A Comprehensive Tax Return Guide for Personal Training Businesses
Home / Post Detail
Running a personal training business can be both rewarding and financially profitable. However, to keep your business healthy, it’s crucial to stay on top of your tax responsibilities. Understanding what HMRC requires, knowing which expenses you can claim, and filing your return on time will not only save you stress but also money.
This guide will walk you through everything you need to know about managing your taxes as a personal trainer — from registration to allowable expenses — so you can focus more on helping your clients and less on paperwork.
Understanding Your Tax Status
Do You Need to Register?
If your personal training business earns more than £1,000 per tax year, you must register as self-employed with HMRC. Even if you’re working part-time alongside another job, you’ll still need to declare your personal training income.
Failing to register on time can result in fines and interest charges.
Record-Keeping Essentials
Accurate record-keeping is the backbone of a stress-free tax return. You should keep:
- Invoices and receipts for all income and expenses
- Bank statements
- Mileage or travel logs
- Copies of insurance policies
- Any relevant contracts or agreements
Good record-keeping ensures you don’t miss out on allowable deductions and makes the filing process smoother.
Tax Year and Deadlines
- Tax year: 6th April to 5th April
- Deadline for online returns: 31st January following the end of the tax year
- Payment deadlines:
- 31st January → Final balance & first payment on account (if applicable)
- 31st July → Second payment on account
Missing these dates means automatic penalties from HMRC.
Reporting Your Income
As a personal trainer, your main income usually comes from client sessions. But don’t forget to include other income sources such as:
- Selling fitness products or supplements
- Online coaching or fitness programs
- Affiliate income (if you recommend fitness gear or apps)
- Group classes or workshops
All income streams must be declared to HMRC.
Allowable Expenses for Personal Trainers
One of the best ways to reduce your tax bill is to claim legitimate business expenses. Here are common deductions:
- Equipment & Kit – weights, mats, resistance bands, uniforms, laptops, fitness apps
- Training & Certification – CPD courses, workshops, specialist qualifications
- Business Insurance – public liability, professional indemnity insurance
- Marketing & Promotion – website costs, advertising, business cards, social media ads
- Travel & Mileage – travel to client sessions, gyms, or fitness events (not commuting)
- Workspace Costs – if you work from home, you can claim a portion of utilities, internet, and rent
💡 Tip: Keep receipts for everything. Without proof, HMRC may reject your expense claim.
Completing Your Tax Return: Step by Step
- Gather your documents – income, expenses, receipts, and bank statements
- Log in to HMRC Online – via your Government Gateway account
- Enter income details – declare all earnings from training, sales, or online coaching
- Claim allowable expenses – reduce your taxable income by listing legitimate costs
- Check & review – carefully review for accuracy before submission
- Submit to HMRC – before the 31st January deadline
How Tax Is Calculated
After submission, HMRC calculates your tax based on:
- Income Tax (based on thresholds)
- National Insurance contributions (Class 2 & Class 4 for self-employed)
- Minus allowable expenses
You’ll then receive a tax bill showing the total due.
Should You Hire an Accountant?
While many personal trainers file their own tax returns, working with an accountant can save you time and potentially reduce your tax bill. An experienced accountant can:
- Spot extra deductions you may miss
- Ensure your return is accurate
- Help you avoid penalties
