Top 7 FinTech Compliance Requirements (KYC, KYB, AML, SOC 2, PCI, FFIEC) for US Apps



A FinTech product can have a polished interface and a respected bank partner—and still miss its launch because compliance entered the conversation too late.


In the United States, compliance is not a document added before release. It shapes onboarding, permissions, transaction monitoring, payment architecture, data retention, vendor selection and customer support. The relevant FinTech compliance requirements depend on what the app does, where it operates, whose licence it uses and what data or funds it handles.


It is also important to use the terms accurately. KYC, KYB and AML describe financial-crime controls. PCI DSS is a payment-card security standard. SOC 2 is an assurance framework, not a licence. FFIEC publishes guidance and examination resources, while GLBA is a federal financial privacy and security law.


This guide explains what each area means for US product and engineering teams. It is general information, not legal advice; confirm your obligations with qualified US counsel, compliance specialists and sponsoring institutions.

Before selecting vendors, map the product: who holds funds, who moves money, which entity has the customer relationship, where data travels and which party performs each control. A bank, BaaS provider or verification vendor may perform work, but outsourcing a task does not automatically outsource accountability.


1. KYC Compliance Requirements for FinTech Apps


Know Your Customer is the broad term for establishing who an individual customer is and assessing their risk. For covered US financial institutions, formal obligations may include a written Customer Identification Program (CIP) within the Bank Secrecy Act framework.


Onboarding commonly collects a legal name, date of birth, residential address and identification number. Verification might use government documents, authoritative databases, address and phone signals, document validation or liveness checks. The correct approach should reflect the product, customer and risk—not simply whichever fields a vendor API provides.


Good FinTech software development treats verification as a workflow rather than one pass/fail call. The application needs status and reason codes, retry journeys, manual review, secure document handling and a complete decision trail. Higher-risk customers may require enhanced due diligence or later re-verification.


Build into the app: configurable rules, identity-vendor abstraction, role-based review queues, consent evidence, immutable audit events and restricted account states.

2. KYB Compliance and Beneficial-Ownership Verification


Know Your Business verifies a legal entity rather than only the person opening an account. A KYB process may confirm the business’s legal name, EIN, formation jurisdiction, status, addresses, industry, expected activity and source of funds. It should also establish who controls and ultimately owns the entity.


FinCEN’s Customer Due Diligence framework requires covered institutions to identify and verify qualifying beneficial owners of legal-entity customers, understand the purpose of the relationship and conduct ongoing monitoring. Exact responsibilities depend on the institution and programme.


A business-onboarding data model must support multiple owners, control persons and authorised users. More complex structures may contain indirect ownership across several entities. Store the evidence behind ownership calculations, preserve historical relationships and trigger review when material details change.


Do not confuse customer due diligence with Corporate Transparency Act reporting. FinCEN removed BOI reporting requirements for US companies and US persons in 2026; that change does not automatically remove a financial institution’s customer-verification duties or a sponsor bank’s KYB requirements.


Build into the app: state-registry checks, entity documents, ownership graphs, business and owner screening, exception handling, risk classification and event-driven re-verification.


3. BSA/AML and OFAC Requirements for US FinTech


Transaction monitoring should compare activity with a customer’s expected behaviour and risk. Useful scenarios can include unusual velocity, structuring, rapid movement of funds, unexpected counterparties, geographic anomalies, mule-account patterns and sudden departures from established activity.


When a rule or model creates an alert, an analyst needs context: customer history, linked accounts, transactions, prior alerts and the rule version that fired. The case system should record evidence, investigation notes, decisions, approvals and escalation. It should never let an analyst quietly close a case without a rationale.


OFAC sanctions compliance is related but distinct. Screening may cover customers, businesses, beneficial owners and payment counterparties during onboarding and throughout the relationship. Reliable workflows combine fuzzy matching with secondary identifiers and human review to manage false positives.


Not every FinTech files Suspicious Activity Reports directly. Responsibility may sit with a regulated bank or another programme party. Define data access, escalation paths, decision rights and confidentiality in the responsibility matrix.


Build into the app: real-time and batch monitoring, configurable rules, sanctions rescreening, case management, restricted SAR-related information, quality review and versioned decisions.


4. SOC 2 Requirements for FinTech Software Development


SOC 2 is not a US FinTech law or regulatory licence. It is an independent examination based on the AICPA Trust Services Criteria. Banks, investors and enterprise customers often request it because it provides evidence that controls are not merely promised but documented and, for Type II reports, operated over a period.


Security is included in every SOC 2 examination. Availability, processing integrity, confidentiality and privacy may be added according to the service and customer commitments. A Type I report assesses control design at a point in time; Type II examines design and operating effectiveness across a review period.


When comparing FinTech software development companies, ask how engineering practices generate audit evidence automatically. Pull-request approvals, deployment records, access logs and security findings should be traceable without a frantic collection exercise before the audit.


Build into the operation: clear control owners, realistic policies, automated evidence, asset inventory, vendor reviews, incident exercises and recurring access reviews.


5. PCI DSS Compliance for Payment Applications


PCI DSS provides technical and operational requirements for environments that store, process or transmit payment-account data. PCI DSS v4.0.1 is the active version supported by the PCI Security Standards Council.


