📚 What You'll Learn
The ₹5 Lakh Question That Could Cost You ₹3.9 Lakhs
Real Case: Ramesh, a small business owner in Pune, kept ₹5 lakhs in cash at home for emergencies. During an income tax survey, officers found this cash.
When he couldn't explain its source with proper documentation, he was hit with a tax demand of ₹3,90,000 (78% of ₹5L).
His mistake? Not knowing that unexplained cash attracts one of the highest tax rates in India.
This post breaks down every cash transaction rule you need to know to avoid massive penalties in 2025.
⚠️ CRITICAL: The 78% Tax on Unexplained Cash
What is Section 115BBE?
If you have cash at home (or in bank) that you cannot explain with proper income proof, the tax department can levy:
What Counts as "Unexplained"?
❌ Unexplained Cash Examples:
- • Found ₹10L at home, no income records
- • Bank deposit of ₹5L, can't show source
- • Investment in property using cash, no trail
- • Cash from "business" with no books of accounts
✅ Properly Explained Cash:
- • Withdrawal from bank (with records)
- • Gift from parents (with gift deed)
- • Sale of gold/assets (with bills)
- • Business income (with books of accounts)
How Tax Department Finds Out:
1. Cash Withdrawal Reporting (Section 285BA)
- → Banks report if you withdraw ₹20 lakh or more in a year
- → Aggregate across all accounts
- → Automatic reporting to income tax database
2. Home/Office Searches
- → Can happen during surveys or raids
- → Officers physically count cash found
- → You must explain source immediately
3. Information from Other Sources
- → Property registrar reports
- → Bank account monitoring
- → TDS/TCS data cross-matching
💰 5 Cash Transaction Rules That Can Ruin You
Rule 1: Property Sale Cash Limit (Section 269ST)
The Rule:
- • Cannot accept cash over ₹20,000 in property transactions
- • Applies to sale or purchase of immovable property
- • Even ₹20,001 triggers penalty
Penalty:
- • 100% of cash amount received
- • Example: Received ₹2L cash → Pay ₹2L penalty
- • PLUS the ₹2L is still taxable as income
💡 Real Example:
Scenario: You sold a flat for ₹50 lakhs
- • ₹45L via bank transfer (✓ OK)
- • ₹5L in cash (✗ VIOLATION)
Consequences:
- → Penalty: ₹5,00,000
- → Tax on ₹5L: ₹1,50,000 (at 30% slab)
- → Total hit: ₹6,50,000
The ₹5L cash actually costs you ₹6.5L!
✅ How to Stay Compliant:
- → Accept max ₹20,000 cash (token money)
- → Rest via cheque/NEFT/RTGS
- → Keep bank transfer receipts
Rule 2: Loan Transactions (Section 269SS)
The Rule:
- • Cannot take or repay loans of ₹20,000 or more in cash
- • Applies to all loans (friends, family, business)
- • Both taking AND repaying covered
Penalty:
- • 100% of loan amount
- • Example: ₹5L loan in cash → ₹5L penalty
💡 Real Example:
Scenario: Borrowed ₹10L from friend in cash
Consequences:
- → Penalty: ₹10,00,000
- → PLUS ₹10L loan is treated as unexplained income
- → Tax on ₹10L: ₹7,80,000 (at 78%)
- → Total damage: ₹17,80,000
Your ₹10L loan just cost you ₹17.8L!
✅ How to Stay Compliant:
- → Loan < ₹20,000? Can use cash
- → Loan ≥ ₹20,000? MUST use bank transfer
- → Create proper loan agreement
- → Keep transfer receipts
Rule 3: Business Sales (Section 269ST)
The Rule:
- • Cannot accept ₹2 lakh or more cash from one customer in one day
- • Applies to all businesses (shops, professionals, services)
- • Aggregate transactions per customer per day
Penalty:
- • 100% of cash amount received
- • PLUS expense disallowance (can't claim as business income)
💡 Real Examples:
Example 1: Jeweler
Customer buys gold worth ₹5 lakhs
- • Pays ₹3L cash (✗ VIOLATION)
- • Penalty: ₹3,00,000
Example 2: Car Dealer
Customer pays ₹10L for car
- • ₹1.5L cash + ₹8.5L cheque (✓ OK, cash < ₹2L)
Example 3: Consultant
Client pays ₹2.5L for project
- • ₹2L cash (day 1) + ₹50k cash (day 2) (✓ OK, each day < ₹2L)
✅ Smart Workaround:
- → Split payments across multiple days (genuine, not structured)
- → Accept ₹1.99L max per day
- → Rest via bank transfer
