Do you ever stare at a pay stub and wonder which line items are truly the employer’s responsibility and which are just the employee’s share?
On the flip side, it’s a rabbit‑hole that trips up small‑biz owners, freelancers who hire help, and even HR pros who haven’t brushed up on the rules in a few years. The short version is: not every tax that shows up on a paycheck is the company’s burden.
And yeah — that's actually more nuanced than it sounds.
Below, I’ll walk through what counts as an employer payroll tax, why it matters, the common mix‑ups, and—most importantly—the “except” part: the taxes that don’t belong on the employer’s balance sheet Simple as that..
What Is an Employer Payroll Tax?
When we talk about employer payroll taxes we’re really talking about the taxes a business must remit to federal, state, or local authorities because it paid wages. Think of it as the cost of hiring someone, on top of the salary you agree to It's one of those things that adds up..
In practice, an employer payroll tax is any tax that the employer calculates, withholds, and then sends to the government on behalf of (or for) its employees. The employer may also have to add its own matching portion Not complicated — just consistent..
The Core Trio
- Federal Insurance Contributions Act (FICA) – This bundles Social Security (6.2 % of wages) and Medicare (1.45 %). The employer pays a matching 7.65 % on top of the employee’s share.
- Federal Unemployment Tax Act (FUTA) – A flat 6 % on the first $7,000 of each employee’s wages, though most firms get a credit that drops the effective rate to about 0.6 %.
- State Unemployment Tax Act (SUTA) – Varies wildly by state, but it’s the state’s version of FUTA, also paid solely by the employer.
Those three are the backbone of “employer payroll taxes.” Anything else that shows up on a paycheck is either an employee‑only deduction or a tax the employee is responsible for filing themselves Surprisingly effective..
Why It Matters / Why People Care
If you’re a startup founder juggling cash flow, a mis‑classification can eat into your runway faster than you expect.
- Budgeting: Knowing the exact employer tax rate lets you price projects accurately. Forgetting the 7.65 % FICA match? Your profit margin shrinks before you even see a line item.
- Compliance: The IRS and state agencies don’t look kindly on late or under‑paid payroll taxes. Penalties can stack up quickly—think 10 % of the unpaid tax per month, plus interest.
- Employee Trust: When you consistently remit the correct amounts, you avoid awkward “my paycheck looks off” conversations. That keeps morale up and turnover down.
On the flip side, over‑paying taxes you don’t owe (like treating an employee’s health insurance premium as a payroll tax) ties up cash that could be used for growth. So separating the “yes” from the “except” isn’t just academic—it’s a real‑world cash‑flow decision Turns out it matters..
How It Works
Below is a step‑by‑step rundown of the employer payroll tax process, from wage calculation to filing. I’ll sprinkle in the “except” items as we go.
1. Calculate Gross Wages
Start with the employee’s agreed‑upon salary or hourly rate, then add any taxable bonuses, commissions, or overtime. This is your gross wage—the base for all subsequent tax calculations.
2. Apply Employee Withholdings
From that gross amount you subtract:
- Employee’s share of Social Security (6.2 %)
- Employee’s share of Medicare (1.45 %)
- Federal income tax (based on the W‑4)
- Any state income tax, local taxes, or pre‑tax deductions (like 401(k) contributions)
Important: Those employee withholdings are not employer payroll taxes. They’re the employee’s own tax obligations that the employer merely collects and forwards Still holds up..
3. Compute Employer Matching Taxes
Now you add the employer side:
- Social Security match – another 6.2 %
- Medicare match – another 1.45 %
- FUTA – 0.6 % (after credit) on the first $7,000 per employee
- SUTA – rate varies; often between 1 % and 5 % on a wage base that also caps at a state‑specific limit
These four line items are the core employer payroll taxes you must remit.
4. File Quarterly and Annual Returns
- Form 941 – quarterly federal payroll tax return (covers FICA and income tax withholdings)
- Form 940 – annual FUTA return
- State equivalents – each state has its own unemployment tax filing schedule
Fail to file on time, and you’ll get a notice that looks like a bad grade on a report card—except it comes with dollars attached.
5. Pay the Taxes
Most businesses use electronic payroll services (ADP, Gusto, Paychex) that automatically push the funds to the IRS and state agencies. If you’re DIY, you’ll need to set up electronic payments via EFTPS (for federal) and your state’s portal.
6. Keep Records
The law says you must keep payroll records for at least four years. That includes wage statements, tax filings, and proof of payment. Audits are rare, but when they happen, you’ll thank yourself for the tidy spreadsheet Not complicated — just consistent. But it adds up..
