June Accelerated Payment Information
A business designated as a mandatory payer may be subject to a penalty if a June accelerated payment is not paid by the due date. If the payment is underpaid the business is also subjected to a penalty.
The penalty is 10 percent of the difference between the required payment and what was paid. The required payment is 90 percent of the actual June sales tax, 90 percent of May sales tax or 90 percent of the average monthly sales tax for the previous calendar year.
