What Is a Temporary Workplace? The HMRC Definition Explained
When managing employee expenses and payroll, understanding HMRC's definition of a temporary workplace is essential — particularly when determining whether travel and subsistence costs are tax-deductible. Get it wrong, and you risk costly compliance errors.
The Official HMRC Definition
According to HMRC's Employment Income Manual EIM32080, a temporary workplace is defined as a place that an employee attends for a limited duration or for a temporary purpose. In plain terms, it is any work location that is not the employee's permanent or regular place of work.
This contrasts with a permanent workplace, which is a location the employee attends regularly as part of their normal working pattern. Travel to a permanent workplace is not eligible for tax relief — but travel to a temporary workplace generally is.
What Makes a Workplace 'Temporary'?
HMRC sets out two key conditions that define a temporary workplace:
- Limited duration: The employee attends the location for no more than 24 months, or it is expected to last no longer than 24 months.
- Specific task: The employee is sent to a location to carry out a particular task or project, after which they return to their usual base.
It is worth noting that if it becomes apparent that attendance at a location will exceed 24 months, it can lose its temporary status — affecting the tax treatment of associated expenses.
Why This Matters for Payroll Managers
Correctly identifying temporary workplaces is critical for processing employee travel and subsistence expenses accurately. Misclassification can lead to underpaid tax, HMRC investigations, and penalties — a significant risk for any SME.
For the full guidance, we strongly recommend reviewing HMRC EIM32080 directly on GOV.UK.
How Temporary Workplace Rules Affect Travel Expense Tax Relief
Understanding the tax treatment of travel expenses hinges on one critical distinction: whether a workplace is permanent or temporary. For payroll managers and admins, getting this right directly affects how you process expense reimbursements and what you report to HMRC.
Travel to a Temporary Workplace Is Generally Tax-Free
According to HMRC's Employment Income Manual (EIM32080), travel and subsistence costs incurred when an employee attends a temporary workplace are generally exempt from both Income Tax and National Insurance Contributions (NICs). This is because the travel is not considered ordinary commuting — it goes beyond the employee's usual place of work.
A temporary workplace is broadly defined as somewhere an employee attends for a limited duration or a specific purpose, rather than as a regular base. If attendance is expected to last no more than 24 months and does not become the employee's permanent workplace, relief typically applies.
Why This Matters for Payroll Processing
For payroll teams, this distinction is more than a technicality — it has a real impact on:
- Expense reimbursements: Correctly identifying temporary workplaces means qualifying travel and subsistence expenses can be reimbursed without triggering a tax or NIC liability.
- P11D reporting: Misclassifying a temporary workplace as permanent — or vice versa — could result in incorrect reporting and potential penalties.
- Employee trust: Employees expect to be reimbursed fairly and without unexpected tax deductions on legitimate business travel.

The 24-Month Rule: A Critical Threshold for Payroll Teams #
One of the most important concepts payroll managers and admins need to understand when handling travel expense claims is HMRC’s 24-month rule. Get this wrong, and what looks like a legitimate tax-free expense reimbursement could trigger an unexpected liability.
What the 24-Month Rule Actually Means #
According to HMRC’s Employment Income Manual (EIM32080), a location can only qualify as a temporary workplace — and therefore allow tax relief on associated travel expenses — if the employee is not expected to work there for a continuous period exceeding 24 months. Crucially, it’s not just about the length of time; it’s also about the proportion of time spent there. If an employee spends, or is expected to spend, more than 40% of their working time at a single location for a period that will exceed 24 months, that location is no longer considered a temporary workplace for tax purposes.
Why the 40% Threshold Matters #
The 40% rule prevents employers from treating what is effectively a permanent or near-permanent place of work as a temporary one simply by rotating employees on paper. HMRC looks at the reality of the working arrangement, not just the contractual wording.
When Does the Clock Start? #
The 24-month period begins from the point at which it becomes apparent — or reasonably expected — that the employee will exceed that threshold. This means payroll teams need to monitor assignments proactively, not reactively. A change in circumstances that makes a long-term stay foreseeable can trigger the rule even before 24 months have elapsed.
For full HMRC guidance on this rule, refer directly to EIM32080 on GOV.UK.
Managing these rules manually across a workforce is time-consuming and error-prone. Essential-expenses.com can help your business save money, reduce admin time, and minimise compliance risk — all in one place.
Common Mistakes Payroll Managers Make with Temporary Workplace Claims #
Getting temporary workplace expenses right is essential for staying compliant with HMRC rules — but even experienced payroll managers can fall into familiar traps. Here are the most common errors to watch out for.
