What is Outside IR35?
IR35 is a tax regulation in the UK that determines whether a contractor is truly self-employed or functioning more like an employee. This rule is relevant for individuals who offer services through a limited company, often referred to as a personal service company.
If your contract falls outside of IR35, HMRC considers you self-employed for tax purposes. This status allows you greater flexibility to pay yourself a mix of salary and dividends. Plus, you might have the opportunity to claim a wider range of business expenses.

This calculator is particularly beneficial for contractors with contracts that fall outside of IR35. If your contract qualifies under the outside IR35 guidelines, you can pay yourself in a more tax-efficient manner compared to being inside IR35 or working through an umbrella company.

How the Outside IR35 Calculator Works?
Using our IR35 Take Home Pay Calculator is super easy! Just follow these simple steps to get precise results and really make the most of this handy tool.
Step 1. Select the type of calculation you want: by default we suggest a day rate but you can select between "Day Rate" or "Annual Pay".
Step 2. Your day rate: if you selected "Day Rate" as the calculation type then adjust your day rate.
Step 3. Specify days worked per year: if you selected "Day Rate" then the default we suggest is 200 days due to weekends, public holidays and general holiday time off. 220 days is ambitious and 180 days is a fairly conservative estimate to assume you may have a longer break between contracts.
Step 4. Adjust your annual pay: if you selected "Annual Pay" then adjust this for your estimated annual pay.
Step 5. Estimate your business expenses: enter your estimated annual business expenses. We suggest £3,000 as a pretty conservative estimate for accounting fees and other business related expenses you can claim. Increasing your business expenses can reduce the amount of corporation tax you pay.
Step 6. Add your pension contributions: Enter the amount you contribute to your pension fund.
Step 7. Input gross salary through your Limited Company: Input your total salary paid through your limited company before any deductions. The optimum salary would be £12,570 (your personal allowance) and take the remaining funds as dividends. You'll have a small amount of Employer National Insurance to pay.
Once you’ve entered all the necessary information, our contractor take home pay outside IR35 calculator will provide you with a detailed financial breakdown.
1. Annual Gross Pay: This is your total earnings before any tax or expenses are taken out.
2. Net Profit After Tax: After subtracting your salary and expenses from your total income, the calculator shows:
- Corporation tax charged on your company’s net income: £[amount]
- Corporation tax rate used: [rate]%
- Total corporation tax due: £[amount]
3. Net Dividends Received After Tax: After paying corporation tax, the remaining profit can be taken as dividends. Here’s the breakdown:
- Total available dividends to withdraw: £[amount]
- Tax-free dividend allowance used: £[amount]
- Dividends taxed at 8.75% (basic rate): £[amount]
- Dividends taxed at 33.75% (higher rate): £[amount]
- Dividends taxed at 39.35% (additional rate): £[amount]
- Total dividend tax to pay: £[amount]
4. Net Take-Home Pay: The calculator then adds everything up to show:
