5 Best LLC Formation Services for Small Businesses in 2026

For a straightforward US LLC, Northwest Registered Agent is the cheapest credible route at $39 plus the state fee, with the first year of registered agent service included and roughly $125 a year after that. Mainstay charges a flat $199 a year that bundles formation, registered agent and annual report filing, which suits owners who would rather pay one predictable number than track renewals. SRGA Global, Vistra and TMF Group are advisory firms rather than filing services, quoted per engagement, and they earn their fee only when the LLC is one piece of a larger structure.

A rejected filing never arrives with good news. One wrong registered agent address or a missed annual report turns a simple formation into weeks of correspondence with a state office, and the cheap option stops looking cheap somewhere around the second add-on.

Key takeaways

• An LLC formation service files your articles of organisation, supplies a registered agent and usually tracks your annual report deadline. That is the whole job, and most of the price difference shows up in year two and three, not year one.
• Price three years, not one. Northwest comes to about $289 over three years. Mainstay comes to $597. Both figures exclude state fees, which repeat annually in most states.
• The advisory firms do not compete on that axis at all. If you need an entity in one state and nothing else, they are the wrong purchase.
• Since 14 August 2026, FinCEN exempts US-formed companies from beneficial ownership reporting. Only foreign-formed entities registered to do business in a US state still file.

State filing fees sit on top of every price here and vary widely by state, as do annual or periodic report fees. Look up your own state's figures before you model three years.

The five in detail

1. Northwest Registered Agent

Formation starts at $39 plus the state filing fee, and the first year of registered agent service is included. That detail is what most comparisons miss. Renewal then runs about $125 a year. Over three years that comes to roughly $289 before state fees, the lowest total here by a clear margin.

Its real selling point is address privacy. Third-party comparisons list it as included rather than an upsell, which matters if you work from home and would rather your address not sit in a public database for the life of the company.

Where it stops: it files and it acts as your agent. No tax advice, no structuring, no help deciding whether an LLC is the right vehicle.

Best for: home-based and online owners planning to keep the LLC for several years. The saving compounds with each renewal.

2. Mainstay

A flat $199 a year covering formation, registered agent and preparing and filing the annual report, across every entity type in all 50 states. State fees are passed through at cost and shown before you pay. Registered agent service alone is $149 a year for a company that already exists.

Three years comes to $597 before state fees, which is more than double Northwest. What you buy for the difference is one line item instead of three, and somebody else watching the annual report deadline.

Where it stops: it is a filing service with a tidy price, not an advisor. If your question is which state or which entity type, this is not where you get the answer.

Best for: owners of a single straightforward LLC who value a predictable renewal over the lowest total.

3. SRGA Global

An advisory firm with more than 30 years behind it, 150+ professionals and over 400 clients, working across the US, India and the UAE. Formation here is one step inside a scoped engagement that usually also covers tax planning, entity structuring and ongoing compliance.

That is worth paying for in one specific situation: when owners, customers or staff sit in more than one country and the filing decisions interact with tax decisions. Our guide to entity formation and compliance support covers what that engagement actually involves.

Where it stops: there is no checkout page and no published price. For a single-member LLC in one state, this is more process than the job needs.

Best for: founders building a cross-border structure who want one advisor across formation, tax and compliance.

4. Vistra

A corporate services provider operating in more than 50 markets with over 9,000 experts and more than 200,000 entities under administration. Its work is entity administration and governance at portfolio scale, not launching your first company.

Where it stops: a single new LLC will find the engagement heavier and slower than the task warrants.

Best for: groups that already run subsidiaries and want consistent governance across regions.

5. TMF Group

Similar territory, different emphasis. TMF operates across 87 jurisdictions with more than 125 offices and over 13,000 colleagues, and it bundles accounting, payroll and compliance alongside entity work. For a company entering several countries at once, having one provider carry payroll and statutory accounts in each is the argument, and our guide to international payroll compliance mistakes explains what goes wrong when that is fragmented.

