Payroll Taxes 101: Everything Small Business Owners Must File

Last Updated: July 27, 2026

Payroll taxes for small businesses are not a single tax. They’re a set of federal, state, and sometimes local obligations that every employer must calculate, withhold, deposit, and file on a fixed schedule. Miss one deadline, and the IRS penalty clock starts immediately. Understand the system, though, and it becomes one of the most manageable parts of running your business.

If you’re still setting up payroll for the first time, start with FRIDAY’s guide on how to do payroll for a small business before working through the filing requirements here.

What Payroll Taxes Does a Small Business Owner Actually Owe?

As an employer, you’re responsible for two categories of payroll taxes: taxes you withhold from employee paychecks on behalf of the government, and taxes you pay directly on top of wages. Both employer and employee contribute to certain taxes, while others fall on the employer alone.

On FRIDAY, we regularly see first-time employers underestimate employer-side payroll taxes by 8 to 12 percent when building their first hiring budget. In most cases, the gap comes from forgetting employer FICA contributions, FUTA, and state unemployment taxes when forecasting labor costs. A business that budgets $50,000 for a new hire’s salary is actually committing closer to $54,000 to $56,000 once all employer tax contributions factor in.

For a deeper explanation of how each tax type works, see FRIDAY’s guide on what payroll tax is.

What Are the Four Types of Payroll Taxes?

Small businesses generally manage four categories of payroll tax: FICA, FUTA, SUTA, and federal income tax withholding. Some states and localities add a fifth layer through state income tax withholding or local payroll taxes. Each has its own rate, its own deposit schedule, and its own filing requirement, which is exactly why payroll tax compliance trips up so many first-time employers.

Federal Payroll Taxes: The Complete Breakdown

What Is FICA?

FICA stands for the Federal Insurance Contributions Act. It covers Social Security and Medicare taxes, and employee and employer split each evenly. Every business with W-2 employees must pay Social Security tax and Medicare tax every pay period without exception. The full rules governing FICA appear in IRS Publication 15, the Employer’s Tax Guide.

Social Security tax:

• Employee rate: 6.2% of taxable wages
• Employer rate: 6.2% of taxable wages
• 2026 wage base limit: $184,500 per employee per year
• Once an employee’s total wages exceed $184,500, Social Security tax stops for that employee for the rest of the calendar year

Medicare tax:

• Employee rate: 1.45% of taxable wages
• Employer rate: 1.45% of taxable wages
• No wage limit; applies to all employee earnings
• Additional Medicare Tax: 0.9% on employee wages exceeding $200,000 in a calendar year, withheld from the employee only, with no employer match on this portion

Combined, FICA totals 15.3% of taxable wages, and employer and employee each pay 7.65%. That employer share alone adds roughly 7.65% to your labor cost on every dollar of wages up to the Social Security wage base.

Here’s a worked example: Rosa works a biweekly pay period and earns $1,394 gross.

Rosa’s employer owes $106.64 out of pocket in addition to her gross pay. For a 10-person team at similar wages, employer contributions to Social Security and Medicare typically add $1,000 to $1,500 per month on top of gross payroll, a number worth building into your labor budget from the start.

What Is Federal Income Tax Withholding?

Federal income tax withholding isn’t a fixed rate. It varies based on each employee’s W-4, their filing status, pay frequency, and the IRS tax tables published in IRS Publication 15-T. Employers withhold income tax from each paycheck and remit it to the federal government on the employee’s behalf.

As the employer, you don’t pay federal income tax for your employees. You’re the collection mechanism. The withheld amount belongs to the employee’s individual tax liability, and employees reconcile it when they file their annual return.

Getting employee tax withholding right starts with a complete, current W-4. The most common errors small businesses make:

• Using a pre-2020 W-4 that relies on the old allowances system, which produces incorrect withholding amounts
• Failing to update withholding when an employee submits a new W-4 mid-year
• Applying the wrong pay frequency when using IRS tax tables to determine the correct rate

If an employee under-withholds because of an error on your end, correcting it involves amended payroll records and a Form 941-X. Getting it right the first time is significantly easier than fixing it later.

What Is FUTA?

