Filter data based on prior year

Years are just numbers. I think you just need to adjust the formatting for the column to no commas and 0 decimal places.

tameismael , Not very clear, what you want to achieve here

You need this year vs last year flag

Year Type = Switch( True(),
year([Date])= year(Today()),"This Year" ,
year([Date])= year(Today())-1,"Last Year" ,
Format([Date],"YYYY")
)

if you need measures refer
