Payroll & Self-Employment Tax: The Complete Guide

Hire your first employee and you become a tax collector. Stay solo and you pay a special tax most employees never see. Either way, payroll and self-employment taxes are the part of the tax system that punishes ignorance fastest — the penalties are steep, personal, and they accrue while you are busy running the business.

This guide to payroll self-employment tax covers both systems under 2026 rules: payroll taxes for employers and employees, self-employment tax for owners and freelancers, the new tips and overtime deductions, and every deadline you must meet.

Payroll Tax vs Self-Employment Tax: The 30-Second Version

Both taxes fund the same programs — Social Security and Medicare — but they apply to different people:

• Payroll tax applies when you have employees. You withhold the employee’s share from their pay, pay the employer’s matching share yourself, and remit both to the IRS.
• Self-employment tax applies when you are the worker — sole proprietors, partners, LLC members and freelancers. You pay both halves yourself: 15.3% on your net earnings.

An S corporation owner lives in both worlds: payroll tax on their salary, neither payroll nor self-employment tax on the remaining profit distributions.

Payroll tax rates at a glance (2026)

Tax	2026 rate	Applies to	Who pays

FUTA	6.0%, or 0.6% with the full 5.4% state credit	First $7,000 of each employee’s wages	Employer only
Federal income tax withholding	Varies — set by Form W-4	Taxable wages	Employee’s tax — you withhold it

How to run payroll in 6 steps

Running payroll is the same six-step loop every pay period. Master it once and every payday runs itself:

1. Work out gross pay. Hours × rate for hourly staff, or salary ÷ pay periods; add overtime, bonuses and commissions.
2. Take off pre-tax deductions. 401(k) contributions and health premiums come off first — what is left is taxable wages.
3. Withhold the taxes. Federal income tax per the employee’s W-4, plus Social Security 6.2% and Medicare 1.45% (and the extra 0.9% on wages over $200,000).
4. Take off post-tax deductions. Roth contributions, garnishments and similar — the rest is net pay, which goes to the employee.
5. Deposit the taxes. Everything you withheld plus your employer share goes to the IRS through EFTPS — monthly or semiweekly, on schedule.
6. File the forms. Form 941 every quarter, Form 940 once a year, and W-2s to employees and the SSA by 31 January.

One-time setup before your first payday:

• Get an EIN from the IRS (free).
• Register for state withholding and unemployment tax accounts.
• Arrange workers’ compensation insurance.
• Open a business bank account dedicated to payroll.
• Choose a pay schedule — weekly, biweekly, semimonthly or monthly.
• Decide how you’ll run payroll: software, a provider, or by hand.

Worked example: one employee on $45,000

Take one employee earning $45,000 a year, with no pre-tax deductions and no state taxes shown. Here is what the federal payroll taxes for 2026 look like:

Line	2026 figure
Employee Social Security (6.2% × $45,000)	$2,790.00 — withheld from pay
Employee Medicare (1.45% × $45,000)	$652.50 — withheld from pay
Employee take-home before income tax	$41,557.50
Employer Social Security match (6.2%)	$2,790.00
Employer Medicare match (1.45%)	$652.50
Employer FUTA (0.6% × $7,000)	$42.00
Total employer payroll tax	$3,484.50
Total employer cost ($45,000 + $3,484.50)	$48,484.50

Two things to remember. Federal and state income tax withholding is the employee’s money, not yours — it never counts as an employer cost. And state unemployment tax sits on top of these federal figures; it varies by state, so check your state’s rate.

Payroll Taxes, Piece by Piece (2026)

FICA: Social Security and Medicare

The core payroll tax is FICA, totaling 7.65% each for employer and employee:

• Social Security: 6.2% each on wages up to the $184,500 wage base for 2026. Earnings above that escape Social Security tax for the rest of the year.
• Medicare: 1.45% each on all wages — no cap.
• Additional Medicare tax: 0.9% on wages above $200,000 — the employer withholding trigger; the liability threshold is $250,000 for joint filers. Employers must withhold it once wages cross $200,000, regardless of filing status, and there is no employer match on this slice.

