Every receipt you forget to claim costs you twice. You pay income tax on it, and then you pay another 15.3% in self-employment tax on top. For a freelancer in the 22% bracket, a missed $1,000 expense can easily cost $300 or more.
This self-employed tax deductions checklist follows the actual IRS forms, line by line. It covers the Schedule C expenses you report against your business income, plus the deductions that live on other forms and get skipped most often. All figures are current for the 2026 tax year, including the mileage rate change that took effect on July 1, 2026.
Use it now to clean up your books before December 31, then again when you file in 2027.
- Schedule C expenses: Ordinary and necessary business costs such as software, supplies, insurance, contract labor, travel, 50% of business meals, and vehicle use.
- Home office: Up to $1,500 with the simplified method, or actual costs on Form 8829, if the space is used regularly and exclusively for work.
- Above-the-line adjustments: Half of your self-employment tax, self-employed health insurance, and SEP or Solo 401(k) contributions.
- QBI deduction: Up to 20% of qualified business income, now permanent under the 2025 tax law.
How to Use This Self-Employed Tax Deductions Checklist
Self-employed deductions land in three different places on your return. Most freelancers only work through the first one, so the other two get missed.
- Schedule C (Profit or Loss From Business): Your business expenses. These lower both your income tax and your self-employment tax.
- Schedule 1 (Adjustments to Income): Half of your self-employment tax, health insurance premiums, and retirement contributions. These lower your income tax and your Adjusted Gross Income (AGI), which is your total income minus these adjustments.
- Form 8995 or 8995-A: The Qualified Business Income (QBI) deduction, taken after AGI is figured.
Every Schedule C expense has to pass the same test. The IRS calls it “ordinary and necessary,” meaning the cost is common in your line of work and helpful for running it. Personal costs fail the test, even if you sometimes use the item for work.
The IRS Self-Employed Individuals Tax Center lists the forms and publications behind each rule below. If you run a business with employees or inventory, our small business tax deductions checklist covers payroll and cost of goods sold in more depth.
Schedule C Expense Checklist, Line by Line
Go down this table with your bank and card statements open. Tick each line you have expenses for, then total them by category.
| Schedule C Line | What Counts | Watch Out For |
|---|---|---|
| 8. Advertising | Website hosting, domain names, paid social ads, business cards, portfolio sites | Personal social accounts don’t count |
| 9. Car and truck | Business miles at the standard rate, or the business share of actual costs | Commuting to a regular workplace is never deductible |
| 10. Commissions and fees | Payment processor fees, marketplace and platform fees, agent commissions | Report gross income first, then deduct the fees |
| 11. Contract labor | Subcontractors, virtual assistants, freelance editors or designers | Collect a Form W-9 before you pay anyone |
| 13. Depreciation and Section 179 | Laptops, cameras, tools, furniture, and other equipment | Business-use percentage must be documented |
| 15. Insurance (other than health) | General liability, professional liability, business property coverage | Health insurance goes on Schedule 1, not here |
| 16b. Other interest | Interest on business loans and business credit cards | Interest on personal cards used for mixed spending gets messy |
| 17. Legal and professional services | Tax preparation for your business, bookkeeping, attorney fees for contracts | Only the business part of your tax prep bill counts |
18. Office expense |
Postage, printer ink, small office items, software subscriptions | Some preparers list software under “Other expenses” instead |
| 20b. Rent or lease (other property) | Coworking memberships, studio or storage unit rent, equipment rental | Rent on your home belongs in the home office deduction |
| 22. Supplies | Materials used up in your work, small tools, craft or job-site supplies | Keep receipts that show what was bought |
| 23. Taxes and licenses | State and city business licenses, professional license renewals | Federal income tax and SE tax are not deductible here |
| 24a. Travel | Airfare, lodging, and rideshares on overnight business trips | The trip must take you away from your tax home overnight |
| 24b. Deductible meals | 50% of meals with clients or while traveling for work | Entertainment, such as concert or game tickets, is 0% deductible |
| 25. Utilities | Business share of your cell phone and internet | Home utilities belong in the home office deduction |
| 27a. Other expenses | Courses that improve your current skills, trade dues, bank fees, business gifts up to $25 per person | List each item by name in Part V |
Line numbers follow the current Schedule C. The IRS occasionally shifts them, so match the category names if your form looks slightly different.
