The Exclusive Citizenship Tax Act Debate: Why Making U.S. Citizens Choose Doesn’t Make Tax Sense

America has long branded itself the land of the free, yet in the world of tax policy it holds a distinctive, and often controversial position. The United States is one of only two countries in the world that taxes its citizens on worldwide income regardless of where they live, the other being Eritrea.

Recent policy discussions labeled as the “Exclusive Citizenship Act” propose to make dual-U.S. citizens renounce their foreign citizenship or their U.S. citizenship. Those who do not comply would automatically lose their U.S. citizenship one year after the bill becomes law.

Critics argue the policy makes little economic or social sense, leads to unnecessary tax compliance burdens, and could encourage more U.S. citizens living abroad to renounce their citizenship, ultimately harming U.S. economic interests and international goodwill.

This article explains how the U.S. taxation system treats citizens abroad, why this approach is unusual globally, how U.S. expats currently minimize or avoid taxes, what happens when they renounce citizenship, the economic and tourism impacts, and why reform advocates say the system needs to change.

Why U.S. Taxation for Citizens Abroad Is Unusual

Most developed countries use residence-based taxation, meaning income tax obligations depend on where you reside, not citizenship. In contrast, the U.S. uses citizenship-based taxation (CBT)—meaning U.S. citizens must report and pay federal income tax on worldwide income no matter where they live.

Under U.S. law, even U.S. citizens earning income overseas must annually file a U.S. tax return and report worldwide income. However, a large proportion of U.S. citizens abroad legitimately pay no tax due to exclusions, credits, and treaties. According to IRS data, a significant share of expatriate tax filers owe zero federal income tax after applying these provisions.

How U.S. Citizens Abroad Can Reduce or Avoid Tax Liability

Although U.S. citizenship triggers worldwide taxation, the U.S. tax code provides tools that often eliminate or greatly reduce U.S. tax liability for Americans living overseas:

• Foreign Earned Income Exclusion (FEIE)

Under Internal Revenue Code §911, qualifying U.S. citizens abroad can exclude a large amount of foreign earned income from U.S. taxable income ($130,000 for 2025, indexed annually).

• Foreign Tax Credit (FTC)

U.S. taxpayers can claim a credit for income taxes paid to another country, reducing U.S. tax owed to prevent double taxation. Canada has more compressed tax brackets and significantly higher provincial tax rates often creating foreign tax credits in excess of what is needed to offset all U.S. tax.

• Tax Treaties

The U.S. has income tax treaties with many countries that allocate taxing rights and mitigate double tax burdens.

• Standard Deduction Thresholds

Even without foreign income exclusions, many expatriates earn below the U.S. standard deduction threshold and thus owe no tax.

These provisions allow many U.S. citizens abroad to file U.S. tax returns with no federal income tax due, especially when they live in moderate cost-of-living countries and earn moderate incomes.

The Problem With Citizenship-Based Taxation

Critics label U.S. CBT as obsolete, arguing it:

• Creates compliance complexity and cost for citizens abroad
• Leads to banking and financial barriers internationally due to FATCA reporting requirements, since foreign financial institutions may treat U.S. expats as compliance burdens under the Foreign Account Tax Compliance Act (FATCA).

Only Eritrea maintains a similar citizenship tax, and even it is much harsher there; the U.S. system has widely acknowledged exemptions and foreign tax relief provisions that Eritrea does not provide.

Renunciation of U.S. Citizenship: Tax and Estate Consequence

As global mobility rises, citizenship renunciation has increased among U.S. expatriates—sometimes not for ideological reasons but for practical tax, financial, or compliance ones.

• Covered Expatriates and Expatriation Tax

Individuals who renounce U.S. citizenship may be treated as covered expatriates and subject to the U.S. exit tax regime under IRC §§877 and 877A. This can include a mark-to-market tax on unrealized gains on worldwide assets at the time of expatriation, and other compliance tests if the IRS determines tax avoidance as a principal purpose of renouncing.

• Estate and Gift Tax Consequences

Covered expatriates’ gifts and bequests to U.S. persons may face special tax treatment under U.S. law, often taxed at the highest estate or gift tax rates.

• Restrictions for Former Citizens

The Reed Amendment was passed to bar admission of former citizens who renounced to avoid taxes, though it has never been fully enforced due to procedural issues.

• Loss of Estate Tax Exemption

U.S. citizens enjoy a high basic estate and gift tax exclusion ($15 million per person in 2026). Non-citizens, by contrast, qualify for only a small exclusion amount of $60,000 on U.S. situs assets, making estate planning significantly more expensive for former citizens.

For some expatriates, renunciation may lead to selling U.S. property because estate tax consequences make holding U.S. assets less attractive.

The Economic and Tourism Impact of Citizenship Policy and Broader Political Trends

U.S. tax policy on citizens abroad intersects with broader political narratives and economic effects, especially in tourism.

Declines in U.S. Inbound Tourism

International travel to the United States has shown signs of weakness in 2025, with inbound visitor spending projected to fall to around $169 billion, down from $181 billion in 2024. Analysts link some of this softness to global political perceptions and visa policy changes.

Tourism forecast data indicates that international arrivals are below pre-pandemic levels, and foreign tourism is projected to decline, losing billions in visitor spending overall.

Canada–U.S. Tourism Shift

Canadian travel to the U.S. also declined in recent periods due to economic and political tensions, with outbound Canadian trips down and spending in the U.S. decreasing year-over-year.

Additional surveys and analyses reported Canadians canceling or modifying travel plans to the U.S. in response to policy tensions, leading to notable economic impacts for U.S. border communities.

Bottom Line

The United States’ citizenship-based taxation system remains an outlier globally. Although many U.S. citizens abroad legally pay no U.S. tax thanks to credits and exclusions, others do pay taxes in the U.S. because of mismatches in foreign tax credits, alternative minimum tax, Passive Foreign Investment Companies (PFICs), Controlled Foreign Corporations (CFCs), net investment income tax, and the Medicare surtax.

As tourism patterns shift and some expatriates choose renunciation because they are forced to, for economic clarity, or freedom from complex compliance, a loss of taxpayers inevitably leads to a reduction in tax revenue. The Exclusive Citizenship Act could cause our tax base to decrease and create more international tensions, further reducing U.S. tourism and immigration. This bill would negatively affect our national deficit, putting more pressure on future U.S. taxpayers (our children) and creating headwinds for future economic and market growth.