Medicare tax rate (2026)

The medicare tax rate for 2026 is 2.9% combined — 1.45% from the employee and 1.45% from the employer — with no wage cap. Self-employed workers pay the full 2.9% themselves. Earnings above $200,000 ($250,000 for joint filers) attract an additional 0.9% Medicare tax, which employers must withhold once an employee’s wages cross $200,000.

FUTA: federal unemployment tax

Employers pay FUTA of 6% on the first $7,000 of each employee’s wages. Pay your state unemployment tax on time and you earn a credit of up to 5.4%, leaving an effective federal rate of just 0.6% — $42 per employee per year. Miss the state payment and the credit shrinks, which is a needlessly expensive mistake.

Federal income tax withholding

You also withhold federal income tax from each paycheck based on the employee’s Form W-4 and IRS withholding tables. This is not your money and never your tax — you are merely the conduit. Treat it with the seriousness it deserves (see the trust fund penalty below).

Anatomy of a Paycheck: A Walkthrough

Abstract tax rates become concrete fast when you follow one paycheck through the system. Take a salaried employee earning $65,000 a year, paid biweekly — $2,500 gross per pay period. Before a dollar reaches their bank account, the paycheck sheds layers in a fixed order:

• Pre-tax deductions first. A $150 401(k) contribution comes off the top, leaving $2,350 of taxable wages — pre-tax deductions shrink the base that income tax (and usually FICA) is calculated on.
• Federal income tax withholding per the employee’s W-4 — say roughly $280 for this paycheck.
• The employee’s FICA share: 6.2% Social Security ($145.70) plus 1.45% Medicare ($34.08) on the taxable wages.
• State income tax withholding and any post-tax deductions — Roth contributions, garnishments, union dues — come last.

The $2,500 gross lands at roughly $1,890 of net pay — $2,500 − $150 − $280 − $145.70 − $34.08 = $1,890.22 — and that is only the employee’s side of the ledger. The employer’s true cost runs higher: the matching 7.65% FICA (another ~$180), FUTA and state unemployment early in the year, workers’ comp and benefits.

Your Responsibilities as an Employer

Hiring employee number one triggers a compliance checklist:

• Get an EIN if you do not have one — free from the IRS, required for all payroll filings.
• Report new hires to your state’s new-hire registry, generally within 20 days.
• Deposit withheld taxes on schedule. New employers are usually monthly depositors; larger payrolls graduate to semiweekly based on a lookback period. Deposits go through EFTPS.
• File Form 941 quarterly to reconcile wages, withholding and FICA — due the last day of the month following each quarter.
• File Form 940 annually for FUTA, due 31 January (10 February if all deposits were timely).
• Furnish Forms W-2 to employees and file W-2/W-3 with the Social Security Administration by 2 February 2026 for the 2025 tax year (31 January falls on a Saturday).
• Handle state obligations: state unemployment insurance, state income tax withholding, and in many states, disability or paid family leave programs.

2026 payroll deadline calendar

Form 941 is due on the last day of the month following the end of each quarter. When that day falls on a weekend or public holiday, the deadline rolls to the next business day. Pin these dates somewhere you will actually see them:

Form	Quarter / period	Due date
Form 941	Q1 2026 (January–March)	30 April 2026
Form 941	Q2 2026 (April–June)	31 July 2026
Form 941	Q3 2026 (July–September)	2 November 2026*
Form 941	Q4 2026 (October–December)	1 February 2027*
Form 940 (FUTA)	Full year 2026	1 February 2027 (10 February if every deposit was timely)*
Forms W-2 and W-3	2026 tax year	1 February 2027*

*Shifted to the next business day — 31 October 2026 is a Saturday and 31 January 2027 is a Sunday. Made every deposit on time and in full? You earn an automatic 10-day extension on the 941 and 940 deadlines above. Deposits are the part the IRS grades harshly, though, so treat the earlier date as the real one.

