Complete Guide to GST and Compliances for Finance and Banking Sector in India

Finance and banking is the sector where GST law draws its sharpest line between money and service. Lend someone money and charge interest, no GST applies at all. Charge a processing fee for that same loan, and 18% GST applies immediately. This single distinction, between the exempt financial transaction and the taxable service wrapped around it, shapes almost every GST question a bank, NBFC, or financial services business runs into.

This guide covers the licenses a financial services business needs, exactly where GST applies and where it doesn't, the NBFC-specific ITC rule that doesn't exist anywhere else in GST law, and the mistakes that most often trip up banks and NBFCs with multi-state operations.

Licenses a Finance or Banking Business Needs

RBI Banking License. Required to operate as a bank, issued under the Banking Regulation Act, 1949. Full banking licenses are rarely granted to new entrants and involve an extensive RBI approval process; most new financial services businesses instead operate as an NBFC.

NBFC Certificate of Registration (CoR). Mandatory under Section 45-IA of the RBI Act, 1934, for any company providing loans, asset financing, investment services, or microfinance without holding a full banking license. As of 2026, this requires a minimum Net Owned Fund of ₹10 crore for most categories, incorporation under the Companies Act, and directors with a clean credit history, processed through RBI's COSMOS portal, typically taking 3 to 6 months. RBI's 2026 Scale Based Regulation framework has also introduced a narrow exemption category for entities with no public funds and no customer interface below a ₹1,000 crore asset threshold, so it's worth checking current classification before assuming registration is mandatory in every case.

FIU-IND Registration. Required with the Financial Intelligence Unit for compliance with the Prevention of Money Laundering Act (PMLA), applicable to NBFCs, banks, and most regulated financial intermediaries.

Credit Information Company (CIC) Membership. NBFCs extending credit typically need membership with all four credit bureaus, CIBIL, Equifax, Experian, and CRIF High Mark, to report and access borrower credit data.

CERSAI / C-KYC Registration. Required for registering security interests and centralised KYC records as part of standard lending compliance.

IRDAI License. Required separately for any insurance-related business, issued by the Insurance Regulatory and Development Authority of India, entirely distinct from RBI's banking and NBFC framework.

SEBI Registration. Required for stockbrokers, mutual fund distributors, portfolio managers, and other capital markets intermediaries, issued by the Securities and Exchange Board of India.

GST Registration. Covered in detail below, and a near-universal requirement for any financial services business with taxable fee-based revenue.

Input Service Distributor (ISD) Registration. Now mandatory, not optional, for any head office or centralised unit that receives invoices for services shared across branches with different GSTINs under the same PAN, effective from 1 April 2025. This is especially relevant for banks and NBFCs with multi-state branch networks, covered further below.

GST Registration Rules for Financial Services Businesses

Registration is mandatory once taxable turnover crosses ₹20 lakh (₹10 lakh in special category states), the standard threshold for services. In practice, almost every bank, NBFC, and financial intermediary registers regardless of size, since fee-based income (processing charges, account maintenance, card fees) is taxable from the first transaction once registered, and most financial businesses operate across multiple states, requiring separate registration in each. Our GST turnover limit guide covers how this is calculated.

GST on Loans, Interest, and Financial Services: What's Exempt and What Isn't

The loan amount and interest are not taxable. Neither the principal disbursed nor the interest or discount charged on a loan is a supply of goods or services under GST, so no GST applies to either, whether the lender is a bank or an NBFC. This holds for personal loans, home loans, business loans, and credit facilities alike.

Fee-based services attract 18% GST. Everything wrapped around the loan or account that isn't the interest itself is generally taxable at 18%: loan processing fees, foreclosure and prepayment charges, documentation fees, card issuance and annual fees, ATM charges beyond free limits, cheque bounce charges, RTGS/NEFT/IMPS service fees, account maintenance charges, and SMS alert fees. A business taking a loan for business purposes can claim ITC on the GST paid on these charges; a loan taken for personal use or exempt activity doesn't carry that ITC benefit.

Corporate guarantees have a specific valuation rule. Where one entity provides a corporate guarantee for a related party, typically a parent guaranteeing a subsidiary's loan, Rule 28(2) of the CGST Rules deems the value of that guarantee service to be 1% of the guaranteed amount per annum, or the actual consideration charged, whichever is higher, regardless of whether the loan is ever actually drawn down. This applies independent of the recipient's ITC eligibility and has been the subject of significant litigation and clarification through CBIC circulars; genuinely commercial bank guarantees issued in the ordinary course of business are treated differently from intra-group corporate guarantees, so the distinction matters.

Insurance premiums. Following the September 2025 GST 2.0 reforms, individual life and health insurance premiums were moved to a nil GST rate, a significant change from the earlier 18% rate. Group insurance and other commercial insurance categories don't automatically follow the same treatment, so it's worth checking classification carefully rather than assuming the exemption is universal. See our detailed piece on health insurance premiums and the zero-GST change for what actually changed for policyholders and insurers.

Capital markets and mutual fund services. Broking commissions, portfolio management fees, and distributor commissions on mutual funds are taxable financial services, generally at 18%. See our guide on GST's impact on mutual funds and stock market investments for how this affects investor returns and fund-level costs.

UPI and digital payment processing. Person-to-person and person-to-merchant UPI transactions themselves don't attract GST, though the payment processing and gateway services layered on top of certain merchant transactions can. See our GST on UPI payments guide for the current position.

