@erin814 I decided to go back to using a sales tax table provided by the state I operate in, since I only have the one physical presence. WooCommerce recommends TaxJar, if you don’t want to use their plugin which uses Jetpack services, but I haven’t found TaxJar to be the most accurate solution from past experiences.

It’s notable that the Supreme Court decided in June that each state can now require sales tax to be collected on internet sales. It’s going to be a mess while states figure out the best way to (ab)use this power, and I think most tax solutions will see an overhaul once laws are actually passed in each state. I’ll probably retest my options at that point.
