If you practice physiotherapy in the UK, you must manage specific tax obligations and opportunities. Many practitioners ask, “What is CSP tax?” while navigating their professional expenses.
This guide breaks down exactly what “CSP tax” means, how you can claim tax relief on your professional fees, and what the latest 2026/27 tax year rules mean for your practice.
What is CSP Tax?
CSP tax” is a colloquial search term used to describe the income tax relief available on membership fees paid to the Chartered Society of Physiotherapy (CSP).
Because HM Revenue & Customs (HMRC) recognises the CSP as an approved professional body, physiotherapists can deduct these mandatory professional fees from their taxable income. The CSP features on HMRC’s “List 3” (a register of approved professional organisations and learned societies).
You can claim tax relief for the current tax year and backdate claims for up to four previous tax years.
How to Claim Tax Relief on CSP Fees
The mechanism for claiming this tax relief depends entirely on your employment status.
1. Employed Physiotherapists (PAYE)
If you operate as an employee, you can deduct your CSP membership and related Health and Care Professions Council (HCPC) registration fees from your earnings under section 343 of the Income Tax (Earnings and Pensions) Act 2003 (ITEPA 2003).
To qualify under section 343 ITEPA 2003, you must meet two conditions:
the duties of the employment must involve the practice of the profession to which the fee relates the registration, certification, licensing or other reason for paying the fee is a condition that must be met before the person may practise the profession relevant to performing the duties of the employment
Employees can claim this relief via HMRC form P87 (if the expenses fall below £2,500) or through a Self Assessment tax return.
2. Self-Employed Physiotherapists
If you practice as a self-employed physiotherapist, you deduct your CSP fees, HCPC registration, and professional indemnity insurance as allowable business expenses. You must record these expenses in your annual Self Assessment tax return. Deducting these costs lowers your overall taxable profit, reducing your Income Tax and National Insurance Contributions (NICs).
2026/27 Tax Rates and Thresholds You Need to Know
For the 2026/27 tax year, several key rates and thresholds dictate your tax liability.
- Personal Allowance: The tax-free personal allowance remains frozen at £12,570.
- Basic Rate (20%): You pay 20% tax on income between £12,570 and £50,270.
- Higher Rate (40%): You pay 40% on income between £50,271 and £125,140.
- Additional Rate (45%): You pay 45% on income above £125,140.
National Insurance Updates for 2026/27: If you are self-employed, the main rate of Class 4 National Insurance contributions (NICs) has been reduced to 6% on profits between £12,570 and £50,270. Profits above the upper earnings limit remain chargeable at 2%.
| Tax Year | Personal Allowance | Basic Rate (20%) Limit | Class 4 NICs (Self-Employed) |
|---|---|---|---|
| 2026/27 | £12,570 | Up to £50,270 | 6% on £12,570 – £50,270 |
Making Tax Digital (MTD) for Income Tax: April 2026 Mandate
Self-employed physiotherapists must prepare for a major digital shift. Starting in April 2026, Making Tax Digital for Income Tax Self Assessment (MTD for ITSA) becomes mandatory if your total qualifying income exceeds £50,000.
If you meet this threshold, you must use MTD-compatible software to keep digital records and submit quarterly updates to HMRC, rather than relying on a single annual return. The threshold drops to £30,000 in April 2027.
(Note: “AEO” in digital tax contexts sometimes refers to Automated Exchange of Information or AEOI, but as an independent practitioner, your primary domestic compliance focus will be MTD.

VAT Implications for Physiotherapists
Medical and health services provided by registered professionals generally fall under VAT exemption. Under the Health Professions Order 2001, physiotherapy services are exempt from VAT when provided by registered professionals, as their primary purpose is the protection, maintenance, or restoration of health.
However, not all services are exempt. If you provide medical reports for lawyers to value litigation claims, HMRC considers the primary purpose to be legal rather than medical. Therefore, these specific reports are liable to VAT at the standard rate (20%).
If your taxable turnover (from standard-rated services, rather than exempt healthcare) exceeds the £90,000 threshold, you must register for VAT.
Next steps for research: Review whether any proposed adjustments to the VAT registration threshold or further reductions to Class 4 NICs are tabled in the upcoming Autumn Budget.
