Most trades businesses don’t realise this until it’s too late.
CIS and domestic reverse charge VAT isn’t “just admin”, it’s where small mistakes quietly build up until HMRC or your subcontractors come knocking.
Wrong deductions.
Materials included when they shouldn’t be.
Or subcontractors not properly verified at all.
Individually, it doesn’t feel like much.
At year end? It turns into missing rebates, penalties and conversations you really don’t want to be having.
And then there’s the deadline on the 19th each month - miss it and it’s an automatic £100 fine.
This is exactly the kind of admin that quietly drains time, money and focus from actually running your jobs.
If any of this feels familiar, it’s worth getting it checked properly before it becomes a year-end problem, get in touch - https://links.oompf.global/widget/booking/TdokGrCVkT0oPbuoXLyr
