Payroll tax withholding is one of the first federal tax responsibilities a business takes on after hiring employees. 

Each payday, an employer may need to calculate federal income tax withholding, withhold Social Security and Medicare taxes from employee wages, add the employer’s matching share of FICA taxes, and account for other employment taxes such as FUTA and state unemployment taxes. 

The process has four separate stages: 

Calculate the taxes → withhold the employee portion → deposit the required taxes → report the amounts to the IRS 

These steps are connected, but they are not the same thing. 

For 2026, the IRS says employers must withhold Social Security tax at 6.2% and Medicare tax at 1.45% from covered employee wages, while also paying a matching 6.2% Social Security and 1.45% Medicare tax as the employer. The 2026 Social Security wage base is $184,500.  

Federal income-tax withholding is calculated differently. It depends on the employee’s wages, pay frequency, and information provided on Form W-4, using the IRS withholding methods and tables in Publication 15-T.  

What Payroll Taxes Does an Employer Handle? 

The term “payroll taxes” is used broadly, so it helps to separate the major categories. 

Federal income tax withholding 

This is the federal income tax you withhold from an employee’s wages and send to the IRS. 

The amount depends on the employee’s Form W-4 and the IRS withholding tables. It is generally an employee tax, meaning you withhold it from the employee’s pay rather than paying it as an additional employer expense.  

Social Security tax 

Social Security tax is part of FICA. 

For 2026: 

Employee share: 6.2% 

Employer share: 6.2% 

Combined rate: 12.4% 

The Social Security wage base for 2026 is $184,500, so wages above that annual limit are generally no longer subject to Social Security tax for that employee.  

Medicare tax 

For 2026: 

Employee share: 1.45% 

Employer share: 1.45% 

Combined rate: 2.9% 

Unlike Social Security, Medicare tax has no wage base limit.  

Additional Medicare Tax 

Employers must also withhold an additional 0.9% Medicare tax from an employee’s wages when the employee’s wages exceed $200,000 during the calendar year. 

Only the employee pays this additional 0.9%. There is no matching employer portion. Employers must begin withholding it in the pay period when the employee’s wages exceed $200,000 and continue withholding it for the rest of that calendar year.  

Federal unemployment tax 

FUTA is different. 

FUTA is generally paid by the employer and is not withheld from employee wages. 

The standard FUTA rate is 6% on the first $7,000 of wages per employee, before the applicable state unemployment tax credit. Employers can generally receive a credit of up to 5.4% when the requirements are met, producing an effective federal rate of 0.6%.  

FUTA is reported separately on Form 940. 

For a more detailed comparison of the federal payroll forms, see Accounts Confidant’s Form 940 vs. Form 941 vs. Form 944 guide. 

Employee Withholding vs. Employer Payroll Taxes 

The difference between employee tax withholding and employer payroll taxes is important when calculating the cost of payroll. 

The federal income tax withheld from the employee belongs economically to the employee’s tax obligation. Social Security and Medicare are shared between the employee and employer. FUTA is an employer tax.  

Why this distinction matters 

Suppose an employee earns $2,000. 

The employee’s paycheck may be reduced by: 

• Federal income tax 
• Social Security 
• Medicare 
• Other applicable withholding 

The employer also incurs its own payroll-tax costs, including the employer’s Social Security and Medicare matching amounts. 

So the employee’s net pay is not the same thing as the employer’s total payroll cost. 

An employer calculating labor costs should account for both. 

How to Calculate Payroll Taxes 

The first step is determining whether the worker is actually an employee. 

The IRS says businesses must correctly distinguish employees from independent contractors. If the worker is an employee, the employer generally must withhold federal income tax, Social Security, and Medicare taxes and pay the employer share of FICA and applicable unemployment taxes.  

Worker classification is based on the facts of the relationship, including behavioral control, financial control, and the relationship between the parties. Calling someone a “contractor” in an agreement does not by itself determine their federal tax status.  

