Can I Still Visit My Parents? Day Counting for Real Life

People who have just moved states rarely ask about residency in the abstract. They ask a specific, slightly embarrassed question, usually some version of this: my parents are getting older, I go back one weekend a month, sometimes more when something goes wrong, and I need to know whether that is going to cost me. Nobody wants an answer that begins with "it depends on the totality of the circumstances." They want a number.

For two of the three states in this article there is a number, and it is smaller than most people assume. For the third there is no number at all, which is worse in one direction and better in another. And in all three, the count is not actually the first question. The first question is whether the state has a day-count test that applies to you, and that turns on something most people never think about: whether the house you sleep in when you visit is, in the state’s eyes, your home.

That last point is the one that changes outcomes. A person can visit 40 times a year and be untouchable. A person can visit 12 times and hand the state its whole case. The difference is usually not the frequency.

This is informational and is not legal or tax advice. Whether a given trip counts, and whether a given house is your abode, turns on your own facts. Work through them with a qualified CPA or tax attorney.

Start with the mechanical rule, because every intuition people bring to this is wrong in the same direction. New York’s regulation states that "presence within New York State for any part of a calendar day constitutes a day spent within New York State." That is 20 NYCRR 105.20(c), and the Appellate Division upheld it against challenge in Leach v Chu, 150 AD2d 842.

Apply that to an ordinary visit. You fly in Friday at 8 p.m., you have dinner Saturday, you leave Sunday afternoon. You were in your parents’ house for roughly 44 hours. New York counts three days. The Friday you arrived on is a day, because part of it was spent in New York. The Sunday you left on is a day, for the same reason. Nothing about the rule cares that two of the three were mostly spent somewhere else or asleep.

Run that forward and the arithmetic gets uncomfortable fast. One Friday-to-Sunday visit a month is 36 days a year, not 24. Add a week at Thanksgiving and Christmas and you are near 60. Add a bad year, the kind where a parent has a fall in March and a procedure in June and you go back for a stretch each time, and a person who thinks of themselves as visiting occasionally is somewhere north of 90 days without ever having made a decision about it.

New York’s own Nonresident Audit Guidelines acknowledge the rule reads harshly and then decline to soften it in any way that helps here. The guidelines note that a literal reading "could mean stepping over the state line for one second; however, no audit is ever expected to be based on such a minimal amount of time spent in New York. Common sense must prevail." Read that carefully. It is a promise not to build a case on a single absurd second at the state line. It is not a partial-day discount, and it is not an exception for visits. The guidelines say so directly in the next breath: "presence in New York for brief periods of time would normally constitute days in the state."

If you want to see what your own pattern actually adds up to before you assume it is fine, the day count checker runs the arithmetic against each state’s own threshold rather than the 183 everyone has in their head.

New York recognizes exactly two situations where physical presence does not produce a day. Both are worth knowing precisely, because both are routinely misremembered as broader than they are.

The first is travel. Under 20 NYCRR 105.20(c), presence is disregarded when it is solely for the purpose of "boarding a plane, ship, train or bus for travel to a destination outside New York State, or while traveling through New York State to a destination outside New York State." The guidelines are generous about what does not spoil this: "the purchase of meals or other items at a terminal, access to an automatic teller machine (ATM), stopping for gas or a meal while driving through New York, stopping to pick up a traveling companion on route to the terminal, parking the car in New York in order to meet a limousine or other conveyance that takes the individual to the airport or terminal should not change the treatment of this day as a travel day."

The test the guidelines apply is whether the activity is "incidental to his presence for travel purposes" and what "degree of control the taxpayer exercises over his travel arrangements." Their own illustration draws the line where you would expect: "someone who arrives a day early for a cruise, in order to attend a business meeting, would be present for that day, whereas time spent by someone who visits a friend during an unavoidable delay or stopover would not count."

Notice what that does to the connecting-flight theory people build their travel around. Changing planes at JFK on the way to somewhere else is a travel day. Changing planes at JFK and driving out to see your mother for the afternoon is not a travel day. It is a day. The visit is the whole point of the trip, which is the opposite of incidental.

