Dual-Status Tax Year: Filing the Year You Move To or Leave Italy

Picture this: you land in Italy in early summer, your US paychecks stopped in June, and a few months later your Italian accountant tells you Italy wants to tax your entire year, including January wages you earned in Ohio. A move year can leave you as a part-year taxpayer in one country and a whole-year taxpayer in the other, with deadlines on both sides. This guide walks through arrival-year and departure-year filings, the 183-day test, and how to file without paying twice.

What a Dual-Status Year Really Means for Italy Movers

I moved to Bologna with two suitcases, a cat carrier, and a folder of paperwork I thought was complete. It wasn’t. The paperwork that caused me the most stress didn’t come from the Questura or the comune. It came from my first tax season, when I learned that the US and Italy count the year of a move in completely different ways. I learned that by being wrong first, so you don’t have to.

“Dual-status” gets used loosely in expat circles, and that causes confusion. Strictly speaking, it is a US term for a year in which a person is a US resident for part of the year and a nonresident for the rest. Most people use it more broadly to mean the year you change countries. In that year your life is split between two places, but two tax systems may each claim more of it than you expect.

Two Countries, Two Calendars, One Messy Year

Both the US and Italy use the calendar year as the tax year, which sounds tidy. The trouble is that the two systems decide who you are for that year in different ways. The US taxes its citizens on worldwide income every year, wherever they live. Italy taxes its residents on worldwide income and everyone else only on Italian-source income. Which group you fall into is decided by a set of residence tests that look back across the whole calendar year.

Here’s a common case. Say you’re an American software developer. You work remotely for your US employer from Denver until the end of June, then fly to Milan on July 1 to start a new life. Your instinct says you were a US person until July and an Italian taxpayer after. The US side doesn’t work that way for a citizen, because you are a US taxpayer all year. The Italian side may not work that way either, as the next sections explain.

The practical result is that your move year often needs the most careful filing you will ever do. You may file a full US return with exclusions or credits, an Italian return covering more months than you lived there, and possibly a state return because your old state still claims you. Each return affects the others, which is why order and timing matter so much.

Why Italy Has No Split Year

This is the single most important fact in this guide. Italian domestic law decides tax residence for the whole tax year, all or nothing. There is no split year. You are either an Italian tax resident for the entire calendar year, January to December, or you are not one at all for that year.

Some countries let you be resident only from the date you arrive or until the date you leave. Italian domestic law has no such rule. If you meet the residence test for a year, you are resident for all of it, including the months before you arrived or after you left. If you don’t meet the test, you are a nonresident for the whole year and Italy only taxes what you earned from Italian sources.

The all-or-nothing approach is why the exact date you move matters so much. A few weeks one way or the other can change your status for the whole year. An arrival on or before 1 July can make Italy your tax home for all twelve months. An arrival in September usually means Italy doesn’t treat you as resident until the next January. When I explain this to new arrivals at our expat meetups, the room usually goes quiet and people start checking their calendars.

Who Actually Files a US Dual-Status Return

On the US side, a true dual-status return applies to non-citizens: green card holders and people who meet the US residence tests for part of a year. A US citizen never files a dual-status return. Citizens file a regular Form 1040 every year and use tools like the Foreign Earned Income Exclusion or the Foreign Tax Credit to deal with foreign taxes.

Several groups do face a genuine US dual-status year in connection with Italy:

• Green card holders who give up US residence and move to Italy partway through a year.
• Italian or other EU nationals who leave Italy and become US residents partway through a year.
• Non-citizens on US work visas who meet the US residence tests for part of the year and then relocate to Italy.

For these people the US return has two halves: a resident period and a nonresident period, with different rules for each. Put that next to Italy’s all-or-nothing residence and you can see why the transition year is a specialist job. Firms like Taxes for Expats deal with this mismatch every filing season, and it is the kind of return where professional help pays for itself.

The Italian 183-Day Test Explained

Since 2024, Italian rules say an individual is an Italian tax resident for a year only if, for the greater part of that year, at least one of several conditions applies. The greater part means 183 days, or 184 in a leap year, and part days count. Learn these conditions well, because every scenario in this guide depends on them.

