Payroll Taxes: What You Owe, When You Owe It

Payroll Taxes: What You Owe, When You Owe It

Hiring employees comes with payroll tax obligations. Miss a deposit deadline or file the wrong form, and the IRS penalties add up fast. This guide covers every payroll tax you need to handle, how to calculate them, and when to pay.

The Payroll Taxes You Owe

Federal Income Tax Withholding

You must withhold federal income tax from each employee's wages based on their Form W-4. The amount depends on their filing status, number of allowances or adjustments, and any additional withholding they request.

Use IRS Publication 15-T (Federal Income Tax Withholding Methods) or payroll software to determine the correct withholding amount for each pay period.

How withholding is calculated: The IRS provides two methods -- the Wage Bracket Method (lookup tables based on pay period, filing status, and wage amount) and the Percentage Method (a formula-based approach). Payroll software automates this, but if you run payroll manually, Publication 15-T walks through both methods step by step.

FICA Taxes (Social Security and Medicare)

FICA is split equally between employer and employee:

Tax	Employee Share	Employer Share	Wage Base (2025)
Social Security	6.2%	6.2%	$176,100
Medicare	1.45%	1.45%	No limit
Additional Medicare	0.9%	None	Over $200,000
Total FICA (below wage base)	7.65%	7.65%

You withhold the employee's share from their pay and pay the employer's share out of your own funds. The Additional Medicare Tax of 0.9% applies only to employee wages exceeding $200,000 -- there is no employer match for this.

Example: An employee earns $4,000 in a biweekly pay period. You withhold $306 (7.65%) from their paycheck for FICA and pay an additional $306 from company funds as the employer match. Total FICA for that pay period: $612.

Federal Unemployment Tax (FUTA)

FUTA is an employer-only tax. The rate is 6.0% on the first $7,000 of each employee's annual wages. However, you receive a credit of up to 5.4% for state unemployment taxes paid on time, reducing the effective FUTA rate to 0.6%.

Annual FUTA cost per employee: $7,000 x 0.6% = $42 (assuming full state credit).

For most businesses, FUTA is a minimal cost. A company with 10 employees pays roughly $420 per year in FUTA taxes. However, if you are in a "credit reduction state" (a state that has not repaid its federal unemployment loan), the FUTA credit may be reduced, increasing your effective rate.

How Much Does It Cost to Have an Employee? Complete Tax Breakdown

Many business owners underestimate the true cost of employment taxes. Here is what you actually pay on top of salary for a single employee:

Employee Earning $50,000/year

Tax/Cost	Calculation	Annual Cost
Employer Social Security	6.2% x $50,000	$3,100
Employer Medicare	1.45% x $50,000	$725
FUTA (effective)	0.6% x $7,000	$42
State Unemployment (avg 2.7%)	2.7% x $7,000	$189
Workers' Comp (avg, varies by industry)	~1.5% x $50,000	$750
Total employer tax burden		$4,806
Percentage above salary		9.6%

Employee Earning $100,000/year

Tax/Cost	Calculation	Annual Cost
Employer Social Security	6.2% x $100,000	$6,200
Employer Medicare	1.45% x $100,000	$1,450
FUTA (effective)	0.6% x $7,000	$42
State Unemployment (avg 2.7%)	2.7% x $7,000	$189
Workers' Comp (avg)	~1.5% x $100,000	$1,500
Total employer tax burden		$9,381
Percentage above salary		9.4%

Employee Earning $200,000/year

Tax/Cost	Calculation	Annual Cost
Employer Social Security	6.2% x $176,100 (capped)	$10,918
Employer Medicare	1.45% x $200,000	$2,900
FUTA (effective)	0.6% x $7,000	$42
State Unemployment (avg 2.7%)	2.7% x $7,000	$189
Workers' Comp (avg)	~1.5% x $200,000	$3,000
Total employer tax burden		$17,049
Percentage above salary		8.5%

Budget rule of thumb: Add 9-12% on top of salary for employer payroll taxes and workers' compensation. This does not include benefits like health insurance or retirement contributions.

