Tailored for JKSSB Accounts Assistant (Finance) & similar competitive exams.
1. Cash Book
1.1 What is a Cash Book?
A Cash Book is a subsidiary book that records all cash and bank transactions in chronological order.
- Dual Function: It acts as both a journal (book of original entry) and a ledger (for cash and bank accounts).
- Purpose: It eliminates separate ledgers for cash/bank, provides an instant balance, and reduces posting errors.
1.2 Key Features
| Feature | Explanation |
|---|---|
| Chronological Entry | Transactions are recorded date-wise. |
| Two-Sided | Debit side for receipts; Credit side for payments. |
| Balance Carried Down (c/d) | Shows the cash/bank balance at the period end. |
| No Narration Required | The nature of the entry is evident from the side it’s on. |
| Posted Directly to Ledger | Cash & bank accounts are updated from here; other accounts are posted from the journal. |
1.3 Types of Cash Book
| Type | Columns | When to Use | Typical Entries |
|---|---|---|---|
| Single Column | 1 (Cash) | Small businesses with only cash transactions. | Cash receipts & payments. |
| Double Column | 2 (Cash & Bank) | Most businesses with frequent cash and bank transactions. | Cash/bank receipts and payments. |
| Triple Column | 3 (Cash, Bank, Discount) | Firms that regularly allow/receive cash discounts. | Includes Discount Allowed (debit) and Discount Received (credit). |
| Petty Cash Book | Analytical (multiple expense columns) | For small, repetitive expenses (e.g., stationery, conveyance). | Operates on an imprest system (fixed float, reimbursed when low). |
Mnemonic: “Silly Dogs Try Playing” – Single, Double, Triple, Petty.
1.4 Posting from Cash Book to Ledger
- Cash/Bank columns → Post to Cash Account and Bank Account.
- Discount columns → Post to Discount Allowed A/c (Dr) and Discount Received A/c (Cr).
- Other accounts (Sales, Purchases, etc.) → Post from the journal, not the cash book.
1.5 Bank Reconciliation Statement (BRS)
Purpose: To explain differences between the cash book’s bank balance and the bank statement balance.
Common Causes:
- Outstanding cheques (issued but not cleared).
- Deposits in transit (recorded but not yet credited by the bank).
- Bank charges/interest not yet entered.
- Errors (omission, wrong amount, wrong side).
Mnemonic for Adjustments: “O.D.D. – E” – Outstanding cheques (add to cash book), Deposits in transit (deduct), Debit/credit errors (adjust), Errors of omission/commission.
1.6 Petty Cash Book – Imprest System
- Imprest Amount: A fixed float (e.g., ₹5,000) given to the petty cashier.
- Recording: Expenses are recorded in analytical columns.
- Reimbursement: At period end, total expenses are reimbursed to restore the original float.
- Advantages: Controls small expenses, reduces cash book entries, and aids audit.
