How to Form a South Dakota LLC as a Non-Resident: Complete Guide for 2026

If you are a non-US resident planning to start an Amazon, e-commerce, or other online business in the United States, South Dakota can be an interesting state to consider for your LLC.

South Dakota has no individual state income tax, relatively simple annual compliance, and comparatively low ongoing state costs. For international entrepreneurs who do not necessarily need a physical presence in a major state such as Texas or Florida, these features can make South Dakota worth looking at.

However, forming an LLC in South Dakota does not mean your business becomes completely tax-free. Sales tax, federal tax filings, annual reports, and other compliance requirements can still apply.

In this guide, we will explain how a non-resident can form a South Dakota LLC, the formation requirements, annual compliance, federal tax considerations, sales tax requirements, and whether South Dakota can be a suitable state for an Amazon or e-commerce business.

Can a Non-Resident Form an LLC in South Dakota?

Yes. You do not need to be a US citizen or US resident to form and own a South Dakota LLC.

A non-resident entrepreneur can generally establish the company without living in South Dakota or travelling to the United States.

For international entrepreneurs, the common business structures include:

• Single-member LLC

• Multi-member LLC

• C-Corporation

The structure you choose should depend on your ownership, business activities, tax situation, and long-term plans.

What Is Required to Form a South Dakota LLC as a Non-Resident?

South Dakota does not require you to personally live in the state. However, there are still some important requirements that must be completed when establishing the company.

1. South Dakota Registered Agent

Every South Dakota LLC must maintain a registered agent with a physical address in South Dakota.

The registered agent receives official notices and legal correspondence on behalf of your company.

For a non-resident owner, this is particularly important because you may be operating your business completely from outside the United States.

You do not necessarily need your own physical address in South Dakota, but your registered agent must meet the state's requirements.

2. Articles of Organization

To establish a South Dakota LLC, Articles of Organization must be filed with the South Dakota Secretary of State.

This filing officially creates your LLC and includes important information about the business.

For a domestic South Dakota LLC, the online state filing fee is generally $150.

3. EIN

Once your LLC has been formed, you will generally need an Employer Identification Number (EIN) from the IRS.

An EIN is commonly required for:

• US business banking

• Federal tax filings

• Payment processors

• Amazon and other business platforms

• Hiring employees, if applicable

• Other business and financial requirements

Non-US residents can obtain an EIN even without being US citizens or residents, although the process can be different when the owner does not have a US taxpayer identification number.

4. Operating Agreement

An Operating Agreement explains the ownership and management of your LLC.

For a single-member LLC, it can help document how the business is structured and operated.

For a multi-member LLC, it becomes even more important because it can define ownership percentages, responsibilities, management authority, and how profits and losses are handled.

How Much Does It Cost to Form a South Dakota LLC?

The state filing fee to form a South Dakota LLC online is generally $150.

However, the state filing fee is only one part of the total setup cost.

Depending on your requirements, you may also have expenses for:

• Registered agent service

• US business address

• EIN assistance

• Mail handling

• Business banking assistance

• Tax preparation

• Sales tax registration and filing

• Other business services

When comparing different states, non-resident entrepreneurs should consider both the initial formation cost and the ongoing annual cost of maintaining the LLC.

How Long Does It Take to Form a South Dakota LLC?

Processing time can vary depending on the filing method and the current workload of the state.

In general, formation can take anywhere from a few business days to a few weeks depending on the circumstances.

The complete setup may take longer if you also need to obtain an EIN, arrange a business address, open a business bank account, or complete other requirements after formation.

South Dakota LLC Annual Compliance Requirements

Once your LLC has been formed, you need to keep it compliant.

Fortunately, South Dakota's state-level LLC maintenance is relatively straightforward compared with some other states.

South Dakota Annual Report

South Dakota LLCs are required to file an Annual Report with the South Dakota Secretary of State.

The annual filing fee is generally $50.

The report is normally due by the last day of the anniversary month in which your company was formed.

For example, if your LLC was formed during September, its annual report would generally be due by the end of September in subsequent years.

Filing your Annual Report on time helps keep the company in good standing.

Does South Dakota Have a Franchise Tax?

South Dakota does not impose a general state franchise tax on LLCs.

This is one reason the state can be attractive to entrepreneurs who want relatively simple state-level compliance.

