# Connecticut Tax Residence

Tax residency rule, United States. Page: https://usecountr.com/trackers/tax-us-ct-statutory/

## Summary

Connecticut treats you as a resident for income tax, even if your permanent home is in another state, when you maintain a permanent place of abode in Connecticut and are in the state for more than 183 days of the calendar year. The 184th day crosses the line. Any part of a day counts, except a part of a day when you are only in transit to a place outside Connecticut. A resident pays Connecticut income tax on income from all sources. The Department of Revenue Services (DRS) applies the test and can ask for records of your days.

- Limit: More than 183 days in Connecticut (the 184th day crosses the line)
- Period: The taxable year, for most people 1 January to 31 December
- A day counts when: You are in Connecticut for any part of the day, unless only in transit
- Second condition: A permanent place of abode in Connecticut
- Law: Conn. Gen. Stat. section 12-701(a)(1)(B), regulation 12-701(a)(1)-1
- Run by: Connecticut Department of Revenue Services (DRS)

## Who it applies to

- New Yorkers who own a house in Fairfield or Litchfield County and spend long summers and many weekends there.
- People who moved their domicile to Florida and kept the family home in Connecticut.
- Employees from another state who take a lease in Connecticut that has no fixed end.
- People from other countries who keep a home in Connecticut and travel in and out during the year.

## The rule

Section 12-701(a)(1) of the Connecticut General Statutes defines a resident of the state in two parts. Part (A) covers people domiciled in Connecticut, which means Connecticut is the place they intend as their permanent home. Part (B) covers a person who is not domiciled in Connecticut but maintains a permanent place of abode in the state and is in the state for an aggregate of more than 183 days of the taxable year. An aggregate means the days are added together across all visits.

The DRS regulation, section 12-701(a)(1)-1, gives the details. For counting, a day spent in Connecticut includes any part of a day, except a part of a day when you are present only while in transit to a destination outside Connecticut. A person with a Connecticut abode who claims to be a nonresident must have records that show they spent 183 days or fewer in the state.

The regulation defines a permanent place of abode as a dwelling place permanently maintained by you, whether or not you own or lease it. It generally includes a dwelling owned or leased by your spouse. A camp or cottage that is fit and used only for holidays is not one. A barracks, a motel room, or a building without the normal facilities of a home, such as for cooking and bathing, is generally not one either. A place kept only during a temporary stay for a particular purpose is not permanent. The regulation gives the example of an employee sent to a Connecticut office for a fixed and limited period.

The DRS guidance for the 2025 taxable year describes this group as people who maintained a permanent place of abode in Connecticut during the entire taxable year and spent more than 183 days there. The Department looks at the whole situation. People domiciled in Connecticut face a different limit, 30 days, which the Connecticut Tax — 30 Days or Fewer tracker follows.

Why it exists: Connecticut taxes residents on all income and nonresidents only on Connecticut income. Many people with homes in the state work in New York or spend winters in the south and could name another place as their permanent home. The test stops the tax from depending only on a statement of intention. A home that is always available, and more than half of the year in the state, is treated as enough of a connection.

## Counting the days

You count the days of the taxable year on which you were in Connecticut for any part of the day. Days of pure transit to a place outside the state are left out.

1. Write down every dwelling in Connecticut that you or your spouse own, lease or otherwise keep, and decide whether it is permanent or only for a temporary, fixed purpose.
2. Mark each day of the year on which you were in Connecticut at any time.
3. Count arrival days and departure days as full days.
4. Remove days when you were in the state only in transit, for example driving on Interstate 95 from New York to Rhode Island without stopping for another reason.
5. Add up the days. 184 or more, together with the permanent place of abode, makes you a resident.
6. Keep the records behind your count, because the regulation expects you to have them.

How Countr counts it: Countr counts every calendar day on which your phone was in Connecticut at any time, from 1 January to 31 December, against a limit of 183 days. It cannot see whether you maintain a permanent place of abode, so add this tracker only if you do. It also counts days of pure transit, because it cannot tell a drive through the state from a visit. Its number can be a little higher than the legal count and is never lower, so the warning comes early.

## Examples

### A long season at the lake house

Helen is domiciled in Manhattan and owns a house in Litchfield County that can be lived in all year. In 2026 she stays there from 1 May to 31 October without leaving the state. May, June, July, August, September and October have 31, 30, 31, 31, 30 and 31 days, which is 184 days. With the house and more than 183 days she is a Connecticut resident for 2026.

### One day shorter

The next year Helen arrives on 2 May and again leaves on 31 October. That is 183 days. She comes back for no other visits. 183 is not more than 183, so she does not meet the day part of the test and stays a nonresident. A single lunch in Greenwich in December would have changed the result.

### A fixed work posting

Omar is domiciled in Ohio. His employer sends him to its Hartford office from 1 January 2026 for a fixed period of 18 months, after which he must return. He rents a flat in Hartford and spends 250 days in Connecticut in 2026. The regulation says a place kept only during a temporary stay for a particular purpose is not permanent. He is taxed as a nonresident on his Connecticut pay, not as a resident.

## Exceptions

- A person who is not domiciled in Connecticut and is in active service in the armed forces of the United States is outside this test.
- A part of a day when you are present only while in transit to a place outside Connecticut does not count as a day.
- A place of abode kept only during a temporary stay for a particular purpose is not permanent.
- A dwelling you own but have leased for at least one year to people not related to you or your spouse, with no right for you to use any part of it and not used as your mailing address, is generally not your abode during the lease.
- A holiday camp or cottage used only for holidays, a motel room and a barracks are generally not permanent places of abode.

## Common misconceptions

- "I live in New York, so my Connecticut weekend house cannot make me a resident." Domicile in New York does not protect you. A permanent place of abode in Connecticut with more than 183 days there makes you a Connecticut resident as well.
- "Driving through Connecticut to Boston uses one of my days." Presence only in transit to a place outside the state does not count. If you stop for a reason other than the journey, such as a visit to your house, the day counts.
- "Any apartment I rent in Connecticut is a permanent place of abode." A place kept only for a temporary stay for a particular purpose, such as a work assignment with a fixed and limited term, is not permanent under the regulation.
- "Half days count as half." There are no half days. Any part of a day in the state is one whole day.

## Questions and answers

### Is day 183 in Connecticut safe?

Yes. The statute says more than 183 days, so 183 days does not meet the test. The 184th day does, if you also maintain a permanent place of abode.

### Does the day I arrive in Connecticut count?

Yes. A day in Connecticut includes any part of a day. The day you arrive and the day you leave both count, unless you were only in transit to a place outside the state.

### What records does Connecticut expect?

The regulation says a person who has a Connecticut abode and claims to be a nonresident shall have records available to show they spent 183 days or fewer in the state. Travel records, receipts, phone location history and a calendar are the usual evidence.

### Can I be a resident of Connecticut and New York at once?

Yes. You can be domiciled in one and meet the abode and day test in the other. Each state then treats you as a resident under its own law.

### Does a house owned only by my spouse count?

Generally yes. The regulation says a permanent place of abode generally includes a dwelling place owned by or leased to your spouse.

### Do days working remotely from my Connecticut house count?

Yes. The reason you are in the state does not matter for the count. A day at the house working, resting or visiting is a Connecticut day.