The Four Hooks: Residence, Domicile, Presence, and Registry

Think of Italian residence as four hooks. If any one of them holds you for the greater part of the year, you are normally resident for the whole year.

1. Civil-law residence. This is where you habitually live in the sense used by the Italian civil code: your actual home.
2. Domicile. This means your main personal and family ties. Where your spouse lives, where your children go to school, and where your life is centred all count.
3. Physical presence. This means simply being in Italy, counted day by day, with part days included.
4. Registry enrolment. If you are enrolled in the anagrafe, the municipal population register, for the greater part of the year, there is a presumption that you are resident.

The “any one of them” part is what catches families out. Say you arrive in September, but your spouse and children moved to Florence in May so the kids could settle before school. Your own physical presence may be short, but your domicile, meaning your main family ties, may already have been in Italy for the greater part of the year. One hook can be enough.

Counting Days the Way the Agenzia Does

Part days count. The day you land at Fiumicino counts as a full day in Italy, and so does the day you fly out of Malpensa. Keep that in mind when you count close to the threshold, because a misjudged travel day can tip the result.

Here are the key numbers for counting from a fixed date to the end of a year, or from the start of a year to a departure date:

• 1 July to 31 December is 184 days. That clears the threshold in both standard and leap years.
• 1 September to 31 December is 122 days, well below the threshold.
• 1 January to 30 June is 181 days, or 182 in a leap year, which falls short of the 183 or 184 needed.
• 1 January to 31 July is 212 days in a standard year, comfortably above the threshold.

Keep a simple travel log from the day you start planning the move: boarding passes, train tickets, rental check-ins. When I started mine, I thought it was overkill. Two years later, when a question came up about a departure-year return, that spreadsheet saved me hours of reconstruction and a lot of anxiety.

The Rebuttable Registry Presumption

Registry enrolment deserves its own discussion because it creates a presumption, not a final verdict. If you are enrolled in the anagrafe for the greater part of the year, Italy presumes you are resident. That presumption is rebuttable, meaning you can challenge it with evidence that your residence, domicile, and presence were really elsewhere.

In practice you want your registry status to match reality. When you arrive, registering promptly is part of settling in properly. The steps are covered in How to Register Residency at the Italian Anagrafe. When you leave, cancelling your registration is just as important. If you forget to deregister, the presumption keeps working against you after you’ve gone.

Italian citizens who leave have an extra step: registering with AIRE, the register of Italians living abroad. If you hold Italian citizenship through descent or marriage, read The AIRE Register and Your Tax Position: What Americans Should Know before you book your flight home. The order in which you deregister and register affects how your departure year is treated.

Your permesso di soggiorno date has nothing to do with the tax test. Tax residence depends on residence, domicile, presence, and registry enrolment, not on when your residence permit was issued or when you collected it from the Questura.

Moving to Italy Mid-Year: Arrival Scenarios

This is where the rules start to matter for real people. I’ll use two arrival scenarios I’ve seen many times among friends and readers. In both, the person is a US citizen moving to Italy for the long term.

The July 1 Arrival: Surprise Whole-Year Residency

Meet Rachel. She’s a marketing consultant from Portland who signs a lease in Turin’s San Salvario neighbourhood, lands on July 1, registers with the anagrafe within weeks, and stays put. From July 1 to December 31 she spends 184 days in Italy, counting the arrival day. That is the greater part of the year, so the physical presence hook alone makes her an Italian tax resident.

Because Italy has no split year, she is resident for the whole year. Her Italian return covers worldwide income from January 1, including the six months of consulting income she earned while still living in Oregon. That surprises most people. She left the US mid-year, yet Italy treats her as if she had lived there since New Year’s Day.

She isn’t automatically taxed twice. Treaty relief and foreign tax credits exist to stop that. Under the US-Italy tax treaty and the domestic credit rules on both sides, the tax she paid on the January-to-June income can usually be credited in the right place. The mechanics are detailed, though: which country has the first right to tax which income, how credits move between returns, and in what order everything gets filed. Getting that wrong is how people end up paying twice and then spending months trying to get it back. Treaty Tie-Breaker Rules: US or Italian Tax Resident? covers the treaty logic in depth.