Scope starts with data flow. Map card-entry forms, mobile SDKs, APIs, servers, logs, analytics, support tools, backups and connected administrative systems. Card details leaking into logs or customer-service platforms can expand scope unexpectedly.


Architecture can reduce exposure. Processor-hosted fields, tokenisation and avoiding raw card storage may shrink the cardholder-data environment, although they do not necessarily remove every obligation. Never retain sensitive authentication data such as card verification codes after authorisation.


Validation may involve a Self-Assessment Questionnaire, Attestation of Compliance, Report on Compliance, scans or penetration testing. The appropriate route depends on the company’s role, architecture, transaction volume and requirements from acquirers or card brands.


Experienced mobile banking app development teams design payment boundaries before screens and APIs harden around a risky flow.


Navigate KYC, KYB, AML & Other US Compliance Requirements





Build into the app: tokenised payments, segmentation, encryption, least privilege, redacted logs, change detection, vulnerability management and monitoring of payment-page scripts.


6. FFIEC Expectations for Banking App Development


The Federal Financial Institutions Examination Council publishes guidance and examination resources used by US banking regulators. There is no universal “FFIEC certification” for a FinTech startup. However, a regulated bank must manage third-party risk, so its technology partner may need to demonstrate FFIEC-aligned controls.


Relevant areas include authentication, information security, architecture, development, operations, business continuity, cybersecurity and vendor management. FFIEC authentication guidance emphasises risk assessment, layered security and access controls for customers, employees and third parties.


A secure cloud banking software architecture should also prove how it recovers. Test backup restoration, dependency failure, degraded operations and communications—not just whether backups exist.


Build into the platform: multifactor authentication, privileged-access management, vendor oversight, tested recovery, system inventories, security monitoring and auditable change management.


7. GLBA Privacy and Safeguards Rule Compliance


The Gramm-Leach-Bliley Act protects consumers’ nonpublic personal information. Covered financial institutions must explain certain information-sharing practices and safeguard customer information. Applicability depends on the business and regulator, so it requires legal analysis rather than assumption.


The Privacy Rule affects notices, disclosures and opt-out rights where applicable. The FTC Safeguards Rule requires covered institutions under its jurisdiction to maintain a written information-security programme with administrative, technical and physical safeguards.


For product teams, this begins with knowing what data exists, why it was collected, where it is stored, who can access it and when it should be deleted. A generic privacy policy cannot repair an undocumented data flow. Vendors receiving customer information also require due diligence and contractual oversight.


Build into the product: data inventory, classification, encryption, multifactor authentication, retention schedules, secure disposal, vendor controls, incident response and senior-management reporting.


How FinTech Development Services Can Build Compliance In


Compliance works best as architecture, not an audit-season project. During discovery, create a funds-flow map, regulatory-perimeter assessment, data inventory and responsibility matrix. Then convert each obligation into product requirements, technical controls, operational procedures and evidence.


A qualified FinTech development company should help reduce regulated-data exposure, separate high-risk services and preserve traceable decisions. Look for custom FinTech software development services that understand identity, banking APIs, payment processors, cloud security and compliance operations—not only interface development.


Final FinTech Compliance Checklist for US Apps


  • Map the product, funds, entities, data and vendors.

  • Confirm federal, state and partner-bank obligations.

  • Assign each control to the FinTech, bank, BaaS provider or vendor.

  • Build KYC and KYB exception paths, not only happy paths.

  • Connect customer risk to transaction monitoring.

  • Reduce card-data scope before implementing payments.

  • Align security controls with SOC 2, FFIEC and GLBA needs.

  • Test access, incident response and recovery.

  • Retain evidence without collecting data indefinitely.

  • Review regulations, vendors and controls continuously.


The right FinTech software development services do more than make an app functional. They help make its decisions explainable, its sensitive data defensible and its controls sustainable.

Frequently Asked Questions


What compliance requirements apply to a US FinTech app?


That depends on its activities, licences, states, data and partners. Common areas include KYC, KYB, BSA/AML, OFAC, GLBA and PCI DSS. Banks may also require SOC 2 reporting and controls aligned with FFIEC guidance.


Is SOC 2 legally required for FinTech companies?


SOC 2 is not generally a federal licence or law. It can become commercially or contractually necessary when banks, BaaS providers, investors or enterprise customers require independent assurance about security controls.


What is the difference between KYC and KYB?


KYC verifies an individual and assesses customer risk. KYB verifies a legal entity and may identify its beneficial owners, control person and authorised users. Business onboarding often needs both.


Does using a payment processor remove PCI DSS obligations?


Not automatically. Hosted fields and tokenisation can reduce scope, but a merchant or service provider may retain validation and security responsibilities. Confirm the applicable questionnaire or assessment with the acquirer and a PCI specialist.


Does a sponsor bank handle all FinTech compliance?


No. A bank may own particular regulatory decisions, but the FinTech still operates technology, gathers data and performs contracted controls. Responsibilities, escalation routes, evidence access and oversight should be documented before development and revisited as the product changes.
