After you file

Not sure what you mean but if you do NOT have a copy of the W-2 in hand yet do NOT NOT NOT file any return as the info from your pay stub and  W-2 usually will not match  AND  the IRS has not posted when they will start accepting efiled returns  AND   until your employer files the W-3  the IRS will not process your return ... it will be on hold until they can verify the information ... SO  filing before you get the W-2 form is not WISE at all.   Last year many early birds had their returns hung up for months due to their haste.
