If you have everything to file your taxes then it’s best to get it done as soon as possible. If an identity thief beats you to it and uses your social security number, or a social security number that is on your return, to file then your return will reject and you will need to file on paper to get everything straightened out. This happens more and more these days. Stores, employers, banks, etc have all had info stolen from them and this may allow others to file as you. Just this month a local employer had numerous employees info used to file returns causing this problem for them.
