Quick Answer
Most tradespeople should start as sole traders and consider incorporating once consistent annual profits exceed £35,000–40,000. Below that threshold, the extra accountancy costs of running a limited company usually outweigh the tax savings. Above it, the difference in National Insurance and dividend tax versus income tax can save thousands of pounds each year.
Overview: The Two Options
When you work for yourself in a trade — whether you are a plumber, electrician, builder, joiner, or any other tradesperson — you must choose a legal structure for your business. The two most common options in the UK are operating as a sole trader (self-employed) or setting up a private limited company (often called a Ltd company). Both are entirely legitimate, but they carry different tax bills, admin burdens, and legal protections.
Sole trader status is the default for most self-employed tradespeople. You register with HMRC, file a Self Assessment tax return each year, and pay income tax and National Insurance on your profits. There is no separation between you and the business — which is both a simplicity benefit and a risk.
A limited company is a separate legal entity. You are a director and shareholder. The company pays corporation tax on its profits, and you extract money as a combination of salary and dividends. This creates tax planning opportunities, but also significantly more paperwork and higher accountancy fees.
Sole Trader: Tax Breakdown 2026/27
As a sole trader, your profits are treated as personal income and taxed through Self Assessment. The rates below apply for the 2026/27 tax year.
| Tax / NIC | Band / Rate | Notes |
|---|---|---|
| Income tax — personal allowance | 0% on first £12,570 | No tax |
| Income tax — basic rate | 20% on £12,571–50,270 | Max £7,540 in this band |
| Income tax — higher rate | 40% on profits above £50,270 | Stings above this level |
| Class 2 NIC | £3.45/week if profits > £6,725 | ~£179/year; protects State Pension |
| Class 4 NIC | 9% on profits £12,570–50,270 | Adds significantly to tax bill |
| Class 4 NIC — upper rate | 2% on profits above £50,270 | Reduced rate above upper limit |
On £40,000 profit, a sole trader pays roughly: £5,486 income tax + £2,473 Class 4 NIC + £179 Class 2 NIC = approximately £8,138 total (before allowable expenses reduce the taxable profit).
The advantages of sole trader status are real: one Self Assessment return per year, straightforward accounting, no Companies House obligations, and accountancy costs of just £200–600/year. The main disadvantage is unlimited personal liability — if a client sues you or your business accumulates debts, your personal assets (including your home) can be at risk.
Limited Company: Tax Breakdown 2026/27
A private limited company pays corporation tax on its profits and you, as director, extract income as a combination of salary and dividends. The typical strategy is:
- Pay yourself a salary up to £12,570 (the personal allowance) — this is tax-free for you and a deductible expense for the company, but keep it below the NIC secondary threshold to avoid employer NICs.
- Take the rest of your income as dividends from company profits after corporation tax.
| Tax | Rate | Notes |
|---|---|---|
| Corporation tax (profits up to £50,000) | 19% | Small profits rate |
| Corporation tax (£50,001–£250,000) | 19%–25% (marginal relief) | Tapered between thresholds |
| Corporation tax (above £250,000) | 25% | Main rate |
| Dividend allowance | £500 tax-free | Reduced from prior years |
| Dividend tax — basic rate | 8.75% | Much lower than income tax |
| Dividend tax — higher rate | 33.75% | Still below 40% income tax + NIC |
On £40,000 company profit, the company pays corporation tax on profits after paying you a £12,570 salary, then you receive the remainder as dividends and pay 8.75% dividend tax on the amount above your £500 allowance. Total tax burden: roughly £6,800–7,200, compared with ~£8,138 as a sole trader — a saving of around £1,000–1,300. At £60,000 profit the saving widens considerably.
The disadvantages are the additional admin: annual accounts filed at Companies House, a corporation tax return with HMRC, a personal Self Assessment as a director, and full director's legal responsibilities. Accountancy costs rise to £800–2,500/year depending on complexity.
