Can I claim expenses for business-related medical checks or tests?

Understanding what “claiming expenses” really means

When people ask, “Can I claim expenses for business-related medical checks or tests?”, they’re usually trying to work out whether the cost of a health assessment can be treated as a legitimate business expense rather than a personal cost. In most tax systems, the difference between an allowable business expense and a non-allowable personal expense comes down to one central idea: was the expense incurred wholly and exclusively (or primarily and necessarily, depending on the local rules) for the purpose of the trade, profession, or employment?

Medical checks and tests sit in a particularly sensitive area because health is, by nature, personal. Even when a test is prompted by work—stress, travel demands, exposure risks, regulated industries, or client requirements—the underlying benefit often still attaches to the individual. That’s why medical costs are frequently treated as private expenditure, even where a link to work exists.

However, “frequently” doesn’t mean “always.” There are scenarios where medical checks can be part of a compliant business expense strategy, and there are also scenarios where the safest answer is “no,” because the claim is likely to be disallowed. The goal of this article is to help you understand the typical principles that tax authorities apply, how common fact patterns are treated, what supporting documentation matters, and how to decide your next step without wandering into risky territory.

The core rule: business purpose versus personal benefit

Most tax rules draw a bright line between expenses incurred to generate business income and expenses that are personal in nature. Medical checks are generally presumed personal because they relate to your wellbeing, which exists regardless of whether you operate a business.

To claim a medical check as a business expense, you typically need to show that the expense exists because of the business and would not have been incurred otherwise. In practice, that’s a hard threshold to meet for many routine tests such as general health screenings, annual physicals, blood panels, cholesterol checks, and similar “peace of mind” assessments. Even if you only booked the appointment because you’re busy at work, the fact remains that the result improves your personal health management, not your business output in a direct and exclusive way.

Tax authorities tend to ask questions like: Would you still have this test if you weren’t in business? Does the test protect the business, or does it simply protect the person who runs it? Is the test required by law or regulation for the business to operate? Is it tied to a specific workplace exposure or hazard? Does it form part of an employer’s occupational health responsibilities? These questions help separate rare, potentially claimable cases from the broad category of personal healthcare.

Different contexts matter: self-employed, limited companies, and employees

How you work affects how medical costs are treated. A sole trader, a partner in a partnership, a director/shareholder of a limited company, and an employee can all face different rules and outcomes. Even when the underlying test is identical, the route for claiming it (and the risk of challenge) can change.

If you are self-employed, expenses are typically deducted from business profits. That makes the “business-only” test especially important. Many tax authorities take the view that a self-employed person’s medical costs are private, because they keep the person fit to work, rather than directly generating revenue. They may argue that “staying healthy” is a personal objective that coincidentally benefits your business, not a business objective that happens to improve your health.

If you operate through a limited company, the company can sometimes pay for certain health-related costs as part of employee welfare, occupational health, or benefits. But that can introduce benefit-in-kind rules (meaning you may have a taxable benefit personally) or require payroll reporting. The company may get a deduction, but you might pay tax on the benefit, so the net position could be neutral or even negative depending on your circumstances.

Employees can have work-related medical assessments arranged and paid for by their employer, especially in regulated or safety-critical roles. Whether the employee personally benefits from a tax exemption depends on the jurisdiction’s rules on employer-provided medical benefits and occupational health. Some systems allow a limited exemption for employer-funded health checks; others treat it as taxable compensation.

When medical checks are most likely to be non-allowable

In many everyday situations, the safest assumption is that medical checks are not claimable as business expenses, even if your work was the trigger for booking them. Common examples include:

General annual health screenings, routine blood tests, or “executive health check” packages purchased primarily for personal wellbeing. Even if you pitch it as “to keep me working,” tax authorities often see it as personal maintenance.

Tests related to long-term health management—such as diabetes monitoring, heart health scans, or hormone panels—where the test informs your personal medical decisions. A business benefit is incidental.

Medical tests taken to satisfy your own reassurance or peace of mind, even if your business activity is stressful. Stress can be work-related, but the response is still personal healthcare.

Fitness assessments, gym medical clearances, and sports-related medical checks, even if you argue they keep your energy levels high for work. These are typically viewed as personal lifestyle expenses.

