What Expenses Can a 1099 Contractor Deduct? A Complete Schedule C Breakdown
A line-by-line guide to every deduction a 1099 contractor or freelancer can claim on Schedule C. Includes 2025/2026 figures, IRS rules, and common pitfalls.
If you got a 1099-NEC this year, or you run a single-member LLC, or you freelance, or you drive for a delivery app, every dollar of legitimate business expense you don't claim is a dollar you're handing the IRS for no reason.
The catch: most freelancers either (a) miss deductions because they don't know what's allowed, or (b) over-claim things that get flagged in an audit. This guide walks through every line of Schedule C (Form 1040), what actually counts under each one, and the rules that trip people up most often. Figures below reflect the 2025 tax year (the return you filed in early 2026) and the 2026 tax year (the year you're tracking expenses for right now).
The one rule that governs every deduction
Before any specific category, the IRS standard is simple and constant: an expense must be ordinary and necessary for your trade or business.
- Ordinary means it's common and accepted in your line of work. A graphic designer buying Adobe Creative Cloud is ordinary. A graphic designer buying a jet ski is not.
- Necessary means it's helpful and appropriate — not strictly indispensable, but defensible if asked.
If an expense fails either test, it doesn't matter what category it falls under. If it passes both, the only remaining question is which line it goes on.
Who files Schedule C?
You file Schedule C if any of the following apply:
- You receive 1099-NEC or 1099-K income as an independent contractor
- You're a sole proprietor (no formal entity, just doing business in your own name)
- You're a single-member LLC that hasn't elected S-corp or C-corp taxation
- You earn side-gig income above $400 in a year (the SE-tax filing threshold)
Multi-member LLCs file Form 1065. S-corps file 1120-S. Both have different deduction mechanics — most of what's below still applies in spirit, but the form is different.
The Schedule C deduction lines, explained
Schedule C, Part II runs from Line 8 through Line 27. Here's what each line means in real freelancer terms.
Line
Line 8Advertising
Anything you spend to get customers in front of your business: Google Ads, Meta/Instagram ads, LinkedIn promotion, sponsored posts, business cards, branded swag, sponsored newsletter placements, SEO tools, your website hosting and domain, logo design, photography for marketing.
What's not advertising: client gifts (Line 27a, Other, capped at $25/person/year) and entertainment (no longer deductible at all since the Tax Cuts and Jobs Act).
Line
Line 9Car and Truck Expenses
This one has two methods, and once you pick the standard mileage method for a vehicle in its first business-use year, you can switch to actual expenses later. If you start with actual expenses, you're locked in.
2025
70¢ per business mile
2026
72.5¢ per business mile
Actual expense method: track gas, insurance, repairs, registration, depreciation, lease payments, etc., then deduct the business-use percentage.
For most freelancers, especially rideshare drivers, real estate agents, and anyone with a high-mileage low-cost vehicle, standard mileage wins. Use a mileage app (MileIQ, Stride, Everlance) and log every business trip with date, destination, and purpose. The IRS wants contemporaneous records, not a spreadsheet you reconstruct in April.
Commuting between your home and a regular workplace is never deductible. Travel between job sites, to client meetings, or to a business errand is.
Line
Line 10Commissions and Fees
Referral fees, affiliate payouts, sales commissions to non-employees. Freelancers rarely use this line.
Line
Line 11Contract Labor
Money you paid to other 1099 contractors. Subcontracted designers, freelance editors, virtual assistants — anyone who isn't your employee but did paid work for your business.
If you paid any single contractor $600 or more during the year, you're required to issue them a 1099-NEC. Skipping this is the #1 audit-trigger I see for new freelancers.
Line
Line 12Depletion
Almost no freelancer touches this. It's for natural-resource extraction (timber, oil, gas).
Line
Line 13Depreciation and Section 179
When you buy equipment with a useful life over one year — a laptop, camera body, ergonomic chair, video gear — you generally depreciate it over its useful life. Section 179 lets you expense most of it in the year of purchase, up to a generous limit ($1.16M+ for recent years). Bonus depreciation rules have been changing year to year under recent legislation; check the current percentage when you file.
For a freelancer's typical $2,000 laptop, Section 179 means you deduct the full $2,000 the year you buy it. Keep the receipt.
Line
Line 14Employee Benefit Programs
Only relevant if you have W-2 employees. Skip if you're a solo operator.
Line
Line 15Insurance (other than health)
Business liability insurance, errors and omissions (E&O), professional malpractice insurance, cyber-liability, business property insurance, business auto insurance (if not using standard mileage).
Health insurance does not go here. Self-employed health insurance has its own deduction on Schedule 1 — see "The deductions that aren't on Schedule C" below.