Misclassifying a Permanent Workplace as Temporary #
One of the most frequent mistakes is treating a workplace as temporary when it actually meets the definition of a permanent one. If an employee attends a location regularly and there is no realistic expectation that attendance will end, HMRC will likely consider it a permanent workplace. Incorrectly applying tax relief on travel and expenses to these situations can lead to underpaid tax, penalties, and unwanted HMRC scrutiny.
Failing to Monitor the 24-Month Threshold #
Under HMRC guidelines (see EIM32080), a workplace ceases to qualify as temporary once an employee has attended — or is expected to attend — for more than 24 months. Many payroll teams simply set up a temporary workplace arrangement and forget to review it. Without active monitoring, employees may continue receiving tax-free expense reimbursements well past the point at which eligibility ends.
Not Updating Payroll Records When Circumstances Change #
Employee working patterns change — secondments are extended, contracts are revised, and roles evolve. Failing to update payroll records to reflect these changes is a significant compliance risk. If a temporary arrangement becomes permanent, payroll must be adjusted promptly to ensure the correct tax treatment is applied.
Inconsistent Record-Keeping #
Poor documentation makes it difficult to demonstrate compliance during an HMRC audit. Every temporary workplace claim should be supported by clear records showing the nature of the assignment, expected duration, and actual attendance.
Avoiding these mistakes requires consistent oversight and reliable processes — exactly where the right tools make all the difference.
What HMRC EIM32080 Says: A Direct Reference for Compliance
If you're responsible for processing expenses through payroll, understanding HMRC's official guidance is essential. HMRC Employment Income Manual EIM32080 sets out the rules governing travel expenses to a temporary workplace — and getting this right has a direct impact on your tax obligations and your employees' pay.
The Core Rule: What Qualifies as a Temporary Workplace?
According to EIM32080, a workplace is considered temporary if an employee attends it for a limited duration or for a temporary purpose. Travel expenses to a temporary workplace are generally exempt from income tax and National Insurance contributions, making it a valuable relief for both employers and employees.
The 24-Month Rule
A key threshold in the guidance is the 24-month rule. If an employee is expected to work at the same location for more than 24 months — or if it becomes their base for more than 40% of their working time — that location may no longer qualify as a temporary workplace. Once a site is reclassified as a permanent workplace, associated travel expenses become taxable.
Why This Matters for Payroll
For payroll managers and admins, correctly identifying temporary workplaces ensures that expense claims are processed with the right tax treatment. Misclassification can lead to incorrect PAYE deductions, potential HMRC penalties, and unnecessary tax liabilities for employees.

Frequently Asked Questions: HMRC Temporary Workplace Rules #
What is a temporary workplace according to HMRC? #
HMRC defines a temporary workplace as a place an employee attends for a limited duration or for a specific task, rather than as their regular or permanent place of work. According to HMRC Employment Income Manual EIM32080, a workplace is temporary if the employee does not expect to work there for more than 24 months, or if they spend 40% or less of their working time there. This definition is critical for determining whether travel and subsistence expenses qualify for tax and NIC relief.
Can employees claim tax relief on travel to a temporary workplace? #
Yes. Travel and subsistence costs incurred by an employee travelling to a temporary workplace are generally exempt from Income Tax and National Insurance Contributions (NICs). This means employers can reimburse these costs without deducting tax or NICs, provided the workplace genuinely meets HMRC’s definition of a temporary workplace under EIM32080.
What is the 24-month rule for temporary workplaces? #
The 24-month rule states that if an employee attends a workplace for more than 24 months, or if it is reasonable to expect they will do so, that location ceases to qualify as a temporary workplace. Additionally, if the employee spends more than 40% of their working time at that location over the relevant period, HMRC will treat it as a permanent workplace. Once a location becomes permanent, travel expenses to it are no longer tax-exempt.
What happens if an employee exceeds the 24-month threshold? #
If an employee is expected to — or does — attend a workplace for more than 24 months, spending more than 40% of their working time there, HMRC treats it as a permanent workplace from the point that expectation is formed. Travel and subsistence costs from that point forward are no longer exempt from tax and NICs. Payroll managers must update records promptly to avoid incorrect expense payments and potential HMRC penalties.
What are common mistakes employers make with temporary workplace expenses? #
Common mistakes include: incorrectly classifying a regular office or client site as a temporary workplace; failing to monitor how long employees have been attending a location; not updating payroll records when circumstances change (such as a contract extension); and continuing to pay tax-exempt travel expenses after the 24-month threshold has been reached. These errors can lead to HMRC investigations, penalty charges, and backdated tax liabilities.
Where can I find the official HMRC guidance on temporary workplaces? #
The authoritative HMRC guidance on temporary workplaces is published in the Employment Income Manual at EIM32080. You can access the full official guidance directly at: https://www.gov.uk/hmrc-internal-manuals/employment-income-manual/eim32080.
