Hi, I am filling NY Annualized Income form. NY income is federal adjusted gross income reduced by 529 plan contribution. How should I account for 529 contribution deduction when doing quarterly breakdown of income flow? Divide it by 4 equal parts and subtract from each quarter' use as percentage of total or apply at a last or quarter when 529 contribution was made?
and the following question, what rules apply to deductions in next forms, e.g. use in a last quarter, divide equally or apply proportionally to income?