Head-to-Head Comparison
| Factor | Sole Trader | Limited Company |
|---|---|---|
| Setup | Register with HMRC online (free) | Incorporate at Companies House (£50) |
| Tax on profits | Income tax 20–45% + NIC | Corporation tax 19–25% + dividend tax |
| NIC savings | Class 4 NIC at 9%/2% | No NIC on dividends — significant saving |
| Personal liability | Unlimited — home at risk | Limited — personal assets normally protected |
| Admin / filing | One Self Assessment per year | Corp tax, Companies House, Self Assessment |
| Accountancy cost | £200–600/year | £800–2,500/year |
| Professional image | No company name on invoices needed | “Ltd” can enhance credibility with larger clients |
| Pension contributions | Relief via Self Assessment | Company pension contributions reduce corp tax |

When Should a Tradesperson Go Limited?
There is no single magic number, but the most commonly cited threshold is £35,000–40,000 in consistent annual taxable profits. Below that level, the extra accountancy fees and admin time typically cancel out any tax advantage.
Consider incorporation if one or more of the following apply:
- Your annual profits have been consistently above £35,000 for at least one full tax year.
- You want to protect your personal assets — especially if you own property — from business liability.
- You are looking to retain money inside the business for future investment (leaving profits in the company at 19% corp tax is more efficient than drawing them and paying income tax).
- Larger commercial clients or main contractors prefer or require you to be a limited company for contract purposes.
- You want to involve a spouse or partner as a co-director or shareholder for income-splitting purposes (always take proper tax advice before doing this).
Conversely, if you are starting out, your income is variable, or your profits are below the threshold, remaining a sole trader keeps your life simpler and your costs lower. You can always incorporate later — it is a straightforward process and you can transfer your existing sole trader business into a new limited company.
VAT for Tradespeople: Key Points
VAT registration is a separate question from your business structure — both sole traders and limited companies must register once their taxable turnover exceeds £90,000 in any rolling 12-month period (2026/27 threshold). You can also register voluntarily below that level.
Standard VAT vs Flat Rate Scheme (FRS)
Under standard VAT, you charge 20% on your invoices, reclaim VAT on your business purchases (materials, tools, van), and pay the difference to HMRC. This is almost always best if you buy significant materials.
Under the Flat Rate Scheme, you charge 20% to clients but pay HMRC a fixed percentage of your gross (VAT-inclusive) turnover. The FRS rate for general construction services is 14.5%. You keep the difference, but you cannot reclaim input VAT on purchases. This works well for labour-heavy tradespeople who buy few materials.
| Scenario | Better Option |
|---|---|
| Mostly labour, few materials (e.g. electrician supplying small parts) | FRS likely better |
| High material spend (e.g. builder buying timber, plumber buying boilers) | Standard VAT likely better |
| Turnover just over £90,000 threshold | Calculate both — difference can be small |
Note: the Domestic Reverse Charge (DRC) applies to construction services supplied to VAT-registered businesses in the CIS — under DRC the customer accounts for the VAT rather than the supplier. This affects your cash flow but not your overall VAT liability.
IR35 and Tradespeople
IR35 is a set of tax rules aimed at “disguised employment” — situations where an individual works through a limited company (Personal Service Company) but effectively operates as an employee of one client, enjoying contractor rates without PAYE tax and NIC.
The good news for most tradespeople: IR35 is unlikely to affect you. You are likely outside IR35 if you:
- Work for multiple clients throughout the year
- Supply your own tools and equipment
- Set your own working hours on site
- Have the right of substitution (can send someone else to do the work)
- Bear financial risk if the job goes wrong
The risk is higher if you work almost exclusively through your Ltd company for a single main contractor for months at a time, particularly on large public-sector projects. In that case, seek specific advice from an IR35-specialist accountant before incorporating.
Common Pitfalls to Avoid
- Going limited too early. The accountancy cost alone (£800–2,500/year) can exceed any tax saving if your profits are under £30,000. Do the maths first.
- Mixing personal and business money. As a sole trader this is a common habit but makes it harder to claim legitimate business expenses. As a limited company director it is strictly prohibited — company money is not your money.
