New Jersey Inheritance Tax Return (Form IT-R): A Guide for Executors

Who has to file an IT-R

Work through the Division's flowchart for deaths on or after January 1, 2018. Count every person or organization that receives anything, by any route: the will or intestacy, a surviving joint owner, a POD or TOD beneficiary, the named beneficiary of an IRA, annuity or pension, and anyone who received a gift of $500 or more in the 3 years before death.

1. Did the person live in New Jersey? If not, this is the wrong return: nonresident estates use Form IT-NR or L-9NR, and only for New Jersey real estate.
2. Does anything pass by a disclaimer? If yes, file an IT-R.
3. Is everyone Class A? Class A is a spouse, civil union or registered domestic partner, children (adopted and stepchildren too), grandchildren and their descendants, parents and grandparents. If even one beneficiary is not, file an IT-R.
4. Does anything pass into or through a trust? If every trust beneficiary is Class A, Form L-4 may get the waivers, though the Division can still ask for a return. Otherwise, file an IT-R.
5. Everyone Class A, no disclaimer, no trust: no return. Use Form L-8 for the bank accounts and Form L-9 for the house.

A return can be required when no tax is due. A $10,000 bequest to a church or an animal shelter (Class E) is untaxed, and so is $20,000 to a sister (Class C, under the $25,000 exemption), but either one means the estate files an IT-R so the Division can issue the waivers.

Due date, extensions and interest

The return and the tax are due 8 months after the date of death. Move forward 8 calendar months and keep the day: a death on June 16, 2026 is due February 16, 2027. If that month has no such day, the due date is the first of the next month: a death on January 31, 2026 is due October 1, 2026, and one on June 30, 2026 is due March 1, 2027.

• Form IT-EXT extends the time to file, never the time to pay.
• Form IT-EP sends an estimated payment before the return is ready. Pay a good estimate by the due date; an overpayment is refunded after the assessment.
• Interest is 10% a year on Class C and D tax still unpaid after the due date, counted in days: tax × 10% ÷ 365 × days late. On a $26,305 tax that is $7.207 a day, about $219 a month. Paid 44 days late, the interest is $317.11.
• A bank must honor a check written on the person's frozen account to pay the inheritance tax, if the money is there, so a frozen account is no reason to pay late.

The New Jersey inheritance tax calculator gives each heir's tax and the due date for a date of death.

The return, part by part

The current return is the 12-24 revision. Send every schedule, with $0 on the total line of any that does not apply; a return with schedules missing is held. Value everything at the date of death, not the date you file.

Three rules that trip people up

• Joint accounts are reported at full value unless the surviving owner proves what they contributed, with an affidavit and records.
• A brokerage account is one line on Schedule B-1 at its total value. Splitting its stocks onto B-2 and B-3 produces a waiver that does not match the account.
• Life insurance paid to a named beneficiary is not reported. Insurance paid to the estate is, on Schedule C.

How each beneficiary's tax is worked out

Add up everything one person receives from every schedule, then apply their class's rates to that total alone. Never combine two beneficiaries before applying the rates, and the $25,000 exemption is for Class C only.

• Class C (brothers and sisters, a child's spouse or civil union partner): first $25,000 exempt, then 11% to $1,100,000, 13% to $1,400,000, 14% to $1,700,000 and 16% above.
• Class D (everyone else): 15% on the first $700,000 and 16% above, from the first dollar. Under $500 to one person is untaxed; at $500 the whole amount is taxed.
• Classes A and E owe nothing, but still appear on Schedule E and the Summary Page.

A sample estate with a $883,324 net estate, from the workbook below:

Two-thirds of that tax ($17,400) is on the CD and the IRA, which never passed through the will, and the $15,000 gift to the friend added $2,250 to hers. The sister's tax is ($63,000 − $25,000) × 11% = $4,180.

Deductions on Schedule D

Deductions lower the net estate, and so the residue. They save tax only when the residue goes to Class C or D beneficiaries: each $10,000 deducted saves $1,500 when the residue goes to nieces and nephews, and nothing when it goes to children.

• Allowed: funeral costs; Surrogate fees and other administration costs; reasonable fees of a New Jersey attorney, CPA or enrolled agent for the return; the executor's commission up to the legal maximum; mortgages and home equity lines on property reported on Schedule A, at the lender's date-of-death balance; debts owed at death, such as final bills, medical bills not covered by insurance and property tax already due.
• Not allowed: property taxes, utilities, condo fees and upkeep after the death; fees for the estate's Form 1041; the inheritance tax itself; a mortgage on property that is not reported, such as a house held with a spouse as tenants by the entirety or one in another state.

Signing, paying and mailing

• Signature: the executor, administrator or heir-at-law signs the Cover Page in front of a notary. The Division needs the original; it does not process a return until a valid one arrives.
• Attachments: the death certificate; the Letters Testamentary or of Administration; the complete will with every codicil; any trust agreement; the person's last federal Form 1040; any disclaimers; and the support each schedule asks for, such as the deed, the date-of-death statements and the funeral bill.
• Payment: a check for line 21 with Form IT-PMT, payable to "NJ Inheritance Tax" as the instructions say, with the person's name and Social Security number on it.
• Mail: by USPS to NJ Division of Taxation, Transfer Inheritance Tax, PO Box 249, Trenton, NJ 08695-0249. By UPS, FedEx or another private carrier, to the same name and PO Box at 3 John Fitch Way, 6th Floor, Trenton, NJ 08611. Use a trackable method and keep a full copy.

After you file: waivers

The IT-R is how you ask for waivers. After it reviews the return and the tax is paid, the Division issues a Form 0-1 waiver for each New Jersey asset: the house, and each bank and brokerage account, listed exactly as you registered it on the schedules. Plan on several months; about 40 to 50% of returns are audited. Until the waivers arrive, a bank may release up to 50% of an account to the executor, and the title company needs the real estate waiver before a sale can close. The New Jersey waiver guide covers the L-8, L-9 and 0-1 in detail.

Common mistakes

• Using an L-8 or L-9 when a sibling, niece, nephew, friend or charity receives anything, even as a POD or IRA beneficiary.
• Leaving out joint accounts, POD and TOD accounts, IRAs, annuities or gifts in the last 3 years.
• Combining beneficiaries before applying the rates, or giving a Class D beneficiary the $25,000 exemption.
• Waiting for the return to pay. Send an estimated payment by the 8-month date.
• Valuing the house from an online estimate or the tax assessment instead of an appraisal, a sale or a market analysis.
• A Cover Page signed by the wrong person, not notarized, or photocopied.
