David Watson was a CPA in Des Moines. He knew the tax code for a living. He ran his earnings through an S-Corp. About $200,000 a year. He paid himself a salary of $24,000.

The IRS caught him. A federal appeals court upheld the ruling in 2012. Called $91,044 a reasonable salary. Re-tagged his distributions as wages. That part made the news.

The part that didn't? The clock.

You've heard the advice. Every CPA on YouTube says it. Every guy at the golf course repeats it. "Set up an S-Corp. Pay yourself a reasonable salary. Take the rest as distributions. Save on payroll taxes."

Fine. But here's what none of them explain.

When you pay yourself a salary, your S-Corp has to file Form 941 every quarter. That's the Employer's Quarterly Federal Tax Return. It reports what you withheld and what you owe. You file it four times a year.

If you skipped the salary, you skipped the filing. And if you skipped the filing, something breaks.

The IRS normally gets three years to come after you. That's §6501(a). File your return, and the three-year clock starts ticking. Most people know this.

Now read §6501(c)(3):

At any time.

Right.

No filed return means no clock. No clock means no limit. Every quarter you didn't file a 941 is still open. Not three years back. Not six. All of them. Back to the year you formed the S-Corp.

I mean, read that again. The three-year shield everyone counts on requires a filed return to start. No return, no shield. The lock you thought was bolted was never installed.

Now the penalties stack. One on top of the other.

The IRS re-tags your distributions as wages. The full FICA hit lands. That's 15.3% on the re-tagged amount. Employer share and employee share. Both.

Then the accuracy penalty. Twenty percent of the underpayment.

Then the failure-to-file penalty. Five percent per month, up to 25%, on each unfiled 941. Each quarter. Separately.

Then the big one. The Trust Fund Recovery Penalty. The employee's share of FICA, assessed at 100%, against you. Not your S-Corp. You. Your brokerage account. Your house. The corporate shell cracks open and this walks right through it.

Then interest. Seven percent a year right now. Compounding daily. On the early years, that interest has been running a long time.

Put a number on it.

Say your S-Corp nets $400,000. You've been paying yourself $50,000. The IRS says $200,000 is reasonable. That's $150,000 re-tagged per year.

FICA on that: $22,950 a year. Over ten open years, that's $229,500 just in back payroll tax. Add the accuracy penalty. Add failure-to-file on 40 unfiled quarters. Add a decade of compounding interest.

You're looking at $374,000.

That's the number you repeat at dinner. On what everyone told you was "just" a salary question.

This is not a thought experiment.

The IRS Strategic Operating Plan, published in 2023, names S-Corp reasonable compensation as an enforcement target. The Inflation Reduction Act gave them the funding. They are matching K-1 distributions against W-2 wages right now. If your S-Corp reports big distributions and a tiny salary, that match lights up a screen somewhere.

Look. The IRS wrote a rule. The rule says file your 941s. If you didn't file them, the clock never started. And they just got $80 billion to go looking.

David Watson was a CPA. He read this code for a living. The clock on his S-Corp never started either.
