Obtaining a Tax Identification Number for Foreigners in Italy: 2026 Updated Legal Guidelines for the Codice Fiscale

 How do foreigners obtain a tax identification number in Italy? This includes information on the Codice fiscale application, AA4/8 form, consular applications, Agenzia delle Entrate, Questura, Sportello Unico, real estate purchases, rentals, bank accounts, company transactions, and a comprehensive legal guide for Turkish citizens.

Entrance

In Italy, obtaining a tax identification number for foreigners is a fundamental step for almost every official, commercial, and legal transaction in the country. Known in Italian as the " codice fiscale," it's not simply a number used for tax payments. Foreigners need a codice fiscale for many things, including signing rental agreements, opening bank accounts, buying real estate, inheriting property, establishing a company, applying for residence permits, enrolling in university, accessing the healthcare system, handling billing or subscriptions, conducting notary transactions, or filing lawsuits.

According to a statement from the Italian Embassy in Ankara, the tax identification number (codice fiscale) the Agenzia delle Entrate, the Italian Revenue Administration, to identify Italian or foreign individuals in their dealings with Italian public administrations, private individuals, and legal entities. For individuals, this number is determined based on their personal information. The same statement indicates that the codice fiscale is required for transactions such as tax payments, fees, inheritance acceptance, contracts with public or private institutions, financing requests, sponsorships, and real estate rentals.

Therefore, obtaining a tax identification number in Italy is not just a matter of accounting or tax law. It is directly linked to immigration law, real estate law, banking, corporate law, inheritance law, rental law, and contract law. For Turkish citizens in particular, the codice fiscale serves as their primary legal identity key in Italy.

What is Codice Fiscale?

The Codice fiscale is a tax identification code in Italy that identifies natural persons and, in some cases, legal entities in relation to public administration and private law transactions. For natural persons, it is usually an alphanumeric code of 16 characters. This code is generated based on information such as name, surname, date of birth, gender, place of birth, and a check character.

However, there is an important point here: although a code similar to the codice fiscale can be generated using some calculation tools on the internet, the legally secure number that can be used in official transactions is the official tax number assigned by the Agenzia delle Entrate. Therefore, a foreign national should not use a code generated from the internet in a contract or banking transaction; they should obtain the official assignment document.

The Codice fiscale can be thought of as similar to the tax identification number in Türkiye, or to the function of the Turkish national identity number in some transactions. However, its use is much broader in Italy. Even if a person is not a tax resident in Italy, meaning they are not considered a full taxpayer in Italy, they may still be required to obtain a Codice fiscale to carry out certain legal transactions in Italy. For example, a Turkish citizen living in Türkiye may need to obtain a Codice fiscale to buy a house in Italy or to open an account in an Italian bank.

Does Codice Fiscale mean Tax Residency?

One of the most common mistakes is thinking that obtaining a codice fiscale automatically makes one a tax resident in Italy. This is incorrect. The codice fiscale is an identification code that allows a person to be identified in relation to Italian administration and private law transactions. Tax residency, on the other hand, is a separate status that determines in which country a person will be taxed on their income.

A Turkish citizen can obtain a codice fiscale solely for the purpose of purchasing real estate in Italy. Obtaining this number does not automatically make the individual a full taxpayer in Italy, subject to worldwide income tax. However, if the individual spends a significant portion of the year in Italy, relocates their family and life center there, registers residency in Italy, or establishes their work/residence in Italy, then tax residency may become a separate issue.

Therefore, the application for a codice fiscale should not be confused with an analysis of tax residency. The codice fiscale is a technical identification number; tax residency, on the other hand, is assessed separately based on a person's life, residence, family, economic activity, and physical presence.

For which transactions should foreigners obtain the Codice Fiscale?

The range of transactions requiring foreigners to obtain a code fiscale is very broad. The most common cases are as follows:

In Italy, anyone wishing to sign a rental agreement must use the codice fiscale as a party to the agreement. The identity and tax information of the parties is important when registering the rental agreement with the Agenzia delle Entrate.

