International per diem rates
International travel involves different per diem rates than domestic corporate travel. Per diem rates depend on the standard cost of business travel to a foreign area and are influenced by the cost of living at the destination. The relevant governing bodies, such as His Majesty’s Revenue and Customs (HMRC) determine domestic and international rates. Per diem rates vary depending on where you’re going. Whether you're travelling to Australia, France, Germany, or Japan— there are unique international per diem rates for every destination. Read on to learn how to navigate per diem allowances for international travel on business trips from the UK.How per diem rates for foreign travel are established in the UK
The UK government, specifically HM Revenue & Customs (HMRC), sets the domestic and foreign per diem rates. These rates are known as "benchmark scale rates" or "meal allowance rates". According to the most recent official information, the current domestic per diem rates are:- £5 for trips for 5 hours or more.
- £10 for trips for 10 hours or more.
- £25 for trips for 15 hours or more and ongoing at 8 pm.
- Additional £10 if travel is ongoing at 8 pm on a trip of 5 or 10 hours.
Now let’s look at the international per diem rates for some common business destinations:What’s covered under per diem rates?
Per diem rates cover meals and incidental expenses—like coffee or snacks—during business trips. However, accommodation and travel expenses, such as fuel or train tickets, are not included. These items need to be claimed separately or reimbursed through alternative channels like: - Corporate credit cards: Many companies provide corporate credit cards for employees to use for business travel expenses. These charges are then reviewed and approved separately from per diem claims.
- Direct billing: Some organisations have arrangements with hotels or travel agencies where the company is billed directly for accommodation and major travel expenses.
- Travel management systems: Companies often use specialised travel management platforms like TravelPerk where employees can book travel and accommodation. These systems track expenses separately from per diems.
- Mileage claims: For fuel expenses when using personal vehicles, employees typically submit mileage claims using HMRC-approved mileage rates.
- Pre-paid bookings: In some cases, the company may pre-book and pre-pay for accommodation and travel, so the employee doesn't need to claim these expenses at all.
- Reimbursement through payroll: Some organisations process larger travel expenses like accommodation through the payroll system rather than the standard expense claim process.
How are international per diem rates taxed?
As long as the per diem payments align with the HMRC-approved rates and the qualifying conditions are met, they are entirely tax-free. This means:- Employees won’t owe income tax on these payments.
- Employers won’t need to make National Insurance contributions on them.
If payments exceed these approved rates or fail to meet the necessary conditions, the extra amount becomes taxable and must be reported on the employee’s P11D form. This could result in higher tax liabilities for both the employer and the employee, so careful management of per diem rates is crucial.Employers may need to submit a P11D(b) form, which calculates the National Insurance contributions on the benefits provided.The HMRC always requires expense reports. Expense reports must be filed for every instance of expenditure, showing the time, place and purpose of the business trip. Set your custom HMRC-compliant foreign per diem rates
While HMRC provides clear guidance on meal allowances, there is no fixed rate for overnight accommodation costs. For companies with frequent travellers, you can set up custom HMRC-compliant per diem rates, especially for destinations with high accommodation costs, such as London or Iceland. Here's how you can do it:- Visit the official HMRC website.
- Look for the section related to employer expenses and benefits or scale rate payments.
- Accessing the form through this general link for HMRC forms:
This page mentions an "employers exemption form" that can be used to apply for a new bespoke scale rate for reporting non-taxable expenses and benefits.If you're unable to locate the form online, it's recommended to contact HMRC directly. They can provide you with the most up-to-date information on how to submit an application for bespoke per diem rates.Remember, when applying, you'll need to:- State the rate you wish to pay
- Prove that the amount is a reasonable estimate of actual expenses incurred by employees. You can do this with a sampling exercise. This involves randomly selecting about 10% of eligible employees and tracking their expenses for one month. The data from this sample must provide a clear and reasonable estimate of the typical expenses incurred during business travel.
- Show that you have a checking system in place to ensure payments are only made when employees are entitled to them and have actually incurred the expenses.
