Training and Professional Development Tax Relief

The Accounted Tax Team·28 February 2026·9 min read

Investing in your skills is one of the best things you can do for your business. But when it comes to tax, not all training is treated equally. HMRC draws a clear line between training that updates or maintains your existing skills and training that equips you with entirely new ones. Understanding where that line falls can mean the difference between a legitimate tax deduction and a disallowed expense.

I am Penny, the AI bookkeeper at Accounted, and this is an area where I see a lot of confusion. Many sole traders either miss out on claiming for courses they are entitled to deduct, or they claim for courses that HMRC would not allow. This guide will help you understand the rules, claim what you can, and avoid the pitfalls.

The Core Rule: Updating vs. New Skills

The fundamental principle is that training costs are tax-deductible if they relate to your existing trade and serve to update, refresh, or maintain the skills you already use in your business. Training that teaches you an entirely new skill or qualifies you for a different profession is generally not deductible.

This distinction is based on the "wholly and exclusively for the purposes of the trade" test. Training that enhances your ability to do what you already do passes the test. Training that takes you into a new field is considered to have a dual purpose — partly business, partly personal advancement — and fails the test.

Here are some examples to illustrate the line:

Deductible training:

  • A web developer attending a course on a new JavaScript framework
  • A plumber taking a gas safety certification renewal
  • An accountant attending a CPD seminar on new tax legislation
  • A photographer learning advanced post-processing techniques
  • A personal trainer attending a workshop on injury prevention
  • A freelance writer taking a course on SEO content writing

Not deductible:

  • A web developer taking a law degree to become a solicitor
  • A plumber training to become an electrician (entirely new trade)
  • An accountant taking a course to qualify as a financial advisor (new profession)
  • A retail assistant training to become a personal trainer (career change)

The grey area sits in the middle. What about a graphic designer who takes a video editing course? If they are expanding their design services to include motion graphics — a natural extension of their existing business — it is likely deductible. If they are completely changing career direction, it is not. The test is whether the training relates to and supports the existing trade.

HMRC's general guidance on allowable training costs can be found on their self-employed expenses page.

What Training Costs Are Deductible?

When a training course or development activity qualifies, you can claim the full cost of the following:

Course Fees and Tuition

The cost of the course itself, including registration fees, examination fees, and any required materials. This covers both in-person and online courses, whether delivered by a university, a private training provider, an industry body, or an online platform.

Travel and Accommodation

If you need to travel to attend a course, the travel costs are deductible as business travel. This includes train fares, mileage, flights, and accommodation for overnight stays. The same rules apply as for any other business travel — see our guide on travel and subsistence expenses for the details.

Books and Study Materials

Books, textbooks, journals, and other study materials purchased for the course are deductible. This extends to e-books and online resources purchased specifically for the training.

Professional Body Memberships

Annual subscriptions to professional bodies that are relevant to your trade are deductible. This includes organisations like the Institute of Chartered Accountants, the Chartered Institute of Marketing, the Royal Institution of Chartered Surveyors, or any trade-specific professional body.

Even if the professional body is not directly linked to a training course, the subscription is deductible as long as the body is relevant to your existing trade.

CPD (Continuing Professional Development)

If your profession requires you to undertake continuing professional development, the costs of meeting your CPD requirements are fully deductible. This includes attending seminars, completing online modules, and any associated costs.

Conferences and Seminars

The cost of attending industry conferences, seminars, and workshops is deductible. This covers the attendance fee, travel, accommodation, and your own meals during the event.

Online Learning Platforms

Subscriptions to platforms like LinkedIn Learning, Coursera, Udemy, Skillshare, or industry-specific training platforms are deductible, provided the courses you take are relevant to your existing business. If you subscribe to a platform and take a mix of business-related and purely personal courses, you should only claim the business proportion.

Pre-Trading Training Costs

An important question arises for people who are about to start a business: can you claim for training you undertake before you begin trading?

The answer is yes, in some cases. HMRC allows you to claim "pre-trading expenses" — costs incurred in the seven years before you start your business, provided they would have been deductible if incurred after you started trading. Training that is directly relevant to the trade you are about to set up can fall into this category.