FUTA stands for the Federal Unemployment Tax Act. It requires employers to fund unemployment benefits for workers who lose their jobs. Unlike FICA, employers pay FUTA entirely on their own; no amount comes out of employee paychecks.

• FUTA tax rate: 6% on the first $7,000 of each employee’s wages per year
• Most employers qualify for a 5.4% credit if they pay their state unemployment taxes on time, which reduces the effective rate to 0.6%
• Maximum FUTA cost per employee per year at the 0.6% effective rate: $42
• If your SUTA payments are late, or your state is a credit reduction state, the full 6% rate or a higher effective rate may apply

FUTA deposits are quarterly, but only once your cumulative liability exceeds $500. If your liability stays under $500 through the year, you can pay it with your annual Form 940 by February 1, 2027.

What Is Federal Income Tax Withholding on Supplemental Wages?

Bonuses, commissions, overtime pay above regular wages, and severance pay count as supplemental wages. Employers can choose between two withholding methods:

• Flat rate method: withhold 22% flat on the supplemental payment
• Aggregate method: add the supplemental wages to the employee’s regular wages for that pay period and withhold based on the combined amount using the standard IRS tax tables

The flat 22% rate is simpler for most small businesses and is the most commonly used method. For supplemental wages exceeding $1 million in a calendar year, the rate jumps to 37%.

State Payroll Taxes: SUTA and Beyond

What Is SUTA?

SUTA stands for the State Unemployment Tax Act. It funds unemployment benefits at the state level, and employers pay it entirely in most states. A few states, including Alaska, New Jersey, and Pennsylvania, also require employee contributions.

SUTA rates vary significantly by state and adjust over time based on experience rating, meaning your rate changes based on how many former employees have filed unemployment claims against your account. New employers typically start at a standard new-employer rate the state’s labor department sets.

For state-specific registration requirements before you begin paying SUTA, see FRIDAY’s employer registration by state guide.

Key SUTA facts every small business owner should know:

• Every state sets its own wage base limit. Unlike FUTA, which applies only to the first $7,000 of wages, state wage bases range from $7,000 in states like Arizona and Florida to over $60,000 in states like Washington
• You must register with your state’s unemployment agency before running your first payroll, not after
• SUTA is filed quarterly in most states, with reports and payments due the month after each quarter ends
• Paying state unemployment taxes on time matters beyond the state level too, since late SUTA payments reduce or eliminate your FUTA credit, directly increasing your federal unemployment tax cost
• States with no state income tax withholding: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. These states may still require SUTA registration and payments.

States with additional payroll requirements:

• California requires State Disability Insurance (SDI) contributions from employees
• New York employers may owe Metropolitan Commuter Transportation Mobility Tax (MCTMT) on top of state income tax withholding
• New Jersey requires contributions to family leave insurance and temporary disability insurance
• Hawaii, Rhode Island, and Washington also have state-mandated disability or paid family leave programs

One of the most common multi-state payroll mistakes FRIDAY sees is businesses assuming they can simply add a remote employee to payroll without new state registrations. In practice, adding even one employee in another state often triggers new withholding, unemployment insurance, and reporting obligations. Contact each state’s revenue and labor departments separately to confirm requirements before the first paycheck goes out.

Deposit Schedules: When Do You Actually Send the Money?

In payroll cleanup cases FRIDAY reviewed internally during 2025, late deposits turned out to be far more common than late filings. Many business owners filed Form 941 on time every quarter but missed EFTPS deposit deadlines throughout the quarter because they assumed filing and depositing were the same obligation. They aren’t, and penalties accumulate before the business ever submits the 941.

Filing a form and depositing employment taxes are two completely separate obligations. You can file Form 941 perfectly on time and still owe significant penalties if your deposits were late throughout the quarter.

The IRS assigns your deposit schedule based on your total payroll tax liability during a lookback period, covering the 12-month period ending June 30 of the prior year.

Monthly depositor:

• Applies if your total payroll tax liability during the lookback period was $50,000 or less
• Deposit due date: the 15th of the month following each payday
• Example: payroll runs in March, deposit is due April 15

Semi-weekly depositor:

• Applies if your total payroll tax liability during the lookback period exceeded $50,000
• Paydays on Wednesday, Thursday, or Friday: deposit due the following Wednesday
• Paydays on Saturday, Sunday, Monday, or Tuesday: deposit due the following Friday

New employers start as monthly depositors regardless of business size. The $100,000 next-day rule applies to both schedules: if your payroll tax liability reaches $100,000 or more on any single day during a deposit period, you must deposit it the next business day.

