Section 125 Health Benefits in North Carolina: What Employees Should Know
Section 125 health benefits in North Carolina let employees pay premiums before federal income tax, Social Security tax and Medicare tax. North Carolina's flat state income tax may shrink too, depending on how payroll handles withholding. This guide shows a worked monthly example, how to read the line on a pay stub, when an election can change, which North Carolina marketplace facts matter if you decline your employer's plan, and an email to send HR.
- Employee-paid health premiums through a cafeteria plan are exempt from income tax withholding, Social Security tax and Medicare tax (IRS Publication 15-B, 2026).
- The employee share of FICA is 7.65%, made up of 6.2% Social Security and 1.45% Medicare, and the Social Security wage base is $184,500 in 2026 (IRS Publication 15, 2026).
- North Carolina's flat income tax rate is scheduled to fall to 3.49% starting in 2027 under S.B. 257, with further cuts planned through 2034 (EY Tax News, July 2026).
- North Carolina uses HealthCare.gov, and 761,457 people picked a plan for 2026, down nearly 22% from 975,110 a year earlier (healthinsurance.org, 2026).
- Cigna is leaving the North Carolina marketplace for 2027, leaving five insurers (healthinsurance.org, 2026).
If you work in North Carolina and see a Section 125 line on your pay stub, the short answer is that it is probably your health premium, taken out before most taxes. North Carolina adds a flat state tax on top of the federal picture. This guide shows what you save, when you can change it, and what to ask HR if a deduction surprised you.

What are Section 125 health benefits in North Carolina?
Section 125 health benefits in North Carolina are health, dental or vision premiums that your employer lets you pay with pay that has not been taxed yet. The federal rule is the same in every state.
A Section 125 plan, also called a cafeteria plan, is a written employer plan that lets employees choose between cash pay and certain benefits. A cafeteria plan can offer accident and health coverage, dependent care assistance, group-term life insurance and an HSA (IRS Publication 15-B, 2026). Employee-paid accident and health benefits are exempt from income tax withholding, Social Security tax and Medicare tax (IRS Publication 15-B, 2026). Benecor's Section 125 pre-tax guide covers the federal rules in more detail.
Does North Carolina tax Section 125 health contributions?
North Carolina has a flat individual income tax, and whether your premium also lowers your state withholding depends on how your employer's payroll is set up. Ask payroll before you count on that part of the savings.
The rate is on a downward path. S.B. 257 lowers North Carolina's rate from 3.99% to 2.99% over seven years: 3.49% for 2027 through 2029, 3.24% for 2030 through 2032, and 2.99% for 2033 and 2034. Up to two more cuts are possible from 2035 if state revenue targets are met (EY Tax News, July 2026). The 3.99% figure in the table below is the rate before the 2027 change, so your own state savings will be smaller from 2027.
How much does a Section 125 plan save a North Carolina employee?
A Section 125 plan saves a North Carolina employee at least 19.65 cents on each pre-tax premium dollar at a 12% federal bracket. That is 7.65% FICA plus 12% federal income tax. State savings come on top if your payroll applies them.
FICA is the payroll tax that funds Social Security and Medicare. The employee share is 7.65% (IRS Publication 15, 2026). The federal bracket in the table is an example. Your own bracket may differ.
| Tax | Rate | Monthly savings |
|---|---|---|
| FICA (Social Security and Medicare) | 7.65% | $30.60 |
| Federal income tax | 12% | $48.00 |
| Subtotal, federal only | 19.65% | $78.60 |
| North Carolina income tax, if payroll excludes the premium | 3.99% | $15.96 |
| Total with North Carolina income tax | 23.64% | $94.56 |
Your real number depends on your bracket and how payroll applies state withholding. Higher earners above the Social Security wage base of $184,500 stop paying the 6.2% part for the rest of the year (IRS Publication 15, 2026).
How do I read the Section 125 line on my North Carolina pay stub?
The Section 125 line on your North Carolina pay stub shows the total of your pre-tax benefit deductions for that pay period. Common labels include Sec 125, Cafe 125, S125 and Pre-tax medical.
Check these three things on your stub:
- The amount per pay period. Multiply by the number of pay periods to see your yearly total.
- The benefits inside it. Medical, dental and vision are often bundled into one line.
- Your W-2. Box 1 should show wages after pre-tax deductions, and Box 14 may show a Section 125 or cafeteria plan label. Compare Box 1 with your Social Security and Medicare wage boxes.
Benecor's W-2 Box 14 guide explains the labels employers use.
Can I change my Section 125 election mid-year in North Carolina?
You can usually change your Section 125 election mid-year only after a qualifying life event that your plan allows. Federal rules lock elections for the plan year unless an event such as marriage, birth, divorce or a loss of other coverage occurs (26 CFR 1.125-4, 2026).
Your employer's plan document decides which events count and how long you have to ask. Many plans give 30 days. Ask HR for the plan document and the exact deadline before you assume you can change anything. Benecor's qualifying life events guide lists the common ones.
What if I decline my employer's plan in North Carolina?
If you decline your employer's health plan in North Carolina, you need other coverage, and the marketplace is HealthCare.gov. North Carolina had 761,457 plan selections in 2026 open enrollment, down nearly 22% from 975,110 the year before, which healthinsurance.org links mainly to the end of the enhanced federal subsidies.
| Fact | Figure | Source |
|---|---|---|
| 2026 open enrollment sign-ups | 761,457 people | healthinsurance.org, 2026 |
| 2025 open enrollment sign-ups | 975,110 people | healthinsurance.org, 2026 |
| Sign-ups eligible for premium tax credits, 2026 | About 87%, averaging $660 a month | healthinsurance.org, 2026 |
| Insurers in 2027 | Five, down from six; Cigna exits | healthinsurance.org, 2026 |
| Lowest 2027 rate changes | Ambetter 8.4%, AmeriHealth Caritas 9.3% | healthinsurance.org, 2026 |
| Highest 2027 rate changes | Oscar 16.5%, UnitedHealthcare 27.4% | healthinsurance.org, 2026 |
| Blue Cross and Blue Shield of NC 2027 change | 15.8% | healthinsurance.org, 2026 |
| Medicaid expansion | Took effect December 1, 2023 | healthinsurance.org, 2026 |
Those rate changes are before subsidies, and your own plan price can differ. Open enrollment for 2027 coverage starts November 1, 2026. Confirm the final deadline and the cutoff for a January 1 start on HealthCare.gov. Premiums paid through Section 125 come out before federal income tax and FICA (IRS Publication 15-B, 2026), which lowers what employer coverage costs you. Compare that with a marketplace quote before you decline.
How do I ask HR about my Section 125 plan?
