If you’re an online business owner, you already know the hustle is real. You’re managing email marketing, juggling Shopify sales, scaling course launches, or growing your YouTube channel. You’re building something out of nothing and that’s impressive.
But while you’re focused on content calendars and conversion rates, one thing tends to slip down the priority list: taxes.
The world of online business comes with its own unique tax challenges. Multiple platforms. Ever-changing IRS rules. Confusing forms like the W9 and 1099 NEC. It’s easy to feel overwhelmed. And in that overwhelm, critical mistakes can happen. Mistakes that cost you money, time, and peace of mind.
At Insogna CPA, we help online entrepreneurs in eCommerce, digital content, coaching, and service-based industries stay ahead of tax mistakes and build smart financial strategies. If you’re making any of the following errors, you’re not alone but the good news is that they’re all fixable.
Let’s walk through five of the most common tax mistakes we see online entrepreneurs make and how to fix them with the right guidance from a proactive CPA in Austin, Texas.
Mistake 1: Mixing Business and Personal Finances
Why It Happens:
When you’re just starting out, separating business and personal finances doesn’t always feel urgent. One checking account seems easier to manage, and a personal card works just fine… until it doesn’t.
As your business scales, expenses add up, tax prep becomes more complicated, and the IRS starts caring a lot more about where your money is coming from and where it’s going.
What It Costs:
- Lost deductions: If a transaction is unclear, it’s often safer (and easier) for a tax preparer to skip the deduction.
- Audit risk: Commingled accounts raise red flags for the IRS.
- Legal exposure: If you’re an LLC or S Corp, mixing funds can jeopardize your liability protection.
How to Fix It:
- Step 1: Open a separate business bank account and credit card immediately.
- Step 2: Start using an accounting platform like QuickBooks Self-Employed or Xero.
- Step 3: Schedule regular reviews with a tax accountant near you to ensure clean records and clear reporting.
At Insogna CPA, we help clients not just clean up their books but set up bulletproof systems to prevent future mix-ups. This is a foundational step in building a tax-efficient, scalable business.
Mistake 2: Missing Out on S Corp Tax Savings
Why It Happens:
You’ve heard about the S Corp structure on a podcast or from a friend who “saved thousands” and it’s true. Electing S Corp status can be one of the most powerful tax strategies for online entrepreneurs earning consistent profits.
But too many people jump in without understanding the requirements or wait too long and miss the benefits.
What It Costs:
- Overpaying self-employment tax on your entire profit
- Failing to set up compliant payroll (a requirement for S Corps)
- Missing the IRS deadline to elect S Corp status (March 15 for current-year status)
How to Fix It:
- Evaluate: If you’re netting at least $50,000 annually, it’s worth running the numbers.
- Model: A small business CPA in Austin will compare your tax liability under your current structure versus S Corp.
- Plan: We’ll help you set a “reasonable salary,” file the right forms, and get payroll up and running.
At Insogna CPA, we build real projections to show your actual tax savings from S-Corp election and we help you implement it seamlessly, without disrupting operations.
Mistake 3: Not Tracking All Deductible Expenses
Why It Happens:
Running a business online involves dozens of small expenses. Canva subscriptions, Zoom upgrades, productivity apps, microphones, virtual assistants. On their own, they may not feel significant. But collectively, they can add up to thousands in missed deductions each year.
What It Costs:
- Higher taxable income = more taxes owed
- Overstated profits = misleading reports when applying for funding
- Missed strategic deductions like home office expenses, business travel, or education
Commonly Overlooked Expenses:
- Equipment used for video/audio content
- Subscriptions like ConvertKit, Kajabi, or Teachable
- Digital ads, SEO tools, and marketing platforms
- W9 contractors and 1099 NEC payments
- Part of your rent or mortgage if you work from home
How to Fix It:
- Use accounting software with receipt tracking
- Categorize expenses monthly
- Work with a tax advisor in Austin who understands online business
Our team helps ensure your chart of accounts reflects the unique cost categories of a digital business. We also create quarterly reviews so nothing slips through the cracks.
Mistake 4: Not Tracking Revenue Across Multiple Platforms
Why It Happens:
You’re collecting revenue from Shopify, Etsy, Stripe, PayPal, Gumroad and maybe a few affiliate programs too. The deposits hit your bank account, but tracking gross revenue, fees, refunds, and discounts across platforms is complex.
What It Costs:
- Underreporting income (a serious issue if your 1099-K totals don’t match your return)
- Overpaying taxes by misclassifying platform fees as income
- Inaccurate performance tracking across products, clients, or services
How to Fix It:
- Use revenue reporting tools or integrations with your accounting software
- Reconcile bank deposits with platform payouts
- Adjust for fees and refunds in real time
A CPA near you can help you set up these systems and create dashboards that show your actual revenue, net of fees, by product or platform.
At Insogna CPA, we guide you through the nuances of 1099-K, 1099 NEC, and income categorization so you’re never guessing when the IRS comes knocking.
Mistake 5: Only Thinking About Taxes in April
Why It Happens:
You’re busy. Tax planning doesn’t feel urgent until you realize in April that you could’ve saved thousands if you had just done a few things differently.
What It Costs:
- Missed deductions and credits
- No time for retroactive S Corp election or expense timing
- IRS penalties for late payments or underreporting
- Higher tax bills from avoidable missteps
How to Fix It:
Get proactive. The most tax-efficient entrepreneurs work with a CPA firm in Austin, Texas throughout the year not just during tax season.
Here’s what that looks like:
- Quarterly tax projections
- Cash flow planning around tax obligations
- Tax strategy built into your pricing, hiring, and growth plans
- **Help with estimated tax payments and FBAR filing for international business owners
At Insogna CPA, our clients have a clear tax strategy by the end of Q1 and we adjust it as income evolves, so there are no surprises when tax season arrives.
Bonus: Missing IRS Filing Deadlines for Contractors
Why It Happens:
You’re building a lean team of freelancers, contractors, and VAs. But you forget to collect a W9 form or fail to send a 1099 NEC before January 31.
What It Costs:
- Up to $280 in IRS penalties per missed form
- Loss of contractor expense deductions if no proper documentation
- Potential audit risk for worker misclassification
How to Fix It:
- Collect W9s during onboarding
- Track payments using your accounting software
- Let a chartered professional accountant or certified general accountant handle your 1099 compliance
At Insogna CPA, we manage this process end-to-end for our clients so you never miss a deadline or risk a deduction.
