Due Diligence for NBFCs in India: Process, Checklist and Red Flags

Published on 10/8/2026

Due diligence for NBFCs in India is a structured review of a non-banking financial company’s loan book, financials, RBI compliance, governance, funding, and technology before an investment, acquisition or lending decision. An NBFC’s real risk sits in its loan portfolio and regulatory standing, so the review goes much deeper on asset quality, liquidity, and compliance than a standard company audit.

RBI regulatory layers for NBFCs

₹1,000 Cr

Asset size dividing Base and Middle layers

₹10 Cr

Minimum NOF for ICC, MFI, Factors by 31 Mar 2027

90 days

NPA recognition norm (glide path to 31 Mar 2026)

An NBFC can look healthy on paper and still be one bad quarter away from trouble. Reported profits may rest on loans that are quietly being rolled over. A comfortable balance sheet may hide a gap between what the company owes lenders next year and what it will collect from borrowers.

That is why due diligence for NBFCs in India is a specialised exercise. The buyer or investor is not just buying a company. They are buying a loan book, a licence and a funding relationship, and each of these carries its own risk.

This guide explains how NBFC due diligence works, what the RBI framework means for it, and what a practical NBFC due diligence checklist looks like. It also lists the red flags that experienced reviewers look for first.

🏦Why NBFC Due Diligence Is Different From Regular Company Due Diligence

In a manufacturing or services business, due diligence focuses on revenue, margins, contracts, and assets. In a lending business, the “product” is credit, and the main asset is a portfolio of loans that can go bad. Three things make NBFC due diligence different:

📉

Earnings quality depends on provisioning

If an NBFC under-provisions for bad loans, profits look better than they are. Reviewers therefore test whether provisions match the real condition of the portfolio.

💧

Funding is part of the business model

An NBFC borrows from banks, markets and other institutions, and lends for longer periods. Mismatches between the two, along with covenant breaches, can create a liquidity crisis even when the loans are performing.

📜

The licence is a regulated asset

An NBFC operates under the RBI’s supervision, so non-compliance can lead to penalties, restrictions on business or, in the worst case, cancellation of the Certificate of Registration. A deal can fail on regulatory grounds alone.

⚖️ Regular vs NBFC Due Diligence at a Glance

Focus Area	Regular Company	NBFC
Main asset	Revenue, contracts and operating assets	A portfolio of loans that can go bad
Earnings test	Revenue and margins	Provisioning and asset quality
Funding	Capital structure	Borrowing mix, covenants and liquidity gaps
Regulator	Sector and general company law	RBI supervision and the Certificate of Registration
Where risk sits	Operations and commercial performance	Credit quality and regulation

📈RBI Scale-Based Regulation: What It Means for Due Diligence

Any regulatory due diligence for NBFCs starts with the layer the company sits in. Under RBI scale based regulation, NBFCs are placed in four layers according to their size, activity, and perceived risk. The higher the layer, the stricter the rules:

TOP LAYER

Kept for NBFCs where RBI sees a sharp rise in systemic risk. It stays empty unless the RBI moves a company into it.

UPPER LAYER

The ten largest NBFCs by asset size, plus others RBI identifies, with stricter prudential and governance requirements.

MIDDLE LAYER

Deposit-taking NBFCs, non-deposit-taking NBFCs with assets of ₹1,000 crore and above, and categories such as housing finance companies, infrastructure finance companies and core investment companies.

BASE LAYER

Mainly non-deposit-taking NBFCs with assets below ₹1,000 crore.

The layer decides which rules apply to capital, governance, disclosures and risk management. A reviewer must confirm that the NBFC is in the correct layer and meets the requirements for that layer. Two other points from the framework matter in a review:

📌 NET OWNED FUND

The minimum NOF for NBFC-ICC, NBFC-MFI and NBFC-Factors is rising to ₹10 crore by 31 March 2027, so a target close to the old thresholds may face a capital top-up.

📌 NPA RECOGNITION

RBI set a glide path to a 90-day overdue norm for recognising non-performing assets by 31 March 2026, so any NBFC whose asset classification looks softer than this deserves a closer look.

⚠️ Rules change often. Every review should be checked against the RBI’s current Master Directions at the time of the transaction.

