31. Petty Cash Accounting — Controls & Process

Petty cash may appear insignificant, but it is one of the highest-risk areas in SME accounting.Weak petty cash controls lead to leakages, GST/TDS errors, audit objections, and poor financial discipline.
This guide provides a simple, controlled, and audit-ready petty cash accounting framework suitable for SMEs and growing businesses.

1. Introduction — Why Petty Cash Accounting Matters

Petty cash is used for small, day-to-day expenses such as:
  • Office refreshments
  • Courier charges
  • Local travel
  • Minor office supplies
  • Emergency repairs
Because petty cash involves physical cash, it is vulnerable to:
  • Misuse and pilferage
  • Unsupported expenses
  • Duplicate claims
  • GST ITC loss due to missing invoices
  • Lack of accountability
  • Audit red flags
A structured petty cash process protects the organisation from cash leakage and compliance risk.

2. Objective

To explain how to:
  • Maintain a petty cash system
  • Record petty cash transactions correctly
  • Implement internal controls
  • Ensure GST and TDS compliance
  • Reconcile petty cash balances
  • Pass audit scrutiny smoothly

3. What Is Petty Cash?

Petty cash is a small cash float maintained to meet minor expenses where:
  • Immediate payment is required, and
  • Bank/online payment is not practical
Petty cash is not meant for:
  • Large purchases
  • Vendor payments
  • Salary payments
  • Advances to staff (unless approved)

4. Petty Cash Systems Used in SMEs

A. Imprest System (Recommended)

A fixed amount of cash is maintained.
Example:Petty cash float = ₹10,000
At the end of the period, expenses are reimbursed to restore the float back to ₹10,000.
Advantages:• Strong control• Easy reconciliation• Audit-friendly

B. Open System (Not Recommended)

Cash is topped up randomly without reconciling expenses.
Disadvantages:• Weak controls• High misuse risk• Audit objections

5. CABTA Framework — “The 6-Step Petty Cash Accounting Process”

STEP 1 — Fix the Petty Cash Limit

Management should define:
  • Maximum petty cash float
  • Maximum amount per voucher
  • Types of expenses allowed
Example:• Petty cash float: ₹10,000• Max per voucher: ₹1,000

STEP 2 — Appoint a Petty Cash Custodian

  • One responsible person
  • Custodian is accountable for cash balance
  • Custodian cannot approve their own expenses
Segregation of duties is critical.

STEP 3 — Issue Petty Cash Vouchers

Every payment must have a voucher containing:
  • Date
  • Amount
  • Nature of expense
  • Vendor name
  • Supporting bill/invoice
  • GST details (if applicable)
  • Employee signature
  • Approval signature
No voucher = No payment.

STEP 4 — Record Transactions in Petty Cash Register

Maintain a petty cash register (manual or Excel).
Sample Register Format
This ensures transaction-level tracking.

STEP 5 — Periodic Reimbursement & Accounting Entry

At period end (weekly/monthly):
Accounting Entry:
Relevant Expense A/c Dr
To Petty Cash A/c
Then reimburse:
Petty Cash A/c Dr
To Bank A/c
Petty cash balance returns to fixed float.

STEP 6 — Periodic Physical Verification & Reconciliation

Cash on hand + vouchers = authorised float.
Differences must be investigated immediately.

6. GST & TDS Considerations in Petty Cash

GST
  • ITC allowed only if valid GST invoice is available
  • Petty cash slips without GSTIN → ITC not claimable
  • Split GST-eligible and non-eligible expenses
TDS
  • Generally not applicable due to small amounts
  • If repetitive payments to same vendor exceed limits → TDS risk arises
  • Watch out for professional fees, repairs, and contracts

7. Internal Controls for Petty Cash

Key Controls:
  • Fixed imprest limit
  • Voucher-based payments
  • Expense caps
  • Approval hierarchy
  • Surprise cash counts
  • Periodic reconciliation
  • Segregation of duties
  • Restrict cash usage where UPI is available

8. Common Petty Cash Mistakes SMEs Make

  • No vouchers
  • No custodian accountability
  • Excessive cash usage
  • Mixing personal and business expenses
  • No physical verification
  • Booking petty cash as “miscellaneous”
  • Claiming GST ITC without invoice
  • Allowing advances without tracking
These lead to audit qualifications and control weaknesses.

10. Audit & Compliance Perspective

Auditors check:
  • Petty cash register
  • Voucher quality
  • Approval controls
  • Physical cash verification
  • Reasonableness of expenses
  • GST ITC support
  • Year-end petty cash balance
Weak petty cash control is often cited as an internal control deficiency.