Deposit Schedules

The IRS assigns you a deposit schedule based on your total tax liability during a lookback period (the 12-month period ending June 30 of the prior year):

Monthly Depositor

If you reported $50,000 or less in total employment taxes during the lookback period, you deposit monthly. Taxes accumulated during a month are due by the 15th of the following month.

Semi-Weekly Depositor

If you reported more than $50,000 in employment taxes during the lookback period, you deposit semi-weekly:

• Wages paid Wednesday through Friday: deposit by the following Wednesday
• Wages paid Saturday through Tuesday: deposit by the following Friday

Next-Day Deposit Rule

If you accumulate $100,000 or more in employment taxes on any day during a deposit period, you must deposit by the next business day. This also moves you to a semi-weekly schedule for the remainder of the calendar year and the following year.

New Employers

If you are a new employer (no lookback period), you are a monthly depositor for the first calendar year. This gives you more time between pay dates and deposit due dates.

Deposit Schedule Summary

Deposit Type	Trigger	Due Date
Monthly	Lookback period liability under $50,000	15th of following month
Semi-weekly (Wed-Fri payroll)	Lookback period liability over $50,000	Following Wednesday
Semi-weekly (Sat-Tue payroll)	Lookback period liability over $50,000	Following Friday
Next-day	$100,000+ accumulated in one day	Next business day

How to Make Deposits

All federal payroll tax deposits must be made electronically using the Electronic Federal Tax Payment System (EFTPS). You cannot mail a check for payroll tax deposits. Enroll at eftps.gov if you have not already.

EFTPS enrollment takes 5-7 business days (you receive a PIN by mail). Do not wait until your first payroll to enroll. If you are hiring your first employee, enroll in EFTPS the same day you apply for your EIN.

Filing Requirements

Form 941 (Quarterly)

File Form 941 each quarter to report:

• Total wages paid
• Federal income tax withheld
• Social Security and Medicare taxes (employee and employer shares)
• Deposits made during the quarter

Due dates: April 30, July 31, October 31, January 31

If you deposited all taxes on time and in full, you get an extra 10 days to file.

Form 944 (Annual -- Small Employers)

If your annual payroll tax liability is $1,000 or less, the IRS may allow you to file Form 944 annually instead of Form 941 quarterly. The IRS notifies eligible employers. You cannot choose to file 944 without IRS approval.

Form 940 (Annual)

File Form 940 annually to report FUTA tax. Due January 31 for the previous year. If your total FUTA tax exceeds $500 for the year, you must make quarterly deposits.

Form W-2 (Annual)

Issue Form W-2 to each employee by January 31, reporting their total wages and tax withholdings for the prior year. File Copy A with the Social Security Administration.

Form W-3 (Annual)

File Form W-3 as a transmittal form with all W-2s sent to the Social Security Administration. Due January 31.

Employee vs. Independent Contractor: Getting Classification Right

Misclassifying employees as independent contractors is the single most common -- and most expensive -- payroll tax mistake. The IRS estimates that millions of workers are misclassified, and enforcement is a top priority.

The IRS Classification Test

The IRS uses three categories to determine worker classification:

Behavioral Control: Do you control what the worker does, when they do it, and how they do it? If yes, they are likely an employee.

Financial Control: Do you control the business aspects of the worker's job, including how they are paid, whether expenses are reimbursed, and who provides tools/supplies? If you control these, they are likely an employee.

Relationship Type: Are there written contracts, employee-type benefits (insurance, pension, vacation pay), and is the relationship expected to continue indefinitely? If yes, they are likely an employee.

Classification Comparison

Factor	Employee (W-2)	Contractor (1099)
You control when/where they work	Yes	No
You provide tools and equipment	Yes	No
They work for other clients	Typically no	Yes
You provide training	Yes	No
You provide benefits	Often	No
Relationship duration	Ongoing	Project-based
You withhold taxes	Yes	No
Your cost above their pay	9-12% (employer taxes)	0%

Penalties for Misclassification

If the IRS reclassifies your contractors as employees, you owe:

• 100% of the employer share of FICA taxes you should have withheld and matched
• The employee share of FICA you should have withheld (you can try to collect from the worker, but good luck)
• Federal income tax you should have withheld (estimated at 1.5% of wages as a proxy)
• Interest on all back taxes from the date they were originally due
• Penalties of 2-15% of the unpaid taxes

In cases of willful misclassification, penalties escalate further. Some states impose their own additional penalties and fines.

