What is the best US business entity for me in 2026?

Keep in mind, though, that company law in the USA is a matter for the individual states. The rules overlap by about 90%, but some things are handled differently from state to state.

Insolvency law is a good example. The basics are the same in every state, but New York has different deadlines, procedures and options than, say, California. We go into this in more detail later.

1What is a C Corporation?

A C Corporation is a stock corporation, and its structure and workings are quite comparable to the public limited companies familiar across Europe.

The C Corp has the following governing bodies:

• President (the senior officer running the business)
• CEO (chief executive officer)
• Treasurer (in charge of finances)
• Secretary (keeps the corporate records)

One person can hold several or all of the roles in a company. Unless otherwise specified, every officeholder counts as a managing officer.

The C Corp pays federal corporate income tax in the USA (21%). On top of that comes any corporate tax levied at state level.

Dividends are then taxed again as investment income, always where the shareholder lives. The US levies a withholding tax on distributions, which is generally credited against the tax on dividends in your home country.

The corporate tax return for the previous year is due by April 15. An extension to October 15 is easy to get. Apart from the corporate tax return (with at least 25% foreign ownership, plus Form 5472 if there were reportable transactions with related parties), nothing has to be filed with the authorities. Extensive annual financial statements like those in Europe do not exist in the USA. No balance sheets or similar documents are filed with the state registry; all that is required is an annual status report.

A C Corp has share capital divided into shares. All corporations in the USA issue bearer share certificates by default, unless agreed otherwise. In electronic stock trading this would of course be impractical, so there the shareholders agree to electronic share administration.

The share capital can be set at any amount and does not have to be paid in.

As with other stock corporations, different classes of shares can be issued. A C Corp can also have an unlimited number of shareholders, while an LLC is limited to "only" 1000.

Shares in a C Corp can be traded on the stock exchange; interests in an LLC cannot.

2What is an LLC?

An LLC is a relatively young entity type that has only existed since the 1970s. It is now available in every US state. For tax purposes the LLC is a partnership in most cases, but under company and liability law it is a limited liability company.

The LLC has no mandatory governing bodies, but it can optionally appoint a manager to run the company's business. Otherwise, management lies with the members.

An LLC has no legally required share capital. How each member holds an interest in the LLC and how profits are shared among them is purely a matter of private agreement.

The members can draw up an agreement among themselves. This "Operating Agreement" is required by law in California, New York, Missouri, Maine and Delaware and is optional for LLCs in other states. The Operating Agreement is never made public.

Membership certificates can be issued if you wish. They are not stock certificates, though; they simply confirm the member's contribution.

The LLC is by far the most popular entity type and has now left the C Corp far behind in the number of companies formed.

The LLC can choose whether to be classified for tax purposes as a partnership or as a corporation. 99% of all LLCs choose partnership treatment. The LLC then pays no tax itself; the tax is paid by the members. The LLC still has to file a separate tax return (Partnership Tax Return).

If you are a foreigner and a member of an LLC, you must file a US income tax return (covering only your US income) if the LLC has a US permanent establishment. You are then assessed like a US taxpayer. Expect a tax burden of typically 25% to 35%, plus state tax.

The LLC must withhold 37% tax on distributions (30% for single-member LLCs). Members get back any overpaid tax after filing their income tax return.

Whether the LLC's profits are then taxed again in your country of residence depends on your specific situation and where you live. How your home country treats an active trading LLC matters a great deal: if your tax authority classifies the LLC as a corporation, it can get expensive. More on this below.

2.1Single-member LLC (disregarded entity)

An LLC with just one member ("single-member LLC") is a so-called "disregarded entity": it is registered for tax purposes but does not file its own tax return. It is treated like a sole proprietorship, and income and expenses are reported on the owner's personal tax return.

Single-member LLCs also have certain reporting requirements involving some forms the company must file with the IRS.

The state registry usually lists just one natural person as the contact for the LLC. This can be a member, a manager or anyone else connected with the LLC.

Want a US LLC that stays tax-free in the US? Then our sister site zerotax.llc is the right place. It covers the LLC for owners who live outside the US and whose business does not take place in the US: no permanent establishment, no US tax on the profit. This site covers the opposite: companies that genuinely operate in the US, have a permanent establishment there and pay taxes in the US. Both are run by the same firm in Austin, Mount Bonnell Advisors.

