Form 1125-E: S-Corp Officer Compensation

Part of WageProof's complete guide to S-corp reasonable compensation.

Form 1125-E is a one-page IRS form that lists what a corporation paid each of its officers. Officers are the people who hold titles like president, treasurer or secretary. In many small S corporations, the owner who runs the business is also its president, so the form may list just that one person.

The form isn't required for every corporation. An S corporation attaches it to its tax return, Form 1120-S, only when its total receipts for the year are $500,000 or more and it is deducting pay to its officers. The IRS has the form and its instructions on its website.

This guide explains what the form is for, who has to file it, what goes in each column, and why the officer pay it reports matters so much at an S corporation.

The short version

• Form 1125-E is required when total receipts are $500,000 or more and the corporation deducts officer pay.
• It lists each officer's name, Social Security number, share of time spent on the business, share of stock owned, and pay.
• The amount on the form's last line, line 4, goes on Form 1120-S, line 7, "Compensation of officers."
• It reports salary and other pay. Distributions of profit are reported somewhere else on the return.
• At an S corporation, the officer pay it reports has to be reasonable compensation, meaning roughly what the business would pay someone else to do the same work.

What Form 1125-E is for

An S corporation is a corporation whose profits pass through to its owners and are taxed on their personal returns. Like any business, it can deduct the wages it pays, including pay to its officers. On Form 1120-S, officer pay has its own line, line 7.

For a larger business, the IRS wants the detail behind that one number. The instructions say the form exists "to provide a detailed report of the deduction for compensation of officers." In other words, it shows who was paid and how much.

The form has been around since 2011. For regular corporations, it took the place of a schedule that used to be printed inside their tax return, Form 1120. They started using Form 1125-E for tax years beginning in 2011, and S corporations have used it for tax years beginning after 2012.

Form 1125-E is a different form from Schedule E of Form 1040, which individuals use to report income from rentals, royalties, partnerships and S corporations. The names are easy to mix up. An owner's share of the S corporation's profit goes on Schedule E, but the officer pay on Form 1125-E does not.

When Form 1125-E is required

The IRS instructions set two conditions, and both have to be met. The corporation must have total receipts of $500,000 or more, and it must deduct compensation for officers.

Total receipts means more than sales. The Form 1120-S instructions define it as the business's gross receipts plus other income it reported for the year, including interest, dividends, royalties, rental income and gains from selling property. They list the exact lines of the return to add up. (A note for preparers: the separate Form 1125-E instructions were last revised in 2018 and still point to older line numbers on Form 8825, lines 2, 19 and 20a. The current 1120-S instructions use Form 8825 lines 2, 21 and 22a.)

Below $500,000, there's no form. The corporation enters its officer pay directly on Form 1120-S, line 7.

A corporation that pays its officers nothing doesn't file the form either, because it has no officer pay to deduct. That isn't a loophole. The Form 1120-S instructions for line 7 begin with a warning that payments to an officer "must be treated as wages to the extent the amounts are reasonable compensation for services rendered to the corporation." An owner who works in the business and takes money out of it is expected to be on payroll, whether or not the form is required.

The form is filed with the S corporation's return. For a calendar-year S corporation, the 2026 return is due March 15, 2027.

How to fill in Form 1125-E, column by column

Line 1 of the form is a small table with one row per officer. Every officer goes on it.

• (a) Name of officer. Each officer's name. Who counts as an officer depends on the law of the state (or country) where the corporation was formed.
• (b) Social Security number. The officer's Social Security number. The instructions allow just the last four digits.
• (c) Percent of time devoted to business. The share of the officer's working time spent on this business.
• (d) Percent of common stock owned. The officer's share of the corporation's stock.
• (e) Percent of preferred stock owned. An S corporation can have only one class of stock, so this column is ordinarily blank.
• (f) Amount of compensation. The officer's total deductible pay for the year, such as salary, bonuses, commissions and taxable fringe benefits.

Column (f) has one rule specific to S corporations. For an officer who owns more than 2% of the stock at any time during the year (counting stock owned by close family members), it includes fringe benefits the corporation paid on that officer's behalf, such as health insurance premiums. For officers who own 2% or less, those fringe benefits are left out of column (f).

The single-class-of-stock rule in column (e) has one wrinkle. Shares that differ only in voting rights still count as one class, so an S corporation can have voting and non-voting common stock. Both go in column (d).

