A recent analysis by researchers at the University of Wisconsin-Madison revealed that employers contributed significantly higher amounts of capital to defined-benefit pension plans in 2017, likely because of the new tax law signed by President Donald Trump. That law cut tax corporate tax rates from 35 to 21 percent starting this year and provided an incentive for corporations to increase deductions in 2017, including deductions for pension contributions.
The study analyzed data samples taken from over 400 non-financial firm which calculate their financial statements on a calendar-year basis and found that, on average, that firms increased their unexpected pension contributions by $16 million each. These unexpected pension contributions are considered the difference between the amount a firm contributed and the amount of money it was expected to contribute on prior-year financial statements.
Those numbers came out to a 24-percent increase in 2017 on average compared to the same averages for individual firms from 2014 to 2016. Furthermore, the study determined that taxpaying firms made larger unexpected contributions than non-taxpaying firms which the researchers took as a sign that the increased contributions could be due to the cut in corporate tax rates.
