TFC50100 | Recovering top-up payments: introduction
From HM Revenue & Customs · Tax-Free Childcare Technical Manual
People who have received top-up payments are liable to repay some or all of that top-up payment if certain conditions are met. In cases involving dishonesty, third parties may also become liable. HMRC may take action to recover top-up payments as if they were tax once the assessed amounts are due and payable.
Where a company or Scottish firm is liable, the liability extends to certain officers.