🤝Who Needs Due Diligence for NBFCs, and When

NBFC investment due diligence is not only for buyers. Several parties use it:

💼

PE and VC funds

Use it before investing in an NBFC or fintech lender to confirm that growth is backed by quality assets.

🏢

Acquirers

Use NBFC acquisition due diligence to understand what they are taking over, including hidden liabilities, portfolio stress and regulatory approvals.

🏛

Banks and lenders

Review an NBFC before sanctioning or renewing credit lines.

🔗

Co-lending and fintech partners

Check partner NBFCs before sharing portfolios or customer data.

🏷

The NBFC itself

Commission a sell-side or vendor review before a fundraise, a sale or an IPO, so that problems are found and fixed before a buyer finds them. Our guide on buy-side vs sell-side financial due diligence explains the difference.

✅NBFC Due Diligence Checklist: What Gets Reviewed

A complete NBFC due diligence checklist covers eight areas.

📋

Corporate and Licence Review

Confirm the Certificate of Registration, the NBFC category and the regulatory layer. Check the net owned fund against the minimum requirement and look at the shareholding pattern and the track record of directors and key managers.

Also check how past changes in shareholding or control were handled. RBI generally requires prior approval for a change in control or a significant change in shareholding, and the threshold has been 26 percent. Confirm this against the current directions, because it decides whether a transaction needs regulatory approval and how long it will take.

📊

Financial Due Diligence for NBFCs

Financial due diligence for NBFCs tests the quality and sustainability of earnings. Reviewers look at:

✔Net interest margin, yield on loans and cost of funds over several years.
✔Operating cost ratios and credit cost.
✔Fee and processing income, and whether it is recognised properly.
✔The accounting framework. NBFCs above the net worth threshold follow Ind AS with expected credit loss provisioning, while smaller ones follow RBI prudential norms. Reviewers compare the two views to see whether provisions are adequate.
✔Audit quality, qualifications in audit reports and any change of auditors.

For a wider view of the process, see our guide to financial due diligence services in India.

🔬

Loan Book and Asset Quality Review

This is the heart of the exercise. A proper loan book review includes:

✔Portfolio stratification by product, ticket size, geography, borrower type and interest rate.
✔Gross and net NPA trends, write-offs and restructured loans.
✔Vintage and roll-rate analysis, which show how loans behave as they age.
✔Concentration risk, whether in a few borrowers, one sector or one region.
✔Sample testing of loan files for sanction approval, documentation, security creation and end-use checks.
✔Collateral and loan-to-value levels, especially in secured and gold loans.
✔Evidence of evergreening, where a new loan is used to repay an old stressed one.

💧

Liability, Liquidity and ALM Review

Review the borrowing mix across bank lines, debentures, commercial paper and other sources. Check covenants and any past breaches. Study the asset-liability maturity profile to see whether the company can meet obligations over the next year without fresh funds. Also check dependence on one or two large lenders, which can become a risk if a lender pulls back.

🛡

Regulatory and Compliance Review

Regulatory due diligence for NBFCs checks whether the company follows RBI rules in practice, not just on paper. Typical areas include:

✔Statutory returns, past RBI inspection reports and any penalties.
✔KYC and anti-money laundering compliance under the PMLA framework.
✔Fair practices code, interest rate disclosure, recovery practices and grievance redress.
✔Digital lending compliance, including loan service provider arrangements and RBI’s cap on default loss guarantees.
✔Outsourcing and co-lending arrangements.
✔Timely credit bureau reporting.
✔Sector-specific rules for microfinance, gold loans and housing finance, where they apply.

👥

Governance and Related-Party Review

Check board composition, independent directors, audit and risk committees, and key-person dependence. Examine transactions with promoters and group companies, any promoter share pledges and whether related-party dealings are on arm’s-length terms.

⚖️

Legal, Tax and Security Review

Review pending litigation, consumer complaints, recovery proceedings and any regulatory notices. Check tax assessments, GST and TDS compliance, and whether charges on assets are properly registered with the Registrar of Companies and the central security interest registry.

