Yes, Amazon Flex is considered self-employment for tax purposes. Amazon’s contractor agreement classifies drivers as independent contractors, the IRS treats the income the same way, and the practical result is that you file a Schedule C, pay both halves of Social Security and Medicare through self-employment tax, and send the IRS quarterly estimated payments throughout the year. Nothing is withheld from your Flex deposits, so every dollar Amazon pays you is gross income that you have to account for yourself.
Why the IRS Treats Flex Drivers as Self-Employed
A contract calling you an independent contractor doesn’t by itself settle the question. The IRS looks at how the working relationship actually functions, weighing behavioral control, financial control, and the nature of the relationship.1Internal Revenue Service. Independent Contractor or Employee For Flex, all three factors point the same direction.
Behavioral control is light. You choose which delivery blocks to accept and set your own schedule. Amazon provides delivery instructions and uses its app to organize routes, but it isn’t telling you which streets to take or how to walk a package to a doorstep.
Financial control sits squarely with the driver. You supply the car, pay for gas and maintenance, carry your own personal auto insurance, and absorb wear and tear. Amazon doesn’t reimburse any of that. When a worker invests their own money in the tools needed to do the job, that weighs heavily toward self-employment.
The relationship itself is block-by-block. No ongoing promise of work, no benefits, no employment agreement, just a services contract. Add that to Amazon’s own Independent Contractor Terms of Service, which state outright that Amazon will not withhold income tax, Social Security, or Medicare and will not provide health insurance, paid leave, or retirement contributions, and the classification is settled.
Reporting Your Flex Income
If Amazon pays you $600 or more during the year, you’ll receive a Form 1099-NEC showing your total earnings.2Internal Revenue Service. Instructions for Forms 1099-MISC and 1099-NEC The number that catches people out: you owe tax on all your Flex income whether or not a 1099 shows up. Net self-employment earnings of $400 or more in a year require you to file, even if no form was issued.
You report earnings and business expenses on Schedule C (Profit or Loss from Business), which attaches to your Form 1040.3Internal Revenue Service. About Schedule C (Form 1040), Profit or Loss from Business (Sole Proprietorship) Your net profit from Schedule C then feeds two separate calculations: your regular income tax and your self-employment tax.
Self-Employment Tax
Employees split Social Security and Medicare taxes with their employer. You cover both halves. The self-employment tax rate is 15.3%: 12.4% for Social Security and 2.9% for Medicare, applied to 92.35% of your net earnings.4Internal Revenue Service. Topic No. 554, Self-Employment Tax This runs on top of regular income tax, which is where new drivers tend to get surprised in April.
The Social Security portion only applies to earnings up to $184,500 in 2026.5Social Security Administration. 2026 Cost-of-Living Adjustment (COLA) Fact Sheet The Medicare portion has no cap. If your total self-employment earnings exceed $200,000 (or $250,000 if married filing jointly), an additional 0.9% Medicare tax applies to the amount above that threshold.6Internal Revenue Service. Topic No. 560, Additional Medicare Tax
One built-in offset: you deduct half of your self-employment tax when calculating your adjusted gross income. The deduction goes on Schedule 1 and reduces income subject to regular income tax, though it doesn’t reduce the self-employment tax itself.7Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes)
Quarterly Estimated Payments
Because nothing is withheld, the IRS expects you to pay as you go. Quarterly estimated tax payments cover both income tax and self-employment tax, and the due dates are:8Internal Revenue Service. When to Pay Estimated Tax – Individuals
- April 15 for income earned January through March
- June 15 for income earned April through May
- September 15 for income earned June through August
- January 15 for income earned September through December of the prior year
You calculate payments using Form 1040-ES.9Internal Revenue Service. Estimated Taxes Skipping or underpaying doesn’t just delay a bill. The IRS charges an underpayment penalty even if you end up with a refund when you file. A common starting point for new drivers is setting aside 25 to 30% of each Flex deposit for taxes, then adjusting as you track actual deductions.
