Form M-5008-R — New Jersey Appointment of Taxpayer Representative

What is Form M-5008-R?

Form M-5008-R, Appointment of Taxpayer Representative, designates one or two representatives and gives them authority to obligate, bind and appear for you before the New Jersey Division of Taxation. Unless you limit it, the representatives can receive and inspect your confidential tax records and do anything you could do for the tax matters you list, such as consenting to extend the time to assess tax or agreeing to a tax adjustment. They can't endorse a refund check, and they can't sign returns or delegate authority unless the form specifically authorizes it.

The form covers individuals, corporations, sole proprietorships, LLCs, estates, partnerships, trusts and combined groups. Filing it automatically revokes earlier appointments and powers of attorney for the same tax matters and periods unless you check the box to keep them. The current edition is M-5008-R (6/26), with the instructions on pages 3 and 4.

FileIt guides you through all eight sections and prints your answers into the Division's own PDF. It pre-fills the taxpayer's name and email from the People records in your vault, shows only the parts that apply to your taxpayer type, keeps the finished PDF in your vault and can send it for e-signature by the taxpayer and each representative. You then give it to the Division yourself: FileIt never files anything for you.

How to fill out Form M-5008-R, step by step

1 Section 1: Taxpayer information

Tick the taxpayer type and give the taxpayer's name (the unitary group name for a combined group), ID number, spouse or civil union partner for joint representation, mailing address, email and phone. A combined group adds the managerial member's name and FEIN; an estate or trust adds the trustee's or executor's details.

2 Section 2: Representative information

Name up to two representatives. A tax practitioner enters their Preparer Tax Identification Number (PTIN) as the Representative ID; a representative without a PTIN enters their Social Security number. Each representative must sign and date Section 8, or the appointment is rejected.

3 Section 3: Tax matters

Choose all tax matters, or list specific tax types with their years and periods. A tax type with no year covers all years and periods; a year with no tax type covers all taxes for that year. If you list neither, the form applies to all taxes and all periods.

4 Section 4: Acts authorized

By default the representatives can receive and inspect confidential tax records and act fully for the matters in Section 3, except endorsing a refund check. Tick the box and explain on the lines to limit their power; you can attach more.

5 Section 5: Notices and communications

The Division sends original notices to you and a copy (other than automated computer notices) to the first representative. Tick a box to stop copies to your representatives, or to send copies to both.

6 Section 6: Earlier appointments

Filing this form revokes earlier appointments and powers of attorney for the same tax matters and periods. To keep them, tick the box and attach copies. You can't partially revoke an earlier M-5008-R: file a new one naming the representatives you keep.

7 Sections 7 and 8: Signatures

The taxpayer signs and dates Section 7 (both spouses or civil union partners for joint representation). An officer, partner, guardian, executor, administrator or trustee signing for the taxpayer certifies their authority. Each representative accepts the appointment by signing and dating Section 8. The appointment is void if not signed and dated.

Common mistakes to avoid

• Leaving a representative's Section 8 acceptance unsigned. The appointment is rejected.
• Entering a Social Security number for a tax practitioner who has a PTIN.
• Only one spouse signing when both are to be represented on a joint return (unless one authorized the other in writing, attached).
• Forgetting that the new form revokes earlier appointments for the same matters. Tick Section 6 and attach copies to keep them.
• Listing a period without a tax type when you meant one tax. It then covers all taxes for that period.

After you fill it out

The taxpayer signs Section 7 and each representative signs Section 8. Sign the printed PDF by hand, or use FileIt's optional e-signature, which places the signature and date boxes for each signer.

Then use it the way the instructions describe. In person at a Regional Information Center: bring the completed form signed by the representative and the taxpayer, plus one government-issued photo ID or two non-photo government IDs. In writing: upload or mail it to the PO Box on the notice with a copy of the notice and any supporting documents. FileIt doesn't send it.

FileIt keeps the completed PDF in your vault. File a new M-5008-R to change representatives or tax matters.
