Model notes

Assumptions: single filer, standard deduction ($16,100), no other income, no dependents, 2026 estimated brackets and thresholds, state income tax from per-state single-filer tables on the same AGI for both entities. The QBI deduction uses the 20% tentative deduction with the taxable-income phase-out; the W-2 wage limitation is not applied in this estimate. The employer half of FICA is deducted before the K-1 passes through. The Hearth Legacy Program deduction snaps to whole ADRA and token-package units, and its cost is shown as the estimated down payment under 10-year financing.

Not modeled: PTET elections, entity-level state taxes on S corps (for example CA franchise tax), retirement plan contributions, health insurance premiums for a 2%+ shareholder, itemized deductions, other income sources, SSTB status, local taxes, or multi-owner structures. The reasonable-compensation zone shown is illustrative, not a legal safe harbor; no IRS safe harbor exists.

This is a planning estimate, not tax advice. Verify any election decision with a licensed CPA.

What it shows

The entity difference, grounded in the client's facts.

The sample above is a Virginia conversation you can drive live. After you sign in, you run the client's state: payroll tax against self-employment tax. It frames the conversation. The documented plan is still firm work.

For the client

A leave-behind that explains the election.

A one-page advisory summary your firm can print or email after a calculator run: the salary and distribution split, what it can save, and the costs and duties that come with it. No pricing on it, and your firm stays the advisor.

Next step

The election answers one question. The salary answers the next.

Every S-corp the calculator argues for needs a defensible comp figure behind it. That's HearthRC Defense: three methods reconciled into one documented number, wholesale to your firm, delivered under your brand.