Foreigners wishing to purchase real estate in Italy use the Codice Fiscale for notarized sales, preliminary sales agreements, land registry/cadastre records, tax payments, and banking transactions. The Italian Consulate General in Istanbul states that foreigners needing a tax identification number to purchase real estate or conduct commercial/financial activities in Italy can authorize a representative to request the number from the Revenue Administration on their behalf.

In Italy, banks typically require a passport, proof of address, proof of residence/visa status, and the codice fiscale (Italian tax code) from foreigners wishing to open a bank account. The account opening process may require additional documents depending on the bank's compliance and anti-money laundering policies.

For students who will be studying at a university in Italy, the codice fiscale (tax identification number) is important for registration, scholarships, rent, banking, and residence permit procedures. According to the Istanbul Consulate General, students who need a tax identification number for university pre-registration can automatically obtain this number UNIVERSITALY portal; for non-EU students, the process can be completed with Sportello Unico or Questura during the residence permit application.

Foreigners wishing to file a lawsuit, inherit property, conduct notarial transactions, or sign contracts in Italy may also be required to obtain a codice fiscale. The Ankara Embassy explains that foreigners needing a tax identification number to initiate legal proceedings in Italy can authorize their lawyers to obtain the codice fiscale from the Revenue Administration.

Obtaining the Codice Fiscale for Foreigners Not Residing in Italy

The method for obtaining a tax identification number (codice fiscale) for foreigners not residing in Italy may vary depending on the purpose of the transaction and the location of the application. A Turkish citizen living in Türkiye may wish to obtain a tax identification number before traveling to Italy. This is particularly relevant for transactions such as real estate purchases, bank accounts, inheritance matters, commercial contracts, or filing lawsuits.

According to the Turkish-language statement from the Italian Consulate General in Istanbul, foreign nationals who do not reside in Italy must, as a rule, authorize someone specifically to submit the tax identification number application form directly to the Italian Tax Office. The same page states that only in exceptional cases where online procedures or appointing a representative are not possible, foreigners may request a tax identification number from the competent Italian Consular office in their place of residence; in this case, the consular office will forward the request to the Italian Tax Office.

The Ankara Embassy also explains that foreigners who do not reside in Italy can authorize someone specifically to submit their tax identification number application form to the Tax Administration offices throughout Italy; in exceptional cases, the request can be made through the consular office.

Therefore, there are two practical options for Turkish citizens living in Türkiye. Firstly, they can apply to the Agenzia delle Entrate in Italy by giving specific authorization to a lawyer, consultant, real estate agent, or trusted person in Italy. Secondly, if the process depends on an online procedure or if authorizing a representative is not possible, they can apply to the competent Italian consular authority.

Obtaining the Codice Fiscale for Foreigners Residing in Italy

Foreigners who have entered Italy can obtain a codice fiscale through different institutions depending on their situation. EU citizens who plan to stay in Italy can apply to the local office of the Agenzia delle Entrate with form AA4/8 and a valid identity document. The Embassy in Ankara states that the request of EU citizens must be justified and supported by a valid passport or identity document.

For non-EU citizens, i.e., Turkish citizens, the process is different. Non-EU individuals planning to stay in Italy are issued a tax identification number (codice fiscale), in some cases along with the residence permit process. According to the Ankara Embassy, ​​for foreigners applying for a residence permit for work or family reunification purposes, the tax identification number Sportello Unico per l'Immigrazione ; for other types of residence permits, Questura, i.e., the Police Department.

This distinction is important. For example, someone coming from Türkiye through a work permit or family reunification process can obtain their tax identification number during the immigration office process. In contrast, for education, self-employment, investment, or other types of residency, the Questura process may be involved. For short-term stays or applications purely for processing purposes, the Agenzia delle Entrate office or a representative may be considered.

What is the AA4/8 form?

