Proving where your investment money came from is a central part of most citizenship and residence-by-investment applications. You normally need to distinguish between source of wealth — how your overall wealth was accumulated — and source of funds — the origin and movement of the specific money being used for the investment. The safest approach is to build the evidence trail before transferring the funds.

As our guide to source-of-funds evidence for Hungary residence explains, a programme may require evidence showing both that the money was acquired lawfully and that the investment amount is genuinely available. Hungary’s official guest-investor guidance, for example, expressly requires applicants to credibly substantiate the legal origin of the money available for investment.

Evidence depends on how your wealth was built

Source	Common supporting evidence
Employment income	Payslips, employment contract, bank statements and tax records
Business income or sale	Company accounts, ownership records and sale agreement
Property sale	Sale contract, completion statement and bank evidence
Inheritance	Will, probate documents and estate distribution records
Investments or dividends	Brokerage statements, dividend records and tax documents
Gift or benefactor	Gift documentation plus evidence of the donor’s own source of funds

The exact requirements differ by programme. Dominica’s current document list includes 12 months of bank statements, employment or financial statements and a notarised affidavit of source of funds. Its CBI Unit describes the programme’s checks as multi-layered rather than a fixed “four-tier” system. See our Dominica citizenship by investment guide and the official Dominica required-document list.

Malta’s Permanent Residence Programme is different: Residency Malta describes its due diligence as a four-tier process and has specific documentation requirements where a benefactor provides funds. Our Malta MPRP due diligence guide covers that distinction.

Avoid gaps in the money trail

Unexplained transfers between several accounts, inconsistent dates or documents that conflict with declared income can trigger further questions. Where gifted funds are permitted, expect the donor’s finances to be examined as well.

Visa history also needs careful disclosure. Requirements differ between countries. Under Dominica’s current regulations, an applicant can be refused where they have previously been refused a visa to the UK, EU, United States, Canada or another relevant visa-free country and have not subsequently obtained the required visa or residence permission.

For Türkiye, keep documentary evidence showing how the qualifying investment was funded and transferred; our source of funds guide for Turkish citizenship by investment explains the practical trail.

Filing rules vary between programmes

Do not assume every investment programme follows the same application process. Dominica expressly requires applications to be handled by an Authorised Agent, and Saint Lucia also operates through authorised programme agents. European investor-residence routes can have different filing procedures.

A structured review of citizenship by investment due diligence should therefore happen before the money moves. A short chronology explaining when the wealth was earned, where it was held and how it reached the investment account can help keep the file understandable. Our Turkey citizenship timeline shows why sequencing matters, while a second passport solicitor can review the supporting evidence before submission.

Tax and currency records still matter

If the programme’s investment is denominated in another currency, retain bank transfer records and evidence of the exchange rate used.

A new citizenship also does not automatically change your UK tax position. The Common Reporting Standard primarily works by reference to tax residence, not citizenship, and financial institutions may be required to report accounts according to the holder’s tax residence. Tax advice should therefore be considered separately from immigration planning.

Frequently asked questions

What is the difference between source of funds and source of wealth?

Source of wealth explains how your overall wealth was accumulated. Source of funds traces the specific money being used for the investment.

Can I use gifted money?

Possibly, depending on the programme. Where gifts or benefactors are permitted, the donor will usually need to provide their own supporting financial evidence.

Do all programmes require 12 months of bank statements?

No. Dominica currently lists 12 months of bank statements, but other programmes have different documentary requirements. Always check the current rules for the specific route.

Choosing the right programme

Source-of-funds principles recur across investment migration, but the evidence and application process vary. Compare St Lucia citizenship by investment, Greece residency by investment, the Hungary Golden Visa and the Italy investor visa, or explore our global residency and citizenship programmes.

Before transferring investment funds, have your source-of-funds file reviewed so any gaps can be addressed before submission.