Below the table are three lines:

• Line 2 is the total of column (f).
• Line 3 is officer pay that the corporation already deducted somewhere else on the return, so that it isn't counted twice. The instructions give examples: pay included in cost of goods sold, and amounts an officer chose to put into a 401(k), a salary-reduction SEP or a SIMPLE IRA. If the corporation claims a tax credit for wages it paid, it may also need to reduce its deduction for officer pay (IRC §280C).
• Line 4 is line 2 minus line 3. That number goes on Form 1120-S, line 7.

Does Form 1125-E show salary or distributions?

Only salary and other compensation. Distributions, the money owners take out as their share of the profit, are reported separately on Schedule K of Form 1120-S, line 16d.

Both numbers are on the same tax return, though. Anyone reading an S corporation's return can see how much the owners were paid as officers and how much they took as distributions, and Form 1125-E adds each officer's share of time in the business next to their pay.

Why officer pay has to be reasonable

The split between salary and distributions matters at an S corporation because the two are taxed differently. Salary carries Social Security and Medicare taxes, 15.3% in total on most salaries, and distributions don't. An owner could save tax by paying themselves very little and taking the rest as distributions, so the IRS requires an owner who works in the business to be paid a reasonable salary first.

"Reasonable" means roughly what the business would have to pay someone else to do the same work in the same area. There's no formula for it. The IRS fact sheet on the subject says "there are no specific guidelines for reasonable compensation in the Code or the Regulations" (FS-2008-25). Instead, it lists the factors courts weigh, such as the owner's training and experience, their duties, and what comparable businesses pay for similar work. One of those factors is the time and effort the owner devotes to the business, and column (c) of Form 1125-E records the time part of it, as a percentage. The Nine IRS Factors goes through each one.

A related rule covers family members. If a member of a shareholder's family works for the corporation without being paid reasonable compensation, the IRS can adjust the amounts that person and the shareholders report to reflect what the work was worth (IRC §1366(e)).

Checking Form 1125-E against the W-2s

Form 1125-E doesn't set anyone's pay. For an officer who owns stock, it reports what payroll already paid. Wages count in the year they are paid, so an officer's pay for 2026 is whatever went through payroll by the last paycheck of 2026. The W-2s and the last quarterly payroll tax return (Form 941) for 2026 are due February 1, 2027, about six weeks before the 1120-S.

That makes the W-2s the natural thing to check column (f) against, but the numbers won't always match exactly. Health insurance premiums for an owner who holds more than 2% of the stock are included in column (f) and in box 1 of the owner's W-2. When the coverage is part of a plan for all employees or a group of them, they aren't subject to Social Security or Medicare tax, so they're left out of W-2 boxes 3 and 5 (IRS guidance). Amounts on line 3, such as 401(k) contributions, explain other differences. The goal is to reconcile the form to the W-2s and be able to explain every difference.

Because the salary is fixed by the last payroll of the year, the review belongs in November, ahead of that payroll. The year-end guide for CPA firms walks through that review.

What happens if officer pay is too low

If the IRS decides an owner's salary was too low, it can treat part of the owner's distributions as wages. The corporation then owes the Social Security and Medicare tax that should have been paid on them, including the employee's half that it should have withheld, plus interest.

Penalties depend on the facts. In two 2013 Tax Court cases, Glass Blocks Unlimited v. Commissioner and Sean McAlary Ltd., Inc. v. Commissioner, the court upheld penalties for failing to file payroll tax returns and failing to deposit payroll taxes. There is also a possible 20% accuracy-related penalty under IRC §6662, which is not automatic.

The IRS generally has three years from April 15 of the year after the payroll returns cover (or from when they were filed, if later) to assess back payroll tax, and no time limit if they were never filed. What happens when the IRS challenges an S-corp salary walks through an examination step by step.

Documenting the officer pay figure

The number in column (f) is easiest to stand behind when there's a written record of how it was set, made before the year's last payroll. That record, often called a reasonable compensation study, describes what the owner does and how their time divides, names the method used, and identifies the wage data behind the figure, including its source, its year, the geographic area and the experience level.

WageProof builds that study. Its cost and market approach reports use Bureau of Labor Statistics wage data. The sample report shows a finished one, the methodology page explains the calculations, and the reasonable compensation calculator shows what information a study needs. CPA firms can see how others use it on WageProof for CPAs and EAs.