The most important document in a tax code application the AA4/8 form. In the official form title of the Agenzia delle Entrate, AA4/8 is defined as the form used for tax code applications, notification of changes to personal information, and duplicate requests for tax code cards or health cards.

The AA4/8 form is used for natural persons. This form includes fields such as the applicant's name, surname, gender, date of birth, place of birth, nationality, residence or overseas address, type of application, representative information, and reason for application. It is very important to fill out the form correctly. Careful attention should be paid to the order of name and surname, Turkish characters, place of birth, spelling as it appears in the passport, post-marital surname, and previous identification information.

A misspelled name, date of birth, or place of birth can later create discrepancies in banking, notary, land registry, rental agreement, or residence permit transactions. For Turkish citizens, in particular, the Italian spelling of Turkish characters such as “ğ, ü, ş, ö, ç, ı” must be consistent with the Latin characters used in the passport.

Required Documents for Application

For a foreign natural person applying for a codice fiscale, the following documents are generally required:

A valid passport or identity document. For Turkish citizens, the passport is the most basic identity document. The photocopy of the identity document must be legible, and the name, surname, date of birth, place of birth, and citizenship information on the passport must match the information on the form.

Completed and signed AA4/8 form. The form can be prepared using either the Italian or English version. If the application is to be submitted through a representative, the form must be signed by the applicant and authorization must be given to the representative.

Reason for application. The Istanbul Consulate General states that applications for a tax identification number must be submitted with the relevant form, a copy of the identity document, and the reasons for the request. Reasons may include: purchasing real estate, a lease agreement, inheritance proceedings, a bank account, university registration, filing a lawsuit, a company transaction, or any other legal action.

If the application is to be made through a representative, a special authorization or power of attorney is required. A power of attorney issued in Türkiye may require an apostille and an Italian translation to be used in Italy. However, in some simple applications, the consulate or Agenzia delle Entrate may also accept a specially formatted authorization letter. The specific practice of the office where the application is to be made should be checked.

In some cases, proof of address, residence permit, visa, university acceptance letter, pre-sale contract, notary appointment, power of attorney, or bank request letter may also be required. The process can be faster, especially if the grounds for the application are strongly documented.

Application Procedures for Turkish Citizens

For Turkish citizens, the application process varies depending on their location and the purpose for which they are requesting the codice fiscale.

Turkish citizens residing in Türkiye who wish to purchase real estate in Italy can obtain a tax identification number from the Agenzia delle Entrate in Italy by granting special authorization to their representative in Italy. Statements from the Istanbul Consulate General and the Ankara Embassy indicate that foreigners requiring a tax identification number for real estate or commercial/financial activities can appoint a representative.

Turkish students who will study in Italy can automatically obtain a tax identification number through the UNIVERSITALL portal during the pre-registration phase. Later, as non-EU students, completing the Questura or relevant immigration process may be necessary for their residence permit application.

For Turkish citizens going to Italy for work or family reunification, the tax identification number (codice fiscale) can be assigned during the Sportello Unico per l'Immigration process. The Ankara Embassy states that for foreigners applying for residence permits for work and family reunification purposes, the tax identification number will be issued by the Immigration Office located in each province.

A Turkish citizen who intends to file a lawsuit or initiate legal proceedings in Italy can authorize their Italian lawyer to obtain a tax identification number (codice fiscale) from the Italian Revenue Administration. The Turkish Embassy in Ankara explains that foreigners who need a tax identification number to initiate legal proceedings can also authorize their lawyer to provide this information.

Application for Codice Fiscale via the Consulate

Italian diplomatic missions in Türkiye may play a role in certain situations regarding the codice fiscale (tax identification number). However, in practice, direct consular application is not always the first and most common option for foreigners who do not reside in Italy. According to the Istanbul Consulate General, the possibility for foreigners to request their tax identification number from the competent Italian Consular office in their place of residence is particularly relevant in cases where online procedures or appointing a representative is not possible.

Consular applications generally require an AA4/8 form, a photocopy of the passport, a statement of reason for application, and any supporting documents. Some representations may use an appointment system, email application, or specific form formats. Therefore, the application location should be determined according to the applicant's place of residence; the current guidance of the Istanbul Consulate General or the Ankara Embassy should be checked.

The processing time for consular applications can vary. For urgent matters such as real estate purchases, notarized transfers, or bank accounts, applying through a representative in Italy (Agenzia delle Entrate) may be faster than relying solely on the consular process.

Application through a Representative or Lawyer

For foreigners not residing in Italy, the most practical method is often applying through a representative. This representative can be a lawyer, financial advisor, real estate agent, family member, company official, or a trusted person. However, the authorization to apply must be clear and documented.

The representative typically submits the applicant's signed AA4/8 form, a copy of the passport, a power of attorney, and their own identification document with the application. Reasons for application may include real estate purchase, lease agreement, inheritance, bank account, company formation, or legal proceedings.

When applying through a lawyer, it is beneficial to clearly state the powers granted in the power of attorney, such as "to apply for a tax code at the Agenzia delle Entrate, to obtain documents, to request corrections, and to obtain a tax identification number certificate." Especially if a lawsuit is to be filed in Italy or if an inheritance/real estate transaction is to be conducted, the power of attorney should be broadly drafted from the outset and tailored to the purpose of the transaction.

Code Fiscale Card and Certificate

When a tax identification code (Codice fiscale) is issued, sometimes only a tax identification number certificate is given to the individual. A physical card can also be requested. According to the Ankara Embassy's statement, those wishing to obtain a tax identification card should submit the relevant form along with a photocopy of their identity card to request a tax identification number and card; a copy can be requested using the same methods in case of loss of the paper document or plastic card.

In practice, for most transactions, presenting the correct official codice fiscale document or tax identification number may suffice instead of a physical card. However, banks, notaries, or some institutions may require an official certificate. Therefore, when applying, simply obtaining the number verbally should not be enough; an official document should be obtained.

How to fix CodeFiscale errors?

The name, surname, date of birth, place of birth, or gender information may have been entered incorrectly in the Codice fiscale application. This error can occur especially due to Turkish characters, double names and surnames, post-marital surnames, and spelling differences between passport and civil registry records.

An incorrect tax code can cause serious problems in the future. Bank accounts may not be opened, notary transactions may not be completed, rental agreement registration may be rejected, or the same person may appear in the system with different codes. Therefore, when an error is noticed, a correction should be requested by contacting the Agenzia delle Entrate. The AA4/8 form can be used not only for initial allocation but also for reporting changes in personal information and requesting documents/duplicates. The Agenzia delle Entrate's form description indicates that AA4/8 is used for tax code applications as well as for changes and requests for cards/certificates.

For Turkish citizens, the safest approach is to prepare the application form with information that exactly matches the wording in their passport. The place of birth should be written as it appears in the passport and official documents, not simply as Turkey; the province/district, country, and foreign birth codes must be carefully entered.

The Difference Between Codice Fiscale and Partita IVA

Codice fiscale and partita IVA are not the same thing. Codice fiscale is the tax identification code of an individual or, in some cases, an organization. Partita IVA, on the other hand, is the VAT number used for individuals or businesses engaged in self-employment, commercial activity, or other economic activities subject to VAT.

For a foreigner to enter into a rental agreement, buy a house, or open a bank account in Italy, the codice fiscale is usually sufficient. However, if the person will be self-employed, issuing invoices, establishing a business, or conducting regular commercial activity in Italy, a partita IVA may also be required.

Therefore, differentiation is important for Turkish investors. Someone wishing to buy a house in Italy must obtain a codice fiscale; however, if they will be providing consulting, e-commerce, restaurant, tourism activities, or professional services in Italy, the partita IVA and company/professional registration processes must be evaluated separately.

