OK I thought it was all working, at least the SQL work and I have the local sales tax module in the total and under the tax rates.

I added one city (Lynnwood) with a tax rate of 9.5% (I also just tried the zip code) but nothing shows up on the check out page and it is NOT added to the total.

Any thoughts? I tried from scratch 2.2, added 2.3 and still nothing add to the cart.

Here is the debug results:
