S Corporation vs. C Corporation for Americans Living Abroad

Choosing between S corporation and C corporation tax treatment can change how your business profits are taxed, how you pay yourself, and which returns you need to file. Living abroad adds another layer: where you work, your foreign tax obligations, social security coverage, and the foreign earned income exclusion (FEIE) can all affect the result.

The short answer: An S corporation generally passes income and other tax items through to eligible shareholders. A C corporation generally pays its own federal income tax, and shareholders may also pay tax on dividends. Neither choice automatically minimizes your combined U.S. and foreign taxes. Compare the full picture before forming an entity or making an election.

This guide discusses U.S. federal tax concepts for individual U.S. citizens and resident taxpayers living abroad. It is educational information, not individualized tax, legal or foreign-country advice. Corporate classification, payroll, ownership and local-country issues may require an appropriately qualified specialist.

S corporation vs. C corporation: the basic differences

For the IRS descriptions, see S corporations, corporations, and paying yourself.

An LLC is a legal entity; S and C describe federal tax treatment

An LLC is formed under state law. An eligible LLC may be taxed in different ways under federal rules, including by making a corporate or S corporation election if it qualifies. A single-member LLC is generally disregarded for federal income tax unless it elects corporate treatment; a domestic LLC with at least two members is generally treated as a partnership unless it elects otherwise. State and foreign-country treatment may differ. See the IRS LLC classification guidance.

Don't compare “LLC” and “corporation” as though each always has one tax result. First establish the legal entity, its current tax classification and any election already in force.

Can an American living abroad own an S corporation?

Living abroad does not by itself disqualify a U.S. citizen or resident from being an S corporation shareholder. But the company must meet all eligibility rules. In general, an S corporation must be domestic, have no more than 100 shareholders, have only allowable shareholders and have only one class of stock. A nonresident alien individual generally cannot be a direct shareholder; there are specific rules for permitted trusts and other owners. Citizenship and U.S. tax residency, not a foreign address alone, matter here. See IRS S corporation eligibility.

This matters if you plan to add a non-U.S. business partner or transfer shares to a spouse or trust. Review the proposed owner and the transfer before it happens: an ineligible shareholder can terminate an S election. A C corporation is not subject to that particular S corporation restriction, but foreign ownership can create other reporting and tax requirements. Do not assume a C corporation eliminates foreign-owner reporting.

How wages, dividends and the FEIE fit together

The FEIE is a personal income-tax exclusion, not a blanket exemption for a business. To use it, an individual must have qualifying foreign earned income, a foreign tax home and meet the bona fide residence test or physical presence test. Limits and election rules also apply.

For wages and other compensation for services, the source generally follows where the work is performed, not where the employer or bank account is located. Wages for qualifying services performed abroad may be eligible for the FEIE if the other requirements are met; workdays in the United States can affect the allocation. A U.S. employer or U.S. corporation does not, by itself, prevent foreign-source wages. See IRS foreign earned income guidance.

Dividends are investment income and do not qualify as foreign earned income. Do not assume that an S corporation's pass-through income or a cash distribution is interchangeable with wages or automatically qualifies for the FEIE. Corporate income, wage payments and distributions are different tax concepts; the facts and applicable rules must be analyzed separately.

The FEIE generally addresses federal income tax, not payroll taxes. It also interacts with the foreign tax credit: foreign taxes attributable to excluded income generally cannot also be used to claim a U.S. foreign tax credit. A calculation should consider wage allocation, foreign taxes, credits, other income and longer-term circumstances before an election is made. See IRS guidance on the foreign tax credit and excluded income.

Payroll and social security: don't stop at the income tax calculation

An S corporation shareholder who works for the business generally must receive reasonable compensation for services before non-wage distributions. Calling payment a distribution does not automatically make it one for employment-tax purposes; the IRS can reclassify compensation. The amount depends on the work, the business and comparable pay, not a universal percentage. See IRS guidance on S corporation compensation.

For either type of corporation, determine whether U.S. employment taxes apply to the wages and whether the country where you work has its own payroll and social security requirements. A U.S. totalization agreement, where applicable, can assign social security coverage to one country; the applicable agreement and a certificate of coverage matter. Do not assume you can choose the system or that the FEIE settles payroll obligations.

For example, suppose a U.S. citizen living abroad owns a profitable consulting company and performs the client work personally. An S corporation may allocate its taxable items to the owner, while reasonable compensation is treated as wages. A C corporation generally pays corporate tax and may later distribute a dividend. Whether either arrangement is better depends on the actual compensation, payroll coverage, profit retention, foreign tax treatment, eligible credits and compliance costs. A comparison based only on the U.S. income-tax rate would leave out material costs.

The country where you live may treat the business differently

A U.S. S election is a U.S. federal tax classification. Do not assume your country of residence will treat the company as a pass-through or tax the owner and company in the same year or in the same way as the United States. A mismatch can affect double taxation and the practical availability or timing of a foreign tax credit.

Before acting, ask a qualified adviser in your country of residence about company residence, management and control, local business registration, payroll, owner compensation, dividends and local reporting. Consider a U.S. international tax specialist where entity classification, treaty positions or foreign tax credit issues are complex. FileAbroad focuses on U.S. individual tax preparation and international reporting; it does not provide foreign-country legal or tax representation.

Returns and ongoing costs to compare

The corporation's annual return is only part of the cost. Depending on the facts, a comparison may need to include:

1. Corporate return and records: Form 1120-S and K-1s for an S corporation, or Form 1120 for a C corporation, along with reliable books and records.
2. Payroll and employment filings: Wage reporting, withholding, and payroll tax filings where required, plus professional payroll support.
3. Individual return: Wages, applicable S corporation items or C corporation dividends, FEIE or foreign tax credit calculations, and any related schedules.
4. State and local requirements: Formation and annual-report fees, state income or franchise taxes, and possible filing where you or the business maintain connections.
5. Foreign obligations: Local company, payroll, tax and social security advice and compliance, as applicable.
6. Foreign accounts: A business account can raise separate reporting questions for U.S. persons with a financial interest or signature authority. Review the facts under the FBAR rules; do not assume a company account is automatically excluded.

When do you make an S election?

An eligible entity generally makes an S election on Form 2553, with shareholder consent. The general deadline is no more than two months and 15 days after the start of the tax year for which the election is to take effect, or any time in the preceding tax year. The precise deadline depends on the entity's tax year and circumstances. Relief for a late election may be available if its requirements are satisfied; it is not automatic. See the Form 2553 instructions.

Don't file an election based only on a headline tax saving. Confirm eligibility, effective date, payroll, expected ownership changes and foreign-country treatment first. Changing an existing corporation's status can also carry consequences requiring specialist review.

Questions to gather before comparing structures

• What is the business's legal entity, state of formation and current federal classification? Have any elections been filed or accepted?
• Who owns it now, and might a nonresident alien spouse, partner, investor, trust or entity become an owner?
• Where will each owner physically perform services, and what compensation is reasonable for that work?
• What profit will the company earn, retain and distribute? What payroll, accounting and annual filing costs are expected?
• How does your country of residence treat the company and your compensation, and which social security system covers the work?
• Are FEIE, foreign tax credits, state filings or prior-year returns already involved?

Get a clear next step

If you already own a business and are unsure how it affects your U.S. individual return, tell Chip about your situation. Include the country where you live, the entity's current classification, ownership and the years involved—without sending sensitive tax documents through the public inquiry form. FileAbroad will review fit and explain the next step. Corporate structuring, foreign-country advice and other matters outside the accepted scope may need a qualified specialist or referral.
