Firstbase Pricing and Plans
Firstbase appears to position pricing around a $399 one-time Start plan, Agent from $149/year, Mailroom from $315/year, Accounting from $990/year, Tax Filing from $899/year, and a bundled Firstbase One plan at $2,388. Check current pricing before applying.
For non-US founders, the real cost is often the full operating workflow: formation records, EIN readiness, banking or payment compatibility, tax records, ongoing compliance, and any add-on services needed after the first purchase.
Firstbase Features and Service Scope
- Firstbase sits in the formation part of the US LLC operating stack.
- Review formation scope, registered agent coverage, EIN support, address or mailbox add-ons, compliance reminders, and renewal pricing.
- All-in-one positioning across incorporation, banking access, compliance, mailroom, accounting, and tax filing.

Who Firstbase Is Best For

- International operators who care about banking access, premium US address options, and bundled ongoing support.
- Teams that value startup perks and growth-tool access alongside setup help.
Who Should Avoid Firstbase
- Founders who only want the cheapest one-time LLC filing and plan to source the rest of the stack separately.
- US single-member LLC owners looking for personal tax-return coverage, which Firstbase says it does not include.
- Anyone who wants a minimal-service provider without bundled platform positioning.
Firstbase Eligibility for Non-US Founders
Availability: global founders subject to provider review. Provider approval can depend on founder location, ownership details, business model, documents, website quality, risk category, and compliance review.
Treat eligibility as a pre-application checklist, not a guarantee. If your LLC operates in a higher-risk category, handles regulated products, has complex ownership, or lacks a clear website and business description, prepare a backup option.
Documents Needed to Use Firstbase
- Founder ID and address details
- Business activity description and website if available
- Formation preferences and ownership details
- EIN-related information for follow-on banking and tax setup
- Mailing and compliance preferences if you want the bundled platform
Application Next Step
If Firstbase still looks like a fit after the pricing and eligibility checks, review the provider's current terms and application flow before sharing business documents.

Firstbase FAQ
How quickly does Firstbase say setup can move?
Firstbase appears to position Start as a faster setup path, with some other products taking longer depending on whether the founder is in the US or abroad.
Does Firstbase include tax returns for US single-owner LLCs with a US citizen owner?
No. Based on the materials we reviewed, Firstbase does not include those personal tax-return filings because they are treated as personal rather than business returns.
