Is lending money with interest illegal in India? No, charging interest is legal, but lending as a business needs a state money-lender licence, courts can reopen interest that’s unconscionable, and cash loans of ₹20,000 or more breach the Income Tax Act. This is general information, not legal advice.

The Short Answer
The law regulates how you lend, not whether you can charge interest.
- India has no dedicated statute for loan agreements, so they’re governed by the Indian Contract Act, 1872, supplemented by state money-lending laws, the Usurious Loans Act, 1918 and tax rules
- Interest is allowed, and registered money lenders can charge it within state limits and recover debts through legal means
- The risk comes from licensing, excessive rates and how the money moves
Lending as a Business Needs a Licence
State Money Lenders Acts draw a line at business activity.
- Each state has its own act, and they apply to people who carry on the business of money lending
- Lending to a friend or relative generally doesn’t need a licence, according to several guides
- A Calcutta High Court decision cited in one guide says the Bengal Money Lenders Act applies only to those in the business of money lending, not to isolated transactions
- Habitual lending to many people at interest can cross into business, and one guide says doing it as “side income” without a licence is illegal
- In Maharashtra, lending without a licence carries imprisonment up to two years and a fine up to ₹50,000, according to one guide to the 2014 Act
- No guide gives a bright-line test for when casual lending becomes business, so it’s a judgement
Interest Rate Limits
There’s no single national cap.
- Several states cap rates, and the cap is often set by state government notification
- Charging above the state cap can invalidate the agreement or lead to penalties, according to one guide
- Under the Usurious Loans Act, 1918, a court can reopen a transaction where interest is excessive and the deal is substantially unfair, and relieve the borrower of the excess
- Pick a rate that’s reasonable and defensible, and check your state’s rules
Cash Loans of ₹20,000 or More
The tax law restricts how the money changes hands.
- Section 269SS prohibits accepting a loan or deposit of ₹20,000 or more in cash
- Section 271D imposes a penalty equal to the amount accepted
- The penalty falls on the person accepting the loan, so a ₹50,000 cash loan to a cousin could cost the borrower ₹50,000, according to one guide
- A violation doesn’t by itself make the loan void, but cash loans without proof can be hard to enforce
- Use a cheque, draft or electronic transfer for amounts above the limit
Documentation
Paper trail protects both sides.
- Write a loan agreement with principal, interest rate, tenure, repayment schedule and default terms
- Registration isn’t mandatory for a friendly loan, but one guide recommends it for larger amounts
- Keep bank records of the transfer and every repayment
- A promissory note can also support the claim
Tax
Interest is income.
- Interest you earn is declared under “Income from Other Sources”
- Large cash transactions can draw scrutiny
- Tax rules and thresholds change, so confirm with a chartered accountant
Banks and NBFCs Are Different
Institutions follow another rulebook.
- Banks are regulated under banking laws by the RBI and are exempt from state money-lending laws
- Registered money lenders and NBFCs also have legal authority to lend, under their own regimes
- If you plan to lend regularly, look at which regime fits, instead of lending informally
