Worked Example: Overturning an SFR and Securing Penalty Abatement
Scenario. In 2027, Ken, a freelance graphic designer, hires you. He did not file his 2025 tax return. The IRS prepared an SFR and issued a notice assessing $22,000 in tax. Your investigation reveals the following for Tax Year 2025:
- | Item | Amount | | :--- | :--- | | Gross Income (Forms 1099-NEC) | $95,000 | | Ordinary & Necessary Business Expenses | $40,000 | | Estimated Tax Payments Made | $5,000 | | Filing Status | Single | | Prior Tax History (2022-2024) | All returns filed on time, no penalties. |
- Your task is to file the correct 2025 return, correct the IRS assessment, and request penalty relief.
- Step 1: Prepare the Correct 2025 Return (Form 1040 & Schedule C) First, calculate Ken's actual net profit and tax liability. The SFR is ignored. Net Self-Employment Profit: $95,000 (Gross) - $40,000 (Expenses) = $55,000
- Step 2: Calculate Correct 2025 Tax Liability Self-Employment Tax: ($55,000 × 92.35%) × 15.3% = $50,792.50 × 0.153 = $7,771 AGI: $55,000 (Net Profit) - $3,886 (1/2 SE Tax Deduction) = $51,114 Taxable Income: $51,114 (AGI) - $15,750 (2025 Standard Deduction - Single) = $35,364 Income Tax (2025 rates): (10% × $11,925) + (12% × ($35,364 - $11,925)) = $1,193 + $2,813 = $4,006 Total Correct Tax: $7,771 (SE Tax) + $4,006 (Income Tax) = $11,777
