Becoming resident in Italy after you buy: the tax switch

Register as resident in Trieste, live there, and from the first tax year you spend mostly in Italy (183 days in 2027) Italy taxes your income worldwide. It also charges 1.06% a year on property you keep abroad and 0.2% on foreign investments.

The flat you live in, meanwhile, stops paying ILIA. Residence works like a switch: some taxes go off, others come on.

In short

• Residence is a registration and a fact. You declare it to the Comune within 20 days of moving in; the Comune checks you live there.
• Tax residence follows most of the year. Since 2024, physical presence alone can be enough: 183 days in Italy (184 in a leap year), any part of a day counted (article 2 of the income tax code, TUIR).
• What you hold abroad becomes taxable. IRPEF on worldwide income at 23%, 33% and 43%; IVIE at 1.06% on foreign property; IVAFE at 0.2% on investments, €34.20 per account.
• The Trieste home goes quiet. As your main home it pays no ILIA, unless it falls in a luxury category: A/1, A/8, A/9.
• The 2% rate has a deadline. Bought as a prima casa? Move within 18 months of the deed, or repay the saving with interest and a 30% penalty.

How do I become resident in Trieste?

You file a residence declaration (dichiarazione di residenza) with the Comune's registry office, the Anagrafe, within 20 days of moving in. It is registered within two working days and takes effect from the date you filed (decree-law 5 of 2012, article 5).

Within 45 days the Comune checks that you live there, through the municipal police or other authorised staff. Silence means your declaration stands; a failed check cancels it back to the day you filed (Presidential Decree 223 of 1989, articles 18-bis and 19).

EU citizens must register after three months here, showing work, or enough resources and health cover (Legislative Decree 30 of 2007, articles 7 and 9). Enough means at least the annual social allowance (assegno sociale): €7,101.12 in 2026, plus half that sum per family member.

If you are not working, Trieste's checklist asks for a self-declaration of resources and either health insurance valid for at least a year or a European entitlement form from home. The declaration can be emailed as a signed scan.

Non-EU citizens need, as a rule, a valid permit to stay (permesso di soggiorno) first. If you live on a pension or investments, that usually means the elective residence visa (residenza elettiva), outlined in who can buy in Italy.

A foreign-plated car you own must be registered in Italy within three months of becoming resident (Highway Code, article 93-bis).

When does Italy start treating me as a tax resident?

From the tax year in which, for most of it, you have your residence or domicile in Italy, or are simply present here (TUIR, article 2, rewritten from 2024 by Legislative Decree 209 of 2023). Domicile now means where your personal and family relationships mainly unfold.

The revenue agency (Agenzia delle Entrate) reads most of the year as 183 days, or 184 in a leap year, and counts an hour on Italian soil as a day, holidays included (circular 20/E of 2024).

Italian law looks at the whole year. Arrive on 1 March 2027 and you spend 306 days here: resident for all of 2027. Arrive on 1 August and you have 153: resident from 2028, unless another test catches you.

Registration at the Anagrafe for most of the year makes you presumed resident. Since 2024 you can rebut it, but only by showing you had neither residence, nor domicile, nor presence in Italy for most of the year.

If your old country also claims you, the treaty decides. In the Italy–Germany treaty (article 4) the tie-breakers run: permanent home, centre of vital interests, habitual abode, nationality.

Italy's treaties with Germany, Switzerland and Panama also split the year of a move: liability in the old country ends the day you move and starts in the new one the next day (Italy–Germany protocol, point 3).

From 2027 the same words move into article 2 of the new income tax code (Legislative Decree 117 of 2026).

What changes in my taxes once I am resident?

Residents are taxed on all their income, wherever it arises; a non-resident only on what is earned in Italy (TUIR, article 3).

	Non-resident owner	Resident in Trieste
ILIA on the Trieste home	1.06%, or 0.70% with the regional notice	None, bar the luxury categories (A/1, A/8, A/9)
IRPEF	Italian income only	Worldwide income
RW section of the tax return	Not required	Yes, for assets abroad
IVIE on property abroad	No	1.06% of its value
IVAFE on accounts and investments abroad	No	€34.20 per account; 0.2% on investments
2% prima casa rate	With a promise to move within 18 months (some exceptions)	Yes, if the other conditions are met

IRPEF in 2026 takes 23% of taxable income to €28,000, 33% of the slice from there to €50,000 and 43% beyond (TUIR, article 11; the 2027 code keeps the bands).

Friuli Venezia Giulia adds 0.70% on taxable income up to €15,000, otherwise 1.23% on all of it. Trieste adds 0.8%, incomes up to €12,500 exempt: the same rates since 2015, kept for 2026–2028 in the city's budget.

The RW section lists property, accounts and investments held abroad (decree-law 167 of 1990, article 4). Omissions cost 3% to 15% of the amounts not declared.

IVIE is 1.06% of the value of property abroad, by months and share owned, and nothing if the total is €200 or less. For EU property the value is the cadastral value used for that country's own taxes; failing that, the cost on the deed, or market value.

