Most health insurance premiums are not tax-deductible, but self-employed people and business owners have options

If you pay for health insurance yourself, you generally cannot deduct those premiums on your federal tax return. The IRS treats health insurance as a personal expense, similar to groceries or utilities. However, if you are self-employed, own a business, or work for a company that offers a cafeteria plan, you may have a path to reduce your taxable income through health insurance costs.

The key distinction is whether your employer pays part of the premium or whether you pay the full amount yourself. If your employer covers any portion, that amount is already excluded from your taxable wages — you do not pay income tax on it. If you pay out of pocket, the rules depend on your employment status and the type of plan you use.

Key Takeaways

  • Self-employed people can deduct 100% of health insurance premiums paid for themselves, spouses, and dependents as an above-the-line deduction on Form 1040.
  • S-corporation and C-corporation owners can deduct premiums only if the policy is in the business's name and premiums are paid by the business, not reimbursed to the owner.
  • Employees covered by employer plans cannot deduct premiums, but can reduce taxable income through pre-tax payroll deductions if the employer offers them.
  • Health Savings Accounts (HSAs) paired with high-deductible plans allow you to set aside pre-tax dollars specifically for medical expenses, including some insurance costs.
  • Medicare premiums, long-term care insurance, and supplemental policies have different rules and generally cannot be deducted unless you are self-employed.

Self-employed health insurance deduction

If you are self-employed — meaning you file Schedule C and pay self-employment tax — you can deduct 100% of health insurance premiums you pay for yourself, your spouse, and your dependents. This deduction appears on line 29 of Form 1040 and reduces your adjusted gross income (AGI) before you calculate the standard deduction or itemized deductions.

The policy must be in your name or your spouse's name, and you cannot claim this deduction for any month in which you were may be able to access to enroll in an employer-sponsored plan through your own employment or your spouse's employment. If you have employees, you can also deduct premiums you pay for their health insurance as a business expense on Schedule C, but employee premiums are not subject to this same rule — they are straightforward a business deduction.

This deduction is available whether you itemize or take the standard deduction, which makes it particularly valuable. You do not need to have net profit from self-employment to claim it, but the deduction cannot exceed your net self-employment income for the year.

Business owners and S-corporation or C-corporation structure

If you own an S-corporation or C-corporation, the deduction rules are stricter. The health insurance policy must be owned by the business, not by you personally, and the business must pay the premiums directly to the insurance company. You cannot pay the premiums yourself and then have the business reimburse you — that reimbursement is treated as taxable wages to you.

For S-corporation owners, premiums paid by the business are deductible as a business expense, but they are also added to your W-2 wages as taxable income. This means you get the deduction on the business side but pay income tax on the amount as an employee. Self-employment tax does not explore to this amount, which is one advantage over sole proprietorship.

For C-corporation owners, premiums paid by the business are a deductible business expense and are not added to your personal income at all. This is a significant tax advantage if your corporation has sufficient profit to absorb the cost.

Employee coverage through employer plans

If your employer offers health insurance and deducts premiums from your paycheck before taxes are calculated, those premiums are already excluded from your taxable income. You do not get an additional deduction because the tax benefit has already been applied. This is called a pre-tax payroll deduction, and it reduces both your income tax and your self-employment tax (if applicable).

If your employer offers a Section 125 cafeteria plan or flexible spending account (FSA), you can set aside additional pre-tax dollars to pay for out-of-pocket medical expenses, including copays, deductibles, and certain over-the-counter items. Money placed in an FSA is not subject to income tax or payroll tax, but you must spend it within the plan year or lose it — there is no carryover (with limited exceptions for dependent care FSAs).

If you are an employee and pay premiums out of pocket after taxes have been withheld, you cannot deduct those premiums on your tax return. Your only option is to ask your employer whether they offer a pre-tax payroll deduction plan.

