ZenBusiness7 Best LLC Formation Services in South Dakota (July 2026)
1 - ZenBusiness (Best Overall)
Pros and Cons
- Clear checkout with visible support
- Velo AI puts unfinished work in one list
- Paid extras stay unselected
- 100% accuracy guarantee on formation work
- Registered-agent service costs extra on Starter and Pro
Who is it for?
Who is it for?
- First-time owners who want clear filing steps and one list of follow-up tasks.
Who is it not for?
- Owners who need registered-agent service in a low-cost entry package.
The Verdict
ZenBusiness gives most owners the clearest path from checkout to post-filing work.
During our real LLC formation with ZenBusiness, the running total stayed visible throughout checkout. Phone and chat support were easy to find, and paid upgrades were not selected for us.
After payment, Velo AI showed the filing status and checked the account for unfinished EIN, compliance and website tasks. This built-in assistant placed those items in one short list instead of spreading them across the dashboard.
Registered-agent service costs $199 per year with Starter or Pro. Premium includes it, but its higher price will not suit every owner.
ZenBusiness LLC formation packages:
- Starter ($0 + $150 state fee): Articles of Organization filing, standard internal processing and a 100% accuracy guarantee.
- Pro ($199/year + $150 state fee): Adds one-business-day internal processing, an operating agreement, EIN help, Worry-Free Compliance for the first year and a document library.
- Premium ($399/year + $150 state fee): Adds registered-agent service, rush processing, a domain, business email and website tools. The website tools have a 30-day trial and then cost $15 per month.
2 - Northwest Registered Agent (Best for Privacy)
Pros and Cons
- First registered-agent year is included
- Agent details are available after payment
- Dashboard shows the renewal price and date
- Corporate Guides answer filing questions
- Its address cannot replace a real principal address everywhere
Who is it for?
Who is it for?
- Owners who want agent coverage, privacy help and direct support in one order.
Who is it not for?
- Owners who only need the state form submitted.
The Verdict
Northwest combines a useful first-year agent offer with clear human support.
Our Northwest Registered Agent order moved from a clear invoice and confirmation to a review of the company details before filing. Corporate Guides were available when we needed help with the order.
The registered-agent name and address appeared immediately after payment. The dashboard also showed the annual price and next renewal date, making the ongoing cost easy to track.
Northwest can place its address on some public filings where state rules allow it. A bank or other form may still ask for the company's actual principal address.
Northwest LLC formation package:
- Formation ($39 + $150 state fee): Articles of Organization filing and registered-agent service for the first year. Agent service renews at $125 per year.
- Business Identity bundle: Included while agent service stays active. It provides a business address, limited mail scanning, phone service, a domain, hosted website and business email.
3 - Tailor Brands (Best Branding)
Pros and Cons
- Formation and brand tools share one account
- Useful website and social tools for a new launch
- Good fit for customer-facing businesses
- Annual compliance support is available
- Lite is slower, and agent service costs another $199 per year
Who is it for?
Who is it for?
- New owners who need an LLC, website and basic brand materials.
Who is it not for?
- Owners who only want a fast, plain formation filing.
The Verdict
Tailor Brands works best when formation and the customer-facing launch happen together.
Tailor Brands is useful when a first-time owner needs to form the LLC and prepare a public launch. The same account holds the filing status, logo, domain, website builder, digital business card and social tools.
This keeps the legal setup and early brand work together. It can save time when the business needs to look ready for customers soon after approval.
Lite can take up to 14 business days of internal processing. Registered-agent service costs another $199 per year, so filing-only owners may pay for tools they do not need.
Tailor Brands LLC formation packages:
- Lite ($0 + $150 state fee): Articles of Organization filing with internal processing that can take up to 14 business days.
- Essential ($199/year + $150 state fee): Adds faster processing, an operating agreement, annual compliance support and starter branding tools.
- Elite ($249/year + $150 state fee): Adds expanded logo, domain, website, digital business card and social media tools.
4 - LLC Attorney (Best Essentials)
Pros and Cons
- Starter includes core company documents
- Business advisors review filings for accuracy
- Private filing options are available where allowed
- Package details are easy to compare
- Attorney advice and registered-agent service cost extra
Who is it for?
