Can you confidently advise a client who turns 65 and enrolls in Medicare Part A mid-year regarding their HSA contributions? Many candidates, focused solely on the annual contribution limit, will miscalculate or miss the crucial eligibility cutoff. The CFP Board designs questions to test your judgment on the nuanced interplay of health coverage, age, and enrollment triggers, not just your memory of dollar amounts.
A Health Savings Account (HSA) is a tax-advantaged savings account paired with a high-deductible health plan (HDHP). It offers a triple tax benefit: contributions are tax-deductible, funds grow tax-free, and withdrawals for qualified medical expenses are tax-free. For the CFP exam, mastering HSA rules is non-negotiable.
Key facts
- Purpose: Tax-advantaged savings for qualified medical expenses for those with HDHPs.
- Contribution Limits (2025): $4,300 (self-only), $8,550 (family). These are indexed for inflation annually.
- Catch-up Contribution (2025): Additional $1,000 for account holders age 55 or older.
- HDHP Min. Deductible (2025): $1,650 (self-only), $3,300 (family).
- HDHP Max. Out-of-Pocket (2025): $8,300 (self-only), $16,600 (family).
- Governing Statute: Internal Revenue Code (IRC) § 223.
What Are the Core HSA Rules for the CFP Exam?
An HSA is a tax-advantaged account that empowers individuals with high-deductible health plans (HDHPs) to save for qualified medical expenses. Within the CFP Board's principal knowledge area of Insurance and Risk Management, HSAs are a critical tool. They offer a powerful "triple tax advantage": tax-deductible contributions, tax-free growth, and tax-free withdrawals for qualified expenses.
On the exam, you won't just define an HSA. You will apply the rules in complex client scenarios. Questions test your ability to calculate pro-rata contribution limits, identify qualified distributions under IRC § 213(d), and navigate the strict eligibility requirements, especially around life events like retirement or turning 65. The exam tests judgment, not just recall.

A common mistake is failing to grasp the hard-stop nature of Medicare eligibility. Many candidates incorrectly assume a client can continue contributing after enrolling in Medicare Part A. Examiners use these nuances to separate candidates who understand the application of the rules from those who only memorized the annual limits. Try VoraPrep's free CFP practice questions to see how these scenarios are tested.
How Do You Determine HSA Eligibility and Contribution Limits?
To contribute to an HSA, a client must meet two primary conditions: they must be covered by a qualifying HDHP, and they must not have any other disqualifying health coverage.
For the 2025 tax year, an HDHP must have a minimum annual deductible of $1,650 for self-only coverage or $3,300 for family coverage. The maximum annual out-of-pocket expenses cannot exceed $8,300 for self-only or $16,600 for family coverage. These thresholds are adjusted for inflation annually; the CFP exam will always provide the relevant year's limits in the question prompt.
The 2025 maximum contribution is $4,300 for self-only coverage and $8,550 for family coverage. Individuals age 55 or older by year-end can make an additional $1,000 catch-up contribution.
Key Traps and Nuances:- Prorated Contributions: Eligibility is determined monthly. If a client is eligible for only part of the year (e.g., they enroll in Medicare on July 1), their maximum contribution must be prorated.
- Employer Contributions: Any contribution made by an employer counts against the employee's annual limit. If an employer contributes $1,000 to an employee's family HSA, the employee can only contribute an additional $7,550 (for 2025).
- Disqualifying Coverage: General-purpose health insurance that is not an HDHP will disqualify a client. However, "permitted coverage" like standalone dental, vision, disability, or long-term care insurance does not disqualify them.
- Medicare Disqualification: Enrollment in any part of Medicare (A, B, C, or D) is disqualifying coverage. This is a hard rule and a frequent topic for exam questions. Once enrolled, a client can no longer contribute to an HSA, though they can still use existing funds.
The "Last-Month Rule": A Common Exam 'Gotcha'
The "last-month rule" is a special provision that allows a client who becomes HSA-eligible late in the year (specifically, on December 1st) to make the full year's contribution.
This benefit comes with a significant string attached: the client must remain HSA-eligible for the entire following calendar year, known as the "testing period." If they lose eligibility during this 13-month period (from December 1 of the contribution year through December 31 of the next year), the portion of the contribution that was only allowed due to the last-month rule becomes taxable income and is subject to a 10% penalty.

