According to section 110.7 and regulation 7304, the maximum deduction that can be claimed for any eligible trip is the least of (1) the taxable travel benefit from employment received for that trip; (2) the total travel expenses paid for the trip; and (3) the cost of the lowest return airfare (LRA) available at the ...

Adrienne buys deductible work-related books from an international retailer and is charged an international transaction fee by her bank. Because the books are a work-related expense, Adrienne can also claim the cost of the international transaction fee imposed by her bank.

Fares for taxis or other types of transportation between an airport or train station and a hotel, or from a hotel to a work location. Shipping of baggage and sample or display material between regular and temporary work locations. Using a personally owned car for business.
100% write-offs, primarily through bonus depreciation, allow businesses to immediately deduct the full cost of qualifying new and used assets (like equipment, machinery, vehicles, and certain improvements) in the year they're placed in service, rather than depreciating them over years, significantly boosting cash flow and lowering taxes, with recent laws making this 100% deduction permanent for assets acquired after January 19, 2025. This is a major tax incentive under recent legislation, often used alongside Section 179 expensing, which offers its own high deduction limits, notes Forbes.
The "$1000 instant tax deduction" refers to a proposed Australian tax policy, specifically from the Albanese Labor government in 2025, allowing eligible workers to claim a flat $1,000 deduction for work-related expenses without needing receipts, simplifying tax returns for those with lower expenses but potentially costing those with higher expenses, starting from 1 July 2026.

The section 179 deduction allows taxpayers, other than trusts and estates, to elect to expense a specified amount of the cost of qualifying property purchased for use in a business. For tax years beginning in 2026 the maximum deduction is $2,560,000, (2025, the maximum deduction is $2,500,000).
Allowable expenses include your basic office costs such as stationery and the bills you pay on your business phone. Travel costs and staff salaries are also included, as is the cost of a uniform or other appropriate clothing (for example, if you work in a skilled or manual trade).
Math mistakes.
Math errors are some of the most common mistakes. They range from simple addition and subtraction to more complex calculations. Taxpayers should always double check their math. Better yet, tax prep software does it automatically.