The September Arrival: A Clean First Year

Now meet David. He’s a retired teacher from Chicago who arrives in Lecce on September 1 and registers soon afterwards. From September 1 to December 31 is 122 days, nowhere near the greater part of the year. His spouse travels with him, so his family ties don’t create an earlier domicile in Italy. He normally does not become an Italian tax resident for his arrival year.

For that first calendar year, David is a nonresident in Italy’s eyes and would only declare Italian-source income, if he had any. His Italian tax residence normally begins on the following January 1, and from then on Italy taxes his worldwide income each year.

This is why tax-aware movers sometimes plan their arrival date. If the timing is flexible, arriving later in the year can mean your first Italian return covers a cleaner year without months of pre-move income. That doesn’t suit everyone, since jobs, school terms, and lease dates often decide for you. But if you have a choice, it is worth talking it through with a tax professional before you book.

Arrival Scenarios Side by Side

The table below summarises the main arrival and departure scenarios in this guide. It assumes each person’s residence, domicile, physical presence, and registry enrolment all line up with the dates shown.

Scenario	Days in Italy that year	Italian status for that year	What Italy taxes
Arrive 1 July and stay	184 days	Resident for the whole year	Worldwide income for all twelve months, with treaty relief
Arrive 1 September and stay	122 days	Not resident; residence normally begins the following 1 January	Italian-source income only for the arrival year
Leave 30 June, all ties end	181 days, or 182 in a leap year	Not resident for that year	Italian-source income only
Leave 31 July, all ties end	212 days	Resident for the whole year	Worldwide income for all twelve months, with treaty relief

The September row hides one condition: if any other hook, such as domicile through family already living in Italy, holds for the greater part of the year, the result can flip. The days column only tells the whole story when every hook moves on the same dates.

What the US Return Looks Like in the Arrival Year

On the US side, Rachel and David each file a normal Form 1040 for the move year, because both are US citizens. The question is which relief applies to income earned after the move.

The Foreign Earned Income Exclusion on Form 2555 has two ways to qualify. The bona fide residence test needs you to be a resident of a foreign country for an uninterrupted period covering a full tax year, which a mid-year mover can’t meet in the arrival year without waiting. The physical presence test needs a minimum number of full days outside the US within a rolling window that can straddle two calendar years. Many first-year movers qualify under physical presence, sometimes only after the following year has started, which affects when they can file. Form 2555 for Italy Residents: Bona Fide vs Physical Presence goes through both tests.

The Foreign Tax Credit on Form 1116 is the other main route. Italy’s income tax, IRPEF, tends to be substantial, so many Americans in Italy find credits work better than the exclusion, especially once they become full Italian residents. For Rachel’s whole-year-resident situation, credits are usually the main tool. Form 1116 for Italy: Turning Italian IRPEF Into a US Credit explains how they work.

Don’t forget your old state. Some states keep treating you as a resident after you leave, depending on your ties, your driver’s licence, and whether you kept a home there. State Tax Residency When You Move to Italy: Which States Keep Taxing You is worth reading before your last day in the US.

Leaving Italy Mid-Year: Departure Scenarios

Departure years run the same logic in reverse, and the stakes are similar. When I helped a friend plan her move from Rome back to Boston, the departure date we chose decided whether she would owe Italy a full year of worldwide income.

Leaving on 30 June

Meet Sofia, a British-born designer leaving Florence for a job in New York. She ends her lease, cancels her anagrafe registration, moves her belongings out, and flies on June 30. Her partner leaves with her. From January 1 to June 30 is 181 days, or 182 in a leap year, below the 183 or 184 needed.

Because her residence, domicile, physical presence, and registry enrolment all end on June 30, Sofia is normally not an Italian tax resident for that year at all. She files in Italy only for Italian-source income, for example an Italian property she still rents out or payments from an Italian employer for work done in Italy.

The “all end” condition matters. If Sofia had left her partner behind in Florence or kept her anagrafe registration “just in case”, one of the four hooks could still hold for the greater part of the year. A clean exit needs every tie cut on the same timeline. For more on wrapping up your Italian life, Leaving Italy: Shipping Your Belongings Home Without Overpaying covers the logistics side.

