Tax Credits and the Affordability of Individual Health Insurance
Issue Brief No. 53
s federal policy makers explore using tax credits to help uninsured Americans buy individual health insurance, a key question is whether the credits are large enough to make insurance affordable for those who are older or in less-than-perfect health. A Center for Studying Health System Change (HSC) analysis of two leading proposalsone by President Bush and the other by a bipartisan group of senatorsindicates tax credits would make individual coverage affordable for many people but are unlikely to offer much help to those who are older or in imperfect health. For example, nine out of 10 19- to 29-year-olds in excellent health would receive credits covering at least half of the estimated cost of an individual policy, compared with only one in 100 people age 55-64 in poor health.
Understanding the Individual Insurance Market
n 2000-01, slightly more than 30 million people under the age of 65 were uninsured and did not have access to employer-sponsored insurance.1 Recent proposals seek to encourage people without access to employer-sponsored insurance and who are ineligible for public insurance programs to buy individual, or non-group, insurance by offering income-related tax credits to reduce the cost of insurance (see box). Currently, only 10.3 million Americans, or 5 percent of the nonelderly insured population, have individual insurance.
A key policy question is whether proposed tax credits are large enough to make individual insurance affordable for older people or people in less- than-perfect health, many of whom are either priced out or shut out of the current individual insurance market. The answer depends on how much it costs to buy individual insurance for those eligible for tax credits. Even large tax credits may be insufficient to make insurance affordable for those facing the highest premiums because of their age or health.2
Determining the cost of individual insurance is complicated because of the prevalence of medical underwriting in the individual market.3 Some argue that people with preexisting medical conditions may be unable to obtain any offers of insurance or, if they do, the price is unaffordable or the coverage excludes care for their conditions.4 Others maintain that actual experience with individual insurance indicates relatively little medical underwriting, that costs are not very sensitive to differences in peoples health conditions and that decisions to purchase coverage are not strongly related to health.5
HSC analyzed the cost of individual insurance using premiums reported by people nationwide in the Community Tracking Study (CTS) Household Survey in 1996-97 and 1998-99 (see Data Source and Methods). Estimated individual insurance premiums for a single person increase with both advancing age and declining health. For example:
In 1998-99, 6 million uninsured nonelderly adults reported their health as either fair or poor. Another 7.5 million uninsured people in good or excellent health reported having at least one health condition that could lead to higher prices or coverage exclusions in the individual market.
How Far Can Tax Credits Reach?
o analyze the potential impact of proposed tax credits on the individual market, HSC identified people likely to qualify for a credit based on their current insurance coverage and income.9 An analysis of CTS data suggests that an estimated 28.6 million people without access to employer-sponsored or public insurance would be eligible to receive a credit under the REACH proposal. Most (88%) of these people, or 25.2 million, also would receive a credit under the Bush plan. About 80 percent of those eligible for a credit under either plan are uninsured (the remaining 20 percent already have individual insurance coverage).
Looking only at the uninsured, the REACH bill would provide a larger average credit per family: $1,535, compared with $1,155 for the Bush plan. Consequently, the REACH proposal would provide a larger average subsidy of the estimated premium for individual insurance: 54 percent, compared with 43 percent for the Bush plan.
Even if the credit provides a substantial reduction in what consumers pay for insurance, the after-credit premium still needs to be affordable to induce people to purchase coverage. While the relationship among income, price, subsidy percentage and the decision to purchase insurance is complex, a useful yardstick for measuring affordability is the premium as a percentage of family income. Based on CTS data for people who currently own individual insurance policies, about half spend 8 percent or less of their income for coverage, and about three-quarters pay less than 16 percent of their income.
To gauge whether people would be more or less likely to buy coverage with a tax credit, HSC simulated the proportions of people who would be:
Without a tax credit, uninsured people would spend an average of 25 percent of their income to buy individual coverage. The Bush proposal would drop that average to 16 percent; the REACH plan would lower it further to 14 percent.
Under both proposals, substantial numbers of people would receive credits covering 50 percent or more of the cost of individual insurance and, as a consequence, would face post-credit insurance costs of less than 8 percent of income. The REACH proposal is more generous. It provides larger subsidiesmore than 50 percent of the cost of insuranceto more people and shifts more people into the affordable range, or a post-credit premium of less than 8 percent of income. Under REACH, the tax credit would cover at least half of the cost of individual insurance for 58 percent of uninsured people presumed eligible for a credit, compared with 31 percent of uninsured people under the Bush plan (see Figure 1).
