I can't access your tax information, so I can't analyze why this year is different from last year.
I can explain the basic requirements for the rate reduction credit.
- If you income is more than $500,000, you are not eligible.
- You must file as Single, Head of Household or Married filing jointly.
- You must be a resident or part year resident of NYC.
If you think you were eligible for the rate reduction last year as well, you can amend your 2018 tax return.