Does South Dakota Have State Income Tax?

South Dakota does not impose an individual state income tax.

The state also does not have a general corporate income tax of the type imposed by many other states, although particular industries and activities can have separate tax requirements.

For many ordinary LLC owners, this makes South Dakota's state tax environment relatively straightforward.

However, no South Dakota income tax does not mean no US tax obligations.

Federal taxation is a separate matter and depends on your LLC structure, ownership, income, and business activities.

Federal Tax Requirements for a Foreign-Owned South Dakota LLC

Non-resident entrepreneurs should pay particular attention to federal tax compliance.

A foreign-owned single-member LLC that is treated as a disregarded entity for federal tax purposes can have an information reporting requirement involving Form 5472 and a pro forma Form 1120 when the applicable reporting conditions are met.

Form 5472 is particularly important because failure to file correctly can result in substantial penalties, with the basic penalty starting at $25,000.

Depending on your income and activities in the United States, additional federal tax returns may also be required.

Multi-Member LLC

A multi-member LLC is generally treated as a partnership for federal tax purposes unless another tax classification is elected.

This can involve:

• Form 1065

• Schedule K-1 for each partner

• Additional tax filings for non-resident partners where applicable

Can a Non-Resident LLC Elect S-Corp Status?

Generally, a non-resident alien cannot be a shareholder of an S-Corporation.

Therefore, foreign entrepreneurs should not assume that they can simply form an LLC and make an S-Corp election.

Your federal tax structure should be considered according to your actual ownership and business circumstances.

South Dakota Sales Tax for E-Commerce Businesses

South Dakota has sales tax, so e-commerce businesses need to understand whether they have an obligation to register, collect, and remit it.

The state sales tax rate is currently 4.2%, with applicable municipal taxes potentially increasing the total rate.

For an e-commerce seller, the important question is whether the business has established sales tax nexus in South Dakota.

Nexus can arise from factors such as:

• Physical presence

• Inventory

• Employees or other business operations

• Economic activity exceeding the applicable state threshold

South Dakota is particularly important in US e-commerce tax history because the state was involved in the South Dakota v. Wayfair case, which changed how states can apply sales tax obligations to remote sellers.

Today, remote sellers should pay attention to their sales activity in each state rather than assuming they are exempt simply because they do not have a physical office there.

South Dakota Economic Nexus

South Dakota's economic nexus rules are particularly relevant to online sellers.

The current economic nexus threshold is generally based on exceeding $100,000 in gross sales into South Dakota during the previous or current calendar year.

Older information may still mention a separate 200-transaction threshold. That transaction-count test was removed from South Dakota's economic nexus law, so sellers should make sure they are working with current requirements.

For Amazon sellers, there is another important consideration.

Amazon and other marketplaces may collect and remit sales tax as marketplace facilitators. However, marketplace collection does not automatically mean that every possible registration or filing obligation disappears.

Your complete business activities should be considered before deciding what you need to file.

South Dakota Sales Tax Filing Requirements

If your business is registered for South Dakota sales tax, the South Dakota Department of Revenue will determine your filing requirements.

Your filing frequency may depend on your tax liability and account.

When filing, you may need to report information such as:

• Gross sales

• Taxable sales

• Exempt sales

• Sales tax collected

• Marketplace sales

• Applicable local sales

• Other information required on your return

The filing frequency and exact due date should always be checked against the schedule assigned to your business.

Keeping your sales data properly organized throughout the year can make filing much easier.

South Dakota LLC vs Florida LLC for Non-Resident E-Commerce Sellers

Both South Dakota and Florida have no individual state income tax, but there are some major differences in their formation costs, annual requirements, market size, and overall business environment.

