As a trusted Austin, Texas CPA firm, we help smart business owners like you transform tax season from a dreaded chore into your next big win.
In this blog, we’ll walk through the seven most costly tax mistakes small business owners make and exactly how to avoid them. We’ll also explore advanced strategies that can save you thousands and reinforce your path to financial success.
1. Mixing Personal and Business Expenses
Why This Is a Major Red Flag
The IRS expects you to maintain strict separation between your business and personal finances. Commingling funds not only complicates your accounting. It can lead to lost deductions, increased audit risk, and even disallowed expenses. Most importantly, a muddled financial picture makes it much harder to run your business efficiently.
Real-World Examples
- Charging personal items like groceries or family meals to your business account.
- Paying for your child’s tuition or a family vacation with business credit.
- Reimbursing personal expenses from your business bank account without proper documentation.
A Better Approach
- Open a dedicated business checking account and credit card.
- Use professional accounting software like QuickBooks, Xero, or FreshBooks to track expense categories accurately.
- Pay yourself a consistent salary or distribute profit, rather than transferring funds informally and later trying to sort it out.
How We Help
Our team of licensed CPAs, chartered professional accountants, and tax professionals near you ensure your books are pristine. We’ll categorize each transaction correctly, reconcile your accounts monthly, and keep you audit-ready. Saving you time, money, and stress.
2. Filing the Wrong Business Entity Tax Forms
Why the Wrong Forms Cost You
Each business structure (sole proprietorship, LLC, S Corporation, partnership) has distinct filing requirements and tax advantages. Getting this wrong means paying too much, missing out on deductions, or worse: drawing IRS scrutiny for incorrect filings.
Common Pitfalls
- Filing as a sole proprietor when an LLC with an S Corp election could save you sizable self-employment tax.
- Missing the IRS deadline for S Corp election (Form 2553), forfeiting a full year of savings.
- Using the wrong form for your entity type like filing a 1065 partnership return when an S Corp structure is more suitable.
What to Consider
- Evaluate whether your current structure suits your revenue and growth plan.
- Think of filing deadlines, pass-through income, liability protection, and administrative complexity.
- Revisit your structure annually or when your revenue significantly increases.
How Insogna Adds Value
We conduct a full entity analysis to determine whether you’re best suited as a sole prop, LLC, S Corp, or partnership. We compare tax savings, filing requirements, and liability protection. Then we help file the right forms from Schedule C and Form 1065 to Form 1120-S or Form 2553 on time and accurately.
3. Forgetting to Make Estimated Tax Payments
The Cost of Waiting
If you’re self-employed, own rental properties, or earn from 1099s, the IRS requires quarterly estimated payments. Missing them Marches in penalties and interest, and it’s easy to fall behind.
Important Due Dates
- April 15 – Q1 (previous year’s post-Jan 1–March 31)
- June 15 – Q2 (April 1–May 31)
- September 15 – Q3 (June 1–August 31)
- January 15 – Q4 (September 1–December 31, for prior year)
Easy Fixes
- Aim to set aside at least 25–30% of your net income each quarter.
- Use IRS Form 1040-ES or automated tax tools to calculate and file estimated payments ahead of deadlines.
- Plan for both regular tax and self-employment tax burdens.
How We Support You
As a full-service tax preparation firm and small business CPA in Austin, we forecast your taxes, estimate available deductions, and calculate quarterly installments so you never overpay or get hit with penalties. We’ll also automate your payments so you can focus on business growth.
4. Ignoring Payroll Tax Obligations
Payroll Isn’t Just for Companies with Multiple Employees
Even if it’s just you paying yourself as an S Corp owner, payroll taxes are mandatory. This includes Social Security, Medicare, federal withholding, and any applicable Texas requirements.
What You Must Do
- Withhold and remit taxes via IRS Form 941 each quarter.
- Prepare a Form W-2 for yourself and any employees at year-end.
