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.
Now, you want to know when to expect your refund. Generally, if you e-file and use direct deposit, the IRS estimates that you should receive your federal refund between 8 and 14 days after they accept your return (i.e. the IRS does not send you a notification requesting additional information or an audit notice).
