How you set up payroll as a self-employed owner depends first on how your business is organized. If you run a sole proprietorship or a partnership, you don’t run payroll on yourself at all — you pay self-employment tax through quarterly estimated payments. If you’ve elected S-corporation status and perform services for the business, you’re required to pay yourself a reasonable salary through formal payroll, with withholdings, deposits, and quarterly filings. The rest of this guide walks through the S-corp setup, because that’s where “payroll” actually applies.
Do You Need Payroll at All?
The IRS treats sole proprietors and partners as owners, not employees. You can’t cut yourself a W-2 paycheck. Instead, you pay self-employment tax on net business earnings at a combined 15.3 percent — 12.4 percent for Social Security and 2.9 percent for Medicare — reported on Schedule SE, with quarterly estimated payments covering both self-employment tax and income tax.1Internal Revenue Service. Self-Employed Individuals Tax Center
An S-corporation is different. An S-corp shareholder who provides services must receive a reasonable salary through payroll before taking additional profit distributions, and the corporation must report and withhold employment taxes on that salary just like any other employer.2Internal Revenue Service. S Corporation Employees, Shareholders and Corporate Officers Distributions beyond that salary aren’t subject to Social Security or Medicare tax, which is exactly why the IRS pays close attention to whether the salary portion is high enough.
Set Your Reasonable Salary First
Before any paperwork, decide what you’re going to pay yourself. Federal regulations let a business deduct salaries only when they’re genuinely paid for services and reflect what similar roles command in the marketplace.3eCFR. 26 CFR 1.162-7 – Compensation for Personal Services The IRS and the courts weigh several factors when they check whether an owner’s salary is reasonable:
- Your training, experience, and qualifications for the role.
- The duties and responsibilities you actually handle.
- The time and effort you put into the business.
- What comparable businesses pay for similar positions.
- Your history of distributions — a minimal salary alongside large distributions signals an artificially low wage.
- Any formal compensation agreements.
If the IRS decides your salary is unreasonably low, it can reclassify distributions as wages, which brings back employment taxes, interest, and penalties. Document how you arrived at the figure — comparable pay data, your role, hours — and keep that file.
Get Your EIN and S-Corp Election in Place
You need a federal Employer Identification Number before you can process a paycheck. Apply on Form SS-4 with your business’s legal name, any trade name, the responsible party’s Social Security number, and the business address. The online application issues the EIN immediately.
If you’re forming the S-corp or converting an existing entity, file Form 2553 — not Form 8832, which handles general entity classification. Form 2553 needs the signatures of all shareholders and the effective date of the election.5Internal Revenue Service. About Form 2553, Election by a Small Business Corporation For a calendar-year business, the form must be filed no more than two months and 15 days after the start of the tax year the election is to apply to, meaning no later than March 15 for a January 1 effective date; you can also file any time in the preceding tax year.6Internal Revenue Service. Instructions for Form 2553 Miss the window and the election slips to the following year, which delays your ability to split income between salary and distributions.
Register for Federal and State Payroll Accounts
EFTPS
Once you have the EIN, enroll in the Electronic Federal Tax Payment System. EFTPS is how you send withheld income tax and FICA to the Treasury.7Internal Revenue Service. EFTPS – The Electronic Federal Tax Payment System Enrollment can take up to two weeks because the PIN arrives by mail, so start well before your first pay date.
State Withholding and Unemployment
Register with your state’s department of labor or revenue for state unemployment insurance and state income tax withholding accounts. These generally require your EIN and a description of your business. New-employer SUI rates and taxable wage bases vary widely — bases range from as low as $7,000 to over $60,000 per employee, and some states also require disability or paid family leave withholdings. Check what your state requires before your first payroll run.
New Hire Reporting
Federal law requires reporting every newly hired employee — including an S-corp owner going on payroll — to the state’s new hire directory within 20 days of hire, and some states set shorter deadlines.8Administration for Children and Families. New Hire Reporting – Answers to Employer Questions Confirm your state’s deadline and submission method.
Run Each Paycheck
Every pay period, calculate gross salary and subtract withholdings before transferring the net to your personal account.
FICA
Withhold 6.2 percent for Social Security and 1.45 percent for Medicare from gross wages. The S-corp matches both, bringing the combined FICA cost to 15.3 percent of taxable salary.9Internal Revenue Service. Topic No. 751, Social Security and Medicare Withholding Rates Social Security applies only to wages up to $184,500 in 2026; wages above that aren’t subject to the 6.2 percent withholding.10Social Security Administration. Contribution and Benefit Base Medicare has no wage cap.
If total Medicare wages pass $200,000 for the year (single filers), an additional 0.9 percent Medicare tax applies on wages above that threshold. The thresholds are $250,000 for married filing jointly and $125,000 for married filing separately. The employer doesn’t match this Additional Medicare Tax.11Internal Revenue Service. Topic No. 560, Additional Medicare Tax
Federal Income Tax
Federal income tax withholding follows your own Form W-4 and the tax tables in Publication 15 (Circular E). As the sole employee, you have direct control over the withholding amount each pay period, and many S-corp owners set it to roughly match projected annual income tax liability.