Penalties for Non-Compliance

Payroll tax penalties are among the harshest in the tax code:

• Late deposit penalty: 2% (1-5 days late), 5% (6-15 days late), 10% (16+ days late), 15% (if not deposited within 10 days of IRS notice)
• Late filing penalty: 5% of unpaid tax per month, up to 25%
• Trust fund recovery penalty: If you willfully fail to withhold and deposit employment taxes, the IRS can assess a penalty equal to 100% of the unpaid taxes against you personally -- even if your business is an LLC or corporation

The trust fund recovery penalty is personal. It pierces the corporate veil and holds responsible individuals liable. This includes business owners, officers, and anyone else with authority over financial decisions.

Late Deposit Penalty Schedule

Days Late	Penalty Rate	Example ($5,000 deposit)
1-5 days	2%	$100
6-15 days	5%	$250
16+ days	10%	$500
10+ days after IRS notice	15%	$750

The Trust Fund Recovery Penalty (TFRP) Explained

The TFRP deserves special attention because it is unlike any other tax penalty. "Trust fund" taxes are the taxes you withhold from employee paychecks (federal income tax and the employee share of FICA). The IRS considers these funds held in trust for the government -- they are not your money to use for other business expenses.

If you use withheld payroll taxes to pay other bills (rent, vendors, etc.) instead of depositing them with the IRS, that is considered willful failure. The IRS can assess the TFRP against:

• Business owners (including LLC members)
• Corporate officers (CEO, CFO, etc.)
• Anyone with authority to sign checks or direct payments
• Bookkeepers or accountants with control over funds

The TFRP cannot be discharged in bankruptcy. This makes it one of the most dangerous financial risks a small business owner can face.

Common Payroll Tax Mistakes

1. Missing Deposit Deadlines

The most common mistake for new employers. Set up automatic reminders or use a payroll service that handles deposits automatically. One late deposit triggers a 2-15% penalty -- and late deposits in multiple periods can trigger an IRS audit.

2. Using Payroll Tax Funds for Other Expenses

When cash is tight, some business owners "borrow" from withheld payroll taxes to cover other bills. This is the single most dangerous thing you can do. The trust fund recovery penalty will follow you personally, regardless of whether your business survives.

3. Not Adjusting Withholding When Employees Update W-4s

When an employee submits a new W-4, you must implement the changes by the start of the first payroll period ending on or after the 30th day after receiving the form. Continuing to use the old W-4 creates errors that compound over the year.

4. Forgetting State Payroll Obligations

Federal payroll taxes are only half the story. Every state has its own requirements for income tax withholding, unemployment insurance, and potentially disability insurance or paid family leave. Some cities (New York City, Philadelphia, etc.) impose additional local payroll taxes.

5. Incorrect Calculation of the Additional Medicare Tax

The 0.9% Additional Medicare Tax applies only to wages exceeding $200,000 for the year. However, you must begin withholding when an employee's wages exceed $200,000 from your company -- even if they have other income that would change the threshold. You do not consider their filing status for withholding purposes. The employee reconciles any over- or under-withholding on their personal return.

Payroll Setup Checklist

1. Obtain an Employer Identification Number (EIN) from the IRS (irs.gov -- instant online)
2. Register for EFTPS at eftps.gov (allow 5-7 days for PIN)
3. Collect Form W-4 from each employee before their first paycheck
4. Collect Form I-9 (Employment Eligibility Verification) within 3 days of hire
5. Register with your state for income tax withholding and unemployment insurance
6. Verify state new hire reporting requirements (required in all 50 states)
7. Set up a payroll system (software or service provider)
8. Determine your deposit schedule (monthly for new employers)
9. Calendar all filing deadlines (quarterly 941, annual 940, W-2, W-3)
10. Set up workers' compensation insurance (required in most states)

Should You Use a Payroll Service?

