If you were a New Jersey resident for only part of the year, list the month and day in the tax year your residency began and the month and day in the tax year it ended. For example, if you moved to New Jersey August 4, 2020, enter 08/04/20 to 12/31/20.
You must file a return if your income for the entire year (not just your period of New Jersey residency) was more than the filing threshold for your filing status (see page 3). Only report income you earned while a New Jersey resident.
You must prorate exemptions, deductions, credits, and the pension and other retirement income exclusions based on the number of months you were a New Jersey resident. For this calculation, 15 days or more is considered a month.
If you received income from a New Jersey source while you were a nonresident, you must also file a New Jersey nonresident return.
