The Complete Guide to Prepayment Amortization for Finance Teams
Learn how to correctly record, track, and amortize prepaid expenses so your balance sheet is always accurate — without Excel.
When a deposit is a prepaid expense, when it is a financial asset, and how to account for refundable versus non-refundable deposits — with journal entries for each scenario.
Deposits, retainers, and security payments are frequently miscoded in the accounts — sometimes as prepaid expenses, sometimes as current assets, sometimes directly to expense. The correct treatment depends on whether the deposit is refundable, what it is paid for, and whether it represents a right to future goods or services.
A refundable security deposit — such as a lease deposit or utility deposit — is not an expense at all. It is a financial asset: you have a right to receive cash in the future. It should be recorded as "Security Deposits" or "Deposits Receivable" in the non-current or current assets section of the balance sheet, depending on whether you expect to recover it within 12 months.
Common error: coding a £5,000 lease deposit to "Prepaid Expenses" or directly to Rent Expense. It is neither — it is a financial asset that should stay on the balance sheet until the deposit is returned or forfeited.
If you pay a deposit upfront as part of a contract to receive goods or services — a deposit on a custom piece of equipment, or an upfront payment to a supplier — this is a prepaid asset. You have paid in advance for something you will receive later. Record it as a prepaid expense or advance payment on the balance sheet.
The prepaid asset is recognised as an expense when the goods are delivered or the services are performed. For a deposit on equipment, you might reclassify it to fixed assets once the equipment is delivered.
A retainer paid to a law firm, accountancy practice, or consultant is generally a prepaid expense — you are paying upfront for a defined amount of future service. The retainer is amortised as the services are rendered. If the retainer is refundable for unused portions, the unearned element remains as a current asset until consumed or returned.
When paid: Debit Deposits Receivable (non-current asset), Credit Bank. When the deposit is returned: Debit Bank, Credit Deposits Receivable. If the deposit is forfeited: Debit the relevant expense account (e.g., Property Costs), Credit Deposits Receivable.
When paid: Debit Prepayments (current asset), Credit Bank. When goods/services are received: Debit the relevant expense or asset account, Credit Prepayments.
If a refundable deposit is only partially returned (for example, a landlord deducts for repairs), split the journal: the returned portion is a receipt to cash, and the deducted portion is charged to the appropriate expense account (Property Costs, Repairs and Maintenance). Do not net the two — show both sides clearly for audit purposes.
Under FRS 102, deposits that give rise to a financial asset (i.e., a contractual right to receive cash) should be recognised at their transaction price and subsequently held at amortised cost. For most small businesses, this simply means keeping them at the amount paid unless there is evidence of impairment.
