UK Employee Expenses Rules

Why Your Pan-European Policy May Not Work in the UK

If you’re an HR or Personnel Manager based at group head office and responsible for the UK workforce, it might seem logical to apply a standardised, pan-European or pan-group expenses policy across all countries. However, when it comes to the UK, this approach often causes significant tax compliance issues.

At Türner & Co., we specialise in helping multinational groups navigate the unique rules that apply in the UK.

Why the UK Is Different

The UK has specific and strict tax rules around what can and cannot be reimbursed tax-free. Unlike some other jurisdictions, the UK does not allow generous round sum (per diem) allowances unless specific criteria are met. If your group is applying a global expenses policy without accounting for these local nuances, your UK business could be exposed to unnecessary tax liabilities, enquiries from the tax authorities, and penalties.

Reimbursing Expenses: The Basics

Travel expenses are business costs incurred by employees while performing their job duties. In the UK, there are two criteria that must be fulfilled for a tax-free reimbursement:

  1. Travel in the performance of duties (e.g., a sales rep visiting clients), AND
  2. Travel to a temporary workplace (e.g., a project site outside their normal commute).


Personal travel or commuting to a permanent workplace cannot be reimbursed tax-free.

Round Sum Allowances and Scale Rates

The UK does allow for tax-free round sum payments known as scale rate payments, but they are very modest compared to other countries.

Benchmark Rates:

Minimum Journey TimeMaximum Allowance
5 hoursGBP 5
10 hoursGBP 10
15 hours + after 8pmGBP 25

A supplementary GBP 10 can be added if the journey extends beyond 8pm. But crucially:

  • Receipts must be retained.
  • Payments must meet all qualifying conditions.

Bespoke Scale Rates

If you want to use higher rates that reflect actual costs, you can apply to HMRC for approval. This requires:

  • A sampling exercise of actual expenses (e.g. 10% of employees over one month).
  • Evidence that the proposed rates are reasonable and represent real costs.

What If You Don’t Follow the UK Rules?

Reimbursing employees outside of the approved framework could result in:

  • The need to treat payments as taxable income.
  • PAYE and National Insurance liabilities.
  • Penalties and interest from HMRC.


We understand that you’re under pressure to standardise systems across the group. But in the UK, compliance requires localisation.
