<p>IDOC postmark deadline is March 1st. But my parents won't be able to complete their 2006 income tax return before then. I only have copies of their W-2 forms, but no 1040A nor 1099. Our income 2005 on the 1040A form was 14000 approximatedly. However, it is very hard to estimate the 2006 one with accuracy because my father just changed job last year. </p>
<p>What happens if the IDOC don't get to be sent on time?</p>
