|---|---|---|
| Gross Income (before expenses) | — | £29,004 |
| Personal Allowance | First £12,570 tax-free | −£12,570 |

If your Self Assessment tax bill is over £1,000, HMRC expects you to make Payments on Account toward the next year's tax bill:
This means a self-employed facilities supervisor will need to budget for 18 months of tax in their first year, then roughly 1.5× their annual tax bill in subsequent years.
These are the specific expenses HMRC allows a self-employed facilities supervisor to claim. Only genuine "wholly and exclusively" business expenses qualify.
Multi-tool, Inspection camera, Tool bag, Safety boots, Hard hat, High-vis clothing
Cost of tools and specialised equipment used solely for work can be claimed as a capital allowance if you're self-employed. For employees, only claimable if required by the job and not provided by the employer, and only for the cost of replacing or repairing them.
ClaimableSteel-toe boots, Hard hat, High-vis vest, Safety goggles, Gloves
Protective clothing that is necessary for the job and used only for work is fully claimable. Ordinary clothing is not allowable, even if worn at work.
ClaimableMileage for site visits, Parking fees, Tolls, Van lease payments (business use)
If you use your own vehicle for work, you can claim mileage at HMRC-approved rates (45p per mile for first 10,000 miles, 25p thereafter). Commuting to a regular workplace is not claimable. If you have a van, you can claim expenses proportionally to business use.
Partially claimableWork-related calls, Data for remote access to systems, Work apps
Only the business proportion of costs can be claimed. If you have a separate contract for business, it's fully claimable. Otherwise, you must apportion bills based on actual usage.
