Negative Sales Tax Payable on a cash basis Balance Sheet

A negative balance usually means QuickBooks shows that the tax agency owes you money.

Why this happens
If there is a mismatch due to pay sales tax on an accrual basis but you run reports on a cash basis, this mismatch can cause negative balances. This discrepancy often appears when reviewing sales tax reports in QuickBooks Desktop. 

Quick tip

• Select Sales Tax, then open Company Preferences.
