Grand Forks released retail sales tax collections which are for the month of December 2017. There are various different ways to look at the number. It is a .31% increase over December of 2016. An increase is an increase I suppose, though it should be cause for concern if the general optimism permeating the economy surrounding the tax cut happened to miss Grand Forks. The January and February releases for this year, which represent sales tax collected in November and December of 2017, are around 6.5% less than this time last year. It is also the case that 17 of the last 38 months have been lower than year ago values for sales tax collections.
