The IRS assessed over $7 billion in civil penalties for employment taxes in a single recent fiscal year. These penalties rarely stem from fraud, but from misinterpreting the exact rules you'll face on the EA Part 2 exam. The costliest error isn't forgetting a rate; it's misapplying a wage base limit or misunderstanding a single withholding threshold that separates a pass from a fail.
Payroll taxes on the EA exam test an employer's duty to withhold, remit, and report FICA (Social Security & Medicare) and FUTA (unemployment) taxes. Mastery requires calculating liabilities based on specific wage bases, applying correct rates, and meeting strict deposit and filing deadlines for forms like 941 and 940.

What Payroll Tax Rules Does the EA Exam Test?
The EA Part 2 exam tests your ability to function as a tax professional advising a business on its payroll obligations. This means you must master the calculation, deposit, and reporting of federal employment taxes. You will be tested on the specific rules for FICA, which funds Social Security and Medicare, and FUTA, which funds the federal unemployment system.
Examiners expect you to move beyond simple memorization. Questions are designed to test your judgment in applying these rules. You'll see scenarios involving multiple employees with different wage levels, requiring you to correctly apply the annual wage base limits. They will test your knowledge of filing deadlines for Form 941 (quarterly) and Form 940 (annual), including common extensions. A deep understanding of these rules is critical, as Enrolled Agents are the frontline advisors for businesses navigating these requirements under the standards of Treasury Circular 230.

The most common mistakes candidates make involve simple, avoidable errors. They confuse the employer and employee portions of FICA, misapply the Social Security wage base to Medicare, or use the wrong FUTA tax rate by forgetting the state tax credit. These are precisely the traps the exam sets. To see where you stand, you can try VoraPrep's free EA practice questions and identify your weak spots early.
FICA vs. FUTA: The Core Rules You Must Know
To pass, you need a precise understanding of who pays what, how much, and when. The entire system is built on two pillars: FICA and FUTA.
FICA (Social Security & Medicare)
FICA tax is a shared burden between the employer and the employee. For 2025, the rates are fixed and must be committed to memory.
- Social Security: The rate is 6.2% for both the employer and the employee. This tax applies only to wages up to the annual Social Security wage base, which is $168,600 for 2025. Once an employee's wages for the year exceed this amount, no more Social Security tax is withheld or paid.
- Medicare: The rate is 1.45% for both the employer and the employee. Crucially, there is no wage base limit for Medicare; it applies to all of an employee's wages.
FUTA (Federal Unemployment Tax)
FUTA tax is an employer-only tax. The employee pays nothing.
- FUTA Rate & Wage Base: The official FUTA tax rate is 6.0% on the first $7,000 of wages paid to each employee during the year (IRC §3301).
- The State Credit Trap: In practice, employers almost never pay the full 6.0%. They receive a credit of up to 5.4% for paying their state unemployment taxes (SUTA) on time. This reduces the effective federal FUTA rate to 0.6% (6.0% - 5.4%). The exam will almost always assume you know to use this net rate.
Here is a simple breakdown:
| Feature | FICA Taxes | FUTA Tax |
|---|---|---|
| Who Pays? | Employer AND Employee (shared) | Employer ONLY |
| 2025 Wage Base | $168,600 (Social Security only) | $7,000 per employee |
| Tax Rates | SS: 6.2% each. Medicare: 1.45% each. | 6.0% (gross), 0.6% (net, typical) |
| Key Form | Form 941 (Quarterly) | Form 940 (Annual) |
The $200,000 Withholding Trap: Additional Medicare Tax
Here is a rule that trips up many candidates. An Additional Medicare Tax of 0.9% applies to employee wages above certain thresholds ($200,000 for Single, $250,000 for MFJ).
This tax is paid only by the employee. The employer does not match it.
However, the employer's responsibility for withholding this tax is tested differently. The employer must begin withholding the 0.9% tax as soon as an employee's wages for the year exceed $200,000, regardless of the employee's filing status. The employer isn't expected to know if the employee is single or married; they have a single, clear threshold to follow for withholding purposes.
Worked Example: A Realistic 2025 Payroll Calculation
Let's walk through a scenario you might see on the exam for tax year 2025.
Scenario: Apex Solutions Inc. has three employees in 2025:- David: Earned $80,000 in wages.
- Maria: Earned $175,000 in wages.
- Kevin: Earned $6,500 in wages.
Apex is in a state with no FUTA credit reduction and paid all its state unemployment taxes on time. We will calculate the employer's total 2025 federal payroll tax liability.

