We’re IR35 specialists

IR35 is tax legislation designed to prevent contractors and freelancers from providing services via an intermediary, such as a limited company, but who would normally be classed as an employee if that intermediary did not exist.

As a contractor, you will need to ensure you are compliant with the rules. This is made more difficult as HMRC do not make it easy to distinguish between contractors and employees and there are a variety of questions you need to answer to get an decision.

We’ll provide unbiased help and advice to ensure you are compliant with HMRC and pay the correct amount of tax based upon your individual circumstances.

Find out what your take-home pay could be:

Calculate your take-home pay to see how much you could earn

You can use our simple calculator to provide an illustration of what your take-home pay could be, depending on your rate of pay and working hours.

The calculator is only a guide and should not be relied upon to give an actual figure, but it does help explain the differences between the different structures and how this affects your take home pay.

Check how we calculate these figures

Our take-home pay calculator does make a number of assumptions in the background in order to calculate the figures.

The limited company calculator assumptions:

Tax rates are based upon 2019/2020 and assumes no other personal income and that your company is incorporated and operated within the UK.

An individual’s personal allowance is £12,500 for the year (2019/2020).

All profits after tax are withdrawn from the company as dividends.

Flat rate scheme is applied to the company turnover figure at a rate of 16.5% with a first-year discount of 1% applied.

Expenses are inclusive of VAT.

The income is not subject to IR35 and the contract is outside.

Director’s salary is assumed at £8,632 per year

Limited company accountancy fees are already assumed within the calculation and based upon the Express service package at £120+VAT

Employment allowance is not applied.
