Section 125 vs. Simply Raising Salaries: A Tax Comparison
Every business owner who learns about Section 125 plans eventually asks the same question: “Why don’t I just give my employees a raise instead?”
It’s a fair question. If the goal is to help employees cover health insurance, daycare, and medical expenses, why not skip the paperwork and simply increase their salaries? They can buy whatever they need with the extra cash.
The answer comes down to math. And the math isn’t close.
When you route money through a Section 125 plan, both you and your employees keep more of it. When you give a straight salary increase for the same dollar amount, a significant chunk goes to taxes before anyone benefits. Let’s walk through the numbers.
The Side-by-Side Comparison
Let’s say you want to help an employee cover $5,000 in annual expenses — health insurance premiums, out-of-pocket medical costs, or dependent care. You have two options:
Option A: Give them a $5,000 salary increase Option B: Provide $5,000 in pre-tax benefits through a Section 125 plan
Here’s what actually happens with each approach.
Option A: The $5,000 Salary Increase
When you add $5,000 to an employee’s salary, both sides get taxed on that money:
Employer costs on the $5,000 raise:
| Tax | Rate | Cost |
|---|---|---|
| Social Security (employer share) | 6.2% | $310 |
| Medicare (employer share) | 1.45% | $72.50 |
| Federal unemployment (FUTA) | 0.6% | $30 |
| State unemployment (avg.) | ~2.5% | $125 |
| Workers’ compensation (avg.) | ~1.5% | $75 |
| Total employer cost on $5,000 | $612.50 |
Your actual cost to give a “$5,000 raise” is $5,612.50.
What the employee actually receives from the $5,000:
| Tax | Rate | Amount |
|---|---|---|
| Federal income tax | 22% | $1,100 |
| Social Security | 6.2% | $310 |
| Medicare | 1.45% | $72.50 |
| State income tax (avg.) | ~5% | $250 |
| Total taxes on $5,000 | $1,732.50 |
The employee’s take-home from the $5,000 raise: $3,267.50
So you spent $5,612.50, and your employee received $3,267.50 in purchasing power. That’s a 42% efficiency loss — nearly half the money went to taxes.
Option B: $5,000 Through Section 125
When the same $5,000 goes through a Section 125 plan as pre-tax benefits (health premiums, FSA contributions, or DCAP contributions):
Employer costs:
| Item | Cost |
|---|---|
| Benefit amount | $5,000 |
| FICA on $5,000 | $0 (pre-tax benefits are exempt) |
| FUTA on $5,000 | $0 |
| Workers’ comp on $5,000 | $0 |
| Total employer cost | $5,000 |
Actually, it’s even better than that. Because the $5,000 in pre-tax deductions reduces the employee’s taxable wages, the employer saves 7.65% in FICA on that amount: $382.50 in savings.
What the employee actually receives:
The full $5,000 goes toward qualified benefits — no income tax, no FICA, no state tax. The employee gets $5,000 in benefit value.
The Comparison
| Salary Increase | Section 125 | |
|---|---|---|
| Employer cost | $5,612.50 | $5,000 (or less with FICA savings) |
| Employee benefit value | $3,267.50 | $5,000 |
| Total taxes paid | $2,345 | $0 |
| Efficiency | 58% | 100% |
For every dollar you spend, Section 125 delivers 72% more value to your employee. Or to put it differently: a $5,000 Section 125 benefit is equivalent to a $7,650 salary increase in terms of purchasing power for the employee.
Scaling the Numbers: What This Means for Your Business
Let’s look at this across a real workforce.
Company: 30 Employees, $4,000 Average Pre-Tax Deductions
If you gave everyone a $4,000 raise instead:
| Item | Amount |
|---|---|
| Total salary increase | $120,000 |
| Additional employer FICA | $9,180 |
| Additional FUTA | $720 |
| Additional workers’ comp (~1.5%) | $1,800 |
| Total employer cost | $131,700 |
| Employee take-home (after ~35% taxes) | $78,000 |
With Section 125 instead:
| Item | Amount |
|---|---|
| Total pre-tax benefits | $120,000 |
| Additional employer FICA | $0 |
| Employer FICA savings | -$9,180 |
| TPA administration cost | ~$1,500 |
| Total employer cost | $112,320 |
| Employee benefit value | $120,000 |
The difference:
- Employer saves $19,380/year by using Section 125 instead of salary increases
- Employees receive $42,000 more in effective value
- Combined tax savings: $61,380/year
That’s real money that stays in your company and your employees’ pockets instead of going to taxes.
The Break-Even Question
Is there ever a scenario where a salary increase is the better move? Yes — but the situations are narrow.
When Salary Might Be Better
Low-income employees who don’t benefit from pre-tax deductions. If an employee’s income is low enough that they’re in the 10% or 12% federal bracket and they owe minimal FICA (perhaps they have multiple jobs and have already hit the Social Security wage base), the tax savings from Section 125 are smaller. A direct raise might be more useful because it gives them flexibility to spend the money on anything, not just qualified benefits.
Employees who don’t need the specific benefits. Section 125 only works for qualified expenses — health premiums, FSA-eligible medical costs, and dependent care. If an employee has no health insurance costs and no dependents, they can’t use a DCAP or medical FSA effectively. A raise lets them put the money wherever they need it.
Recruitment situations where base salary matters. Some candidates evaluate offers primarily on base salary. A higher number on the offer letter can be more compelling than explaining the tax advantages of pre-tax benefits, even if the net financial picture favors Section 125.
When Section 125 Always Wins
For any employee who:
- Pays a share of health insurance premiums
- Has out-of-pocket medical expenses
- Pays for daycare, preschool, or eldercare
- Is in the 22% federal tax bracket or higher
Section 125 is the more efficient vehicle. Period.
And here’s the thing: the two aren’t mutually exclusive. You can (and should) offer a Section 125 plan and competitive salaries. The Section 125 plan simply ensures that benefit dollars are delivered as efficiently as possible.

The Hidden Costs of Higher Salaries
Beyond the direct tax comparison, salary increases have compounding cost implications that pre-tax benefits don’t:
Salary Is Permanent
A raise is a permanent increase to your compensation structure. It affects:
- Future raises — percentage-based increases compound on a higher base
- Overtime calculations — overtime pay is based on regular rate of pay
- Retirement plan contributions — if you match 401(k) contributions as a percentage of salary, a higher salary increases your matching obligation
- Severance and unemployment — both are typically calculated on salary
Pre-tax benefits through Section 125, on the other hand, are elected annually. They don’t inflate your base compensation structure.
Salary Expectations Ratchet Up
Once you give a raise, employees expect to keep it — and expect future raises on top of it. Benefits dollars, while valued, don’t create the same upward pressure on base compensation.
Workers’ Compensation Premiums
Workers’ comp premiums are calculated based on payroll. Higher salaries mean higher premiums. Pre-tax benefit deductions actually reduce your workers’ comp exposure.
A Practical Approach
The most effective strategy isn’t “Section 125 OR salary.” It’s using both tools intelligently:
- Pay competitive base salaries — you need to attract and retain good people
- Set up a Section 125 plan to make benefit costs as tax-efficient as possible
- When you have additional budget for compensation, consider whether the next dollar is better spent as salary or as enhanced pre-tax benefits
For most businesses, the answer is clear: benefits dollars routed through Section 125 deliver significantly more value per dollar spent than equivalent salary increases. The math doesn’t lie.

The question isn’t whether you should offer competitive pay. Of course you should. The question is whether the dollars you’re already spending on benefits are being delivered in the most tax-efficient way possible. For most businesses, the answer is no — and the fix is straightforward.
