You can claim tax-deductible work expenses if they are ordinary, necessary, and unreimbursed by your employer, such as business travel, specialized uniforms, tools, union dues, and home office costs. Self-employed individuals have a broader range of deductible expenses, including marketing, professional fees, and business-related meals.
At tax time, you may be able to claim certain work and income-related expenses to lower your taxable income. Common deductions can include home office costs, work travel, uniforms, education expenses, gifts, donations and some investment-related costs.

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.
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.

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).
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.

Business expenses you can report if you're self-employed
Errors in Social Security numbers, names, or addresses are surprisingly common. Double-check all personal information on your forms and make sure it matches official records. Failing to include all W-2s, 1099s, or receipts for deductions can trigger audits or processing delays.
Cell phones and internet deductions
