Types of Business Structures: The Real Trade-offs Behind Each One

Five major structures cover real-world situations: sole proprietorship, partnership, LLC, S-Corp, and C-Corp. The right structure depends on three factors: whether you want to protect your personal assets, whether outside funding is a goal, and whether you have an SSN. Once you answer these three, the right choice usually follows.

Three Questions Before You File

For now, let’s skip definitions. Three questions do the work before a state filing portal opens.

1. Will this business ever be sued, sign contracts, or hold debt in its own name? If any of those answer yes, then you can cross off sole proprietorships and general partnerships. Neither structure provides legal separation between the owner and the business.
2. Is a venture capital raise a possible goal in the next two to three years? If this is the case, a C-Corp will most likely be formed in Delaware. If this is not applicable, then an LLC covers most situations.
3. Does every stakeholder of the business hold an SSN and a legal status in the US? Only then is an S-Corp an applicable choice. If this isn’t satisfied, then it is an unavailable choice, no matter how appealing the numbers may look.

Sole Proprietorship: The One Nobody Files For

There’s no paperwork required when you become a citizen and start selling. By default, a sole proprietorship is formed. There is no need to file anything to establish the business. There is no need for a separate entity or an EIN unless you hire someone who needs to be on the payroll.

There is, however, no separation of personal and business liabilities. A lawsuit filed against your business means all of your personal assets become subject to seizure. Dissatisfied freelance clients can file a lawsuit against you and seize your personal funds.

This structure is not available to founders who do not have citizenship or a long-term stay in the US. No US banks will agree to this structure without an SSN.

Essentially, this is a structure formed to test an idea over a weekend.

General Partnership: Same Exposure, Now Shared

There is no need to form an LLC or corporation if two or more people want to go into business together. General partnerships do not offer liability protection like corporations do. Anything a partner agrees to on behalf of the business becomes the other partner’s liability.

Each partner can sign contracts and agreements to bind the business to obligations. Each partner, however, is financially responsible for the other partner’s actions. Leasing a business space, for example, puts both partners under financial obligation regardless of the partnership agreement or ability to pay.

An LLC with an operating agreement costs a few hundred dollars to file. You think that’s a waste when your idea is first forming. That changes when the first partnership dispute happens, and you realize you should have paid for that agreement.

If you choose to skip an agreement, your partnership runs on trust. Trust isn’t a legally binding document.

LLC: The Workhorse Structure for International Founders

LLCs solve the two issues mentioned: personal liability and the avoidance of corporate formalities. Personal liability has advantages and disadvantages, as LLCs have the benefit of pass-through taxation. Profits avoid double taxation at the corporate and personal levels.

Filing costs by state (as of early 2026)

Wyoming	$100	$60 minimum annual report
Delaware	$90–$110	$300 flat annual franchise tax, due June 1
New Mexico	~$50	No annual report requirement

Wyoming and Delaware dominate for good reason: neither requires US residency or a Social Security number to form a company. Of the two, Wyoming is more cost-efficient for founders without near-term funding. Delaware’s expenditure exceeds Wyoming’s when a US-based VC becomes involved. Delaware’s Court of Chancery has decades of business case law that investors trust and attracts the default of legal forms from US VCs.

Processing time for standard Wyoming filings is 10-14 business days. By paying for expedited service, you can reduce delivery time to 1 or 2 days. Delaware’s filing times follow a similar trend but lengthen during tax season.

The bottleneck nobody plans for

Reality check: Most of the problems that slow down the formation of a US business occur during the EIN application process, and not during the state filing.

Often, it is the EIN application, not the entity, that causes delays for founders who do not have an SSN or ITIN, which means they can’t use the IRS’s online EIN application. These founders must instead fill out the SS-4 form, which is currently taking 4 to 6 weeks to process. For those looking to launch their business on a specific date, the EIN application must be completed first, and the LLC formation can be done in parallel.

