Fact-checking Yes Wichita: Sales tax cost per household


The cost of the proposed Wichita sales tax to households is a matter of dispute. I present my figures, and suggest that “Yes Wichita” do the same.

At a forum on the proposed Wichita sales tax on September 9, 2014, Jennifer Baysinger told the audience that “the average family bringing in about $50,000 a year would pay about $240 a year tax.” She was speaking on behalf of Coalition for a Better Wichita, a group that opposes the one cent per dollar sales tax that Wichita voters will see on their November ballots.

In his rebuttal, “Yes Wichita” co-chair Jon Rolph disputed these figures, saying that Baysinger’s claim would mean that the average family spends $24,000 per year on “groceries and sweaters and socks.” He said a family would need to make $200,000 per year to spend that much on taxable items.

So who is correct? It’s relatively easy to gather figures about sales taxes and households. Here’s what I found.

According to a report from the Kansas Department of Revenue, in fiscal year 2013 the City of Wichita generated $372,843,844 in retail sales tax collections. With a population of 385,577 (2012 value), the tax collected per Wichita resident was $966.98.

Supporters of the proposed sales tax say that one-third of the sales tax collected in Wichita is paid by non-Wichitans. If true, that leaves $248,562,563 in sales tax paid by 385,577 Wichita residents, or $645 per person. This figure is from sales tax being collected at a rate of 7.15 percent, which implies that one cent per dollar of sales tax generates $90 per person. (This assumes that people do not change their purchases because of higher or lower sales taxes, which does not reflect actual behavior. But this is an estimate.)

According to the U.S. Census Bureau, there are 2.49 persons per household in Wichita. That means that a one cent per dollar sales tax has a cost of $224 per household. That’s close to Baysinger’s figure of $240.

We could also take sales tax collections of $248,562,563 and divide by the 151,309 households in Wichita to get a figure of $1,642.75 in sales tax paid per household. Again, since that is tax paid at the rate of 7.15 percent, it implies that one cent per dollar of sales tax generates $230 per household, subject to the same caveats as above. Again, this is close to Baysinger’s figure.

These results are close to my estimation of the cost of the proposed sales tax derived in an entirely different way. I took Census Bureau figures for the amount spent in various categories by families of different income levels. For each category of spending, I judged whether it was subject to sales tax in Kansas. The result was that the average household spent $22,287 per year on taxable items. One percent of that is $223, which is an estimate of the cost of a one cent per dollar sales tax per household. For households in the middle quintile of income, the value was $194. See Wichita sales tax hike would hit low income families hardest for details and charts.

How can the claims of Baysinger and Rolph be so far apart? I’ve presented my reasoning and calculations. The results are figures very close to what Coalition for a Better Wichita is using. Wichita voters might ask that Jon Rolph or one of the other co-chairs of “Yes Wichita” do the same.
