In her article outlining "28 past-due tax changes", which you can read in it's entirety here, the author Gale Cole of Avalara, points out that many changes take place at the beginning of the quarter and that "October 1 is no exception". According to Cole, 15 States had sales tax rate changes, 2 had fuel tax rate changes and two had October sales tax holiday's, one being my home state of Georgia. Way to go Georgia!
She also points out that in Washington, DC, there are new taxes for bottled water delivery service, bowling alley services and storage of household goods, to name a few. Not to be outdone by the taxman in DC, Los Angeles and San Francisco are tapping into Airbnb as a new source of revenue.
With legislatures doing what they do best, taxing and spending, I'll say that I can't imagine how businesses, or their advisors, can keep up with the burden that is our tax system without using some sort of sales tax automation software.
If you have to deal with this beastly burden regularly, kudos to you!
