When Multi-State Filing is Required

You may need to file in multiple states if you:

• Moved from one state to another during the year
• Work in a different state than where you live
• Own rental property or a business in another state
• Earned income from sources in multiple states

Residency Rules

Resident

• Domicile in the state, OR
• Maintained a permanent place of abode AND spent more than 183 days in the state (varies by state)
• File as resident, report all income

Part-Year Resident

• Moved into or out of state during the year
• File part-year resident return
• Apportion income based on residency periods

Nonresident

• Live in another state
• Earned income from sources in the state
• File nonresident return
• Report only state-source income

Avoiding Double Taxation

Credit for Taxes Paid to Other States

Most states provide a credit for income taxes paid to other states on the same income to prevent double taxation. Generally:

• Resident state: Report all income, credit for tax paid to other states
• Nonresident state: Tax only source income from that state

Reciprocal Agreements

Some states have reciprocal agreements allowing residents of one state to work in another without paying nonresident income tax:

Examples:

• IL/IA/KY/MI/WI reciprocity
• MD/DC/VA reciprocity
• PA/IN/MD/NJ/OH/VA/WV reciprocity

Requires: Filing exemption certificate with employer

Special Situations

Remote Workers

Remote work creates multi-state tax issues:

• “Convenience of employer” rules (NY, NE)
• Temporary vs. permanent work location
• State sourcing of wages
