more accounting obligations than being a sole trader:

• Bookkeeping: record all income and expenditure, keep receipts, reconcile bank statements monthly. Cloud software (Xero, QuickBooks, FreeAgent, Sage) makes this significantly easier and is required for MTD VAT filing.
• Accountant costs: a good accountant for a straightforward one-person limited company typically costs £600–£2,000/year including annual accounts, corporation tax return, self-assessment, and payroll. Shop around — online accountants (Crunch, Gorilla Accounting, Coconut) often offer competitive fixed monthly packages.
• Annual accounts: must be filed with Companies House within 9 months of the accounting period end. Micro-entity or small company accounts may be abbreviated.
• Confirmation statement: filed annually with Companies House (£13 fee online), confirming the company's registered details are correct.
• Self-assessment: as a director/shareholder, you must also file a personal self-assessment tax return by 31 January each year covering your salary, dividends, and any other personal income.

10. IR35 and Off-Payroll Working

IR35 is one of the most complex issues for freelancers operating through limited companies:

• Chapter 8 IR35: applies to engagements with small private sector clients (fewer than 50 employees, turnover below £10.2M, balance sheet below £5.1M) and historically all public sector work before April 2017. In these cases, your own company must determine your status and, if inside IR35, apply a 'deemed salary' calculation and pay tax and NI accordingly.
• Chapter 10 (off-payroll working): introduced for public sector in 2017 and extended to medium and large private sector clients from April 2021. The client (or agency) must issue a Status Determination Statement (SDS) deciding whether the engagement is inside or outside IR35. If inside, the fee payer (agency or client) deducts income tax and NI before paying your company.
• CEST tool: HMRC's Check Employment Status for Tax online tool provides an indication of status. HMRC will stand behind a CEST result if the information given is accurate. However, CEST does not cover all scenarios (notably mutuality of obligation) and its results are sometimes disputed.
• Key factors for status: substitution right (can you send someone else to do the work?), control (does the client direct how, when, and where you work?), mutuality of obligation (are you obliged to accept work and is the client obliged to offer it?), financial risk, and integration into the client's business.
• If caught by IR35, most of the income received by your company will be treated as a deemed salary, significantly reducing the tax advantage of the limited company structure.
