Know Your Customer is a critical component of the financial regulatory framework in the United States with the purpose of ensuring the integrity of the financial system and combating illicit activities such as money laundering, terrorist financing, and fraud. Businesses that operate in the financial and legal sectors must implement robust KYC measures in order to safeguard against financial crimes, foster trust and transparency.
In this guide, we will explore the importance of KYC, the applicable legal framework, industries required to comply and the essential components within the U.S., the applicable legal framework, industries required to comply, and the essential components of a KYC program.
What Is KYC (Know Your Customer) and Why Is It Important in the U.S.?
At its core, KYC refers to the process that businesses, particularly those in financial sectors, undertake to verify the identity of their customers in order to ensure that customers are who they claim to be, prevent financial systems from being abused for illegal activities and comply with legal and regulatory obligations.
KYC is of vital importance in maintaining the security of the U.S. financial system. It has an important role in creating a barrier against financial crimes. This is done by requiring organizations to validate the identities of their customers as well as monitor transaction behaviors. It also forms an integral component of Anti-Money Laundering (AML) efforts.
Tied to Regulatory Mandates
The Bank Secrecy Act (BSA) and the USA PATRIOT Act place obligations on financial institutions to establish and maintain effective customer identification and monitoring protocols.
What Are the U.S. Laws and Regulations That Govern KYC?
Here, we have outlined the significance and the effects of the several key legislative frameworks of KYC compliance in the U.S.
What Is the Bank Secrecy Act (1970)?
The Bank Secrecy Act entered the history books as one of the first significant legislation aimed at combating money laundering in the United States. It imposed establishing anti-money laundering programs, maintaining records, and filing reports on transactions that exceed certain thresholds as mandatory requirements on financial institutions but we must also mention that KYC was a mandated component of these AML programs.
How Does the USA PATRIOT Act Affect KYC Obligations?
The USA PATRIOT Act was implemented in the wake of the September 11, 2001, attacks and subsequently expanded the scope of KYC requirements by mandating financial institutions to establish a Customer Identification Program (CIP) as part of their broader AML efforts. When looking at its content, verification of the identity of customers, conduct of due diligence on account holders, and identification/reporting of suspicious activities can be identified.
What Changes Did the AMLA 2020 Introduce for KYC?
To outline what reforms the Anti-Money Laundering Act introduced to the U.S. financial crime compliance framework, we can list the Beneficial Ownership Information (BOI) database, strengthened penalties for non-compliance, and expanded reporting obligations for industries beyond traditional financial institutions.
Which Entities Must Implement KYC in the United States?
Banks and Credit Unions
Traditional financial institutions have decades of experience and strict regulatory oversight, which makes them the backbone of KYC enforcement. The comprehensive customer verification procedures of these institutions continue to set the standard for other industries.
Money Services Businesses (MSBs)
These businesses are at the forefront of high-value and cross-border transactions, and about 28% of violations in KYC occur in the MSB sector (FinCEN’s 2023 report). The pressure to adopt advanced KYC tools (automated monitoring, AI-driven verification systems) is mounting on MSBs for two reasons. First, because of the high volume of transactions, and secondly, the global nature of their operations.
Fintechs and Crypto Exchanges
These innovative financial services providers face unique challenges. While trying to find the balance between streamlined customer onboarding and rigorous KYC protocols is one example of this, the heightened scrutiny and the anonymity associated with digital currencies are another.
Securities and Investment Firms
Investment brokers, asset managers, and securities firms must protect against fraud and ensure adherence to AML requirements when dealing with high-value clients and transactions. These institutions often face attempts at the final stages of money laundering, called layering and integration. As a result, they are increasingly leveraging sophisticated risk assessment tools that monitor the nature, origin, and destination in addition to the clients.
Real Estate and Legal Professionals
Real estate transactions can unintentionally facilitate money laundering if KYC measures are ignored due to the fact that high-value property sales often provide opportunities for criminals to integrate illicit funds into the legitimate economy. Luckily, real estate professionals are starting to adopt stricter due diligence measures, such as verifying clients' source of funds and identifying ultimate beneficial ownership, as well as legal professionals are starting to undertake financial activities, such as managing trusts or client accounts.
What Are the Core Components of a U.S. KYC Program?
A robust KYC program is built on several integral components, and we will explore these components by starting with CIP.
What Is a Customer Identification Program (CIP)?
This program establishes the minimum standards regarding the verification of a customer's identity through documentary evidence like government-issued ID, or non-documentary methods like credit bureau checks, in order to collect information such as full legal name, date of birth, residential address, and Social Security Number or Taxpayer Identification Number.
What Is Customer Due Diligence (CDD)?
