How to Avoid Double Taxation: Strategies for Individuals and Businesses

Nobody wants to pay tax on the same dollar twice. Yet every year, business owners and expats run into this exact problem. A corporation pays tax on its profits. Then shareholders pay tax again on the dividends from those same profits. An American working in another country can face tax bills from two governments on the same paycheck.

This is double taxation, and it costs people real money. The good news is that the tax code offers legal ways around it. This guide walks through what double taxation is, where it shows up, and the specific steps you can take to reduce or avoid it.

What Does Double Taxation Mean?

Double taxation happens when the same income gets taxed twice. It can happen at two levels of government, in two countries, or even within one business structure. There are two broad categories:

• Corporate double taxation, where a company pays tax on its profits, then owners pay tax again when they receive those profits as dividends.
• International double taxation, where a person or business earns income in one country and gets taxed there, then gets taxed again by their home country on the same income.

A third version shows up less often but still matters. Multi-state double taxation can hit remote workers or business owners who earn income in one state but live in another.

How Double Taxation Works

The mechanics differ depending on where the double tax hits. In a corporation, the company itself is treated as a separate taxpayer. It files its own return and pays its own tax bill.

When the company distributes profits to shareholders as dividends, the IRS treats that dividend as new income. The shareholder reports it and pays tax again, even though the company already paid tax on those earnings.

International double taxation works differently. The United States taxes citizens and green card holders on their worldwide income, no matter where they live. If you’re working in London or Tokyo, your host country likely taxes your local income too. Without relief, you’d owe tax to both governments on the same paycheck.

Types of Double Taxation: Corporate vs. International vs. Multi-State

Each type has its own triggers and its own fix.

• Corporate double taxation applies mainly to C corporations. It does not apply to sole proprietorships, partnerships, LLCs, or S corporations, which pass income directly to owners.
• International double taxation applies to US citizens, green card holders, and businesses earning income abroad.
• Multi-state double taxation applies when your work income and your residency don’t line up in the same state, though most states offer a credit for taxes paid elsewhere.

International Double Taxation

This is the version most expats and remote workers run into. The United States is one of the only countries that taxes based on citizenship, not just residency. That means an American living in Barcelona still files a US return, even if they never set foot in the country all year.

Most countries tax based on residency instead. So if you live and work in Barcelona, Spain taxes your income there too. Without a treaty or an exclusion, you’d pay tax twice on the same earnings.

The US has built two major tools to fix this: the Foreign Earned Income Exclusion and the Foreign Tax Credit. We’ll cover both in detail below.

Double Taxation Examples

Seeing real numbers makes this easier to understand.

Example 1: Corporate Double Taxation

A small manufacturing company earns $500,000 in profit. At the 21 percent federal corporate rate, it owes $105,000 in corporate tax. That leaves $395,000.

The owners decide to pay themselves $200,000 in dividends from what’s left. Depending on their tax bracket, they could owe another 15 to 20 percent in personal tax on that dividend income. The same $200,000 gets taxed once at the corporate level and again at the personal level.

Example 2: International Double Taxation

An engineer moves to Singapore for a two year contract. She earns $140,000 a year. Singapore taxes her local income under its own system. The US also requires her to report that same $140,000 on her federal return, since she remains a US citizen.

Without the Foreign Earned Income Exclusion, she could owe tax in both countries on the same salary.

Example 3: Investment Income From a Foreign Source

A retiree holds foreign stock that pays dividends. The foreign country withholds 15 percent tax at the source. The IRS also treats that dividend as taxable US income. Without a credit, that dividend gets taxed twice before it even reaches a bank account.

Client Story

Business Entities and Double Taxation

Not every business structure faces this problem. It mostly comes down to how the IRS classifies your entity.

First Tier: 21 Percent Corporate Tax (Form 1120)

C corporations file Form 1120 and pay a flat 21 percent federal tax on profits. This is the first layer of tax. State corporate taxes may add another layer on top, depending on where the business operates.

Second Tier: Dividends Taxed at the Personal Level

When the corporation distributes profits, shareholders report that income on their personal returns. Qualified dividends are taxed at capital gains rates, generally 0, 15, or 20 percent depending on income. This is the second layer.

Exclusions: Pass-Through Entities

Sole proprietorships, partnerships, LLCs, and S corporations don’t pay corporate tax. Profits pass directly to the owners’ personal returns instead. This avoids the first layer of tax entirely, which is why many small business owners choose these structures.

Debate on Fairness: Is Double Taxation Legal?

Yes, double taxation is completely legal. Congress designed the corporate tax system this way on purpose, treating corporations as separate legal entities from their owners.

