What is IR35 for IT contractors?
First introduced in 2000, IR35 is a series of subsequent ax laws (rolled out over a number of years) that were enacted through the annual Financial Acts. The UK government uses IR35 as a way to make sure that IT contractors and others pay the correct income tax and national insurance tax. In essence IR35 is a tool which allows HMRC to treat you for tax purposes as an employee of your end client rather than a sole-trader or the owner of a limited company.
While HMRC can’t class every IT contractor as an employee of their end client. IR35 allows them to look for two main indicators when deciding how a contractor should be treated tax wise.
The first is very clear cut; since 2017 any IT contractor working for a public sector end client has generally been considered inside IR35 (although this isn’t the case 100% of the time).
The second is less clear; do you act as an IT contractor or an employee?
Employees wouldn’t have the freedom to choose how, when or where they worked – the same as employees. They might not be able to turn down work given to them, in the same way that an employee cannot refuse to do work. If you removed the intermediary (their limited company) from the process, they would be an employee in all but name (referred to as a disguised employee).
Working through a limited company, these ‘disguised employees’ would be entitled to lower taxation through dividends and corporation tax, and thus short change HMRC of tax revenue.
On the other hand, legitimate self-employed workers can choose their working style, accept or refuse work, pick their own workplace or outfit and only have to work on a project-to-project basis.
While the number of IT contractors acting as disguised employees was actually very small, by the fact of being a contractor they were swept up in IR35. Over time as IT contractors adapted their working practices and contracts to abide by the rules, IR35 has been repeatedly adapted.
Controversially what started as a set of rules to catch small time low paid workers turning to contracting to save tax turned into a full scale assault on legitimate contractors and their tax affairs (as HMRC realized the tax revenues it could generate as a result of targeting high earning workers like IT contractors).
The rules of IR35 will be changing again in April 2020 to automatically catch all private sector IT contractors.
How did IR35 affect the public sector?
One of the most controversial changes to the rules of IR35 happened in 2017. In April that year, new ‘off-payroll’ rules came into effect. Before these rules it was down to the contractor to prove that they were genuinely self-employed. This is called being ‘outside IR35,’ and means that you are correctly paying the lower taxes reserved for entrepreneurial workers. The alternative is referred to as being ‘inside IR35,’ which is the same as being a disguised employee.
As of 2017 it was no longer a public sector IT contractors responsibility to decide if they were caught by IR35. The public sector end client that you worked for had to prove to HMRC that you were a legitimate contractor with financial penalties if they got it wrong. Naturally under the threat of financial losses most departments simply blanket classed their contractors as inside IR35.
