3-year filing deadline: April 17, 2021 or May 15, 2021?
I'm an individual filing a late federal income tax return (realize I'm late but I'm trying to get caught up) and have an applied balance (credit). I searched and this same question was asked a few weeks ago but I just want a confirmation of the 3-year windows filing date because I don't want to lose my applied balance if I don't file within the 3 year window. Also because it's typical in business (like financial institutions regarding stale checks as an example) for a date-to-date window to apply (ie April 17, 2018 due date + 3 years would be April 17, 2021), but the prior response I read indicated that because the 2021 filing deadline is now May 15, 2021 (or June 15, 2021 for those in Texas and Louisiana) I could wait until May 15, 2021 (or June 15, 2021 for the two later states) to file a federal income tax return due 3 years ago. Again, I don't owe any tax payment but instead i have a credit just trying not to violate any IRS guidelines. I also tried searching the IRS site and it only mentions the 3-year window but doesn't mention (or at least I couldn't find it) what happens in a delayed filing deadline year. Other people I know who are also filing late have asked me the same question about the filing date. Any clarification or verification is greatly appreciated by myself and late filers.