Deposit schedules: monthly vs semiweekly

Withheld taxes are not yours to hold — the IRS sets your deposit schedule, and it depends on your size. New employers start as monthly depositors.

• Monthly: if you reported $50,000 or less in employment taxes during the lookback period (the 12 months ending the previous 30 June), deposit by the 15th of the following month.
• Semiweekly: above $50,000, paydays falling Wednesday to Friday mean depositing by the following Wednesday; Saturday to Tuesday paydays mean the following Friday.
• Next-day rule: accumulate $100,000 of tax liability in a single day and you must deposit by the next business day — then you stay semiweekly for the rest of the year.

Growing into semiweekly status without noticing is one of the most common — and most penalized — small-business mistakes.

Pay frequencies: weekly, biweekly, semimonthly or monthly

You can pay employees weekly (52 paychecks), biweekly (26 — the most common choice), semimonthly (24) or monthly (12).

• Weekly pleases hourly staff but doubles your runs compared with biweekly.
• Biweekly is the sweet spot for most small businesses.
• Monthly is simplest but brutal for employees’ budgeting.

One hard constraint: your state sets a minimum pay frequency — many require at least semimonthly or biweekly pay — so check state law before choosing.

Whatever you pick, keep it consistent: withholding tables, benefit deductions and deposit schedules all assume a stable rhythm.

New-hire reporting, done properly

Every new (and rehired) employee must be reported to your state’s new-hire directory, generally within 20 days of hire — some states demand it faster.

• What to report: the employee’s name, address, Social Security number and hire date, plus your business name, address and EIN.
• Why it exists: child-support enforcement rather than taxation — but the penalties for ignoring it are real.
• Multistate shortcut: employers in several states can designate one state for all filings.

Fold this into your onboarding checklist next to the W-4 and I-9 so no hire slips through.

EFTPS: how your deposits actually move

All federal payroll tax deposits travel through the Electronic Federal Tax Payment System (EFTPS) – the paper coupon books are long gone. Enroll free at EFTPS.gov, and do it before your first deposit deadline: your PIN arrives by post, which takes days.

Once enrolled you can schedule payments in advance, pay from any bank account, and get instant confirmation numbers — the paper trail that proves a deposit happened if the IRS ever says it did not.

Keep payroll records for four years

The IRS requires you to keep employment tax records for at least four years after the tax becomes due or is paid, whichever is later.

• What to keep: every W-4, pay stub, 941 and 940, W-2/W-3, tip report and record of deposits — organized and retrievable.
• How long: four years is the legal floor for payroll; many advisers suggest seven to match general tax-record habits.
• How to keep it: a shoebox of faded receipts will not survive an employment-tax audit — a backed-up digital archive will.

The single best investment a new employer can make is a decent payroll provider. The monthly cost is trivial next to the price of a single missed deposit penalty.

Remote and multi-state employees

Hire someone who works from another state and you have just taken on that state’s payroll rules too. As a rule of thumb, you withhold income tax and pay unemployment insurance where the employee works, not where your business is registered — and a single remote employee is enough to create that obligation in most states.

Hire in another state and you take on its payroll duties too. Concretely, that means:

• Register for withholding and unemployment accounts in every state where you have employees.
• Meet each state’s new-hire reporting deadline.
• Watch for local extras such as New York City’s local income tax or Philadelphia’s wage tax.
• Reciprocal agreements between a few neighboring states let the employee be taxed only in their home state — but those are the exception, not the rule.

Get multi-state payroll wrong and you can owe penalties in two states at once, which is one of the strongest arguments for a payroll provider that handles multi-state filings.

