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.
However, it may take 8 to 12 weeks or longer to process the return. If 8 weeks have elapsed and you have not received your refund, call (800) 829-1040. That takes care of your federal tax refund. Almost all states that have an income tax also have a web-based form for checking the refund status.
