Corporate KYC, also called Know Your Business (KYB), is structurally different from individual KYC. An individual has one identity to verify; a company has at least three: the entity itself, the people authorised to act on its behalf, and the natural persons who ultimately own or control it. Each layer needs its own document set, and missing any one of them is enough to fail an audit.
This walkthrough is for compliance and ops leads who own the KYB workflow at a regulated entity, plus the businesses on the other side trying to figure out which documents their bank, NBFC, or fintech onboarding partner actually wants. We will cover the five-pillar framing that organises the document chaos, the entity-by-entity matrix (private limited, LLP, partnership, sole prop, HUF, trust, society, foreign branch), how UBO identification actually works in practice, and the digital KYB workflow that turns 30 documents into one orchestrated decision.
What KYB Is, and How It Differs From Individual KYC
KYB is the regulated-entity verification process that answers three questions about a business customer: does this entity legally exist, who is authorised to act for it, and who ultimately owns or controls it. Individual KYC answers one question: is this person who they say they are.
The structural difference matters because KYB documents are layered. A private limited company submits its Certificate of Incorporation (entity), a board resolution (authorisation), individual KYC for each authorised signatory (signatory), and a shareholding declaration plus UBO KYC (ownership). Four separate document sets, four separate verifications, one combined decision. For individual KYC documents, the equivalent stack is one PoI, one PoA, and a PAN.
The cost of a wrong rejection is also higher in KYB. A wrongly-rejected individual costs the bank a small-balance account; a wrongly-rejected business is a B2B customer with significant lifetime value. KYB workflows tune for fewer false rejections and rely on layered checks rather than single-document decisions.
When KYB applies versus individual KYC
KYB applies any time a regulated entity is onboarding a non-individual customer: opening a current account, extending business credit, onboarding a marketplace seller, accepting a vendor for payment, or signing up an SMB to a SaaS that touches money. Individual KYC applies when the customer is a natural person opening a personal product.
Sole proprietorships sit on the bridge. Legally, the sole prop is the individual; functionally, it is a business. Most banks treat sole-prop current accounts as a hybrid: individual KYC for the proprietor plus a small business-proof set (GST registration, Shop & Establishment licence, professional tax registration).
The Five Pillars of Corporate KYC Documents
Every KYB document fits into one of five categories. Memorising the five pillars is faster than memorising the entity-by-entity matrix.
Pillar 1: Entity proof
The legal existence of the business. For a company, this means the Certificate of Incorporation (COI), the Memorandum and Articles of Association (MOA and AOA), and the entity PAN. For non-companies, the equivalent constitutional documents (partnership deed, LLP agreement, trust deed, society registration certificate).
This pillar answers “does this entity legally exist.”
Pillar 2: Registered address proof
The official address registered with the regulator at incorporation, plus the current operational address if different. Acceptable documents: utility bill in the entity name, property tax receipt, lease deed, GST registration certificate.
This pillar answers “where is this entity legally domiciled.”
Pillar 3: Authorised signatory documentation
The board resolution authorising specific individuals to act for the entity, the list of authorised signatories with specimen signatures, and individual KYC for each named signatory. Banks and lenders use this to know who can legally sign on behalf of the company.
This pillar answers “who can act for the entity, and how do we verify them.”
Pillar 4: UBO (Ultimate Beneficial Owner) documentation
The shareholding declaration showing the chain of ownership and the individual KYC for each natural person identified as a UBO. Per the FATF definition cited in industry references, a UBO is “the natural person(s) who ultimately owns or controls a customer.” The standard threshold is 25% direct or indirect ownership, with stricter thresholds for high-risk customers.
This pillar answers “who actually benefits from this entity, and who controls it.”
Pillar 5: Operational proof
The licences and registrations that prove the business is authorised to operate in its sector: GST registration, trade licences, sector-specific approvals (RBI authorisation for NBFCs, IRDAI for insurers, SEBI for brokers). Not every entity needs every operational proof; the relevant ones depend on the sector.
This pillar answers “is this entity authorised to do what it claims to do.”
KYC Documents Required by Entity Type
The five pillars stay constant. The specific documents that fill each pillar shift by entity type. The matrix below covers the nine entity types regulated entities see most often in India.
