Question

Scott Stewart is the self-employed owner of Stewart Software. His estimated annual earnings are $48,000 and he expects to pay 18% of this amount in income tax. What will be his quarterly estimated tax payment for the second quarter? (For self-employed persons, social security tax is 12.4% of wages up to $106,800, and Medicare tax is 2.9% of all wages.)

Answer 1

I'd say 48000 * (.18+.124+.029) / 4 = 3996
