P.L. 2023, c.125 establishes a Gross Income Tax credit for Ó£»¨ÊÓÆµ residents who successfully win their own legal challenge to the taxing of their income by another state when the income is earned while they are located physically in Ó£»¨ÊÓÆµ. 
The credit provided under the new legislation applies to Tax Years 2020-2023.
In order to qualify for the credit, the taxpayer must:
The final judgment in the taxpayer’s favor from the other state’s tax court or tribunal must also satisfy the other state’s laws for establishing finality. This includes a New York State Order of Discontinuance issued by their Division of Tax Appeals and a corresponding Joint Stipulation of Discontinuance to verify that a final judgment was obtained by the taxpayer.
The refund from the other state requires an adjustment to Ó£»¨ÊÓÆµâ€™s credit for taxes paid to another state and will likely result in additional tax due to Ó£»¨ÊÓÆµ. However, the credit provided under the new legislation allows a credit of 50% of the additional tax that is owed to Ó£»¨ÊÓÆµ. This credit is refundable, meaning the resident can receive the full value, even if the credit reduces Ó£»¨ÊÓÆµ taxes to below zero.
To receive the credit, the taxpayer must submit a copy of the final judgment from the other state’s tax court or tribunal with an amended NJ-1040 reducing the credit for taxes paid to another state. In addition, the taxpayer may include a request for a waiver/abatement of interest and penalties, which the Division will consider and grant on a case-by-case basis.
Taxpayers should submit all of the above to the Ó£»¨ÊÓÆµ Division of Taxation, Gross Income Tax Audit Branch, PO Box 288, Trenton, NJ 08695-0288, attention: Chief.