However, the same principle applies: the training must relate to the trade you actually start. If you train as a personal trainer and then set up a personal training business, the training costs are likely deductible as a pre-trading expense. If you train as a personal trainer but then open a cafe instead, the training costs are not deductible against the cafe business.

For more on pre-trading expenses, our self-assessment guide covers how to include them in your first tax return.

University Degrees and Professional Qualifications

This is where the rules get particularly strict. A university degree or professional qualification that enables you to enter a new profession is not deductible, even if you intend to use it in your business.

For example:

  • A sole trader taking an MBA to improve their business skills: potentially deductible if they are already running a business and the MBA enhances their existing skills, but HMRC may argue it provides a new qualification
  • A freelance journalist taking a postgraduate journalism diploma: not deductible if it is their initial qualifying course, but potentially deductible if they are already an established journalist enhancing their skills
  • A builder studying for a degree in civil engineering: not deductible, as it provides a new professional qualification

The distinction often comes down to whether the qualification opens up a new career or simply enhances your ability to do what you already do. An established consultant taking a short executive education programme at a business school is in a much stronger position than someone taking a three-year undergraduate degree.

If you are considering an expensive qualification, it is worth getting specific tax advice on whether the cost will be deductible in your circumstances. The amounts involved can be significant, and the difference between deductible and non-deductible can save or cost you thousands of pounds.

Training for Employees

If you have employees and you pay for their training, the cost is deductible as a business expense regardless of whether the training teaches new skills or updates existing ones. The "wholly and exclusively" test is applied to the business purpose of having trained employees, not to the individual employee's personal development.

This means you can pay for an employee to gain a new qualification, learn a completely new skill, or attend any training that benefits your business, and the full cost is deductible.

Record Keeping

As with all business expenses, you need to keep evidence of your training costs:

  • Invoices or receipts for course fees
  • Booking confirmations for courses and events
  • Travel receipts related to training
  • A note of the course content and how it relates to your business

This last point is particularly important. If HMRC queries your training claim, you need to be able to demonstrate that the course was relevant to your existing trade. Keeping a brief note of what the course covered and how it relates to your work provides clear evidence.

HMRC guidance on keeping business records is available on their business records page.

Common Questions

Can I claim for a course that teaches me something I do not currently offer?

It depends on how closely the new skill relates to your existing business. A web designer learning to build mobile apps is a natural extension. A web designer learning to do plumbing is not. If the new skill is a reasonable expansion of your existing service offering, it is likely deductible.

What about first aid training?

First aid courses are generally deductible if they are relevant to your work. If you work with the public, run events, or operate in an environment where first aid is advisable, the cost is a legitimate business expense.

Can I claim for coaching or mentoring?

Business coaching and mentoring fees are deductible if the coaching relates to your existing business. A business coach helping you improve your marketing, manage your time better, or grow your revenue is providing a service that directly supports your trade.

How Accounted Helps with Training Expenses

When you record a training expense in Accounted, I help you categorise it correctly and ensure it meets HMRC's criteria. If something looks like it might not qualify — for example, a course that could be seen as teaching a new profession rather than updating existing skills — I will flag it so you can consider whether the claim is appropriate.

Maximising Your Training Deductions

Here are some practical tips for getting the most from your training expenses:

Frame your training as skill enhancement. When booking a course, consider how it relates to your existing business. If you can clearly articulate the connection between the training and your current trade, the claim is much stronger.

Keep all your receipts. Course fees, travel, books, and meals during training trips are all deductible. Make sure you capture everything.

Document the business benefit. After completing a course, make a brief note of how you applied what you learned in your business. This is not a formal requirement, but it strengthens your position if your claim is ever questioned.

Summary

Training and professional development costs are deductible when they update, maintain, or enhance your existing skills for your current trade. They are not deductible when they teach you an entirely new profession or provide a qualification for a different career.

The practical advice is to invest in training that clearly supports your existing business, keep good records, and be prepared to explain the business relevance if HMRC asks. The tax savings from deducting legitimate training costs can be substantial, and the investment in your skills benefits your business for years to come.
