I look for some big business outfits to move out of Seattle due to the tax. One large firm, I believe it was Amazon, stopped planning a new complex that was in the works for expansion.
If they can avoid the tax by just moving out of the Seattle city limits, Seattle will be sucking hind tit on their tax base and it will not be that much of a hardship for companies to move out next door to one of the suburb cities that will welcome the new tax base without a head tax.