Step-by-Step Solution: Part 1: Calculate Employer's FICA Share- Social Security (Employer Share - 6.2% on wages up to $168,600):
- David: $80,000 * 0.062 = $4,960.00
- Maria: $168,600 (the wage base limit) * 0.062 = $10,453.20
- Kevin: $6,500 * 0.062 = $403.00
- Total Employer Social Security: $4,960.00 + $10,453.20 + $403.00 = $15,816.20
- Medicare (Employer Share - 1.45% on all wages):
- David: $80,000 * 0.0145 = $1,160.00
- Maria: $175,000 * 0.0145 = $2,537.50
- Kevin: $6,500 * 0.0145 = $94.25
- Total Employer Medicare: $1,160.00 + $2,537.50 + $94.25 = $3,791.75
- Total Employer FICA: $15,816.20 (SS) + $3,791.75 (Medicare) = $19,607.95
---
Part 2: Calculate Employer's FUTA Tax- FUTA Wage Base: The first $7,000 of wages for each employee.
- Net FUTA Rate: 0.6% (6.0% gross rate - 5.4% state credit).
- David: $7,000 (at wage base limit) * 0.006 = $42.00
- Maria: $7,000 (at wage base limit) * 0.006 = $42.00
- Kevin: $6,500 (wages are below the limit) * 0.006 = $39.00
- Total Employer FUTA: $42.00 + $42.00 + $39.00 = $123.00
---
Final Answer:- Apex Solutions Inc.'s Total 2025 Federal Payroll Tax Liability (Employer Share):
$19,607.95 (Employer FICA) + $123.00 (Employer FUTA) = $19,730.95

Calculate Your Required EA Study Hours
See exactly how many hours you need across SEE 1, 2, and 3 based on your experience and target test window.
The most common mistake is applying the Social Security tax to Maria's full $175,000 salary. This would incorrectly calculate her portion as $175,000 * 0.062 = $10,850, inflating the total tax. The examiner is testing whether you know the $168,600 limit for 2025 and that you apply it on a per-employee basis.
Another frequent error is using the gross FUTA rate of 6.0%. This would make the FUTA liability $1,230 ($420 + $420 + $390), ten times the correct amount. You must remember to apply the 5.4% state credit to arrive at the 0.6% net rate. VoraPrep's adaptive learning engine is designed to drill you on these specific traps until they become second nature. Our 3,000+ practice questions include detailed explanations that show you not just the right answer, but why the wrong answers are tempting.
Key Filing Deadlines and Forms
Correctly calculating the tax is only half the battle. You must also know the key forms and their deadlines.
- Form 941, Employer's Quarterly Federal Tax Return: Reports income taxes, Social Security tax, and Medicare tax withheld from employee's paychecks, plus the employer's share of FICA. It is filed quarterly, due by April 30, July 31, October 31, and January 31.
- Form 940, Employer's Annual Federal Unemployment (FUTA) Tax Return: Reports the employer's FUTA liability. It is filed annually, due by January 31. Exam Nuance: If you deposited all FUTA tax when it was due, you have until February 10 to file the form.
- Form W-2, Wage and Tax Statement: Must be furnished to employees and filed with the Social Security Administration (along with Form W-3) by January 31.
- Form 1099-NEC, Nonemployee Compensation: Used to report payments of $600 or more to independent contractors. Must be furnished to contractors and filed with the IRS by January 31.
How to Approach Payroll Questions on Exam Day
When a payroll question appears, take a breath and follow a process.
First, identify what the question is asking for: employer's share, employee's withholding, or total tax. Second, scan for the key data points: wages for each employee, the tax year (to confirm the SS wage base), and any special conditions like a FUTA credit reduction.
For calculation questions, write out the steps. Don't do it all in your head.
- Calculate Social Security for each employee, stopping at the $168,600 wage base.
- Calculate Medicare for each employee on their full wages.
- Calculate FUTA for each employee, stopping at the $7,000 wage base and using the 0.6% net rate.
- Sum the totals based on what the question demands.
This structured approach prevents careless errors under pressure. Understanding the consequences of non-compliance, such as the Trust Fund Recovery Penalty, reinforces why the IRS tests these details so rigorously.
Frequently asked questions
How many payroll tax questions are on the EA exam?
The IRS does not release an exact count, but payroll taxes are a core part of the SEE Part 2 blueprint, consistently making up a significant portion of the Business Taxation section. Expect to see several questions testing both calculations and rules.
What is the difference between FICA and SE tax?
FICA tax applies to employees and is split between the employee and employer (totaling 15.3%). Self-Employment (SE) tax applies to independent contractors and sole proprietors. The SE tax rate is 15.3% on 92.35% of net self-employment earnings, effectively covering both the "employee" and "employer" portions.
How do I know if an employer is a monthly or semi-weekly depositor?
An employer's deposit schedule is based on a lookback period. If the employer reported more than $50,000 in employment taxes during the lookback period (typically the four quarters ending June 30 of the prior year), they are a semi-weekly depositor. Otherwise, they are a monthly depositor.
What happens if a state is a FUTA credit reduction state?
If a state has outstanding federal unemployment loans, the IRS reduces the 5.4% SUTA credit available to employers in that state. This increases the effective federal FUTA rate. For the exam, the question will explicitly state if a credit reduction applies and by how much.