💻

Technology, Data and Cyber Review

A lender runs on its loan management system. Check whether loan data in the system matches the books, how reliable the data is, how access is controlled, what the cyber security posture looks like and how dependent the company is on technology vendors and partners. Poor data integrity makes every other number harder to trust.

💡 Pro tip: Always confirm the 26 percent change-of-control threshold against current RBI directions before fixing the deal timeline, because approval time can set the whole schedule.

🚩Red Flags in NBFC Due Diligence

Experienced reviewers watch for these ten warning signs:

🚩 A big gap between reported NPAs and what the loan-level data shows.	🚩 High levels of restructured or rolled-over loans.
🚩 Heavy concentration in a few borrowers or a single sector.	🚩 A large asset-liability mismatch or reliance on short-term borrowing for long-term loans.
🚩 Frequent changes of auditors or repeated audit qualifications.	🚩 Significant related-party lending or promoter share pledges.
🚩 Past RBI penalties, repeated compliance lapses or unresolved inspection findings.	🚩 Delays in credit bureau reporting or inconsistent data between systems.
🚩 Heavy dependence on one co-lending or guarantee partner.	🚩 Growth that is much faster than the company’s systems and collections capacity.

💡 One red flag rarely ends a deal. A pattern of them usually changes the price, the deal structure or the protections written into the agreement.

🧭The NBFC Due Diligence Process and Timeline

A typical review follows six steps:

1	STEP 1 Scoping Define the purpose, the depth of review and the key concerns.
2	STEP 2 Data room and information request The NBFC shares financial, legal, regulatory and portfolio data.
3	STEP 3 Management discussions Reviewers interview key people on strategy, credit policy and collections.
4	STEP 4 Loan file and portfolio testing Analysts test a sample of loans and run portfolio analytics.
5	STEP 5 Analysis and findings Issues are rated by severity and linked to value or risk.
6	STEP 6 Report and recommendations The findings feed into pricing, conditions and the share purchase or investment agreement.

The timeline depends on the size of the loan book, the quality of the data and how quickly management responds. A small NBFC with clean records moves faster than a large, multi-product lender with scattered data. Our article on how long due diligence takes gives realistic ranges for Indian transactions.

💬Frequently Asked Questions

What is due diligence for NBFCs in India?

Due diligence for NBFCs in India is a structured review of an NBFC’s loan book, financial statements, RBI compliance, governance, funding and technology before an investment, acquisition or lending decision. It checks whether reported numbers are reliable, whether the company follows RBI rules and what risks could affect value after the deal.

Why is due diligence important before acquiring or investing in an NBFC?

An NBFC’s value depends on the quality of its loans and its regulatory standing, and both can hide risk. Due diligence tests asset quality, provisioning, liquidity and compliance, so buyers and investors can price the deal correctly, negotiate protections and avoid hidden liabilities or licence problems.

What does an NBFC due diligence checklist include?

An NBFC due diligence checklist covers corporate and licence status, financials and provisioning, loan book and asset quality, borrowings and asset-liability management, RBI compliance, governance and related-party dealings, legal and tax matters, and technology and data integrity. The depth of each area depends on the deal type and the company’s regulatory layer.

Is RBI approval required to acquire an NBFC?

Generally yes. RBI requires prior approval for a change in control or a significant change in shareholding of an NBFC, and the threshold has been 26 percent of paid-up equity. Rules can change, so confirm the current directions and plan for approval time when setting the transaction timeline.

What are the biggest red flags in NBFC due diligence?

The biggest red flags are weak asset quality that is not fully reflected in reported NPAs, high restructured or rolled-over loans, heavy borrower or sector concentration, large asset-liability mismatches, repeated compliance lapses, related-party lending and inconsistent data between the loan system and the books.

How long does due diligence for an NBFC take?

It varies with the size and complexity of the NBFC. A smaller lender with organised records can be reviewed faster, while a large multi-product NBFC with many branches and partners takes longer. Data quality and management responsiveness have the biggest effect on the timeline, so a prepared data room helps.

How is NBFC due diligence different from regular company due diligence?

Regular due diligence focuses on revenue, margins and operating assets. NBFC due diligence adds a deep review of the loan portfolio, provisioning, funding and liquidity, and RBI compliance, because a lender’s risk sits in credit quality and regulation more than in physical assets.
