This screen is mandatory for:
- Digital Banking & Cards products for all customer types (B2C, B2B, and Freelancers) in all countries.
You must now determine whether the customer wishing to open a bank account with Solaris is subject to US tax law. Solaris is required to perform this check to comply with the Foreign Account Tax Compliance Act (FATCA). At this stage, you must ask for a self-declaration of FATCA relevance. You must ask the following question to the potential account holder and provide an accompanying yes/no input field.
- If the customer answers "yes," set the value of
fatca_relevanttotrue. In this case, the customer cannot be onboarded. - If the customer answers "no," set the value offatca_relevanttofalseand store this in your solution. - Record the timestamp of the customer's confirmation of the FATCA relevance and pass it to our API in the attribute
fatca_crs_confirmed_at(A property in the create person resource).
- Only customers with a
fatca_relevantvalue offalsecan proceed with onboarding. - For business customers, you must also collect the FATCA self-declaration from all natural persons associated with the business, such as legal representatives, beneficial owners, and any authorized person on the business account.
Are you a U.S. citizen (incl. dual citizenship), do you have a residence or a permanent residence permit in the USA, or do you reside in the USA; for more than 180 days a year?

Display the following legal text to collect the FATCA indication for the business itself (i.e., the legal entity).
In the context of a B2B bank account, the account holder is the business itself, the legal entity.
Is the business established in the USA* or has it been established under the laws of the USA*, and does the business have a tax residency in the USA*?
* Includes the US Minor Outlying Islands and the US Virgin Islands
Display the following legal text to collect the FATCA indication for all legal representatives linked to the business:
Is any of the business's legal representatives a U.S. citizen (incl. dual citizenship), do they hold a residence or a permanent residence permit in the USA*, or do they reside in the USA*; for more than 180 days a year?
* Includes the US Minor Outlying Islands and the US Virgin Islands

To comply with the Foreign Account Tax Compliance Act (FATCA), Solaris is required to perform checks to determine whether the customer is subject to US tax law. These checks are in addition to the self-declaration during the Legal and Compliance screen.
To perform the FATCA checks, parse the person and identification resources using the following endpoints:
To determine the customer's FATCA relevance, you must screen for the following hard criteria:
- Has the customer provided a US passport as their identification document? Check the
legitimation_countryattribute on the identification resource. - Is the customer a citizen of the US? Check the
nationalityattribute. - Has the customer provided a residential address in the US, the US Minor Outlying Islands, or the US Virgin Islands? Check the
countryattribute. - Was the customer born in the US, the US Minor Outlying Islands, or the US Virgin Islands? Check the
birth_countryattribute.
When to reject the customer
If any of these hard criteria attributes have the value of US or USA, you must deny banking services to the customer and stop the onboarding process. Failure to screen for these hard FATCA criteria may cause ongoing operational burdens for Solaris customer support.
To further determine the customer's FATCA relevance, screen for the following soft criteria:
- Has the customer provided a US mobile number? Check the
mobile_numberattribute. US mobile numbers have a country code of +1. - Is the customer's only address a PO box or a c/o address? Check the
address_line_1andaddress_line_2attributes.
When to reject the customer
- If the answer is "Yes" to any of the soft criteria, ask the customer to clarify their phone number and/or address.
- If the customer provides a non-US phone number and a physical address, you may onboard them.
- If the customer does not provide a non-US phone number and a physical address, you may not onboard them.
Failure to screen for soft FATCA criteria may cause ongoing operational burdens for Solaris customer support.
Note that Solaris periodically checks FATCA relevance for existing customers. If a customer's FATCA relevance changes to true, Solaris's Customer Support team will provide further instructions.
