State tax filing

Gotcha okay, so for example lets say I moved to NYC May 1st - 121st day of the year

121 - 366 (total days in the year it was a leap year) = 245 days living in NYC

245/366 = .67%

.67 x $2500 = 1675 

That is the number I would place in the NYC portion of the table. What is the description though? and where did the 2500 number come from?

 

Thank you for all the help!
