all i can find is
BASIC STAR is available on a homeowner’s primary
residence only, and for households with an income
of less than $500,000. Homeowners need apply only
one time* for BASIC STAR, and it remains in effect
until ownership of the home changes. However, the
exemption amount is calculated each year, and the
actual tax savings may change annually
