Sorry if this has been brought up before.  Although the IRS commissioner a couple of weeks ago said the deadline WOULN'T be extended, the House Ways and Means Committee is requesting that the IRS extend it.  Of course, Yellen could make the change on her own.  

A smaller extension to April 30th or May 15th would be helpful, but July 15th  would be brutal. Half the benefit of this occupation is time off when the weather's nice, in exchange for killing yourself during the winter.  

I think it's more likely than not that it WILL get extended, especially with the IRS overwhelmed and the new stimulus checks likely coming in March, but even if it DOES get extended, it likely WON'T get announced until it is too late for us to make any adjustments anyway.  🙄
