Do I have to track prepaid expenses this precisely?

Not necessarily. Many small, cash-basis businesses simply expense a prepayment in full when it is paid. Spreading it out matters more once the amount is large enough to distort a specific month.

Is a security deposit a prepaid expense?

Not really — a deposit is refundable and never gets consumed the way a prepaid premium does. This chart does not have a separate account for it, so it often ends up here as the closest fit; flag it in a memo so it is not mistaken for a real prepaid cost.

1400 — Prepaid Expenses

Pay a full year of insurance in one lump sum in January, and you have not incurred twelve months of expense that day — you have bought a benefit stretching across the rest of the year. That gap is exactly what account 1400 is for.

Prepaid Expenses is an asset with a normal debit balance: the upfront payment debits this account rather than immediately hitting an expense line in full. As each covered period passes, a portion moves out of this account and into the real expense account it belongs to — insurance expense recognized month by month, for example, rather than all at once on the day it was paid.

For many small businesses this level of precision is more than the books need — expensing a prepaid item in full when paid is common and fine for cash-basis bookkeeping. It matters more once a prepayment is large enough to distort a given month's profit, worth a conversation with an accountant if unsure.

What belongs here

an annual insurance premium paid in one payment upfront
rent paid several months in advance in a single payment
a prepaid annual software or service contract paid once for the full year
a retainer paid to an attorney before the work covered by it has been done

What does not belong here

a payment that covers only the current period — that goes straight to the matching expense account (Insurance, Rent, Software & Subscriptions) with nothing prepaid about it
a deposit toward inventory or job materials — that belongs in Materials (5200) or Cost of Goods Sold (5000), not here
a refundable security deposit — strictly speaking that is a different kind of asset than a prepaid expense, since it is never consumed the way a prepaid insurance premium is; this chart does not have a dedicated deposit account, so it is the closest available bucket
anything already fully used up by the time you record it

Where it shows up

Shows on the balance sheet as a current asset. It should shrink steadily over the period it covers as the assistant moves recognized amounts into the matching expense account.
