Start with what your job actually requires

A teacher buying classroom materials and an engineer paying for professional training may have very different claims. Start with the expense and your duties. Write down what you bought, how it helps you do your current work and whether your employer covered any of the cost.

Professional expenses need individual checks. Self-education expenses may qualify when study maintains or improves skills used in your current work. A course designed to help you enter a new occupation generally does not qualify on that basis. Keep the course outline alongside the invoice.

Separate the work portion before claiming

Suppose you pay $240 for a subscription and your records support 75% work use. If the expense otherwise qualifies, the work-related claim is $180. This is an illustration, not an automatic percentage you can use for your own expenses.

A receipt proves you paid, but it may not explain your work use. Keep a short diary or another reasonable record of that split. Equipment may need to be claimed over its useful life rather than deducted in full when you buy it.

Check the items that are easy to misunderstand

Ordinary office outfits remain conventional clothing, even when your employer expects you to dress professionally. Different rules can apply to protective clothing and eligible uniforms.

Before lodging, put your receipts, reimbursement details and work-use calculations together. Flag anything you’re unsure about. A clear explanation now makes the claim easier to review later.