Private Limited Company
| Pillar | Documents |
|---|---|
| Entity proof | Certificate of Incorporation, MOA, AOA, entity PAN |
| Address proof | Utility bill in company name, property tax, GST certificate |
| Signatory documentation | Board resolution, list of signatories with specimen signatures, individual KYC for each |
| UBO | Shareholding declaration, KYC of each UBO above 25% (or 10% for high-risk) |
| Operational proof | GST registration, sector licences as applicable |
The UBO mapping is where private limited KYB usually slows down. Layered ownership (a holding company that owns a subsidiary that owns the operating entity) requires walking the chain to the natural person at the top.
Public Limited Company
The document set is the same as private limited, with two additions for listed companies: SEBI listing data (DRHP, latest annual report) and a layered shareholding analysis that handles institutional investors. Listed-company UBO mapping is allowed to stop at the listed-company level rather than tracing each underlying shareholder, which is the practical exception that makes onboarding listed clients possible.
Limited Liability Partnership (LLP)
| Pillar | Documents |
|---|---|
| Entity proof | LLP Certificate of Incorporation, LLP Agreement, LLP PAN |
| Address proof | Utility bill in LLP name, lease deed, GST certificate |
| Signatory documentation | List of designated partners with specimen signatures, individual KYC for designated partners |
| UBO | Designated partners and any partner with greater than 25% economic interest |
| Operational proof | GST registration, sector licences |
The “designated partner” concept is LLP-specific: not every partner can sign for the LLP, only the designated partners. The signatory documentation must list which partners are designated.
Partnership Firm
| Pillar | Documents |
|---|---|
| Entity proof | Partnership Deed, firm PAN |
| Address proof | Utility bill in firm name, lease deed |
| Signatory documentation | Authority letter signed by all partners, individual KYC for all partners |
| UBO | Each partner is a UBO |
| Operational proof | Registration certificate (for registered firms), GST, trade licences |
Unregistered partnership firms can still be customers, but the documentation depth increases because there is no public registry confirming the partnership’s existence.
Sole Proprietorship
The bridge case. Documentation:
- Individual KYC for the proprietor (full PoI, PoA, PAN)
- Two of the following business proofs: GST certificate, Shop & Establishment licence, professional tax registration, IT return acknowledgement, utility bill in firm name, Udyam (MSME) registration
The two-of-the-following rule is industry standard for sole prop current accounts because no single document proves both that the business exists and that the proprietor controls it.
Hindu Undivided Family (HUF)
| Pillar | Documents |
|---|---|
| Entity proof | HUF Deed, HUF PAN |
| Address proof | Utility bill or bank statement in HUF name |
| Signatory documentation | KYC of the Karta (head of the family) |
| UBO | Karta is the UBO; coparceners are listed but typically below threshold |
| Operational proof | Not usually required for HUFs |
Trust, Society, Section 8 Company, NGO
| Pillar | Documents |
|---|---|
| Entity proof | Trust deed / society registration / Section 8 Certificate of Incorporation |
| Address proof | Utility bill in entity name |
| Signatory documentation | KYC of trustees, office bearers, or Section 8 directors |
| UBO | Settlor and trustees for trusts; office bearers for societies |
| Operational proof | 12A and 80G registrations (where applicable for NGOs); FCRA registration for foreign-funding entities |
Activity proof is a common additional ask for NGOs, especially those receiving foreign contributions: brief on operations, list of projects, audited accounts.
Foreign Branch or Liaison Office in India
| Pillar | Documents |
|---|---|
| Entity proof | RBI approval letter (for branches), parent entity COI, apostilled or notarised translations where applicable |
| Address proof | Indian premises lease deed, utility bill |
| Signatory documentation | Authorised representative in India with full KYC |
| UBO | Parent-entity UBO mapping |
| Operational proof | RBI approval defining the scope of permitted activities |
Foreign-branch KYB is the slowest entity type to onboard because the apostille and notarisation requirements add weeks. Most banks specialise this workflow under a dedicated team.
UBO Identification: How It Actually Works
The UBO pillar is where most KYB processes stall. Three sub-questions shape the work.
The 10, 15, 25 percent threshold framework
The default global threshold for UBO identification is 25% direct or indirect ownership or voting rights. India’s RBI Master Direction on KYC follows the FATF standard with adjustments for risk class. Industry guidance on UBO compliance confirms 25% as the prevailing threshold across major jurisdictions.
