Repealed the estate tax, kept the inheritance tax
No Class B — it was abolished in 1963
New Jersey's classes run A, C, D, and E — there's no Class B. It existed once but was eliminated by statute decades ago, which is why beneficiary letters and forms sometimes skip straight from A to C without explanation.
A shorter deadline than most states
The return and full payment are due within 8 months of death — not the 9 months common in most other inheritance-tax states — with 10% annual interest on any balance unpaid after that.
