GoSystem Tax RS creates an electronic postmark bearing the date and time (Central time zone) when the electronic file is received at our host computers. If timeliness of filing is in question, the IRS will use the electronic postmark adjusted to the local time of the taxpayer. For example, if the taxpayer is located in the Eastern time zone, the IRS adds one hour to the electronic postmark to determine the filing time. Conversely, if the taxpayer is located in the Pacific time zone, the IRS subtracts two hours from the electronic postmark.