Health Savings Accounts and high-deductible plans

A Health Savings Account (HSA) is a tax-advantaged savings account available only if you are enrolled in a high-deductible health plan (HDHP). You can contribute pre-tax dollars to an HSA, and those dollars can be used to pay for may have access to medical expenses, including insurance premiums in certain situations.

HSA contributions reduce your taxable income dollar-for-dollar. For 2024, the contribution limit is $4,150 for individual coverage and $8,300 for family coverage (these limits change annually). You can use HSA funds to pay for the HDHP premium itself only if you are receiving unemployment benefits, but you can use HSA funds to pay for other health insurance premiums, including Medicare premiums, COBRA continuation coverage, and long-term care insurance premiums.

HSAs are portable — if you change jobs, the account stays with you. Unlike FSAs, unused HSA funds roll over year to year and can be invested for growth. This makes HSAs one of the most tax-efficient ways to set aside money for health expenses over time.

Medicare and supplemental insurance premiums

Medicare premiums (Parts A, B, and D) and Medigap supplemental insurance premiums are generally not tax-deductible for most people. However, if you are self-employed, you can deduct Medicare premiums under the self-employed health insurance deduction rule described above. This includes Medicare Part B premiums, Part D prescription drug premiums, and Medigap policy premiums.

Long-term care insurance premiums are also not deductible for most taxpayers, with one exception: if you are self-employed, a portion of long-term care premiums may be deductible as part of your self-employed health insurance deduction, subject to age-based limits set by the IRS. These limits vary by age and are adjusted annually.

If you are retired and receiving Social Security, Medicare premiums are often deducted directly from your benefit check, which means you never see the money and cannot deduct it. The same applies if your employer deducts premiums from your pension or retirement income.

Itemized deductions and medical expenses

Even if you cannot deduct health insurance premiums directly, you may be able to include them as part of your medical expense deduction if you itemize deductions on Schedule A. However, this route is rarely worthwhile because medical expenses must exceed 7.5% of your adjusted gross income before you can deduct any amount, and you can only deduct the excess.

For example, if your AGI is $60,000, you must have more than $4,500 in medical expenses before you can deduct anything. If you have $5,500 in total medical expenses (including insurance premiums), you can only deduct $1,000. Most people benefit more from the standard deduction than from itemizing, so this strategy makes sense only if you have very high medical expenses in a single year or a very low AGI.

Frequently Asked Questions

Can I deduct health insurance premiums if I am unemployed?

If you received unemployment benefits during the year, you can deduct 100% of health insurance premiums you paid for yourself, your spouse, and your dependents. This deduction is available whether you are self-employed, an employee, or unemployed. You claim it on line 21 of Form 1040 as an above-the-line deduction.

What if my employer reimburses me for health insurance I paid out of pocket?

If your employer reimburses you for premiums you paid personally, that reimbursement is taxable income to you unless it is part of a formal accountable plan. An accountable plan requires you to submit receipts and comply with specific IRS rules. If your employer has such a plan in place, the reimbursement is not taxable. Ask your HR department whether they offer one.

Can I deduct health insurance premiums for my adult child?

If your adult child is your dependent for tax purposes, you can deduct their health insurance premiums if you are self-employed. If you are an employee, you cannot deduct premiums, but your employer may allow you to cover your dependent under a pre-tax payroll deduction plan. Check with your benefits administrator.

Does COBRA continuation coverage count as a deductible expense?

If you are self-employed, COBRA premiums are deductible under the self-employed health insurance deduction. If you are not self-employed, COBRA premiums are not deductible unless you are receiving unemployment benefits, in which case you can deduct them. You can also pay COBRA premiums using pre-tax HSA funds if you are enrolled in an HDHP.

What records do I need to claim the self-employed health insurance deduction?

Keep copies of your insurance policy, premium payment receipts or statements, and cancelled checks or bank statements showing payment. The IRS does not require you to attach these documents to your return, but you must have them available if your return is audited. Your insurance company can provide a year-end statement showing total premiums paid.
