Sole Trader vs Limited Company: which saves you more in 2025/26?

For most freelancers and contractors with profits below about £80,000, the tax difference between sole trader and limited company in 2025/26 is small. The 2024 reduction in Class 4 NIC from 9% to 6% and the previous rises in dividend tax rates have narrowed the gap considerably. Above £80,000 of profit limited company structure starts to pull ahead, especially when pension contributions, family share planning or retained earnings are taken into account. Use the calculator above for your specific numbers.

From 6 April 2026, dividend tax rates rise by 2 percentage points on the ordinary rate (from 8.75% to 10.75%) and the upper rate (from 33.75% to 35.75%). The additional rate stays at 39.35%. Toggle the calculator above to the 2026/27 tax year to see the impact. For a director taking £40,000 of dividends in the basic rate band, the rise costs around £760 per year. For a director taking £80,000 in the higher band, the rise costs around £1,600 per year.

The calculator gives a pure tax comparison based on annual profit. It does not model: pension contributions paid by the company (which are deductible against profit and shift more of the comparison toward limited company), spouse or family share planning to use multiple Personal Allowances, retained earnings strategy, Director's loan accounts, share class structuring, or any State Pension qualifying year considerations. For all of these we recommend a Tax Planning Workshop where the chartered team models your full position. Fee is £1,200 fixed and typically pays for itself many times over within 12 months.

By default, sole director without Employment Allowance: £5,000 (Secondary Threshold) so no Employer NIC at all. With Employment Allowance available (multi-employee businesses): £12,570 (full Personal Allowance, all Employer NIC covered by the £10,500 Employment Allowance). You can switch between these in the calculator. Most freelance or contractor limited companies are single director without Employment Allowance, so £5,000 is the default.

The calculator deducts £505 per year from the limited company take-home figure. This represents the typical fee uplift between sole trader Self Assessment (around £695 per year for a Tier 2 sole trader package) and limited company Tier 1 accounts (£1,200 per year). It is the realistic ongoing accountancy cost difference of choosing limited company structure. If your Tax Planning Workshop reveals £4,000 to £8,000 of pension or family planning savings on top of the pure tax comparison, the £505 uplift is recovered many times over.

Yes. UK limited company formation is £400 one-off and includes Companies House filing, share structure setup, registers, and VAT and PAYE registration where needed. Existing sole traders incorporating mid-trade need careful handling of trade transfer, Capital Gains Tax incorporation relief and Stamp Duty Land Tax considerations on any business assets.
