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.
The 5 week period is usually about right for something like a federal return. A state return, on the other hand, will take about 6 to 8 weeks. The process takes a little longer when this is done by mail. A 4 week return for electronic filing may actually take closer to 6 weeks with a postal check.
