Source of Funds Requirements for Golden Visa Applications: How Investors Are Asked to Prove the Money

For residence-by-investment applicants, proving that the investment money exists is only half the exercise. The other half is proving where it came from, how long it has been held, and that it is genuinely at the applicant’s disposal. Golden visa authorities ask three questions — ownership, availability and lawful origin — and the documents they accept reflect those differences. This page sets out the published source-of-funds rules for the Italian, Portuguese and Maltese programmes, with official sources cited, so applicants and advisers can compare the requirements directly.

The Three Questions Behind Every Source-of-Funds Check

Italy’s Ministry of Enterprises and Made in Italy publishes the clearest statement of the underlying questions. Its Investor Visa for Italy policy guidance, dated 19 July 2021, requires the applicant to submit documentation proving:

ownership of the financial resources allocated to the investment or donation;
that the resources are in the applicant’s complete personal availability, are transferable to Italy, and have a legal provenance;
the absence of criminal convictions and pending charges.

Portugal’s AIMA frames the same problem through the transfer: the proof is a declaration by a credit institution attesting that the required amount was effectively transferred. Malta’s Permanent Residence Programme Regulations approach it through a fit-and-proper test built on know-your-customer due diligence. The three models are not interchangeable; a document that satisfies one authority may not satisfy another.

Ownership: Bank Statements and Financial Instruments

Funds Held in a Bank Account

Where the funds are held in a bank account, Italy’s guidance requires a copy of the bank statement of account, including all operations carried out in the three months before the application. The statement must be issued not earlier than 30 days before submission, and must show:

the name of the holder;
the account number;
the identification details of the credit institution;
the amount of financial resources available in the original currency.

Funds Held as Financial Instruments

Where the funds are kept in financial instruments, the applicant submits documentation listing and describing the instruments held or acquired in the three months before the application date. A portfolio issued by a credit institution, investment fund or similar body may serve this purpose. Italy adds an eligibility test: only investments that can be converted immediately into liquid financial resources count as proof.

What Does Not Count as Proof

Italy’s guidance is explicit about what does not work. Possession of real estate, or a financial involvement in companies not limited by shares, will not be considered proof of the availability of the minimum financial resources, even in the presence of a promise of sale. In practice, an applicant cannot point to a property that will be sold later, or to a stake in an unlimited-liability company, to demonstrate that the investment funds are available.

Availability and Lawful Origin: The Credit-Institution Letter

Beyond the bank statement, Italy requires an official letter signed by an authorised representative of the financial institution where the funds are deposited (Annex C of the policy guidance). The letter must declare:

confirmation that the bank account and/or financial instruments are owned by the applicant;
the exact sum held, in the original currency and in euros, at the exchange rate applied at the time of signing;
for securities or shares, the purchase date and, if applicable, the validity period;
information on the origin of the funds;
a declaration that the sum is entirely transferable to Italy.

All submitted documents must be in Italian or English. Where an original is in another language, a certified translation must be provided.

Holding Periods and the Three-Month Rule

The central time requirement in Italy’s guidance is the three-month holding period. Where the resources have been deposited or invested in the applicant’s name for the entire three months before the application, the credit-institution declaration is considered sufficient proof of the origin of the funds. Where the holding period does not fully cover those three months, further documentation demonstrating the legal provenance of the funds must be attached.

These requirements apply at the application stage. Italy’s Investor Visa portal notes that proof of the investment itself is assessed after arrival, and the entirety of the investment must take place within three months of arrival.

Portugal’s published rules take a different approach. AIMA requires a declaration by a credit institution authorised or registered with the Banco de Portugal, attesting the effective transfer of an amount equal to or above the legally required minimum. Portugal’s pages do not state a look-back window; the decisive fact is the attested transfer itself.

When Recent Funds Trigger Extra Evidence

Where funds have been held for less than three months, Italy’s guidance says the further documentation must vary according to the nature of the financial source — a donation, sale of assets, revenues from economic activities, a will, divorce, or winnings — but in every case it must indicate the date of the transaction, the amount, the provenance and the recipient (Annex D).

The documents must also be accompanied by a report from an independent third-party expert in law or accounting, certifying the truthfulness of the information provided (Annex D.1). This is a distinct layer of evidence on top of the bank’s own declaration. Italy’s process also provides a 30-day window to respond to requests for supplementary information.

How Portugal Proves the Transfer

For all investment routes under Article 90.º-A of Portugal’s residence-permit regime, the central evidence is the declaration by a credit institution authorised or registered with the Banco de Portugal, attesting the effective transfer of an amount equal to or above the legally required amount.

For the fund investment route, AIMA adds a further condition: the investment must be the result of an international transfer of capital. The bank declaration must therefore confirm not only the amount but the cross-border character of the funds.