HSA vs. FSA: A Quick Comparison for the Exam
Examiners often test your ability to distinguish between HSAs and Flexible Spending Accounts (FSAs). Knowing these differences is crucial for making appropriate client recommendations.
| Feature | Health Savings Account (HSA) | Flexible Spending Account (FSA) |
|---|---|---|
| Eligibility | Must have a High-Deductible Health Plan (HDHP). | Offered by an employer; HDHP not required. |
| Ownership | Owned by the individual; fully portable. | Owned by the employer; not portable. |
| Contribution Limits (2025) | $4,300 (self) / $8,550 (family) + $1k catch-up. | $3,200 (set by IRS, employer can set lower). |
| Rollover | Funds roll over year after year without limit. | "Use-it-or-lose-it" rule applies (some plans allow limited carryover or grace period). |
| Tax Treatment | Triple Tax-Advantaged (deductible contributions, tax-free growth, tax-free withdrawals). | Double Tax-Advantaged (pre-tax contributions, tax-free withdrawals). |
Worked Example: Pro-Rata Contributions and Medicare
Let's walk through a realistic exam-style scenario. This will show how multiple rules intersect and where candidates make mistakes.
Scenario:David (age 64) and Maria (age 58) are married and have family HDHP coverage for all of 2025. On September 1, 2025, David turns 65 and is automatically enrolled in Medicare Part A. Maria remains on the family HDHP and is not enrolled in Medicare. For 2025, they incur $5,000 in qualified medical expenses.
Question: What is the maximum HSA contribution David and Maria can make for 2025? Step-by-Step Solution:- Determine the Eligibility Period:
- From January 1 to August 31 (8 months), both David and Maria were covered by a family HDHP and were not enrolled in Medicare. During this period, they were eligible to make contributions based on the family limit.
- On September 1, David's enrollment in Medicare Part A makes him ineligible to contribute to an HSA.
- Calculate the Prorated Family Contribution:
- The 2025 family contribution limit is $8,550.
- Maria, at age 58, is eligible for a $1,000 catch-up contribution. David is not yet 55 for HSA catch-up purposes (he is 64). Wait, David is 64, so he is over 55. He is eligible for a catch-up. Let me correct that. David (64) and Maria (58) are both over 55. So they are both eligible for the $1,000 catch-up.
- Total potential annual contribution: $8,550 (family) + $1,000 (David's catch-up) + $1,000 (Maria's catch-up) = $10,550.
- Prorated amount for 8 months of eligibility: ($10,550 / 12) * 8 = $7,033.33.
- Determine Eligibility for the Remainder of the Year:
- From September 1 to December 31 (4 months), David is ineligible.
- Maria is still covered by an HDHP and is not on Medicare, so she remains HSA-eligible.
- Crucial Rule: Because one member of the family plan (David) has disqualifying coverage, the family can no longer make "family" contributions. However, the eligible spouse (Maria) can make contributions up to the self-only limit, prorated for the rest of the year, into her own HSA.
- Calculate Maria's Prorated Self-Only Contribution:
- The 2025 self-only contribution limit is $4,300.
- Maria is eligible for her $1,000 catch-up.
- Total potential annual self-only contribution for Maria: $4,300 + $1,000 = $5,300.
- Prorated amount for the remaining 4 months: ($5,300 / 12) * 4 = $1,766.67.
- Calculate the Total Maximum Contribution for 2025:
- Total = Prorated Family Contribution + Maria's Prorated Self-Only Contribution
- Total = $7,033.33 + $1,766.67 = $8,800.
The most common wrong answer is to simply prorate the family contribution for 8 months ($7,033) and stop there. This misses the critical nuance that the eligible spouse, Maria, can continue contributing for the rest of the year at the self-only rate. The CFP Board tests this specific application of IRC § 223 to see if you can take the planning to the next level. Another error is forgetting to include both catch-up contributions in the initial calculation.

How Are HSA Distributions Taxed?
Distributions from an HSA are tax-free and penalty-free at any age, as long as they are used for qualified medical expenses as defined in IRC § 213(d). This includes medical, dental, and vision care, as well as prescription drugs.
- Non-Qualified Distributions (Under Age 65): If funds are withdrawn for non-medical reasons before age 65, the amount is included in gross income and subject to a 20% penalty.
- Non-Qualified Distributions (Age 65+): After age 65, the 20% penalty is waived. The withdrawn amount is still subject to ordinary income tax, effectively making the HSA function like a traditional IRA for non-medical withdrawals in retirement.
- Excess Contributions: Contributions above the annual limit that are not corrected are subject to a 6% excise tax for each year they remain in the account.
Frequently asked questions
How many HSA questions are on the CFP exam?
The CFP Board does not publish question counts for specific topics. Expect several questions on HSAs, typically integrated into larger case scenarios testing Insurance, Tax, and Retirement Planning knowledge areas.What is the best way to study for HSA questions?
Focus on application, not just memorization. Work through practice questions that involve mid-year eligibility changes, Medicare enrollment, and employer contributions. Understanding the "why" behind the rules is key.Can HSA funds be invested?
Yes. Similar to an IRA, HSA funds can be invested in stocks, bonds, and mutual funds once the account balance reaches a certain threshold (set by the custodian). This is why HSAs are considered powerful retirement savings vehicles.What happens to an HSA upon the account owner's death?
If the surviving spouse is the designated beneficiary, the HSA is treated as their own. If the beneficiary is not a spouse, the HSA ceases to be an HSA, and the fair market value becomes taxable to the beneficiary in the year of death.---
