Where is your official residence? Which state issues your driver's license? Where do you vote? Students are not always residents of the state where they attend school.
Q1) Will Income A will be allocated to NYC, subject NY state and NYC city tax? OR will it be subject to PA and Philadelphia city tax.
Just to clarify, you worked remotely from Philadelphia for a job that was based in NYC?
When you filled out your W-4 what state was your address? When you looked at your pay stubs what state withheld taxes?
It looks like New York taxes remote workers using the "convenience rule". See
here.
Q2) Will Income B(CG), and C(CGD) be subject solely to PA state tax?
If you never resided in NY you should not have to pay NY state taxes on B and C. But
if NY taxes remote workers like you, B and C may affect your NY tax bracket. See the answer to Q4.
Q3) Will B, and C be subject to Philadelphia city tax?
If you were were living in Philadelphia all year, then probably yes. You'll need to read up on the state and local tax rules.
Q4) Will income D be allocated to PA/Philly and subject solely to PA and Philly tax?
It depends on how non-resident out-of-state income is taxed in NY. Some states ignore non-resident out-of-state income completely and other states include it in such a way that the state tax bracket is higher. The out-of-state income is not taxed specifically, but with the bracket being higher it increases the taxes to a degree.
Q5) What is the income threshold above which CG tax rates would change?
See the table
here. These only apply to long-term gains/distributions.
You need to download the New York and Pennsylvania state tax forms and instructions.