Once the worker is classified as an employee, use the following process. 

Step 1: Determine gross wages 

Start with wages subject to payroll taxes. 

Depending on the employee’s compensation package, this can include: 

• Regular wages 
• Overtime 
• Bonuses 
• Commissions 
• Taxable fringe benefits 
• Tips 
• Certain noncash compensation 

Not every payment is treated exactly the same for every payroll tax, so the payroll system should apply the applicable rules rather than assuming every dollar is treated identically. 

Step 2: Collect the employee’s Form W-4 

Form W-4 provides the information the employer uses to calculate federal income-tax withholding. 

The IRS’s 2026 Form W-4 was updated for recent tax-law changes and includes a new exemption-from-withholding checkbox in Step 4(c). Employers should use the current IRS withholding procedures for the applicable W-4.  

For employees who need help estimating their withholding, the IRS also provides an online Tax Withholding Estimator.  

Step 3: Calculate federal income tax withholding 

Employers generally use Publication 15-T and the employee’s Form W-4 to calculate federal income-tax withholding. 

The 2026 publication provides both the Percentage Method and Wage Bracket Method, as well as tables for automated payroll systems.  

The calculation can depend on: 

• W-4 filing status 
• Pay frequency 
• Wage amount 
• Step 2 entries 
• Step 3 credits 
• Additional withholding in Step 4(c) 

This is why there is no universal percentage you can apply to every employee’s paycheck for federal income tax. 

Step 4: Calculate Social Security and Medicare 

For covered wages in 2026: 

Social Security: 6.2% employee + 6.2% employer 

Medicare: 1.45% employee + 1.45% employer 

The 2026 Social Security wage base is $184,500. Medicare has no wage base limit.  

Step 5: Check for Additional Medicare Tax 

Monitor each employee’s year-to-date wages. 

Once wages exceed $200,000 during the calendar year, begin withholding the additional 0.9% Medicare Tax from wages paid after the threshold is reached. 

This additional withholding is an employee tax. The employer does not match it.  

Step 6: Calculate employer-only payroll taxes 

FUTA and state unemployment taxes generally belong on the employer side rather than being deducted from an employee’s take-home pay. 

FUTA generally applies to the first $7,000 of FUTA wages per employee, subject to exclusions, credits, and state credit-reduction rules.  

State unemployment rules are separate and can vary significantly by state. 

2026 Payroll Tax Calculation Example 

Suppose an employee receives a $2,000 weekly paycheck and the entire $2,000 is subject to Social Security and Medicare taxes. 

Employee Social Security 

$2,000 × 6.2% = $124 

Employee Medicare 

$2,000 × 1.45% = $29 

Total employee FICA withholding 

$124 + $29 = $153 

So, before federal income tax and any other deductions, the employee’s paycheck would have $153 withheld for employee FICA. 

The employer also owes: 

$124 Social Security 

plus 

$29 Medicare 

for a matching employer FICA cost of $153. 

The employer therefore has: 

$306 of combined employee and employer FICA tax 

associated with that $2,000 payroll. 

Federal income-tax withholding cannot be calculated from the $2,000 figure alone because the employee’s Form W-4 and the applicable 2026 IRS withholding method are required.  

This example also does not include FUTA, state unemployment taxes, state income-tax withholding, local taxes, benefits, or other payroll deductions. 

How the Payroll Tax Deposit Schedule Works 

One of the most common payroll mistakes is assuming that payroll taxes are always paid quarterly because Form 941 is quarterly. 

They are not. 

For federal employment taxes reported on Form 941, the IRS generally uses monthly or semiweekly deposit schedules, with a special $2,500 rule and a $100,000 next-day rule.  

The $2,500 rule 

If your Form 941 tax liability for the current quarter or prior quarter is less than $2,500, and you did not trigger the $100,000 next-day rule, you may generally pay the amount with a timely filed Form 941 instead of making deposits during the quarter.  