The NBFC-Specific 50% ITC Rule

This is a rule that exists nowhere else in GST law and catches many NBFCs off guard. Because an NBFC's core output, lending and accepting deposits, is largely outside GST (interest is exempt), the normal input tax credit apportionment under Section 17(2) can get administratively heavy. GST law gives banks, financial institutions, and NBFCs engaged in lending or deposit-taking a specific alternative: instead of tracking and apportioning ITC precisely between taxable and exempt activity, they can elect to claim a flat 50% of eligible input tax credit on inputs, capital goods, and input services every month, with the remaining 50% simply lapsing.

The catch is that this election, once made for a financial year, cannot be withdrawn during the remainder of that year. An NBFC has to commit to either the proportionate method or the flat 50% method at the start of the year and live with that choice for twelve months, which makes the initial decision a genuine planning exercise rather than a routine filing detail. The 50% restriction also doesn't apply to supplies between two registered entities under the same PAN, which matters for NBFC groups structured across multiple groups companies. See our guides on how to calculate input tax credit, whether ITC applies to all purchases, and the 180-day payment rule under Section 16(2) for the broader ITC framework this special rule sits alongside.

ISD: Mandatory Credit Distribution for Multi-Branch Financial Businesses

Since 1 April 2025, Input Service Distributor registration is no longer an optional alternative to cross-charging; it's mandatory for any head office, corporate office, or centralised unit that receives invoices for services shared across branches holding different GSTINs under the same PAN. This is squarely relevant for banks and NBFCs, where centralised procurement, advertising, IT infrastructure, legal services, auditor fees, is the norm and branches are frequently registered separately across states. ISD registration has to be taken in the state where the common input service is received, credit is distributed to branches proportionate to each branch's turnover, and the ISD has to file a monthly GSTR-6 return. Distributing credit incorrectly, or continuing to rely on the older cross-charge approach after the mandatory ISD switch, exposes the credit to recovery with interest.

Common GST Mistakes in Finance and Banking

Charging GST on interest or the loan principal. A fundamental and surprisingly persistent error, given that neither has ever been a taxable supply under GST. This usually stems from bundling interest into a broader billing statement without separating it clearly from taxable fee lines.

Missing the corporate guarantee valuation rule. Groups that provide intra-group guarantees without applying the 1%-of-guaranteed-value rule under Rule 28(2), often because no cash actually changed hands for the guarantee, understate a genuine GST liability that doesn't depend on whether the underlying loan was drawn.

Locking into the wrong NBFC ITC method for the year. Electing the flat 50% method without modelling whether proportionate Section 17(2) apportionment would actually yield more credit for that year, and then being unable to switch until the next financial year, is an avoidable and often costly planning failure.

Continuing cross-charge after the ISD mandate. Businesses that relied on cross-charging common head-office costs to branches before April 2025 sometimes haven't fully transitioned to mandatory ISD registration and GSTR-6 filing, which puts branch-level ITC at risk of being disallowed on review.

Assuming all insurance products are GST-exempt post-reform. The 2025 move to nil GST applies specifically to individual life and health insurance premiums. Group policies, commercial lines, and other insurance categories don't automatically carry the same exemption, and applying it broadly without checking the specific product misstates tax liability.

Getting the place of supply wrong for banking services. For most financial services, the place of supply is the location of the recipient as per the bank's records, not the branch where the transaction physically happened, which determines whether CGST/SGST or IGST applies. Multi-branch institutions that default to branch location rather than recipient records misclassify a meaningful share of their outward supply.

Falling behind on routine filing across multiple state registrations. A financial business registered in several states has correspondingly more filing obligations to keep current. GST late fees apply per registration, and persistent delays can trigger GSTIN blocking on individual state registrations. Our GST return filing guide and GST due date calendar help keep multi-state filing on track, and the Invoice Management System is useful for reconciling vendor invoices feeding into ISD credit distribution. If a notice arrives over an ITC method election or corporate guarantee valuation dispute, our GST notice reply guide explains how to respond within the deadline.

Frequently Asked Questions

Is GST charged on loan interest in India? 

No. Interest and discount on loans are exempt from GST, whether the lender is a bank or an NBFC. Only fee-based charges like processing fees, foreclosure charges, and documentation fees attract GST, typically at 18%.

What is the 50% ITC rule for NBFCs? 

Banks, financial institutions, and NBFCs engaged in lending or deposit-taking can elect to claim a flat 50% of eligible input tax credit each month instead of proportionate apportionment, but this election is locked in for the entire financial year once made.

Is ISD registration mandatory for banks with multiple branches? 

Yes, since 1 April 2025, ISD registration is mandatory (not optional) for any head office distributing input tax credit on common services to branches with different GSTINs under the same PAN.

Do I pay GST on my insurance premium? 

Individual life and health insurance premiums moved to nil GST following the September 2025 reforms. Other categories, including group and commercial insurance, may still attract GST depending on the specific product.

Is a corporate guarantee taxable even if the loan is never drawn? 

Yes. The GST value of a corporate guarantee between related parties is deemed to be 1% of the guaranteed amount per annum (or actual consideration, if higher), regardless of whether the underlying loan is disbursed.

Get Your Finance and Banking GST Compliance Right

Between the exempt-versus-fee-based distinction on every loan product, the NBFC-specific 50% ITC election that locks in for a full year, mandatory ISD registration for multi-branch credit distribution, and corporate guarantee valuation rules that apply even without cash changing hands, GST for banks and NBFCs carries more structural complexity than almost any other regulated sector.

GST Registration helps banks, NBFCs, and financial services businesses handle multi-state GST registration, ISD compliance, ITC method planning, and monthly and quarterly return filing, so credit isn't left on the table and compliance keeps pace with a multi-branch structure.
