What Happens If You Do Not Use PAYE?
Failure to operate PAYE can lead to HMRC penalties — and they can accumulate monthly. Even small payments must be reported properly. Ignoring PAYE does not save money — it creates risks.
Or you can avoid it entirely: Full PAYE support for 12 months — £400 + VAT. Total: £480/year (~£40/month)
Less than the cost of one mistake.
