What these figures count
- State income tax, and state taxes on the business itself: franchise, LLC, S corp, gross receipts and excise taxes.
- Social Security and Medicare on both sides of an owner salary, federal unemployment tax and the state's new-employer rate.
- The 20% qualified business income deduction with its income limits and the professional-service rule.
- Yearly report fees, and a cost you can change for payroll and the business tax return.
Many S corp calculators leave out state taxes and the QBI deduction, which can make the election look better than it is.

How this page models New Hampshire (4)
- NH official pages (DRA, NHES, Secretary of State, RSA) were read directly in this run; quickstart.sos.nh.gov refused the reader, so the LLC annual report fee is cited from RSA 304-C:191.
- NHES sets new employers at 2.7% less the quarterly Trust Fund Reduction, which its Tax Rate Chart shows at 1.00% for every quarter of 2026 including Q3 and Q4, so 1.7% net applies for the whole year.
- The BET is 0.55% of the enterprise value tax base (compensation, interest and dividends paid) with filing required above $298,000 of gross receipts or base, but the schema has no such base, so it is approximated on net income and its credit against the BPT is not modelled.
- RSA 77-A:4 III lets owners deduct up to $75,000 as a record-keeping safe harbor or a larger substantiated reasonable compensation, and the $75,000 safe harbor is used as a typical figure.
