How to use the Sole Trader vs Limited Company Calculator

1. Enter your annual business profit: This is your total business income minus allowable expenses, before any personal tax or National Insurance. It’s the figure HMRC uses as the starting point for your tax calculation.

Not sure of your exact figure? Use your most recent year’s accounts or a realistic estimate.

2. Select your IR35 status: If you work through a limited company but your engagement resembles employment (common for contractors and some freelancers), IR35 may apply. Selecting “Inside IR35” flags where the limited company tax advantages are largely negated, so you get an honest picture rather than a misleading one.

3. Choose your director’s salary strategy: As a limited company director, your salary is a deductible business expense. You can take £0, £9,100 (eliminating all National Insurance), £12,570 (preserving your full personal allowance), or a custom amount. Each choice produces a different tax outcome. The calculator models all of them.

4. Set your desired annual take-home: This is the key field that makes this calculator different. Rather than assuming you extract every penny, tell the calculator how much you actually want in your pocket this year. Anything beyond that stays inside the company, available for reinvestment, future extraction, or building a business reserve.

5. Add an employer pension contribution (optional): If your limited company makes pension contributions on your behalf, those payments are deducted before corporation tax is calculated. Enter any planned annual contribution to see the impact on your tax bill.

6. Click “Compare Sole Trader vs Limited Company Tax Efficiency” Your full comparison generates instantly showing: total tax paid; personal take-home; retained company profit; effective tax rates; and a set of planning insights specific to your inputs.

The calculator gives you the numbers, but the right structure for your business depends on more than tax alone.

Liability protection, your future growth plans, how you want to pay yourself, and the administrative overhead of running a limited company all factor into the decision.

If you’re unsure which structure is right for you, or you want a specialist to review your current setup and identify planning opportunities you might be missing, our accountants at WallsMan Creative work exclusively with creative professionals… and we understand the financial realities of your industry.
