Let me preface this by saying I am not a lawyer. Looking at this link to the requirements for small and micro-entity status shows two ways to qualify for micro-entity status.
Micro entity: There are two ways to qualify as a micro-entity.
first way is under paragraph (a) of the new rule, requiring the
following conditions that must be satisfied individually for each
applicant, inventor, and joint inventor who:
- has not been named as
an inventor on more than 4 prior patent applications (provisional
applications, patent applications filed in a foreign country, PCT
international applications for which the basic US national fee was not
paid, and applications that a party has assigned or is under an
obligation to assign as a result of previous employment do not count);
has gross income less than 3 times the median household income in
the U.S. for the preceding calendar year (for 2013 fees = $150,162, or
3X$50,054, the 2012 median household income. For parties not paid in
US dollars, the average currency exchange rate during the previous
calendar year applies.);
has not assigned, licensed or otherwise
granted an interest in the invention to an entity who has gross income
more than the amount listed above (unless the entity relates to an
institution of higher education); and
also meets the requirement for
small entity status.
The second way, under paragraph (d) of the new
rule, is by having a relationship with a U.S. institution of higher
education. The applicant’s employer, from which the applicant obtains
the majority of the applicant’s income, must be an institution of
higher education. Or, the application must be assigned, granted,
conveyed, or is under and obligation of contract or law to assign,
grant, or convey, a license ownership interest in the particular
application to the institution of higher education.
Thus, I believe the linked form is just covering the gross income requirement of the first option for qualification. The linked website doesn't make clear that the there are two options. You need only qualify for one option or the other. Since I am not a lawyer, I would suggest reading the requirements carefully and if you feel you need additional clarification perhaps seek the advice of a qualified attorney.