Vaccinations and prophylactic medications can be tricky; while they can be more closely linked to work travel or occupational risk, many tax systems still treat them as personal medical expenditure unless there is a clear occupational health framework or an employer requirement.

When medical checks or tests may be claimable

While many medical costs are non-allowable, there are situations where a medical check or test can have a stronger claim to business relevance. These scenarios typically involve a specific, identifiable business requirement, legal obligation, or workplace exposure that creates a test obligation beyond general personal health maintenance.

1) Mandatory medicals required by law or regulation

If your line of work legally requires you to pass certain medical assessments to perform the job or operate a business activity, the business purpose becomes clearer. Examples in many countries include safety-critical transport roles, certain construction site roles, commercial diving, aviation-related certification, and some security roles. If the medical is a condition of being allowed to do the work at all, the “business nexus” is much stronger.

Even here, the details matter. A tax authority may still ask whether the medical is linked to the role rather than the person. If the medical is a standard licensing requirement and is renewed periodically to allow trading, it can be more persuasive as a business cost than a general health check that you voluntarily undertook.

2) Occupational health checks tied to workplace hazards

Some industries involve exposure to hazards such as loud noise, hazardous substances, dusts, fumes, or other risks. Occupational health surveillance—like hearing tests, lung function tests, or exposure monitoring—can be required by workplace safety rules. If the check exists because of the workplace risk and is undertaken as part of a compliance obligation, this can be closer to an allowable business expense.

Where you are self-employed, occupational health compliance can still apply, though it may depend on whether you have employees, contractors, or access controlled sites. If a site owner requires proof of occupational health surveillance as a condition of access, that can also support business relevance.

3) Client or contract-driven medical requirements

Sometimes a client contract requires certain medical tests or certifications. For example, working on a remote site, offshore project, or in a high-security environment might require a medical clearance. If the contract makes the medical a condition of being allowed to perform the services, the cost is often more defensible as business-related.

The best cases here are where the requirement is explicit in the contract, the test is specific, and it is not a general “health check” but a defined clearance linked to the work environment. Documentation is crucial: keep the relevant contract clause, the client’s written requirement, and evidence that the test is needed to access the work or complete the engagement.

4) Pre-employment or role-specific medical assessments arranged by an employer

Where an employer arranges a medical assessment for a role and pays for it, the employee’s tax position depends on local exemptions. Some jurisdictions treat certain work-related medical assessments as non-taxable, especially when aimed at determining fitness for work or meeting workplace health and safety duties. Others treat employer-paid medicals as a taxable benefit unless a specific exemption applies.

If you are a contractor operating through a company, this can blur. A company may arrange tests for its workers (including directors) if it has an occupational health policy, but directors should be careful about whether the expense is genuinely part of business compliance or simply a way to pay personal healthcare costs through the business.

Common real-world scenarios and how they are usually treated

It can help to think in scenarios, because “medical checks” covers a wide range of situations.

Scenario A: A consultant pays for an executive health check “to stay productive”

This is usually treated as non-allowable. Productivity is a business goal, but the expense is essentially personal health maintenance. The benefit is to the individual’s wellbeing and future health decisions.

Scenario B: A commercial driver pays for a mandatory medical to keep a licence

This is more likely to be treated as allowable, especially if the medical is required to legally perform the work. The test is connected to the permission to trade in that role.

Scenario C: A construction contractor pays for a hearing test required by a site

This can be arguable as a business expense if it is a genuine site requirement tied to occupational health surveillance. The stronger the documentation and the clearer the link to site access, the better.

Scenario D: A business owner pays for blood tests after feeling unwell due to stress at work

Despite the work-related stress trigger, this is generally personal healthcare. The medical purpose is diagnosis and treatment of the person, not a compliance requirement of the business.

Scenario E: A company pays for periodic health checks for all employees

This may be deductible for the company as staff welfare. Whether it triggers a taxable benefit depends on the jurisdiction’s rules, the nature of the checks, and whether there are exemptions for workplace health programs.

Scenario F: A business owner travels frequently and gets travel vaccinations

This sits in a grey zone. The business argument is stronger than for general check-ups because the vaccination is linked to business travel. Still, many tax authorities treat vaccinations as personal medical expenses unless there is a clear employer obligation or a specific rule allowing them. If your jurisdiction permits it, it may still be reportable as a benefit when paid by a company.

