Expense Reimbursement Policy

An expense policy defines what the company will pay for, how employees get reimbursed, and what documentation is required — preventing disputes and ensuring tax compliance.


What is a Expense Reimbursement Policy?

An Expense Reimbursement Policy creates a shared understanding between employer and employee about what business expenses the company will cover, how to seek approval before incurring an expense, and how to submit and process a claim. Without a clear policy, disputes arise about what was agreed and what the company considers a legitimate business expense.

From a tax perspective, a documented expense policy is important for substantiating deductions. The ATO requires businesses to retain records of business expenses, and a policy that requires receipts and describes the business purpose of categories helps establish that deductions are legitimate.

When do you need a Expense Reimbursement Policy?

  • When employees begin travelling for business or entertaining clients
  • When scaling the team and needing consistent financial controls
  • When reviewing finance processes as part of a policy refresh
  • Before engaging contractors or remote employees who incur business expenses

Common mistakes to avoid

1

Not specifying a GST tax invoice threshold ($82.50 is the ATO threshold requiring a valid tax invoice)

4

Reimbursing without receipts and then facing ATO scrutiny during an audit

Frequently asked questions

What receipts do I need to keep for business expenses in Australia?

The ATO requires a tax invoice (not just a receipt) for any business purchase over $82.50 including GST. For amounts under $82.50, a simple receipt is sufficient. All records should be retained for at least 5 years. Your expense policy should require employees to submit original receipts or clear digital copies within a specified timeframe.