- Missing the VAT registration deadline. You must notify HMRC within 30 days of the end of the month in which you exceeded the £90,000 threshold. Late registration attracts penalties.
- Forgetting to pay on account. HMRC requires sole traders to make two payments on account each year (31 January and 31 July) once their tax bill exceeds £1,000. Many new sole traders are caught out by a larger-than-expected first bill that includes the first payment on account.
- Ignoring CIS deductions. If you work as a subcontractor under the Construction Industry Scheme, the 20% (or 30%) CIS deductions withheld by your contractor are not a tax — they are advance payments of your income tax and NIC. Keep records so you can reclaim any overpayment. See our CIS tax guide for full details.
- Not keeping mileage records. Business mileage is one of the most commonly missed deductions for sole-trader tradespeople. Keep a log from day one.
Frequently Asked Questions
Should a tradesperson be a sole trader or limited company?
Most tradespeople starting out are best off as sole traders because the administration is simple, accountancy costs are low (£200–600/year), and there is no Companies House paperwork. Once your consistent annual profits exceed around £35,000–40,000, the tax savings from operating as a limited company typically outweigh the additional accountancy fees of £800–2,500/year. The main non-tax factor is liability: a limited company protects your personal assets if the business is sued, whereas as a sole trader your home and savings are at risk.
At what income is it worth going limited as a tradesperson?
The general rule of thumb is that a limited company starts to make financial sense once your taxable profits are consistently above £35,000–40,000 per year. Below that level, the extra accountancy costs (often £800–2,500/year versus £200–600 for a sole trader return) can wipe out any NIC or tax savings. Above £50,000 in profits, the advantage becomes more pronounced because you avoid the 40% higher rate of income tax on dividends while only paying 8.75% basic-rate dividend tax inside a company structure.
What are the tax savings of a limited company for a tradesperson?
The core saving comes from paying yourself a small salary (up to £12,570, within the personal allowance and NIC-free) and extracting remaining profits as dividends, which are taxed at 8.75% (basic rate) rather than 20–40% income tax plus Class 4 National Insurance at 9%. Corporation tax on profits up to £50,000 is 19%, compared with income tax plus NIC that can add up to roughly 29–49% for a sole trader. For a tradesperson making £60,000 profit, the annual saving can be £3,000–8,000 depending on personal circumstances, but always get advice from a qualified accountant.
What is IR35 and does it affect tradespeople?
IR35 (off-payroll working rules) targets individuals who work through a Personal Service Company (PSC) but function essentially as employees of one dominant client — meaning they have no real business independence. Most tradespeople work across multiple clients, supply their own tools, set their own hours, and can send a substitute, which means they fall well outside IR35 and have nothing to worry about. The risk arises mainly when a tradesperson works exclusively through their limited company for a single large contractor or public-sector body for an extended period. If this describes your situation, seek advice from an accountant familiar with the construction sector.
Do I need an accountant as a self-employed tradesperson?
As a sole trader you are not legally required to use an accountant — you can complete your Self Assessment tax return yourself via HMRC's online portal. However, most tradespeople find that a good accountant more than pays for their fee (typically £200–600/year for a sole trader return) through legitimate expense claims and tax planning they would have missed. As a limited company director you almost certainly need an accountant: you must file a corporation tax return, annual accounts with Companies House, and a personal Self Assessment, and the penalties for errors or late filing are significant.
How does VAT work for tradespeople?
You must register for VAT once your taxable turnover exceeds £90,000 in any rolling 12-month period (2026/27 threshold). Once registered, you charge VAT on your invoices (usually 20% standard rate for most trade work) and reclaim VAT on business purchases. Many tradespeople benefit from the Flat Rate Scheme (FRS), where you pay a fixed percentage of your gross (VAT-inclusive) turnover to HMRC — the FRS rate for construction is 14.5%. Whether FRS or standard VAT is better depends on how much VAT you spend on materials; if you buy significant materials, standard VAT typically wins.
