# PenaltyProof Reviews
**Vendor:** PenaltyProof  
**Category:** [Accounting Practice Management Software](https://www.g2.com/categories/accounting-practice-management)
## About PenaltyProof
PenaltyProof monitors Companies House and HMRC filing deadlines for UK accountants and bookkeepers. Accountants register their client companies and the service checks public data every morning, emailing alerts before deadlines are missed — confirmation statements, annual accounts, PSC, VAT, Self Assessment, MTD ITSA, payroll and ECCTA obligations. Alerts escalate as deadlines approach. Free tier available; paid plans from £29/month.
