Wisconsin State Retirement Benefits - May 1, 2018 Increase

ADJUSTMENT ... In March, Wisconsin Employee Trust Funds announced the increase or decrease in pension benefits for retired state workers.  The annual adjustment takes place on May 1 of every year, but it’s helpful for preparers to know the amounts ahead of time to help the taxpayer adjust their withholding or estimated payments for 2018.

The ACTUAL adjustments beginning May 2018:
 FIXED/CORE: + 2.4% (increase)
 VARIABLE:     + 17.0% (increase)

SHORTCUT ... Once again, for estimate purposes, we have calculated a “shortcut method” to easily compute the total retirement benefit for the entire year, which includes the first 4 months and the higher amounts for the remaining 8 months.

D.A.T. Publisher's Shortcut Method for 2018:
Current (Jan, Feb, Mar, Apr) gross monthly annuity amount ...
(Note: keep in mind that this computation is based on the annuity amount received BEFORE the change in May!)

     Current Monthly FIXED  x 12.192 = Total Fixed for the entire year
     Current Monthly VARIABLE x 13.36 = Total Variable for the entire year (corrected March 22)


Example as PROOF ...

Suppose Judy's gross monthly annuity for March 2018 is
         $1,000 for fixed and
         $1,000 for variable. 

$1,000 fixed x 12.192 = $12,192
   (1st 4 months at $1,000/mo = $4,000)
   (Last 8 months at $1,024/mo = $8,192)
           ($1,024 reflects monthly increase by 2.4%)

$1,000 variable x 13.36 = $13,360
   (1st 4 months at $1,000/mo = $4,000)
   (Last 8 months at $1,170/mo = $9,360)
           ($1,170 reflects monthly increase by 17%)

Judy's total fixed amount for 2018 will be $12,192

Judy's total variable amount for 2018 will be $13,360

    How much income is required to meet the “earned income” qualification for Homestead Credit (from above)?                                

      • As long as the claimant has a positive amount of earned income, they meet this qualification for the homestead credit.”
        (WDOR response to us Nov 29, 2017)
      • Apparently, someone who otherwise qualified but only worked one day during the year would qualify!.  Or, worked one hour!
        In fact, someone could claim to have earned just $10 of self-employment income and would still qualify.
