N.J. Stat. § 54:36-6
Where an estate was so created that the remainders or expectant estates therein were of such nature or were so disposed or circumstanced that the taxes thereon were held to be not presently payable, or where the interests of legatees or devisees were not ascertainable at the death of the testator, grantor, donor or vendor, the State Tax Commissioner may enter into an agreement with the executors or trustees for the purpose of compounding such taxes upon such terms as may be deemed equitable and expedient.
The payment of the taxes provided for in such composition shall be conclusive in favor of the executor or trustee as against the interests of such cestuis que trustent as may possess present rights of enjoyment or fixed, absolute or indefeasible rights of future enjoyment, or of such as would possess such rights in the event of the immediate termination of particular estates.
If the executor or trustee elects to defer the adjustment of the taxes until the person or body politic or corporate beneficially interested in the property chargeable with the tax comes into actual possession or enjoyment of the property, such executor or trustee shall execute a bond to the State of New Jersey, in twice the amount of the tax imposed at the highest possible rate, with such surety or sureties as the State Tax Commissioner shall approve, conditioned to pay the tax and interest thereon at such time or period as hereinabove provided, which bond shall be filed in the office of the State Tax Commissioner. Upon the filing and approval of such bond, the State Tax Commissioner shall be authorized to issue consents permitting the transfer of any and all property disclosed in the proceeding.