Line
Line 16Interest
Interest on business loans, business credit cards, and the business-use portion of mixed-use credit cards. The cleanest path is a dedicated business credit card so you don't have to allocate.
Interest on a personal credit card you sometimes use for business? Deductible only on the business portion, and you'd better have records.
Line
Line 17Legal and Professional Services
CPA fees, bookkeeper fees, tax prep (the portion attributable to your business), business attorney fees, contract review, trademark filings, business consulting. Notably, this is also where tax software — the business portion — typically goes.
Line
Line 18Office Expense
The everyday stuff: pens, paper, printer ink, postage, shipping supplies, small office decor. Different from "Supplies" (Line 22) in practice mainly by IRS convention; either is defensible for typical office consumables.
Line
Line 19Pension and Profit-Sharing Plans
For W-2 employees' retirement contributions. Your own retirement contributions (SEP-IRA, Solo 401(k), SIMPLE IRA) go above-the-line on Schedule 1 — not here.
Line
Line 20Rent or Lease
- 20a: Rent on vehicles, machinery, equipment (e.g., leased camera gear, leased work truck).
- 20b: Rent on business property — coworking memberships (WeWork, Industrious), studio space, dedicated office rent.
Your home rent does not go here. That flows through the home office deduction (covered below).
Line
Line 21Repairs and Maintenance
Fixing or maintaining business property. Repairing your work laptop, servicing leased equipment, maintenance on a business vehicle (if using actual-expense method). Capital improvements (replacing a roof) get depreciated, not expensed.
Line
Line 22Supplies
Materials consumed in the course of doing the work itself. A photographer's memory cards. A potter's clay. A contractor's nails. The line between "Supplies" (Line 22) and "Office Expense" (Line 18) is fuzzy and rarely matters — pick a convention and be consistent.
Line
Line 23Taxes and Licenses
Business licenses, professional licenses (bar dues, real estate license, contractor's license), state and local business taxes, sales tax you remit (if not netted against revenue), payroll taxes you pay on employees' wages, vehicle registration (business portion).
Not deductible here: federal income tax, self-employment tax (the SE-tax deduction is taken separately, on Schedule 1).
Line
Line 24Travel and Meals
Two sub-lines, two different rules:
- 24a — Travel: 100% deductible. Airfare, hotels, rental cars, baggage fees, business-trip Uber rides, conference fees. Trip must be primarily for business.
- 24b — Meals: 50% deductible. Meals while traveling for business, meals with clients where business is discussed, food at a working dinner. The pandemic-era 100% restaurant-meal deduction expired at the end of 2022 — we're back to 50%.
Entertainment (sports tickets, concerts, golf rounds with clients) is 0% deductible — gone since the 2017 tax overhaul. Don't try.
Line
Line 25Utilities
Business phone line, dedicated business internet, business cell plan. If your phone or internet is mixed-use, you allocate by business-use percentage and deduct that share. A second line dedicated 100% to business is cleaner from a recordkeeping standpoint.
If you claim a home office, the utility share for that portion of your home goes through the home office deduction, not here.
Line
Line 26Wages
W-2 wages paid to employees. Skip if you have no employees.
Line
Line 27aOther Expenses
The catch-all. Attach a statement listing each "Other" expense and what it is. Common entries:
- Software subscriptions — Adobe, Figma, Notion, Zoom, ChatGPT Plus, Claude Pro, GitHub, hosting, password managers
- Bank and merchant fees — Stripe, PayPal, Square processing fees, business bank account fees
- Continuing education — courses, books, professional certifications related to your existing line of work
- Dues and subscriptions — professional associations, trade publications
- Client gifts — capped at $25 per recipient per year
The audit risk on Line 27a is moderate-high simply because it's where everything weird lands. Be specific in your descriptions.
The deductions that aren't on Schedule C (but matter most)
These come off your income on Schedule 1 (Part II — Adjustments to Income). While they don't reduce your self-employment tax like Schedule C deductions do, they reduce your AGI for income tax purposes and are highly valuable.
Self-employment tax deduction
You pay 15.3% SE tax on your net business income (Social Security + Medicare, both halves). The IRS lets you deduct half of that as an adjustment to income. TurboTax, FreeTaxUSA, and any decent tax software calculate this automatically — you don't need to do anything special, but know it exists.
Self-employed health insurance deduction
If you pay for your own health insurance (not eligible through a spouse's employer plan), you can deduct 100% of the premiums for yourself, your spouse, and dependents — up to your net SE income. This is one of the largest single deductions most freelancers have. Don't bury it inside Line 15.
Retirement contributions
Solo 401(k) and SEP-IRA contributions for yourself are deducted here, not on Schedule C. A SEP-IRA lets you contribute up to roughly 20% of net SE earnings (effective rate after the SE-tax deduction wash). A Solo 401(k) can let you contribute even more if your income is moderate. Both reduce taxable income directly.
