When one member of a couple works, only that member is eligible for 1619(b). The other
member is ineligible for payment due to deemed income, not his/her own income; therefore,
that member is not eligible for 1619(b). When both members work and they are ineligible
for payment due to a combination of earned income and deemed income, then each person
is separately eligible for 1619(b). Perform the threshold calculation on each person's
income. If one person's income is over the charted threshold, perform the individualized
calculation on that person only.