The second exception is medical, and it is the one that matters most for the people asking this question, because a large share of them are going back for exactly that reason. The exception comes from Stranahan v State Tax Commission, 68 AD2d 250, where the Appellate Division held that when a nondomiciliary seeks treatment for a serious illness, time spent in a medical facility for that treatment is not counted. Audit policy is actually broader than the case: the guidelines state that "confinement to a medical institution for any reason in New York (serious or otherwise), does not constitute a day spent in New York."

Now read the limit. It covers the patient. It does not cover the visitor. The guidelines address this head on through Matter of Dr. Charles F. Brush III & The Estate of Ellen S. Brush, DTA No. 817204, where the question was whether to count the days a husband spent in New York City visiting his hospitalized wife. The ALJ concluded that Stranahan did not apply to his days, finding "no basis upon which to treat Mrs. Brush’s hospital days as non-New York City days for petitioner." Every day you spend at a parent’s bedside is a New York day. The exception belongs to the person in the bed.

The guidelines close the other obvious gap too. In Matter of Ralph and Leona Kern, 240 AD2d 969, the Appellate Division rejected the argument that days spent in New York City as an outpatient or visiting doctors fell under Stranahan, finding the contention "to be lacking in merit." Driving a parent to an appointment and driving home is a full day, and so is the day you took them for the follow-up.

Here is the part that gets skipped, and skipping it is why so many people worry about the wrong thing.

New York’s statutory residency test under Tax Law section 605(b)(1)(B) has two prongs, and both must be satisfied. A person who is not domiciled in New York is taxed as a statutory resident on worldwide income only if they maintain a permanent place of abode in New York for substantially all of the taxable year and spend more than 183 days of the year in the state. Exactly 183 does not trigger it. And critically, if there is no permanent place of abode, the day count does not matter at all. You can spend 200 days in New York visiting family and, on the statutory residency test alone, not be a statutory resident, because the first prong was never met.

That is the good news, and it is substantial. It is also the reason the real risk in a family-visit pattern is almost never the calendar. It is the house.

One timing detail is worth knowing because it moved recently in taxpayers’ favor. The Audit Division previously defined "substantially all of the taxable year" as a period exceeding 11 months. Beginning with tax year 2022, the guidelines define it as a period exceeding 10 months. A dwelling maintained for a shorter stretch than that falls outside the first prong.

The case that governs this is about a taxpayer and his parents, which is not a coincidence. In Matter of Gaied, John Gaied owned a multi-family house on Staten Island, two miles from his 24-hour service station, where his parents lived in one of the units. He paid all of their expenses because they had no income of their own, and he admitted to staying there occasionally in their apartment. The Department, the Tax Appeals Tribunal, and the Appellate Division all held that this was a permanent place of abode, on the theory the Tribunal stated plainly: "there is no requirement that the petitioner actually dwell in the abode, but simply that he maintains it."

The Court of Appeals unanimously reversed, finding "no rational basis for this interpretation," and held that "the taxpayer must, himself, have a residential interest in the property" for it to be a permanent place of abode. There must be "some basis to conclude that the dwelling was utilized as the taxpayer’s residence."

Gaied is a taxpayer win, and it is the reason a parent’s house is not automatically your abode. But read what it actually decides. It does not say a relative’s home can never be your abode. It says the state has to show you have a residential interest in it. The audit guidelines then spend several pages explaining what that looks like, and the factors are uncomfortably close to how a lot of people actually visit their parents.

The guidelines list what matters: whether you share in the expenses, whether you keep clothing or personal effects there, and whether "there is a dedicated room for one’s own use with free and continuous access." They note that in the analogous case of a parent maintaining an apartment for a child, whether it is an abode "may well depend on the physical aspects of the apartment," and that "a two-bedroom apartment would more likely constitute his PPA than a studio apartment lacking separate sleeping quarters." They add a separate factor that catches people who have never thought about it: using the address "to receive mail, for voter and car registrations, or for phone service would be evidence of such a relationship." In Matter of Rhoda Miller, DTA No. 812849, the Tribunal noted the taxpayer "occasionally received mail" at an apartment, including two 1099s, as part of finding it was her abode.

Set that against the ordinary facts of an adult child who moved to Florida. There is a bedroom that is still called your room. Your winter coat is in the closet. You have your own key. Some mail still arrives there because you never got around to changing one or two accounts, and one of them sends a 1099. You cover your parents’ property tax bill each year. Every one of those is on the list.

The counterweight is Matter of Louis A. & Amelia Panico, DTA No. 805810, where a Long Island home the taxpayers owned and paid the mortgage and phone bills on was held to be the abode of the daughter and grandchild who actually lived there, and not the taxpayers’. The ALJ reasoned that the taxpayers "could not have been expected to rent out the Medford house when it was, of necessity, occupied by their daughter and grandchild." The distinguishing facts were that the occupants lived there and the owners did not, and that the owners were in Arizona and spent three weeks in New York that year.

The practical reading for anyone moving from New York to Florida is that the visit itself is rarely the exposure. Keeping a dedicated room with your things in it, paying the household’s bills, and leaving the address on your paperwork is what converts a family home into your permanent place of abode, and that is what switches the day count on. Our New York residency guide rates the state 5 out of 5 on both exit stickiness and audit aggressiveness, and the enforcement detail it collects, including cell phone location records, E-ZPass and toll records, and credit and debit card statements, is aimed squarely at reconstructing exactly this kind of pattern.

New Jersey is the one state of the three that answers the question people are really asking with a figure they can plan around, and almost nobody knows it exists.

New Jersey’s statutory residency test mirrors New York’s. Under N.J.S.A. 54A:1-2(m), a resident is anyone domiciled in New Jersey, or anyone not domiciled there who maintains a permanent place of abode in the state and spends more than 183 days of the taxable year in it. Days are counted the same way; presence for any part of a day generally counts, though New Jersey’s published guidance is far less granular than New York’s regulation about specific travel-day situations.

The part worth knowing is the separate branch the Division of Taxation publishes for people who left. Its guidance states that you are a nonresident for tax purposes if "You did not maintain a permanent home in New Jersey; and You did maintain a permanent home outside of New Jersey; and You did not spend more than 30 days in New Jersey." That branch is available even to someone New Jersey would otherwise still treat as domiciled there, which is precisely the situation of a person whose move is recent and whose evidence of a new domicile is thin.

The Division states the other branch in the same place: you are also a nonresident if "New Jersey was not your domicile, and you spent 183 days or less here," or if "New Jersey was not your domicile, and you spent more than 183 days here, but you did not maintain a permanent home here."

So the answer for New Jersey has two versions depending on how confident you are. If your domicile change is clean and documented and you keep no permanent home in New Jersey, your ceiling is 183 days. If your domicile change is arguable, which it usually is in the first year or two, then 30 days is the number that makes the question moot, and one weekend a month puts you over it.

What makes this concrete rather than theoretical is Samuelsson v. Director, where the New Jersey Tax Court dismissed the Director’s assessment treating a departed family as full-year New Jersey residents. The house they left behind never sold and they moved back within a year, and they kept their nonresident months anyway, because the furniture had gone to Florida, the house had been listed for sale, the children were in Florida schools and the New Jersey bank accounts were closed. Anyone moving from New Jersey to Florida should read that case as being about whether the household actually relocated rather than about any single document, and our New Jersey residency guide collects the enforcement methods the Division uses to test it, including E-ZPass toll records, airline tickets, and comparison against prior years’ resident filing history.

California does not run a day-count test as its primary rule, and people leaving California consistently misread what that means.

Under Revenue and Taxation Code section 17014 and FTB Publication 1031, a resident is anyone present in California for other than a temporary or transitory purpose, or anyone domiciled in California who is outside the state for a temporary or transitory purpose. It is a closest-connections test. Publication 1031 frames the inquiry as: "Generally, your state of residence is where you have your closest connections," and instructs that "You should consider the purpose and length of your stay when determining your residency."

The only bright line runs the wrong way for people moving in, not for people visiting: "You will be presumed to be a California resident for any taxable year in which you spend more than nine months in this state." There is no symmetrical safe harbor beneath it. Spending 60 days in California does not make you safe the way spending 60 days in New Jersey does.

What Publication 1031 does offer is a worked example that is genuinely reassuring, and it is worth quoting because it describes a life a lot of people recognize. A business executive resides in New York with their family and travels to other states for business several times a year. "Your average stay is one or two weeks and the entire time spent in California for any taxable year does not exceed six weeks. Your family usually remains in New York when you are traveling." The determination: "Under these circumstances, you are not a California resident because your stays in California are temporary or transitory in nature."

