A contractor loan scheme is a tax avoidance arrangement where non-UK employers have paid you untaxed income or given you a loan instead of part of your salary.
If you’ve taken part in a contractor loan scheme you may still have to pay Income Tax on the loan.
You can use the contractor loans settlement opportunity to bring your tax affairs up to date on the best possible terms. This opportunity is for the tax years up to 5 April 2011 and is now open until 30 June 2015.
