Costco sales tax split deal almost over

Manteca is making the final $50,000 sales tax split payment this summer to Costco.

And to mark the occasion city leaders are hoping to have corporate representatives from Issaquah, Wash., attend a presentation in Manteca to celebrate the completion of the deal that brought Costco to Manteca in 2008 while bringing consumer dollars that city residents had been spending at Costco stores in Tracy and Modesto back into Manteca along with local sales tax.

The last payment means the general fund sales tax will swell by at least $400,000 a year due to the end of the sales tax split.

Manteca leaders in 2006 were worried about “retail bleed” that was seeing large amounts of local residents’ consumer dollars and the sales tax they paid going to surrounding cities. Thanks to proprietary sales tax information the city received as the sales tax split deal was being formulated, the city discovered every year Manteca residents shopping at the Modesto and Tracy Costcos they were dropping $600,000 in local sales tax.

Manteca municipal officials found out through commercial leasing agents with Kitchell that Costco was going to locate another store in the region and were considering the east side of Modesto.

Costco is a huge generator of taxable sales in the communities they are located in.

Manteca municipal leaders figured if that happened it would have been years before Manteca had a chance at landing a Costco. And down the road that may not have happened as Lathrop would have been grown making the appeal of locating on the Interstate 5 corridor as being a central location for the Manteca-Lathrop-Weston Ranch region would have been a tough one for Costco to pass up.


Costco told city leaders the Manteca market numbers “weren’t high enough” yet to locate a Costco in Manteca. They’d consider Manteca, though, it there was some type of “help” in covering the site development.

When Manteca approached Costco the firm originally wanted a straight sales tax split with no cap but Manteca balked.

In a 2012 interview then City Manager Karen McLaughlin said, “We basically said ‘what is the amount you need to make the deal work’.” 

Costco decided on $3.7 million — the cost of building a store in Manteca.

Even after they were told $3.7 million, the City Council wasn’t convinced it was a good deal.

The City Council retained a Los Angeles firm that specialized in such analysis that also – through Costco’s permission – got access to confidential and proprietary information that is collected by the State Board of Equalization on each business that has taxable sales in California.

They used that hard, state-audited data to determine whether a sales tax split deal would really benefit Manteca.

Data recorded every time a club member used their Costco card showed Manteca residents spent $6 million in taxable sales at Costco stores in Modesto and Tracy in 2006.

The $6 million Costco was pulling out of Manteca consumer pockets represented $600,000 in local sales tax that Manteca residents were paying to support municipal services in Modesto and Tracy.

The end result of the discussions with the big box retailer was that it would take $3.7 million for Costco to build a wholesale store in Manteca. The $3.7 million would come out of sales tax the city would receive from Costco shoppers buying items at the store. The deal gives Costco 45 percent of the city’s share of sales tax — excluding Measure M public safety sales tax that the city would retain — in any given year until the $3.7 million obligation was met.

Costco meet several critical criteria to get the council’s nod for the deal. First, Costco could prove they were already taking a significant chunk of consumer dollars out of Manteca. Second, there wouldn’t be a major shift of taxable sales dollars on non-grocery items from existing Manteca stores.

Based on recent annual payments to Costco, they are collecting more than $810,000 in local sales tax from the Manteca store on taxable sales of $81 million. Non-prepared food items are not taxable.
