Understanding Connecticut's Non-Resident Income Tax Laws

If you are a non-resident of Connecticut (CT) and receive income from a Connecticut source, you must file a Form CT-1040NR/PY, Connecticut Nonresident and Part-Year Resident Income Tax Return. Gross income includes income from sources within and outside Connecticut, such as wage income, interest income, and income from business or employment activities in Connecticut. Nonresident aliens must also file a Connecticut income tax return if they meet the gross income test, which includes any income not subject to federal income tax under an income tax treaty. Connecticut residents are those domiciled in Connecticut for the entire tax year or those who have maintained a permanent place of abode in Connecticut and spent over 183 days in the state during the taxable year.

Nonresident income tax return

If you are a non-resident of Connecticut, you must file a Connecticut income tax return if you meet the requirements of Form CT-1040NR/PY. This form is for nonresidents or part-year residents of Connecticut.

To determine whether you meet the requirements, you must take a gross income test. This means that you must take into account any income not subject to federal income tax under an income tax treaty between the United States and your country of citizenship or residence. Income tax treaty provisions are disregarded for Connecticut income tax purposes. Any treaty income reported on federal Form 1040NR and not subject to federal income tax must be added to your federal adjusted gross income.

If you are a nonresident alien and do not have a Social Security Number (SSN), you must obtain an Individual Taxpayer Identification Number (ITIN) from the Internal Revenue Service (IRS) and enter it in the space provided for an SSN.

You must file Form CT-1040NR/PY if you meet the gross income test and had any Connecticut source income. For example, a nonresident single individual who receives $15,000 in wage income from Connecticut employment and $1,000 in federally-exempt interest from California state bonds must file Form CT-1040NR/PY because their gross income is $16,000.

You can file your Connecticut income tax return electronically through the CT Department of Revenue Services myconneCT online application or approved third-party software (MEF).

Gross Income Test

If you are a non-resident alien in Connecticut, you must file a Connecticut income tax return if you meet the requirements of the Gross Income Test. This test determines whether your gross income exceeds the minimum requirement, which is currently set at $100,000. Gross income generally includes all income received from various sources, such as money, goods, property, or services, that are not exempt from federal income tax.

When applying the Gross Income Test, it is essential to consider any income that may not be subject to federal income tax due to tax treaties between the United States and your country of citizenship or residence. Any income reported on federal Form 1040NR that is exempt from federal income tax must be added to your federal adjusted gross income. This adjusted gross income is then used to determine if you meet the minimum requirement for Connecticut's Gross Income Test.

For example, if a nonresident single individual earns $15,000 in wage income from Connecticut employment and receives $1,000 in federally exempt interest from California state bonds, their gross income would be $16,000. Since this amount does not exceed the minimum requirement of $100,000, they would not be required to file a Connecticut income tax return based on the Gross Income Test.

On the other hand, if a nonresident individual has gross income exceeding $100,000, and the income is from a Connecticut source, they must file Form CT-1040NR/PY. This form is specifically for nonresident and part-year resident individuals in Connecticut. It's important to note that nontaxable Social Security benefits are not included in gross income, so a Connecticut part-year resident receiving such benefits may not be required to file a return unless Connecticut tax was withheld or estimated tax payments were made.

Additionally, if you are a nonresident alien without a Social Security Number (SSN) and are ineligible for one, you must obtain an Individual Taxpayer Identification Number (ITIN) from the Internal Revenue Service (IRS). This ITIN will be used in place of an SSN when filing your Connecticut income tax return.

Tax treaty provisions

For non-residents of Connecticut (CT), the state's income tax rules can be complex, and there are specific provisions for those who are considered nonresident aliens. To understand the tax treaty provisions, it is essential to determine whether an individual meets the criteria for filing Form CT-1040NR/PY.

Firstly, nonresident aliens must determine whether they meet the gross income test. This involves considering any income that is exempt from federal income tax due to tax treaties between the United States and the individual's country of citizenship or residence. It is important to note that while these tax treaty provisions are considered for the gross income test, they are disregarded for Connecticut income tax purposes. Any income reported on federal Form 1040NR that is exempt from federal income tax due to a tax treaty must be added to the individual's federal adjusted gross income. This adjusted amount is then used for Connecticut tax calculations.

Additionally, nonresident aliens should obtain a Social Security Number (SSN) if eligible. If not eligible for an SSN, they must obtain an Individual Taxpayer Identification Number (ITIN) from the Internal Revenue Service (IRS) and use it in place of the SSN on the relevant tax forms.

It is worth noting that the criteria for being considered a nonresident of Connecticut are specific. An individual is considered a nonresident CT state tax filer if their legal residence is outside of CT, and they do not maintain a permanent place to live in CT for the entire tax year. Even spending more than 183 days at their permanent place of residence outside of CT can qualify them as a nonresident. However, if they maintain a permanent place of abode in CT but spend 30 days or less in the state during the tax year, they may still be considered a nonresident.

Connecticut residency requirements

To be considered a Connecticut resident for tax purposes, an individual must be domiciled in Connecticut for the entire tax year. This means that they must maintain a permanent place of abode in Connecticut and spend more than 183 days in the state during the tax year.

If an individual moves to or from Connecticut during the tax year, they are considered a part-year resident. Part-year residents may not elect to be treated as residents for tax purposes. If one spouse is a resident and the other is not, they must file separate returns unless they elect to file a joint return, in which case their income will be taxed as if both spouses are residents.

Nonresidents and part-year residents must file a Connecticut Nonresident and Part-Year Resident Income Tax Return (Form CT-1040NR/PY) if they meet certain requirements, such as having income from Connecticut sources or making estimated tax payments to Connecticut. Nonresident aliens must file a Connecticut income tax return if they meet the requirements of Form CT-1040NR/PY, including taking into account any income not subject to federal income tax under an income tax treaty.

To file Connecticut tax returns electronically, individuals can use the CT Department of Revenue Services myconneCT online application or approved third-party software. They must authenticate their information using their Federal Adjusted Gross Income from recently filed tax returns, a valid Connecticut driver's license, or a Connecticut non-driver ID.

Connecticut income sources

For Connecticut, gross income generally means all income received from all sources in the form of money, goods, property, or services, not exempt from federal income tax. Gross income includes income from sources within and outside Connecticut.

Nonresidents who earn a gross income exceeding a certain threshold must file a Connecticut income tax return. For 2016, the threshold was $12,000 for those filing as married filing separately, and $24,000 for those filing as married filing jointly. Nonresidents must file Form CT-1040NR/PY, Connecticut Nonresident and Part-Year Resident Income Tax Return.

Connecticut nonresidents must take into account any income not subject to federal income tax under an income tax treaty between the United States and their country of residence. Any treaty income reported on federal Form 1040NR and not subject to federal income tax must be added to the federal adjusted gross income.

Connecticut nonresidents may also be eligible for certain tax credits, such as the ABLE account tax credit, which applies to contributions made by taxpayers into the ABLE accounts of their employees.

Additionally, Connecticut residents are those who are either domiciled in Connecticut for the entire tax year or have maintained a permanent place of abode in Connecticut and spent a total of more than 183 days in the state during the taxable year.