Making the Payment
Move funds from the business bank account to your personal account by ACH transfer or a check written on the business account. Generate a pay stub for each payment showing gross pay, each withholding, and net pay. Most payroll software produces stubs automatically. A monthly or semi-monthly schedule keeps the administrative load down while giving you steady income.
File Your Quarterly and Annual Returns
Form 941
Each quarter, file Form 941 to report total wages, federal income tax withheld, Social Security and Medicare taxes withheld, and the employer’s matching FICA. Due dates fall on the last day of the month after the quarter closes:12Internal Revenue Service. Instructions for Form 941
- Q1 (January–March): April 30
- Q2 (April–June): July 31
- Q3 (July–September): October 31
- Q4 (October–December): January 31
If your total annual employment tax liability is $1,000 or less, you may qualify to file Form 944 once a year in place of quarterly 941s, but the IRS must notify you or approve your request before you switch.13Internal Revenue Service. Instructions for Form 944
Form 940
File Form 940 annually for federal unemployment tax. FUTA is 6.0 percent on the first $7,000 of wages paid to each employee, and most employers qualify for a credit of up to 5.4 percent, bringing the effective rate to 0.6 percent.14Internal Revenue Service. Instructions for Form 940 FUTA is employer-paid only; it’s never withheld from wages.
Form W-2
Issue yourself a W-2 for the year’s wages and withholdings, furnish it to yourself as the employee, and file with the Social Security Administration by January 31 of the following year. If January 31 falls on a weekend, the deadline moves to the next business day.15Internal Revenue Service. 2026 General Instructions for Forms W-2 and W-3 Employers filing 10 or more information returns must submit them electronically.
Penalties Worth Avoiding
Payroll tax enforcement is aggressive, and the amounts add up fast even for a one-person S-corp.
Late deposits of withheld taxes bring tiered penalties:16Internal Revenue Service. Failure to Deposit Penalty
- 1–5 calendar days late: 2 percent of the unpaid deposit
- 6–15 calendar days late: 5 percent
- More than 15 calendar days late: 10 percent
- More than 10 days after the first IRS notice: 15 percent
The percentages don’t stack. A deposit more than 15 days late incurs a flat 10 percent, not the sum of the earlier tiers.
Filing Form 941 or Form 940 late adds a separate 5 percent penalty on the unpaid tax for each month or partial month the return remains unfiled.17Internal Revenue Service. Failure to File Penalty
The most serious exposure is the trust fund recovery penalty. The federal income tax and employee share of FICA you withhold are treated as trust fund taxes — money the government considers the employee’s, held in trust by the employer. If a responsible person willfully fails to pay those amounts over, the IRS can assess a penalty equal to the full amount of the unpaid trust fund taxes, personally, even when the business is a corporation.18Office of the Law Revision Counsel. 26 USC 6672 – Failure to Collect and Pay Over Tax The corporate liability shield does not stop it.
Handle Health Insurance the Right Way
If you own more than 2 percent of the S-corp and the business pays your health insurance or reimburses your premiums, those amounts must be included in your W-2 wages (Box 1) as additional compensation, subject to federal income tax withholding.19Internal Revenue Service. S Corporation Compensation and Medical Insurance Issues The offset is that you can then claim an above-the-line deduction for the premiums on your personal return.
Premiums reported this way are not included in Boxes 3 and 5, so they aren’t subject to Social Security, Medicare, or FUTA tax.19Internal Revenue Service. S Corporation Compensation and Medical Insurance Issues If your spouse is eligible for employer-subsidized coverage through another job, you can’t claim the self-employed health insurance deduction.
Line Up Retirement Contributions With Your Salary
Once you’re on payroll, tax-advantaged retirement plans key off your W-2 compensation.
A SEP IRA lets the S-corp contribute up to 25 percent of your W-2 compensation, capped at $69,000 for 2026.20Internal Revenue Service. SEP Contribution Limits (Including Grandfathered SARSEPs) Contributions come entirely from the employer and are deductible as a business expense; there’s no employee deferral.
A Solo 401(k) gives you more flexibility. Employee elective deferrals go up to $24,500 in 2026, plus employer profit-sharing contributions of up to 25 percent of your W-2 wages.21Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026 Age 50 and older adds an $8,000 catch-up; ages 60 through 63 get an $11,250 catch-up. Combined contributions can’t exceed the annual additions limit.22Internal Revenue Service. One-Participant 401(k) Plans
Because both plans base employer contributions on W-2 salary, a salary set too low caps your retirement savings and reduces the Social Security earnings on your record.
Keep the Records
Keep all employment tax records for at least four years after the date the fourth-quarter return is filed for the year or the date the tax is paid, whichever is later.23Internal Revenue Service. Employment Tax Recordkeeping Your file should include:
- Copies of every Form 941 (or 944), Form 940, and Form W-2 you submit.
- Bank statements showing each payroll transfer from the business to your personal account.
- The analysis and comparable pay data behind your reasonable salary figure.
- Pay stubs showing gross pay, individual withholdings, and net pay for every period.
Those records defend both your payroll compliance and your reasonable compensation determination if either is ever questioned.
