How the Tax Law Encourages Third-Party Insurance and Penalizes Individual Self-Insurance
|
One strange feature of the tax code is that a physician's fee paid by an
employer (or an employer's insurance carrier) is paid with pretax dollars,
whereas fees paid out-of-pocket by employees must be paid with aftertax
dollars. As a result, the tax law encourages (subsidizes) 100 percent health
insurance coverage (with no deductibles and no copayments) for all medical
expenses.
Federal tax law has an enormous impact on employee benefit plans because
individual marginal tax rates are so high. Even a moderate wage earner in
the U.S. economy gets to keep less than 70 cents out of each additional
dollar earned. As Table I shows:
- For an employee facing an income tax rate of 15 percent and a combined
(employer plus employee) Social Security tax rate of 15.3 percent, federal
taxes take 30.3 cents out of each additional dollar of wages.
- If the employee faces a 6 percent state and local income tax, the
marginal tax rate is 36.3 percent, leaving the employee with less than two-thirds
of a dollar of wages in the form of take-home pay.
The results are even worse for employees in higher tax brackets:
- Workers in the 28 percent federal income tax bracket face a marginal
tax rate of 43.3 percent - leaving them with less than 57 cents in take-home
pay out of each additional dollar of earnings.
- If state and local income taxes apply, these workers take home only
51 cents of each additional dollar of earnings.
Because wages are taxed and health insurance benefits are not, health insurance
is more valuable to employees than additional wages. As Table II shows: 6
- For an employee in the 15 percent tax bracket (and facing a 15.3 percent
FICA tax), federal tax law makes $1.44 of health insurance benefits equivalent
to a dollar of take-home pay - because $1.44 in gross wages will be reduced
by 44 cents in taxes.
- For an employee who is in the 28 percent bracket, $1.76 of health
insurance benefits is equivalent to a dollar of take-home pay.
- For a higher-paid employee also facing a 6 percent state and local
income tax rate, $1.97 of health insurance benefits is equivalent to a dollar
of take-home pay.
Table II also shows how much waste can be present in the purchase of health
insurance and still allow health insurance to be preferable to wages. [See
Figure II.] For example, if an employer attempted to give the higher-paid
employee $1.97 in wages, the employee's take-home pay would be only $1.00
after taxes are paid. As a result:
- For a highly paid employee, $1.97 spent on health insurance need only
be worth $1.01 to be preferable to $1.97 of gross wages.
- Thus, 96 cents of $1.97 (or 49 percent of the premium) can represent
pure waste and still leave health insurance preferable to wages for the
employee.
This is why employees tend to prefer generous (and wasteful) health insurance
coverage - coverage that they would not buy out-of-pocket without tax subsidies.
Note also that the higher the tax bracket, the greater the economic incentive
to purchase more health insurance. Higher-paid workers tend to dictate the
contents of employee benefit plans and impose their choices on all other
workers. Moreover, many current employee benefit plans were shaped decades
ago, when marginal tax rates were much higher and the incentives for waste
even greater.
The total tax deduction for employer-provided health insurance is about
$60 billion per year - roughly $600 for every American family. Although
this system may appear to benefit large companies with more generous employee
benefits, in many cases these companies are trapped by benefit plans that
are eating into company profits, raising production costs and keeping wages
lower than they otherwise would be. The current system not only encourages
and subsidizes rising health care costs, it also harms the very industries
and companies which are subsidized the most.
