Key items to include on your tax return include income sources (W-2s, 1099s), and various deductions and credits to lower your tax liability. Key deductions include mortgage interest, state and local taxes (SALT), charitable donations, student loan interest, and IRA contributions. Self-employed individuals can deduct business expenses, home office costs, and health insurance premiums.
You can write off common expenses like student loan interest, retirement contributions (IRA/401k), self-employed health insurance, and business-related costs (home office, mileage, supplies) if you're an employee or self-employed, but itemizing deductions for things like medical expenses (over 7.5% AGI), mortgage interest, and charitable donations only pays off if it exceeds the Standard Deduction. Self-employed individuals have many more write-offs, including professional dues, business meals, and equipment, but always keep meticulous records.

The biggest tax mistakes people make include filing late, math errors, incorrect personal info (like Social Security numbers), forgetting deductions/credits (like EITC), misreporting income, not signing forms, and making errors with bank details for direct deposit, all leading to delays, penalties, or missed savings, with using tax software or professionals helping avoid these common pitfalls.
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. It's an option to replace itemised work-related deductions, not an extra refund, and doesn't affect non-work-related deductions like charity.
For example, many freelancers who rely heavily on home internet may deduct 50% or more of their internet bill. Light work use would require a lower percentage. Keep in mind that if you are a W-2 employee, you cannot deduct any portion of your home internet bill from your taxable income, even if you work from home.

Many business expenses are 100% deductible, including advertising, employee wages, rent, supplies, and certain business meals like company parties or meals for the public, while personal deductions like student loan interest or charitable donations (depending on the type) can also be fully deductible for individuals. The key is that the expense must be "ordinary and necessary" for your trade or business or meet specific IRS criteria, often differentiating from the 50% rule for client meals.
