N.J. Stat. § 32:3-12
The effectuation of its authorized purposes by the commission is and will be in all respects for the benefit of the people of the Commonwealth of Pennsylvania and the State of New Jersey, for the increase of their commerce and prosperity and for the improvement of their health and living conditions; and since the commission will be performing essential governmental functions in effectuating said purposes, the commission shall not be required to pay any taxes or assessments upon any property acquired or used by it for such purposes, and the bonds or other securities or obligations issued by the commission, their transfer and the income therefrom (including any profits made on the sale thereof) shall at all times be free from taxation within the Commonwealth of Pennsylvania and the State of New Jersey.
To the end that municipalities may not suffer undue loss of tax revenue by reason of the acquisition and ownership of property therein by the commission, the commission is hereby authorized and empowered, in its discretion, to enter into a voluntary agreement or agreements with any municipality, whereby it will undertake to pay a fair and reasonable sum or sums to compensate the said municipality for any loss of tax revenue in connection with any property acquired by the commission after one thousand nine hundred and fifty other than property acquired for bridge, tunnel or passenger transportation purposes. Any such payment or payments which the commission is hereby authorized and empowered to make may be made on an annual basis, in which case the payment or payments shall not be in excess of the amount of the taxes upon the property when last assessed prior to the time of its acquisition by the commission, or such payment or payments may be made in a lump sum or sums, or over a stated period of years, as shall be agreed upon by and between the commission and such municipality. Every municipality wherein the property shall be acquired by the commission is authorized and empowered to enter into such agreement or agreements with the commission to accept the payment or payments which the commission is herein authorized and empowered to make.
