Why DIY Tax Filing Risks Cost High-Income Investors in Austin

Many high-income earners and business owners believe they can “save money” by using DIY tax software like TurboTax, H&R Block, or Jackson Hewitt. Unfortunately, this well-intentioned frugality often backfires. If you have complex investments, real estate portfolios, multiple income streams, or operate a business, using basic software or entry-level preparers can lead to costly errors, missed deductions, and red flags that trigger IRS audits.

At Lakeline Tax, headquartered in Cedar Park and serving Austin, we’ve helped dozens of clients clean up after the mistakes made by low-cost providers. Our expert team, including Enrolled Agents (EAs) with decades of experience, specializes in resolving IRS tax issues while creating long-term, proactive tax strategies that save clients tens of thousands of dollars annually.

Top 6 Reasons Your Investments May Trigger an IRS Audit

1. High Capital Gains or Losses

If your investment portfolio generates substantial capital gains or significant losses, it attracts IRS scrutiny. Misreporting capital gains on Schedule D or errors in Form 8949 are common audit triggers, especially when the numbers don’t align with brokerage-issued 1099-B forms. For high-net-worth investors in Austin, accurately tracking your cost basis and holding period is critical to avoid capital gains tax issues.

2. Unreported Rental or Investment Income

Failing to report all sources of passive income—such as short-term rentals (Airbnb), long-term property income, or earnings from partnerships—can easily result in underreporting penalties. The IRS matches your tax return against data reported via Form 1099-MISC, 1099-K, or K-1. If discrepancies are found, expect a CP2000 notice or worse. Lakeline Tax’s bookkeeping services help ensure all your income is reported correctly and consistently.

3. Improper Use of Self-Directed IRAs

High-income individuals often use self-directed IRAs or solo 401(k)s for real estate, private equity, or crypto investments. These accounts are subject to strict IRS rules under IRC Section 4975. A single prohibited transaction—such as using retirement funds to buy property for personal use—can result in the disqualification of the entire account and full taxation. Our team provides expert guidance to help investors remain compliant.

4. Inconsistent 1099 or K-1 Reporting

Many investors rely on multiple custodians or platforms. If your reported income doesn’t match the IRS records from 1099-Bs or Schedule K-1s, your return will likely be flagged. Errors in basis, passive loss limitations, or phantom income can result in large adjustments. Lakeline Tax performs detailed reconciliations to ensure your filings are audit-proof and fully optimized for tax efficiency.

5. Claiming Excessive Deductions Without Support

High-value deductions—such as home office expenses, investment advisory fees, real estate depreciation, or charitable contributions—must be well-supported. The IRS expects detailed logs, receipts, and proper substantiation. Failing to document large deductions can lead to disallowance and accuracy penalties. We help clients maintain IRS-compliant deduction records and use strategic planning to justify tax positions.

6. Using Generic Tax Software for Complex Returns

DIY software is not designed to manage multi-entity ownership structures, complex stock transactions, foreign income, or tax-loss harvesting strategies. TurboTax and similar platforms lack the sophistication required for tax planning at the high-net-worth level. Our clients often find that what they tried to save with software costs them 5–10x more in IRS penalties or missed tax opportunities. At Lakeline Tax, we customize every tax strategy based on your investments, entities, and goals.

Navigating IRS Tax Problems Without an Enrolled Agent: A Risky Gamble

Why certified EAs(Enrolled Agent) Are Essential for IRS Resolution

Enrolled Agents are federally licensed to represent taxpayers before the IRS. At Lakeline Tax, our EAs are trained to:

• Respond to IRS letters

• File amended returns

• Negotiate Offers in Compromise

• Set up IRS installment agreements

A Cedar Park tech entrepreneur came to us after receiving a CP2000 letter for unreported stock sale income. Their prior preparer didn’t respond, and the IRS assessed penalties. We filed an appeal, documented cost basis corrections, and reduced their liability from $46,000 to under $8,000.
