The 2026 dividend tax rise narrowed the limited company advantage by £400-£800 a year at typical drawing levels. It did not flip it.
For most UK owner-managers with profits above £35,000-£40,000, limited company still wins on tax. MTD ITSA (live from 6 April 2026 for sole traders with gross income above £50,000) adds quarterly reporting admin that pushes marginal cases toward incorporating. The real decision factors are profit level, whether a spouse can hold shares, and whether you need limited liability.
Two things changed for 2026/27 that matter to anyone weighing up sole trader versus limited company. The dividend rate rose by 2 percentage points. MTD ITSA went live for sole traders with gross self-employment or property income above £50,000. Both affect the break-even math.

What Changed for 2026/27
The 2pt dividend tax rise
From 6 April 2026, dividend tax rates rose by 2 percentage points. Basic rate is 10.75% (was 8.75%). Higher rate is 35.75% (was 33.75%). The additional rate stayed at 39.35%. The £500 dividend allowance is unchanged. See our full dividend tax rise guide for the numbers.
MTD ITSA went live
From 6 April 2026, sole traders and landlords with gross self-employment or property income above £50,000 must comply with Making Tax Digital for Income Tax Self Assessment. That means MTD-compatible software, digital record-keeping, and quarterly updates to HMRC (in addition to the year-end finalisation). The threshold drops to £30,000 from 6 April 2027.
Limited companies are untouched by MTD ITSA (they file corporation tax, not ITSA). So an incorporated business avoids the quarterly filing burden on its trading income. Our MTD guide for agencies covers the software and filing steps.
Employer NI at 15% (from April 2025)
This one is a year old but still relevant. Employer NI is 15% on salary above £5,000 (was 13.8% above £9,100). The £10,500 Employment Allowance absorbs most of it for qualifying companies. Sole traders do not pay employer NI on their own earnings (they pay Class 4 NI instead), so the 2025 change did not hit them.
The Math, 2026/27
Here is the side-by-side cost of extracting £40,000 of post-tax cash to the owner, for a single owner with no spouse share split, at two profit levels.
| Metric | Sole trader | Ltd (£12,570 salary + dividends) |
|---|---|---|
| Profit before tax | £50,000 | £50,000 |
| Tax + NI | £9,720 (IT £7,486 + Class 4 £2,234) | £8,330 (Corp tax £6,976 + div tax £1,354) |
| Cash to owner | £40,280 | £41,670 |
| Annual accountancy cost | £600 (plus MTD software if above £50k) | £1,800 |
At £50k profit, limited saves £1,390 in tax but costs £1,200 more in accountancy fees. Net advantage: roughly £190. That is why the break-even sits close to £35-40k at this drawing level. Push profit to £80k and the tax saving grows to around £2,400-£2,800 a year, comfortably covering the extra admin.
Four Worked Examples
Example 1: £30,000 profit (sole trader wins)
Sarah is a freelance copywriter with £30,000 annual profit and no spouse involved. Sole trader tax: £3,486 income tax + £1,046 Class 4 NI = £4,532. Takes home £25,468. Accountancy fees: £450. Total cost of doing business: £4,982.
If incorporated: £12,570 salary + £17,430 dividend (to pull £30k). Corp tax on £17,430 profit = £3,312. Dividend tax on £16,930 (after £500 allowance) at 10.75% = £1,820. Total tax: £5,132. Accountancy: £1,500. Total cost: £6,632.
Verdict: sole trader is £1,650 better off at this level. Plus simpler admin.
Example 2: £60,000 profit (ltd edges ahead)
Daniel runs a small creative studio with £60,000 profit, single owner. Sole trader: £11,432 IT + £3,734 Class 4 NI = £15,166. Net £44,834. Accountancy £700 + MTD software £180 = £880.
Ltd: £12,570 salary + £47,430 dividends. Corp tax on £47,430 = £9,012. Dividend tax: £37,200 × 10.75% = £3,999 (after £500 allowance, uses remaining basic band). Total tax £13,011. Net £46,989. Accountancy £1,800.
Verdict: ltd wins by £2,155 in tax minus £920 extra admin = £1,235 net advantage.
Example 3: £100,000 profit (ltd clear winner)
Leila consults at £100,000 profit. Sole trader: £27,432 IT + £5,734 Class 4 NI (6% on £37.7k + 2% on £49.7k) = £33,166. She also trips into the £100k personal allowance taper zone. Effective marginal rate above £100k for a sole trader reaches 62%.
Ltd, no spouse: £12,570 salary + £87,430 dividends. Corp tax (marginal relief £50-250k) = £20,375. Dividend tax: £37,200 at 10.75% + £37,160 at 35.75% = £3,999 + £13,285 = £17,284. Total tax £37,659. Accountancy £2,000.
Ltd also lets her drop £20,000 into an employer pension. That pulls her adjusted net income down to £80k and saves further corp tax. Realistic saved tax: £3,500+ a year once pension is factored in. Sole trader cannot do this (personal pension contributions get relief, but far less tax-efficient than employer contributions).
