So you've joined the gig economy. Maybe you're driving for rideshare apps, freelancing on the side, or running your own small business. Congrats! You're your own boss now. But here's the not-so-fun part: you're also your own payroll department, accountant, and tax preparer.
And if you're like most 1099 workers we see at Brick Taxes, you're probably making at least a few costly mistakes without even realizing it.
The good news? Every single one of these mistakes is fixable. Let's break down the seven most common 1099 tax errors and, more importantly, how to avoid them so you can keep more of your hard-earned money where it belongs, in your pocket.
Mistake #1: Not Tracking Expenses Throughout the Year
Here's a scenario we see all the time: it's April, tax season is in full swing, and someone comes to us with a shoebox full of receipts (or worse, no receipts at all) trying to piece together their business expenses from the past year.
Sound familiar?
When you're self-employed, your expenses are your best friend at tax time. They directly reduce your taxable income. But if you're not tracking them consistently, you're either:
- Missing deductions you're entitled to
- Scrambling to reconstruct records (and probably missing things)
- Stressing yourself out way more than necessary
The Fix: Set up a simple tracking system now. It doesn't have to be fancy. A spreadsheet works. So does an app like QuickBooks Self-Employed or even just a dedicated folder in your email for digital receipts. The key is consistency, log expenses weekly, not yearly.

Mistake #2: Ignoring Quarterly Estimated Taxes
This one catches a lot of first-time gig workers off guard. When you're a W-2 employee, taxes get pulled from your paycheck automatically. But when you're a 1099 contractor? Nobody's withholding anything. That's on you.
The IRS expects you to pay taxes four times a year through estimated tax payments. Miss those payments, and you'll face penalties and interest on top of your tax bill. We've seen people owe thousands extra just in penalties alone.
The Fix: Mark these quarterly deadlines on your calendar right now:
- April 15
- June 15
- September 15
- January 15 (of the following year)
A good rule of thumb is to set aside 25-30% of every payment you receive. Open a separate savings account just for taxes so you're not tempted to spend it.
Mistake #3: Confusing 1099-NEC and 1099-K
If you're doing gig work, you might receive both a 1099-NEC and a 1099-K. And yes, they're different.
1099-NEC (Non-Employee Compensation): This is what clients send you when they've paid you $600 or more for services during the year. Think freelance work, consulting, or contract jobs.
1099-K (Payment Card and Third-Party Network Transactions): This comes from payment platforms like PayPal, Venmo, Stripe, or Square when you've received over $600 in payments through their platform.
The confusion happens when people assume these forms are interchangeable or that receiving one means they don't need to report income from the other.
The Fix: Track ALL your income, regardless of what forms you receive. Even if you don't get a 1099 for something, you're still required to report that income. Keep your own records so nothing falls through the cracks.

Mistake #4: Assuming Payment Apps Handle Your Taxes
This is a big one. Many gig workers assume that because they're getting paid through PayPal, Venmo, or Cash App, the platform is somehow handling the tax reporting for them.
Spoiler alert: They're not.
Payment platforms may send you (and the IRS) a 1099-K if you meet certain thresholds, but they don't:
- Calculate your deductions
- Make estimated payments on your behalf
- Track your business expenses
- File your tax return
All of that is still 100% your responsibility.
The Fix: Treat payment apps as what they are, just a way to receive money. You still need to track that income, categorize it, and report it properly. If you use multiple platforms (say, Venmo for some clients and Zelle for others), make sure you're consolidating all that income when calculating your taxes.
Mistake #5: Missing Deductions You're Entitled To
Here's where a lot of gig workers leave money on the table. When you're self-employed, you can deduct legitimate business expenses from your income. But many people either don't know what qualifies or are too nervous to claim deductions they're actually entitled to.
Common deductions gig workers miss include:
- Home office expenses (if you have a dedicated workspace)
- Mileage (at 67 cents per mile for 2024 and 70 cents for 2025)
- Phone and internet (the business-use portion)
- Software and subscriptions (accounting apps, design tools, etc.)
- Professional development (courses, certifications, conferences)
- Health insurance premiums (if you're self-employed and paying your own)
The Fix: Keep detailed records of all your business-related expenses throughout the year. When in doubt about whether something qualifies, ask a tax professional. That's literally what we're here for.

Mistake #6: Not Separating Business and Personal Finances
Mixing your business and personal finances is like trying to separate salt from pepper after you've already combined them. Technically possible, but why make your life harder?
When everything runs through one bank account, you end up spending hours trying to figure out which transactions were business-related and which were personal. It's a nightmare during tax season, and it increases your chances of making errors.
The Fix: Open a separate bank account for your business income and expenses. It doesn't have to be a fancy business account: even a separate personal checking account works. Just keep it dedicated to business transactions only. Your future self (and your tax preparer) will thank you.
Mistake #7: Trying to DIY Complex Tax Situations
Look, we get it. There's a certain pride in handling things yourself. And for simple W-2 situations, DIY tax software can work just fine.
But 1099 taxes? They're a different animal. Between self-employment tax, estimated payments, deduction optimization, and potential audit triggers, there's a lot that can go wrong. One mistake can cost you hundreds or even thousands of dollars.
The Fix: Work with a tax professional who understands gig worker and self-employment taxes. At Brick Taxes, our Enrolled Agent (EA) is federally licensed to represent taxpayers before the IRS, which means we don't just prepare your return: we can help if questions come up later.
We offer both remote and in-person appointments, and we use TaxDome to make document sharing and communication seamless. No more faxing or scanning a million pages.

The Bottom Line
Being a 1099 worker comes with freedom and flexibility, but it also comes with responsibility. The tax code wasn't designed with gig workers in mind, so it's up to you to stay organized, track your income and expenses, and make those quarterly payments.
The seven mistakes we covered today are incredibly common: but they're also completely avoidable. Start with small changes: set up an expense tracker, open that separate bank account, and mark those estimated tax deadlines.
And if you're feeling overwhelmed or just want to make sure you're doing everything right, that's what we're here for.