Leaving on 31 July

Now move Sofia’s departure to July 31, perhaps because her lease ran to the end of the month or she wanted one last summer on the Tuscan coast. From January 1 to July 31 is 212 days in a standard year, clearly the greater part of the year.

The result changes completely. Sofia is an Italian tax resident for the whole year and declares worldwide income for all twelve months, including her New York salary from August to December, with treaty relief to prevent double taxation. One extra month in Italy brought five months of American earnings onto her Italian return.

Treaty relief doesn’t make this harmless. It means coordinating US withholding, Italian assessment, and credits across two returns filed at different times in two languages. It also brings Italian foreign-asset reporting into play, because as a full-year resident her US bank accounts may need to appear in the Italian monitoring section. Quadro RW and FBAR Together: The Same Assets Reported to Two Countries explains how that overlap works.

Moving to the US: When a True Dual-Status Return Appears

Sofia is not a US citizen, so her move to New York creates a true US dual-status year. She is a US nonresident for the months before her US residence starts and a US resident afterwards. The US return combines a resident portion with a nonresident statement, each following different rules on what income is included and which deductions apply.

Depending on her circumstances, there may be elections that change this. One example is choosing to be treated as a US resident for the full year in certain cases involving a spouse who is a US citizen or resident. Each election has consequences for worldwide income and for the Italian side. If she leaves Italy late enough to be an Italian resident for the full year, the most careful planning is needed: one country may treat her as resident for the whole year while the other treats her as resident for only part of it.

Green card holders leaving the US for Italy face the mirror image. They have a dual-status year on the way out, and if they have held long-term residence, they need to check whether the US expatriation rules apply, including the exit-related forms and the possibility of being a covered expatriate. These are high-stakes rules, and they are what dedicated expat tax firms handle every day.

A Step-by-Step Filing Plan for Your Transition Year

After living through my own move year and helping friends through theirs, I think in sequences. Here’s the plan I give people over coffee at our regular bar near Piazza Santo Stefano.

Documents to Gather Before You Start

Start collecting these the moment the move becomes real, not when tax season arrives:

• Proof of your exact travel dates: boarding passes, e-tickets, passport stamps where they exist.
• Your Italian lease or property deed, and the end date of your previous home’s lease or sale.
• Your anagrafe registration and, for departures, your cancellation confirmation.
• Evidence of where your spouse and children lived and when, such as school enrolment records.
• Payslips, contractor invoices, and pension statements split by month, so income can be assigned to the right period.
• Year-end statements for every bank, brokerage, and pension account in both countries.
• Your codice fiscale and, if you have one, your SPID login for Italian online services.

Splitting income by month sounds tedious, but it is essential. In a US dual-status year, income is divided between the resident and nonresident periods. In an Italian whole-year-resident year, you need to show which income was earned where so that treaty relief and credits land correctly. Monthly records save a great deal of back-and-forth.

The Filing Sequence That Works

The order matters because each return feeds the others:

1. Settle your Italian status for the year. Count your days, check all four hooks, and decide whether you are an Italian resident for the whole year or a nonresident with only Italian-source income.
2. Settle your US status for the year. Citizens file a full-year Form 1040. Non-citizens work out whether they have a dual-status year and when their US residence starts or ends.
3. Map each income item to a country. Use the treaty to work out which country has the first right to tax each income stream and which country gives relief.
4. Choose your US relief method. Decide between the Foreign Earned Income Exclusion and the Foreign Tax Credit, or a combination, based on how much Italian tax you expect to pay.
5. Check whether you qualify under the exclusion’s day-count test yet. If you need days that fall in the next year, consider extending your US filing rather than filing early and amending later.
6. Prepare the Italian return. Decide between the Modello 730 and Redditi PF, which affects what can be reported and how. Filing Taxes in Italy: Modello 730 vs Redditi PF compares them.
7. Complete foreign asset reporting on both sides. That means FBAR and Form 8938 in the US, and the Italian monitoring section if you are an Italian resident for the year.
8. Reconcile credits. Make sure the tax credited in each country matches what was actually paid or assessed in the other, and keep records of payments and assessments.
9. File any state return your former state still requires.
10. Archive everything. Store all documents, your travel log, and copies of both returns for at least as long as either country can audit you.