The scientific research route uses a second, entity-side attestation. A declaration issued by a public or private scientific research institution must attest the effective transfer of capital applied to research activities, in an amount equal to or above 500 thousand euros, or 400 thousand euros in low-density territory in NUTS III.

At the renewal stage, Portugal’s FAQ adds that an investor who does not receive income in Portugal may evidence means of subsistence through documents relating to foreign income, pensions, financial investments, bank statements or other evidence of sufficient available funds.

Malta: Due Diligence and the Fit-and-Proper Test

Malta’s Permanent Residence Programme Regulations (S.L. 217.26) embed the source-of-funds check in a wider due-diligence exercise. The regulations require evidence, on a know-your-customer basis, through due-diligence processes carried out by the agent, that there is no a priori evidence that the main applicant and his or her dependants are not fit and proper persons.

The application must also include a conduct certificate, in original format, for the main applicant and for any dependant older than fourteen at the time of application. Each dependant is separately vetted: the regulations require a successful due-diligence check in respect of each dependant.

The AML/FATF Layer

A significant part of the evidentiary burden falls on the financial institution. Under Italy’s policy guidance, the credit institution that signs the letter must declare that it acts in compliance with the FATF international standards on anti-money laundering and anti-terrorism, and that it has carried out adequate checks on the client under those standards, with particular regard to the FATF Recommendations on financial institution secrecy laws (No. 9), customer due diligence (No. 10), record keeping (No. 11), politically exposed persons (No. 12), wire transfers (No. 16), reliance on third parties (No. 17), higher-risk countries (No. 19), reporting of suspicious transactions (No. 20), and transparency and beneficial ownership of legal persons (No. 24) and legal arrangements (No. 25).

Common Reasons Source-of-Funds Evidence Fails

Two failure points recur across the published rules. The first is recent crediting. Under Italy’s guidance, funds that have not sat in the applicant’s account for the full three months trigger the additional provenance documentation and the independent expert report. An applicant who moves money shortly before applying must reconstruct the entire trail — date, amount, provenance and recipient — for the original transaction.

The second is an incomplete account of the money’s origin. Italy requires the resources to be in the applicant’s complete personal availability and entirely transferable to Italy; the credit-institution letter must state the origin of the funds. Malta’s due-diligence test examines whether the applicant is fit and proper on a know-your-customer basis. Where funds have been borrowed, received from a third party, or are otherwise not fully at the applicant’s disposal, the documentation must still account for the source of the money. An application that presents funds without explaining their origin, or that relies on excluded assets such as real estate, is exposed to requests for further evidence.

Frequently Asked Questions

What exactly do I have to prove about my investment money?

Three things, in Italy’s formulation: that you own the resources, that they are in your complete personal availability and transferable to the destination country, and that their provenance is legal. Portugal’s model concentrates the proof in a bank declaration attesting the effective transfer. Malta’s model examines whether the applicant is fit and proper through due diligence.

How far back do the bank statements have to go?

Italy requires a bank statement covering all operations in the three months before the application, issued no earlier than 30 days before submission. If the funds have been held for less than three months, additional provenance documentation and an independent expert report are required. Portugal’s published pages do not state a look-back period; the decisive document is the declaration attesting the effective transfer.

Does real estate count as proof of available funds?

Not under Italy’s rules. Real estate, and financial involvement in companies not limited by shares, are not considered proof of the availability of the minimum financial resources, even with a promise of sale. Investments must be convertible immediately into liquid financial resources.

What happens if my money was only recently deposited into my account?

Under Italy’s guidance, you must attach further documentation demonstrating the legal provenance of the funds. That documentation must indicate the date of the transaction, the amount, the provenance and the recipient, and must be accompanied by a report from an independent expert in law or accounting certifying the truthfulness of the information.

What is a credit-institution letter?

It is an official letter, signed by an authorised representative of the financial institution where the funds are held, which Italy requires as part of the proof of availability and lawful origin. It must confirm ownership, state the exact sum held in the original currency and euros, give the purchase date of any securities or shares, provide information on the origin of the funds, and declare that the sum is entirely transferable to Italy.

Are my family members checked as part of the source-of-funds process?

In Malta’s programme, each dependant is subject to a successful due-diligence check, and a conduct certificate is required for the main applicant and any dependant older than fourteen. Italy’s guidance requires the applicant to show the absence of criminal convictions and pending charges. The treatment of dependants varies by programme.

Do all golden visa programmes apply the same source-of-funds rules?

No. This article covers the published rules for Italy, Portugal and Malta, and they differ in structure and evidence. The requirements of other residence-by-investment programmes should be checked against each programme’s own official publications.
