Why Does the US Tax Non-Citizens Living Abroad?

Understanding Taxation Across Countries

Every country, to some extent, collects tax from its citizens and legal immigrants. This is a fundamental aspect of maintaining public services and infrastructure. However, the US tax law is unique in how it handles tax responsibilities for individuals living abroad.

Itrsquo;s important to dispel a common misconception: the US is indeed unique in its tax system for non-citizens. Many first-world nations, including some with similar tax policies, collect tax from non-citizens on their property, sales, and income within their jurisdictions.

What Makes US Taxation Special?

The US has a highly specific and extensive approach to taxation that extends to non-citizen residents. Any individual who passes the Substantial Presence Test is deemed a "resident alien" for tax purposes, regardless of their citizenship status or documentation.

This means that non-citizens living in the US for an extended period, even if undocumented, are taxed on their worldwide income. For a given tax year, if an individual accumulates 183 days within the US based on the formula: 1/3 1/6 of the prior two years' presence, they qualify as resident aliens.

This approach implies that there is a deliberate policy in place to ensure tax compliance, recognizing the practical challenges of auditing every individual tax document.

Why Does the US Tax Non-Citizens Living Abroad?

The rationale behind this taxation policy is to manage the infrastructure and resources effectively. By extending tax obligations based on the number of days spent in the country, it addresses the need for a simplified tax collection system.

Spreading Out the Burden of Tax Compliance

By relying on the individual to ensure their taxes are accurately reported, the US reduces the administrative burden on the tax agency. This method has proven to be a workable solution, despite scrutiny and criticism from some quarters.

The benefit of this system is that it maximizes tax revenue while minimizing the need for an expansive tax audit apparatus.

Enforcing Tax Compliance

The system relies on potential penalties for non-compliance, including audits and criminal charges. This enforcement mechanism ensures that individuals adhere to their tax obligations.

A More Inclusive Tax System

Non-resident aliens, on the other hand, are subject to taxes only on their income earned in the US. This distinction highlights a more inclusive approach to benefiting from the tax system.

Many undocumented immigrants who have lived in the US long term are subject to resident alien taxation, as they spend a significant portion of their time in the country. There is a logical reasoning behind this: if someone has integrated into the US community and economy, it makes sense to treat them similarly to documented immigrants for tax purposes.

Conclusion

The US tax system is designed with a specific approach to handle the complexities of international migration. While it may not be the most efficient system, it functions effectively and is well-known globally a testament to its impact on the international community.
