Sales Tax Payment

Hello Everyone,

Please I am testing the Sales tax payment, but I still don't understand the concept. For instance, the one I used, I saw a balance in the sales tax amount, what does that balance imply? I was trying to ascertain how d system got the numbers it reversed. For the sales tax payable, if I add the posted sales tax with the balance, it sums up to what the system posted and for the receivable the total was zero which is what I expected.

I just need to understand the concept. Please can someone explain.

Thanks!
