The investment value isn't the only cost you'll encounter when applying for Maltese citizenship. The administration fee is €1,000 (£860) for each applicant, excluding taxes, and there is an ongoing five-year due diligence monitoring process. Due diligence fees depend on the number of dependents on the application, charged at: • €15,000 (£12,875) for the first applicant. • €10,000 (£8,600) for each dependent. It's also vital to budget for taxes levied on rental income, where applicable, and legal fees when purchasing a property or making a long-term investment.
