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.

Recommended actions(4)

Set aside 25-30% of every payment received

High priority

Open a separate "tax savings" account; transfer 25-30% the day you receive each client payment. Eliminates the April surprise.

Impact: On $100K of SE income, that's $25-30K saved by April — the actual amount you'll owe.

Pay quarterly estimated taxes

High priority

Due Apr 15, Jun 15, Sep 15, Jan 15. Use IRS Form 1040-ES. Underpayment penalty applies if you owe more than $1,000 at filing.

Impact: Avoids ~8% APR underpayment penalty from the IRS.

Max a Solo 401(k) or SEP-IRA

Medium priority

2025 Solo 401(k) limit: $70K total ($23.5K employee + ~25% employer). SEP-IRA: 25% of net SE income up to $70K. Reduces taxable income at your marginal rate.

Impact: At a 24% bracket, contributing $20K saves $4,800 in federal taxes alone.

FAQ

Q: What happens if I don't pay quarterly taxes?

The IRS charges an underpayment penalty (currently ~8% annualized). If you owe more than $1,000 at year-end, you'll likely owe penalties.

Q: Can I deduct my home office?

Yes, if you use a dedicated space regularly and exclusively for business. Use the simplified method ($5/sq ft, max 300 sq ft) or actual expense method.
