What Happens If You Work in a Different State Than You Live?

Working in a different state than where you live introduces tax and payroll complexities. Understanding these implications helps individuals manage their financial obligations accurately. This situation requires careful attention to state-specific rules, which differ across the United States.

Understanding State Income Tax Rules

When an individual lives in one state but works in another, “taxable situs” determines where income is earned and taxable. Wages are taxable in the state where the work is physically performed, meaning income earned in a work state is subject to that state’s income tax laws, regardless of where the employee resides.

Many states have established income tax reciprocity agreements. These agreements allow residents of one state who work in a reciprocal state to pay income tax only to their state of residence, not the work state. For example, Pennsylvania has reciprocity agreements with states like Indiana, Maryland, New Jersey, Ohio, Virginia, and West Virginia. A Pennsylvania resident working in Ohio would pay income tax only to Pennsylvania if they file the exemption form with their employer. If a reciprocity agreement is in place, the employee needs to submit an exemption form to their employer in the work state to prevent taxes from being withheld there.

In situations where no reciprocity agreement exists, individuals might face taxation in both their work state and their resident state. To prevent double taxation on the same income, states offer a credit for taxes paid to other states. This credit is claimed on the resident state’s tax return, allowing the taxpayer to offset their resident state tax liability by the amount of tax paid to the non-resident work state. This prevents the income from being taxed twice.

A unique scenario arises when an individual works in a state that does not levy an income tax, such as Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, or Wyoming. In such cases, the individual would not owe state income tax to the work state. However, they would still be subject to income tax in their state of residence, as resident states tax all income earned by their residents, regardless of source.

Employer Responsibilities and Withholding

Employers face obligations when their employees work across state lines. Determining which state’s income tax to withhold is based on the physical location where the work is performed. An employer must generally withhold taxes for the state where the employee is working. If a reciprocity agreement exists, the employer may withhold taxes only for the employee’s state of residence, provided the employee has submitted the necessary exemption forms.

The employee’s accurate completion of federal Form W-4 and any state-specific withholding forms is important for correct tax withholding. These forms provide the employer with the information needed to calculate the state income tax to deduct from each paycheck. For instance, California requires employees to complete Form DE 4 for state income tax withholding, separate from the federal W-4. Similarly, Illinois has Form IL-W-4, and New Jersey uses Form NJ-W4.

Beyond withholding, employers may also need to register in the work state for tax purposes. The presence of an employee performing duties in a state can create “nexus,” a legal term indicating a sufficient connection to trigger tax obligations for the employer in that state. This registration ensures the employer can legally withhold and remit taxes to the correct state authorities.

Filing Your State Tax Returns

When an individual lives in one state and works in another without a reciprocity agreement, they need to file a non-resident tax return in the state where income was earned. This return reports the income sourced to that work state. The individual then files a resident tax return in their state of residence.

The non-resident state return should be completed first. Information from the non-resident return, specifically the amount of tax paid to the work state, is often necessary to correctly calculate the credit for taxes paid to other states on the resident state return. The resident state provides this credit to prevent the same income from being taxed by two different states.

These include the non-resident income tax return for the work state (e.g., New York’s Form IT-203 for non-residents), the resident income tax return for their home state, and specific credit forms or schedules that allow them to claim the credit for taxes paid to the non-resident state. For example, Virginia provides Schedule OSC for claiming this credit. The credit claimed is for the actual tax liability to the other state, not just the amount withheld from paychecks.

Other State Payroll Considerations

Beyond income tax, working in a different state than where one lives involves other state-level payroll considerations. Unemployment insurance is typically governed by the laws of the state where the work is performed. This means that an employee’s eligibility for unemployment benefits and the amount they might receive are generally determined by the work state’s regulations, as the employer usually pays unemployment taxes to that state.

Workers’ compensation is another area with state-specific rules. These laws are typically governed by the state where the work is physically performed, which dictates the coverage and claims process for work-related injuries or illnesses. Employers must comply with the workers’ compensation requirements of the work state, which can vary significantly in terms of coverage limits and reporting procedures.

Some states also have additional payroll taxes or benefits that might be impacted by interstate employment. For instance, a few states, such as California, Hawaii, New Jersey, New York, and Rhode Island, operate State Disability Insurance (SDI) programs. These programs provide partial wage replacement for non-work-related illnesses or injuries, and employers may need to contribute to or withhold for these programs based on the employee’s work location.
