By applying the KISS principle, Affordable-Care-Act subsidies, also known as premium tax credits, can be easily
understood, easily calculated, and easily obtained. KISS is the acronym for Keep it Simple, Stupid. The expression
was reportedly coined by Kelly Johnson, a lead engineer at Lockheed Shunk Works and has been used by many authors
for decades. It was a slogan and apparently one of the driving forces behind the success of the late Vince
Lombardi, legendary Hall-of-Fame coach of the Green Bay Packers.
Simply stated, a premium tax credit is a percentage of one’s health insurance premium paid by the federal
government for the purchase of Obamacare health insurance by low income and middle income individuals and families.
It is predicated on the premise that no household should have to spend more than a specified percentage of its
income on health insurance premiums. To be eligible for the credit beginning in 2014 individual or household
incomes must fall between less than 133% and 400% of the federal poverty level. The premium tax credit or subsidy
paid by the government is the difference between the cost of the second cheapest silver-level insurance plan in a
given state (known as the benchmark plan) and the percentage of the premium which the enrollee is responsible for
based on where the enrollee’s income ranks on the federal poverty level scale.
Individual responsibility for premium costs based on income level as a percentage of the federal poverty level is
|Income Level as Percentage of Federal Poverty Level
||Premium Costs as a Percentage of Income in 2014
| Less than 133%
At least 133% but less than 150%
| At least 150% but less than 200%
At least 200% but less than 250%
At least 250% less than 300%
At 300% but less than 400%
The federal poverty level of a household’s income varies depending on the size of the household, and the cost of
benchmark insurance plans vary from state to state, but the formula used to calculate tax subsidies is uniform and
is as follows: Tax subsidy or premium tax credit = (the cost of the second-lowest-price silver plan) minus (x% of
income). If for example a five-member household with an income of $82,710 which is at the 300% federal poverty
level, purchases a benchmark silver-level health insurance policy with an annual cost of $13,000, the annual
subsidy would be $13,000 - ($82,710 x 9.5%). ($82,710 x 9.5%) = $7857.45. Therefore the final calculation is
$13,000 - $7857.45 = $5142.55. This annual subsidy of $5142.55 divided by 12 equals a monthly subsidy of
Rather than going through this manual calculation however, the KISS principle can be applied by accessing the
premium tax calculator on the website of the federal health insurance exchange or the private health exchange
alternative if there are login problems with the federal one. In using the calculator to determine eligibility for
a premium tax credit in 2014, it will be necessary to enter the number of individuals including yourself, which you
will be claiming on your 2014 income tax return, your estimated household income for 2014, the number of people in
the household who will be applying for the subsidy, your zip code, county of residence, and your date of birth.
If the calculation shows that you are eligible for a subsidy, it will be applied to the plan that you purchase at
the time through the health insurance exchange, and will show up as a monthly premium discount adjustment from that
plan. Using the above example, if you select the benchmark plan which costs $1300 per month, your monthly premium
would be $1300 minus the $654.79 subsidy, or $645.21. Although the subsidy is based on the second lowest cost
silver-level plan in your state, you do have the option of purchasing a higher level plan and paying a higher
premium or a lower level plan and saving more since the actual subsidy will be the same.
