Summary of What This Blog Covers
- Five legal moves that reduce self-employment tax before 12/31
- S Corp pay, depreciation timing, SEHI/HSA, retirement choice, accountable plan
- Audit-ready steps + quick math
1. Calibrate S Corp Reasonable Compensation
Pay yourself enough salary to satisfy IRS but not a penny more — distributions escape SE tax.
2. Time Section 179 & Bonus Depreciation
Place equipment in service by 12/31 → immediate expense → lower net profit → lower SE tax base.
3. Align SEHI & HSA Choices
Self-employed health insurance deduction + HSA contributions reduce net earnings subject to SE tax.
4. Prioritize Solo 401(k) Over SEP
Solo 401(k) often gives bigger total contribution at same profit — employer share cuts SE tax base.
5. Use an Accountable Plan (S Corp)
Reimburse yourself tax-free for business expenses — company deduction without payroll tax hit.

Frequently Asked Questions
1) Do regular deductions reduce SE tax?
No — only those that lower net earnings from self-employment (like retirement employer contributions).
2) How much salary is “reasonable”?
Market rate for your role. We run comp data + duty split to document it cleanly.
3) HSA or SEHI — which first?
HSA contributions reduce SE tax base directly. SEHI is an above-the-line deduction.
4) Solo 401(k) vs SEP — which cuts SE tax more?
Solo 401(k) usually wins on total contribution room at the same profit.
5) What makes an accountable plan work?
Written policy + timely substantiation + business purpose = tax-free reimbursements.