Property taxes paid abroad on it are deducted (decree-law 201 of 2011, article 19).

IVAFE is 0.2% a year of the market value of foreign investments at 31 December, plus €34.20 per current or savings account, unless the average balance at that bank is €5,000 or less. Both taxes follow IRPEF's payment dates.

ILIA in detail, with the regional notice, is in owning in Trieste, year after year; what a non-resident owner files instead, in after the deed.

What if I bought with the 2% prima casa rate?

The move is then a promise with a date. The 2% rate needs, as a rule, the home to be in the comune where you live, or where you establish residence within 18 months of buying, and the promise must be in the deed (Presidential Decree 131 of 1986, tariff, part I, article 1, note II-bis).

The move counts from the day you file the declaration, not from the check. Miss the 18 months and the relief goes: the tax you saved comes back, with interest and a 30% penalty on it.

There is an exit. Before the deadline, ask the Agenzia delle Entrate office where the deed was registered to revoke your declaration: you pay the difference and interest from the date of the deed, without penalty (resolution 105/E of 2011). After it, reduced penalties (ravvedimento operoso) remain open until a notice reaches you.

Example. Suppose the 2% saved you €8,000 against the 9% rate. Revoke in time: €8,000 plus interest. Let the 18 months lapse: €8,000 plus a €2,400 penalty, €10,400 before interest. The rates are explained in purchase taxes in Italy.

A worked example: a German retiree moves to Trieste

Example. Assumptions: a retired German citizen moves from Munich into her Trieste flat, cadastral income (rendita) €1,000. She keeps her Munich flat, lent free to her son, a German current account averaging €20,000 and securities worth €150,000 at 31 December. The Munich flat's IVIE value: €300,000 (her commercialista confirms it).

A full resident year, in euros:

• ILIA on Trieste, before: 1,000 × 1.05 × 160 = 168,000; × 1.06% = €1,780.80. After: €0, as her main home.
• IVIE on Munich: 300,000 × 1.06% = €3,180.
• IVAFE: €34.20 for the account, plus 150,000 × 0.2% = €300: €334.20.
• New annual total: 3,180 + 334.20 = €3,514.20. Less the ILIA she no longer pays: €1,733.40 more a year, before credit for taxes paid in Germany on the flat.

Her pension follows the treaty, not the move. A German statutory pension (gesetzliche Rente) paid to a German citizen who is not also Italian can be taxed only in Germany (Italy–Germany treaty, article 19(4)); a company pension only in Italy (article 18). Amounts assumed; rates and rules real.

Are there tax breaks for people moving to Italy?

Two, with conditions. A third does not reach Trieste.

• Workers (impatriati). Employment and self-employment income produced in Italy counts for half, on up to €600,000 a year, or 40% if you move with a child under 18. Conditions: no Italian tax residence in the previous three years, high qualifications, work mostly in Italy, and four years' stay (Legislative Decree 209 of 2023, article 5).
• The flat tax for new residents. €300,000 a year replaces IRPEF on foreign income, plus €50,000 per family member, for moves from 1 January 2026. It needs nine of the last ten years abroad and a favourable ruling, lasts at most 15 years, and exempts you from the RW section, IVIE and IVAFE (TUIR, article 24-bis).
• The 7% on foreign pensions (TUIR, article 24-ter). Not in Trieste: see the questions below.

What to do now

• Before moving, list what you hold abroad for the RW section: property, accounts, securities, voluntary pension plans.
• Count your days: 183 in Italy (184 in a leap year), part-days included, make you resident for the whole year.
• Bought at 2%? Note the date 18 months after the deed; file the declaration, or the revocation, before it.
• Ask your commercialista which treaty article covers each of your pensions.

Frequently asked questions

Do I become tax resident in Italy after 183 days?

Under Italian law, yes: presence for most of the year is enough on its own. If your home country also claims you, the treaty decides.

Can I register in Trieste just to keep the 2% rate?

Not without living there. The Comune checks that the address is your habitual home, and a failed check cancels the registration from the day you filed. Registration for most of a year also makes you presumed tax resident in Italy.

Is the 7% pensioner flat tax available in Trieste?

No. It is limited to towns of up to 30,000 inhabitants in Abruzzo, Basilicata, Calabria, Campania, Molise, Puglia, Sardinia and Sicily, and in listed earthquake areas. None of those regions is Friuli Venezia Giulia, and Trieste, with 198,388 residents in the 2024 census, is far above the cap.

Do I pay Italian tax on a house I keep abroad?

Yes, once resident: IVIE at 1.06% of its value, less the property tax paid there. If you rent it out, the rent joins your Italian income.

Where this guide stops

It does not calculate your IRPEF, German tax or the part-year IVIE of the move; it leaves out inheritance, companies and other treaties. Whether and when to move, you decide with your commercialista.

If you own in Trieste and are weighing the move, our Own service looks after the house while you are away, and our network can introduce the right commercialista for your Italian returns: see how. If you would rather sell than move, request a confidential valuation: we sell English-first, with German-speaking support, even from afar.
