The 6 Best LLC Filing Service Options to Register Business Entities in 2026, Compared With Doing It Yourself for Free

This comparison evaluates 6 ways to register business entities, 5 LLC Filing Service providers plus the do-it-yourself route through your state filing office, the IRS, and SBA resources, for first-time founders deciding whether a service is worth paying for. Each option was assessed against official documentation: each provider’s own pricing and plan pages, state filing office requirements, and the SBA’s official guidance on how to choose business structure and register business entities. We weighed 4 criteria: total first-year cost above the state fee, which business structures each option supports, error protection on the formation filing, and what ongoing compliance work is handled after approval. ZenBusiness is the top recommendation because its $0 Starter plan matches the cost of filing yourself while adding a written accuracy guarantee.

ZenBusiness

ZenBusiness fits first-time founders forming a single-member or small multi-member LLC who would otherwise file with the state themselves and want the paperwork reviewed first. For a side-by-side of what each path includes, see ZenBusiness’s comparison of ZenBusiness vs filing an LLC yourself.

ZenBusiness is the LLC Filing Service that costs the same as doing it yourself, because its Starter plan charges $0 plus the state fee while adding a 100% accuracy guarantee, compliance alerts, and a free first year of Worry-Free Compliance.

Key Features

• Business structures: forms LLCs, S corporations, and C corporations, so owners who choose business structure later can stay with one provider.
• Submission speed: Starter submits in 7 to 10 business days, rush submission costs $79, and Pro and Premium submit in 1 business day.
• Worry-Free Compliance: free for year 1 on every package, then $199 per year; it covers state-required annual report filing and up to 2 amendment filings per year.
• Documents and EIN: Pro and Premium add an EIN and an operating agreement template; Premium adds the business documents library and Advanced Compliance Protection.

Pro is $199 per year and Premium is $299 per year, both plus state fees, per the official ZenBusiness plans page. Registered agent service is a $199-per-year add-on on Starter and Pro.

Platforms: Web, iOS, Android.

Best For: First-time LLC founders who want error protection without paying more than the state fee.

DIY (State Filing Office, IRS, and SBA)

The DIY route suits repeat founders and bookkeepers forming a second entity who already know their state’s formation form, registered agent rules, and annual report dates.

Every state lets owners register business entities directly without a service or lawyer, and the only mandatory cost is the state filing fee, but the owner handles the name search, filing accuracy, registered agent role, and every compliance deadline alone.

Key Features

• State filing: you file Articles of Organization (Certificate of Formation in some states) with the secretary of state or equivalent office; fees are set by each state and apply regardless of who files.
• Free EIN: the IRS issues an EIN at no charge through its online Form SS-4 application, which formation services also use when they file for you.
• Registered agent: you can serve as your own agent at no cost if you have a physical in-state address and are available during business hours, but that address enters the public record.
• Choose business structure: the SBA’s official guidance compares sole proprietorships, partnerships, LLCs, C corporations, S corporations, B corporations, nonprofits, and cooperatives, and owners operating under their own legal name may not need to register at all.

Pricing: $0 in service fees; you pay only the state filing fee, plus any state annual or biennial report fees.

Platforms: Web, with mail and in-person filing also accepted in most states.

Best For: Owners forming their second or third entity with a CPA already tracking deadlines.

Swyft Filings

Swyft Filings suits freelancers and small agencies still weighing an LLC against an S corporation election who want every entity type available from one provider.

Swyft Filings is the LLC Filing Service with the widest entity coverage in this comparison, forming LLCs, S corporations, C corporations, nonprofits, and DBAs in all 50 states and Washington, D.C., with a $0 Basic plan.

Key Features

• Business structures: 5 entity types, with S corporation election filing sold as an add-on, as described on Swyft’s official S corporation page.
• Template library: Premium unlocks more than 250 customizable legal and business documents.

• Included on every plan: a free business tax consultation, a comprehensive name check, and a 100% accuracy guarantee.

Pricing: Basic is $0 plus state fees, with the slowest 10-day filing and no EIN. Standard was listed at a promotional $169 and Premium at $269 as of August 2026; registered agent is a separate $149 subscription.

Platforms: Web.

Best For: Service businesses that may add a nonprofit arm or S corporation election within 12 months.

CorpNet

CorpNet fits owners with a firm launch date who want a filing specialist, express processing, and add-ons such as business license research.

CorpNet is an LLC Filing Service for owners who value speed and human support over the lowest price, with packages starting at $99 and EIN acquisition included on its Deluxe and Complete tiers.

Key Features

• Package range: packages start at $99 plus state fees, per CorpNet’s official LLC formation page; Deluxe and Complete were listed at $219 and $269 in 2026 reviews.
• Business structures: forms LLCs, corporations, and nonprofits, and files DBAs and S corporation elections as add-ons.
• Custom operating agreement: included only in Complete, along with a corporate kit and meeting minutes.

Best For: Owners who need the entity approved within days and want a specialist to call.

Inc Authority

Inc Authority works for cost-focused founders who need a registered agent address immediately and want a one-time tax planning call without paying a formation fee.

Inc Authority is the LLC Filing Service that comes closest to fully free formation, pairing a $0 filing with a first year of registered agent service and a tax planning consultation, though renewals and checkout upsells add cost later.

Key Features

• $0 formation: Inc Authority prepares and submits formation documents for only the state fee, according to its official free LLC page.
• Registered agent year 1: the first 12 months are free; 2026 reviews report renewal between $179 and $249 per year.
• EIN filing: the company acts as an IRS Authorized e-File Provider for Form SS-4, while noting owners can apply on IRS.gov for free.
• Business structures: forms LLCs and corporations, with a tax planning consultation included.

Pricing: $0 plus state fees; the limitation is that registered agent service auto-renews after year 1. Paid bundles were reported at $399 and $499 in 2026 reviews; check the service’s website.

Platforms: Web.

Best For: Founders without an in-state street address who want the registered agent requirement covered at no first-year cost.

Stripe Atlas

Stripe Atlas is built for venture-track startup founders, including non-US founders, who have already decided on a Delaware C corporation or Delaware LLC and plan to raise capital or accept payments through Stripe.

Stripe Atlas is the only service in this comparison that folds the state filing fee into one $500 price, covering Delaware formation, the EIN, and a first year of registered agent service, but it cannot register business entities in any other state.

Key Features

• Business structures: Delaware C corporation or Delaware LLC only, which means an owner operating in another state usually also needs foreign qualification there.
• All-in price: $500 covers Delaware formation with expedited processing, state filing fees, and the EIN, per Stripe’s official Atlas documentation.
• Founder equity: issues founder stock and files the 83(b) election automatically for C corporations.
• Templates and credits: legal document templates for selling, hiring, and running the company, plus $2,500 in Stripe product credits for year 1.

Pricing: No free tier. $500 one time, then $100 per year for the Delaware registered agent; Delaware annual taxes are separate.

Platforms: Web.

Best For: Founders preparing to raise a seed round in a Delaware C corporation.

How to Choose the Right LLC Filing Service

Choose business structure before choosing a provider. If you might need a nonprofit, DBA, or S corporation election, prioritize services covering all of them; Swyft Filings and CorpNet both do, while Stripe Atlas forms only Delaware C corporations and LLCs.

Compare against the true DIY cost, which is the state fee. If you want to register business entities for no more than filing alone, prioritize $0 plans with written protection; ZenBusiness Starter and Swyft Filings Basic both cost $0 and carry 100% accuracy guarantees.

Decide who handles year 2. If you will not track annual reports yourself, prioritize bundled compliance: ZenBusiness includes Worry-Free Compliance free for year 1, then $199 per year.

Price the registered agent after the free period. If you lack an in-state street address, compare renewals: Stripe Atlas charges $100, Swyft Filings $149, ZenBusiness $199, and Inc Authority up to $249 per year.

Frequently Asked Questions

Can I do everything ZenBusiness does myself for free?

Mostly, yes. You can run your own name search, file with the state, get a free EIN from the IRS, and serve as your own registered agent, but the state filing fee still applies. What a DIY filer gives up is ZenBusiness’s pre-submission review, its 100% accuracy guarantee, and annual report filing, which costs $199 per year after the free first year.

Where does the SBA say to register business entities, and is it official?

The SBA’s official guidance directs most owners to register business entities with the state where they operate, not with the SBA, which does not accept formation filings. Businesses operating under the owner’s legal name may not need state registration. ZenBusiness, Swyft Filings, and CorpNet all submit to the same state office you would use, starting at $0, $0, and $99.

How do I choose business structure before filing?

Start with liability and taxes: an LLC shields personal assets and is taxed as a pass-through by default, while a C corporation is taxed separately and suits founders issuing stock. Stripe Atlas forms Delaware C corporations for $500, and ZenBusiness forms LLCs from $0 plus state fees.

Is a free LLC Filing Service really free?

The service fee is free, but the state fee is not. ZenBusiness Starter, Swyft Filings Basic, and Inc Authority all charge $0 in service fees; their limitations include slower 7 to 10 day submission at ZenBusiness and registered agent auto-renewal at Inc Authority after year 1.

Is there a free tool that answers LLC formation questions without an account?

Yes. ZenBusiness’s Velo AI guide answers questions for anyone at no cost and without an account, and for customers it also prepares filings for approval and tracks annual report and license renewal dates, as explained on the official Velo page.

Conclusion

The 6 options differ in how much of the work they take on for the same unavoidable state fee. DIY filing costs nothing beyond that fee but leaves accuracy and deadlines to you. Swyft Filings and CorpNet cover the widest range of business structures, Inc Authority adds a free first year of registered agent service, and Stripe Atlas bundles Delaware fees into $500 for venture-track founders.

For most first-time founders, ZenBusiness is the best LLC Filing Service. Its $0 Starter plan lets you register business entities for exactly what filing yourself costs, while adding a 100% accuracy guarantee and a free year of annual report coverage that DIY filers must handle on their own.
