Not many people actually enjoy reconciling business travel expenses. Keeping track of receipts for incidental purchases and meals on the road can tax even the most organised of workplace travellers. For travel managers and finance teams, collating and checking expense claims up takes time and effort that could be better spent on more productive tasks.   Per diem pay, a flat rate paid to your travelling employees in lieu of individual expenses can solve some of these paperwork problems. But, is it better than claiming for expenses the traditional way? Let’s explore more in this blog. TL:DR Per diem pay is a daily allowance for business travel expenses, covering incidental expenses like food and drink. It simplifies expense management, provides predictable budgeting, and saves time.  Common in industries like construction, engineering, transportation, and consulting, per diem rates are set by HMRC and vary by location and travel duration.  Compared to claiming individual expenses, per diem pay saves time for both employees and finance departments, making it generally more efficient.

That means the expense claims you deal with are also set to increase. So, how do you manage business travel expenses? Traditionally, there are two ways: Your employees pay for incidentals like parking fees or permits, meals, and other expenses on the go. They keep all their receipts, submit an expense claim, then await reimbursement in the next payroll.  You pay your employees a flat fee per day a per diem rate for subsistence and incidentals.    Per diem meaning Per diem, a Latin term meaning “per day,” refers to the daily allowance given to employees for business travel expenses. This allowance covers the cost of necessary meals, as well as incidental expenses that might arise, such as car parking fees or entry tickets.  By pooling those costs into one specified daily lump sum, per diems simplify the process of managing travel costs for both the employer and the employee.   Which industries typically use per diem pay? Per diem pay is widely used across various industries, but it is particularly prevalent in those where employees are expected to travel domestically, regularly and on a standard budget. Key sectors include: Construction: Workers are frequently required at different sites, with multiple ongoing projects to oversee. They usually require standard allowances for their daily expenses. Engineering: Engineers on field assignments benefit from predictable daily allowances. Transportation: Truck drivers and other logistics personnel use per diem to cover their costs when on the road. Consulting: Consultants travelling to client sites often receive per diem pay to manage their subsistence costs efficiently.   How to calculate per diem pay Calculating per diem pay involves several factors: Determine the rate: Per diem expenses rates are set by HMRC or negotiated with HMRC by an individual company. These rates vary by location i.e. whether travel is to the UK or abroad and by the duration of travel.  Number of days: Multiply the per diem rate by the number of days spent on travel. Partial days: Adjust the calculation for partial travel days or specific meals provided.   Current per diem rates in the UK Per diem rates in the UK are set by HMRC.

HMRC guidelines on per diem allowance for travel and subsistence HMRC uses the scale rates to make it easier for you and your employees to manage business travel expenses. However, to make sure you keep everything above board, there are a few rules and regulations you’ll need to follow.  To use benchmark scale rates, the travel must have a business purpose i.e. be in the performance of the employee’s duties or to a temporary place of work. The workforce traveller must be away from their normal place of work or home for more than five or ten hours, depending on the rate applied, and must have incurred a cost on a meal after starting the journey. A meal is defined as a combination of food and drink. Employees can claim up to three meal rates in a 24-hour period. There is no set benchmark rate for overnight subsistence. Employers and employees need to agree on a reasonable rate if applicable. If the cost of a meal (such as breakfast or an evening meal) is reimbursed on an actual basis, the employee cannot claim the scale rate for that meal.   Per diem vs. traditional expense claims The benefits of per diem pay Simplifies expense management Because employees receive a fixed daily..
