Taking money out of your S-corp as a “loan” sounds smart. You move cash to yourself, skip the payroll taxes, and put a receivable on the books. No FICA, no W-2, no problem.
The IRS has seen this one a lot. They know how it works.
If the loan doesn’t actually look like a loan — and most of them don’t — the IRS reclassifies the money as wages. Then you owe the payroll taxes you were trying to avoid, plus penalties, plus interest, plus the interest your corporation should have been charging you on the loan but wasn’t. The S-corp structure doesn’t protect you from this. There’s no corporate shield against a payroll tax reclassification.
What makes a shareholder loan legitimate
A real loan from your own S-corp has specific requirements. All of them matter, and none of them are optional.
A signed promissory note. It has to be in writing, dated when you actually take the money — not backdated after the auditor asks about it. The note needs to state the principal amount, the interest rate, and the repayment schedule.
A real interest rate. The IRS publishes the Applicable Federal Rate (AFR) monthly. Your loan has to charge at least that rate. In mid-2026, the short-term AFR is in the 4–5% range. If you charge nothing — or below the AFR — the IRS imputes the missing interest as additional income to you and a deemed payment from the corporation. You end up paying taxes on money you never actually received.
Actual repayments. Not repayment on paper. The money has to come back to the company on something close to the schedule in the note. If you’re “repaying” the loan by taking another draw the same week, the IRS doesn’t treat that as a repayment. It treats it as a running balance that isn’t a loan at all.
The loan has to appear on the books. It should show as a receivable from the shareholder on the corporate balance sheet. If your bookkeeper doesn’t know the loan exists, it won’t hold up. Auditors look at the books. An unrecorded “loan” is a distribution.
What happens when the IRS says it’s not a loan
They reclassify it as wages, and several things happen at once.
The corporation owes the employer share of FICA — 7.65% of the reclassified amount. You owe the employee share on your personal return — another 7.65%. The company should have been withholding those taxes quarterly and remitting them to the IRS. Since it didn’t, there are late-deposit penalties on the payroll side on top of the reclassified tax.
If the reclassified amount makes your total compensation look too low relative to what you actually did for the business, you may also face the reasonable salary argument at the same time — two separate audit issues running in parallel on the same return.
The payroll tax piece is worth taking seriously. Unpaid payroll taxes — taxes that were supposed to be withheld and remitted and weren’t — carry personal liability for the “responsible person” in the business. That’s not just a corporate problem. We covered this separately in the post on what happens when payroll taxes go unpaid. The IRS can and does come after the individual, not just the company.
If you've been taking draws from your S-corp labeled as loans without a signed note and actual repayments, it's worth cleaning this up before the IRS finds it. Schedule a review.
This is different from distributions
Taking a distribution from your S-corp is allowed and doesn’t trigger payroll taxes — as long as you’re already paying yourself a reasonable W-2 salary. The distribution reduces the retained earnings of the business and shows up on your K-1 as a return of basis. Clean, documented, understood.
The problem is when owners skip the salary step, take draws they call loans, and try to avoid both the payroll taxes and the scrutiny that comes with low compensation. The IRS looks at the salary-to-distribution ratio on S-corp returns. A “loan” that’s really avoiding salary scrutiny stands out even more.
The foundation here is getting your compensation structure right from the start. The post on S-corp reasonable salary covers how the IRS defines “reasonable” and how to document it correctly. The shareholder loan question is downstream of that — if your salary is in the right place, the pressure to take money out as loans mostly disappears.
If you’re also running personal and business funds together, that’s a separate problem that makes the loan argument even harder to win. Mixing personal and business accounts is the first thing an auditor looks for. We covered that in the post on commingling funds.

S-corp money flows are more complicated than they look, and the IRS knows it. If you have shareholder loans on the books and aren't sure they meet the standard, let's go through it before you file. Book a conversation here.
