What is a TIN?
A Tax Identification Number (TIN) is a unique identifier issued by tax authorities in your country of residence. It is used internationally to ensure tax transparency and compliance with regulations such as the EU Anti-Money Laundering Directive (AMLD) and the OECD Common Reporting Standard (CRS).
Why do we need it?
Blackcat is legally required to collect your TIN as part of customer due diligence (CDD) and reporting obligations.
It allows us to verify your tax residency.
It ensures compliance with international agreements on preventing tax evasion.
It is a standard requirement for financial institutions across the European Union.
Without providing a valid TIN, your account may eventually face restrictions.
When do you need to provide it?
You can submit your TIN at the moment of registration.
If you don’t have a TIN yet, you can still open your account, but you must provide it within 30 days of registration.
This flexibility ensures that you can start using your account right away while arranging your TIN if needed.
Country specifics
In most countries, the TIN is issued automatically once you become a tax resident.
It may appear on your national ID, residence permit, or tax certificate.
In some jurisdictions, it is called differently (e.g. NIF in Spain, Codice Fiscale in Italy, NINO in the UK).
Important notes
You must provide your TIN from the country where you are a resident for tax purposes.
If you are tax resident in multiple countries, you may be asked to provide TINs from each jurisdiction.
Submitting a false or outdated TIN may lead to account suspension due to regulatory non-compliance.
