Understanding per diem pay: a comprehensive guide for employers

Business trips are full of opportunities, but they can be tricky to manage. There is a lot to organize: booking hotels, arranging flights, and planning schedules. Plus, you must keep track of all expenses.

To make things simpler, consider using per diem — a straightforward way to handle costs during business trips. It saves time on paperwork and makes expenses easier to handle.  But how does per diem work? This article is the answer.

What is Per Diem?

Per diem is a daily allowance you give to employees for their work trips. It means "for each day." You give them a set amount of money to cover hotel stays, meals, and other expenses. Sometimes, per diem only covers meals and small expenses.

Employees like per diem because they do not have to spend their own money when they travel for work. But it is not mandatory for companies to provide per diem to employees.

Exploring Various Per Diem Types

Here is a breakdown of the different types of per diem:

  • Government Per Diem: These are standard rates set by the U.S. GSA (General Services Administration) for federal employees. Other businesses sometimes use these rates too.
  • Corporate Per Diem: Businesses provide these allowances to their employees. The rates can be different from government rates based on what the company decides.
  • International Per Diem: When employees travel outside the U.S., businesses give them international per diem rates. These rates are adjusted to match the costs in different countries.

Each type of per diem serves a specific purpose, ensuring employees have enough money to cover expenses while they are away from home.

How Employers Calculate Per Diem

Employers figure out per diem using guidelines from the U.S. General Services Administration (GSA). These guidelines set the standard rates for federal employees. Many companies use these rates to decide on their own per diem rates.

Here is how employers calculate per diem:

  • Standard Rates: The GSA sets standard federal rates per diem. Government employees get these rates.
  • High-Low Method: Some companies use the high-low method. This method sets both a high and low per diem rate for different locations. When an employee is in an expensive area, they get the higher rate. For cheaper areas, they get the lower rate.

When Do Employees Get Per Diem?

Employees usually get per diem at the start of a business trip. This can be a check or a company credit card. With the company card, they spend a set amount for travel expenses. Not having these means they can use their own money instead and get reimbursed later.

How Per Diem Works

How per diem works mostly depends on you or your company's travel policy. When you are on a trip for work, you do not have to show receipts for every little thing you buy. But you must keep track of what you spend. This way, when you do your taxes, you can deduct these expenses.

You will need to fill out an expense report. This report must have:

  • The date, place, and times of your expenses.
  • Why do you spend the money (like for a meeting or conference).
  • Whether the money was for a place to stay or just for food and other small things.

Make sure to turn in this report within 60 days. Submit it later and the money you got for per diem becomes taxable income.

Some companies give per diem money to employees before they travel. This is good because then the employees do not have to use their own money or carry a big balance on their credit cards. Other companies give the money after the trip. Either way is fine, as long as you are fair about it.

You can also decide whether your employee can keep any leftover per diem money. It does not really make sense to ask for it back if they did not spend it all. Plus, it is a nice little bonus for the hard work of traveling for work.

Exploring Per Diem Guidelines

Business trips can be exciting and good for a company's growth. When done right, they can make employees happy and more dedicated. So, it is important for a company to make traveling a positive experience for their workers.

Here are some ways companies can make business travel better:

  • Offer a good amount of per diem money. Giving employees enough money to cover their expenses, or at least a fair amount.
  • Give corporate credit cards to employees. This way, they do not have to use their own money for work expenses, which can affect their taxes.
  • Use technology to make things easier. Companies can use smart tools to automate expense reports and give back per diem money faster.
  • Make per diem policies clear and easy to follow. Employees must not have to remember complicated rules about what they can spend money on or how much they can spend on lodging.
  • Keep employees safe. Make sure there are rules in place to protect employees when they are traveling.
  • Make booking trips and getting help during travel as simple and enjoyable as possible.

Per diem is a fixed sum of money employees get for each day they are on business trips. Using per diem rates instead of paying for each thing separately can save a lot of paperwork.

Employers can make up their own per diem rates, but many sticks to the rates set by the government. When employees get more money back than the government suggests, that extra cash counts as taxable income.
