Firstbase.io Features: What Does It Offer?
1. U.S. Company Formation
Firstbase.io helps you register an LLC or C-Corp in Delaware or Wyoming. Startups prefer these states due to their low taxes, business-friendly laws, and strong privacy protections.
2. EIN (Employer Identification Number) Application
An EIN (Tax ID) is required to open a U.S. business bank account, hire employees, and file taxes. Firstbase.io handles the entire EIN application process, ensuring compliance with IRS requirements.
3. U.S. Business Banking Support
Opening a U.S. business bank account remotely can be challenging for international founders. Firstbase.io partners with banks like:
- Mercury (ideal for startups and tech companies)
- Relay (great for cash management and international businesses)
- Brex (best for venture-backed startups)
4. Virtual Mail Room
Firstbase.io provides a U.S. business address, which is essential for official correspondence, banking, and tax filings. The mailroom service scans and forwards important documents, but it has mixed reviews (more on this later).
5. Compliance & Annual Reports
Staying compliant is critical for any business. Firstbase.io offers a Compliance Autopilot service, which helps manage:
- Annual reports & filings
- Franchise taxes
- Registered agent services
This is helpful because failing to file can lead to penalties or business dissolution.

Pros: Why Use Firstbase.io?
- Simple & Easy Process – No need to deal with complex paperwork. Firstbase.io guides you step-by-step.
- Best for International Entrepreneurs – Many incorporation services cater to U.S. citizens only, but Firstbase.io is built for global founders.

Cons: What You Should Consider
