Quick-scan 1099 deductions list (2026)
| Deduction | Claimed on | Cuts SE tax? | Keep / eligibility |
|---|---|---|---|
| QBI deduction (20%) | Form 8995 / 1040 | No | Most filers below 2026 taxable-income thresholds; §199A limits apply above |
| Business mileage (72.5¢/mi) | Schedule C | Yes | Contemporaneous mileage log |
| Home office | Schedule C (Form 8829) | Yes | Regular & exclusive business use |
| SE health insurance | Schedule 1 | No | Premium statements; no employer plan |
| Solo 401(k) / SEP-IRA | Schedule 1 | No | Plan documents, contribution receipts |
| Half of SE tax | Schedule 1 | No | Automatic |
| Software & subscriptions | Schedule C | Yes | Invoices; business-use portion |
| Equipment (Section 179) | Schedule C (Form 4562) | Yes | Receipts; business-use % |

Only Schedule C expenses reduce business profit — and therefore both income-tax and self-employment-tax exposure — and every one must be ordinary and necessary for your business. Certain Schedule 1 adjustments (the deductible half of SE tax, qualifying self-employed health-insurance premiums, and eligible retirement contributions) can reduce AGI but do not reduce Schedule C profit or SE tax. The QBI deduction is separate again: it can reduce taxable income but does not reduce AGI, Schedule C profit, or SE tax. Personal deductions like the standard deduction never touch Schedule C profit. Keep receipts, bank statements, and logs as you go — most lost deductions die from missing records, not IRS rules. You can estimate how added expenses change your total tax in the main calculator, and remember that lower expected profit usually means smaller quarterly estimated payments on Form 1040-ES.
The ranked list (2026)
Ranked by typical dollar savings for a mid-six-figure freelancer. Numbers assume the 22% federal bracket plus 15.3% SE tax (where applicable). State tax savings come on top of these. Before you file, work through the freelancer tax season checklist to gather the records each deduction needs, or jump straight to the freelancer tax deductions checklist for a category-by-category run-through of what to claim.
QBI deduction (20% of qualified business income)
Most freelancers can claim up to a 20% deduction on qualified business income, subject to §199A rules. Wage/property and SSTB limitations begin phasing in above 2026 taxable income of $201,750 (single and most other returns) / $403,500 (MFJ); $201,775 applies to married filing separately. Federal only — does not reduce SE tax, and California does not conform either (see the California freelancer tax guide for that wrinkle). Worth $1,500–$3,000+ for a typical $80k freelancer. No paperwork beyond claiming it on Form 8995.
Business mileage (72.5¢/mi for 2026)
Every business mile driven (between job sites, to client meetings, to suppliers) qualifies. Use the mileage deduction calculator to estimate. A drive-heavy freelancer logging 15,000 business miles deducts $10,875 — that alone cuts SE tax by roughly $1,500 (92.35% × 15.3%), and it reduces federal income tax further at your marginal rate. For the standard-vs-actual choice, see can freelancers deduct car expenses.
Home office deduction
Simplified method: $5/sq ft up to 300 sq ft = max $1,500. Actual-expense method can deduct much more for large offices in high-rent homes. Reduces both federal and SE tax. See the full home office deduction guide, or the beginner question can freelancers deduct home office expenses for the rules in plain English.
Self-employed health insurance premiums
Premiums for health, dental, and long-term care insurance for you, your spouse, and dependents — fully deductible above the line on Form 1040 (Schedule 1, line 17). Doesn't reduce SE tax, but commonly worth $2,000–$8,000 in federal income tax savings. See the dedicated self-employed health insurance deduction page.
Solo 401(k) and SEP-IRA contributions
2026 Solo 401(k) limits: $24,500 employee deferral + employer side up to 25% of net SE earnings (combined cap $72,000). SEP-IRA: 25% of net SE earnings up to $72,000. Reduces income tax substantially — does not reduce SE tax. Worth $5,000–$15,000+ in federal tax savings depending on contribution size.
Half-SE deduction
After paying SE tax, half of it is automatically deductible above the line. Reduces federal income tax (not SE tax). For an $80k freelancer, that's roughly a $5,228 deduction → $1,150 in income tax saved at 22%.