Deductions That Cut the Tax Bill
Deductions are the main financial advantage of self-employment. Every legitimate business expense you claim on Schedule C lowers both your income tax and your self-employment tax. The key word is track. You need records, not memories.
Vehicle Expenses
Your car is the biggest line item. You pick one of two methods and use whichever gives the bigger deduction:10Internal Revenue Service. Topic No. 510, Business Use of Car
The standard mileage rate lets you deduct 72.5 cents for every business mile in 2026.11Internal Revenue Service. IRS Sets 2026 Business Standard Mileage Rate at 72.5 Cents per Mile The rate covers gas, depreciation, insurance, and repairs together, so all you need is a mileage log. A driver who puts 15,000 business miles on their car would deduct $10,875.
The actual expense method means adding up every vehicle cost (gas, oil, tires, repairs, insurance, registration, depreciation) and deducting the business-use percentage.12Internal Revenue Service. Publication 463, Travel, Gift, and Car Expenses If 60% of your driving is for deliveries, you deduct 60% of those costs. More record-keeping, but sometimes a bigger number, especially for older cars with heavy repair bills.
Start logging miles from day one. A tracking app running in the background is the easiest way, and the app itself is deductible.
Other Business Deductions
Beyond the vehicle, several other costs qualify:
- Cell phone: the business-use portion of your monthly bill
- Supplies and equipment: phone mounts, car chargers, insulated bags, flashlights
- Parking and tolls paid during delivery blocks
- Software and subscriptions: mileage trackers, bookkeeping apps, and similar tools
Running these purchases through a separate bank account or credit card makes tax time dramatically easier. When everything flows through one account, you don’t spend hours picking through personal transactions to find deductible charges.
Health Insurance Premiums
If you pay for your own health insurance and show net profit on Schedule C, you can deduct premiums for medical, dental, and vision coverage for yourself, your spouse, and your dependents. The deduction is claimed on Schedule 1 and reduces adjusted gross income directly, so you don’t need to itemize.13Internal Revenue Service. Instructions for Form 7206 The catch: you can’t claim it for any month you were eligible to participate in a subsidized plan through an employer, your spouse’s employer, or a parent’s employer if you’re under 27. Eligibility alone disqualifies you, even if you didn’t enroll.
Retirement Accounts That Double as Tax Shelter
Losing an employer 401(k) doesn’t mean losing tax-advantaged retirement savings. Self-employed drivers have access to accounts with generous limits that cut current-year taxable income.
A Solo 401(k) lets you contribute in two roles. As the “employee,” you can defer up to $24,500 in 2026 (higher with catch-up contributions after age 50). As the “employer,” you can add up to 25% of net self-employment earnings after deducting half your self-employment tax. The combined total can’t exceed $72,000 in 2026, before catch-ups.14Internal Revenue Service. 2026 Amounts Relating to Retirement Plans and IRAs
A SEP IRA is simpler to set up and lets you contribute up to 25% of net self-employment compensation, capped at $72,000 in 2026.15Internal Revenue Service. SEP Contribution Limits (Including Grandfathered SARSEPs) It has no employee deferral component, so at lower income levels a Solo 401(k) shelters more. A driver with $40,000 in net profit could put roughly $34,500 into a Solo 401(k), compared to around $10,000 in a SEP.
One Thing to Verify for the 2026 Tax Year
Through the 2025 tax year, self-employed sole proprietors could deduct up to 20% of their qualified business income under Section 199A.16Internal Revenue Service. Qualified Business Income Deduction For a Flex driver with $30,000 in net profit, that was worth $6,000 off taxable income.
The provision expired December 31, 2025. Congress has considered extending it, but whether it’s available on your 2026 return depends on whether renewal legislation was enacted. Check the IRS site or a tax professional before you file, because leaving the deduction off a return where it still applies is an expensive mistake.