Why “business-related” isn’t enough on its own

People often assume that if an expense has any business connection, it must be claimable. But tax authorities usually require more than a connection. Many personal expenses have some business relevance: a good night’s sleep helps you work; healthy food improves focus; exercise reduces sick days. Yet those costs are almost always personal.

Medical checks often fall into that same category of “dual purpose.” Even if you can show that the check helps your business by reducing downtime, it still benefits you personally. If an expense has both business and personal purposes, many systems disallow it entirely rather than allowing an apportionment, especially where the personal element is substantial or inseparable.

That’s why evidence of a specific business requirement matters. “I did it because I’m busy” is weak. “I did it because I need certification X to legally perform contract Y” is much stronger.

Documentation: what you should keep if you plan to claim

If you believe your medical check or test is claimable, the quality of your documentation can make or break the claim. Tax authorities are far more likely to accept a cost when it is supported by objective records that explain why it was necessary for the business.

Useful documentation may include:

A written legal or regulatory requirement showing that the medical is mandatory for the role, licence, or certification. If there is a specific named standard, keep a copy of the relevant guidance.

A contract clause or client email stating that the medical test is required to access a site or commence work.

Invoices that clearly describe the test in a role-specific way. For example, “occupational health surveillance audiometry” is clearer than “health check package.”

Proof of payment from the business account if the business is paying it directly, and evidence of how it relates to the business activity.

Any certificate of fitness or clearance issued as a result of the test, which shows the business requirement outcome rather than personal medical treatment.

Be cautious about storing sensitive medical information. Often, you can document the business requirement without keeping detailed clinical results. You typically want to keep what is necessary for a tax audit without oversharing private medical data.

Company-paid medical checks: deduction versus taxable benefit

If you operate through a company, there can be two separate questions:

First, can the company claim a deduction for paying the medical cost? Second, does the payment create a taxable benefit for the director or employee receiving the medical check?

In many tax systems, companies can deduct staff costs that are incurred for business purposes, including some welfare costs. But a deduction for the company does not automatically mean it is tax-free for the individual. A company can pay for a benefit and deduct the cost, while the individual is taxed on the value of the benefit as compensation.

Some jurisdictions provide specific exemptions for certain health checks, especially if offered to employees generally or as part of occupational health. Others do not. The practical result is that paying through a company is not always a “win.” It might simply shift the tax charge from business profits to personal income tax or payroll taxes.

For owner-managed companies, this is especially important. Tax authorities often scrutinize medical expenses paid by companies because they are a common area where personal expenditure is run through a business. If the medical check looks like personal healthcare, the risk of reclassification is higher.

What about mental health assessments or stress-related checks?

Mental health and stress-related assessments are increasingly common, especially for people in high-pressure roles. The tax treatment tends to follow the same logic: if the assessment is primarily for personal diagnosis or treatment, it is usually a personal expense.

However, employer-provided occupational health services can sometimes include mental health assessments as part of workplace wellbeing. If an employer arranges an occupational health referral to assess fitness for work or to support workplace adjustments, that can be treated differently from privately booking therapy or psychiatric assessments “because work is stressful.”

If you are self-employed, it is usually difficult to argue that therapy or mental health assessments are wholly business-related, even if the stress arises from business demands. The expense is still aimed at treating the individual rather than meeting an external business compliance requirement.

Are first-aid courses and medical training the same thing as medical checks?

No. A first-aid course, safety training, or certification (even if it is “medical” in content) is typically treated as training rather than personal healthcare. Training costs can be claimable where they maintain or improve skills used in the business and meet the relevant rules for allowable training expenses.

A medical check or test is different because it is about the health status of the individual, not the acquisition of a skill. Confusing these categories can lead to incorrect claims. If what you paid for is training (for example, a course that qualifies you to provide first aid at work), that may have a clearer path to deductibility than paying for a health screening.

Travel, visas, and medical tests: a special case

International travel can create unusual requirements. Some countries require medical tests for visas, work permits, or entry in specific circumstances. If a medical test is a mandatory part of obtaining permission to travel for work, the business link can be stronger than for a general health check.