Codice Fiscale in Real Estate Purchase

For foreigners wishing to purchase real estate in Italy, the codice fiscale is a mandatory practical document. Preliminary sales agreements, notarized sales, title/cadastre registration, tax payments, bank transfers, and real estate agent contracts are all processed using this number.

Turkish citizens must obtain a tax identification number (codice fiscale) before purchasing property in Italy. Without this number, the notarization process may be delayed. The codice fiscale may even be requested from the buyer during the purchase offer or preliminary sales agreement stages. The Istanbul Consulate General clearly states that foreigners wishing to purchase real estate in Italy can obtain a tax identification number by authorizing a representative.

Obtaining a codice fiscale for real estate purchase does not automatically grant residency rights in Italy. Real estate purchases should be considered separately from residency and citizenship processes. However, tax implications such as rental income, local taxes, IMU, TARI, and capital gains from sales should be examined separately.

Codice Fiscale in the Lease Agreement

Foreigners wishing to rent a property in Italy must use the codice fiscale on their rental agreement. This number is important for registering the rental agreement, tax office procedures, bank payments, and certain municipal residency procedures.

A registered rental agreement is a strong document showing a foreigner's address and accommodation status in Italy. A rental agreement may be required for residence permits, municipal residency registration, school registration, electricity and water subscriptions, and banking transactions. Therefore, foreign tenants should obtain a codice fiscale or at least begin the application process before signing a contract.

Rental agreements that are not registered or are paid in cash are risky for both tenants and landlords. Contracts made without a code of fiscal law can lead to record-keeping and proof issues.

Opening a Bank Account: Codice Fiscale

In Italy, banks typically require a "codice fiscale" from foreigners wishing to open a bank account. The bank uses this number for customer identification, contracts, tax reporting, and account management. For Turkish citizens in particular, a bank account in Italy is necessary for transactions such as real estate purchases, rent payments, salary payments, student expenses, company capital, or inheritance funds.

However, the codice fiscale alone does not guarantee that a bank account will be opened. The bank may also request a passport, proof of address, residence/visa status, source of funds, proof of income, and tax residency declaration. For high-value transfers to Türkiye, the bank may request additional documents in accordance with anti-money laundering regulations.

Codice Fiscale in Company Formation and Commercial Activities

In Italy, a foreign individual wishing to establish a company, become a partner, or be appointed as a director requires a codice fiscale. This code is used in the company's articles of incorporation, notarial procedures, commercial register entries, bank account openings, and tax transactions, including the tax identification information of the partners or directors.

If Turkish companies are establishing subsidiaries, branches, or representative offices in Italy, they may need to obtain the codice fiscale for their individual representatives in addition to company documents. Furthermore, if regular commercial activity is to be conducted in Italy, the company's codice fiscale/partita IVA processes will also come into play.

In company transactions, representation authority is crucial. Company decisions, signature circulars, trade registry documents, activity certificates, apostilles, and Italian translations may be required for documents issued from Türkiye. Applying for a Codice fiscale is one of the first technical steps in this complex process.

Codice Fiscale in Inheritance Procedures

In Italy, foreign heirs carrying out inheritance procedures may also need to obtain a codice fiscale. Inheritance declarations, real estate transfers, bank account closures, inheritance tax payments, and notary transactions can all be processed using this number.

The statement from the Ankara Embassy indicates that a tax identification number is required for contractual or administrative procedures such as inheritance acceptance. This is particularly important for Turkish heirs. An heir residing in Türkiye may have rights to real estate or a bank account in Italy; however, they may need to obtain a codice fiscale (tax identification number) to carry out tax and registration procedures in Italy.

If inheritance proceedings are to be handled by a representative, the power of attorney must clearly state the authority to submit inheritance declarations, obtain tax identification numbers, and conduct banking and land registry transactions.

Practical Application Strategy for Turkish Citizens

If a Turkish citizen wishes to obtain a codice fiscale, they must first clarify the purpose of their application. Is it for purchasing real estate, a rental agreement, a bank account, education, a residence permit, company formation, a lawsuit, or inheritance? Incorrectly stating the reason for the application may delay the process or require additional documents.

