IR35 – Contractors Must Read

IR35 (off-payroll working rules) is critical for contractors operating through a limited company. If HMRC determines that your working relationship resembles employment, all income from that contract is taxed as salary, eliminating the tax benefits of operating as a limited company.

IR35 applies when: You work in the public sector or for a large/medium private sector client. Since 2021, responsibility for determining IR35 status lies with the end client (not the contractor) in these sectors.

Key IR35 factors: control (who decides how work is done), substitution (can you send someone else?), mutuality of obligation (must they offer work, must you accept?).

Sole traders are not subject to IR35. If IR35 is a concern, being a sole trader or umbrella company employee may be simpler.

Making Tax Digital (MTD)

MTD for Income Tax Self Assessment (MTD ITSA) is being introduced in phases:

Limited companies subject to MTD for VAT if VAT-registered (already in force). Corporation Tax MTD is planned for later years.

How Sole Trader vs Limited Company UK 2026 Guide Works

This calculator applies the latest 2025/26 HMRC tax rates to estimate your tax position. The UK uses a progressive tax system where different portions of your income are taxed at different rates. Only income above the tax-free personal allowance is subject to tax, and each band applies only to the slice of income within that range.

Understanding your tax liability helps you make informed decisions about pension contributions, salary sacrifice, gift aid donations, and other tax-efficient strategies. This tool provides an estimate based on standard tax codes, though your actual position may differ if you have multiple income sources or special circumstances.

Key Information for 2025/26

The personal allowance is £12,570 (frozen until 2028). Basic rate: 20% on income from £12,571 to £50,270. Higher rate: 40% on income from £50,271 to £125,140. Additional rate: 45% on income above £125,140. The personal allowance reduces by £1 for every £2 earned above £100,000, creating an effective 60% rate between £100,000 and £125,140.

Example Calculation

On £42,000 annual income: £12,570 is tax-free, then £29,430 is taxed at 20% = £5,886 income tax. National Insurance adds £2,354 at 8% on earnings above £12,570. Total deductions: £8,240, leaving take-home pay of £33,760 per year or £2,813 per month.

Frequently Asked Questions

When should I switch from sole trader to limited company?
Most accountants recommend switching when your profit consistently exceeds £25,000–£35,000 per year. Above this level, the corporation tax rate (19%) plus dividend tax is typically lower than income tax and NI as a sole trader. Your personal circumstances matter, so always get tailored advice.
How much does it cost to set up a limited company?
Registering a limited company at Companies House costs just £12 online and takes around 24 hours. Ongoing costs include an accountant (£500–£2,500/year), confirmation statements (£34/year), and Companies House filings. A sole trader registers for Self Assessment for free.
Is a sole trader or limited company better for IR35?
If you work through a limited company but your engagement falls inside IR35 in the public sector or a large private company, all income from that contract is treated as salary, removing the tax advantages. Sole traders are not subject to IR35, making life simpler if IR35 risk is high.
What are the main tax differences?
Sole traders pay income tax (20%/40%/45%) plus Class 2 NI (£3.45/week) and Class 4 NI (9% on £12,570–£50,270, 2% above). Limited companies pay Corporation Tax at 19%–25% on profits, and directors extract income via salary and dividends taxed at lower rates (8.75%/33.75%/39.35%). No NI on dividends.
Do I need an accountant for a limited company?
You are legally required to file statutory accounts, a confirmation statement, and a Corporation Tax return annually. While you can do this yourself, most directors use an accountant (£500–£2,500/year) to ensure compliance and to optimise their salary/dividend split for maximum take-home pay.
Can I convert my sole trader business to a limited company?
Yes. You incorporate a new limited company, transfer your business assets, and notify HMRC. You must de-register your sole trader Self Assessment if you cease that business. Your accountant can advise on any capital gains implications of transferring assets to the company.
What is Making Tax Digital and does it affect me?
Making Tax Digital (MTD) for Income Tax applies from April 2026 to sole traders and landlords with income above £50,000. Limited companies are already subject to MTD for VAT. Both structures must keep digital records and submit quarterly updates via compatible software.
