Can Spouses Be Residents of Different States for Tax Purposes?

Spouses living in different states may wonder how their residency status affects their taxes. Whether due to work, family obligations, or personal preferences, couples sometimes maintain separate residences across state lines, creating unique tax challenges that require careful consideration.

Understanding the tax implications and filing options is essential for avoiding unexpected liabilities or compliance issues.

State Residency Rules

Each state has its own criteria for determining residency, which can significantly impact individuals who split their time between multiple locations. Some states use a “domicile” test, considering where a person has their permanent home and intends to return. Others apply a “statutory residency” test based on the number of days spent in the state. For example, New York considers someone a resident if they maintain a permanent place of abode and spend at least 183 days there.

Beyond physical presence, states may consider voter registration, driver’s license issuance, vehicle registration, and financial account locations. California, for instance, evaluates where an individual has the closest social and business ties, including employment, property ownership, and professional relationships.

For spouses living in different states, residency determinations can become even more complex. Some states assume a married couple shares the same residency, while others allow each spouse to establish residency independently. Community property states, such as Texas and Arizona, require income earned by either spouse to be split equally, regardless of where they reside, complicating tax filings.

Tax Implications

Determining which state has the right to tax income is a key concern for spouses living in different states. Some states tax all income earned by their residents, regardless of where it was generated, while others only tax income earned within their borders. This can lead to situations where a spouse’s wages or investment earnings are taxed by multiple states. Many states offer credits for taxes paid to another jurisdiction, but these rules vary and don’t always eliminate double taxation.

Income sourcing rules also affect tax liabilities. If one spouse works remotely for a company based in another state, that state may claim the right to tax their wages. New York enforces the “convenience of the employer” rule, taxing remote employees as if they were working in the state unless their employer requires them to work elsewhere. This can result in unexpected tax bills for couples living apart due to employment circumstances.

State tax rates and deduction rules add further complications. A spouse in a high-tax state like California may face significantly higher tax burdens than one in a no-income-tax state like Florida. If both spouses are taxed in their respective states, they may need to adjust withholdings and estimated tax payments to avoid penalties. Differences in standard deductions, itemized deduction limits, and tax credits can also affect overall tax liabilities.

Marital Filing Status Options

Couples living in different states must carefully consider how they file their federal and state tax returns, as their choice can significantly impact their overall tax liability. The IRS allows married couples to file jointly or separately, each option carrying distinct advantages and drawbacks. Filing jointly often results in lower tax rates and access to benefits such as the Earned Income Tax Credit (EITC) and higher standard deductions. However, joint filing also means both spouses are equally responsible for any tax liability, including penalties or audits.

Filing separately may be beneficial when spouses have significantly different income levels or one has substantial deductions subject to adjusted gross income (AGI) limitations, such as medical expenses. In states that follow federal filing statuses, choosing “Married Filing Separately” at the federal level often requires the same status for state returns. This can be problematic in states with high tax rates or limited deductions for separate filers. Some states, such as Pennsylvania, mandate separate state filings for married taxpayers, regardless of their federal election, creating additional administrative burdens.

For couples residing in different states, the interaction between state tax laws and filing status can create further complexities. Some states allow joint returns even if only one spouse is a resident, while others require nonresidents to file separately. In community property states, filing separately may still require income to be split, complicating tax calculations. Understanding how each state treats joint and separate filings is necessary to avoid unintended tax liabilities or loss of deductions.

Documentation and Proof of Residency Requirements

Establishing residency in a state requires more than just living there; individuals must provide sufficient documentation to verify their intent to remain. States rely on legal, financial, and personal records to determine residency status. Lease agreements, mortgage statements, and utility bills showing consistent usage at a specific address are commonly accepted forms of evidence. Some states require an official declaration of domicile, legally affirming an individual’s intent to establish permanent residency.

Employment records and payroll documentation also play a role in residency determinations. Pay stubs reflecting state tax withholdings, employer-issued W-2s, and business registrations can support a claim of residency, particularly when combined with other indicators such as local professional licenses or business filings. States scrutinize these records to ensure individuals are not attempting to claim residency in a lower-tax jurisdiction while maintaining ties to a higher-tax state.