Two Rules That Simplify Equipment Purchases
Under the de minimis safe harbor, you can expense items costing $2,500 or less per invoice or item right away. You make the election with a short statement attached to your return.
Bigger purchases can still be written off in year one. The 2025 tax law permanently restored 100% bonus depreciation for qualifying property acquired after January 19, 2025. For 2026, the Section 179 limit is $2,560,000, far above what any solo business will hit.
Deductions by Type of Self-Employed Work
The same Schedule C lines look different depending on what you do. Use these examples to spot items your trade commonly misses.
- Writers, designers, and developers: Software and font licenses, stock photo subscriptions, cloud storage, a second monitor, and portfolio hosting.
- Rideshare and delivery drivers: Mileage between trips, phone mounts, chargers, insulated bags, and the business share of your phone plan.
- Tradespeople and contractors: Hand tools, safety gear, job-site supplies, liability insurance, and trade license renewals.
- Coaches and consultants: Scheduling and video software, professional certifications, coworking space, and client meeting meals at 50%.
- Creators and sellers: Platform fees, props and materials used in content, shipping supplies, and equipment like cameras and lighting.
Vehicle Costs: The 2026 Mileage Rate Changed Mid-Year
This is the line where most freelancers leave money behind, and 2026 adds a wrinkle. The IRS set the business rate at 72.5 cents per mile on January 1. Citing higher fuel prices, it raised the rate to 76 cents for miles driven from July 1 through December 31, 2026.
That split means your mileage log needs dates, not just a yearly total. You’ll multiply first-half miles by 72.5 cents and second-half miles by 76 cents. The official figures sit on the IRS standard mileage rates page.
Standard Mileage or Actual Expenses?
You can claim either the standard rate or the business share of real costs. Actual costs include gas, insurance, repairs, registration, lease payments, and depreciation.
- Standard rate works best for fuel-efficient cars and drivers who log a lot of miles.
- Actual expenses work best for trucks, vans, and newer vehicles with high depreciation.
- The first-year rule matters. To use the standard rate on a car you own, you generally have to choose it in the first year the car is used for business.
- Parking and tolls for business trips are deductible under both methods.
Your log should show the date, starting point, destination, business purpose, and miles for each trip. A phone app that records trips automatically counts, as long as you add the purpose.
Home Office Deduction: Simplified or Regular Method
The home office deduction applies when part of your home is used regularly and exclusively for business. A desk in the guest room that guests also use doesn’t qualify. By contrast, a spare bedroom set up only as your office does.
The simplified home office option gives you $5 per square foot, up to 300 square feet. That caps the deduction at $1,500, with no utility bills to add up.
The regular method, filed on Form 8829, takes your office’s share of rent or mortgage interest, utilities, insurance, and repairs. A 200-square-foot office in a 1,600-square-foot apartment is 12.5% of the space. At $2,000 a month in rent, that’s $3,000 a year in rent alone, double the simplified cap.
Run both numbers before you choose. Renters in high-cost cities usually come out ahead with the regular method.
Above-the-Line Deductions Most Freelancers Miss
These three items never appear on Schedule C. That’s exactly why do-it-yourself filers forget them, even though they can be worth more than every receipt combined.
1. Half of Your Self-Employment Tax
Self-employment tax is 15.3%: 12.4% for Social Security and 2.9% for Medicare. It applies to 92.35% of your net self-employment earnings, and the Social Security part stops at the 2026 wage base of $184,500.
You can deduct the employer-equivalent half of this tax on Schedule 1. Tax software usually figures it from Schedule SE, but check that it actually flowed through.
2. Self-Employed Health Insurance
Medical, dental, and qualifying long-term care premiums for you, your spouse, and your dependents are deductible on Schedule 1. The deduction can’t exceed your business’s net profit.
There’s one catch that trips people up. You can’t take it for any month you were eligible for a subsidized employer plan, including one offered through your spouse’s job.