Feature	South Dakota LLC	Florida LLC
Non-Resident Ownership	Allowed	Allowed
Individual State Income Tax	None	None
General Corporate Income Tax	No general corporate income tax	Corporate income/franchise tax can apply to corporations and LLCs taxed as corporations
Domestic LLC State Filing Fee	Generally $150 for online filing	Generally $125
Annual LLC Filing	Annual Report required	Annual Report required
Annual Report Fee	Generally $50	$138.75
General Franchise Tax on LLCs	None	No separate general LLC franchise tax
State Sales Tax	4.2% state rate, plus applicable municipal taxes	6% state rate, plus applicable county surtax
Economic Sales Tax Nexus	Generally more than $100,000 in South Dakota sales	Generally more than $100,000 in taxable remote sales into Florida during the previous calendar year
Privacy	Can offer relatively limited public disclosure depending on management structure and filings	More business information can be publicly available
Market Size	Smaller domestic market	Much larger consumer and business market
Best Suited For	Entrepreneurs looking for relatively low annual state costs without needing a large local market	Businesses that have operations, customers, employees, or future plans connected with Florida
Main Point to Consider	Smaller market and sales tax compliance despite low annual costs	Higher annual LLC report fee and Florida-specific tax/sales tax compliance

Which Is Better: South Dakota or Florida?

If you are running a completely online business from outside the United States and do not have a particular reason to operate in Florida, South Dakota's relatively low annual report fee and lack of individual state income tax can make it worth considering.

Florida, on the other hand, has a much larger economy and may make more sense if you plan to establish operations, employees, inventory, or another physical presence there.

For an Amazon seller, simply choosing South Dakota instead of Florida does not automatically remove your tax obligations in other states.

Amazon FBA inventory and other business activities can create tax considerations outside your LLC's formation state.

The better option therefore depends on where and how you actually plan to operate your business, rather than only looking at the state filing fee.

What Documents Should You Keep for Your South Dakota LLC?

Proper record keeping becomes especially important when your business is being operated from outside the United States.

You should generally maintain:

• Articles of Organization

• EIN confirmation

• Operating Agreement

• Registered agent information

• Previous Annual Reports

• Business bank statements

• Amazon sales reports

• Other marketplace sales reports

• Payment processor statements

• Business expense records

• Sales tax permits and returns

• Federal tax returns

• Invoices and receipts

• Payroll records, if applicable

• Business licenses or permits

Keeping these documents digitally organized can make annual compliance and tax preparation much easier.

Common Mistakes Non-Residents Make With South Dakota LLCs

Assuming the LLC Is Completely Tax-Free

South Dakota does not have individual state income tax, but your LLC can still have federal tax and sales tax obligations.

Forgetting the Annual Report

The annual fee may be relatively low, but the report still needs to be filed.

Missing state filings can eventually affect the good standing of your LLC.

Ignoring Sales Tax Nexus

Having no physical office in South Dakota does not automatically mean that an e-commerce business can ignore South Dakota sales tax.

Economic nexus can create obligations for remote sellers.

Using Outdated Sales Tax Information

South Dakota previously used both a $100,000 sales threshold and a 200-transaction threshold for economic nexus.

The transaction threshold has since been removed. This is why relying on old blogs, videos, or tax information can create confusion.

Thinking Amazon Handles Every Tax Requirement

Amazon may collect and remit marketplace sales tax, but that shouldn't be confused with your overall business tax and compliance responsibilities.

Your obligations depend on your complete business activity.

South Dakota LLC for Amazon Sellers

South Dakota can be an interesting state for international Amazon sellers because of its relatively low annual state cost and absence of individual state income tax.

However, your Amazon business should be considered as a complete operation.

You may need to think about:

• Where Amazon stores your inventory

• Sales tax nexus in different states

• Federal tax reporting

• Business banking

• Amazon verification requirements

• LLC annual compliance

• Accurate business records

The state where you form your LLC is only one part of your overall US business setup.

Is South Dakota better than Florida for a non-resident LLC?

It depends on your business. South Dakota has lower annual LLC reporting costs, while Florida has a much larger market and may make more sense for businesses planning to establish operations there. Your actual business activities should determine the choice rather than the state fee alone.

Final Thoughts

South Dakota can be a strong option for non-resident entrepreneurs who want a US LLC with relatively low annual state costs and no individual state income tax.

Its $50 annual report fee can make ongoing state maintenance relatively affordable, while the state does not impose a general franchise tax on LLCs.

However, you should not choose South Dakota simply because it appears inexpensive.

Federal tax reporting, sales tax nexus, Amazon FBA inventory, annual reports, and your business activities in other states can all affect your compliance requirements.

For an Amazon or e-commerce seller, the best state is the one that fits your actual business structure and long-term plans, rather than simply the state with the lowest headline cost.

If you are not sure whether South Dakota is suitable for your business, ReinstaFix can help you review your requirements and set up your US business accordingly.
