Understanding where the role of a facilities assistant sits in the UK pay spectrum is the first step to managing tax effectively.
Your effective tax rate is the percentage of your gross income that goes to Income Tax and National Insurance. It's typically lower than the 20% basic rate because the first £12,570 is tax-free.
People in this role typically work under these employment arrangements:
Majority of Facilities Assistants are directly employed (PAYE) by large organisations, facilities management firms, or public sector bodies. A minority work as self-employed contractors, often through agencies or on short-term contracts. A small grey area exists with umbrella company workers and casual labour.
If you're employed as a facilities assistant, your employer handles tax and National Insurance through PAYE. Here's what's actually happening behind the scenes.
Under PAYE, your employer deducts Income Tax and Employee National Insurance from your gross pay before you receive it. Here's a breakdown for the average facilities assistant earning £21,576/year:
| Deduction | Calculation | Amount (annual) | Amount (monthly) |
|---|---|---|---|
| Gross Pay | — | £21,576 | £1,798 |
| Personal Allowance | First £12,570 tax-free | −£12,570 | −£1,048 |
| Income Tax (20%) | £9,006 × 20% | £1,801 | £150 |
| Employee NI (8%) | £9,006 × 8% | £720 | £60 |