Verdict: ltd wins by £3,500-£5,000 a year, growing with pension optimisation.
Example 4: £150,000 profit with spouse (ltd dominates)
Mark and Priya run a consultancy with £150,000 profit. Both active in the business. As sole trader (unrealistic at this scale without a partnership, but for illustration): Mark draws £150k, IT + NI = £57,500. Effective rate over 38%.
As ltd with 60/40 share split, both on £12,570 salary, pension contributions of £20k each: Mark draws £75k dividends, Priya £50k. Combined tax across corp, dividend, and pension structure: roughly £40,500. Pension pot growing by £40k a year.
Verdict: ltd wins by £17,000 a year plus £40,000 in pension. Over a decade, transformational.
Summary table: who wins at each profit level
| Profit | Single owner | With spouse (active) |
|---|---|---|
| £30k | Sole trader | Sole trader (still) |
| £50k | Close to break-even | Ltd wins |
| £80k | Ltd | Ltd (bigger margin) |
| £100k+ | Ltd clearly | Ltd dominates |
| £150k+ | Ltd + pension | Ltd + pension + split |

Beyond Tax: The Non-Financial Factors
Limited liability
Real in three scenarios: a supplier dispute you lose, a customer claim that exceeds your professional indemnity cover, and a business failure where trade creditors are chasing unpaid invoices. In those situations, the company's debts stay in the company. Personal assets (house, savings) are safe.
Less real than marketing suggests: banks ask directors for personal guarantees on loans and often on premises leases. Wrongful trading rules can make directors personally liable for company debts if they knew (or should have known) the company was insolvent and kept trading. HMRC can also issue personal liability notices for unpaid PAYE in some cases.
Client credibility
For some industries (tech, agencies, consulting), procurement teams prefer limited companies over sole traders. Certain enterprise contracts require a limited company structure. If you sell into large corporates or government, the weight of the answer tilts heavily toward limited.
Admin burden
Limited companies file accounts at Companies House, a confirmation statement annually, a corporation tax return, payroll (monthly or quarterly depending on scheme), and dividend vouchers. Sole traders file Self Assessment. From April 2026, sole traders above £50k also file quarterly MTD ITSA updates plus a year-end finalisation. The admin gap has narrowed. Expect 2-4 extra hours a month for limited company compliance if you do it well (or the equivalent in accountancy fees if you do not).
Pension access
Limited companies can make employer pension contributions that are fully corp-tax deductible and avoid both income tax and NI. This is the single most tax-efficient extraction route in 2026/27. Sole traders can make personal pension contributions and get income tax relief, but the efficiency is far lower. At £80k+ profits, the pension sacrifice benefit alone usually justifies incorporation. See our pension contributions for directors guide.
When to Incorporate (and When Not To)
Incorporate when:
- Annual profit is above £50k and expected to grow
- A spouse or civil partner can genuinely hold shares and participate in the business
- You want to make serious pension contributions (£20k+ a year)
- You sell into clients who prefer or require limited companies
- You need the liability ring-fence (large contracts, product liability, employee risk)
- You are planning to sell the business within 5-10 years (BADR at 18% for 2026/27 applies to share disposals)
Stay a sole trader when:
- Annual profit is consistently below £30k
- Your work is genuinely solo and you do not anticipate material growth
- You are launching and want to validate the market before taking on company admin
- You have a complex international setup where a UK limited company adds residence or permanent-establishment complications
- You would not use the pension sacrifice or spousal share levers anyway
How to Incorporate Mid-Year
The standard sequence:
- Form the company. Set up a new limited company at Companies House. Issue shares to yourself (and spouse, if relevant) at a token value. Costs around £50
- Value and transfer the trade. Agree a commercial valuation for the goodwill and any assets (customer lists, contracts, equipment). Transfer using the incorporation relief rules (s162 TCGA 1992) if the transfer is for shares, to defer any CGT
- Run the sole trader to cessation date. Close the sole trader at a clean month end. File the final Self Assessment for the cessation period
- Register for corporation tax, PAYE, and VAT (if applicable). Set up software (Xero, QuickBooks), payroll, and HMRC filings
- Do the dividend and pension plan. Set your salary at the right level (see the optimal salary and dividend strategy) and plan the first year's extraction
Most transitions happen at the end of the tax year (5 April) or a clean quarter end. Do not skip step 2: the goodwill valuation affects capital gains treatment and directors' loan accounts. If rushed, you can end up with a surprise CGT bill or a directors' loan you cannot legally repay.
Frequently Asked Questions
Is it still worth going limited in 2026/27?
For most people with profits above £40,000, yes. The 2026 dividend tax rise (basic rate to 10.75%, higher rate to 35.75%) narrowed the limited company advantage by £400-£800 a year at typical drawing levels, but limited still wins on tax for most owner-managers once profits pass the mid-£30ks. Below that, sole trader is simpler and usually cheaper once you factor in accountancy fees. The answer depends on your profit level, whether your spouse can hold shares, and whether you need limited liability.
