5statutes; relating to: creating a nonrefundable individual income tax credit for
6certain taxpayers and a new top individual income tax bracket.
Analysis by the Legislative Reference Bureau
This bill creates a nonrefundable individual income tax credit for taxpayers
with Wisconsin taxable income (WTI) below certain income thresholds. The credit
phases out for taxpayers with WTI above these thresholds. Income thresholds and
phase-out rates vary by filing status as follows:
1. For an individual who files as a single individual or head of household, the
maximum credit amount is $200 if the claimant's WTI in the year to which the claim
relates is less than $75,000. The maximum credit phases out from $200 to zero as
the claimant's WTI increases from $75,000 to $112,500.
2. For a married couple that files a joint return, the maximum credit amount
is $200 if the sum of the claimant's WTI and his or her spouse's WTI in the year to
which the claim relates is less than $100,000. The maximum credit phases out from
$200 to zero as the couple's household WTI increases from $100,000 to $150,000. For
a married couple that files separately, the maximum credit amount is $100 if the

claimant's WTI in the year to which the claim relates is less than $50,000. The
maximum credit phases out from $100 to zero as the claimant's WTI increases from
$50,000 to $75,000. Generally, both spouses of a married couple may claim the credit
if they file separate returns.
Because the credit is nonrefundable, no refund is paid if the amount of the
credit exceeds the taxpayer's tax liability. Part-year and nonresidents of this state
may not claim the credit.
The bill also creates a fifth individual income tax bracket and a new tax rate
for this bracket. For those who file as a single individual, fiduciary, or head of
household, the new top rate is 8.88 percent on taxable income above $750,000. For
married joint filers, the new 8.88 percent rate applies to taxable income above
$1,000,000, and this new rate applies to married separate filers on taxable income
above $500,000. As is the case under the current law brackets, the new bracket
amounts are indexed for inflation.
The bill first applies to taxable years beginning on January 1, 2017.
For further information see the state fiscal estimate, which will be printed as
an appendix to this bill.
