As a care worker in the UK, you dedicate your time to helping others. But when it comes to managing your taxes and finances, you might find yourself needing some care and support too. Whether you’re self-employed or working through an agency, understanding your tax obligations and expense claims is essential for maximizing your income and staying compliant with HMRC regulations.
This comprehensive guide will walk you through everything you need to know about care worker accounting in the UK, from registering as self-employed to claiming allowable expenses and avoiding common tax return mistakes.
Registering as a Self-Employed Care Worker in the UK
If you provide care services independently rather than as an employee, you’ll need to register as self-employed with HMRC. This is a crucial first step in your care worker accounting journey.
How to Register with HMRC
To begin working legally as a self-employed carer, you must register with HMRC by the 5th of October in your business’s second tax year. For example, if you started working as a self-employed carer in June 2023, you would need to register by October 5, 2024.

The registration process can be completed online through the HMRC website, by phone, or by post using form CWF1. Once registered, you’ll receive your Unique Taxpayer Reference (UTR) number, which you’ll need for all future tax-related matters.
Steps to Register as Self-Employed:
- Visit the HMRC website and select ‘Register for Self Assessment’
- Create a Government Gateway account if you don’t already have one
- Complete the registration form with your personal details
- Provide information about your care work activities
- Submit your application and make note of your UTR number
Important: Your UTR is a 10-digit number unique to you. Keep it safe as you’ll need it when filing your tax returns and for any correspondence with HMRC regarding your self-employed status.
Understanding Tax Obligations for Care Workers
As a self-employed care worker, you’re responsible for calculating and paying your own income tax and National Insurance contributions through the Self Assessment system.
Income Tax
You’ll pay income tax on your profits (income minus allowable expenses) above the Personal Allowance threshold, which is £12,570 for the 2023/24 tax year. Tax rates then apply in bands:
- Basic rate: 20% on profits between £12,571 and £50,270
- Higher rate: 40% on profits between £50,271 and £150,000
- Additional rate: 45% on profits over £150,000
National Insurance
Self-employed care workers typically pay two types of National Insurance:
- Class 2 if your profits are £6,725 or more a year (£3.45 per week for 2023/24)
- Class 4 if your profits are £12,570 or more a year (9% on profits between £12,570 and £50,270, and 2% on profits above that)

Tax Return Deadlines
Self-employed care workers must file their Self Assessment tax returns by specific deadlines:
| Submission Method | Deadline | Payment Due |
| Paper returns | 31 October | 31 January |
| Online returns | 31 January | 31 January |
| Payment on Account (first installment) | N/A | 31 January |
| Payment on Account (second installment) | N/A | 31 July |
Missing tax deadlines can result in penalties starting at £100 for returns up to 3 months late, with additional penalties for longer delays. Setting calendar reminders for these key dates is essential for care worker accounting in the UK.