S-Corp: A Tax Election, Not an Entity

S-Corps are another sore area of confusion for most. An S-Corp is not an entity at all; it is a tax election filed with the IRS after forming an LLC or corporation. Once an LLC has its S-Corp election filed, income can be distributed to the members as “reasonable salaries,” which are taxed as regular wages, and as distributions, which are taxed at a lower rate.

The gotcha: almost every S-Corp owner has to be a U.S. citizen or resident. Non-resident citizens will be disqualified. Unless you have U.S. resident owners, this section need not be addressed, as there is no point in pursuing an ineligible election.

C-Corp: What Investors Actually Expect to See

A C-Corp is a separate tax entity and therefore is taxed at the 21% corporate rate. The shareholders are taxed on the dividends they receive. Thus, the dreaded double taxation, as it is often called, is the main reason why founders avoid a C-Corp.

A founder may choose a C-Corp to raise venture capital. Almost all of the institutional investments are focused on Delaware C-Corps. If you are planning to raise a priced round, take a SAFE backed by a US fund, or do an IPO in the future, you will almost certainly need to be a C-Corp. Most VC-focused founders change their legal entity from an LLC to a C-Corp, often before institutional investment, and not when they first consider raising funds.

Forming a Delaware C-Corp is similar in cost to forming an LLC, at around $89 to $109, depending on the number of shares. It also has a minimum $300 franchise tax, calculated at a higher rate under Delaware’s alternate method for larger authorized share counts. The formation of a C-Corp also entails a greater time commitment, including annual and board meetings.

Verdict: No realistic VC raise on the horizon means the C-Corp’s double taxation and paperwork load usually aren’t worth taking on yet.

Where This Goes Wrong in Practice

Rarely is the challenge in designing paperwork. The following five decisions nonetheless end up costing founders both time and money.

Copying a friend’s structure. Different founders have different funding structures, tax residences, and business models. The structure of a successful SaaS company is unlikely to work for an e-commerce company with a different risk profile.

Defaulting to Delaware. Delaware charges a reasonable cost only if there is venture funding. A bootstrapped agency or store that is not funded by institutions pays a real premium to a state in which the primary advantage does not yet apply.

Filing the entity is the first step. An LLC usually takes a few days to form. An EIN for a non-resident founder can often take weeks. Founders who file an LLC and then think about banking often lose six weeks that they haven’t accounted for.

Assuming you are eligible to file for an S-Corp. Non-resident founders who request the S-Corp election do so out of habit, based on US-centric advice that doesn’t even state the citizenship requirement.

Ignoring the annual reporting. Administrative dissolution can be avoided by filing all required reports and paying all required taxes on time. The time and cost to reinstate a dissolved entity are always greater than the cost of filing the required reports and paying taxes on time.

FAQs

What is the least expensive structure to form? Sole proprietorships or general partnerships are free to file, but have no liability protection. Among structures that offer liability protection, an LLC in New Mexico or Wyoming is typically the least expensive to form and maintain.

Can someone who isn’t a U.S. citizen form an LLC? It is possible. In states like Wyoming, Delaware, and New Mexico, you can form an LLC without providing your citizenship or Social Security number. You will, however, need an EIN and a registered agent with a physical address in that particular state.

Do I need a lawyer to choose a structure? Usually not for a simple LLC or C-Corp formation. However, some people find it worthwhile to pay for the service for S-Corp formation, determining how to structure a multi-owner equity split, and drafting the terms prior to a funding round.

How long does it take to convert from an LLC to a C-Corp? A Delaware statutory conversion generally takes a couple of weeks after filing; however, the tax implications of a conversion will be different from starting a C-Corp from scratch. Most founders with a clear VC timeframe find it easier to form a C-Corp initially rather than convert later.

Conclusion 

When you form your LLC, you are making a bet about the behavior of your business. Things like who is liable, who is investing, and who will fill out the tax return will all be impacted by your choice of an LLC.

If you guess right about your business behavior, the following years of compliance will be easy. If you guess wrong about your business behavior, rectifying that choice will be more expensive than any filing fee you’ve ever had to pay.
