The S Election Is A Tax Decision, Not A Logo.

9.4 The S Corporation Election

An S election is not a new company. It is a tax election that lets an owner-operator take a wage/distribution split: reasonable wages subject to payroll tax, remaining profit distributed without employment tax. That split is the whole point. If the wage is theater, the IRS can recharacterize the rest.

9.5 Reasonable Compensation

Shareholder-employees must take wages appropriate for the work. There is no published safe-harbor dollar. Courts look at duties, time, and comparable pay. A $1 salary and a large distribution is not planning. It is bait.

QBI And Built-in Gains

§199A (up to 20% of qualified business income, made permanent by OBBBA) can shrink or vanish if W-2 wages and SSTB limits are wrong. §1374 can tax pre-conversion appreciation if you came from C corporation status and sell inside the recognition period.

The Five Traps, One By One

• Reasonable compensation: the salary that defends the election
• Distributions vs salary: how the split works
• S election eligibility: the rules that quietly kill elections
• Built-in gains tax: the toll on C-to-S conversions
• Late S election relief: fixing the missed deadline
• S-corp vs C-corp: dodging double tax
• S-corp vs LLC: the election, not the entity
• The 2553 deadline: 2 months 15 days
• 2% shareholder fringe benefits that bite
• Stock and debt basis: what lets losses through
• AAA and excess distributions
• State PTET elections: dodging the SALT cap
• Terminating the S election
• QSUB: the S-corp inside your S-corp

Trap Questions, Answered

What is the S-corp trap?

The election saves employment tax only when the salary is reasonable, eligibility holds, and conversions are timed. Each condition fails silently — the trap is assuming the election alone did the work.

LLC or S-corp — which comes first?

Usually the LLC first, then the S election when profit justifies payroll. Electing on day one buys overhead before savings.

Where do S elections blow up?

Zero salaries, ineligible shareholders discovered years later, and C-to-S conversions sold inside the 5-year built-in-gains window. All three have their own page above.
