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.

What matters for marketing consultants

The IRS treats this work as a specified service trade or business, so the 20% QBI deduction phases out above $201,750 of taxable income (single). Paid advice is consulting under Treas. Reg. 1.199A-5(b)(2)(vii); doing the marketing work itself (running ads, making content) is not, so the answer depends on what clients pay for. law.cornell.edu
Pay figure is for market research analysts and marketing specialists, the closest SOC.
An S corp here adds New Jersey S corporation minimum tax (CBT).