Critics argue it discourages investment and pushes business owners toward debt financing instead of equity, since interest payments are deductible but dividends are not. Supporters argue it reflects the real legal separation between a company and its shareholders, and that corporations benefit from limited liability protections in exchange.

Congress has adjusted the system over time. The Tax Cuts and Jobs Act of 2017 lowered the corporate rate from 35 percent to 21 percent, partly to ease this burden. Lawmakers continue to debate further changes.

How to Avoid Double Taxation as an Expat or a Business

Here’s where strategy matters. You have legal, well established tools available, whether you run a business or live abroad.

• Choose a pass-through business structure when it fits your situation.
• Claim the Foreign Earned Income Exclusion if you qualify.
• Use the Foreign Tax Credit for income that doesn’t qualify for exclusion.
• Rely on tax treaties between the US and your host country.
• Pay yourself a reasonable salary instead of relying only on dividends.

1. Leverage Tax Treaties

The United States has income tax treaties with more than 60 countries. These agreements determine which country gets the first right to tax specific income types, and they often reduce or eliminate withholding tax on dividends, interest, and pensions.

What Is a Double Taxation Agreement?

A double taxation agreement, or tax treaty, is a formal deal between two countries. It sets rules for which country taxes which type of income, and it often includes a tie breaker for people who could be considered a resident of both countries at once.

2. Use the Foreign Earned Income Exclusion (FEIE)

For the 2025 tax year, the IRS allows qualifying individuals to exclude up to $130,000 of foreign earned income. For 2026, that limit rises to $132,900 per person.

To qualify, you generally need to meet one of two tests:

• The Physical Presence Test, which requires 330 full days in a foreign country during a 12 month period.
• The Bona Fide Residence Test, which requires an uninterrupted full tax year of residency abroad.

The FEIE only applies to earned income, like wages or self employment income. It does not cover dividends, interest, rental income, or pensions.

3. Rely on the Foreign Tax Credit

The Foreign Tax Credit lets you offset US tax with income tax you already paid to a foreign government. Unlike the FEIE, it can apply to passive income like dividends and interest, not just wages.

You claim this credit using Form 1116. You cannot use the credit and the exclusion on the exact same dollar of income, but many taxpayers combine both strategically. The FEIE covers earned income up to the limit, while the credit offsets tax on income above that limit or from passive sources.

4. Opt for a Pass-Through Entity

If you’re starting a business, consider an LLC or an S corporation instead of a default C corporation. Profits flow straight to your personal return, so you skip the corporate level tax entirely.

An S corporation has limits though. It caps ownership at 100 shareholders, and all shareholders must be US citizens or residents.

5. Pay Salaries Instead of Dividends

If you already run a C corporation, consider paying yourself and other owner employees a reasonable salary. Salaries are a deductible business expense, which reduces the company’s taxable profit. Dividends are not deductible.

The IRS does require that the salary be reasonable for the work performed. Paying yourself an unusually low salary just to dodge payroll tax can trigger an audit.

Forms for Avoiding US Double Taxation: Checklist

Keep this list handy when you file:

• Form 2555, Foreign Earned Income, to claim the FEIE.
• Form 1116, Foreign Tax Credit, for tax paid to another country.
• Form 1120, US Corporation Income Tax Return, for C corporations.
• Form 1120S, for S corporations electing pass-through status.
• Form 2553, to elect S corporation status.
• Schedule B, for reporting foreign accounts and trusts if required.

Multi-State Double Taxation for Remote Workers

This version gets less attention but affects a growing number of people. If you live in one state and earn income in another, both states might try to tax the same paycheck.

Most states solve this with a resident tax credit, which reduces your home state tax by what you already paid elsewhere. A handful of states, including New York, apply a “convenience of the employer” rule that can still create double tax exposure for remote workers. If your employer is based in Manhattan but you work remotely from Los Angeles, check your state’s specific rules before assuming you’re covered.

Choosing the Right Structure for Your Situation

There’s no single answer that fits every business or every expat. A freelance consultant working from a home office near the Getty Center in Los Angeles has different needs than a manufacturing company with a factory floor.

Before you decide, ask yourself:

• Will your business generate profits you plan to reinvest, or do you need regular distributions?
• Do you have foreign partners or investors, which could disqualify you from S corporation status?
• Are you living abroad long term, or on a short assignment that might not meet the physical presence test?
• Does your host country have a tax treaty with the United States?

A local CPA who understands both federal rules and your state’s specific tax code can help you map out the right structure. If you’re in the Los Angeles area, a local CPA in Granada Hills or a firm serving the San Fernando Valley can provide guidance on these complex issues, helping small business owners and expats navigate both federal and California tax requirements with confidence.
