Tax-Advantaged Accounts for Health Care Expenses: Side-by-Side Comparison 
 
Summary 
Four types of tax-advantaged accounts can be used to pay for unreimbursed medical expenses: 
health care Flexible Spending Accounts (FSAs), Health Reimbursement Accounts (HRAs), 
Health Savings Accounts (HSAs), and Medical Savings Accounts (MSAs). Unreimbursed 
medical expenses typically include deductibles, copayments, and goods and/or services not 
covered by insurance. Although these accounts share some common features, they also differ in 
important respects. 
This report provides brief summaries of the four accounts and compares them with respect to 
eligibility, contribution limits, use of funds, and other characteristics for tax year 2010. The report 
then discusses changes to the accounts resulting from the enactment of the Patient Protection and 
Affordable Care Act (P.L. 111-148 as amended). The final section of the report covers 
participation levels in these accounts. The report will be updated when relevant statutory or 
regulatory changes occur, when new data become available, and as Congress considers issues 
associated with these accounts.

Tax-Advantaged Accounts for Health Care Expenses: Side-by-Side Comparison 
 
Introduction 
Four types of tax-advantaged accounts can be used to pay for unreimbursed medical expenses: 
health care Flexible Spending Accounts (FSAs), Health Reimbursement Accounts (HRAs), 
Health Savings Accounts (HSAs), and Medical Savings Accounts (MSAs).1 Unreimbursed 
medical expenses typically include deductibles, copayments, and goods and/or services not 
covered by insurance.2 The first part of this report describes the current law surrounding these 
accounts and provides a side-by-side comparison of their key features. The second section details 
changes to the accounts effective over the next two years that were enacted by the Patient 
Protection and Affordable Care Act (P.L. 111-148 as amended). The third section investigates the 
participation rates in each account type. The report will be updated when relevant statutory or 
regulatory changes occur, when new data become available, and as Congress considers issues 
associated with these accounts. 
Current Law 
The text in this section provides summaries of each account as of June 2010. Although the 
accounts differ in many ways, they each provide tax savings to the account holders. Table 1 
provides a more detailed side-by-side comparison of the laws and regulations governing each 
account. 
Flexible Spending Accounts 
FSAs are employer-established arrangements that reimburse employees for medical and dental 
expenses not covered by insurance or otherwise reimbursable.3 They are usually funded through 
salary reduction agreements under which employees receive lower monetary wages in exchange 
for equivalent contributions to their flexible spending accounts. For example, employees may 
forgo $100 a month in their 2010 paychecks in exchange for a $1,200 annual contribution to their 
FSA. Employees choose how much to put into their accounts, and this amount can vary from year 
to year. Employees forfeit unused balances at the end of the year unless the employer offers a 
grace period for additional claims of up to 2½ months after the end of the year (e.g., so medical 
expenses incurred by March 15, 2011, could be reimbursed from the FSA for 2010). The entire 
annual amount of an FSA must be made available to employees at the beginning of the year. 
While compensation received as wages is subject to income taxes, as well as Social Security and 
Medicare taxes, compensation received as FSA contributions is not subject to these taxes. (Social 
Security and Medicare together are known as employment taxes.) For this reason, employees who 
anticipate having health expenses not covered by insurance may prefer FSAs over monetary 
wages.