For high-risk customers, the threshold drops:
- Standard customers: 25% beneficial ownership triggers UBO identification
- Higher-risk customers (cross-border ownership, complex structures): 15% threshold is common
- Highest-risk customers (sanctioned-jurisdiction exposure, opaque ownership): 10% threshold may be applied
Risk class is set at onboarding by the bank’s policy and reviewed periodically.
Layered ownership and control mapping
The complication every KYB team encounters: ownership rarely runs in a flat line. A small operating company may be owned by a single holding company, which is owned by another holding company, which is owned by a family trust, which has individual beneficiaries. The KYB process has to walk the chain to the natural persons at the top.
A worked example. Operating Company A is 100% owned by Holdco B. Holdco B is 60% owned by Holdco C and 40% owned by Family Trust D. Holdco C is owned by an individual, Mrs Sharma (60%), and another individual, Mr Patel (40%). Family Trust D’s beneficiaries are Mrs Sharma’s children. The UBO calculation:
- Mrs Sharma’s effective ownership of A: 60% × 60% = 36% direct, plus indirect benefit through Family Trust D (which she controls as settlor): combined effective ownership above the 25% threshold
- Mr Patel’s effective ownership of A: 40% × 60% = 24%, just below the standard threshold
- Family Trust D beneficiaries: depends on whether the bank treats trust beneficiaries as UBOs (jurisdiction-specific)
In production, the calculation is automated through a beneficial-ownership graph; manual UBO tracing across more than two layers is error-prone.
When UBO cannot be identified
Two scenarios where UBO identification at the natural-person level is impossible or impractical.
The listed-company exception: when a listed company is at the top of the ownership chain, the bank does not have to walk further. The listed company is treated as the UBO endpoint.
The senior-managing-official fallback: when ownership is genuinely diffuse (no single person above the threshold) and the bank has done reasonable due diligence, the senior managing official (typically the CEO or Managing Director) is documented as the responsible person in lieu of a UBO.
Both exceptions require explicit policy documentation in the bank’s KYB process.
Digital KYB Workflow: From Upload to Decision
A modern KYB workflow runs all five pillars in parallel rather than sequentially. The five-pillar framing maps directly onto five service calls in a know your business orchestration engine.
Document upload plus OCR and data extraction
The customer uploads documents through a portal. OCR engines extract field-level data: company name from COI, PAN from the entity PAN card, registered address from MOA, designated partners from LLP agreement. Field-level confidence scores tell the workflow which extractions are clean enough to proceed and which need human review. OCR-based document extraction is the cheapest layer of the KYB pipeline.
Registry validation
OCR alone is not enough. Each extracted field gets validated against an authoritative registry:
- MCA Master Data API for company details (COI, directors, shareholding)
- GSTN API for GSTIN status and address
- PAN bulk verification API for entity PAN
- VAHAN where vehicle-related verifications apply
Each registry call is independent of the others and adds confirmation. A KYB engine that only OCRs the documents without registry validation is missing the strongest signal in the chain.
Signatory KYC
Each authorised signatory triggers an individual KYC pipeline: face match, liveness, OVD verification. The same engine that powers biometric authentication and face detection handles signatory verification at scale, often through Video KYC for the named signatories.
UBO identification and risk scoring
The shareholding declaration feeds into a beneficial-ownership graph. Risk scoring inputs include: industry sector (gambling and crypto are higher risk), geography (cross-border or sanctioned-jurisdiction exposure), ownership opacity (number of layers, presence of nominee structures), and PEP/adverse-media signals on identified UBOs.
The output is a risk classification (low, medium, high) that determines how much manual review the rest of the process needs. AML solutions typically integrate at this step.
Decision with audit log
The orchestration produces one of three outputs: auto-approve (all checks clean, low risk), manual review (one or more checks flagged), or reject (clear breach). The audit log records every check, every decision, every override, with timestamps. RBI inspections check this log; a clean audit log is the evidence the bank’s KYB process is compliant.
Finance-verification industry workflows standardise this orchestration across the major Indian regulated entities.
Common KYB Rejection Reasons
The patterns that explain most flagged KYB applications.
Stale entity documents
A Certificate of Incorporation from incorporation day, with no record of subsequent name changes, share transfers, or director additions. The MCA Master Data shows a different director list than the one in the application. The fix: pull current MCA filings before submitting; do not rely on the original COI alone.