2.2How the LLC becomes a tax trap

Comparing an LLC and a Corporation side by side, it quickly becomes clear that an LLC, as a pass-through entity, has clear tax advantages, especially when no further taxes are due in your country of residence.

But there's a risk of counting your chickens before they hatch:

The LLC becomes a tax trap if the tax authorities in your country of residence do not recognize it as a partnership.

An LLC makes sense, for example, for clients who live in the USA or are moving there soon and do not expect any profits in the company until then.

3What is a Limited Partnership (LP)?

Find out more about our US Limited Partnership (LP) service packages

Because the US LP matches the limited partnership as a legal form, tax authorities at home can classify it easily, and the LP is reliably treated as a partnership in your home country.

An LP has a "General Partner", the partner with unlimited liability. This is usually an LLC or a corporation. The General Partner manages the LP.

There are also 1 to n "Limited Partners". Their liability is limited to their contribution, and they are not involved in managing the company unless they are given authority to act for it.

The partnership is tax-transparent: tax is assessed at the level of the partners. The US tax burden is around 25% to 35%, depending on the size of the profit and the industry. Every partner has to file a US tax return.

Usually no further taxes are due in your country of residence, although this depends largely on the tax treaty.

The LP has to withhold 37% tax on distributions. Partners get back any overpaid tax when they file their US tax return.

4Which is better: C Corporation, LLC or Limited Partnership?

My view: the C Corporation is the safest and simplest structure for most clients. The C Corporation is always a reliable choice, long established and familiar to every tax authority. Even if the tax burden looks higher than with other US structures at first glance, most entrepreneurs don't expect big profits in their first two years in the US market anyway, so tax is a secondary question, at least at the start. What matters is getting going, and you should be prepared to fine-tune the structure again in two to three years.

When it comes to reputation in day-to-day business, the legal form makes little difference.

A corporation in America carries nowhere near the prestige of a public limited company in Europe. Nobody here freezes in awe when a company name ends in "Inc."

In terms of liability, the LLC is on a par with the C Corporation. Plenty of court rulings confirm this.

The single-member LLC is a special case here. In theory it offers liability protection too, but a number of court rulings have set aside that protection for single-member LLCs in individual cases. Those cases, however, involved deliberate harm to customers and suppliers.

Some states have since written liability protection for these LLCs into their company law.

In an LP, the general partner (the one with unlimited liability) is usually a company without assets, so the liability risk stays limited here too.

In the end, the choice of the best structure should rest on personal and strategic considerations. Above all, though, keep the possible tax implications in mind, especially when foreign shareholders are involved.

The following list can help you decide: 

• I live in the USA, in a non-dom country or in a country without CFC rules: LLC

• I plan to move to the USA or a non-dom country soon: LLC

• I plan an IPO in the future: C Corp

• I'd rather play it safe: C Corp

• My partners and I prefer the C Corp because we know the public limited company well and find the LLC hard to assess: C Corp

• My investors have a preference: often C Corp

A small but interesting side note: IRS statistics show that a C Corporation is far less likely to be audited than an LLC. The IRS assumes that C Corporations tend to be "large" companies that follow the rules closely and employ accountants to make sure the tax return is 100% correct. Statistically, auditors recover far more from an LLC than from a C Corporation.

If all these questions are answered and there is still no clear favorite, in most cases I would recommend the C Corporation (assuming you don't live in the USA).

5.3Scenario 2: The sole shareholder is German and lives in Malta with non-dom status

• We assume the company has one shareholder who lives in Malta and is non-dom there.

• We assume all profits are distributed to the shareholder, but paid into a non-Maltese account, so they are tax-free in Malta.

• The calculation includes all taxes due in the USA and Malta. 

• We assume the corporation is held by a UK holding company. This reduces US withholding tax to 5%, which is included in the calculation. No further tax is due in the UK.

• Malta has no "Totalization Agreement" with the USA. As a result, income from US partnerships is not subject to "Self Employment Tax" (social security contributions) when the shareholder lives in Malta.