Tax-Advantaged Accounts for Health Care Expenses: Side-by-Side Comparison 
 
FSAs funded by salary reductions are governed by Section 125 of the Internal Revenue Code, 
which exempts contributions from taxes despite the fact that employees have the choice to receive 
taxable wages.4 Most rules regarding FSAs are not spelled out in the Code; they were initially 
included in proposed regulations issued by the Internal Revenue Service (IRS) in 1984 and 1989, 
and have been subsequently modified.5  
Health Reimbursement Accounts  
HRAs are employer-established arrangements to reimburse employees for medical and dental 
expenses not covered by insurance or otherwise reimbursable. As is the case with FSAs, 
contributions are subject to neither income nor employment taxes. However, contributions cannot 
be made through the employees’ salary reduction agreements; only employers may contribute. In 
addition, funds must be used for qualified medical expenses as defined by the IRC. Employers 
may restrict the types of medical and health services that are eligible for reimbursement. For 
example, an employer may choose not to reimburse expenses associated with acupuncture 
treatments. Unlike FSAs, employers need not actually fund HRAs until employees draw upon 
them. Also unlike FSAs, reimbursements can be limited to amounts previously contributed. 
Unused balances may be carried over indefinitely, though employers may limit the aggregate 
carryovers.  
HRAs are governed by Section 105 of the Internal Revenue Code, which allows health plan 
benefits used for medical care to be exempt from taxes, and Section 106 of the Code, which 
allows employer contributions to those plans to be tax-exempt. Rules regarding HRAs are spelled 
out in IRS revenue rulings and notices issued in 2002.6 
Health Savings Accounts 
HSAs are tax-exempt accounts that are used to pay for medical and dental expenses not covered 
by insurance or otherwise reimbursable. Unlike the FSAs and MSAs (discussed below), they are 
established by individuals with an insurance plan meeting certain criteria. An individual may 
purchase an HSA-qualified insurance plan through the individual insurance market. For those 
individuals with employer-sponsored insurance, the employer must offer a HSA-qualified plan in 
the small group or large group insurance market. 
To be HSA-qualified, the insurance plan must be a high-deductible health plan (HDHP). The 
required level of deductible varies over time with the cost of living. In 2010, a HDHP is defined 
as one with a deductible of at least $1,200 for self-only coverage and $2,400 for family coverage. 
There are other criteria, including that the plan holder have no other health insurance policy, with 
some exceptions. 
                                                             
4 Section 125 governs cafeteria plans; it provides an express exception to the constructive receipt rule, which requires 
taxation of what is normally nontaxable income when taxpayers have the choice of receiving taxable income or 
nontaxable income.

Tax-Advantaged Accounts for Health Care Expenses: Side-by-Side Comparison 
 
In 2010, HSA contributions are limited to $3,050 for self-only coverage and $6,150 for family 
coverage. An additional contribution of $1,000 is allowed people aged 55 and older. HSA holders 
cannot contribute to their account in any year where they do not have qualifying HDHPs. On the 
other hand, HSA holders can draw funds for their accounts even if they are not permitted to 
contribute. 
HSAs carry significant tax advantages. Contributions made by employers are exempt from 
income and employment taxes. Account owners may deduct contributions they make from 
adjusted gross income.7 Owners do not have to itemize deductions to take advantage of this tax 
credit. Withdrawals for medical expenses are not taxed; those used for any non-medical purpose 
are taxable and subject to a 10% penalty except in cases of disability, death, or attaining age 65. 
Unused balances may be carried over from year to year without limit. 
HSAs were first authorized by the Medicare Prescription Drug, Improvement, and Modernization 
Act of 2003 (MMA, P.L. 108-173). Most statutory rules are in Section 223 of the Internal 
Revenue Code. The Treasury Department provides revenue guidance as well.8 
Medical Savings Accounts 
MSAs, also known as Archer MSAs,9 are a precursor to HSAs.10 Like HSAs, MSAs can be 
established and contributions made only when insurance plan holders have a HDHP and no other 
coverage, with some exceptions. Contributions made by employers are exempt from income and 
employment taxes. Contributions made by account owners (allowed only if the employer does not 
contribute) are deductible for income-tax purposes even if the account owner does not itemize 
medical deductions. Withdrawals are not taxed if used for medical expenses; those used for non-
medical purposes are taxable and generally subject to an additional 15% penalty. Unused balances 
may be carried over from year to year without limit. 
The principal difference between HSAs and MSAs is that MSA eligibility is limited to people 
who are self-employed or employed by a small employer (50 or fewer employees, on average). In 
addition, the minimum deductible levels are higher and the contribution limits are lower. 
MSAs were first authorized by the Health Insurance Portability and Accountability Act of 1996 
(P.L. 104-191). The legislation limited the total number of accounts to 750,000, with a few MSAs 
excluded from that total. Most statutory rules governing MSAs are in Section 220 of the Internal 
Revenue Code. 
                                                             
7 Adjusted gross income is total income less income that is not subject to tax less certain business deductions. 
Contributions to HSAs are considered income that is not subject to tax.