3. Retirement Contributions
A retirement plan is the largest legal deduction most freelancers have. For 2026, the main options are:
- SEP IRA: Contribute roughly 20% of net self-employment earnings (after the half SE tax deduction), up to $72,000.
- Solo 401(k): Defer up to $24,500 as the “employee,” plus a profit-sharing contribution as the “employer,” up to $72,000 combined.
- Catch-up contributions: Solo 401(k) owners aged 50 and over can add $8,000, and those aged 60 to 63 can add $11,250 instead.
A Solo 401(k) generally has to be set up by December 31 to accept employee deferrals for that year. SEP IRAs, by contrast, can be opened and funded as late as your filing deadline, including extensions.
The QBI Deduction After the 2025 Tax Law
The Qualified Business Income deduction lets many sole proprietors deduct up to 20% of their net business profit. It was scheduled to expire after 2025. The One Big Beautiful Bill Act made it permanent.
For 2026, the full deduction is available below taxable income of $201,750 for single filers and $403,500 for joint filers. Above those amounts, limits phase in, and they hit “specified service” businesses such as consulting, law, and accounting the hardest.
Starting in 2026, the law also adds a $400 minimum deduction. It applies if you have at least $1,000 of QBI from a business you materially participate in. Your Schedule C deductions reduce QBI, so the two work together rather than competing.
- Commuting: Driving from home to a regular office or studio is personal, even with a home office elsewhere in the house.
- Everyday clothing: Work clothes count only if they’re unsuitable for street wear, such as safety gear or branded uniforms.
- Unpaid invoices: Cash-basis freelancers never reported that income, so a client who doesn’t pay creates no bad-debt deduction.
- Fines and penalties: Parking tickets and IRS penalties are not deductible, even when incurred on business.
- Your own time: You can’t pay yourself a wage from a sole proprietorship and deduct it. Owner draws are not an expense.
Records That Back Up Every Deduction
A deduction without a record is just a guess. If the IRS asks, you’ll need proof of what you paid, when, and why it was for business.
Keep receipts, invoices, bank and card statements, mileage logs, and a note of the business purpose for meals and travel. Hold onto them for at least three years after you file. A separate business bank account makes all of this far easier.
Report All Income, Even Without a 1099
Starting with payments made in 2026, clients only have to send Form 1099-NEC when they pay you $2,000 or more, up from $600. Smaller jobs may arrive with no form at all.
All of that income is still taxable. Underreporting while claiming full deductions is one of the clearest audit triggers there is. If an IRS notice ever does arrive, our guide to the IRS audit letter explains what each type means.
Pay Estimated Taxes on Time
Deductions lower your bill, but they don’t remove the duty to pay during the year. If you expect to owe $1,000 or more, the remaining 2026 estimated tax deadline is January 15, 2027. The 2027 payments then fall due on the usual April, June, September, and January schedule.

As your profit grows, an S corporation election can eventually save more than any single deduction. Our S corp tax calculator shows the break-even point. A tax accountant for small business can also confirm which method gives you the larger write-off.
Frequently Asked Questions
What is the biggest tax deduction for self-employed people?
For most freelancers, retirement contributions are the largest. A SEP IRA or Solo 401(k) can shelter up to $72,000 in 2026. The QBI deduction, worth up to 20% of business profit, is usually next.
Can I deduct expenses if I don’t have receipts?
Bank and card statements help, but they don’t show what you bought or why. For meals, travel, gifts, and vehicle use, the IRS expects written records made at or near the time. Rebuild missing records now, while you still remember the details.
Is my cell phone bill tax deductible if I’m self-employed?
Yes, the business-use share is deductible. If 60% of your calls and data are for work, you can deduct 60% of the bill. Keep a few months of usage notes to support the percentage.
What mileage rate do I use for 2026?
Use 72.5 cents per mile for business miles driven from January 1 through June 30, 2026. Miles driven from July 1 through December 31, 2026 use 76 cents per mile.
Do deductions reduce self-employment tax too?
Schedule C expenses and the home office deduction reduce both income tax and self-employment tax. Adjustments on Schedule 1, such as health insurance and retirement contributions, reduce only income tax.
