CIS contractors – a quick reminder you don’t want to miss
From April 2026, there’s been an important change.
You now need to submit a CIS return every month even if you haven’t used any subcontractors.
That means each month you must either:
✔️ File a return showing payments
✔️ Submit a nil return
✔️ Or make an inactivity request (which can last up to 6 months)
If nothing is submitted, penalties can build up quickly:
£100 to start
£200 after 2 months
Then £300+ (or 5% of the liability) after 6 months
Further penalties after 12 months
It’s easy to think “nothing to report” means “nothing to do” but HMRC doesn’t see it that way.
If you’re already filing regularly, you’re likely fine. But if you’re unsure, it’s worth checking now before any penalties land.
If you’d like help keeping on top of this (or taking it off your to‑do list completely), just send us a message and we’ll be happy to help.
