When it comes to multi-state taxation, the rules can be complex, especially if you live or work in multiple states. Let’s break it down step by step with easy-to-understand examples and explanations.
Resident Tax Returns
To begin with, states follow one of four main patterns for calculating tax liability on income tax returns for residents:
- Federal AGI as a Starting Point
First, many states start with your federal Adjusted Gross Income (AGI) and adjust for state-specific additions and subtractions. You might be allowed to deduct standard or itemized deductions, personal exemptions, or even receive credits for these exemptions. - Federal Taxable Income as a Starting Point
Some states begin with federal taxable income. As a result, any standard or itemized deductions are already included. Then, state-specific changes are applied. - State-Defined Income
A few states don’t use federal numbers. Instead, they base income inclusion and exclusions solely on state law. As with the other patterns, deductions and credits may still be available. - Investment Income Only
States like New Hampshire and Washington focus only on specific types of income. For example, New Hampshire taxes interest and dividend income, while Washington only taxes capital gains.
Part-Year Resident Returns
If you were a resident of more than one state during the year, states usually calculate your tax in one of two ways:
- AGI Received While a Resident
The first method involves calculating the income you earned while living in the state, then prorating deductions based on the portion of the year you lived there. - Prorate Tax as if a Full-Year Resident
Alternatively, some states calculate your tax as if you were a full-year resident and then prorate that tax based on your time in the state.
Nonresident Returns
If you earned income in a state where you don’t live, here’s how your taxes might be calculated:
- State-Source AGI
Nonresidents calculate tax based on the income derived from the state’s sources. Deductions and exemptions, if available, are then prorated. - Prorate Tax as if Full-Year Resident
Some states calculate the tax as if you were a full-year resident and then prorate it based on the income earned from state sources.
Special Rules: Servicemembers Civil Relief Act
Military families may benefit from special rules under the Servicemembers Civil Relief Act. A military spouse’s legal residence doesn’t change based on relocation due to military orders, and they can choose to be taxed in their spouse’s home state or duty station.
States with Reciprocal Agreements
Certain states have agreements that allow you to avoid double taxation if you live in one state but work in another. For example, residents of the District of Columbia don’t need to file in neighboring states like Maryland or Virginia if wages are their only income source.
Plan Ahead
Lastly, always remember that understanding your multi-state tax obligations can help you avoid unnecessary payments and penalties. Be sure to consult your state’s tax booklet or a tax professional to ensure you’re following the correct procedures.
