Sometimes, money appears in your accounts, investments, or spending without a clear explanation. From a tax perspective, this is risky. The Income Tax law has strict rules to deal with such situations.
Sections 102 to 107 of Income Tax Act, 2025 explain what happens when you cannot properly explain your income, investments, assets, or expenses. If your explanation is missing or not convincing, the tax department can treat it as your income and tax it.
Let’s understand this step-by-step in a simple way.
Section 102 – Unexplained Credits (Cash Credit)
This section applies when money is found credited in your books (like bank account or business books), but you cannot explain where it came from.
In simple terms, if money comes into your account and you cannot prove its source, the tax department will treat it as your income.
This happens in two situations:
- You give no explanation about the source
- Your explanation is not satisfactory to the Assessing Officer
In such cases, the entire amount is taxed as your income.
Special rule for loans and borrowings
If the credit is shown as a loan, your explanation alone is not enough.
You must ensure:
- The person who gave the loan also explains their source
- The Assessing Officer is satisfied with that explanation
If this is not done, the loan will be treated as your income.
Special rule for companies (share capital, premium, etc.)
For closely held companies, stricter rules apply.
- The investor (shareholder) must explain their source
- The explanation must satisfy the Assessing Officer
Otherwise, even share capital or share premium can be treated as income.
Exception
This rule does not apply if the amount comes from:
- Venture capital fund
- Venture capital company
Many people think showing “loan from friend” is enough. It is not.
The tax department checks:
- Who gave the money
- Whether that person actually had the capacity to give it
If not, the amount becomes your taxable income.
Section 103 – Unexplained Investment
This section deals with investments that are not properly recorded or explained.
If you make an investment and:
- It is not recorded in your books, or
- The actual investment is more than what you recorded
And if you cannot explain the source properly, then that amount is treated as your income.
Example
You bought land worth ₹10 lakh but your books show only ₹6 lakh
If you cannot explain the extra ₹4 lakh, that ₹4 lakh will be taxed as your income.
People often under-report investment value to save tax or stamp duty.
But if discovered, the unexplained portion becomes taxable income.
Section 104 – Unexplained Asset
This section applies when you own assets that are not properly recorded or explained.
Assets include:
- Cash
- Jewellery
- Gold or bullion
- Virtual digital assets (like crypto)
- Any valuable item
If:
- The asset is not recorded, or
- The cost of the asset is higher than recorded
And you cannot explain the source, then its value becomes your income.
Example
You have gold worth ₹5 lakh but no record or explanation of how you purchased it.
Then ₹5 lakh is treated as your income.
During raids or scrutiny, such assets are commonly found.
If you cannot prove how you bought them (salary, savings, etc.), they are taxed as unexplained income.
Section 105 – Unexplained Expenditure
This section focuses on your spending. If you spend money but cannot explain where it came from, that spending is treated as your income.
This applies when:
- You give no explanation, or
- Your explanation is not satisfactory
Such unexplained expenditure:
- Will be treated as income
- Will not be allowed as deduction
Example
You spent ₹3 lakh on a wedding but cannot explain the source.
Then:
- ₹3 lakh becomes your income
- You cannot claim it as expense or deduction
Even if you actually spent money, tax law assumes that the source was undisclosed income.
Section 106 – Amount Borrowed or Repaid through Hundi / Improper Mode
This section targets transactions done through non-transparent methods.
If you:
- Borrow or repay money using a hundi or negotiable instrument
- Not using account payee cheque or approved mode
Then the amount is treated as your income.
It applies to both borrowing and repayment, Includes interest also.
If the amount is already taxed at the time of borrowing, it will not be taxed again when repaid.
The government wants transactions to happen through proper banking channels.
Cash-based or informal systems like hundi are discouraged.
Section 107 – Tax on Unexplained Income
This section simply tells you that all such unexplained amounts (Sections 102 to 106) will be taxed as per special tax rules.
This usually means:
- Higher tax rates
- No normal benefits or deductions
Final Understanding
All these sections follow one simple principle:
If you cannot clearly explain the source of your money, investment, asset, or spending, the tax department will assume it is your hidden income and tax it.
In real life, most problems happen because people:
- Do not maintain proper records
- Take loans without documentation
- Make cash transactions
- Under-report investments
The safest approach is simple: Keep clear records, use banking channels, and ensure every major transaction has a proper explanation.
Once you follow this, these sections will never trouble you.
