Summary of What This Blog Covers
- Five practical levers that shrink your self-employment (SE) tax while keeping cash smooth
- Exactly how to model an S Corp salary, fund retirement smart, run a true accountable plan, tune health coverage/HSA, and time income with safe harbors
- Field-tested checklists, micro-calculators, and a confident next step with Insogna
1. Model an S Corp Salary & Distributions
Pay reasonable salary (subject to payroll taxes) → take rest as distributions (no SE tax). Savings = 15.3% on amount shifted. Document with comp data, time logs, annual memo. Pitfall: too-low salary risks reclassification.
2. Fund Retirement the Smart Way (Solo 401(k)/SEP)
Employer contributions (up to 25% comp) + employee deferral (Solo 401(k)) → large deduction, reduces SE tax base. Roth option available. Spouse participation possible. Deadline: tax filing (extensions). Pitfall: missing deferral deadline.
3. Run a True Accountable Plan
Reimburse business expenses (mileage, home office, supplies) tax-free. Requires written policy, substantiation, return of excess. Deductible to business, no SE tax impact. Pitfall: no substantiation = disallowed.
4. Tune Health Coverage & HSA Strategy
S Corp: include health premiums in W-2 Box 1 → deductible to business. HSA: up to $4,300 single / $8,550 family (2025) + $1,000 catch-up if 55+. Reduces AGI and SE tax base. Pitfall: wrong W-2 coding.
5. Time Income & Use Safe Harbors
Time expenses/contributions/distributions for optimal year. Use safe harbor (100%/110% prior-year tax) to eliminate underpayment penalties. Re-run projections quarterly. Pitfall: ignoring income swings.

Frequently Asked Questions
1) How much salary is reasonable in an S Corp?
Market rate for actual duties. Use comp data, time logs, job description, company profit. Document annually with memo.
2) Solo 401(k) vs SEP IRA — which saves more?
Solo 401(k): employee deferral + employer contribution → higher limit. SEP IRA: employer-only, simpler, later deadline.
3) Accountable plan — what expenses qualify?
Mileage, home office, supplies, travel — anything ordinary & necessary. Requires substantiation (receipts/logs).
4) Health insurance — how to deduct in S Corp?
>2% shareholders: include premiums in W-2 Box 1 for deduction. Avoid self-employed health deduction issues.
5) Safe harbor — does it always work?
Yes — 100%/110% of prior-year tax eliminates underpayment penalties even if this year is higher.