For US bank reporting specifically, FBAR for Italian Bank Accounts: Who Must File and How explains what Treasury expects once your Italian accounts are open.

Pressure Points That Deserve a Second Look

Some parts of the transition year deserve a second check even if you file the rest yourself.

The first is investment income around your move date. Selling US stocks or funds just before or just after becoming an Italian resident can change which country taxes the gain, and in a whole-year-resident year Italy may reach back to gains realised before you arrived. Selling US Investments While Resident in Italy: Which Country Taxes the Gain explains the timing.

The second is Italian funds and products bought soon after arrival. Many European investment funds have unfavourable US tax treatment for Americans. Buying one with your welcome-to-Italy savings can create a reporting problem that lasts for years.

The third is your Italian accountant. Many excellent Italian commercialisti have limited experience with US returns, and many US preparers know little about the Italian system. The transition year is where those gaps show. How to Find an English-Speaking Commercialista in Italy can help you find someone on the Italian side who is comfortable working with a US counterpart.

Why Taxes for Expats Is Built for the Transition Year

I’m not shy about recommending professional help for the move year. I tried to do my own and got the order of steps wrong. A dual-status or transition year combines rules you can learn with judgement calls about timing, elections, and treaty positions that are hard to make without experience. That is why I point readers to Taxes for Expats when the move year comes around.

What a Specialist Expat Tax Firm Handles

Taxes for Expats works only with Americans and US taxpayers living abroad, so the issues in this guide are its everyday work rather than edge cases. For an Italy transition year, that typically covers:

• Deciding whether a client files a regular full-year Form 1040 as a citizen or a true dual-status return as a non-citizen.
• Comparing the Foreign Earned Income Exclusion and the Foreign Tax Credit for the client’s actual Italian tax picture, including whether to extend the US filing to qualify under the exclusion’s day-count test.
• Preparing FBAR and Form 8938 filings for newly opened Italian accounts.
• Flagging state residency exposure from the client’s former home state.
• Handling green card surrenders and the related exit filings for long-term residents.
• Catching up on missed past filings if the move year shows that earlier years were never filed properly.

Because the team sees mid-year arrivals and departures all the time, they know to ask about your exact travel dates, your family’s location, and your anagrafe status before running any numbers. Those are the questions that decide your Italian residence, and they drive everything else.

How to Work With Taxes for Expats Before and After Your Move

The best time to contact Taxes for Expats is before you book your flight, not after the year ends. A short planning conversation about your likely arrival or departure date, your income for the year, and any investment sales you’re considering can head off problems that are expensive to fix later. For some people, moving the date by a few weeks changes their Italian status for the whole year, and that is worth knowing in advance.

Once the year has ended, the workflow is simple. You upload your documents through their secure portal: income statements, travel log, account statements, and any Italian assessments. Their preparers then build the US return around your Italian position. Pricing depends on how complex your return is, such as dual-status filing, the number of foreign accounts, and how many forms are needed, so check the Taxes for Expats website for current packages and quotes before you commit.

If you’re unsure whether your situation is complex enough to need a specialist, that uncertainty usually means it is. Single-country, single-status years can be manageable alone. A year that crosses the Atlantic usually isn’t.

Pairing Your US Preparer With an Italian Commercialista

No US firm files your Italian return, and no Italian accountant files your US one. What works is two professionals who share information. When Taxes for Expats prepares your US return, they need your Italian assessment figures to calculate foreign tax credits correctly. Your commercialista needs to know what was taxed and withheld in the US to apply treaty relief on the Italian return.

My own approach is simple. I introduce the two by email early, share the travel log and income breakdown with both, and ask each one to confirm the residence position they are taking for the year before filing anything. If both returns are built on the same facts and the same residence conclusion, the credits line up and the double-taxation problem goes away.

If you are planning a move to Italy this year or leaving after a good run, start your travel log today, collect your documents as you go, and book a planning call with Taxes for Expats before your move date is fixed. Your transition year will be smoother if you plan it in advance.