The second step is to determine the application location. If the person is in Italy, the Agenzia delle Entrate, Questura, or Sportello Unico process can be initiated. If the person is in Turkey, the application can be made to the Agenzia delle Entrate in Italy through a representative, or in exceptional cases, a consular application can be considered.

The third step is preparing the documents. A copy of the passport, the AA4/8 form, the reason for the application, the power of attorney, and any supporting documents if required must be prepared completely.

The fourth step is verifying the name and identification information. The name, surname, date of birth, place of birth, and citizenship information as they appear in the passport must be accurately transferred to the form. Errors that may arise due to Turkish characters should be avoided.

The fifth step is to obtain the official document. After being assigned a number, one should not rely solely on verbal information; a document or certificate must be obtained, and the same number must be used in all subsequent transactions.

Most Common Mistakes

The most common mistake is mistaking a code generated online for an official number. For official transactions, the number assigned by the Agenzia delle Entrate should be used.

The second mistake is leaving the grounds for the application undocumented. The Istanbul Consulate General states that the application must be submitted with the form, identity document, and the reasons for the request.

The third mistake is assuming that a person living in Türkiye can apply directly to the consulate in every case. Statements from Italian representations in Türkiye indicate that for foreigners not residing in Italy, applying through a representative (Agenzia delle Entrate) is a significant method; the consular route is only relevant online or in exceptional circumstances.

The fourth mistake is confusing the codice fiscale with a residence permit. Obtaining a tax identification number does not grant the right to stay in Italy. A residence permit is a separate immigration law process.

The fifth mistake is confusing the codice fiscale with the partita IVA. Obtaining a personal tax number does not mean that one has obtained a VAT number for business activity.

The sixth mistake is writing the name on the application form differently than it appears on the passport. This error can cause serious problems with banking, notary, land registry, and residency permit processes.

The seventh mistake is failing to explicitly state the authority to obtain the codice fiscale in the power of attorney given to the representative. This authority should be clearly defined, especially if dealing with a lawyer or real estate agent.

Conclusion

In Italy, obtaining a tax identification number for foreigners is the first step in many legal, financial, and administrative transactions. The Codice fiscale (tax identification number) may be required for rental agreements, bank accounts, real estate purchases, inheritance proceedings, company formation, university registration, residency applications, and litigation. As the Turkish Embassy in Ankara has stated, this number is used for identification purposes in dealings with Italian public administrations, private individuals, and legal entities.

For Turkish citizens, the application method should be determined according to whether the person is in Italy and the purpose of the transaction. Individuals who do not reside in Italy and need a tax identification number for real estate purchases or commercial/financial transactions can authorize their representatives in Italy to apply through the Agenzia delle Entrate. The Istanbul Consulate General and the Ankara Embassy clearly state this method.

For non-EU citizens going to Italy for work or family reunification, the codice fiscale can be obtained through the Sportello Unico per l'Immigrazione process; for other types of residence permits, it can be obtained through the Questura process. EU citizens and those holding certain short-term/special permits can apply to the Agenzia delle Entrate with form AA4/8.

The most important document in the application is the AA4/8 form. This is the official form used for tax code applications, changes to personal information, and card/certificate requests. The form must be completed correctly, match passport information, and clearly state the reason for the application.

In conclusion, while obtaining a tax identification number in Italy may seem like a simple administrative process, incorrect application procedures, incomplete authorization, misspelled names, or undocumented justifications can delay all subsequent processes. The safest approach for Turkish citizens is to first determine the purpose of the transaction, choose the correct application method, carefully complete the AA4/8 form, clearly specify the power of representation, and consistently use the assigned codice fiscale document in official transactions. A correctly obtained codice fiscale ensures the secure progress of real estate, banking, rental, inheritance, company, and residency processes in Italy.
