Self-employed deductions are business costs that can reduce taxable profit when they are ordinary, necessary, properly recorded, and allowed for the situation.
Quick answer
Common self-employed deductions can include mileage or vehicle expenses, supplies, phone and data, software, home office where allowed, insurance, professional fees, advertising, education, payment processing, and business travel. The record should show what was bought, when, how much it cost, why it was business-related, and whether personal use was split out.
Vehicle and mileage costs
Vehicle records often matter most for mobile businesses. For 2026, the IRS business standard mileage rate is 72.5 cents per mile. Actual vehicle expenses can include fuel, charging, maintenance, repairs, insurance, registration, lease costs, depreciation, tolls, and parking where allowed. Actual expenses require total vehicle use and business-use percentage.
Parking and tolls need separate support. Parking for a client meeting, supplier pickup, or job site may be deductible when the trip is business-related. Parking tickets and fines are different and should be reviewed carefully.
Home office and workspace
The home office deduction is specific. IRS Publication 587 says business use of part of a home must generally meet regular and exclusive use rules and other requirements. Keep measurements, photos, rent or mortgage records, utilities, and business-use notes before claiming.
The simplified home office method can make recordkeeping easier, but it does not remove the need to prove that the space qualifies. The regular method needs stronger expense records because it uses actual home costs and business-use percentage.
Phone, software, and subscriptions
A phone bill, cloud storage subscription, accounting app, mileage tracking app, payment tool, booking software, and business email service may be partly business and partly personal. Keep a business-use percentage and review it when the business changes.
Supplies and services
Supplies, tools, materials, postage, shipping, packaging, cleaning, office supplies, job materials, professional fees, legal help, bookkeeping, and tax preparation can be relevant when tied to business activity. Larger equipment may need depreciation or capitalization review.
Startup costs can matter for a new business. Market research, pre-launch advertising, consultant fees, setup travel, and training before opening may need separate treatment from normal operating expenses. Keep them in their own category so a preparer can decide how they should be handled.
Travel, meals, and lodging
Business travel records should show where you went, why the trip was business-related, who was involved, and what was paid. Save airfare, hotel, rental car, rideshare, parking, tolls, conference, and client-meeting records. Meals usually need extra care because personal meals and entertainment-style expenses can look similar to business meals. Keep the receipt, the business purpose, and the people involved.
Advertising, professional fees, and insurance
Advertising, website costs, directory listings, design help, business cards, paid search, professional dues, accounting, legal advice, tax preparation, liability insurance, business auto insurance, and workers’ compensation can all be relevant depending on the business. The record should show the business purpose and whether the cost was for the current year, a future period, or a capital asset.
Interest, fees, and financing costs
Business loan interest, credit card interest on business purchases, bank fees, processor fees, and financing charges can be deductible when they belong to the business. Mixed personal and business cards are harder to support. A dedicated business account or card makes this category cleaner.
Retirement and health insurance
Self-employed retirement contributions and health insurance deductions can be valuable, but they have eligibility rules, contribution limits, plan documents, and income limits. Keep plan statements, insurance payment records, and eligibility notes. These items are easy to overstate if they are treated like ordinary receipts.
Deductions that need caution
Meals, clothing, home office, education, health insurance, retirement contributions, gifts, large equipment, and reimbursed expenses can have limits or special rules. Save the record, but do not assume every category applies to every taxpayer.
Deduction quality test
Before keeping a deduction, ask:
- Is there a receipt, invoice, statement, or log?
- Is the business purpose clear?
- Is personal use separated?
- Was the cost reimbursed?
- Does the category fit the business?
- Can the amount be matched to bank or payment records?
Deduction examples by business type
A rideshare or delivery contractor may focus on mileage, phone, platform supplies, tolls, parking, cleaning, roadside assistance, and tax preparation. A consultant may focus on software, home office, client travel, professional subscriptions, phone, education, insurance, and payment processing. A tradesperson may need tools, supplies, job-site mileage, equipment, insurance, licensing, and subcontractor records. An online seller may need inventory, shipping, marketplace fees, packaging, returns, advertising, and storage.
The right deduction list follows the business model. A category that is common for one business can be irrelevant or risky for another.

Standard mileage vs actual vehicle expenses
Vehicle deductions deserve their own decision. The standard mileage method is simpler because the rate converts documented business miles into a deduction. Actual expenses require receipts and the business-use percentage of total vehicle use. Actual expenses may make sense for some expensive vehicles, high operating costs, or low total mileage, but they also require stronger bookkeeping.
Do not wait until tax season to decide. Keep both mileage and vehicle expense records during the year when possible. Then the owner or preparer can compare methods where rules allow.
What makes a deduction stronger
A strong deduction has four pieces: the proof of payment, the proof of what was purchased, the business purpose, and the allocation if personal use exists. A receipt without a business purpose is weaker. A business-purpose note without a receipt is also weaker. The best record combines both.
Red flags to review carefully
Review deductions that look personal, unusually large, inconsistent with revenue, duplicated by reimbursement, or unsupported by receipts. Home office, meals, clothing, gifts, vehicle costs, travel, and education often need more context than a simple category label.
FAQ
What deductions do self-employed people commonly miss?
Commonly missed records include business mileage, parking, tolls, phone and software use, payment processor fees, professional fees, supplies, insurance, and small recurring subscriptions.
Can I deduct clothing?
Only review clothing that is specifically required for the business and not suitable for normal personal wear, such as certain uniforms or safety gear. Ordinary clothing and grooming are usually weak deductions.
Can I deduct education?
Education is strongest when it maintains or improves skills for your current work. Training for a new trade or personal interest needs careful review.
Should I use standard mileage or actual vehicle expenses?
Keep both mileage and vehicle expense records during the year when possible. Then compare methods where rules allow. The standard mileage method needs a strong mileage log; actual expenses need receipts and total vehicle-use records.
