Analysis & insights
On $0 of self-employment income, you owe approximately $12,010 in SE tax (the 15.3% self-employment hit) + $5,401 in federal income tax = $17,411 total. That leaves -$17,411 take-home at an effective tax rate of 0.0%. At your income level, stay as a sole prop or single-member LLC — S-Corp admin costs would exceed the SE tax savings.
Low net SE income
Below the threshold where S-Corp election typically pays off. Stay as a sole prop / LLC for now.

Key insights
You're paying BOTH halves of FICA
Employees pay 7.65% FICA; their employer pays the other 7.65%. As a 1099 you pay both = 15.3% on top of income tax. This is the painful "self-employment tax" surprise.
You can deduct half of SE tax
The employer half of SE tax is an above-the-line deduction on your 1040. Already baked into the math here, but worth knowing for context.