This is an important exception. 

It does not create a universal quarterly deposit schedule for all employers. 

Monthly deposit schedule 

For 2026, a Form 941 employer is generally a monthly schedule depositor when the applicable lookback-period taxes were $50,000 or less. 

Monthly depositors generally deposit employment taxes for wages paid during a month by the 15th day of the following month.  

For example: 

January payroll → deposit generally due February 15 

If the due date falls on a weekend or applicable legal holiday, the deposit generally moves to the next business day.  

Semiweekly deposit schedule 

A Form 941 employer whose lookback-period taxes were more than $50,000 is generally a semiweekly schedule depositor. 

For wages paid: 

Wednesday, Thursday, or Friday → deposit by the following Wednesday 

Saturday, Sunday, Monday, or Tuesday → deposit by the following Friday 

$100,000 next-day rule 

Regardless of whether you normally deposit monthly or semiweekly, accumulating $100,000 or more in employment taxes during a deposit period triggers the next-day deposit rule. 

The tax must generally be deposited by the next business day. A monthly depositor that triggers this rule also becomes a semiweekly depositor for the rest of the current year and the following calendar year.  

This is why a business should not determine its deposit schedule once and forget about it. 

The schedule can change when payroll tax liability changes. 

How Must Federal Payroll Taxes Be Deposited? 

Federal tax deposits generally must be made by electronic funds transfer. 

The IRS identifies several electronic options, including: 

• EFTPS 
• IRS Business Tax Account 
• IRS Direct Pay for businesses 
• Qualified financial institutions or authorized third parties 

EFTPS is a free service provided by the U.S. Department of the Treasury. For an electronic deposit to be timely through the applicable systems, the IRS says it generally needs to be initiated by 8 p.m. Eastern Time on the day before the due date.  

A business should not treat a check mailed to the IRS as equivalent to a required federal tax deposit. 

Is Filing Form 941 the Same as Paying Payroll Taxes? 

No, Form 941 is the quarterly reporting return. 

Payroll tax deposits are the payments made during the quarter under the applicable deposit schedule. 

The IRS generally requires Form 941 for each calendar quarter: 

When a deadline falls on a weekend or legal holiday, the next business day applies. For 2026, October 31, 2026 is a Saturday, so the Q3 deadline moves to November 2, 2026. January 31, 2027 is a Sunday, so the Q4 deadline moves to February 1, 2027.  

Employers that timely deposited all taxes in full can generally receive an additional 10 calendar days to file Form 941.  

What if the business files Form 944? 

Certain small employers are instead required or permitted by the IRS to file Form 944 annually. 

The IRS must generally notify the employer to use Form 944; the employer should not simply choose it because payroll taxes are low. 

Accounts Confidant’s IRS Form 944 guide explains the annual filing rules and the distinction between Form 941 and Form 944. 

How Does FUTA Fit Into Payroll Taxes? 

FUTA is part of the employer’s payroll-tax responsibility, but it follows a separate reporting and deposit process. 

FUTA: 

• Is generally paid entirely by the employer 
• Is not withheld from employee wages 
• Generally applies to the first $7,000 of FUTA wages per employee 
• Is reported on Form 940 

The standard federal FUTA rate is 6%, but eligible employers can generally receive up to a 5.4% credit for qualifying state unemployment tax payments.  

FUTA deposits are generally required when the accumulated FUTA tax liability reaches the applicable threshold, with a $500 quarterly threshold determining whether a deposit is due.  

This is another reason not to lump every payroll tax into the same deposit calendar. 

What About State and Local Payroll Taxes? 

Federal rules are only one layer of payroll compliance. 

Depending on where the business operates and where employees work, a business may also need to handle: 

• State income-tax withholding 
• State unemployment insurance 
• Local income taxes 
• Local payroll taxes 
• Paid-leave programs 
• Other state-specific employment taxes 

The rules vary by jurisdiction. 