Who is it for?
- Owners who want a strong set of company documents with the filing.
Who is it not for?
- Owners who expect included attorney advice or a broad compliance dashboard.
The Verdict
LLC Attorney is a practical choice when documents matter more than software features.
LLC Attorney includes more company documents than many low-cost filing services. Starter comes with an operating agreement, organizational minutes, a bank resolution and private filing options.
Trained business advisors check the filing for accuracy before submission. Professional adds an EIN, a good-standing certificate, filing changes and tax-election support. Legal advice from an attorney costs extra.
The service stays focused on formation paperwork. Its account has fewer ongoing compliance and business tools than ZenBusiness or Northwest.
LLC Attorney formation packages:
- Starter ($49 + $150 state fee): Articles of Organization filing, an operating agreement, private filing options, organizational minutes and a bank resolution.
- Professional ($199 + $150 state fee): Adds an EIN, Certificate of Good Standing, one amendment or name change and tax-election support.
- International+ ($399 + $150 state fee): Adds a foreign filing or subsidiary formation, an apostille and a Certificate of Incumbency.
5 - LegalZoom (Best Legal Advisor)
Pros and Cons
- Large legal form library
- Attorney consultations on the Premium tier
- Document and eSignature tools
- Useful when legal needs continue after formation
- Post-payment intake and recurring subscriptions add extra steps
Who is it for?
Who is it for?
- Owners who expect to use legal forms or attorney consultations after formation.
Who is it not for?
- Owners who only need a simple filing and low-cost agent service.
The Verdict
LegalZoom works best as a broader legal account, not just a filing tool.
Exclusively for Venture Smarter users, apply code venturesmarter20 to enjoy 20% off LLC formation and other services at LegalZoom.
LegalZoom is most useful when formation is only one part of a wider legal setup. Higher tiers add legal forms, attorney access, eSignature and bookkeeping features.
Our test asked for more company details after payment, so checkout did not finish the intake. Some paid benefits renew as subscriptions, and registered-agent service costs $249 per year.
A simple filing can feel buried in the larger account. LegalZoom makes more sense when you plan to use its legal tools after the LLC is approved.
LegalZoom LLC formation packages:
- Basic ($0 + $150 state fee): Articles of Organization filing, name check and a digital LLC packet.
- Pro ($249 + $150 state fee): Adds an operating agreement, EIN application, business license guide, banking authorization letter, Wix website and phone support.
- Premium ($299 + $150 state fee): Adds attorney review, a 30-minute consultation and 90 days of formation-document changes.
Registered-agent service costs $249 per year.
6 - Inc Authority
Pros and Cons
- No formation service fee
- First registered-agent year is included
- EIN or faster-processing choice can add value
- Digital document storage is included
- Timed upsells and a $249 agent renewal require attention
Who is it for?
Who is it for?
- Careful shoppers who want a low first-year bill and included agent service.
Who is it not for?
- Owners who want a quiet checkout and a detailed follow-up dashboard.
The Verdict
Inc Authority can lower the first bill, but the upsells and renewal need close attention.
Inc Authority kept our first payment low and included registered-agent service for the first year.
Before the final checkout, it asked us to choose one free premium service: an EIN or 24-hour processing. Timed full-screen offers made the order harder to review, so each add-on needs a careful look.
The dashboard has few follow-up tools. Agent service renews at $249 after the first year, which makes the renewal date important to track.
Inc Authority formation options:
- Starter ($0 + $150 state fee): LLC filing, name check, digital document storage and registered-agent service for the first year.
- Paid add-ons: EIN help, an operating agreement, compliance products and faster processing can be added separately. Agent service renews at $249 per year.
7 - Bizee
Pros and Cons
- First registered-agent year is included
- $119 agent renewal is lower than many competitors
- Paid extras stay unselected
- 24-hour order-change window helps catch mistakes
- Some free extras require manual activation after payment
Who is it for?
Who is it for?
- Owners who want a low first-year order with agent service included.
Who is it not for?
- Owners who want every extra activated automatically or documents written by an attorney.
