Regarding mandatory e-filing for 1040ES as well as Annual Sales tax filing

 

“Recognizing the potential inconvenience for taxpayers at this time and limited benefit to the state, DRS has determined that (1) individuals will NOT be required to make estimated income tax payments electronically and (2) annual sales tax filers will NOT be required to file or make payments electronically. Taxpayers are still urged to take advantage of the ease, speed and certainty of filing and paying taxes through the DRS on-line Taxpayer Service Center (TSC) or by phone through Telefile.”