Six weeks is 42 days. It is not a statutory threshold and FTB is not bound by it, but it is FTB’s own published illustration of a stay that stays temporary, and the facts doing the work are visible: the trips are short, they are for a defined purpose, and the family and the home are elsewhere. A monthly weekend to see parents in Sacramento, with a household plainly centered in Nevada, sits inside the logic of that example. A pattern where the visits get longer, the purpose blurs, and a spouse or child is still in the California house does not.

The risk for anyone moving from California to Nevada is that the absence of a number cuts the other way when the rest of the picture is weak. Our California residency guide rates the state 5 out of 5 on exit stickiness, and the reason is that FTB can find residency at a low day count when the closest connections are still in California. The domicile factors practitioners argue from come out of Appeal of Bragg, 2003-SBE-002, where a taxpayer who moved to an Arizona cattle ranch was held to be an Arizona resident on the objective facts, including how his days were actually spent, over his own later claim that he had never left California. Visiting your parents is one connection among nineteen. It is not the one that decides a Bragg-style case, but it feeds the factor about the state where the taxpayer's spouse and children reside.

There is one passage in New York’s audit guidelines that speaks more directly to this question than anything else the state has published, and it is both a concession and a warning.

The guidelines acknowledge that "taxpayers may not always leave a paper trail to substantiate their whereabouts on weekend days when they claim to be at home in their state of domicile," and instruct that in those situations "auditors should generally accept the taxpayer’s allegations absent evidence to the contrary such as a clear pattern of regularly being in New York on weekends."

Read both halves. If you have no records for a scattering of ordinary weekends at home in Florida, an auditor is told to take your word for it. But a standing weekly or monthly visit to your parents in New York is, in the guidelines’ own words, a clear pattern of regularly being in New York on weekends. That is the named exception to the concession. The moment the pattern is visible, the benefit of the doubt is gone, and it is gone for every weekend in the year, not just the ones you actually traveled.

That matters because of where the burden sits. The recordkeeping obligation is written into the regulation: "Any person domiciled outside New York State who maintains a permanent place of abode within New York State during any taxable year, and claims to be a nonresident, must keep and have available for examination by the Department of Taxation and Finance adequate records to substantiate the fact that such person did not spend more than 183 days of such taxable year within New York State." The guidelines add that the standard of proof is clear and convincing, the same standard applied to domicile.

The guidelines are explicit that this can be met in more than one way, quoting Matter of Julian H. & Josephine Robertson, DTA No. 822004, for the proposition that proof can consist of "testimonial evidence, documentary evidence, or a combination of the two." Past decisions have accepted contemporaneously maintained diaries or calendars supported by credible testimony, and in one case credible testimony alone. What they will not accept is a reconstruction built after the notice arrives, against a visible pattern, with nothing contemporaneous behind it.

It is also worth knowing what the state pulls to test your version. The guidelines list personal diaries and calendars in written or electronic form, credit card statements and receipts, bank records including ATM receipts that "indicate the location of withdrawals," telephone records for both residences, utility bills reflecting regular or seasonal use, flight itineraries, hotel receipts, E-ZPass records, and office building swipe cards. Auditors are also instructed to visit the New York dwelling in person, including "checking the names on the mailbox, checking the license numbers of any vehicles on the premises, interviewing the doorman, building superintendent and mailman, if necessary."

The guidelines give one worked example of how a day gets resolved, and it shows how thin the margin is. If phone bills show calls made from the Connecticut home from early morning until late afternoon and nothing places the taxpayer in New York, it is reasonable to conclude they were not in New York. But that presumption "would not apply if phone bills for the New York residence showed calls on the same day," or "where the taxpayer has demonstrated a pattern of being in both locations on the same day."

Everything above is about statutory residency, the mechanical test. Domicile is the other test, and it is worth separating them, because people conflate the two and end up frightened of the wrong thing.

