Are Employee Health Insurance Premiums Tax-Deductible?

For most workers, employee health insurance premiums are not separately tax deductible, because they’re already withheld from your paycheck before income and payroll taxes are calculated. You get the tax break automatically, and claiming it again on your return would be a double benefit the IRS doesn’t allow. Premiums paid with after-tax dollars are a different story: those can be deducted, but only if you itemize on Schedule A and your total medical expenses exceed 7.5% of your adjusted gross income.1Office of the Law Revision Counsel. 26 USC 213 – Medical, Dental, Etc., Expenses

Why Pre-Tax Premiums Aren’t Deductible Again

Most employer health plans run premiums through a cafeteria plan under Section 125 of the Internal Revenue Code.2Office of the Law Revision Counsel. 26 USC 125 – Cafeteria Plans Your share of the premium is subtracted from gross pay before federal income tax, Social Security, and Medicare are calculated. Those dollars never count as taxable wages in the first place.

Whatever your employer kicks in is also excluded from your income under Section 106.3Office of the Law Revision Counsel. 26 USC 106 – Contributions by Employer to Accident and Health Plans If your employer pays $6,000 toward your family plan and you contribute $3,000 pre-tax, none of that $9,000 shows up as income to you. Because the money was never taxed, you can’t deduct it.

Checking Your W-2

Box 1 of your W-2, “Wages, tips, other compensation,” already reflects pre-tax deductions. If premiums came out under a Section 125 plan, they’ve been stripped out of Box 1. Your final pay stub of the year will show the health insurance line as a pre-tax deduction.

You may also see a figure in Box 12 with Code DD. That reports the total cost of your employer-sponsored coverage and is informational only. It doesn’t go anywhere on your return.4Internal Revenue Service. Reporting Employer-Provided Health Coverage on Form W-2

When Employee Premiums Are Actually After-Tax

Not every employer runs a cafeteria plan. Some smaller employers deduct premiums after taxes have already been withheld. When that happens, you paid with dollars that stayed in your taxable wages, and those premiums become eligible medical expenses.

Other common situations where premiums are after-tax:

  • COBRA continuation coverage after leaving a job. You typically pay the full premium yourself with after-tax money, and it counts as a medical expense on Schedule A.5Internal Revenue Service. Publication 502 – Medical and Dental Expenses
  • Standalone dental or vision policies purchased outside an employer plan.5Internal Revenue Service. Publication 502 – Medical and Dental Expenses
  • Supplemental policies like critical illness or hospital indemnity coverage bought independently.
  • Marketplace plans purchased through the federal or state exchange. Premiums are paid after-tax, but you must subtract any Premium Tax Credit before counting the premiums as a medical expense.5Internal Revenue Service. Publication 502 – Medical and Dental Expenses

The Marketplace math trips up a lot of filers. If your total annual premium is $8,700 and you receive a $3,600 Premium Tax Credit, only $5,100 counts as your deductible medical expense. Getting it wrong will trigger a mismatch notice.

The 7.5% AGI Floor

Even when premiums are after-tax, you can only deduct total medical and dental expenses that exceed 7.5% of your adjusted gross income.1Office of the Law Revision Counsel. 26 USC 213 – Medical, Dental, Etc., Expenses This threshold is permanent.

The math is straightforward. Say your AGI is $70,000. Multiply by 7.5% and you get $5,250. If your total qualifying medical expenses for the year, including after-tax premiums, co-pays, prescriptions, and other out-of-pocket costs, add up to $9,000, only the $3,750 above the floor is deductible. Everything below the line is invisible to your return.

Itemizing vs. the Standard Deduction

You can only claim the medical expense deduction if you itemize on Schedule A instead of taking the standard deduction. For tax year 2026, the standard deduction is $16,100 for single filers, $24,150 for heads of household, and $32,200 for married couples filing jointly.6Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 Itemizing only helps when your total itemized deductions, including medical, state and local taxes, mortgage interest, and charitable gifts, exceed the standard deduction.

For most wage earners, the standard deduction wins. The medical expense deduction realistically pays off for people with unusually high healthcare spending relative to their income: someone recovering from major surgery, managing an expensive chronic condition, or paying full-price COBRA premiums during a stretch without a job.

Whose Premiums You Can Include

You’re not limited to your own coverage. After-tax premiums you pay for your spouse, your dependents, and in some cases near-dependents count as medical expenses.5Internal Revenue Service. Publication 502 – Medical and Dental Expenses

Children of divorced or separated parents get special treatment. Either parent can deduct medical expenses paid for the child, as long as the child lived with one or both parents for more than half the year and received more than half their support from the parents combined. It doesn’t matter which parent claims the child as a dependent.5Internal Revenue Service. Publication 502 – Medical and Dental Expenses

You can also include premiums for someone who would have qualified as your dependent except that they earned too much gross income or filed a joint return. If you already had family coverage and adding that person didn’t raise your premium, you can still include the full premium.

How to Claim the Deduction

If you’re deducting after-tax premiums as an itemized medical expense, use Schedule A (Form 1040).7IRS. 2025 Instructions for Schedule A (Form 1040) Total every qualifying medical expense for the year, including premiums, co-pays, prescriptions, and other unreimbursed costs. Enter the total on Line 1. The form walks you through subtracting 7.5% of AGI on Line 3, and the remainder flows into your total itemized deductions.

Records to pull together before filing:

  • Your W-2, to confirm whether premiums were already handled pre-tax.
  • Premium statements from your insurer showing what you paid.
  • Form 1095-A if you bought coverage through the Marketplace, showing premiums paid and any advance Premium Tax Credit.
  • Receipts for co-pays, prescriptions, lab fees, and other expenses that combine with premiums to reach the 7.5% floor.

Electronic returns are generally processed within 21 days. Paper returns take much longer, with the IRS reporting a backlog stretching several months for paper Form 1040s.8Internal Revenue Service. Processing Status for Tax Forms Keep copies of everything for at least three years after filing.

If the IRS Questions What You Claimed

When the numbers on your return don’t match what third parties reported, the IRS typically sends a CP2000 notice. This isn’t an audit or a bill. It’s a letter identifying a discrepancy and proposing changes.9Internal Revenue Service. Understanding Your CP2000 Series Notice You’ll have a deadline to respond, and you can agree, partially agree, or disagree by submitting documentation. The fastest response is through the IRS document upload tool referenced in the notice.

If you claimed medical expenses you weren’t entitled to and the error results in a substantial understatement of tax, the IRS can impose an accuracy-related penalty of 20% on the underpayment.10Office of the Law Revision Counsel. 26 USC 6662 – Imposition of Accuracy-Related Penalty on Underpayments “Substantial” generally means the underpayment exceeds the greater of 10% of the tax that should have been shown or $5,000. The penalty is avoidable if you can show reasonable cause and good faith, which is where thorough recordkeeping pays off. Honest mistakes with documentation rarely escalate. Inflated or fabricated expenses are a different matter.