Without tax credits, only 18 percent of uninsured eligibles are estimated to face insurance costs of less than 8 percent of family income, and even with this arguably affordable cost, these people remain uninsured. Both tax credit proposals increase the proportion of uninsured people who would fall into the affordable range: 53 percent under REACH and 44 percent under the Bush proposal, although 22 percent to 26 percent would still face post-credit premiums amounting to more than 16 percent of their incomes plan (see Figure 2).
Less Help for Those Most in Need
oth proposals would provide significant help to a substantial number of people. But both are also limited in how much they can help those who are older, are in poorer health or have very low incomes. Even under the more generous REACH proposal, only 22 percent of the poorest people would face post-credit premiums in the affordable range, compared with more than two-thirds of those with family incomes above poverty. More than four times as many of the poorest people would still face premiums exceeding 16 percent of their incomes46 percent of the poorest, compared with 10 to 12 percent of the nonpoor (see Table 1).
Post-credit premiums also become much less affordable as peoples health worsens or they grow older. Almost two-thirds of people in poor health would still have to pay more than 16 percent of their incomes, compared with only 12 percent of people in excellent health. Similarly, 43 percent of people 55-64 would still find premiums unaffordable, compared with 15 percent of 19- to 29-year-olds.
The combined effects of age and health create wide variations in the degree of assistance tax credits would provide toward purchasing individual coverage. For example:
his analysis suggests that tax credits based only on income and family size will fail to help many in greatest need of coverage. Structuring a tax credit to vary with the ages of the recipients, as well as with income and family size, would help uninsured people in poorer health to purchase health insurance, because health tends to decline with age and insurance premiums are known to vary with age. Basing the size of the credit on income relative to the poverty line and providing larger credits than under the current proposals for those below poverty could improve affordability for the very poor.
Adjusting tax credits for variations in health is a much more complex and challenging task. Roughly 6 million uninsured people are currently in fair or poor health, and another 7.5 million are in good health but have one or more potentially chronic health conditions. Many of these people might not be able to buy an individual insurance policy at any price, so an alternative approach that complements a tax credit may be needed.
One option is to build on the experiences of state high-risk pools, using a decentralized network of administrative offices to screen applicants health conditions. 10 The tax credit amount might be increased for people who qualify for high-risk pools, since premiums charged by the pools can be high. 11 If variations in the availability and structure of high-risk pools across states are viewed as inequitable, then a national pool or a joint federal-state approach could be evaluated.
Policy makers also might consider restructuring the individual insurance market. Concerns about potential adverse effects on market structure of regulatory requirements such as guaranteed issue, guaranteed renewal and medical-underwriting restrictions may be alleviated if tax credits expand the size of the individual insurance market by attracting large numbers of relatively healthy people.
Another option is reinsurance of individual policies or after-the-fact compensation of insurers for people who have very large medical expenses. The cost of insurance for these people would be spread over a potentially much larger pool or be publicly funded, depending on the specific mechanism used. For example, New Yorks Healthy New York program includes a reinsurance mechanism.12
Finally, many people with very low incomes may be eligible for existing public insurance programssuggesting that more may need to be done to enroll them. For others, such as adults without children or people in states with very low income-eligibility thresholds for covering otherwise eligible adults, expanding public insurance eligibility or allowing credits to be used to buy into existing public insurance programs might be considered.
Making Health Insurance More Affordable: Two Tax-Credit Proposals
Data Source and Methods
his Issue Brief presents findings from HSCs Community Tracking Study Household Survey conducted in 1996-97 and 1998-99. That survey is a nationally representative telephone survey of the civilian, noninstitutionalized population, supplemented by in-person interviews of households without telephones to ensure proper representation. Each round of the survey contains information on about 60,000 people, and the response rates ranged from 60 percent to 65 percent.
The cost of individual insurance calculated for this Issue Brief used premium data from almost 2,500 policies reported by survey respondents. The analysis is based on estimates of the cost of individual insurance projected to the entire population potentially eligible to receive tax credits. The premium estimates are adjusted for the fact that people who actually buy such policies may be in significantly better health than those who do not.6 Without making this adjustment, actual premiums paid by people currently in the individual insurance market are not good indicators of what it would cost other people to buy individual policies.
