Hi, @Derolf.
Please allow me to share a little more information about printing sales tax payment check in QBO.
When recording a sales tax payment, the system doesn't generate an actual check, this is the reason why you can't print a sales tax check in QBO.
However, I want to ensure customers like you are having the best possible experience while working with QuikBooks. I'll take note with this so I'll be able to pass along this information here on my end.
To stay updated with the current/latest QuickBooks news and updates, you may check/visit our QuickBooks blog.
In addition, you may check our Help articles for your future reference about QuickBooks Online: Help articles for QBO.
I'll be around to help you have any other QuickBooks or sales tax questions, just add a post/comment below. Wishing you the best!
