Dual tax residency occurs when two jurisdictions (countries or states) treat you as a resident for tax purposes, potentially leading to double taxation on worldwide income. To mitigate this, tax treaties or state reciprocity agreements often apply, allowing taxpayers to claim credits for taxes paid to one jurisdiction on the return of the other.
A dual status individual is one who changes their tax status during the current year. Dual status individuals determine their U.S. residency status under both the Internal Revenue Code and tax treaties. A dual status individual must file a dual status return as described in Publication 519, U.S. Tax Guide for Aliens.
Powerful U.S. Protections Against Double Taxation
The U.S. provides three primary tools specifically designed to prevent dual citizens from paying taxes twice on the same income: the Foreign Earned Income Exclusion, Foreign Tax Credit, and international tax treaties.
Can You Be a Resident of Two States? You can be a resident of two states at the same time, usually by maintaining a domicile in one state and spending 183 days or more in another. It is not advisable, as you will be liable to file income taxes in both states, rather than in only one.
The rules for residency vary by state, but most define a resident as an individual who is in the state for more than 183 days in a year. This is commonly known as the 183-day rule. It's important to keep track of where you spend your time since residency can lead to additional tax liability.
You are a resident of the United States for tax purposes if you meet either the green card test or the substantial presence test for the calendar year (January 1 – December 31). Certain rules exist for determining your residency starting and ending dates.
A primary residence, also known as a principal residence, is generally the home that you live in for most of the year. You can only have one primary residence, so you can't live in two homes an equal amount of time and have them both be your primary residence.
The IRS defines a primary residence (or principal residence) as the home where you live for most of the year, the one you spend the most time in, and typically the one listed on your tax returns, voter registration, and driver's license. While it's the home where you live most often, you can only have one principal residence at a time, and factors like proximity to your job and where you file your taxes help establish its status.
Many states that collect income taxes use the 183-day rule to decide who is considered a resident of their state. According to the rule, if you spend at least 183 days of a year in a state — even if you have established your domicile in another state — you are considered a resident of the state for tax purposes.
Unsurprisingly, most states define a nonresident as a person who is not a resident of their state, generally meaning they're simply passing through or staying in the state for just a short period of time.
Dual Citizenship at Birth
If you were born a dual citizen, you may be able to avoid the exit tax—but only if: You still hold citizenship in your other country at the time of expatriation. You have been a U.S. resident for no more than 10 of the last 15 years (as defined for tax purposes).
Federal regulators routinely examine banks for compliance. For example, if a customer regularly sends wires to the UK, a bank may want to know if that customer is a dual citizen of the United States and the UK.
Yes, dual citizens often have tax filing obligations in both countries, but you usually don't pay double the tax due to tax treaties and credits (like the Foreign Tax Credit), which prevent full double taxation by letting you subtract foreign taxes paid from your U.S. liability or exclude certain foreign income, though reporting is still required for worldwide income. The U.S. taxes citizens on worldwide income regardless of residence, while other countries typically tax residents on their income.
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.
The "90-day rule" for non-residents typically refers to two different concepts: in U.S. immigration, it's a guideline for determining if a non-immigrant misrepresented their intent by engaging in certain activities (like unauthorized work or immediate marriage) within 90 days of arrival, leading to visa fraud or inadmissibility. In Canadian tax law, the 90% rule allows non-residents to claim full federal tax credits if 90% or more of their world income is from Canadian sources, otherwise, credits are prorated.
Yes, it is possible to have residency in two states – but there are a few asterisks attached to that “yes.” Residency rules vary from state to state, and what's allowed in one place might not fly in another.
The biggest tax mistakes people make include filing late, math errors, incorrect personal info (like Social Security numbers), forgetting deductions/credits (like EITC), misreporting income, not signing forms, and making errors with bank details for direct deposit, all leading to delays, penalties, or missed savings, with using tax software or professionals helping avoid these common pitfalls.
The answer to this question is yes. The IRS can seize some of your property, including your house if you owe back taxes and are not complying with any payment plan you may have entered. This is known as a tax levy or tax garnishment.
If you use your former home to produce income (for example, you rent it out or make it available for rent), you can choose to treat it as your main residence for up to 6 years after you stop living in it. This is sometimes called the '6-year rule'. You can choose when to stop the period covered by your choice.
Mortgage interest on a second home is tax deductible within the same limits as the mortgage on your first home. Property taxes paid on additional homes can also be tax deductible, regardless of the number of homes you own.
