AB402,1,3 1An Act to create 71.07 (6e) and 71.10 (4) (ce) of the statutes; relating to:
2creating a nonrefundable individual income tax credit for certain amounts of
3taxable social security benefits.
Analysis by the Legislative Reference Bureau
In general, under current law, 50 percent of certain social security benefits are
taxed by this state once the recipient's income reaches $34,000 for a single individual
or $44,000 for a married couple filing jointly, while the federal government taxes 85
percent of these same benefits. The remaining 50 percent of such benefits that are
not taxed by this state are exempt from taxation.
This bill creates a nonrefundable individual income tax credit for taxable
amounts of social security benefits. Over the course of five years, beginning with
2006, the bill phases in the credit. The credit amount is calculated to be the amount
of a claimant's taxable social security benefits that he or she receives in the year to
which the claim relates, multiplied by the taxpayer's marginal tax rate. In 2006, this
amount is then multiplied by 20 percent; in 2007, by 40 percent; in 2008, 60 percent;
in 2009, 80 percent; and in 2010 and thereafter, by 100 percent.
For further information see the state fiscal estimate, which will be printed as
an appendix to this bill.
The people of the state of Wisconsin, represented in senate and assembly, do
