QB Issue Resolution:
I can help walk you through getting back to the old Sales Tax version in QuickBooks Online (QBO).
Just to confirm, are you referring to the Automated Sales Tax feature as the new version? If so, please note that once you go back to the old version, you can no longer re-enable this feature.
1. Go to the Taxes menu at the left pane, then Sales tax.
2. Select Sales tax settings in the upper right.
3. At the bottom, you’ll see “Want to temporarily switch to the old tax center? Switch here.” Click the here link.
That should do it. For more information, you can also check out this article for future reference: Set up and use Automated Sales Tax.
