LLC formation services promise to set up a US company for you in days, often with a registered agent, an EIN and bank access included. Choosing one is less about the lowest sticker price and more about what the package really covers and whether it understands your Spanish tax situation.
The short answer: compare providers on what is included (state filing, registered agent, EIN, operating agreement, banking introductions), what is charged every year, how they handle compliance reminders and whether they offer or recommend tax advice for a Spanish resident. Check current prices and terms on each provider’s own site, because they change often.
This guide does not rank or endorse specific providers and quotes no prices, which change often. Some providers pay referral commissions, so check independent reviews. It is general information, not legal or tax advice.
Key takeaways: LLC formation services
- The best LLC formation services are clear about what is included and what is charged each year.

- Check the registered agent terms, because you must keep one for as long as the LLC exists.
- Ask about the EIN process for foreign owners and about banking support.
- Compare total cost over several years, not only the first-year price.

What LLC formation services usually do
A formation service handles the paperwork of creating your LLC in a state. Typical steps are checking name availability, filing the articles of organization, appointing a registered agent, drafting an operating agreement and applying for an EIN. Some services also offer mailbox addresses, compliance reminders, bank introductions and bookkeeping.
Types of LLC formation services
| Type | Examples of what they offer | Best for |
|---|---|---|
| Online all-in-one platforms | Formation, EIN, agent, banking introductions, dashboard | Founders who want a quick, guided process |
| Registered agent companies | State filing and registered agent, with optional extras | Owners who want a stable agent and do the rest themselves |
| Law firms and tax advisers | Formation with legal and tax advice, including cross-border structuring | Owners with complex needs or higher income |
| Do-it-yourself with the state | You file directly and appoint an agent | Owners who accept more paperwork to save fees |
What to compare in LLC formation services
- Price structure: formation fee, state fee, registered agent fee and renewal fees.
- State options: whether they support the state you want. See Wyoming vs Delaware vs New Mexico LLC.
- EIN for foreign owners: who handles it and how long it takes. See registered agent and EIN explained.
- Banking support: whether they help with bank or fintech accounts. See LLC bank account without living in the US.
- Compliance: reminders for annual reports and US forms.
- Tax guidance: whether they understand the Spanish and US tax duties, or leave you on your own.
- Contract terms: auto-renewal, cancellation and how to transfer the LLC or agent.
- Reputation: independent reviews and how they handle support issues.
Hidden costs to watch for
- A low first-year price followed by a higher renewal.
- Extra fees for the EIN, the operating agreement or expedited processing.
- Charges for mail forwarding or document handling.
- Fees for annual report filing on top of the state fee.
- Upsells for tax filings that you may not need, or that do not cover Spain.
- Currency conversion and payment fees.
Spanish tax: what LLC formation services do not cover
A service that forms your LLC has done its job when the LLC exists. It normally does not decide how Spain will tax you, whether the LLC will be considered Spanish-resident, or how to report foreign accounts. These topics need a Spanish adviser: read LLC taxation in Spain for resident owners and modelo 720. Before you pay for any formation, read LLC for freelancers in Spain: pros, cons and costs.
Questions to ask before you pay
- What exactly is included in the price, and what is charged annually?
- Which registered agent do you use, and can I change agents later?
- Do you handle the EIN for a foreign owner, and how long does it take?
- Which bank accounts can I open, and do I need to travel?
- Who files my annual report and US forms, and at what cost?
- Can I export my documents and leave without penalty?
- Do you have experience with owners who live in Spain?
Do-it-yourself or use a service?
You can form an LLC directly with the state for the filing fee and appoint a registered agent yourself. It takes more time and knowledge but may lower the cost. A service is more convenient and often includes support, but costs more over time. If your situation is complex, consider an adviser rather than a mass-market platform.
Common mistakes to avoid
- Choosing the cheapest first-year price without checking renewals.
- Assuming the provider handles Spanish tax.
- Not checking who owns the registered agent relationship.
- Forming the LLC before deciding whether it is the right structure.
- Ignoring annual compliance and missing deadlines.
- Relying on affiliate-driven rankings.
Frequently asked questions about LLC formation services
What do LLC formation services include?
Usually the state filing, a registered agent, an operating agreement and an EIN application, with optional extras such as banking introductions and compliance reminders.
Are LLC formation services worth it?
They save time and reduce paperwork errors, but cost more than forming the LLC yourself. Compare the total multi-year cost.
Do they handle Spanish taxes?
Most do not. You need a Spanish tax adviser for the Spanish side.
Can I form an LLC without a service?
Yes. You can file directly with the state and appoint a registered agent yourself.
How long does it take?
It depends on the state and the provider. The EIN for a foreign owner can take longer than the state filing.
Can I change providers later?
Usually yes, but check how to transfer the registered agent and documents before you sign.
Final thoughts on LLC formation services
When you choose among LLC formation services, look beyond the price: check what is included, how renewals and the registered agent work, how the EIN is handled for a foreign owner and what happens with compliance. Remember that the provider forms the company but does not solve your Spanish tax. Compare total costs over several years, read independent reviews and decide whether you need an LLC at all.