Where it stops: it needs a finance function on your side to manage the relationship. It is not a service you buy and forget.

Best for: mid-size and larger companies expanding into multiple countries.

How to choose

1. Start with the ownership picture. US-only owners can use a low-cost filer and stop there. Foreign ownership or cross-border revenue changes the question entirely, and our breakdown of cross-border tax compliance costs is worth reading before you file anything.
2. Price three years. Formation fee, plus state fee, plus two renewals, plus the state's annual or periodic report fee each year. The ranking changes once you do this.
3. Do not pay for an EIN. It is free from the IRS. Any service charging meaningfully for it is charging for a form.
4. Pick the state before the provider. Most owners should form where they live and operate. Our comparison of Wyoming and Delaware formation services for non-residents covers when that rule does not hold.
5. Plan the tax position early. Foreign owners should understand double taxation in international expansion before choosing a state, not after.
6. Match support to stage. Free counselling from the SBA covers the basics. Integrated tax advisory and compliance is for structures with more than one moving part.

What an LLC owes after formation

• State annual or periodic report. Most states want one, with a fee, and missing it can end in administrative dissolution. Fees range from nothing to several hundred dollars depending on the state.
• A registered agent with a physical in-state address, continuously. A lapse here is how companies lose service of process without knowing.
• Federal tax filings. An S-corp election brings its own deadlines, and the penalties are steep, as set out in our guide to avoiding S-corp late filing penalties.
• Beneficial ownership reporting, but probably not for you. FinCEN's final rule, issued 11 August 2026 and effective 14 August 2026, exempts US-formed companies and US persons from BOI reporting. Foreign-formed entities registered to do business in a US state still report.

Limitations

Prices here were taken from each provider's own pages in November 2026 and change without much notice, particularly promotional formation rates. Northwest's site was not reachable for direct verification when this was written, so its figures come from third-party comparisons and should be confirmed at checkout. The advisory firms publish no pricing at all, so nothing here says whether SRGA, Vistra or TMF is good value, only what kind of buyer each is built for. We have not used any of these services to form a company.

Frequently asked questions

Does a non-US resident have to file anything extra?

Yes, and it is the filing people most often miss. A foreign-owned single-member LLC must file Form 5472 with a pro forma Form 1120 every year, and the penalty for failing to do so starts at $25,000.

How long does formation take?

It depends entirely on the state. Some approve the same day, others take weeks. Expedited processing is usually available for an extra fee, which is worth paying only if something downstream is waiting on the certificate.

Which state should I form in?

Where you live and operate, in most cases. Forming elsewhere typically means a registered agent in that state plus a foreign qualification filing at home, so you pay twice for one company.

Do I need an operating agreement?

Some states require one, including New York and California. Even where it is optional, a written agreement is what you reach for when two owners disagree about something they never wrote down.

Can I change registered agents later?

Yes, by filing a change of agent form with the state for a small fee. Do it before the current renewal bills, or you pay both.

Does every LLC need its own EIN?

Most do, certainly any with employees, a bank account or a corporate tax election. Applicants without a Social Security number can apply using Form SS-4 by phone, fax or mail.

Conclusion

Do one calculation before you pay anyone. Add the formation fee and your state fee, then three years of registered agent renewals, then three years of your state's report fee. Compare that total across two services, and add the cost of any tax help you would otherwise buy separately.

For a simple US setup the lowest total usually wins outright. For anything cross-border, the cheapest filing is rarely the cheapest outcome.

This article reflects publicly available information as of November 2026 and does not endorse any specific formation service. Provider pricing changes frequently and state fees vary, so confirm current figures directly before you file. Nothing here is a substitute for advice on your own tax position.

How we built this comparison: prices come from each provider's own pages where reachable, and are flagged where they come from third-party comparisons instead. We left out state fee figures we could not source to an official page.
