What is at question is how the individual states handle their 'SaLT' (State and Local Taxes) returns for this UI payment. They CANNOT disallow this Federal Tax reduction BUT they CAN refuse to follow suit in making the same concession for their returns. There is nothing requiring them to follow this US Congress mandate, this is Federalism at work!

Another error as this 'fix' is not limited to this 'filing season' but to tax returns reporting UI (Unemployment Income) received in Calendar Year 2020 and AGI less than the cut-off limits. Thus a tax return filed with an extension on October 10th of 2021, for tax year 2020, will get the same treatment as one filed on or before 17 May 2021!
Ok so why hasn’t big mouth Schumer done this for NY.
