Common tax-deductible expenses that reduce taxable income include mortgage interest, property taxes, state and local taxes (SALT), charitable donations, and medical expenses exceeding 7.5% of adjusted gross income. Self-employed individuals can deduct home office, vehicle, and business-related costs. Others include retirement contributions, student loan interest, and HSA contributions.
You can deduct these expenses whether you take the standard deduction or itemize:

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.
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.
The IRS allows taxpayers to deduct up to $3,000 of realized investment losses ($1,500 if married filing separately) against ordinary income each year. This deduction applies only to losses in taxable investment accounts and must be realized by December 31st to count for that tax year.
What Are Allowable Expenses? An allowable expense is money spent by your employees to conduct company business. These expenses are eligible for reimbursement under company policies. Examples include business travel, business meals, and purchasing goods or services necessary for work.
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).
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. It's an option to replace itemised work-related deductions, not an extra refund, and doesn't affect non-work-related deductions like charity.
The IRS $600 rule refers to a change in reporting requirements for third-party payment apps (like Venmo, PayPal) for taxable income from goods and services, where platforms must send a Form 1099-K if you receive over $600 in a year, intended to capture gig economy/side hustle income, though delays and phased implementation have adjusted the timeline, with current rules for 2024 using a higher threshold ($5,000) before fully phasing to $600 for future years, but remember all taxable income, regardless of form, must always be reported.
