Working as a self-employed locum pharmacist offers flexibility and the opportunity to manage your own schedule. However, it also brings specific financial responsibilities, particularly regarding tax obligations. Understanding these requirements is essential to avoid unexpected liabilities and to ensure compliance with tax authorities. In this article, I will guide you through the key aspects of locum tax obligations, practical tips for managing your finances, and how to optimise your tax position effectively.
Navigating Locum Tax Obligations
When you work as a self-employed locum pharmacist, you are responsible for managing your own tax affairs. This means you must register as self-employed with HM Revenue & Customs (HMRC) and submit an annual Self Assessment tax return. Unlike employed pharmacists, taxes are not automatically deducted from your income, so you need to keep accurate records and plan for tax payments.
Key Tax Responsibilities Include:
Registering as self-employed: You must notify HMRC within three months of starting your locum work.
Maintaining detailed records: Keep track of all income and allowable expenses related to your locum work.
Submitting a Self Assessment tax return: This is usually due by 31 January following the end of the tax year.
Paying Income Tax and National Insurance Contributions (NICs): These payments are based on your taxable profits.
It is important to understand which expenses you can claim to reduce your taxable income. Common allowable expenses for locum pharmacists include travel costs between assignments, professional subscriptions, indemnity insurance, and equipment or uniforms necessary for your work.

Practical Tips for Managing Tax Obligations
Use accounting software: This helps keep your records organised and simplifies the Self Assessment process.
Set aside money regularly: Allocate a percentage of your income for tax payments to avoid year-end surprises.
Keep receipts and invoices: These are essential for verifying your expenses if HMRC requests evidence.
Consider professional advice: An accountant specialising in locum tax matters can help optimise your tax position.
Locum Tax Obligations: What You Need to Know
Understanding the specific tax obligations for locum pharmacists is crucial. Since you operate as a sole trader, your income is subject to Income Tax and Class 2 and Class 4 National Insurance Contributions. The rates and thresholds for these taxes can change annually, so staying informed is vital.
Income Tax
Your taxable income is calculated by deducting allowable business expenses from your total locum earnings. The Income Tax rates for the 2023/24 tax year in the UK are:
Personal Allowance: Up to £12,570 tax-free
Basic rate: 20% on income between £12,571 and £50,270
Higher rate: 40% on income between £50,271 and £125,140
Additional rate: 45% on income above £125,140
National Insurance Contributions
As a self-employed individual, you pay:
Class 2 NICs: A flat weekly rate (£3.45 per week for 2023/24) if your profits exceed £12,570.
Class 4 NICs: A percentage of profits (9% on profits between £12,570 and £50,270, and 2% on profits above £50,270).
VAT Considerations
If your annual turnover exceeds the VAT threshold (£85,000 for 2023/24), you must register for VAT. This involves charging VAT on your invoices and submitting regular VAT returns. Many locum pharmacists operate below this threshold, but it is important to monitor your income.

Which Pharmacist Has the Highest Salary?
When considering locum work, it is useful to understand how salaries compare across different pharmacist roles. Salaries vary depending on experience, location, and sector. Generally, hospital pharmacists and those in specialised clinical roles tend to earn higher salaries than community pharmacists.
Locum pharmacists often command higher hourly rates than their employed counterparts due to the flexibility and short-term nature of their work. However, this higher rate must be balanced against the additional responsibilities of managing tax and business expenses.
Factors Influencing Pharmacist Salaries:
Experience and qualifications: Advanced clinical skills or specialisations can increase earning potential.
Location: Salaries tend to be higher in London and the South East compared to other regions.
Sector: Hospital and industry pharmacists often earn more than those in community settings.
Employment status: Locum pharmacists may earn more per hour but must cover their own taxes and expenses.
Understanding these factors can help you set realistic financial goals and plan your locum career accordingly.
Managing Expenses and Maximising Tax Efficiency
One of the advantages of being self-employed is the ability to claim allowable expenses to reduce your taxable profits. It is essential to distinguish between personal and business expenses and to keep thorough records.
Common Allowable Expenses for Locum Pharmacists:
Travel and subsistence: Costs of travelling between assignments, including mileage or public transport fares.
Professional fees and subscriptions: Memberships to professional bodies such as the Royal Pharmaceutical Society.
Indemnity insurance: Essential for protecting yourself against professional liability.
Equipment and uniforms: Items necessary for your work, such as lab coats or medical devices.
Training and development: Courses and seminars related to your professional development.
Tips for Expense Management:
Keep all receipts and invoices: Digital copies are acceptable and easier to organise.
Separate business and personal finances: Use a dedicated bank account for your locum work.
Review expenses regularly: This helps identify deductible costs and avoid missing claims.
Consult an accountant: They can advise on less obvious expenses and ensure compliance.
By carefully managing expenses, you can reduce your tax liability and improve your overall financial position.
Planning Ahead to Avoid Year-End Tax Surprises
Tax planning is a critical part of managing your locum work. Many self-employed pharmacists face unexpected tax bills because they do not set aside funds throughout the year. Developing a clear plan can help you avoid this stress.
Strategies for Effective Tax Planning:
Estimate your tax liability early: Use previous years’ data or online calculators to forecast your tax bill.
Make payments on account: HMRC requires advance payments towards your next tax bill in January and July.
Keep a tax reserve fund: Regularly set aside a portion of your income in a separate account.
Use financial tools: Apps and software designed for self-employed professionals can automate calculations and reminders.
Benefits of Proactive Tax Management:
Avoid penalties and interest for late payments.
Maintain better cash flow throughout the year.
Reduce stress by knowing your financial position at all times.
By adopting these practices, you can focus on your locum assignments without worrying about unexpected tax demands.
