27 Tax Deductions Every 1099 Worker Should Know

Short answer: Self-employed tax deductions are ordinary and necessary business expenses that lower your taxable profit, from mileage and home office to software, supplies, and half of your self-employment tax. Claiming every legitimate deduction can save a 1099 worker thousands of dollars a year. The catch is proof: each deduction needs a receipt, log, or record to back it up.

You are taxed on profit, not revenue, so every dollar of deductible expense is a dollar you are not taxed on. Below are 27 deductions self-employed and 1099 workers commonly overlook, followed by how to document them properly.

What are the most common self-employed tax deductions?

To be deductible, an expense must be ordinary (common in your line of work) and necessary (helpful and appropriate for your business), per IRS rules at irs.gov. Personal costs do not qualify, and mixed-use costs are split by the business-use portion.

Here are 27 to review:

1. Business mileage — 72.5¢ per mile for 2026, or actual vehicle expenses.
2. Home office — a space used regularly and exclusively for business.
3. Phone — the business-use share of your cell plan.
4. Internet — the business-use share of home or mobile data.
5. Software and apps — tools you use to run the business.
6. Subscriptions — trade publications and professional services.
7. Office supplies — paper, ink, postage, and small items.
8. Equipment and tools — computers, cameras, and trade gear.
9. Business insurance — liability and professional coverage.
10. Health insurance premiums — for the self-employed not on an employer plan.
11. Retirement contributions — SEP-IRA, SIMPLE IRA, or Solo 401(k).
12. Half of self-employment tax — deducted from income (not SE) tax.
13. Marketing and advertising — ads, business cards, and promotions.
14. Website costs — hosting, domain, and design.
15. Professional fees — accountant, bookkeeper, and attorney.
16. Bank and payment fees — merchant, processing, and account fees.
17. Education — courses that maintain or improve your current skills.
18. Licenses and permits — required to operate legally.
19. Contract labor — payments to subcontractors (may require a 1099).
20. Business travel — airfare, lodging, and transportation away from home.
21. Business meals — generally 50% deductible with a business purpose.
22. Rent — for an office, studio, or business equipment.
23. Utilities — for a dedicated business space.
24. Repairs and maintenance — for business property and equipment.
25. Startup costs — a portion deductible in your first year.
26. Interest — on business loans and business credit cards.
27. Qualified business income (QBI) deduction — up to 20% of qualified business income for eligible filers.

Not every item applies to every business. Claim only what genuinely relates to your work.

Which deductions do 1099 workers most often miss?

A few high-value deductions get skipped because people do not track them in real time.

• Mileage. Undocumented miles are lost miles. At 72.5¢ each, even 5,000 business miles is $3,625 off your taxable profit.
• Home office. Many qualify but skip it for fear of complexity; the simplified method makes it straightforward.
• Half of SE tax. This is automatic on your return but worth understanding — it meaningfully lowers income tax.
• The QBI deduction. Eligible self-employed filers can deduct up to 20% of qualified business income, subject to income limits.

How much can deductions actually save me?

The value of a deduction depends on your combined tax rate. Because deductions reduce the income subject to both income tax and (for business expenses) self-employment tax, a business expense often saves more than its income-tax bracket alone suggests.

Business deduction claimed	Approx. combined tax saved (illustrative)
$1,000	roughly $250–$400
$5,000	roughly $1,250–$2,000
$10,000	roughly $2,500–$4,000

These figures are illustrative and depend on your bracket, filing status, and state. The point stands: deductions are real money.

What records do I need to keep for deductions?

A deduction is only as strong as its documentation. If the IRS asks and you cannot show proof, the deduction can be disallowed. Keep:

• Receipts for purchases, showing date, amount, and vendor.
• A mileage log with dates, destinations, business purpose, and miles.
• Bank and card statements that corroborate expenses.
• Invoices documenting your income.
• Home-office measurements and related bills.

The IRS generally expects you to keep records for at least three years. Reconstructing them from memory in April is where deductions get lost.

How does Keel help you prove your deductions?

The hardest part of deductions is not knowing they exist — it is having the paper trail when it counts. That is where a capture-as-you-go habit pays off.

Keel: Invoice Maker & Receipts turns your iPhone into that paper trail. Snap a receipt and the app reads it, proposes the details, and lets you approve them in seconds. It logs mileage at the 2026 IRS rate of 72.5¢ per mile and creates invoices so your income is documented too. Everything is stored encrypted on your device — no bank connection, no cloud, no account — and you export it all as one file for your accountant or tax software. Keel is not an automated bank-linked all-in-one; the honest tradeoff for that privacy is a little manual entry, which for many solo workers is a fair price for owning their data. Get Keel on the App Store.

Frequently asked questions

Can I deduct expenses without a receipt? It is risky. Some small expenses may be reconstructed from statements, but the IRS can disallow undocumented deductions. Keeping receipts and logs is the safest practice.

Can I deduct my whole cell phone bill? Only the business-use portion. If you use your phone 60% for business, you generally deduct 60% of the bill. The same split logic applies to internet and other mixed-use costs.

Is the standard mileage rate better than actual expenses? It depends. The standard rate (72.5¢ per mile for 2026) is simpler and often better for higher-mileage, fuel-efficient vehicles. Actual expenses may win for costly vehicles with lower mileage. You generally must choose in the first year the vehicle is used for business.

What is the QBI deduction? The qualified business income deduction lets eligible self-employed filers deduct up to 20% of qualified business income, subject to income thresholds and business-type rules. It is claimed on your Form 1040.

Are business meals still deductible? Business meals with a clear business purpose are generally 50% deductible. Keep the receipt and note who you met with and why.
