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.

What matters for software developers

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. Writing software is not on the list in Treas. Reg. 1.199A-5(b)(2), and consulting under (b)(2)(vii) covers only advice, not doing the work. law.cornell.edu
Many developers work on 1099 contracts; some clients only contract with an entity, which is a common reason to form an LLC early.
An S corp here adds New York S corporation fixed dollar minimum tax (Form CT-3-S).
