I have just filed the tax return. However, I didn't receive any tax forms from my bank and so the tax refund doesnot include any interest earned via bank. I don't know why my bank didn't send me any such forms.. Maybe its because that I have just opened my savings account (late 2008) and that the interest is less than a $. I am curious to know if IRS will get back to me as trying to hide some income and penalize me.