Missing or incorrect board resolution format
The board resolution authorising the signatory is not in the format the bank requires (missing the meeting date, missing the resolution number, signed by a non-director). Banks publish their preferred format; using it removes one of the most common rejection reasons.
UBO ambiguity
The declared UBO does not match the shareholding pattern. Most often this is a paperwork error rather than concealment: the declaration lists the founder as the UBO, but the cap table shows external investors above the 25% threshold. The fix: reconcile the declaration with the current cap table before submitting.
Signatory KYC mismatch
The authorised signatory’s individual KYC documents do not match the records on file. A name change after marriage, a corrected Aadhaar address, or a new PAN that has not been linked. The fix is upstream: keep individual KYC current for everyone who signs for the entity.
KYB Compliance Landscape in 2026
Two threads have shaped the KYB workflow over the last 18 months.
RBI Master Direction updates
The RBI Master Direction on KYC has been refreshed in cycles, with the most recent updates tightening UBO documentation expectations and adjusting periodic-update cycles for higher-risk entities. Recent RBI amendments to the KYC Master Direction are worth reading in full for compliance teams running their next inspection-prep cycle.
The practical effect: banks now refresh KYB for high-risk entities every 2 years rather than waiting for trigger events. UBO declarations have to be re-confirmed at each refresh, which has surfaced a long tail of businesses whose declared UBO no longer matches their current cap table.
DPDP Act implications for storing entity and signatory data
The Digital Personal Data Protection Act, 2023, with the DPDP Rules notified in November 2025, treats entity-related personal data (signatory KYC, UBO KYC) as personal data subject to the same consent and purpose-limitation rules that apply to individual KYC. The retention windows for KYB records have to align with the loan or account tenure plus the regulatory record-keeping requirement.
Cross-border transfer restrictions matter for foreign-branch KYB: if the bank is using a vendor that processes documents outside India, the DPDP framework applies. Most major Indian banks have moved to India-resident processing for KYB workloads as a result.

FAQs
What documents are required for KYC of a private limited company in India?
Certificate of Incorporation, Memorandum and Articles of Association, entity PAN, registered address proof (utility bill or property tax receipt in company name), board resolution authorising signatories, individual KYC for each authorised signatory, shareholding declaration, UBO KYC for each beneficial owner above the 25% threshold, and GST registration where applicable.
What is the difference between KYC and KYB?
KYC is the regulatory verification of an individual customer’s identity. KYB (Know Your Business) is the equivalent for a business customer, with three layers: the entity itself, the people authorised to act for it, and the natural persons who ultimately own or control it. KYB requires more document categories than individual KYC.
Who is a UBO and how is the UBO identified?
A UBO (Ultimate Beneficial Owner) is the natural person who ultimately owns or controls an entity, typically defined as anyone with 25% or more direct or indirect ownership. UBO identification walks the ownership chain from the operating entity through any holding companies and trusts to the natural persons at the top.
Is GST registration required for KYB?
GST registration is required for KYB if the entity is GST-registered. Not every business is required to register for GST, so the documentation depends on turnover and sector. Where GST registration exists, banks typically require the GST certificate as part of operational proof and run a GSTN API check during verification.
What documents does an LLP need for KYC?
LLP Certificate of Incorporation, the LLP Agreement, LLP PAN, registered address proof, list of designated partners with specimen signatures, individual KYC for designated partners, UBO declaration covering any partner with greater than 25% economic interest, and GST registration where applicable. Non-designated partners are listed but not signatories.
How long does corporate KYC take?
A clean KYB application with current documents and a cooperative cap table closes in 2 to 5 working days at most major Indian banks. Foreign-branch onboarding takes longer (often 2 to 4 weeks) because of apostille and notarisation requirements. Sole proprietorships often close same-day if the proprietor’s individual KYC is already on file.
What happens if UBO cannot be identified?
When ownership is genuinely diffuse and no single person crosses the threshold after reasonable due diligence, the senior managing official (typically the CEO or Managing Director) is documented as the responsible person in lieu of a UBO. This requires explicit policy documentation in the bank’s KYB process and is treated as a higher-risk path requiring more frequent review.
Are foreign company documents accepted for KYB in India?
Yes, with apostille or notarisation depending on the country of origin. Foreign-branch KYB requires the parent entity Certificate of Incorporation, RBI approval where applicable, an authorised representative in India with full individual KYC, and translation of any non-English documents. The path is slower than domestic KYB and usually handled by specialist teams.
