Withheld taxes are payable quarterly, monthly, or semiweekly, as specified in this section. If the Secretary finds that collection of the amount of taxes this Article requires an employer to withhold is in jeopardy, the Secretary may require the employer to file a return or pay withheld taxes at a time other than that specified in this section.
An extension of time granted to file a return for federal employment taxes attributable to wages is an automatic extension of time for filing a return for State income taxes withheld from the same wages, and an extension of time granted to pay federal employment taxes attributable to wages is an automatic extension of time for paying State income taxes withheld from the same wages. An employer who pays withheld State income taxes under this subsection is not subject to interest on or penalties for a shortfall in the amount due if the employer would not be subject to a failure-to-deposit penalty had the shortfall occurred in a deposit of federal employment taxes attributable to the same wages and the employer pays the shortfall by the date the employer would have to deposit a shortfall in the federal employment taxes.
