2.3 Modified Adjusted Gross Income Test Groups

BadgerCare Plus eligibility determinations use Modified Adjusting Gross Income (MAGI) rules. MAGIModified Adjusted Gross Income. MAGI rules are used to determine BadgerCare Plus eligibility for new applicants beginning in 2014 and for existing members as of March 31, 2014, or their next regularly scheduled renewal, whichever is later.

All MAGI groups are based on a “target” person. Each person who can become eligible for BadgerCare Plus on the application will be a target during the eligibility determination for a case.

2.3.1.1 Tax Filers

If the person is a tax filer and is not being claimed as a dependent by anyone else, then the person’s MAGI group consists of the tax filer, the tax filer’s spouse, and any dependents the tax filer is claiming.

If there is a pregnant woman in the group, include the number of expected babies in the group size. Verification of the number of expected babies is not required unless questionable. If the number of babies is unknown, add one to the group size.

In general, a person cannot be claimed as a tax dependent unless that person is a U.S. citizen, U.S. resident alien, U.S. national, or a resident of Canada or Mexico.

Out-of-the-Home Tax Dependents

A tax filer is able to claim individuals who live outside of their home as their tax dependents. Common examples include college students and other adult children, elderly parents, or siblings who do not live with the filer(s). Tax filers can also claim a deceased child as their tax dependent in the year that the child has died. In these instances, the deceased child would be included in the tax filer’s group size, though the child would not be eligible for benefits on that application.

Deceased Co-Filers

It is possible for a person to file their taxes jointly with a deceased spouse for the taxable year in which the spouse died. As of February 1, 2014, the deceased co-filer should be added to assistance groups according to MAGIModified Adjusted Gross Income.

Married Couples

Married individuals who are living together are always included in each other’s group size, even if they are filing taxes separately. If a married couple is living apart but filing jointly, the couple is included in each other’s group size. If the married couple is living apart and filing taxes separately, or are not planning to file taxes, do not include them in each other’s group size.
