Many gig workers don’t stick to one platform. You might drive passengers for Uber in the morning, deliver DoorDash orders at lunch, shop Instacart batches in the afternoon, and run Amazon Flex blocks on weekends. That’s four different 1099s — but the IRS doesn’t require four separate tax returns.
Here’s how to correctly combine income from multiple gig apps, which forms to use, and what to watch out for.
The Short Answer: One Schedule C Covers It All
If all your gig work is similar — driving, delivering, shopping with your own vehicle — the IRS allows you to report all income and expenses on a single Schedule C. You don’t need one Schedule C per app.
This is because you’re operating one business (transportation and delivery services) across multiple platforms. The fact that different companies pay you doesn’t change the nature of the work in the IRS’s view.
Step by Step: How to Combine Multiple 1099s
Step 1: Gather Every 1099
Collect your 1099-K and 1099-NEC forms from every platform:
- Uber: 1099-K (passenger trips + Uber Eats)
- DoorDash: 1099-NEC
- Instacart: 1099-NEC
- Amazon Flex: 1099-NEC
- Grubhub: 1099-NEC
- Lyft: 1099-K
- Shipt: 1099-NEC
- Walmart Spark: 1099-NEC
For platform-specific details, see our individual guides: Uber | Lyft | DoorDash | Instacart | Amazon Flex | Grubhub | Shipt | Walmart Spark
For platforms that didn’t send a 1099 (you earned under the threshold), use your in-app earnings history or bank statements.
Step 2: Add Up the Gross Income
Total every 1099’s Box 1 amount plus any earnings from platforms that didn’t issue forms. This sum goes on Schedule C, Line 1.
Step 3: Total All Your Deductions
Your deductions apply to your driving work as a whole — not per platform. Combine: total business miles across all platforms × $0.70, all equipment purchases, phone bill × business-use percentage, all tolls and parking fees, mileage tracking app subscription.
Step 4: Complete One Schedule C
Line 1: Combined gross income. Line 9: Combined mileage deduction. Line 10: Platform fees and commissions. Line 22: Supplies. Line 25: Phone. Line 31: Net profit across all platforms.
Step 5: Complete Schedule SE
Net profit × 92.35% × 15.3% = self-employment tax due.
When You Might Want Separate Schedule Cs
While one Schedule C is the standard approach for similar driving work, there are rare cases where separate forms make sense: you run two genuinely different businesses (rideshare driving AND freelance graphic design), you want to track profitability per platform, or one platform involves a different vehicle.
For the vast majority of multi-app drivers, a single Schedule C is simpler, faster, and produces the same tax result.
Important: Don’t Double-Count Income
Some drivers receive both a 1099-K from one platform and a 1099-NEC from another — and worry about being taxed twice. This doesn’t happen. Each form reports different income from different payers. Just add them all together on Line 1.
What About Quarterly Taxes?
Combined income from multiple platforms can push you over the $1,000 quarterly tax threshold faster than a single app. Even if you only make $300/month on each of four platforms, that’s $14,400/year — well into quarterly payment territory.
Track your total gig income across all platforms each month. If your annualized net profit suggests you’ll owe $1,000+, start making quarterly payments. Use our Quarterly Tax Calculator for a combined estimate.
Record-Keeping Tips for Multi-App Drivers
- Track mileage with the same app regardless of which platform you’re using — your odometer doesn’t know the difference
- Use one bank account for all gig income so you can see your total at a glance
- Keep a simple spreadsheet: each row is a week, columns show income per platform plus total
- Save your annual summaries from each app even if no 1099 was issued
