We recommend that everyone who is required to file a tax return but is unable to file it on time, files for an extension by April 15th. This is our advise wither you owe money for your estimated tax liability or not. However, generally speaking penalties for not filing/paying are levied on those who owe taxes not those who owe nothing.
Now, if you or a dependent is not required to file a return because their taxable income falls below the threshold required for them to file a return, then there is no need to file for a tax extension. For everyone else who is required to file it is good practice to file an extension even if your estimated outstanding balance is zero.
For those who do not owe and would like to file an extension without paying can do so with our free print and mail option.
