Firstbase Alternative for a Foreign-Owned New Mexico LLC

Short answer: Firstbase can't form a New Mexico LLC, and its $99 price leaves out the $299-a-year registered agent every company needs. If you've chosen New Mexico, our Non-US Founder Package is $399 plus the $50 state fee with the agent's first year included. If Delaware or Wyoming would do just as well, Firstbase is worth a look, especially for its tax filing product. This is our comparison, and we sell the package on the right-hand side.

What Firstbase does well

• A priced tax product for foreign owners. Filing for a non-US single-member LLC costs $899 a year, a figure few competitors publish.
• Mercury on the Start page, where Firstbase offers access to the application.
• No SSN or ITIN required for the EIN, per Firstbase.
• LLC or C-corp in Delaware or Wyoming.
• Room to grow: Mailroom from $35 a month and an accounting product.

The math for a New Mexico LLC

Firstbase has no New Mexico option, so the nearest like-for-like is a Wyoming LLC through Firstbase.

• Firstbase (Wyoming), first year: $99 + $299 agent + $100 state fee = $498.
• Our package (New Mexico), first year: $399 + $50 = $449.
• Years two and three: $299 a year for Firstbase's agent, $99 a year for ours.
• Three-year totals: $1,096 against $647, a $449 difference.
• State upkeep: Wyoming adds its own annual report and license tax; New Mexico has no annual report.

How our package works

1. Complete the order form once.
2. Our team files your Articles online with the New Mexico Secretary of State.
3. Your certificate is issued and saved to your dashboard.
4. We send you a finished SS-4 to e-sign, prepared for a responsible party without an SSN.
5. Signing makes your bank application for our partners ready to go, with your company documents inside. It doesn't sit waiting on your EIN: once you approve, it's sent. The decision is our partners', and we can't promise an account.
6. The SS-4 is faxed to the IRS, which usually returns an EIN within two to eight weeks.

Choose Firstbase if

• You want your yearly federal filing handled for a stated $899.
• Delaware or Wyoming works for you, or you're forming a C-corp.
• You'd use a mailroom or accounting service from the same provider.

Choose our package if

• New Mexico is the state you want.
• You'd rather renew the agent at $99 than $299.
• You want your bank application drafted for you.

After formation in New Mexico

A New Mexico LLC doesn't file an annual or biennial report; it just has to keep a registered agent and office on the state's records. Federal reporting like Form 5472 and any gross receipts tax registration are yours to arrange with a tax adviser, since our package doesn't include tax work.

Common questions

Can Firstbase form my New Mexico LLC?

Not through Firstbase Start, which is available for Delaware or Wyoming. Firstbase sells registered agent service in all 50 states, but it doesn't form New Mexico companies under Start.

Firstbase is $99. Why is your package $399?

Start covers formation and the EIN but not the registered agent, which Firstbase says is required and charges $299 a year for. Our price includes the agent's first year and a prepared bank application.

What's the realistic first-year cost with each?

Through Firstbase in Wyoming: $99 plus $299 for the agent plus $100 to the state, $498. With us in New Mexico: $399 plus $50, $449.

And over three years?

Firstbase in Wyoming reaches $1,096 before Wyoming's own annual charges. Our New Mexico package reaches $647, and New Mexico has no annual report.

Who handles Form 5472?

Firstbase does, if you buy it. The service is $899 a year and covers the 5472, pro forma 1120, 1099s, and an extension for a single-member LLC with a non-US owner. We leave tax filing to your own professional.
