Form 941 for an S Corp With One Owner-Employee: 2026 Rules and a Worked Example
When you're the only person on your S corporation's payroll, you're both the employer and the employee. The corporation withholds tax from your paycheck, pays its own share of Social Security and Medicare, and reports all of it on Form 941, the same quarterly return a business with 50 employees files.
What's different for an owner is the pattern. Many owners pay themselves once a quarter or once a year, skip payroll in some quarters, or run health insurance through the company. Each of those changes what goes on the return and when the tax is due. For the general rules on every 941 form, see Form 941, Schedule B and 941-X in one place.
Filing Form 941 for S corp owner only employee payroll works like any other: once the corporation pays you wages, it files a 941 every quarter, including zero returns for quarters with no pay, until it files a final return. Your salary goes on lines 2, 3, 5a and 5c, and in 2026 the corporation pays 7.65% on top of the 7.65% withheld from you.
Form 941 for S corp owner only employee payroll: what you file
An S corporation that pays its owner wages has the same federal payroll duties as any employer. Here's the full list for 2026:
| Duty | When | What it covers |
|---|---|---|
| Form 941 | Every quarter after the first payroll: Q3 2026 by Nov 2, 2026; Q4 2026 by Feb 1, 2027 | Your wages, income tax withheld, and both halves of Social Security and Medicare |
| Tax deposits | Usually by the 15th of the month after payday (monthly depositor) | The same taxes, paid electronically |
| Form W-2 and W-3 | To you and the Social Security Administration by Feb 1, 2027 for 2026 wages | Your annual wages and withholding |
| Form 940 | Annually, Feb 1, 2027 for 2026 | Federal unemployment (FUTA) tax on your wages |
| State payroll filings | Set by your state | State income tax withholding and unemployment |
Sources: IRS Instructions for Form 941 (Rev. March 2026); Publication 15 (2026). Due dates reflect weekend rolls.
Line 1 of your 941 asks how many employees received pay for the pay period that includes the 12th of the quarter's last month. It's based on the pay period, not the payday: enter 1 if your paycheck covers a pay period that includes that date, and 0 if no pay period of yours does.
Paying yourself monthly, quarterly or once a year
Federal rules don't set how often an S corp owner must be paid. The pattern you choose decides your deposits and what each quarter's return looks like.
| Pattern | Form 941 each quarter | Deposits | Watch for |
|---|---|---|---|
| Monthly or every payday | Regular return every quarter | By the 15th of the next month if you're a monthly depositor | The most predictable option; easiest to show steady compensation |
| Once a quarter | Regular return every quarter | By the 15th of the month after the payday | Line 1 counts you only if your pay period includes the 12th of the quarter's last month |
| Once a year | Zero returns for quarters with no pay, one full return for the payday quarter | Either deposit by the 15th of the next month, or pay with the return if the prior quarter's line 12 was under $2,500 | One large payment; make sure the amount is still reasonable compensation |

New employers are monthly depositors for their first calendar year, and in 2026 most owner-only S corps stay monthly because their lookback total is far below $50,000. The full rules are in our guide to the 941 deposit schedule and how to pay.
Worked example: a $60,000 salary paid two ways in 2026
An owner sets a 2026 salary of $60,000, with $6,000 of federal income tax withheld for the year (an illustrative figure; actual withholding follows your W-4). Social Security is 12.4% and Medicare 2.9% of the wages, since the owner is far below the $184,500 Social Security wage base and the $200,000 Additional Medicare threshold.
Option A: $15,000 paid each quarter
| Form 941 line (each quarter) | Amount |
|---|---|
| 2 Wages | $15,000.00 |
| 3 Federal income tax withheld | $1,500.00 |
| 5a Social Security: $15,000 x 0.124 | $1,860.00 |
| 5c Medicare: $15,000 x 0.029 | $435.00 |
| 12 Total tax for the quarter | $3,795.00 |
Line 12 is $3,795 every quarter, so after the first quarter neither the current nor the prior quarter is under $2,500. Each quarter's tax has to be deposited, by the 15th of the month after each payday for a monthly depositor. A September 30, 2026 payday, for example, means a deposit by October 15, 2026.
Option B: $60,000 paid once, in December
| Quarter | Line 2 wages | Line 12 total tax | What's due |
|---|---|---|---|
| Q1 to Q3 2026 | $0 | $0 | Zero returns by their due dates |
| Q4 2026 | $60,000 | $15,180.00 ($6,000 + $7,440 + $1,740) | Deposit by Jan 15, 2027, or pay in full with a timely Q4 return by Feb 1, 2027 |
Illustrative 2026 figures. Rates from the March 2026 Instructions for Form 941.
The total 2026 tax is the same $15,180 either way. What changes is timing. Because the Q3 2026 return showed $0 on line 12, which is under $2,500, Publication 15 lets the corporation pay the Q4 tax with a timely filed Q4 return instead of depositing it, as long as it didn't owe $100,000 or more on any single day. Depositing by January 15 is also fine, and it's the safer choice if you aren't sure the prior quarter qualifies.