Common Mistakes / What Most People Get Wrong
Mistake #1: Treating Employee Benefits as Payroll Taxes
A lot of folks lump health insurance premiums, retirement contributions, and even certain reimbursements into the payroll tax column. So **They’re not. ** Those are benefit expenses, not taxes. You still report them on Form W‑2 (Box 12), but you don’t send them to the IRS as payroll tax Nothing fancy..
Mistake #2: Forgetting State-Specific Taxes
Some states have additional payroll taxes that are easy to overlook—like California’s State Disability Insurance (SDI) or Washington’s Paid Family and Medical Leave tax. Those are employer‑paid, but they’re not part of the federal trio. If you think “only FICA, FUTA, SUTA matter,” you’ll be surprised when a state audit shows a missing line item Small thing, real impact..
Mistake #3: Mis‑classifying Workers
If you label a contractor as an employee just to avoid the paperwork, you’ll still owe the employer payroll taxes on their wages. The IRS uses the “right‑to‑control” test, and getting it wrong can lead to back‑pay of all employer taxes, plus penalties.
Mistake #4: Assuming All Payroll Taxes Are Federal
A common myth is that “payroll tax” automatically means “federal tax.” In reality, state unemployment taxes (SUTA) and local occupational taxes are also payroll‑related, but they’re not federal. Ignoring them can trigger state penalties that stack on top of federal ones.
Mistake #5: Over‑paying the “Except” Items
Some small businesses mistakenly pay state income tax withholding as an employer payroll tax. Consider this: it’s actually the employee’s responsibility, withheld and remitted by the employer, but not a tax the employer owes on top of wages. Over‑paying it ties up cash and creates a mess when you try to reconcile at year‑end.
Some disagree here. Fair enough.
Practical Tips / What Actually Works
-
Use a Dedicated Payroll Service
Even if you’re a solo founder, services like Gusto or Zenefits automate the matching calculations and keep you compliant with the latest state changes. The fee is a tiny fraction of the cost of a missed filing. -
Create a Payroll Tax Calendar
Mark the quarterly 941 due dates (April, July, October, January) and the annual FUTA deadline (January 31). Add state unemployment filing dates—most states follow a similar schedule, but a few are semi‑annual. -
Separate “Payroll Tax” from “Employee Deductions”
In your accounting software, set up distinct expense accounts:- Employer Payroll Taxes – FICA
- Employer Payroll Taxes – FUTA
- Employer Payroll Taxes – SUTA
- Employee Withholdings – Federal Income Tax
This prevents accidental double‑counting.
-
Run a Quarterly Reconciliation
Pull the payroll register, compare the totals you paid to the amounts shown on your filed 941 and state returns. Spot any mismatches before the IRS does. -
Stay on Top of State Changes
Unemployment tax rates can shift each year based on a state’s experience rating. Subscribe to your state labor department’s newsletter or set a Google Alert for “[Your State] unemployment tax rate change.” -
Audit Your “Except” List Annually
Write down every line item that appears on a pay stub. Ask: “Is this a tax the employer owes, or is it an employee‑only deduction?” If you can’t answer quickly, dig deeper. That’s the fastest way to prune the “except” items.
FAQ
Q: Is the employee’s share of Social Security a payroll tax?
A: No. It’s an employee‑only withholding. The employer matches it, but the employee’s portion isn’t the employer’s tax burden.
Q: Do I have to pay payroll taxes for a part‑time intern?
A: If the intern is classified as an employee and receives wages, yes—you owe the employer’s share of FICA, FUTA, and any applicable SUTA. Unpaid internships that meet the “learning experience” criteria are exempt Simple as that..
Q: Are local city taxes considered employer payroll taxes?
A: Only if the city imposes a tax that the employer must remit based on wages (e.g., Chicago’s Payroll Expense Tax). Most local taxes are either employee withholdings or unrelated business taxes Easy to understand, harder to ignore. But it adds up..
Q: How does the Affordable Care Act (ACA) factor into payroll taxes?
A: The ACA’s employer shared responsibility penalty is not a payroll tax. It’s a separate penalty assessed if you don’t offer affordable coverage to full‑time employees.
Q: Can I deduct employer payroll taxes as a business expense?
A: Yes. All employer‑paid payroll taxes (FICA match, FUTA, SUTA, state disability taxes) are deductible ordinary and necessary business expenses on your federal tax return.
When you finally separate the wheat from the chaff—knowing which taxes are truly employer payroll taxes and which are the “except” items—you’ll see a clearer picture of your labor costs. That clarity translates into better budgeting, fewer penalties, and a smoother conversation with anyone who asks, “Why is my paycheck showing this deduction?”
So next time you pull up a pay stub, you’ll be able to point out the exact line items the company has to pay, and the ones it doesn’t. And that, my friend, is the kind of practical knowledge that keeps a business healthy and its employees happy. Happy payrolling!
