Opened up, question by question

Does my LLC from another state have to register?

The order matters: the New Jersey Division of Revenue and Enterprise Services (DORES), Department of the Treasury gets the registration first, and the LLC starts doing business in New Jersey afterward.

njportal.com holds the original, confirmed October 2026

How much does registration cost?

The state charges $100, and a service adds $199.

Over three years the state's fees reach $250, counting any recurring report. nj.gov holds the original, confirmed October 2026

Which form is inside the filing, and where does it go?

You open one form, the Application for certificate of authority (Public Records Filing, entity type FLC), and send it to the New Jersey Division of Revenue and Enterprise Services (DORES), Department of the Treasury.

Attach good standing certificate.

What is due after the LLC registers?

A recurring annual report follows, priced at $75.

In the state's words, the date is your anniversary month.

Why is the stack in this order?

On what is inside the price (29%), Mainstay Filing comes out ahead.

63% of the score comes from total across three years and what is inside the price.

An LLC registering out of state already works in two states, and the first pick can serve both.

Also worth asking

Do I still need an agent in my home state?

Yes. Think of two separate rule books, your home state's and this one's. Mainstay Filing works in both, so a single account can serve the pair.

What do the picks cost over three years?

Opened up over three years: Mainstay Filing at $497, New Jersey Registered Agent.co at $397, Registered Agent NJ.org at $397, services only.

What do these numbers rest on?

Two kinds of source feed this page: New Jersey's official documents for what the state charges, and company price pages for what services charge.

Does the law require one?

No law requires a service. It is a paid convenience.

Will a service file the registration for me?

Handled: submitting the registration is part of every pick's service, and the state's fee stays level.

What is the best foreign registration service for New Jersey?

Mainstay Filing, because registering costs $199, and the registered agent comes free until year two. Then New Jersey Registered Agent.co and Registered Agent NJ.org.
