Frequently Asked Questions
How much self-employment tax do I owe on $100,000 in net income?
$14,130 in self-employment tax. SE tax applies to $92,350 (92.35% of net income) — covering both the employer (7.65%) and employee (7.65%) share of Social Security and Medicare. Your quarterly payment is $3,532.
When are quarterly estimated tax payments due for self-employed workers?
Due dates: April 15, June 16, September 15, and January 15. Missing a quarter triggers an underpayment penalty (currently ~8% APR on the shortfall). Pay via IRS Direct Pay or EFTPS. If SE income varies, you can base payments on 100% of prior year's tax to avoid penalties (110% if prior year AGI > $150K).
Can I deduct the self-employment tax I pay?
Yes — you can deduct $7,065 (half of SE tax) from gross income on Schedule 1 of your 1040. This reduces your federal income tax (and potentially state tax) but doesn't reduce the SE tax itself. It's a straightforward above-the-line deduction — no itemizing required.
Would an S-Corp reduce self-employment tax on $100,000?
Potentially, yes. As an S-Corp, you pay yourself a "reasonable salary" (say $50,000) and take the rest as a distribution. SE tax only applies to the salary portion. S-Corp setup costs $1,000–2,000/year in accounting — typically worthwhile above $50–60K net income.