Two New York determinations in our own case research make the point better than any general statement could. In Matter of Blatt, DTA No. 826504, an IAC general counsel who became CEO of Match in Dallas proved by clear and convincing evidence that he had changed his domicile to Texas in November 2009, and a notice of deficiency for $430,065 was canceled. He kept his owned Manhattan apartment and a Hamptons boat the entire time. His Texas driver’s license and voter registration did not come until April and May of 2010. The ALJ held that his dog "was his near and dear item which reflected his ultimate change in domicile to Dallas," and expressly declined to adopt either side’s detailed day counts, since he was under 183 days in New York in both years anyway.

In Matter of Patrick, DTA Nos. 826838 and 826839, a taxpayer who claimed a change of domicile from New York City to Paris won, and deficiencies asserting $1,681,160 in tax, or $2,189,743.84 with interest and penalties, were canceled. The Division counted 168 New York days against 82 Paris days in 2011, and 183 New York days against 92 Paris days in 2012. He spent roughly twice as much time in New York as in the place he claimed as home, and still prevailed on domicile, because the ALJ credited the evidence of genuine intent, including his reunion and marriage to a woman he had not seen in nearly 40 years.

Read those two together. On the domicile question, spending significant time in your former state is survivable when the life you built elsewhere is real and documented. Nobody loses a domicile case because they saw their mother once a month. What loses domicile cases is a move that exists on paper and not in fact, which is the distinction Samuelsson draws on the New Jersey side when it credits a relocation that was messy on paper and complete in substance. Bragg makes the California version of the point from the other direction. That taxpayer had genuinely moved, and the objective record of how he spent the year beat the California residency he later tried to claim on an amended return. The test reads conduct either way.

The statutory residency test is the unforgiving one, and it is unforgiving precisely because it does not care about your intent, your reasons, or how sympathetic the trip was. It is two facts and a threshold. That is why the abode question deserves more of your attention than the calendar does.

The practical version of all of this is short, and none of it requires seeing your parents less.

Find out which prong applies to you before you count anything. If you have no permanent place of abode in your former state, New York’s and New Jersey’s day thresholds do not reach you, and the exercise is about domicile evidence instead. If you do have one, or might, the count becomes the whole game.

Look honestly at whether the house you stay in is becoming your abode. The factors are a dedicated room with free and continuous access, personal effects kept there, sharing in the household expenses, and the address appearing on mail, voter registration, vehicle registration, or phone service. You can visit exactly as often as you do now and still fail every one of those tests, which is the objective. Move the mail, move the registrations, do not keep a standing room with your things in it, and if you support your parents financially, understand that the guidelines treat sharing in the expenses as one factor among several rather than as decisive on its own.

Know your real ceiling. In New Jersey it is 30 days if your domicile change is still arguable and 183 if it is not. In New York it is 183, but only if the abode prong is met. In California there is no ceiling, and Publication 1031’s six-week example is an illustration rather than a rule.

Count arrival and departure days, because the state will. The single most common error in a self-assessed day count is treating a three-calendar-day trip as two days of presence.

Keep the record while the year is happening. The guidelines accept contemporaneous calendars supported by credible testimony and reject reconstructions that contradict a visible pattern. The evidence that resolves a disputed weekend is the flight itinerary, the toll record, the card transaction in the state you say you were in, and the phone record, gathered as they occur rather than subpoenaed back three years later.

Do not rely on the exceptions to cover a family visit. The travel exception covers passing through, not stopping to see someone. The medical exception covers the patient, not the visitor, and after Brush and Kern that is settled enough that arguing it wastes the audit rather than winning it.

And if a parent’s health is the reason the day count is climbing, deal with it as a planning problem in advance rather than a documentation problem afterward. Those are the years where the count moves fastest and the records are thinnest, because nobody is thinking about tax while it is happening.

The Mobility Map records days and nights by state as they happen and measures them against each jurisdiction’s own threshold rather than a generic 183, which is the difference between knowing you took twelve trips and knowing you accumulated 41 New York days. Evidence Vault holds the records that resolve a contested weekend: itineraries, toll and transit records, card activity in the state you say you were in, and the documentation of where the household actually sits. AuditIQ surfaces thin days and unresolved former-state ties in the states that still have a claim on you, including the abode question that decides whether the day count applies at all. Advisor sharing lets a CPA or tax attorney review the chronology and the underlying documents directly rather than reconstructing them from memory.