State payroll taxes: a note with examples

Federal payroll tax is only half the story. Every state runs its own unemployment insurance program, most levy state income tax withholding, and several add disability or paid-leave premiums on top. A few examples show how much it varies:

• California: state income tax withholding, plus State Disability Insurance (SDI) paid by the employee and Employment Training Tax paid by the employer.
• New York: state income tax withholding, plus New York City and Yonkers local taxes where applicable, and state disability coverage.
• New Jersey: unemployment, temporary disability and family leave insurance — with contributions coming from both the employer and the employee.
• Texas, Florida and Washington: no state income tax to withhold, but you still owe state unemployment insurance — and Washington adds paid family and medical leave premiums on top.

New employers start on a fixed state rate. In California, for example, a new employer pays 3.4% unemployment insurance on only the first $7,000 of each employee’s yearly wages (2026 figures from the California EDD).

State rates, wage bases and filing frequencies change often, so confirm the current figures with the state’s workforce or revenue agency before you run your first payroll there.

Self-Employment Tax in Depth

If you are self-employed – sole proprietor, partner, LLC member, freelancer – you pay 15.3% self-employment tax: the combined employer and employee shares of Social Security (12.4%) and Medicare (2.9%). Think of it as a self employed payroll of one: you are both the employer and the employee, so both halves land on you. Key mechanics:

• It applies to 92.35% of your net earnings (the math behind that figure gives you the equivalent of the employer’s deduction).
• It kicks in at just $400 of net earnings for the year.
• The Social Security portion stops at the $184,500 wage base for 2026; Medicare continues uncapped, plus the 0.9% additional tax above $200,000/$250,000.
• You calculate it on Schedule SE and — small mercy — deduct one-half of it as an adjustment to income.
• It is paid through your quarterly estimated payments, alongside your income tax.

Have both a job and a side business? The $184,500 Social Security wage base covers your W-2 wages and self-employment earnings combined, and W-2 wages count first — a high salary can use up most or all of the cap before Schedule SE. The 2.9% Medicare part has no cap.

A freelancer netting $80,000 owes roughly $11,300 in self-employment tax alone. That number is the reason S corporation elections and diligent expense tracking exist.

Schedule SE walkthrough: an $80,000 freelancer

Here is exactly how the “roughly $11,300” figure above is built, step by step, for a freelancer with $80,000 of net profit (from Schedule C) and no other earnings in 2026:

1. Reduce net profit to net earnings. Schedule SE taxes only 92.35% of net profit: $80,000 × 0.9235 = $73,880. The 7.65% haircut is the rough equivalent of the employer’s share that an employee never pays tax on.
2. Figure the Social Security portion. $73,880 sits well below the $184,500 wage base, so all of it counts: $73,880 × 12.4% = $9,161.12.
3. Figure the Medicare portion. No cap applies: $73,880 × 2.9% = $2,142.52. (The extra 0.9% Medicare tax only starts above $200,000 of earnings, so it does not apply here.)
4. Add them for the total. $9,161.12 + $2,142.52 = $11,303.64, reported as $11,304 — the “roughly $11,300” from the section above. This total flows onto your Form 1040 via Schedule 2.
5. Claim the one-half deduction. $11,303.64 ÷ 2 = $5,651.82 (reported as $5,652) is deductible as an adjustment to income on Schedule 1 — it lowers your income tax, though not the self-employment tax itself.

The $11,304 is collected through your quarterly estimated payments, which is why each installment has to cover both income tax and self-employment tax — not just income tax.

How to reduce your self-employment tax

You cannot dodge self-employment tax, but you can shrink the base it is charged on — and choose structures that reduce it. Three legitimate levers:

• Claim every deductible business expense. Ordinary, necessary costs on Schedule C lower net earnings — the 92.35% base SE tax is calculated on. Good expense tracking is the simplest SE tax cut there is.
• Consider an S corporation election. Once profits comfortably exceed a reasonable salary, electing S-corp status (see our LLC taxes guide) means only the salary faces payroll tax; remaining distributions escape SE tax — though not income tax.
• Max out retirement contributions — for income tax. The myth-buster: 401(k) and SEP IRA contributions cut your income tax bill but do not reduce self-employment tax itself. They are still valuable, just on a different line.