For most small businesses, the answer is yes. Payroll services handle calculations, deposits, and filings for a relatively small fee. The cost of a payroll mistake -- penalties, interest, and personal liability -- far exceeds the cost of outsourcing. If you have even one employee, invest in a payroll solution that handles federal and state tax compliance automatically.

Payroll Service Comparison

Service	Monthly Cost (1-10 employees)	Key Features
Gusto	$40 + $6/employee	Full-service, benefits, HR tools
QuickBooks Payroll	$45 + $6/employee	Integrates with QuickBooks
ADP Run	$59 + $4/employee	Scalable, strong compliance
Paychex Flex	Custom pricing	Full-service, dedicated support
Square Payroll	$35 + $6/employee	Good for retail/restaurants
OnPay	$40 + $6/employee	Simple, all-inclusive
Wave Payroll	$20 + $6/employee	Budget option, limited features

What to look for: automatic tax calculations, automatic tax deposits (not just reminders), quarterly and annual filing included, W-2 and 1099 preparation, state tax compliance, and a tax penalty guarantee (the service pays any penalties caused by their errors).

DIY Payroll: When It Makes Sense

DIY payroll might work if you have only one employee (yourself, as an S corp owner-employee), your state has simple payroll requirements, and you are comfortable with tax calculations and EFTPS. Even then, the risk of a $100-$500 monthly payroll service is small compared to potential penalties. The time you spend on DIY payroll is almost certainly worth more than the service fee.

Payroll Tax Credits That Reduce Your Cost

Several federal tax credits can offset your payroll tax burden:

Work Opportunity Tax Credit (WOTC)

A credit of $1,200 to $9,600 per qualifying employee (depending on the target group and hours worked). Qualifying target groups include veterans, SNAP recipients, ex-felons, long-term unemployment recipients, and designated community residents. You must obtain certification (Form 8850) from your state workforce agency within 28 days of the employee's start date.

Employee Retention Credit (ERC)

While the ERC was primarily a COVID-era credit (2020-2021), businesses that were eligible but did not claim it can still file amended returns. The credit was worth up to $7,000 per employee per quarter in 2021. Consult with a CPA to determine if you are eligible for retroactive claims, and be cautious of aggressive ERC mills that over-promise.

Paid Family and Medical Leave Credit

Employers who provide paid family and medical leave to qualifying employees may be eligible for a credit of 12.5% to 25% of wages paid during leave periods. The credit applies to businesses with fewer than 50 employees and requires a written leave policy.

Small Business Health Insurance Credit

Small businesses with fewer than 25 full-time equivalent employees and average annual wages below $56,000 (indexed for inflation) that pay at least 50% of employee health insurance premiums can receive a credit of up to 50% of premiums paid.

Hiring Your First Employee: A Complete Tax Checklist

Many business owners delay hiring because the payroll tax requirements seem overwhelming. Here is the complete process broken down into manageable steps:

Before the hire:

1. Apply for an EIN at irs.gov (instant, free)
2. Register with your state for income tax withholding
3. Register with your state for unemployment insurance
4. Obtain workers' compensation insurance (required in most states)
5. Enroll in EFTPS at eftps.gov (allow 5-7 business days for PIN)
6. Choose a payroll system or service

At the time of hire: 7. Have the employee complete Form W-4 (federal withholding) 8. Complete Form I-9 (within 3 business days of start date) 9. Report the new hire to your state's new hire reporting agency (required in all 50 states, typically within 20 days)

Each pay period: 10. Calculate gross pay, withholdings, and net pay 11. Deposit withheld taxes according to your deposit schedule 12. Issue paystubs to employees

Quarterly: 13. File Form 941 by the end of the month following the quarter 14. File state withholding return 15. File state unemployment return

Annually: 16. Issue W-2s to employees by January 31 17. File W-3 with the Social Security Administration by January 31 18. File Form 940 (FUTA) by January 31 19. Reconcile annual payroll totals

This process becomes routine after the first quarter. A payroll service automates steps 10-18 entirely.
