Historically sales tax tends to grow (not every year) so local governments like having it as a revenue source and in Jefferson and St. Lawrence Counties the initial political support for imposing a local sales tax came from towns and villages who were cut in on deal.
Only counties and cities have a statutory claim to sales tax, so any deal to carve it up have to be between a county and city.
So in SLC, if the county wants more, the City of Ogdensburg should insist its 6.4% remain the same and any reallocation come from the town and village portion.
Last year when Jefferson raised it's tax by a quarter point, they didn't broach the distribution so all the other entities got the benefit of a tax hike without voting for it.
