If your business provided benefits in kind during the 2025/26 tax year, they need to be reported to HMRC on a P11D.
The deadline is 6 July. The Class 1A National Insurance on those benefits is then payable by 22 July.
Miss it and the penalties start, and they grow the longer it is left. The good news is that with the right records it is a straightforward job, and we still have time to do it properly before the deadline.
If you are not sure whether you even need to file one, that is exactly the question to ask now rather than in July.