- Track Texas-specific requirements, like unemployment insurance.
Penalties for Neglect
- Missing payroll tax deposits can lead to penalties up to 10% of the due amount.
- Inconsistent or late filings raise red flags with the IRS and state agencies.
How We Help
We help you select and integrate payroll solutions, track deposits precisely, and keep you fully compliant. From Form 941, payroll taxes, to annual W-2 preparation, we handle it all. Ensuring your payroll processes are smooth, compliant, and stress-free.
5. Not Tracking Deductions Properly
Deductions Mean Dollars Back in Your Pocket
Every missed deduction means you’re letting hard-earned money slip through your fingers. You’d be surprised how many small business owners overlook legitimate deductions that could significantly reduce their taxable income.
Frequently Overlooked Deductions
- Home office expenses: rent, utilities, internet—if you qualify.
- Software and subscriptions: QuickBooks, Adobe, Slack, or cloud storage services.
- Marketing and advertising costs: website hosting, social media ads, business cards.
- Business meals/business travel: plane tickets, hotels, mileage, meals.
- Professional services: CPAs, attorneys, consultants.
How to Maximize Them
- Keep a digital copy of receipts for every business expense.
- Use software to track mileage, meals, and time specifically.
- Consult with a tax accountant near you or tax advisor Austin to ensure no deduction is overlooked or misapplied.
How Insogna Supports You
We build systems that capture all deductions throughout the year and categorize them properly. Our tax professionals review expense data to ensure full IRS compliance and optimization, boosting your return and minimizing audit risk.
6. Failing to Reinstate an Inactive LLC
Don’t Let Your Liability Protection Lapse
An inactive Texas LLC that hasn’t filed the required franchise tax report or lost its registered agent support is at risk. Once forfeited, your business loses liability protection, and any contracts or bank accounts tied to it may be compromised.
Restoration Checklist
- Check your status with the Texas Comptroller.
- File any delinquent franchise tax reports.
- Provide required annual updates (registered agent, office addresses).
- Promptly reinstate if the LLC has lapsed.
How We Can Help
We monitor your LLC’s status, submit timely reports, and handle reinstatement processes. We keep your business legally protected and your relationships intact.
7. Waiting Until Tax Season to Plan Ahead
Last-Minute Planning = Lost Opportunities
Many valuable tax moves like retirement contributions, asset purchases, or charitable giving must occur before year-end. Waiting until April is too late.
Year-End Moves to Prioritize
- Retirement contributions (Solo 401(k), SEP IRA)
- Section 179 or bonus depreciation purchases
- Prepaying interest, insurance, rent, or subscriptions
- Reviewing entity structure for next year’s growth
- Checking for foreign account thresholds and FBAR filing requirements
How We Keep You Prepared
Insogna offers year-round tax strategy reviews. We help you time purchases, maximize deductions, and minimize liabilities while working alongside your long-term business goals.
Advanced Moves for Growth-Oriented Businesses
A. Capital Gains & Income Timing
Selling business assets, investing in stocks or crypto? Coordinating business income and capital gains can save hundreds or thousands of dollars through smart timing.
- Short-term gains (held <1 year) taxed at ordinary rates
- Long-term gains (held >1 year) enjoy reduced rates (0–20%)
- Harvesting capital losses can offset gains, reducing taxable income
B. FBAR & Foreign Compliance
If you hold more than $10,000 in combined foreign accounts including crypto wallets, business bank accounts, or investments, you must file the FinCEN Form 114 (FBAR) every April 15 and June 30. Non-compliance can result in cut-throat penalties.
C. Retirement Accounts + Tax Shelters
Leveraging tax-advantaged accounts remains a productive way to defer or reduce tax:
- Solo 401(k): Contributions up to $66,000 annually
- SEP IRA: Up to 25% of net business income deductible
- Health Savings Account (HSA): Triple tax advantage: deductible, grows tax-free, tax-free withdrawals
