Calculated Column Based on Unrelated, Filtered Table

Currently, I have 2 tables : SalesTable and FilterTable. SalesTable is my main data table with 20+ fields, which includes columns called "Price with Tax" and "Price without Tax". FilterTable only contains one column and has 2 rows: "Price with Tax" and "Price without Tax". My goal is to have a filter with the values from FilterTable, and when the user selects one of the values, I'll have a created DAX column called "Final Price" to take that filter value and update the DAX calculation accordingly. Right now, I have the filter set up and the DAX forumula below to create my new FinalPrice column - when the user changes the filter value, this calculation changes as well.

This is working perfectly, however, it's set up as a measure and not a standard column (and I need this to be evaluated at the row level). When I try to convert this to a column, the dynamic filtering does not work. I select different filters but the calculation does not change. Is there an easy way to update the below code to get this workable for a column? I've tried removing the MAX() pieces and tweaking some other parts, but no luck.

FinalPrice = 
IF (AND(HASONEVALUE(FilterTable[FilterColumn]),MAX(FilterTable[FilterColumn]) = "Price with Tax"),
    MAX(SalesTable[Price with Tax]),

IF(AND(HASONEVALUE (FilterTable[FilterColumn]),MAX(FilterTable[FilterColumn]) = "Price without Tax"),MAX(SalesTable[Price without Tax]), 

IF (
        NOT (ISFILTERED ( FilterTable[FilterColumn]) ) ),
        BLANK ()
    )
))
