NYC Part Year Return not Calculating Correctly

I moved from NYC to Mass and am having problems with the NYC part year return.

NYS Form IT-360.1, Change of City Resident Status, Part 1 Colum B - Amount of New York City resident period correctly picks up all the allocated New York items in Column B, but when it hits line 19 New York Modifications (for exempt allocated retirement income and interest from US govt securities), instead of subtracting the amount, it adds it to the New York Adjusted Gross Income. This seems incorrect in that it's adding the allocated exempt NYC income back into the NYC tax calculation. It's increasing my NYC tax considerably.

I've looked at all the entries I've put into the NYC portion and they seem correct. The New York state allocation and tax on IT-203 are all calculating correctly.

What should I do to correct this?

First, how many days were you a New York resident? If you were there for more than half of the year then New York considers you a resident for income tax purposes.

Additionally, for those who are part year residents, New York uses all of your income to figure out what your tax rate would have been if you were a resident, and then charges you that tax rate on the income that you do have taxed by them. Not the nicest way to handle taxes but that is how they do it.
