✅ Current for tax year 2026
Every major deduction available to freelancers and 1099 contractors this year, with current dollar limits where they matter.
If you’re self-employed, every legitimate business deduction lowers the income your tax bill is based on — both your federal income tax and your self-employment tax. Here’s the full list of deductions that actually apply to most freelancers, gig workers, and 1099 contractors in 2026, with the current numbers where they matter.
1. Half of your self-employment tax
You pay both the “employee” and “employer” halves of Social Security and Medicare tax through self-employment tax. The employer half — roughly half your total SE tax — is deductible from your income tax, even if you don’t itemize. Our 1099 & quarterly tax calculator works this out automatically, and if you’re weighing a 1099 role against a salaried one, the 1099 vs. W-2 calculator shows exactly how much this extra tax costs you.
2. Vehicle and mileage
For 2026, the IRS standard mileage rate is 72.5 cents per mile for business driving from January 1 through June 30, rising to 76 cents per mile from July 1 through December 31. You can use this flat rate instead of tracking actual gas, insurance, and depreciation costs — but you need a contemporaneous log (date, miles, business purpose) for every trip. Estimates reconstructed later don’t hold up if the IRS asks.
3. Home office
If you have a space used regularly and exclusively for business, you can deduct it two ways:
- Simplified method: $5 per square foot, up to 300 square feet (a maximum $1,500 deduction). No receipts needed, just the square footage.
- Actual expense method: the business-use percentage of your rent/mortgage interest, utilities, insurance, and repairs. More paperwork, sometimes a bigger deduction if you have a large dedicated space.
4. Health insurance premiums
If you pay for your own health insurance and aren’t eligible for a spouse’s employer plan, you can generally deduct 100% of your premiums — for yourself, your spouse, and dependents. The deduction can’t exceed your net self-employment income for the year.
5. Retirement contributions (SEP-IRA or Solo 401(k))
Contributions to a self-employed retirement plan reduce your taxable income now, on top of building retirement savings. For 2026:
- SEP-IRA: up to 25% of net compensation, capped at $72,000.
- Solo 401(k): up to $24,500 in employee deferrals (under 50), plus employer profit-sharing contributions up to 25% of compensation — with a combined cap of $72,000 (or up to $83,250 if you qualify for the age-60-63 enhanced catch-up).
A Solo 401(k) usually lets you shelter more at lower income levels because of the employee-deferral portion; a SEP-IRA is simpler to administer.
6. Business insurance
Premiums for liability insurance, professional errors-and-omissions coverage, or commercial auto insurance used for business are deductible.
7. Phone, internet, and software
The business-use percentage of your phone and internet bill counts. So does software and subscriptions you use to run the business — invoicing tools, design software, hosting, mileage-tracking apps.
8. Supplies and equipment
Everyday supplies are deductible in full the year you buy them. Larger equipment purchases can often be deducted in full in the first year under Section 179 rather than depreciated over several years, up to the annual limit.
9. Professional services
Accountant and bookkeeper fees, tax software, and legal fees related to your business are all deductible.
10. Marketing and advertising
Website costs, business cards, paid ads, and platform promotion fees.
11. Business travel and meals
Travel that’s ordinary and necessary for your business (flights, hotels, a portion of transportation) is deductible. Business meals are generally 50% deductible — the full-meal-cost rule from a few years back has not carried into 2026.
12. The Qualified Business Income (QBI) deduction
Separate from all of the above: many self-employed people can deduct up to 20% of their qualified business income on their federal return under Section 199A. It has income-based phase-outs and rules that vary by the type of work you do, so it’s worth checking whether you qualify — this deduction is not included in our 1099 & quarterly tax calculator‘s estimate, which is one reason your real tax bill is often lower than the calculator’s number.
What doesn’t count
Commuting from home to a regular workplace, clothing you could reasonably wear outside of work, and personal-use portions of anything mixed-use (a phone you use 60% personally, for example — only the 40% business use counts).
How deductions differ from credits
It’s worth being precise about terminology, because people often use “deduction” and “credit” interchangeably when they work very differently. A deduction reduces your taxable income before tax is calculated — a $1,000 deduction saves you your marginal tax rate times $1,000, not the full $1,000. A credit, by contrast, reduces your tax bill dollar for dollar after it’s calculated — a $1,000 credit saves you the full $1,000 regardless of your tax bracket. Every item on this list is a deduction, not a credit, which is why the actual savings from any one of them depends on your income level and filing status rather than being a fixed number. Two self-employed people claiming an identical $5,000 home office deduction will see different real dollar savings if they’re in different tax brackets — which is exactly what the tax deduction calculator is built to show you precisely, rather than estimate.