What's the new break-even point in 2026/27?
Around £35,000-£40,000 of annual profit is where limited company pulls ahead on pure tax for a single owner with no spouse involved. Below this, the admin cost of running a limited company (accountancy fees, Companies House filings, dividend vouchers) usually cancels the saving. Above £60,000 the limited company is typically £1,500-£3,000 a year better off. Spousal share rebalancing and pension contributions push the limited company advantage further at higher profit levels.
Does MTD ITSA affect my decision?
Yes. Making Tax Digital for Income Tax Self Assessment went live on 6 April 2026 for sole traders and landlords with gross income above £50,000. Sole traders in scope now need MTD-compatible software and must file quarterly updates plus a year-end finalisation. The extra admin burden tilts marginal cases towards incorporating, since limited companies are already on a single annual CT return and dividend taxation inside the company is unaffected by MTD ITSA.
How much did the 2026 dividend tax rise narrow the gap?
For a director pulling £80,000 mixed salary and dividends, the 2pt dividend rate rise adds around £600-£800 a year to their tax bill compared to 2025/26. Sole trader tax is unchanged (income tax and Class 4 NI rates held). So the limited company advantage shrank by roughly that amount, but it did not flip. Limited still wins on total tax at £80k profit, just by a smaller margin.
What about Class 4 NI for sole traders in 2026/27?
Class 4 NI remains 6% on profits between £12,570 and £50,270, and 2% above £50,270 for 2026/27. Class 2 NI was abolished in April 2024 (self-employed now get state pension credits automatically if profits are above the small profits threshold). So a sole trader's effective marginal tax rate is 26% basic (20% IT + 6% NI) and 42% higher (40% + 2%), vs a director-shareholder at around 30% effective on the basic-rate dividend portion and 42-55% on higher-rate portions.
Can a sole trader claim Employment Allowance?
No. Employment Allowance is an employer NI relief that applies to employer NI liability, which sole traders do not have on their own earnings. If you employ someone through your sole trader business, you claim EA against the employer NI you pay on their salary, not yours. Moving to a limited company and putting yourself on payroll is the standard route to benefit from the Employment Allowance structure.
Is limited liability a real advantage or marketing hype?
Real, but narrower than people think. A limited company's debts are ring-fenced from personal assets in most cases, but banks routinely ask directors for personal guarantees on loans and leases. Directors can also be personally liable for unpaid PAYE, VAT, and corporation tax if they continue trading while knowingly insolvent (wrongful trading). Where the limited liability genuinely helps: supplier disputes, customer claims, and professional indemnity where you also carry insurance.
How much more expensive is a limited company to run?
For a typical owner-managed business, expect £1,200-£2,500 a year in accountancy fees for accounts, corporation tax, payroll, and Self Assessment. A sole trader typically pays £400-£800 for bookkeeping and Self Assessment. The difference (£800-£1,700) is your limited company overhead. That is the amount you need to save in tax to break even on the decision.
Can I switch from sole trader to limited company mid-year?
Yes. You incorporate a new company, transfer the trade and assets to it (often using the incorporation relief rules to defer any CGT on goodwill), and run the sole trader period to the date of transfer. You file a final Self Assessment for the sole trader period and start the corporation tax clock for the limited company. Most transitions happen at a clean month end or tax year end to keep accounts tidy. Talk to an accountant before you do this: the goodwill and incorporation relief side has traps if rushed.
What about the £1,000 trading allowance?
The £1,000 trading allowance is a tax-free threshold for casual self-employment or freelance income, useful for side hustles earning under £1,000 a year (no Self Assessment needed). It is not relevant to serious agencies or consultancies drawing meaningful profit. If your profit is above £1,000, you file normally and the allowance does not apply to your main trade.
Do I need to register for VAT either way?
VAT registration is triggered by turnover, not legal structure. Both sole traders and limited companies must register once VAT-able turnover exceeds the £90,000 threshold in any rolling 12-month period. Some agencies voluntarily register below the threshold to reclaim input VAT on purchases. The Flat Rate Scheme remains available for both structures and is often worth considering for service-based businesses with low input VAT.
What's the simplest rule of thumb for 2026/27?
Profit under £30,000 with simple affairs: stay sole trader. Profit £30,000-£50,000: limited company if you want the liability protection and do not mind the admin, otherwise sole trader. Profit over £50,000: limited company almost always, especially if a spouse can hold shares or you want pension sacrifice. Profit over £100,000: limited company plus spousal share split plus pension sacrifice is materially better than sole trader.
The Bottom Line
The 2026 dividend rise and MTD ITSA did not flip the sole-trader-vs-ltd question. They just moved the numbers. For profits above £40,000, limited company still wins on tax for most owner-managers. The admin and accountancy cost gap narrowed, but so did the tax gap, so the net saving is similar to 2025/26.
The real signals are profit level, whether a spouse can be part of the business, and whether you want the structural benefits (liability, pension sacrifice, credibility). If you are above £50k profit and have not looked at incorporation in the last two years, it is worth running the numbers.
