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.

At three profit levels

Profit	Salary used	Sole prop	LLC	LLC as S corp	C corp
$30,000	$21,000	$5,735	$5,735	$6,691	$7,758

$60,000	$36,000	$13,901	$13,901	$13,492	$16,670

Salary is the BLS median for the job ($35,790), capped at 70% of profit. Revenue 2.7 times profit. Single filer.

What matters for hair stylists

This work is not a specified service trade or business, so the 20% QBI deduction stays available above the income limit, subject to the wage limit. Hair care is not a listed field in Treas. Reg. 1.199A-5(b)(2). law.cornell.edu
Booth renters are self-employed and pay their own self-employment tax; at typical profits the S corp costs can outweigh the saving.

Questions

Should a hair stylist in Montana form an S corp?

At $40,000 of profit, not on these figures: the S corp costs $861 a year more than staying a sole proprietor.

Is an LLC worth it for a hair stylist in Montana?

For tax, a single-member LLC changes nothing: $8,417 a year against $8,417, the difference being Montana's LLC fees. It separates business liability and is the base for an S corp election.
