Every Indian adult has a bank account. But most don't know the difference between account types — or why choosing the wrong account costs money. Here is the complete taxonomy.
1. Savings Account — The Most Common Account
What it is: A deposit account for individuals and non-commercial purposes. Earns interest on the balance maintained.
Who uses it: Salaried employees, students, pensioners, retail depositors.
Key features:
- Interest rate: 2.5–7% (varies by bank — private banks like IDFC FIRST offer higher)
- Minimum balance requirement: Varies — ₹0 to ₹10,000 (zero-balance accounts available)
- Withdrawal: No limit (unlike earlier restrictions under Section 269ST, cash withdrawals > ₹1 crore in a year attract 2% TDS)
- Interest taxable above ₹10,000/year under Section 80TTA (up to ₹10,000 exempt)
Types of savings accounts:
- Basic Savings Bank Deposit (BSBD) — zero balance, limited transactions
- Regular savings account — minimum balance required
- Premium/relationship savings account — higher balance, additional benefits
- Joint savings account — held by two or more persons, various operation modes
2. Current Account — The Business Account
What it is: A transactional account designed for businesses with high transaction volumes. No limit on number of transactions.
Who uses it: Businesses, traders, companies, professionals with high cash flow.
Key features:
- Interest: No interest paid (unlike savings account)
- Overdraft facility: Banks offer OD facilities against current accounts for businesses
- Minimum balance: Higher — typically ₹25,000–₹1,00,000
- No restriction on number of transactions per month
Why no interest? Current accounts are designed for operational liquidity, not savings. The bank uses the float (money lying in current accounts) to generate its own return.
3. NRO Account — Non-Resident Ordinary
What it is: An Indian rupee account for NRIs (Non-Resident Indians) to hold income earned in India — rental income, dividends, pension, etc.
Key features:
- Currency: Indian Rupees (INR)
- Interest: Yes, at regular savings rates
- Tax: Interest is taxable in India (TDS at 30% for NRIs)
- Repatriation: Limited — up to $1 million per financial year can be repatriated after paying applicable taxes
- Who holds: NRIs, PIOs with India-sourced income
4. NRE Account — Non-Resident External
What it is: An Indian account for NRIs to park their foreign earnings — remittances from abroad.
Key features:
- Currency: Maintained in INR but funded from foreign currency
- Interest: Yes, at regular savings rates
- Tax: Interest and principal fully exempt from Indian income tax (major advantage)
- Repatriation: Fully and freely repatriable — both principal and interest
- Forex risk: Borne by the account holder (rupee depreciation reduces the value of your INR deposit when converted back)
NRE vs NRO at a glance:
| Feature | NRO | NRE |
|---|---|---|
| Source of funds | India-earned income | Foreign income |
| Interest tax | 30% TDS | Fully exempt |
| Repatriation | Limited (up to $1M/year) | Fully repatriable |
| Purpose | Hold India income | Park foreign savings in India |
5. FCNR Account — Foreign Currency Non-Resident
What it is: A fixed deposit account held in foreign currency (USD, EUR, GBP, JPY, etc.) by NRIs.
Key features:
- Currency: Held in foreign currency — no forex risk
- Duration: 1–5 year FDs only
- Interest: Competitive with overseas rates; tax-free in India
- Repatriation: Fully repatriable
- Best for: NRIs who want to save in foreign currency without converting to INR
6. Zero-Balance Accounts: Jan Dhan and BSBD
Pradhan Mantri Jan Dhan Yojana (PMJDY): Zero-balance accounts for financially excluded Indians. Includes RuPay debit card, ₹2 lakh accident insurance, ₹30,000 life insurance. Over 50 crore accounts opened.
BSBD (Basic Savings Bank Deposit): Similar — zero balance, limited to 4 withdrawals per month including ATM.
Summary: The Account Selection Guide
| Your Situation | Best Account Type |
|---|---|
| Salaried employee, India resident | Savings Account (high-interest bank) |
| Business owner with high transactions | Current Account |
| NRI with India-sourced income | NRO Account |
| NRI parking foreign earnings in India | NRE Account |
| NRI wanting no forex risk | FCNR (fixed deposit) |
| Low-income individual, no minimum balance | Jan Dhan / BSBD |
The Smart Friend's Verdict
Your savings account is probably earning 2.7% at SBI. IDFC FIRST, Kotak, and Yes Bank offer 5–7% on the same money, same insurance cover, same access. Switch or diversify. The incremental interest on ₹5 lakh maintained balance at 5% vs 2.7% is ₹11,500/year — for zero additional effort.
