If you are a self-employed counsellor, psychotherapist, or mental health practitioner in the UK, managing your tax responsibilities doesn’t have to be overwhelming. With the right knowledge, you can stay compliant, reduce your tax bill, and focus on your clients.
This guide covers the essentials you need to know about UK tax for self-employed therapists including key deadlines, allowances, and what is changing with Making Tax Digital (MTD).
1. Do You Need to Register as Self-Employed?
Yes — if your gross income from clients exceeds £1,000 in a tax year (6 April to 5 April), you must register with HMRC as self-employed.
Even if you are also employed, any private practice income over this threshold requires registration. You must register by 5 October following the end of the tax year.
- The £1,000 Trading Income Allowance: Should You Use It?
The trading income allowance lets you earn up to £1,000 tax-free from self-employment without declaring it.
But here’s the catch:
You cannot claim both the trading allowance and actual business expenses.
Use the £1,000 allowance if:
– Your allowable expenses are under £1,000 (e.g., low-cost home office, minimal training).
– You want simpler record-keeping.
Claim actual expenses if:
– Your costs (supervision, insurance, CPD, room rental, software) exceed £1,000.
– You want to maximise tax relief.
3. Key Tax Thresholds for 2025/2026
You only pay income tax on earnings above £12,570.
You only pay Class 2 National Insurance if your profits exceed £6,845.
4. What Expenses Can Therapists Claim?
You can claim allowable business expenses to reduce your taxable profit. Common deductions include:
- Professional indemnity insurance
- Supervision fees
- CPD courses and membership fees (e.g., BACP, UKCP)
- Home office costs (proportion of rent, utilities, broadband)
- Therapy room rental
- Books, software, and apps (e.g., note-taking, scheduling)
- Travel (mileage at 55p per mile for first 10,000 miles)
- Marketing and website costs
Keep receipts and records — HMRC may request them.
