Title 22 CCR §50549.2 says:

There shall be a deduction of $20 from the combined nonexempt unearned income of all aged, blind, or disabled MN persons and the spouse or parents of these persons.

If two aged, blind or disabled persons in the same MFBU each receives unearned income, such as two spouses who both receive Social Security benefits, the county should only allow one $20 deduction in computing the share of cost for the MFBU. However, if the MFBU is divided into multiple Mini-Budget Units (MBUs), each MBU may receive its own $20 unearned deduction.
