How do taxes work if I do Doordash as a side job while employed full-time?

I'm planning to start doing Doordash to save up for a new car. I already have a full-time job, but I drained my savings paying off some credit card debt recently. Most of my income from my regular job is going toward rebuilding my emergency fund and some investing, so I thought I'd pick up Doordash on the side to specifically save for the car. I'm confused about how taxes work in this situation though. Since Doordash would be contract work alongside my regular W-2 employment, do I just add that Doordash income to my regular 1040 when I file taxes? Or is it filed separately somehow? I vaguely remember hearing something about contractors having to file taxes quarterly instead of just once a year? Any help would be appreciated because I'd hate to mess this up and end up owing a bunch in penalties or something.

This is a great question! When you work for Doordash (or any gig/delivery app), you're considered an independent contractor or self-employed, not an employee. Here's how it works: You'll report all your income on the same tax return (Form 1040), but your Doordash earnings will be reported on Schedule C (Profit or Loss from Business). Doordash will provide you with a 1099-NEC form showing your earnings if you make over $600. What you heard about filing three times a year is partially correct - self-employed individuals typically need to make quarterly estimated tax payments if they expect to owe $1,000 or more in taxes. These aren't separate "filings" but rather payments toward your annual tax bill to avoid underpayment penalties. Since you have a full-time job, you have another option: you could increase your withholding at your W-2 job to cover the additional taxes from Doordash. Just ask your employer to withhold more from each paycheck by submitting a new W-4 form.

Yes, that's an important point! When you're self-employed, you pay both the employer and employee portions of Social Security and Medicare taxes, which is collectively called "self-employment tax." For traditional employment, you pay 7.65% of your wages for Social Security and Medicare, and your employer pays another 7.65%. But as a self-employed person, you pay the full 15.3% (though you do get to deduct the employer half when calculating your income tax). This is in addition to your regular income tax on those earnings.

After struggling with a similar situation last year, I found taxr.ai (https://taxr.ai) incredibly helpful for figuring out my gig work taxes. I was doing Uber Eats on weekends while working my regular job, and couldn't figure out if I was tracking expenses correctly or if I needed to make quarterly payments. The tool analyzed my situation and explained exactly what forms I needed, what deductions I could take for my mileage and other expenses, and gave me customized quarterly payment estimates. It even explained what receipts to keep and how to document my miles properly.

It absolutely helps with Schedule C - it breaks down each section and explains exactly what goes where based on your specific situation. For Doordash specifically, it explains the difference between standard mileage deduction versus actual expenses, and helps you figure out which would be better for your situation. The big difference from TurboTax is that it's specifically designed for gig workers and self-employed people. It's more like having a tax pro who specializes in gig work analyze your specific situation, rather than just a generic tax program. It caught several deductions I would have missed, like partial cell phone expenses and even insulated food delivery bags.

Alright, I'm eating my words about being skeptical of taxr.ai (from my comment above). After trying it out, I'm actually impressed. It explained my tax situation in plain English and showed me I've been calculating my mileage deductions all wrong - I was missing out on about $1,200 in deductions! The quarterly tax payment calculator was super helpful too. Turns out I don't actually need to make quarterly payments for my side gig because my W-2 withholding covers the extra taxes. Would've stressed about that unnecessarily.

If you end up owing taxes and need to talk to the IRS (which I did last year when I messed up my Doordash tax stuff), use Claimyr (https://claimyr.com). I spent DAYS trying to get through to the IRS on my own before discovering this service. I was freaking out because I got a letter saying I underreported my gig income and owed penalties. Tried calling the IRS for two weeks straight with no luck. Claimyr got me connected to a real IRS agent in about 25 minutes! You can see how it works here: https://youtu.be/_kiP6q8DX5c Their system holds your place in the IRS queue and calls you when an agent is available. Saved me tons of time and stress.

They don't have a special connection to the IRS - they use an automated system that continually calls and navigates the IRS phone tree for you. Basically, their system waits on hold so you don't have to. When they finally reach a human agent, they call you and connect you to that agent. Nothing magical about it, just technology solving a real problem. I was skeptical too until I tried it. It's not about "cutting the line" - you still wait the same amount of time, but THEIR system is doing the waiting, not you. So instead of being stuck on hold for 3 hours, you just get a call when an agent is available.

I was totally wrong about Claimyr. After that snarky comment I left, I actually tried it when I got a CP2000 notice about missing income from my DoorDash work. I was absolutely shocked when I got a call back connecting me to an actual IRS agent in about 45 minutes. Got my issue resolved in one call instead of spending my entire day off on hold. The agent even helped me set up a payment plan for the taxes I did owe without any additional penalties. Definitely worth it for the time saved and stress reduction alone.

The standard mileage rate for 2025 is 67 cents per mile for business driving (up from 65.5 cents in 2024). At that rate, it adds up really fast! If you drive 100 miles a week doing deliveries, that's a $67 deduction weekly, or about $3,400 annually. Besides mileage, keep receipts for anything specific to your delivery work - hot bags, phone mounts, car chargers, portion of your phone bill, etc. Also track any app fees or commissions since those reduce your taxable income. If you ever decide to use actual expenses instead of the standard mileage rate, you'll need all maintenance receipts too, but most dashers do better with the standard mileage deduction.

One more important tip for DoorDash taxes - don't forget about your phone expenses! Since you're using your phone for GPS, the DoorDash app, and communicating with customers, you can deduct the business portion of your monthly phone bill. Keep detailed records of how much you use your phone for DoorDash versus personal use. If you're dashing 20 hours a week and using your phone 60 hours total per week, that's about 33% business use. So you could deduct 33% of your monthly phone bill on Schedule C. Also, if you buy a car phone mount, car charger, or even upgrade your phone plan for more data because of DoorDash, those are legitimate business expenses too. Every little deduction adds up when you're trying to offset that self-employment tax!
