Adjust tax due (or credit) from previous periods?

Hi there, 

The Sales Tax module in QBO is a great way to track and calculate your sales tax in a hassle-free way. The great thing about QuickBooks Online is that there's tons of flexibility for things like adjustments. I know how important it is for any small business owner to have control over their bookkeeping, so I'd be happy to shed some light on this for you.

Take a look at this helpful article to see how to make adjustments: Adjust sales tax. The adjustments will take place during the filing process, which you can review here: File sales tax. 

This should help get you back on track. If you run into any other questions, please don't hesitate to reach out to our tech support team.

Have a great day.