All federal payroll tax deposits go through EFTPS, the Electronic Federal Tax Payment System. Enroll before your first payroll run, since it takes five to seven business days to receive your PIN by mail. A check mailed to the IRS isn’t an acceptable substitute for an EFTPS deposit.

Federal Payroll Tax Forms: What to File and When

Form 941: Quarterly Payroll Tax Return

Form 941 is the primary quarterly filing for most small business employers. It reports total wages, federal income tax withholding, employee and employer shares of Social Security and Medicare taxes, adjustments for sick pay or tips, and credits claimed such as the small business health care tax credit.

2026 filing deadlines:

• Q1 (January through March): April 30
• Q2 (April through June): July 31
• Q3 (July through September): November 2, 2026 (shifted from October 31)
• Q4 (October through December): February 1, 2027 (shifted from January 31)

If you made all required deposits on time and in full, the IRS grants a 10-day extension automatically. Most employers with W-2 employees file Form 941. Exceptions include seasonal and agricultural employers, who may file Form 944 or Form 943 instead.

Form 940: Annual FUTA Return

Form 940 reconciles your federal unemployment tax for the full calendar year. You file it once a year, due February 1, 2027, for the 2026 tax year. If you deposited all FUTA taxes on time throughout the year, you have until February 10, 2027, to file.

Form 940 is separate from Form 941. Many first-time employers overlook it because it covers annual filings rather than quarterly ones.

W-2 and W-3

The W-2 reports each employee’s annual wages and taxes withheld. You must distribute W-2s to all employees and file copies with the Social Security Administration via SSA Business Services Online, both by February 1, 2027, for the 2026 tax year, using Form W-3 as the transmittal cover.

One often overlooked issue is employee address accuracy. Returned W-2s create filing delays and correction requests that require amended forms. Verify every employee’s mailing address during your Q4 payroll audit, before you generate W-2s.

Common W-2 errors that trigger IRS notices:

• Social Security numbers that don’t match SSA records
• Box amounts that don’t reconcile with quarterly 941 filings
• Missing employer state ID numbers in Box 15

1099-NEC: Contractor Payments

If you paid an independent contractor $2,000 or more during the calendar year, you must file a 1099-NEC and send a copy to the contractor by February 1, 2027, for 2026 payments. This threshold rose from $600 to $2,000 under the One Big Beautiful Bill Act, effective for payments made after December 31, 2025. If you’re still finalizing 2025 contractor payments, the older $600 threshold applies to those.

Before making any contractor payment, collect a completed W-9. Without one, IRS rules require you to withhold 24% of payments as backup withholding and remit it to the IRS. The 1099-NEC requirement doesn’t apply to corporations in most cases; confirm the contractor’s entity type on their W-9 before deciding whether to file.

How Does an LLC Pay Payroll Taxes?

How an LLC handles payroll taxes depends on how the IRS classifies it for tax purposes. If an LLC has W-2 employees, including an owner paid as an employee of an LLC taxed as an S-corp, standard FICA, FUTA, and withholding rules apply exactly as described above. If the LLC is a single-member entity or a partnership and the owner takes profit rather than a W-2 salary, that owner generally pays self-employment tax instead of standard payroll tax on their own earnings, a distinction covered below.

Payroll Tax Penalties: What They Cost and How to Avoid Them

The IRS penalty structure for payroll tax violations is steep and escalates quickly, which is one of the strongest reasons small business owners choose automated payroll systems over manual processing.

Failure to Deposit penalty:

On a $5,000 deposit that’s 20 days late, the penalty alone is $500. On a $20,000 deposit, it’s $2,000, on top of any interest that continues to accrue.

Failure to File penalty: 5% of unpaid tax per month the return is late, up to 25% of the total unpaid amount.

Trust Fund Recovery Penalty: This is the most serious penalty small business owners face. The federal government holds payroll taxes withheld from employee paychecks in trust. If you use those funds for anything else, including covering business expenses during a cash crunch, the unpaid trust fund tax becomes a personal liability. The Trust Fund Recovery Penalty equals 100% of the unpaid trust fund taxes, and bankruptcy can’t discharge it.

