17.3 Taxation of Health Insurance

Taxation of Health Insurance

Tax treatment is one of the most heavily tested national topics. The governing question is always: Were the premiums paid with pre-tax or after-tax dollars? That answer determines whether benefits are taxable. The general rule for accident and health insurance:

• Premiums paid with after-tax dollars → benefits received tax-free.
• Premiums deducted/excluded (pre-tax) → benefits may be taxable.

This symmetry runs through every scenario below. Memorize it before drilling the exceptions.

Individual (Personally Owned) Health Insurance

For a personally owned medical expense policy, premiums are paid with after-tax dollars, so benefits are received income-tax-free. Premiums are generally not deductible, except that unreimbursed medical expenses (including premiums) are deductible only to the extent they exceed 7.5% of adjusted gross income (AGI) and the taxpayer itemizes.

Worked example: A taxpayer has $60,000 AGI and $6,000 of unreimbursed medical costs.

• 7.5% threshold = 0.075 × $60,000 = $4,500.
• Deductible amount = $6,000 − $4,500 = $1,500.

For individual disability income (DI) insurance, the same logic applies: premiums are paid after-tax and are not deductible, so benefits are received tax-free. This is why personally purchased DI benefits never appear as taxable income.

Group (Employer-Provided) Health Insurance

Employer-paid group medical premiums are a deductible business expense to the employer and are not taxable income to the employee. Medical benefits the employee receives are still tax-free.

Group disability income is the key trap. When the employer pays the premium (a pre-tax benefit to the worker):

• The benefits the employee later receives are taxable income.

When the employee pays the premium with after-tax dollars, the benefits are tax-free. If costs are shared, benefits are taxable in proportion to the employer-paid share.

Health Savings Accounts (HSAs)

An HSA is a tax-advantaged account that must be paired with a High-Deductible Health Plan (HDHP). HSAs offer a triple tax advantage:

1. Contributions are tax-deductible (or pre-tax via payroll).
2. Earnings grow tax-deferred.
3. Withdrawals for qualified medical expenses are tax-free.

Rules to memorize:

• Must be covered by a qualifying HDHP and have no other disqualifying coverage (and not be enrolled in Medicare).
• Funds roll over year to year — no use-it-or-lose-it.
• Account is portable and owned by the individual.
• Non-qualified withdrawals before age 65 are taxed as income plus a 20% penalty. After age 65, non-qualified withdrawals are taxed as income but the 20% penalty no longer applies (functioning like a traditional retirement account).

HSA Worked Example

A 40-year-old account holder withdraws $2,000 for a non-medical expense; they are in the 22% income-tax bracket.

• Income tax: 0.22 × $2,000 = $440.
• Penalty: 0.20 × $2,000 = $400.
• Total tax cost = $840, leaving only $1,160 usable.

Had the same $2,000 been used for a qualified medical expense, it would be entirely tax-free ($0 cost). If the holder were age 67, only the $440 income tax would apply (no $400 penalty), leaving $1,560.

Trap: The 20% penalty is HSA-specific — do not confuse it with the 10% early-withdrawal penalty on retirement accounts.

Self-Employed Individuals

A self-employed person may take an above-the-line deduction for 100% of health insurance premiums paid for themselves, a spouse, and dependents — without itemizing and without the 7.5%-of-AGI floor. The deduction cannot exceed the net profit from the business and is unavailable for any month the person could join a spouse's employer plan.

Key distinctions:

• Medical premiums: 100% deductible above-the-line for the self-employed.
• Disability income premiums: still not deductible (so DI benefits remain tax-free, consistent with the general rule).
• Self-employed individuals can also fund and deduct HSA contributions.

Other Taxable and Tax-Free Health Benefits

Several specialty arrangements follow the same after-tax / pre-tax logic and appear on the exam:

• Business Overhead Expense (BOE) insurance — premiums are deductible as a business expense, so the benefits are taxable. (It reimburses rent, utilities, and staff salaries while an owner is disabled.)
• Key person disability — premiums are not deductible to the employer, so benefits are received tax-free.
• Accidental Death & Dismemberment (AD&D) and medical reimbursements paid to the insured are generally tax-free.
• Flexible Spending Account (FSA) salary deferrals are pre-tax; qualified reimbursements are tax-free, but unused funds are largely forfeited (use-it-or-lose-it), unlike an HSA.

HSA Contribution Limits and Comparison

HSA contributions are capped annually by the IRS, with separate self-only and family limits, plus a catch-up contribution for account holders age 55 and older. Contributions for a given year may be made up to the tax-filing deadline. Exceeding the limit triggers a 6% excise tax on the excess each year it remains.

Trap: A Health Reimbursement Arrangement (HRA) is funded only by the employer; the employee cannot contribute, and reimbursements are tax-free to the employee. Don't confuse HRA funding with HSA or FSA salary deferrals.

Premium and Benefit Taxation Summary

The disability rule is the key trap: who paid the premium with what dollars determines whether the benefit is taxed. After-tax premiums (individual DI) produce tax-free benefits; employer-paid premiums produce taxable benefits.

HSA Triple Tax Advantage

A Health Savings Account paired with a qualifying HDHP offers three tax breaks: contributions are tax-deductible (or pre-tax through payroll), earnings grow tax-free, and withdrawals for qualified medical expenses are tax-free.

Worked example: a worker contributes $3,000 pre-tax to an HSA, reducing taxable income by $3,000. The account earns interest tax-free, and a $3,000 withdrawal for qualified dental and prescription costs is also tax-free a benefit taxed at no point. Non-medical withdrawals before 65 are taxable plus a 20% penalty; after 65 they are taxable only.

Exam Tip: HSA = deductible in, tax-free growth, tax-free qualified withdrawals (triple advantage). Funds roll over and are portable, unlike an FSA.