CDD ensures that institutions understand their customers' risk profile through the verification of the customer's identity, assessment of the purpose and intended nature of the relationship, and monitoring ongoing activities to ensure consistency with expected behaviors.
When Is Enhanced Due Diligence (EDD) Required?
It is required in case higher-risk customers show up, such as politically exposed persons (PEPs) or accounts involving complex ownership structures.
What Is Ongoing Monitoring and Why Is It Crucial?
Conduction of KYC needs to be done continuously, not just once, in order to ensure that flagged behaviors like unusual transaction patterns are identified and addressed promptly.
How Does the U.S. Customer Identification Program (CIP) Work?
Institutions must collect and verify specific identity details for every customer, including their name, date of birth, physical address, and identification number. The government-issued IDs are the traditional preference, but non-documentary methods, such as database verification, have grown in popularity due to advancements in digital KYC solutions. Also, CIPs often require institutions to maintain identity verification records for five years post-customer relationship termination. Additionally, institutions must notify customers about the purpose and use of their verification details.
How Are Individuals and Entities Verified Under KYC Rules?
Individual vs. Corporate Customers
Individual customer verification typically involves straightforward documentary checks. For corporate clients, institutions must identify Ultimate Beneficial Owners (UBOs)—an often challenging process when dealing with layered ownership structures.
UBO Identification and the BOI Rule 2024
The BOI rule under AMLA 2020, effective 2024, mandates detailed reporting of beneficial ownership. Institutions will have more explicit guidelines to identify and verify UBOs, ensuring greater oversight.
What Are the Red Flags in KYC Processes?
Mismatch between documents and client behavior, use of nominee shareholders or shell entities, clients from high-risk jurisdictions, and refusal to provide information or beneficial ownership are some of the common red flags in KYC processes.
What Is Required for Beneficial Ownership Disclosure in the U.S.?
The disclosure of beneficial ownership information for certain entities and detailed information reports about individuals who have significant ownership or control of certain businesses are required for most corporations, LLCs, and similar entities, but certain entities like publicly traded companies or heavily regulated industries, may be exempt.
What Are the Penalties for Failing to Comply with KYC Regulations?
Should compliance not be achieved, businesses have a high chance of facing civil penalties that range from $500 to $25,000 per day of non-compliance or even criminal charges in more serious cases.
How Can Businesses Build a Compliant KYC Framework?
- First, develop a clear and detailed onboarding process for the verification of customer identities, through gathering and verifying personal information, conducting risk assessments, and ensuring all documentation meets compliance standards.
- Also, you are encouraged to invest in reliable KYC software solutions because they do tremendous help in streamlining identity verification, automating processes, and reducing manual errors.
- You must also consider regularly training employees on KYC regulations and best practices in order to establish strong internal controls across the organization.
- Last but not least, conduct independent audits and regular testing of your KYC process. Then identify gaps or weaknesses, and finally use the insights from these reviews to continuously improve and stay ahead of regulatory changes.
What Are the Most Common KYC Mistakes U.S. Businesses Make?
- Firstly, many businesses fail to update their KYC document templates, and this leads to compliance gaps, a slow onboarding process, increased risk of errors or missing critical information required by regulators.
- Another one is that risk assessments should be a dynamic process, so businesses that neglect to review and update these assessments miss the chance to identify and address new risks, which leaves them vulnerable to fraud or regulatory issues.
- Lastly, we can mention that a customer's risk profile can change over time, and businesses that don’t actively monitor shifts in ownership, transaction patterns, or behaviors may overlook potential red flags.
How Does KYC Tie into AML and Sanctions Screening in the U.S.?
Know Your Customer (KYC) plays a critical role in Anti-Money Laundering (AML) efforts and sanctions screening processes in the U.S. by helping organizations check customers against the Office of Foreign Assets Control (OFAC) list to ensure they are not engaging with sanctioned individuals or entities, integrating sanctions screening into KYC, and supporting risk-based approaches.
How Do U.S. KYC Requirements Compare to Global Standards?
When it comes to Know Your Customer (KYC) regulations, the U.S. follows strict guidelines, but how do they stack up against global standards?
- The U.S. aligns with the Financial Action Task Force (FATF) recommendations, which set the global benchmark for combating money laundering and terrorist financing.
- Europe takes a more digital-first approach with eIDAS and KYC6, which focus on secure electronic identification and verification methods.
- On the other hand, regions like APAC and Latin America are rapidly evolving their KYC frameworks by incorporating technology and biometric verification to meet global best practices.
What Are the KYC Trends in the U.S. for 2025?
Digital identity verification and biometric KYC through facial recognition and fingerprint scanning, AI-powered risk scoring and Unified compliance systems (KYC + AML + Fraud) are the principal trends of 2025 that are worth mentioning.
