• Total amount of expenses for each category
• Number of meals and lodging days

Employers should also maintain records of:

Employers should ensure that records are kept for at least three years in case of an audit.

• Keeping records for at least two years
• Using a standardized format for recording expenses
• Maintaining accurate and detailed records

Common Pitfalls to Avoid with Reimbursement Programs

Here are some potential pitfalls to watch out for:

• Insufficient documentation: Failure to keep accurate and detailed records of employee expenses can lead to disputes and potential audits. Make sure to maintain a thorough record of receipts, invoices, and other supporting documentation.
• Inadequate accounting: Without proper accounting and tracking of expenses, it can be challenging to ensure that reimbursements are made in accordance with accountable plan requirements. Consider investing in accounting software to streamline the process.
• Misclassification of expenses Ensure that all expenses are properly classified and accounted for.
• Lack of transparency: Not providing clear and transparent information about employee expenses can lead to confusion and disputes. Make sure to clearly communicate the purpose and criteria for reimbursing employee expenses.
• Inadequate employee education: Failing to educate employees about the reimbursement program and the rules governing expenses can lead to misunderstandings and potential disputes. Provide clear and concise information about the program and its requirements.
• Insufficient communication: Not communicating clearly and effectively with employees and management about the reimbursement program can lead to confusion and potential disputes. Establish a clear and transparent communication plan to ensure everyone is on the same page.

When to Use Employee Expense Reimbursement through Payroll

Employee expense reimbursement through payroll is a tax-efficient way for small business owners to reimburse their employees for business-related expenses. However, it's essential to understand the rules and requirements to avoid any potential pitfalls.

Here are some key scenarios where employee expense reimbursement through payroll is a good idea:

• Business use of a personal vehicle
• Home office expenses: For S corporation owners, home office expenses must be reimbursed using actual expenses, excluding the $5 per square foot simplified method. This means that employees cannot claim a flat rate for home office expenses, such as rent or utilities.
• Reimbursement for lodging: Employees must provide contemporaneous records showing the date, amount, business purpose, and business connection for each lodging expense. Receipts are generally required for expenses of $75 or more.
• Quarterly statements: Quarterly statements can be used to provide a 120-day window for employees to claim reimbursement for expenses.

• A business connection: The employer and employee must be related in some way, such as co-owners or partners.
• Adequate substantiation of expenses: The employer must provide sufficient documentation to support the expense reimbursement, including receipts, invoices, and bank statements.
• Return of excess reimbursement within a reasonable time: The employer must return any excess reimbursement to the employee within a reasonable time after the expense is reimbursed.
