You can deduct $6 per square foot of your home office, up to 300 square feet, for a maximum deduction of $1,800.
Wrong rate. The simplified method is $5/sqft, not $6. This would overstate the deduction and trigger an IRS mismatch.
Simplified method: $5 per square foot, maximum 300 sqft = $1,500 cap. Actual method may yield more if mortgage interest + property tax + utilities are high.
Rev. Proc. 2013-13, §4.01 — IRC §280A(c)(5)
Restaurant meals are 100% deductible for business purposes. You can deduct the full cost of meals with clients at restaurants.
Outdated. The 100% deduction for restaurant meals was a temporary COVID provision (2021–2022). Since 2023, business meals are back to 50%.
Business meals: 50% deductible. The temporary 100% restaurant meal deduction under the Consolidated Appropriations Act expired after December 31, 2022.
IRC §274(n)(1) — CAA 2021 §210 (expired 12/31/2022)
Your QBI deduction is 20% of your qualified business income. At $195,000 income, you get the full 20% deduction.
Ignores the phase-out cliff. For single filers, the QBI deduction begins phasing out at $191,950 (2025). At $195,000 the taxpayer is in the phase-in range and the computation changes dramatically.
Taxable income $195,000 exceeds the §199A threshold of $191,950 (single, 2025). You are $3,050 into the $50,000 phase-in range. The deduction is reduced — the skill computes the exact phase-in amount based on your W-2 wages and UBIA.
IRC §199A(b)(3)(B), Rev. Proc. 2024-40 §3.28
Self-employment tax is 15.3% of your net profit. On $150,000, that's $22,950 in SE tax.
Missing the 92.35% adjustment. SE tax applies to 92.35% of net earnings, not the full amount. Also misses the Social Security wage base cap ($176,100 for 2025) and the Additional Medicare Tax at 0.9% above $200K.
SE earnings = $150,000 × 92.35% = $138,525. SS tax (12.4%) on first $176,100 of combined wages + SE = $17,177.10. Medicare (2.9%) on full $138,525 = $4,017.23. Total SE tax = $21,194.33. Deductible half = $10,597.17.

You can contribute up to $23,500 as an employee, plus 25% of your net profit ($50,000) as an employer contribution, for a total of $73,500.
The employer contribution base is wrong. It’s 20% (not 25%) of net self-employment income after deducting half of SE tax. The 25% figure applies to W-2 employees of corporations, not sole proprietors.
Employee deferral: $23,500 (2025). Employer contribution: 20% of (net SE income minus half of SE tax). Net SE = $200,000. Half SE tax ≈ $15,922. Employer base = $184,078 × 20% = $36,816. Total = $60,316. Overall cap: $70,000 (2025).
IRC §401(a)(17), IRC §404(a)(8)(D), IRS Pub 560 Ch. 5
You should pay 90% of your current year tax liability in quarterly estimated payments to avoid penalties.
Incomplete. The safe harbor is the LESSER of 90% current year OR 100% prior year (110% if prior year AGI > $150,000). Most freelancers with growing income should use the prior-year safe harbor — it’s almost always lower and avoids the guessing game.
Prior year AGI > $150,000 → 110% prior-year safe harbor applies. Required annual payment = 110% × prior year total tax. Divide by 4 for quarterly amounts. This avoids underpayment penalty regardless of current year income growth.
