For example, the electric company may add an additional $63.82 for the effect of the 6% utility tax on an electricity bill for $1,000. Any such amounts that are charged by the business to the consumer must be included in the measure of tax.       

When are the utility tax returns due?

Utility tax returns are generally due on a monthly basis on or before the last day of the following month in which the tax is accrued. For example, the June return is due by July 31st.

Taxpayers who are expected to owe less than $1,000 per month may submit returns on a quarterly basis, which are due on or before the last day of the month following the end of the calendar quarter.
