5. Neglecting Robust Bookkeeping and Substantiation!

Under IRS Section 162, business expenses must be both "ordinary and necessary." However, without a contemporaneous record-keeping system, these deductions can be easily challenged. Disorganized bookkeeping is the primary cause of missed tax savings.

The Fix:

• Implement Cloud Accounting: Use professional software to track income and expenses in real-time.
• Digitize Receipts: Maintain a digital repository of all receipts exceeding $75. Note the business purpose on each document.
• Log Business Mileage: For 2026, the standard mileage rate is 72.5 cents per mile. You must maintain a log detailing the date, destination, business purpose, and mileage for every trip. Commuting miles from home to your primary office are not deductible.

Consistent bookkeeping and business support allow for more aggressive, yet defensible, tax planning strategies.

6. Incorrect Information Reporting (Form 1099-K and TIN Mismatches)!

The reporting threshold for Form 1099-K has been significantly adjusted. For 2026, if your business receives $5,000 or more via third-party settlement organizations (such as Venmo, PayPal, or credit card processors), you will likely receive a 1099-K.

The Fix:

• Reconcile 1099-Ks: Ensure that the income reported on 1099-Ks matches your internal sales records. Discrepancies often trigger automated IRS notices.
• Verify TINs: Use the IRS e-services TIN Matching tool to confirm the Taxpayer Identification Numbers of your contractors before issuing 1099-NEC forms.
• Capture All Income: Do not assume that income not reported on a 1099 is tax-free. All business gross receipts must be reported.

7. Treating Tax as an Annual Event instead of Continuous Planning!

The most significant mistake is engaging with tax obligations only in the weeks prior to the April filing deadline. High-level tax strategy requires year-round attention to take advantage of shifting laws and economic incentives.

The Fix:

• Schedule Quarterly Reviews: Meet with your tax professional every three months to review financial statements and adjust tax projections.
• Optimize Retirement Contributions: Use SEP IRAs or Solo 401(k) plans to reduce your taxable income while building long-term wealth.
• Plan Asset Purchases: Coordinate with your advisor on Section 179 expensing or bonus depreciation for equipment purchases before the fiscal year ends.