Qualified Business Income (QBI) deduction — Section 199A
Up to a 20% deduction on qualified business income, taken on Form 8995 or 8995-A. Subject to income thresholds and "specified service trade or business" rules (lawyers, accountants, consultants, financial advisors, performers, and "any trade where the principal asset is the reputation or skill of the owner" face phase-outs at higher income levels). For most freelancers under the threshold, it's a free 20% off the top of business profit.
The home office deduction — its own beast
Two methods. Pick whichever gives you more.
Simplified method: $5 per square foot of dedicated business-use space, capped at 300 square feet ($1,500 max).
Regular method (Form 8829): Calculate the business-use percentage of your home (square footage of office ÷ total square footage). Deduct that percentage of:
- Rent or mortgage interest
- Property taxes
- Utilities
- Homeowner's/renter's insurance
- Home repairs and maintenance
- Depreciation (if you own)
Two non-negotiable requirements:
- Regular and exclusive use. The space must be used only for business. The kitchen table you also eat dinner at doesn't qualify.
- Principal place of business. This is your main place of business, or it's where you regularly meet clients, or it's a separate structure used for business.
W-2 employees can no longer claim this since 2017. Self-employed taxpayers absolutely still can.
Common deductions freelancers miss
- Bank fees and payment processor fees — Stripe and PayPal alone often add up to four figures a year for active freelancers
- Cell phone business-use percentage
- Health insurance premiums (people forget this is a separate above-the-line deduction)
- Professional development — courses and conferences related to your existing skills
- Software subscriptions scattered across personal credit cards
- Mileage for client meetings, supply runs, post office trips
- Quarterly estimated tax payment processing fees
- Square footage of a true home office — many people skip it out of audit fear, but if you actually qualify, claim it
Common mistakes that get audited
Eight patterns that flag returns. Avoid all of them and your audit risk drops to roughly zero.
- 01
Mixing personal and business cards. Get a dedicated business checking account and credit card on day one.
- 02
Round-number expenses. "$1,000 supplies" on a flat round figure looks made up. The IRS notices.
- 03
Claiming 100% business use on a vehicle you're driving to the grocery store.
- 04
Deducting clothing. Generally not deductible unless it's a uniform or PPE that can't be worn day-to-day. Your "client meeting outfit" doesn't count.
- 05
Deducting gym memberships, haircuts, dry cleaning. Almost never deductible.
- 06
Home office that's actually the corner of the living room. Fails the "exclusive use" test.
- 07
Not issuing 1099s to subcontractors you paid $600 or more.
- 08
Over-claiming meals. Coffee alone with no client doesn't make it a business meal.
What records does the IRS actually want?
For every deduction, you should be able to produce:
- The amount
- The date
- The business purpose
- The vendor or recipient
- A receipt or bank/card statement entry
For meals and travel, the business purpose and (for meals) the people present are required. For mileage, contemporaneous logs beat reconstructed ones every time.
The IRS generally has three years to audit a return (six if substantial under-reporting is found). Keep records for at least seven years to be safe.
How Smart Deductions fits in
The hardest part of all this isn't knowing the rules — it's actually sorting through twelve months of bank and credit card transactions and assigning each one to the right Schedule C line. That's the part that takes a CPA five hours and costs you $750, or takes you a Saturday and a lot of caffeine.
Smart Deductions 1099 expense tracker is a free, browser-based tool that does this part automatically:
- Upload a bank statement PDF or CSV — it parses locally in your browser, nothing is uploaded to any server
- Each transaction gets auto-tagged to a Schedule C line based on merchant name and category rules
- You review and correct anything the classifier got wrong (it's typically right 85–95% of the time on freelancer spending)
- Export an IRS-ready CSV summary plus a full transaction ledger you can hand to your CPA or paste into TurboTax
No account, no payment, no data leaving your machine. It exists because doing this in a spreadsheet is miserable and most "expense tracker" apps want a $15/month subscription and your bank login.
Quick FAQ

+When are quarterly estimated taxes due?
The bottom line
Schedule C is twenty lines of opportunity that most freelancers under-use because the categories sound bureaucratic. The reality is most of your business spending probably falls into five or six lines: software (27a), meals (24b), mileage (9), home office (Line 30), professional services (17), and the catch-all stuff on 27a.
Track it as you go. Categorize once a quarter, not once a year. Keep your business and personal finances separate from day one. And remember the rule that overrides every line: ordinary and necessary, with records to back it up.
If you'd rather not do the categorization by hand, the Smart Deductions 1099 expense tracker will sort a year of transactions in about ninety seconds — for free, in your browser, with nothing leaving your device.
