← All insights

1. Reporting late

Every pay run must be reported to HMRC on or before payday. Late reports lead to penalties, even when the tax itself is paid on time.

2. Ignoring tax code notices

HMRC sends updated codes during the year. Missing one means employees pay too much or too little, and both cause awkward conversations.

3. Forgetting pension auto-enrolment

Every employer has duties to assess staff and enrol those who qualify. The deadlines apply from the first day you employ someone.

4. Treating staff as contractors

If someone works like an employee, they usually are one for tax purposes. Getting this wrong can mean years of back tax.

5. Keeping no records of changes

Starters, leavers and pay changes should be recorded before payday, not reconstructed afterwards. A short checklist each month avoids most problems.