A remote employee can create additional complexity because the employee’s work location can affect state withholding, unemployment, registration, and other obligations. 

For example, Pennsylvania has state income-tax withholding and may also involve local earned-income-tax requirements depending on the employee’s residence and work location.

A business with employees in multiple states should therefore maintain a separate state-compliance checklist rather than assuming its federal payroll setup automatically covers state requirements. 

What Payroll Records Should Employers Keep? 

Payroll records should be detailed enough to support: 

• Wages paid 
• Taxes withheld 
• Employer payroll taxes 
• Tax deposits 
• Tax returns 
• Year-end W-2 information 

Useful records include: 

• Employee Forms W-4 
• Payroll registers 
• Pay-date records 
• Gross and net wages 
• Federal withholding calculations 
• Social Security and Medicare calculations 
• Deposit confirmations 
• Forms 941 
• Form 940 
• Form 944, if applicable 
• Forms W-2 and W-3 
• State payroll records 
• Local tax records 
• Employee classification documentation 

The IRS generally requires employers to retain employment-tax records for at least four years.  

Keep a record of every deposit 

Do not rely on the payroll software’s transaction history alone. 

Keep the actual electronic payment confirmation and make sure the payment is associated with: 

• Correct EIN 
• Correct tax period 
• Correct amount 
• Correct federal tax type 

This becomes particularly important when reconciling Form 941. 

Common Payroll Withholding Mistakes 

Using outdated federal withholding tables 

Federal withholding procedures can change. 

For 2026, employers should use the current Publication 15-T methods and tables.  

Treating every employee as if the W-4 were identical 

Federal income-tax withholding depends on each employee’s W-4 information. 

Forgetting the employer FICA match 

The employee’s Social Security and Medicare withholding is only half the FICA calculation. 

The employer generally owes a matching amount. 

Missing the Social Security wage base 

For 2026, the Social Security wage base is $184,500. Medicare continues without a wage base limit.  

Forgetting Additional Medicare Tax 

The employer must begin withholding the additional 0.9% once an employee’s wages exceed $200,000 in the calendar year.  

Withholding federal income tax from an independent contractor 

Worker classification must be established before deciding whether employee payroll withholding applies.  

Confusing deposits with Form 941 

A company can deposit payroll taxes correctly and still file an incorrect Form 941 if the return does not agree with the payroll records. 

Blindly accepting payroll-system calculations 

Software is useful, but an employer still needs to review payroll reports, tax liabilities, and deposit confirmations. 

Payroll Tax Penalties 

Missing a payroll deposit can be expensive. 

The IRS currently applies Failure to Deposit penalties based on how late the deposit is: 

These percentages apply to the unpaid deposit amount under the applicable penalty rules. 

Trust Fund Recovery Penalty 

The stakes can be higher when an employer fails to pay trust fund taxes. 

Employee federal income-tax withholding and the employee share of Social Security and Medicare taxes are generally considered trust-fund taxes because the employer holds these amounts on behalf of employees. 

The IRS can assess the Trust Fund Recovery Penalty against responsible persons who willfully fail to collect, account for, or pay over those taxes. The penalty can equal 100% of the unpaid trust-fund tax.  

This is why payroll withholdings should not be treated like ordinary operating cash. 

Can an Employer Use Withheld Payroll Taxes to Pay Business Expenses? 

No, Employee payroll withholdings are held for payment to the government. 

Using withheld taxes as working capital can leave the business unable to satisfy its federal tax obligations and can expose responsible persons to the Trust Fund Recovery Penalty when the applicable requirements are met.  

A useful internal control is to maintain a separate payroll-tax tracking process so management can see: 

Employee withholding liability + employer payroll-tax liability + deposits made = remaining payroll-tax obligation 

What If a Payroll Provider Makes a Mistake? 

Using a payroll provider can reduce manual work, but it does not mean the employer should stop reviewing payroll. 