Separate again is the 20% pass-through (QBI) deduction: it cuts your income tax, not your self-employment tax.

Every tax write-off you claim lowers the profit this tax is charged on.

New for 2026: Tips and Overtime Deductions

Two brand-new deductions affect workers and the businesses that employ them, available for 2025–2028:

• No tax on tips: eligible workers can deduct up to $25,000 of qualified tips from taxable income, phasing out above $150,000 of modified adjusted gross income ($300,000 joint).
• No tax on overtime: eligible workers can deduct the premium half of overtime pay up to $12,500 ($25,000 for joint filers), phasing out above the same income thresholds.

For employers, the practical takeaway is reporting: tips and overtime must be properly tracked and reported on W-2s so employees can claim these deductions. If you run a restaurant, bar, salon or any business with hourly staff, make sure your payroll system captures the required breakdowns — your employees’ new deductions depend on your paperwork.

S Corporation Owners: Salary vs Distributions

S corp owners who work in the business must take a reasonable salary — subject to full payroll tax — and can take remaining profit as distributions, which escape payroll and self-employment tax (though not income tax). This is the same mechanic that makes the S election attractive for LLCs: every dollar shifted from salary to distribution saves 15.3%.

The IRS knows this, which is why “reasonable” is doing heavy lifting. Pay yourself what you would have to pay someone else to do your job. Owners who take token salaries on six-figure profits are a perennial audit target, and reclassified distributions come with back taxes, penalties and interest.

For every route side by side on one worked example, see how to pay yourself from an LLC.

Employee vs Contractor: Get the Classification Right

Whether a worker is an employee or an independent contractor decides the entire tax treatment: employees trigger withholding, FICA and unemployment tax, while contractors handle their own self-employment tax and receive a Form 1099-NEC instead of a W-2. From 2026, you only send a Form 1099-NEC when you paid a contractor $2,000 or more in the year — up from $600. The label you put in the contract does not decide it — the IRS applies a common-law test built on three groups of evidence:

• Behavioral control: do you direct when, where and how the work is done?
• Financial control: do you control how the worker is paid, reimburse expenses and provide the tools?
• Relationship of the parties: is the work ongoing and central to your business, with benefits and an indefinite arrangement?

The more control you keep, the more likely the worker is an employee. If you are unsure, you can ask the IRS for a determination with Form SS-8 — but expect to wait months for an answer, so most small businesses decide based on the test above and document their reasoning.

Getting it wrong is expensive: back payroll taxes for every misclassified worker, failure-to-file and failure-to-deposit penalties, interest — and workers themselves can report the wages on Form 8919, which tends to bring the IRS to your door. When in doubt, the safe default is employee status or professional advice before the first payment goes out.

Estimated Taxes and the Self-Employed

Self-employment tax is not withheld anywhere, so it rides along in your quarterly estimated payments. For 2026 the due dates are 15 April, 15 June, 15 September 2026 and 15 January 2027.

The safe harbor — 100% of last year’s total tax (110% for higher earners) or 90% of this year’s — protects you from underpayment penalties.

When estimating, remember to include both income tax and the 15.3% self-employment tax in your quarterly math; newcomers routinely estimate only the income tax half and get an ugly surprise.

The Penalties That Hurt

• Trust fund recovery penalty: withheld employee taxes are “trust fund” money — the IRS can assess 100% of the unpaid amount personally against responsible owners and officers. It is not dischargeable and not limited to the business.
• Failure to deposit: penalties of 2–15% depending on lateness, plus interest.
• Failure to file W-2s/941s: per-form and per-return penalties that compound quickly.

