1. Yes, you can lend money to your wife at 4-5%, but the tax consequences are not what most people expect. The main issue is not scrutiny because of the low interest rate; it is the clubbing provisions under the Income-tax law.
Your proposed structure
- Husband (55): Rs. 3 crore in bank/FDs, no salary/business income.
- Wife (50): Homemaker, no income.
- Husband lends Rs. 2 crore to wife @ 4%.
- Wife invests Rs. 2 crore in FD @ 7%.
- Husband invests Rs. 90 lakh in an arbitrage fund (>3 years) and keeps Rs. 10 lakh for expenses.
Will 4% interest invite scrutiny?
By itself, no.
There is no provision requiring loans between spouses to be at market interest merely because they are relatives.
A 4% or even 0% loan is legally possible if:
- it is a genuine loan,
- there is a written loan agreement,
- interest is actually paid,
- bank trail exists,
- repayment terms exist.
So 4% is not automatically suspicious.
However...
The much bigger issue: Clubbing of income
Under the clubbing provisions, if an individual transfers an asset to the spouse without adequate consideration, the income arising from that transferred asset is clubbed back in the transferor's income.
A loan is generally considered consideration only if it is genuine and enforceable.
However, when a spouse receives funds at a concessional rate (4% when commercial deposits earn about 7%), the tax department could argue that:
- part of the economic benefit is effectively a transfer,
- especially where the sole purpose is income splitting.
Although there is no specific rule saying interest must equal market rate, a below-market loan creates a more debatable position than a market-rate loan.
More important practical issue
Suppose:
FD return = 7%
Loan interest = 4%
Spread = 3%
Husband
Interest received = Rs. 8 lakh
Wife
Interest earned = Rs. 14 lakh
Interest paid = Rs. 8 lakh
Net income = Rs. 6 lakh
If the Assessing Officer concludes that clubbing applies, the FD interest (or at least the income attributable to the transferred funds) may still be clubbed in the husband's hands, defeating the objective.
So the tax benefit becomes uncertain.
Litigation risk assessment
Structure | Litigation risk |
Gift to wife FD | Very High (clear clubbing) |
Interest-free loan | High |
Loan @ 4% | Moderate |
Loan @ prevailing market FD rate (6.75-7%) | Low |
Commercial documented loan with repayments | Lowest |