That said, there is still nuance. If the test is required for you personally to travel, it may still be seen as personal. But if travel is clearly for business and the test is a required administrative hurdle, some tax systems may treat it similarly to visa fees or compliance costs. The outcome can vary widely by jurisdiction and the exact nature of the test.

Here, the most practical approach is to treat it like a compliance fee: document the business purpose of the trip, the requirement for the test, and how it is necessary to carry out the work. If the trip has a mixed personal and business purpose, the risk of disallowance increases.

How to decide if you have a reasonable basis to claim

Before claiming, run your situation through a simple set of checks. The more “yes” answers you have, the stronger your position tends to be.

Is the test legally required to carry out your work (licence, certification, regulatory obligation)?

Is the test required by a client contract or a site access condition?

Is the test clearly occupational health surveillance connected to a workplace hazard?

Would you have taken the test if you were not doing this work?

Is the expense limited to the minimum needed to satisfy the requirement, rather than an expanded “health package”?

Do you have written evidence of the requirement?

If you mostly answered “no,” the claim is likely to be risky. If you mostly answered “yes,” you may have a stronger argument, but you still need to check your jurisdiction’s specific rules and how similar cases are treated in practice.

Practical risk management: how to reduce the chance of problems

If you decide to claim a medical check or test as a business expense, consider these risk-reduction steps:

Keep the claim tightly scoped. Claim only what is required for the business requirement. Avoid bundling optional add-ons that look like personal wellness spending.

Make the description business-focused. Your records should reflect the occupational or compliance nature of the cost, not general wellbeing.

Maintain a paper trail. A short email from a client confirming the medical requirement can be more valuable than pages of medical detail.

Avoid aggressive narratives. Phrases like “keeping me healthy to earn money” can sound logical, but they often describe personal maintenance rather than a business necessity.

Consider professional advice for borderline cases. If the expense is significant, it may be worth getting guidance tailored to your legal structure and local rules.

What to do if you already claimed and you’re not sure it was correct

If you have already claimed medical checks and later worry they may not have been allowable, don’t panic. The best approach depends on your jurisdiction, the size of the amount, and whether you have strong supporting evidence. In many places, you may be able to correct an error through an amended return or adjustment in the next period, particularly if you act promptly.

If the amounts are small and infrequent, the risk may be lower, but the principle remains. If the amounts are large or repeated, or if the expense clearly looks personal, it may be sensible to seek advice on whether a correction is appropriate. The key is to address uncertainty rather than ignore it, especially if you anticipate an audit or review.

Clear takeaways you can apply immediately

In most situations, medical checks and tests are treated as personal expenses and are not claimable simply because they help you stay fit to work.

The strongest cases for claiming are those where the medical is mandatory for the work: regulatory medicals, licence renewals tied to fitness standards, client-mandated clearances, or occupational health surveillance linked to specific hazards.

If you operate through a company, the company may be able to pay for certain health-related checks, but that can create a taxable benefit for you or employees. The deduction and the personal tax treatment are separate issues.

Documentation is not optional. If you can’t show a clear requirement and a direct business link, the claim is vulnerable.

When in doubt, keep the approach conservative: treat general health checks as personal, and only claim medical tests where you can demonstrate they exist because of a business requirement, not because of personal health management.

Conclusion: a cautious answer, with room for legitimate exceptions

So, can you claim expenses for business-related medical checks or tests? Sometimes—but most of the time, not in the way people hope. The default position in many tax systems is that healthcare is personal. Even when work motivates the appointment, the expense often remains private because the benefits are inseparable from personal wellbeing.

Where the medical check is a true cost of doing business—because a law, regulator, client, or safety framework requires it—the argument for deductibility can be much stronger. The practical difference lies in whether the test is a condition of being allowed to do the work, rather than an optional step to keep yourself in good shape.

If you’re considering claiming, focus on the purpose, the requirement, and the documentation. Keep the claim narrow and evidence-based. If the expense looks like personal health maintenance, it’s usually best treated as personal—because that is how tax authorities commonly see it. If it looks like compliance, occupational health, or contract access, you may have a legitimate path to claim, provided your local rules support it and your records make the business need clear.