Payroll tax debt is the one tax problem that follows owners home. When cash is tight, the temptation is to “borrow” from withheld taxes — resist it absolutely.

Common Payroll and SE Tax Mistakes

• Misclassifying employees as contractors to dodge payroll tax — back taxes and penalties when caught.
• Missing deposit schedules, especially after growing into semiweekly status.
• Forgetting the additional 0.9% Medicare withholding once an employee crosses $200,000.
• Estimating income tax but not self-employment tax in quarterly payments.
• Setting an unreasonably low S corp salary.
• Ignoring state payroll taxes — unemployment insurance, disability, paid leave.

Frequently Asked Questions

What is the self-employment tax rate for 2026?

15.3% on 92.35% of net earnings: 12.4% for Social Security (up to the $184,500 wage base) plus 2.9% for Medicare (no cap). Earnings above $200,000 ($250,000 joint) also attract an additional 0.9% Medicare tax. It applies from $400 of net earnings.

Do I owe self-employment tax if I have an LLC?

By default, yes — LLC members generally pay self-employment tax on their share of business profit. If the LLC elects S corporation status, only the owner’s salary is subject to payroll tax; distributions are exempt from both.

What’s the difference between payroll tax and income tax?

Payroll taxes (FICA, FUTA) fund Social Security, Medicare and unemployment programs at flat rates; income tax funds general government operations at graduated rates. As an employer you handle both: withholding income tax and paying/collecting payroll taxes.

When are 2026 estimated tax payments due?

15 April 2026, 15 June 2026, 15 September 2026 and 15 January 2027. Include both income tax and self-employment tax in your quarterly calculations.

Do employers pay tax on tips in 2026?

Tips remain subject to payroll taxes as wages; the new “no tax on tips” provision is a deduction for the worker (up to $25,000), not an employer exemption. Employers must still withhold and pay their share — and must report tips properly so employees can claim the deduction.

What is the trust fund recovery penalty?

It lets the IRS assess 100% of unpaid withheld taxes personally against responsible persons — owners, officers, even bookkeepers with signature authority. Withheld taxes are deemed to be held in trust for the government, and “borrowing” them is treated severely.

How do I know whether I am a monthly or semiweekly depositor?

New employers start as monthly depositors. After your first year, the lookback period — the 12 months ending the previous 30 June — decides: $50,000 or less in reported employment taxes keeps you monthly, depositing by the 15th of the following month; more makes you semiweekly. A $100,000 single-day liability triggers a next-business-day deposit.

How often must I pay my employees?

Federal law sets no pay frequency — your state does, and most require at least semimonthly or biweekly paydays. Within that rule, pick weekly, biweekly, semimonthly or monthly and keep it consistent.

How long should I keep payroll records?

Keep employment tax records at least four years after the tax becomes due or is paid, whichever is later. W-4s, pay records, Forms 941/940 and W-2s, organized and backed up.

Can I deduct half of my self-employment tax?

Yes. One-half of your self-employment tax is deductible as an adjustment to income on your personal return — it reduces your income tax, though not the self-employment tax itself.

Is payroll tax flat or progressive?

Mostly flat. Social Security (6.2%) and Medicare (1.45%) apply at the same rate to every dollar of wages, though the $184,500 Social Security cap makes the system slightly regressive at the top — high earners stop paying that part while lower earners never do. Only federal income tax withholding is progressive, rising with pay.

How much do employers pay in payroll taxes?

About 7.65% of gross pay for the FICA match, plus roughly $42 per employee per year in FUTA and your state unemployment tax. The worked example above puts real numbers on it: a $45,000 salary costs $48,484.50 all in.

What are gross taxable wages?

Gross pay minus any pre-tax deductions — 401(k) contributions, health premiums and similar come off before tax is calculated. In this guide’s paycheck walkthrough, $2,500 of gross pay minus a $150 401(k) contribution leaves $2,350 of taxable wages, and every withholding is figured on that $2,350.