In practice, this penalty most commonly happens when a struggling business prioritizes vendor payments over depositing employment taxes. It’s one of the few tax penalties that pierces the corporate veil and attaches to individuals personally.

Recordkeeping Requirements

The IRS requires employers to keep employment tax records for at least four years after the tax is due or paid, whichever is later. The FLSA requires payroll records for at least three years.

One overlooked issue during IRS payroll audits is missing EFTPS confirmation records. Businesses often keep copies of filed forms but can’t prove they made deposits on time because they never saved the EFTPS payment confirmations. Keeping deposit confirmations alongside your quarterly 941 filings prevents unnecessary disputes and gives you a clean paper trail if the IRS ever questions your deposit history.

Payroll recordkeeping checklist, recommended for every pay period:

• Employee W-4 forms and any updates
• Timesheets and hours worked records
• Gross pay calculations and pay stubs showing net pay
• Tax deposit confirmations from EFTPS
• Copies of all filed 941, 940, W-2, W-3, and 1099 forms
• Any IRS correspondence

Why FRIDAY Makes Payroll Tax Compliance Simple

Knowing how to handle payroll taxes correctly is one thing. Executing it consistently across every pay period, every quarter, and every year-end without errors is another challenge entirely.

Based on internal onboarding reviews at FRIDAY, businesses with fewer than 15 employees typically reduce payroll admin time from several hours per cycle to under 30 minutes once payroll tax automation and EFTPS deposits are fully configured. Manual payroll users in the same team size range often spend several hours per cycle reconciling deposit schedules, confirming EFTPS submissions, and tracking quarterly filing deadlines. The gap widens further at year-end, when W-2 generation, Form 940 reconciliation, and state annual filings all land at once.

FRIDAY automates the calculation of FICA, FUTA, SUTA, and federal income tax withholding every pay period. It deposits employment taxes through EFTPS automatically based on your assigned schedule, files Form 941 each quarter, and generates W-2s at year-end directly from your payroll data. That reduces the risk of calculation errors and missed deadlines, including changes like the 2026 1099-NEC threshold shift, which FRIDAY already reflects without you having to track legislation yourself.

FAQs

What payroll taxes does a small business owner have to pay?

Small business employers pay the employer share of Social Security (6.2%), Medicare (1.45%), FUTA (0.6% on the first $7,000 per employee after the credit), and state unemployment insurance, which varies by state. These employer contributions come on top of employee wages, and employers don’t deduct them from employee paychecks.

What is the difference between Form 941 and Form 940?

Employers file Form 941 quarterly to report federal income tax withholding plus Social Security and Medicare taxes for both employees and employers. Form 940 covers the annual FUTA return, and employers file it once per year. Most small businesses file both as part of their quarterly and annual obligations.

How often do small businesses deposit payroll taxes?

Most new small businesses start as monthly depositors, meaning deposits are due by the 15th of the month following each payroll. Once your annual payroll tax liability exceeds $50,000, you move to a semi-weekly deposit schedule. The IRS notifies you of your schedule, but you’re responsible for knowing and following it.

What happens if a small business misses a payroll tax deposit?

The IRS charges a Failure to Deposit penalty starting at 2% for deposits one to five days late and reaching 15% for deposits still unpaid after an IRS notice. Interest accrues daily on the unpaid amount on top of the penalty, and repeated missed deposits can trigger an IRS audit of your payroll records.

Do I owe payroll taxes for independent contractors?

No. Independent contractors handle their own self-employment taxes. As the employer, you don’t withhold or pay FICA, FUTA, or state unemployment taxes on contractor payments. You do need to collect a W-9 before paying them and file a 1099-NEC if you pay them $2,000 or more in a calendar year.

What is the $400 rule for self-employed people?

Any self-employed person, including sole proprietors and most LLC owners, who earns net earnings of $400 or more from self-employment must pay self-employment tax, which they file via Schedule SE. This tax totals 15.3% of net earnings and covers the equivalent of both the employee and employer share of Social Security and Medicare, since a self-employed person effectively pays both sides.
