On the inside of your trachea there is a mucous membrane that lines it that is sensitive and will stimulate the coughing reflex to get rid of any foreign bodies that have entered your trachea. It is part of your respiratory system.
The Best Time to File. Unlike with a paper return, there really is no best time to file a federal tax return electronically. Whether you file on Feb. 1 or on April 15, you can expect the IRS to issue a direct deposit refund within 21 days from the date the IRS accepts your return.
Filing a return through the mail is, of course, the slower of the two processes. For those who mail their federal return, the IRS will remit a tax refund within six weeks after they have been received the completed return. If you file electronically, you should receive your tax refund within three weeks.