Software, subscriptions, and SaaS tools
Adobe Creative Cloud, Zoom, Notion, Slack, project-management tools, accounting software, design assets — fully deductible business expenses. Most freelancers spend $500–$3,000/year. Reduces both federal and SE tax. See can freelancers deduct software expenses for a category-by-category run-through.
Equipment, computers, and depreciable assets
Computers, cameras, phones, tools — fully deductible up to the Section 179 limit ($2,560,000 for 2026, far above what any solo freelancer would spend). Qualifying items costing $2,500 or less per invoice or item can generally be expensed under the de minimis safe-harbor election rather than capitalized. Reduces both federal and SE tax.
Professional services
CPA fees, attorney fees, contractor / freelancer subcontractor payments, agency commissions. Fully deductible. Often overlooked: the cost of this year's tax prep is deductible on this year's return. For the full category walkthrough, see can freelancers deduct professional fees.
Marketing and advertising
Website hosting, domain registration, paid ads (Google, Meta, LinkedIn), business cards, branded merchandise, sponsorships. Fully deductible. Reduces both federal and SE tax. See can freelancers deduct advertising expenses for the full category walkthrough.
Continuing education and training
Courses, certifications, conferences, books, and trade publications that maintain or improve your existing business skills. Doesn't include education that qualifies you for a new profession.
Business insurance, bank fees, and processor fees
Liability insurance, professional indemnity (E&O), business bank account fees, Stripe/PayPal/Square processor fees. Often $500–$3,000/year combined. Fully deductible.
Simplified savings illustration
| Total Schedule C deductions | Approx. SE tax reduction |
|---|---|
| $5,000 | ~$706 |
| $10,000 | ~$1,413 |
| $15,000 | ~$2,119 |
| $25,000 | ~$3,532 |
Assumptions: SE-tax reduction ≈ expense × 92.35% × 15.3%, valid while net earnings stay below the $184,500 Social Security wage base (results differ near or above it). Federal income-tax savings come on top, but they depend on your marginal rate and on interactions with the half-SE and QBI deductions — treat every figure here as an approximation, not a guarantee.
Add 4–10 percentage points for state income tax savings if you live in California, New York, Oregon, or another high-tax state. Zero additional savings in Texas, Florida, or other no-tax states.
What does NOT reduce SE tax
The QBI deduction, Solo 401(k) contributions, SEP-IRA contributions, self-employed health insurance, half-SE deduction, standard deduction, and itemized deductions all reduce federal income tax only. They're still extremely valuable — just file them under "income tax savings" not "SE tax savings." For a deeper breakdown, see how to lower self-employment tax.
Deduction FAQ
What's the highest-impact deduction for most 1099 workers?
The QBI deduction (20% of qualified business income) is usually the single largest line — worth $1,500–$3,000+ for a typical $80k freelancer. Among Schedule C deductions, business mileage and home office are usually the top two by dollar impact.
Do Schedule C deductions reduce self-employment tax?
Yes — Schedule C expenses reduce both federal income tax and the 15.3% SE tax. Schedule 1 adjustments (half-SE, retirement, SE health insurance) reduce AGI but not SE tax; the separate QBI deduction reduces taxable income only.
What's the QBI deduction and who qualifies?
The Qualified Business Income deduction lets most freelancers deduct up to 20% of their qualified business income, subject to §199A rules; its limitations begin phasing in above 2026 taxable income of $201,750 (single and most other returns) / $403,500 (MFJ), with $201,775 for married filing separately. Federal only. Sole proprietors, eligible single-member LLC owners, partners, and S-corporation shareholders may qualify, subject to the §199A trade-or-business, taxable-income, wage/property, and specified-service-business rules.
Can I deduct my entire phone or internet bill?
Only the business-use portion. If 60% of your phone use is business, deduct 60% of the bill. Keep a brief record of how you arrived at the percentage in case of audit.
Do I need to itemize on my personal return to take Schedule C deductions?
No. Schedule C deductions reduce business profit before AGI. They're separate from the standard deduction (which most freelancers still take on their personal return).
