Several communities in Silicon Valley are considering levying special taxes on large companies, possibly affecting some of the biggest tech companies:

Cupertino, Mountain View and East Palo Alto have begun to ponder new taxes based on employer headcounts — levies that could jolt Apple and Google — and if voters endorse the plans, a fresh wave of such measures may roll toward other corporate coffers.

Alarmed by traffic and other issues brought on by massive expansion projects, the three Silicon Valley cities are pushing forward with separate plans to impose new taxes that could be used to make transit and other improvements…

A lot of factors point to this being a prime time for efforts such as these. San Francisco ranked fifth worst for traffic congestion in the world — and third worst in the U.S. — last year, according to INRIX Global Congestion Ranking. Record housing prices in 2018 boosted the median price of a single family home in the Bay Area to a record $893,000 in April, according to a CoreLogic report.

Federal tax cuts also have improved the balance sheets on an array of U.S. companies, large and small. Silicon Valley’s largest tech companies have contributed to the gridlock on freeways and soaring housing costs as they’ve grown rapidly in recent years, with brisk hiring and expansion in unexpected areas and mega-leases that gobble up huge swaths of office space.

If this works the way that some would argue it does, then the local taxes will be viewed by the tech companies as an unnecessary burden for their operations. They should then consider moving elsewhere where they are not subject to such local taxes. Indeed, if they wanted to move sizable operations, they could probably get numerous communities to offer them tax breaks.

However, this assumes that the local taxes are the primary factor that determines where companies and organizations locate. Instead, there are a variety of factors that both support and work against staying in their current location. I assume these are important reasons for why Apple, Facebook, Google, and others are in this location: the construction and maintenance of large headquarters, proximity to other like-minded organizations, an talented employee pool nearby, and the proximity to major cities like San Jose and San Francisco. Are local tax issues more important than these other concerns? Probably not. And even if they are, it would take some time before a large organization could significantly alter their operations in response.
