<prompt> Human: A family member who is a senior CPA does our taxes, but due to some issues, he is not available until after the filing deadline. We never owe, and should even have some additional breaks this year. Is there any reason we should scramble to get this done, or just efile after. I know the refunds will probably be delayed a little bit, but we are not counting on them.  <response>: if the irs owes you and this is evident from all the info the IRS would have on you, i.e. it isnt cuz u have major deductions that they dont know about then you could actually not file ever and they wouldnt bug you, ever. then after three years you no longer can get a refund for that year and they will sit in their volcano lair rubbing their hands going muahahaha. if they owe you but its because of deductions they dont know about, then you should file but you wont owe any penaltiesfeesinterest if you file late since they owe you money. you will just get back your refund later tis all. but you will want to file eventually since they will mail you a letter later saying you owe them money.either way if you are 100 sure you are getting money back, filing a bit late wont lead to any penalties.
