If you do not file your tax return by the due date (usually April 15), you will incur an IRS civil penalty (the failure-to-file penalty) of 5 percent for each month or part of a month that your return is late.
I have to say that I have kept chicken in the fridge for longer than 2 days and not died. Some even have best before dates 3-4 days in. The quality definitely suffers, and I'm sure there's some risk, but it's probably low.
How long will a roast chicken keep in the fridge? When I roast a chicken, we never finish it right away. How many days can I continue to safely use the leftovers?