The Verdict
Bizee offers strong first-year value when you are willing to finish a few setup tasks after checkout.
Bizee put each upsell on a separate screen in our formation test. The decline option stayed visible, and paid upgrades were not selected for us.
Basic includes registered-agent service through Republic Registered Agent LLC for the first year. It renews at $119. The account also shows filings, mailbox setup, contracts and compliance tasks.
Some free extras need manual activation, and the templates are not legal advice. A 24-hour order-change window helps if a name, address or member detail was entered incorrectly.
Bizee LLC formation packages:
- Basic ($0 + $150 state fee): Articles of Organization filing, unlimited name searches, registered-agent service for the first year and phone and email support.
- Standard ($199 + $150 state fee): Adds an EIN, IRS Form 2553, operating agreement, bank resolution, compliance notifications, dashboard and business tax consultation.
- Premium ($299 + $150 state fee): Adds contract templates, next-day internal filing, a domain and business email.
How We Picked and Tested the Best LLC Services in South Dakota
We used the same seven-part LLC service testing methodology for every provider: pricing, services, support, filing speed, ease of use, reliability and South Dakota fit. We judged the full order, not only the advertised starting price.
The screenshots below come from a real ZenBusiness formation order. We completed that checkout in another state, so the $35 fee shown in the image is not South Dakota's $150 filing fee.
1. Pricing
We compared provider fees, the $150 online state charge, agent renewals and paid add-ons. A low opening price scored poorly when the ongoing cost was hard to find.
ZenBusiness had the clearest low-cost entry. Northwest and Bizee gained points for including the first year of registered-agent service.
2. Services Offered
We checked the work available after formation, including company documents, EIN help, agent coverage, storage and compliance tools.
Tailor Brands stood out for launch tools. LLC Attorney included a stronger document set, while LegalZoom offered broader legal features.
3. Customer Support
We looked for practical answers about filing, documents, renewals and agent service.
Northwest provided the most direct human help. ZenBusiness used its dashboard to answer many routine next-step questions.
4. Filing Speed
The state controls its review time, but each provider controls when it checks and submits an order. We compared internal processing, order review and delays caused by missing information.
Speed only helped when the order stayed clear. A confusing checkout did not earn extra credit for moving quickly.
5. Ease of Use
We reviewed checkout, document access and the first account login. The strongest services made completed and unfinished work easy to tell apart.
ZenBusiness had the clearest follow-up list. Bizee kept decline options visible, while Inc Authority required more care around timed offers.
6. Reliability and Reputation
We compared public feedback with the prices, package terms and renewals shown during our own tests. A familiar name did not outweigh a difficult order flow.
The highest scores went to services whose account matched what they promised before payment.
7. South Dakota Fit
We considered the filing fee, registered-agent rule and annual report. Services earned more credit when their documents and reminders made those duties easier to manage.
The best option should keep the work clear after the Articles are accepted, not simply submit the first form.

Steps To Creating An LLC In South Dakota
Eight steps stand between you and a formed South Dakota LLC:
- Name the business. Choose a unique name that includes "LLC" or "Limited Liability Company." A name reservation costs $25 if you are not ready to file. Our guide to starting an LLC in South Dakota explains the naming rules.
- Choose a registered agent. The agent needs a physical and mailing address in South Dakota. See our guide to South Dakota registered-agent services if you need one.
- File the Articles of Organization. Submit them to the Secretary of State. Online filing costs $150, while paper filing costs $165.
- Write an operating agreement. You do not file it with the state, but it can set ownership, voting and management rules.
- Apply for an EIN. The IRS issues EINs at no cost. Most US-based applicants can use the online application after the LLC is formed [14].
- Register for taxes and licenses. Your business may need sales-tax, employer or industry accounts.
- Separate business and personal money. Open a business bank account and keep company income and expenses in it.
- Track the annual report. It is due each year on the first day of the LLC's anniversary month and costs $55 online.
Online formations are usually processed immediately, while paper filings average one to three business days. Our LLC formation timeline guide explains what can slow an order down. If you later close the company, follow the steps for dissolving a South Dakota LLC.
