I had to amend my federal return. the change did not change my NY tax liability. must I still file an amended ny nonresident return

No, if the state tax did not change, you do NOT need to amend the New York

You must file an amended New York State tax return if:

• you made an error when you filed your original New York State income tax return;
• the Internal Revenue Service (IRS) made changes to your federal return;
• you need to file a protective claim; or
• you need to report a net operating loss (NOL) carryback.
