When employees and directors travel for work, they often incur costs for travel, meals, accommodation and other business‑related expenses. Understanding how UK tax rules treat these costs is essential for both employers and employees to avoid unexpected tax liabilities and ensure compliance.
Travel expenses are costs incurred while carrying out business duties away from the normal workplace. These may include:
Public transport fares
Mileage and vehicle running costs
Taxi or ride‑share fares
Overnight accommodation
Parking and toll charges
For tax purposes, travel expenses must be wholly, exclusively and necessarily incurred in the performance of duties.
Travel costs can be reimbursed tax‑free when they meet certain conditions:
Expenses are usually tax‑free if the employee or director:
Is travelling on business (not commuting)
Is travelling to a temporary workplace
Has a genuine business reason to incur the cost
Common examples include travel to:
Client meetings
Conferences or training away from the usual workplace
Temporary work locations
In these cases, reimbursement should not create a taxable benefit.
Subsistence costs cover meals, accommodation and other essential living expenses when an employee or director is away from home and workplace on business.
Typical examples include:
Overnight stays on business trips
Meals during business travel
Accommodation charges
Subsistence relief is available when such expenses are incurred wholly, exclusively and necessarily for business. The cost must be reasonable and supported by evidence.
Travel between home and the normal workplace (commuting) is not eligible for tax‑free reimbursement. For tax purposes:
Commuting — travel from home to your regular place of work and back
Business travel — travel to perform duties at a location that is not your usual workplace
Drivers often misunderstand this distinction, but HMRC treats commuting relief as a personal expense and not tax‑free.
A workplace may be treated as “temporary” if an employee or director attends it for a limited duration, and it is not expected they will be there indefinitely. The rules can be complex, but generally:
A temporary workplace may qualify the travel as business travel
There must be a time limit or expectation that duties will move on
For example, short‑term projects or site visits may qualify
Careful assessment is needed to ensure the travel qualifies as business travel for tax‑free treatment.
When employees use their own vehicle for business travel, employers may reimburse mileage at approved HMRC rates:
Cars and vans: a set pence per mile (typically higher for the first 10,000 miles, then lower thereafter)
Motorcycles: a separate approved rate
Bicycles: a fixed rate per business mile
Reimbursements at or below the approved mileage rates are tax‑free. Where higher rates are paid, the excess may be treated as a taxable benefit.
Where subsistence payments are made, they must be reasonable and supported by receipts:
Meals — costs for food and drink while away on business
Accommodation — hotel or other overnight stay costs
Incidental costs — small, necessary costs (e.g., laundry on extended trips)
Reimbursement supported by receipts and within reasonable limits can be tax‑free, provided the travel qualifies as business.
Accurate records are essential to support tax‑free travel and subsistence claims:
Receipts, boarding passes and invoices
Journey details (date, purpose, locations)
Mileage logs (where personal vehicles are used)
Business purpose and duration
Good record keeping protects both employer and employee if HMRC enquiries arise.
Directors of companies must meet the same tax tests for travel and subsistence. However, there are additional considerations:
Company car or vehicle arrangements
Reimbursement policies under director contracts
Whether travel is to a “permanent” workplace for directors with multiple roles
Directors should be clear about company travel policies and the tax treatment of reimbursements.
Some frequent mistakes in travel and subsistence claims include:
Reimbursing commuting costs as business travel
Failing to maintain adequate supporting documentation
Paying flat daily allowances unrelated to actual business activities
Using incorrect mileage rates
Professional review and clear policies help avoid these pitfalls.
