Side Hustle Taxes: Complete Guide for DoorDash, Uber, and Gig Workers

Gig Workers Are Self-Employed: Why It Matters

When you work for a gig platform like DoorDash, Uber, Lyft, Instacart, or TaskRabbit, you are classified as an independent contractor, not an employee. This means the company does not withhold taxes from your pay. No federal income tax, no Social Security, no Medicare. You receive the full payment and are responsible for reporting and paying all taxes yourself.

As an independent contractor, you are subject to both federal income tax and self-employment tax. The self-employment tax is 15.3% (12.4% for Social Security plus 2.9% for Medicare) and covers both the employee and employer portions of FICA taxes. This is on top of your regular income tax. Calculate your full obligation using our self-employment tax calculator.

You will receive a Form 1099-NEC from each platform that paid you $600 or more during the year. However, you must report all gig income even if you earned less than $600 from a particular platform and did not receive a 1099.

The $400 Self-Employment Tax Threshold

You must file a tax return and pay self-employment tax if your net self-employment income (from all gig work combined) is $400 or more for the year. This threshold is much lower than the standard filing requirements because it applies specifically to SE tax, not income tax.

Net self-employment income means your gross gig earnings minus deductible business expenses. If you earned $5,000 from DoorDash and had $4,700 in deductible expenses, your net SE income is $300, and you would not owe SE tax. However, if your total income from all sources exceeds the standard deduction, you still need to file a return and report the gig income.

Important: the $400 threshold applies to net SE income, not gross receipts. This is why tracking expenses carefully can make a real difference in your tax obligation.

Schedule C: Reporting Your Gig Income and Expenses

As a self-employed gig worker, you report your business income and expenses on Schedule C (Profit or Loss from Business), which is attached to your Form 1040. The key sections include:

• Part I - Income: Report all gross receipts from gig work. If you drive for multiple platforms, combine the totals.
• Part II - Expenses: Deduct all ordinary and necessary business expenses such as mileage, phone costs, supplies, and insurance.
• Net profit or loss: Your gross income minus expenses flows to your Form 1040 and Schedule SE.

You need a separate Schedule C for each distinct business activity. If you drive for Uber and also do freelance web development, these are two separate businesses requiring two Schedule C forms. However, if you drive for both DoorDash and Uber (same type of activity), you can combine them on one Schedule C.

The Mileage Deduction: Your Biggest Tax Saver

For delivery and rideshare drivers, the mileage deduction is typically the largest single deduction. The IRS offers two methods for deducting vehicle expenses:

Standard mileage rate (2026): 70 cents per mile. This is the simplest method. Track every mile you drive for business and multiply by the IRS rate. Business miles include driving to pick up a passenger or delivery, driving to the drop-off, and driving between gigs. Your commute from home to your first gig and from your last gig to home is not deductible unless your home qualifies as your principal place of business.

Actual expense method. Track all vehicle costs: gas, insurance, maintenance, repairs, depreciation, registration, and car washes. Deduct the business-use percentage. If you drive 20,000 miles total and 12,000 are for gig work, 60% of your actual vehicle costs are deductible.

Use a mileage tracking app from day one. The IRS requires contemporaneous records, meaning you need to track miles as you drive, not reconstruct them later. Popular free apps include Stride, Everlance, and MileIQ.

Other Deductible Expenses for Gig Workers

Beyond mileage, gig workers can deduct numerous business expenses. The key test is that the expense must be ordinary (common in your type of work) and necessary (helpful for your business):

• Phone and data plan: The business-use percentage of your cell phone bill. If you use your phone 60% for gig work, 60% is deductible.
• Hot bags and delivery equipment: Insulated bags, phone mounts, chargers, and other equipment purchased for deliveries.
• Tolls and parking: Business-related tolls and parking fees are deductible in addition to the mileage deduction.
• Platform fees and commissions: Fees deducted by the platform from your earnings (though these are often already reflected in your 1099).
• Health insurance premiums: If you are not eligible for employer coverage, you can deduct self-employed health insurance premiums above the line.
• Roadside assistance and car insurance: The business-use percentage of your auto insurance and roadside plans like AAA.

Quarterly Estimated Tax Payments

Since no taxes are withheld from gig payments, you must make quarterly estimated tax payments if you expect to owe $1,000 or more for the year. The deadlines are April 15, June 15, September 15, and January 15 of the following year. Failure to make these payments results in an underpayment penalty.

A practical approach for gig workers: set aside 25-30% of every gig payment in a separate savings account. When a quarterly deadline arrives, pay the accumulated amount. This ensures you always have enough to cover your tax obligation without scrambling.

If you also have a W-2 job, there is an easier alternative. Submit a new Form W-4 to your employer and increase your withholding to cover the tax on your gig income. This way, all your taxes are handled through payroll withholding and you avoid the quarterly payment process entirely. Use our income tax calculator to estimate your combined tax from all sources.

Side Hustle Plus W-2 Job: How It Works Together

Many gig workers have a primary W-2 job and do gig work on the side. All your income is combined on your tax return. Your W-2 wages and gig income together determine your tax bracket. This means your gig income is effectively taxed at your highest marginal rate since it sits "on top" of your W-2 income.

For example, if your W-2 job pays $60,000 and you earn $20,000 from DoorDash after expenses, your total income is $80,000. The DoorDash income is taxed in the 22% bracket (for a single filer), plus the 15.3% self-employment tax on the gig portion. Your effective tax rate across all income will be lower, but the marginal rate on your gig earnings is significant.

One advantage of this scenario: your W-2 job already covers much of the standard deduction. This means every dollar of gig deduction directly reduces your taxable income, making expense tracking especially valuable.

Common Mistakes Gig Workers Make

Not tracking miles from the start. The mileage deduction is often worth thousands of dollars, but without contemporaneous records, you cannot claim it. Start tracking on your very first gig drive.

Forgetting self-employment tax. Many gig workers only plan for income tax and are shocked when they discover the additional 15.3% SE tax. Always calculate both components when estimating your obligation.

Not saving for taxes throughout the year. Receiving the full payment without withholding feels great until tax time. Setting aside money immediately is essential, not optional.

Missing deductions. Every dollar of unclaimed deduction is roughly 30-37 cents in extra tax paid. Keep receipts, use expense tracking apps, and review all potential deductions before filing.