The IRS generally expects employers to ensure that returns are filed and employment taxes are deposited properly. 

If a provider makes an error: 

• Identify the affected pay periods. 
• Compare payroll reports with bank transactions. 
• Confirm the deposits actually reached the IRS. 
• Check the affected Form 941 or other return. 
• Correct payroll records. 
• File any required corrected return. 
• Address penalties or interest if they were assessed. 

The IRS provides procedures for correcting previously filed employment-tax returns, including Form 941-X for corrections to Form 941.  

Do not assume that a payroll provider’s internal record proves the IRS received the payment. 

A Practical Payroll Tax Compliance Checklist 

Before each payroll: 

• Employee classification is correct 
• Current Form W-4 is on file 
• Gross wages are accurate 
• Taxable benefits are reviewed 
• Federal income tax is calculated using current IRS procedures 
• Social Security tax is calculated correctly 
• Medicare tax is calculated correctly 
• Additional Medicare Tax is checked 
• State/local withholding is reviewed 

After payroll: 

• Employee net pay is correct 
• Employer FICA is recorded 
• FUTA liability is tracked 
• State unemployment tax is recorded 
• Payroll liabilities reconcile 

Before each federal deposit: 

• Correct deposit schedule confirmed 
• Deposit amount matches payroll liability 
• Required deposit date confirmed 
• Payment submitted electronically 
• Confirmation saved 

Quarterly: 

• Form 941 reconciled to payroll records 
• Deposits reconcile to Form 941 
• Schedule B completed when required 
• State returns completed 
• Payroll liability accounts reviewed 

Year-end: 

• Forms W-2 and W-3 reconciled 
• Form 940 completed when required 
• Payroll records retained 
• Final payroll reports archived 

When Payroll Processing Help Makes Sense 

Payroll becomes more difficult when the business has multiple employees, several pay schedules, multiple states, bonuses, commissions, remote employees, or frequent changes to compensation. 

In those situations, the recurring work is not simply “running payroll.” 

It includes: 

• Collecting payroll data 
• Calculating wages 
• Applying withholding rules 
• Recording employer taxes 
• Monitoring deposit deadlines 
• Filing payroll returns 
• Reconciling payroll liabilities 
• Preparing year-end reports 

Accounts Confidant’s Payroll Processing Services cover paycheck creation, direct-deposit processing, employee-record maintenance, payroll-tax compliance, and payroll reporting. 

Payroll also needs to connect with the rest of the accounting system. The payroll liability recorded in the books should reconcile with deposits and filed returns. 

Accounts Confidant’s Bank Reconciliation Services can be linked here for businesses that need payroll-related payments and other bank activity reconciled with their accounting records. 

Final Takeaway 

Payroll tax withholding is not one calculation and not one payment. 

An employer has to manage several connected responsibilities: 

Classify workers correctly → collect Form W-4 information → calculate withholding → withhold employee taxes → calculate employer taxes → deposit federal taxes on schedule → file required returns → reconcile payroll records 

For 2026, the most important federal numbers include: 

6.2% employee Social Security tax 

6.2% employer Social Security tax 

1.45% employee Medicare tax 

1.45% employer Medicare tax 

$184,500 Social Security wage base 

0.9% Additional Medicare Tax above $200,000 of employee wages 

6% FUTA rate on the first $7,000 of FUTA wages before applicable credit 

The most common payroll mistake is not necessarily a wrong percentage. It is confusing one responsibility with another—such as treating Form 941 as the payment itself, assuming every employer has the same deposit schedule, or treating employee withholding as business cash. 

Businesses should also keep payroll records organized and reconcile payroll liabilities regularly. The IRS requires employers to retain employment-tax records for at least four years.  

For businesses that want help with payroll processing, payroll-tax compliance, reconciliations, and payroll reporting, Accounts Confidant provides payroll processing and accounting support.
