E-filing refers to the electronic submission of documents, typically tax returns, to government agencies. This process allows individuals and businesses to file their taxes online, making it faster and more efficient than traditional paper filing. E-filing systems often provide instant confirmation of receipt, reducing the anxiety of whether documents were submitted successfully. Many countries, including the United States, encourage e-filing due to its convenience and accuracy. Software programs and online platforms help users prepare their returns, often including features like error-checking and automatic calculations. Additionally, e-filing can expedite refunds, as electronic submissions are processed more quickly than paper forms.
