What you probably want to know

How much should I set aside to form it?

The state fee is $50. Hire a service and add $199.

By year three the state has taken $50 in total. nmonesource.com, confirmed October 2026 (official)

What do I file and who gets it?

Your LLC exists once the New Mexico Secretary of State approves the Articles of Organization.

Cited law: NMSA 1978, § 53-19-7. nmonesource.com, confirmed October 2026 (official)

Do I have to name a registered agent?

Every LLC must name a registered agent with an in-state street address.

A New Mexico resident, or a corporation, LLC or partnership formed in New Mexico or authorized there whose place of business is the registered office.

nmonesource.com, confirmed October 2026 (official)

What comes due in later years?

No yearly report and no report fee.

Is it okay to do the filing myself?

You don't need a service. State fees alone would run $50 across three years.

Services bill $397 to $597 over three years for taking this off your hands.

What put number one on top?

Work taken off your hands, worth 31%, put Mainstay Filing first.

33% of the score is cost across three years, 31% is work taken off your hands, and three smaller checks split ties.

It still wins on what the price covers, but by a smaller margin than where a yearly report exists.