You can prepare your Form 941 from these totals, including a zero return, then print, sign and file it, and create your year-end W-2 the same way. ePaystubs prepares forms; it doesn't file them or make deposits for you.
Health insurance premiums: line 2 yes, lines 5a and 5c no
If you own more than 2% of the corporation, health and accident insurance premiums it pays for you in 2026 are wages on your W-2 (box 1) and subject to income tax withholding. When they're paid under a plan for all employees or a class of employees, they're not subject to Social Security, Medicare or FUTA tax, so they stay out of W-2 boxes 3 and 5.
On Form 941, that means the premiums go into line 2 but not lines 5a or 5c. Say the corporation in Option B treats $9,600 of 2026 premiums as wages in the December payroll:
| Q4 2026 line | Without premiums | With $9,600 of premiums |
|---|---|---|
| 2 Wages, tips and other compensation | $60,000 | $69,600 |
| 5a Taxable Social Security wages | $60,000 | $60,000 |
| 5c Taxable Medicare wages | $60,000 | $60,000 |
| 3 Income tax withheld | Per your W-4 | Per your W-4, on the higher wages |
Source: IRS S corporation compensation and medical insurance issues (updated March 3, 2026). Illustrative 2026 figures.
A line 2 that's higher than line 5a is normal here, not an error. You may then be able to take the self-employed health insurance deduction on your own return if you meet its conditions; that's a question for your tax preparer.
Quarters when you don't pay yourself
Once the corporation files its first Form 941, it files one every quarter, even with nothing to report, until it files a final return. A zero return shows 0 on lines 1, 2 and 12 and leaves the other zero lines blank. Don't check line 17 (that's for closing or stopping wages for good) or line 18 (that's for seasonal employers) just because you skipped a quarter.
Skipping a zero return can bring an IRS notice asking where it is. Our guide to zero, seasonal and final Form 941 covers each case, including what to do if you stop paying yourself permanently.
Can an owner-only S corp file Form 944 instead?
Possibly. If you expect the year's employment taxes to be $1,000 or less, you can ask the IRS to switch you to the annual Form 944. For 2026, the window was a call to 800-829-4933 between January 1 and April 1, 2026, or a letter postmarked between January 1 and March 16, 2026. You can only file Form 944 after the IRS sends written notice; without it, you keep filing Form 941.
In practice, $1,000 of total tax is a small payroll: at 15.3% of Social Security and Medicare alone, it's reached at about $6,536 of 2026 wages before any income tax withholding. Most owners paying a reasonable salary will be above it.
Reasonable compensation: why the salary matters on Form 941
An S corporation has to pay a shareholder who works in the business reasonable compensation before it makes non-wage distributions. The IRS can reclassify distributions as wages, which brings back the payroll tax, plus interest and penalties, and courts have backed it.
The IRS looks at factors such as your training and experience, duties, time devoted to the business, what comparable businesses pay for similar services, the company's dividend history and how bonuses are paid. Write down how you set your salary, and talk with a tax professional before you settle on an amount.
Whatever salary you choose, Form 941 reports exactly what you paid through payroll. Distributions never appear on it.
Claims about owner-only payroll to double-check
| What you might read | What the IRS rules say |
|---|---|
| "Check line 18 for a quarter when you paid yourself nothing." | Line 18 is for seasonal employers and line 17 for closing. A zero quarter is a normal return with 0 on lines 1, 2 and 12. |
| "The Q3 2026 Form 941 is due October 31." | October 31, 2026 is a Saturday, so it's due Monday, November 2, 2026. |
| "A once-a-year salary always has to be deposited by the 15th." | If the prior quarter's line 12 was under $2,500, you may pay with a timely return instead (no $100,000 day). |
| "Owner health premiums are taxed like any other wages." | For a more-than-2% shareholder under a plan, they're on line 2 but not lines 5a or 5c. |
Frequently Asked Questions
Yes, once the corporation pays you wages. It files Form 941 every quarter from then on, including zero returns for quarters with no paycheck, until it files a final return. The IRS may approve annual Form 944 instead if your 2026 taxes will be $1,000 or less.
Federal rules allow it, as long as the amount is reasonable compensation. You'd file zero returns for quarters without pay and a full return for the payday quarter. The tax is deposited by the 15th of the next month or, under the 2026 rules, paid with the return if the prior quarter's line 12 was under $2,500.
For a more-than-2% shareholder, premiums paid under a plan for employees are included on line 2 as wages subject to income tax withholding, but not on lines 5a or 5c, because in 2026 they still aren't subject to Social Security or Medicare tax.
Generally yes. A corporate officer who's paid wages is an employee for FUTA purposes, so the corporation files an annual Form 940 for 2026 by February 1, 2027 and deposits FUTA tax for any quarter in which it owes more than $500.
Enter 1 if you received pay for a pay period that includes March 12, June 12, September 12 or December 12, depending on the quarter. It follows the pay period, not the payday, so enter 0 if none of your pay periods that quarter covers that date.
