Summary
The video walks through a multiple‑choice question from Farhat Lectures that asks candidates to compute the self‑employment tax owed by “Kate,” who earned $15,000 from self‑employment in addition to a $42,000 salary.
It clarifies that only the self‑employment income is taxable, reduced by the 7.65% employer‑share exemption (92.35% factor), yielding $13,852. Applying the 15.3% combined Social Security and Medicare rate produces a tax liability of $2,119. The deduction for AGI is half of that amount, $1,060, because the self‑employment tax is partially deductible.
The instructor emphasizes the breakdown—12.4% for Social Security (both employee and employer portions) and 2.9% for Medicare—and warns students not to confuse the tax due with the deductible portion. He also highlights the “half of your social security, your employee, and your employer” phrasing as a mnemonic.
Mastering this calculation is essential for CPA exam takers and practicing accountants, as it directly affects filing accuracy and tax‑planning strategies for freelancers and gig‑economy workers.
