A Timeline of Tax Year Legislation affecting contractors

A contractor’s guide to the April 6th legislation changes

The story of this timeline ends in 1999, the year when Chancellor of the Exchequer Gordon Brown delivered his third budget and announced the introduction of IR35. This piece of legislation has alone had the greatest impact upon contractors. We can see its presence in the budget in 2011 when it was announced it was going nowhere.

In attempting to deal with the issue of ‘disguised employment’, IR35 was intended to stop people setting up their own limited company and working as a contractor rather than an employee, with all of the tax benefits this involves. Read more about IR35, including help and advice.

The timeline

This timeline focuses on the policies like the IR35 bombshell in 1999, namely those that have had a total impact upon the working lives of contractors. Not only do the tax and spending changes announced by the Chancellor each year have a direct and often dramatic impact, but they also paint a picture of the political weather of the time, and in particular how sympathetic (or otherwise) the landscape is for contractors.

What follows is a brief guide to the budgets stretching from 2016 back to 1999, and the measure within each budget which may have impacted most specifically upon the lives of contractors:

In summary

Taken as a whole, the landscape for freelancers and contractors is probably more sympathetic now than it was in 1999, driven mainly by a realisation that more people are opting to embrace contracting and more companies are choosing to utilise talent in this manner rather than via direct employment.
