Multi-state tax applies when income is earned across state lines, requiring taxpayers to file returns in both their resident state and any non-resident state where they worked or earned income. Generally, the work state taxes income earned there, while the home state taxes all income but offers a tax credit for taxes paid to the other state to prevent double taxation.
Living in two states means you'll likely file part-year resident returns in both states if you moved, or a resident return and a nonresident return if you live in one state and work in another, but you usually avoid double taxation through credits for taxes paid to the other state. You must file in your home state and any state where you earn income, but credit rules prevent paying full tax twice on the same money, especially with reciprocity agreements or state tax credits.
Filing taxes for multiple states when you work across state lines
I currently live in a different state than where my employer is, how will state taxes work? The general rule is: your report all your income on your home state return, even the income earned out of state. You file a non-resident state return for the state you worked in and pay tax to that state.

Typically, a state can treat you as a resident for tax purposes if you're domiciled there or meet its statutory residency test. As a result, you can qualify for tax residency in multiple states, which may lead to double taxation on your income.
To avoid double taxation, use "pass-through" business structures like LLCs or S Corporations where profits are taxed only once at the owner's individual rate, instead of C Corporations which are taxed at the corporate level and again on dividends; alternatively, C Corp owners can pay salaries, retain earnings strategically, or use income splitting, while international earners rely on foreign tax credits or treaty provisions.

If an employee works in more than one state, income tax might need to be withheld for multiple states. In fact, at times the employer might need to withhold income tax for multiple states from the wages of one employee.
You'll have to file two state income tax returns instead of one: a resident tax return and a nonresident tax return. On your resident tax return (for your home state), you list all sources of income, including that which you earned out of state.
Most states use the 183-day rule to determine residency. If you spend more than 183 days in a state, you may be considered a statutory resident, even if your domicile is elsewhere. This can lead to dual residency, where both states claim you as a resident, potentially resulting in double taxation.
Contrary to popular belief, there's nothing in the U.S. Constitution or federal law that prohibits multiple states from collecting tax on the same income. Although many states provide tax credits to prevent double taxation, those credits are sometimes unavailable.
The IRS "10k rule" primarily refers to the requirement for businesses and financial institutions to report cash transactions over $10,000 by filing Form 8300 (for businesses) or a Currency Transaction Report (CTR) (for banks), under the Bank Secrecy Act.
