What is a subtraction modification code?

[katie_hain]

On the NY state tax return under Other addition/subtractions Stmt (225): I get the message Sch B Pa rt 2 code is not a valid subtraction code. What does this mean? I can't seem to edit the filed that's at 0.

On the NY tax return, Form IT-225 is used for reporting modifications to income and expense items - these are adjustments you'd need to make to your federal income for New York state tax purposes.

Schedule B, Part 2 specifically refers to subtractions that flow through to you from partnerships, S corporations, or estates and trusts. These modifications should be reported to you in the statements to your Schedule K-1. 

For more information about what the different codes mean, see the NY Subtraction Modifications Chart.
