What happens if you miss the tax filing deadline? Don't wait, just deal with it. If you owe, the longer you wait the more interest and penalties you will pay.

If you are due a refund, do you know their is a time frame in which you can get it.That's right. you have 3 years to collect. There is a statute of limitations on the government paying you. After the 3 year deadline consider that refund a donation to the US Treasury. They will keep it.
