Earlier this week, we posted that the U.S. and Canada extended their tax deadlines. As previously mentioned, moving the filing and payment deadlines out to July 15 eliminates potential complexity, and results in welcome relief for both taxpayers and tax preparers. 

But this new tax alert from GTN explains that filing and payment deadlines continue to evolve in response to COVID-19 at the state level, too. While states often try to align with federal filing and payment deadlines, each state can make their own decision, so things can vary at the state level. GTN notes that as of March 26, 27 states (including the District of Columbia) had adjusted their deadlines to match the IRS, and six other states along with Puerto Rico had extended to other dates: Iowa (July 31), Idaho (June 15), Mississippi (May 15), Oregon (April 30), Virginia (June 1), Washington (June 15) and Puerto Rico (June 15). As of March 27, the number of states that have aligned to the federal extension date (July 15) has increased to 31. 

Our friends at GTN explain that:
