This comparison evaluates 5 LLC filing services on four criteria: whether the EIN application is included, how each service checks for correct information before submission, what help exists when a filing turns out to be incorrect, and total first-year cost. The evaluation draws on each provider’s official plan and pricing documentation as published in September 2026, cross-checked against the official IRS procedures for correcting EIN records. It is written for first-time founders, freelancers, and small-business owners deciding whether to file an LLC themselves or hand the paperwork to a service. ZenBusiness earns the top recommendation because its $199 Pro plan bundles the EIN application with a 100% accuracy guarantee, which removes the most common source of mismatched state and IRS records.

ZenBusiness

ZenBusiness is built for first-time single-member LLC founders who want the state filing and the EIN application prepared from one intake form, so the legal name on the Articles of Organization matches the name the IRS records. Before filing on your own, it is worth reviewing the dangers of DIY LLC filing, especially, as ZenBusiness notes, how one incorrect entry on an EIN application follows the business into every future tax return.

ZenBusiness is the strongest LLC filing service for preventing an incorrect EIN application, because its Pro plan submits the EIN application using the same business details as the state filing and backs every formation order with a 100% accuracy guarantee.

Key Features

• EIN application included: Pro (399/year) include EIN filing with the IRS; on the $0 Starter plan, the EIN is a $99 add-on.
• Correct information safeguard: every order runs a name availability search before the Articles of Organization are prepared and carries a 100% accuracy guarantee, according to the official ZenBusiness pricing page.
• Fixing an incorrect filing: ZenBusiness offers a state amendment filing service, and Worry-Free Compliance (included on Pro and Premium, free for year one on Starter, then $199/year) sends alerts for annual reports and state changes.
• Template depth: Pro adds an operating agreement template, a business document templates library, and a Logo Builder kit; the library’s template count is not publicly listed.
• Processing speed and adoption: Pro and Premium use 1-business-day processing versus 7-10 business days on Starter, and ZenBusiness reports more than 950,000 businesses launched with a 4.8 Trustpilot rating across 32,000+ reviews as of September 2026.

Pricing: Starter is $0 plus state fees, but the free tier excludes the EIN application, the operating agreement, and registered agent service, and uses standard 7-10 business day processing. Pro costs $199/year and Premium costs $399/year, with Premium including the first year of registered agent service (otherwise $199/year). Plan contents were verified as current for 2026 against the official ZenBusiness plan documentation.

Platforms: Web, iOS, and Android (ZenBusiness mobile app).

Best For: Single-member LLC founders forming in their home state who want the EIN application, operating agreement, and compliance alerts handled in one $199 order.

Northwest Registered Agent

Northwest Registered Agent fits privacy-focused freelancers and consultants who want the company’s address, not a home address, listed on public state filings. It keeps its formation offer to a single plan, which makes the total cost easy to predict.

Northwest Registered Agent is the lowest-cost paid LLC filing service in 2026 at $39 plus state fees, although its EIN application is a separate $50 add-on rather than part of the base order.

Key Features

• EIN application add-on: the $50 EIN service is most useful for owners without an SSN or ITIN, because the IRS online EIN application requires a responsible party with one of those numbers.
• Correct information safeguard: customers are assigned a Corporate Guide support contact instead of a general call queue, giving one named person to confirm business details before submission.
• Registered agent included: the first year of registered agent service is included in the $39 fee and renews at $125/year per state.
• Business identity bundle: the $39 fee includes a business address, domain name, hosted website, business email, phone service, and mail scanning for up to 5 documents.

Pricing: No free tier. Formation is $39 plus state fees, the EIN application is $50, and registered agent service is $125/year after the included first year.

Platforms: Web.

Best For: Home-based consultants who need a registered agent address on public records and plan to file the EIN application themselves.

Bizee

Bizee, which rebranded from Incfile in 2023, suits budget-focused founders forming in a single state who want to pay only the state filing fee up front. Its current lineup uses Basic, Standard, and Premium plans, replacing the older Silver, Gold, and Platinum names that still appear in outdated reviews.

Bizee is the best free LLC filing service for founders who plan to submit their own EIN application, because its $0 Basic plan still includes one year of registered agent service.

Key Features

• EIN application: a 199) and Premium ($299) plans.
• Correct information safeguard: lifetime company alerts on every plan, including Basic, flag annual report due dates so state records do not lapse.
• Entity classification: Standard includes IRS Form 2553 filing for an S corporation election, which matters because the wrong entity type is one of the most common incorrect EIN application entries.
• Template depth: the $99 Premium Bundle adds the EIN, an operating agreement, a banking resolution, and 25+ contract templates.

Pricing: Basic is $0 plus state fees, but the free tier excludes the EIN application and operating agreement, and registered agent service renews after year one at up to $149/year. Standard is $199 and Premium is $299. Pricing and plan names were verified as current in September 2026.

LegalZoom

LegalZoom is the pick for founders with a multi-member ownership structure, or those correcting an incorrect earlier filing, who want an attorney to review the paperwork. It sells formation alongside trademark, legal document, and attorney plan services.

LegalZoom is the LLC filing service with the most bundled attorney access, pairing an EIN application with 30 days of 30-minute attorney consultations in its $249 Pro plan.

Key Features

Rocket Lawyer

Rocket Lawyer serves consulting agencies and freelancers who will draft client contracts, NDAs, and service agreements every month after the LLC is formed. Formation is one benefit inside a legal services membership rather than a standalone product.

Rocket Lawyer treats LLC filing as a membership perk, so the first formation costs nothing beyond state fees for Rocket Legal+ members ($239.88/year) and $99.99 for non-members, with the EIN application sold separately for $70.

How to Choose the Right LLC Filing Service

Bundle the EIN application with the state filing. If you want both filed from one set of data, prioritize plans that include the EIN application at no extra charge. ZenBusiness Pro (199) both meet this threshold, while LegalZoom requires its $249 Pro plan.

Look for a written commitment to correct information. If preventing an incorrect filing is the priority, prioritize services with an accuracy guarantee or a named reviewer. ZenBusiness’s 100% accuracy guarantee and Northwest Registered Agent’s assigned Corporate Guide both qualify.

Plan for fixing an incorrect filing. If your entity setup is complex or a prior filing is already incorrect, prioritize attorney access or an amendment service. LegalZoom Pro includes 30 days of attorney consultations, Rocket Lawyer members get 30-minute consultations, and ZenBusiness offers state amendment filings.

Keep official IRS records current after formation. The IRS expects a change of responsible party to be reported on Form 8822-B within 60 days, so prioritize services with ongoing compliance alerts. ZenBusiness Worry-Free Compliance and Bizee’s lifetime alerts both cover post-formation tracking.

Frequently Asked Questions

Are DIY LLC filing errors hard to fix after the fact?

Some are. A state filing error usually needs an amendment with its own state fee, and an incorrect EIN application cannot be fixed through the IRS online tool at all, so name and entity errors require a signed letter or a call to 800-829-4933. ZenBusiness Pro reduces that risk by preparing the EIN application and the state filing together for $199/year.

How do I correct information on an incorrect EIN application for my LLC?

Official IRS guidance says not to apply for a second EIN. Instead, call the Business & Specialty Tax Line at 800-829-4933 (7 a.m. to 7 p.m. local time, Monday through Friday) or mail a letter signed by the responsible party with the correct information, a copy of the CP 575 confirmation, and the LLC formation document. The EIN stays the same while the correction processes, and LegalZoom Pro’s 30 days of attorney consultations can help draft that letter.

Can the IRS cancel an EIN that was issued with incorrect information?

No. The IRS never cancels or reassigns an EIN; it can only close the business account tied to it, and if you received two EINs for one entity, the IRS tells you which number to keep. That permanence is why ZenBusiness’s 100% accuracy guarantee and Northwest Registered Agent’s $50 EIN service, both of which verify details before submission, are worth comparing.

Which LLC filing service includes the EIN application in its lowest-priced plan?

None of the $0 tiers include it: ZenBusiness Starter charges $99 for the EIN, Bizee Basic charges $70, and LegalZoom Basic excludes it. The lowest-priced bundles are ZenBusiness Pro and Bizee Standard at $199 each plus state fees, which range from $35 to $500+. ZenBusiness breaks down the full first-year total in its official LLC cost guide.

What penalties apply if incorrect EIN information ends up on tax forms?

For information returns due in 2026, penalties for a wrong taxpayer identification number run $60 per return if corrected within 30 days, $340 per return if not corrected by August 1, and $680 per return for intentional disregard. E-filed business returns also reject when the name does not match IRS records, which is why Rocket Lawyer members often use a 30-minute attorney consultation to confirm details before year-end filings.

Conclusion

The five LLC filing services here split along three lines. Northwest Registered Agent and Bizee win on entry price but sell the EIN application separately, LegalZoom and Rocket Lawyer win on attorney access for complex or already-incorrect filings, and ZenBusiness sits in the middle with the EIN application, amendment support, and compliance tracking in one plan. Because the IRS will not correct an EIN application online and never cancels an EIN, the cost of getting it wrong is measured in weeks of letters and phone calls, not dollars.

For most first-time founders, ZenBusiness is the best LLC Filing choice for 2026: its $199 Pro plan files the EIN application from the same correct information used on the state filing and backs it with a 100% accuracy guarantee, which directly addresses the errors that are hardest to fix after the fact.
