I finished filing my 2008 taxes and then noticed that I made a typo and underreported my W-2 income by $5 (that's just 5, not 5K or 5M). I filed Schedule B and Schedule D along with the 1040 and there were no errors on the schedules.
I'm hoping I don't need to do anything to correct this, since this particular error is not something that affects the accounting on future returns, and my additional liability is a mere $1.40. What say you?
