Which of the following is an advantage of e-filing?

Faster processing times is a significant advantage of e-filing because electronic submissions can be processed more quickly than traditional paper filings. When documents are submitted electronically, they are often immediately received and can be routed directly to the appropriate department for review and action. This reduces delays associated with physical mail, such as time spent in transit or potential loss of documents. Moreover, e-filing systems are often designed to streamline the review process, allowing for faster approvals and responses.

In contrast, increased paper usage and mailing costs would not be considered advantages of e-filing, as the method typically aims to reduce both. Longer submission times directly contradict the efficiency that e-filing aims to provide, which focuses on promptness and getting matters resolved quickly.
