Tax season can be challenging for small business owners and self-employed professionals, especially when records are spread across bank statements, receipts, and apps. Reviewing potential small business tax deductions throughout the year can make filing more organized and help ensure eligible business costs are considered. The examples below are general U.S.-focused information; eligibility and rules depend on your business, location, and tax year.
10 Small Business Tax Deductions to Review
1. Business Vehicle Use
If you use a vehicle for business, you may be able to deduct eligible business-use costs. Depending on the applicable rules, this may involve a standard mileage method or actual vehicle expenses. Keep a timely mileage log that records the date, destination, business purpose, and miles driven. Tolls and business parking fees may also qualify as travel expenses, so save those receipts separately.
2. Office and Home Office Costs
Rent for a business office or studio may be deductible when it is an ordinary business expense. A home office may qualify if it meets the relevant requirements, which commonly include regular and exclusive business use of a designated area. Keep records of the space and related household costs, and check the rules before allocating a share of rent or other expenses.
3. Business and Office Supplies
Common business purchases can include computers, cameras, printers, printer supplies, stationery, software, postage, apps, web hosting, and platform fees. Save receipts and note the business purpose of each purchase. Higher-cost equipment used over several years may need to be depreciated rather than deducted all at once; ask a tax professional how to treat those assets.

4. Education and Professional Development
Some education expenses may qualify when they meet the tax rules for your work or business. Keep records of tuition, fees, course materials, and related payments. Before claiming an expense, confirm that the course qualifies for your situation; education deductions and credits have specific requirements and are not interchangeable.
5. Insurance Premiums
Depending on eligibility, self-employed people may be able to deduct health insurance premiums, and businesses may be able to deduct certain business insurance costs. Coverage for a rented office or a company vehicle may also be relevant. Keep policy documents and proof of payment, and check whether the expense is personal, business-related, or subject to special limitations.
6. Advertising and Promotion
Costs for promoting a business may include mailers, advertising services, and email marketing platforms. Retain invoices and payment records, and make sure the expense relates to promoting your business. A clear description in your bookkeeping can help distinguish advertising costs from personal or unrelated spending.
7. Banking and Payment Processing Fees
Monthly account charges and payment processing fees can be easy to overlook, particularly when they are automatically deducted. Review statements for business bank and payment-platform fees, and record them in your books. Using a separate business account can make these costs easier to identify.
8. Retirement Plan Contributions
Eligible employer contributions to employee retirement plans may be deductible, subject to plan and tax rules. Contributions made by a self-employed person are handled differently and may have limits or special calculation requirements. Keep plan statements and contribution records, and confirm the treatment for the specific plan and tax year.
9. Tax Preparation and Accounting Fees
Fees for tax preparation, bookkeeping, or professional advice may qualify as business expenses when they relate to business matters. Separate business services from personal tax work on invoices where possible. A qualified tax professional can also help review records and identify documentation gaps before filing.
10. Work-Related Moving Costs
Moving expenses are subject to significant restrictions, and eligibility depends on current law and personal circumstances. The 50-mile distance test and the 39-week employment or 78-week self-employment time tests have appeared in specific rules, but they are not a universal guarantee that moving costs are deductible. Check the rules for the relevant tax year and keep moving invoices if you think an exception may apply.
Make Recordkeeping Part of Your Routine
Good records make it easier to support small business tax deductions if questions arise. Save receipts, mileage logs, invoices, and statements in an organized digital or paper system, and reconcile them with your bookkeeping regularly. Keep personal and business spending separate where practical, and ask a tax professional about uncertain or high-value expenses. Consistent recordkeeping throughout the year can make tax preparation more manageable.
