Every fall, millions of employees face open enrollment — and the decisions you make about **health FSAs** and **commuter benefits** can save (or cost) you hundreds of dollars in taxes. For 2026, the IRS has indexed both limits upward, making pre-tax benefits even more valuable.

Use the [FSA & Commuter Benefits Calculator](/tools/fsa-commuter-benefits-calculator) to estimate your total tax savings.

## How Pre-Tax Benefits Save Money

When you contribute to a health FSA or commuter benefit account, the money comes out of your paycheck **before** taxes are calculated. This reduces both:

- **Federal income tax** (at your marginal rate)
- **FICA taxes** — Social Security and Medicare (7.65% for most employees)

This is more powerful than a 401(k) contribution, which saves income tax but **not** FICA. For someone in the 22% bracket, pre-tax benefits save roughly **29.65 cents per dollar**.

Your employer sets your plan's limit — it can be anything up to the IRS maximum. Many employers cap contributions below $3,400.

### What FSAs Cover

Health FSAs pay for qualified medical expenses not covered by insurance:

- Copays and deductibles
- Prescription medications
- Dental and vision care (unless you have a limited-purpose FSA)
- Medical equipment and supplies
- Over-the-counter medications (with a prescription historically; now generally allowed)

### The Forfeiture Risk

The biggest FSA downside is **use-it-or-lose-it**. If you contribute $3,400 but only spend $2,500, you may forfeit $900 — which more than wipes out your tax savings.

**Mitigation strategies:**

- Elect only what you expect to spend with high confidence
- Choose a plan with **carryover** (up to $680 rolls forward)
- Choose a plan with a **2.5-month grace period** (spend through March 15)
- Time elective procedures before year-end

## 2026 Commuter Benefit Limits

Qualified transportation fringe benefits cover:

    <td>
      $4,080
    </td>
  </tr>
</tbody>
</table>

These limits increased by $15/month from 2025. Transit and parking are **separate benefits** — you can claim up to $340/month for each if your employer offers both.

### How Commuter Benefits Work

Most employers partner with a benefits administrator. You elect a monthly amount, and it's deducted pre-tax from your paycheck. You typically receive a debit card or voucher for transit, or the parking cost is paid directly.

Unlike FSAs, commuter benefits are **monthly** — you generally cannot stockpile unused amounts.

**Critical rule:** If you are eligible for an HSA, you generally **cannot** contribute to a general-purpose health FSA in the same year. You may still use a **limited-purpose FSA** for dental and vision only.

Compare options with our [HSA Calculator](/tools/hsa-calculator).

## Open Enrollment Strategy

### Step 1: Estimate Medical Expenses

Review last year's out-of-pocket costs. Add planned expenses (glasses, dental work, physical therapy). Elect the FSA amount that matches realistic spending — not your worst-case scenario.

### Step 2: Calculate Commuter Savings

If you have fixed transit or parking costs, commuter benefits are nearly always worth it. A $200/month transit pass saves approximately **$71/month** in taxes for a 22% bracket worker (22% + 7.65% FICA).

### Step 3: Check Employer Match

Some employers contribute to FSAs or HSAs. Factor employer contributions into your total benefits picture.

### Step 4: Consider Dependent Care FSA

Separate from health FSA, the **dependent care FSA** allows up to $5,000 pre-tax for childcare expenses ($2,500 if married filing separately). This is not included in our calculator but is worth evaluating during open enrollment.

## Real-World Example

**Profile:** $85,000 salary, 22% marginal rate, $3,000 health FSA, $200/month transit.

<thead>
  <tr>

    <th>

    </th>
    
    <th>
      Tax Savings (22% + 7.65%)
    </th>
  </tr>
</thead>

<tbody>
  <tr>
    <td>
      Health FSA
    </td>
    
    <td>
      $3,000
    </td>
    
    <td>
      $889
    </td>
  </tr>
  
  <tr>
    <td>
      Transit
    </td>
    
    <td>
      $2,400
    </td>
    
    <td>
      $711
    </td>
  </tr>
  
  <tr>
    <td>
      <strong>
        Total
      </strong>
    </td>
    
    <td>
      <strong>
        $5,400
      </strong>
    </td>
    
    <td>
      <strong>
        $1,600
      </strong>
    </td>
  </tr>
</tbody>
</table>

That's $1,600 in tax savings for expenses you would have paid anyway.

## Common Mistakes

**Over-funding the FSA:** The #1 FSA mistake. A $1,000 forfeiture costs more than the tax savings on that $1,000.

**Skipping commuter benefits:** Many employees don't realize their employer offers them. Ask HR during open enrollment.

**Confusing FSA and HSA:** Contributing to both (when ineligible) can disqualify your HSA and trigger penalties.

**Forgetting FICA savings:** When comparing benefits, include the 7.65% FICA savings — not just income tax.

## Key Takeaways

- 2026 health FSA: **$3,400** limit, **$680** max carryover
- Commuter transit and parking: **$340/month** each
- Pre-tax benefits save **income tax + FICA** (29.65% for a 22% bracket worker)
- Budget FSA carefully to avoid forfeiture
- HSA-eligible employees generally cannot use a general health FSA
- Dependent care FSA ($5,000) is a separate valuable benefit
