The most important information we need for your CIS tax return claim is:

  • Your pay and tax information - The monthly statements from your contractors should tell you what you've earned and the tax they've taken out. Officially, those are called "CIS statements", but they might be calling them wage slips or vouchers where you work.
  • Details of the sites you’ve worked on.

It's not a huge deal if you can’t remember the when and where of every site you’ve worked on. Just give us as much information as you can. Many of our customers work on the same sites so even if you don't have all the location details we probably do. We can also contact ex-employers for you if necessary.