Tax-Advantaged Accounts for Health Care Expenses: Side-by-Side Comparison 
 
Patient Protection and Affordable Care Act (PPACA) 
Changes to Tax-Advantaged Accounts 
The Patient Protection and Affordable Care Act (PPACA, P.L. 111-148), as amended by the 
Health Care and Education Reconciliation Act of 2010 (P.L. 111-152), imposes various 
restrictions on the accounts.11 One set of changes makes three of the savings accounts more 
compatible with the existing Internal Revenue Code (IRC) requirements covering what can be 
itemized for those who do take deductions for medical expenses.12 Under current law, over-the-
counter (OTC) medications (except insulin) cannot be included in itemized deductions unless 
they are prescribed by a physician. However, under current law, OTC medications can by funded 
through FSA, HSA, or MSA accounts. Starting in 2011, PPACA will prohibit using funds from 
FSA, HSA, and MSA accounts for OTC medications (except insulin) unless they are prescribed 
by a physician.13 
The second change concerns limits on the FSA contribution. No statutory limits on the amount an 
employee can contribute to a FSA existed prior to PPACA. Instead, individual employers often 
imposed their own limits. Beginning in 2013, PPACA will limit the annual amount an employee 
can contribute to $2,500. 
The final change is that PPACA, effective in 2011, increases the penalties imposed for account 
withdrawals for nonmedical purposes for those under age 65 in two accounts The penalty for 
nonmedical withdrawals from HSAs will increase to 20% from 10%. The penalty for nonmedical 
withdrawals from MSAs will increase to 20% from 15%. 
Participation in the Tax-Advantaged Accounts 
Measuring total participation in the four tax-advantaged accounts is difficult because of a lack of 
reliable and timely data. The Department of Labor (Bureau of Labor Statistics) and the Treasury 
Department (IRS), a few research organizations, and several human resources private-sector 
consulting firms measure various concepts of account participation. To use HSAs as an example, 
measures of total HSA participation include  
•  the number of individuals (adults and children) whose medical expenses can be 
funded through an HSA because they are covered by a HSA-eligible HDHP; 
•  the number of employees who chose a HSA-eligible, employer-provided 
insurance plan and go on to actually open an HAS; 
•  the number of tax-filing household units who take the HSA deduction; and 
                                                             
11 For more information on this issue, see CRS Report R41128, Health-Related Revenue Provisions in the Patient 
Protection and Affordable Care Act (PPACA) , by Janemarie Mulvey. 
12 This is the deduction currently taken when qualified medical expenses exceed 7.5% of adjusted gross income. 
13 In the past, the IRS has defined a drug as prescribed if its purchase requires a prescription. For example, aspirin 
would not be eligible for reimbursement even when recommended by a physician because its purchase does not require 
a prescription. For more information, see Internal Revenue Service, Medical and Dental Expenses, November 10, 2009.

Tax-Advantaged Accounts for Health Care Expenses: Side-by-Side Comparison 
 
•  the number of individuals or households in a sample who report having an HSA 
when asked by an interviewer, with those numbers statistically adjusted to 
represent the number in the population as a whole. 
These concepts are neither the “correct” nor “incorrect” measures of HSA participation. Rather, 
they are simply measures of different ideas. The various concepts have different strengths and 
weaknesses as measures. Nevertheless, a primary criteria for reporting data on the four savings 
accounts is to use ideas that are comparable across all accounts. 
Unfortunately, there does not appear to be a participation measure available for all four accounts. 
Instead, CRS reports one accurate measure for two accounts. Because all individuals with a HSA 
or a MSA can claim deductions on their tax returns, the IRS maintains data on the number of tax 
returns with these deductions. Figure 1 presents the number of returns that filed for a HSA 
deduction and that filed for a MSA deduction.  
Using tax returns as the unit of HSA and MSA measurement has at least three disadvantages. 
First, each return could represent an individual, a married couple, or a family. Second, the number 
of adults and children eligible to use funds in each HSA is unknown. Third, the most recent 
available data cover 2008, while other data sources have 2009 data available. Nevertheless, there 
is no other source with which CRS is familiar that allows for a comparison of these two accounts.

Tax-Advantaged Accounts for Health Care Expenses: Side-by-Side Comparison 
 
In every year since 2004, the number of returns with an HSA deduction far exceeded the number 
of returns with an MSA deduction. Moreover, the number of HSA returns increase rapidly since 
their inception in 2004, while the number of MSA returns declined rapidly. 
Similar IRS participation data do not exist for FSAs and HRAs, which are available only through 
employer-sponsored health insurance coverage and are not enumerated on an individual’s income 
tax return. One survey of employers found that between 2% and 3% of the workers covered by 
health insurance enrolled in an HRA between 2006 and 2009.14 CRS has not found a comparable 
percentage of workers covered by health insurance who were enrolled in a FSA.
