Account 515 records the movements of funds between an entity and the public treasury or public establishments with financial autonomy. Attached to class 5 of the General Chart of Accounts, it functions as a mirror of account 512, but is reserved for relations with public organizations. Mastering it is essential for accurately reading cash flow in local authorities and entities subject to public accounting.
Account 515 and M57 nomenclature: what changes in cash flow monitoring
The generalization of budgetary and accounting instruction M57 as a reference for most local authorities modifies how account 515 interacts with other cash accounts. Under M57, account 515 remains the pivot for monitoring public liquidity, but its reading must incorporate finer subdivisions related to attachment operations and cross-flows between supplementary budgets.
We observe that this evolution pushes financial services to review their internal chart of accounts. Where M14 allowed for a relatively linear tracking of the balance at the treasury, M57 requires a more rigorous distinction between order operations and actual operations passing through 515. A monthly reconciliation between the public accountant’s statement and the balance of account 515 in the authorizing officer’s records becomes a practice to be systematized.
As detailed in the explanation of account 515 on Smart ‘n Skilled, each account opened with the treasury or a public establishment justifies a distinct subdivision of 515, with no possible compensation between credit and debit balances.
Degraded balance of account 515 despite a positive working capital
A comfortable working capital does not guarantee an exploitable balance of account 515. This situation, long considered marginal, is becoming common in local authorities. Delays in grant payments (State, region, department) and payment delays from users widen the gap between the accounting wealth of the authority and its actual capacity to pay its suppliers.
An account 515 in the red blocks the payment of mandates, even if the voted budget is surplus. The public accountant refuses to execute expenditures as long as the available balance at the treasury does not cover the presented mandates. The authority then finds itself in an operational deadlock that a mere examination of the working capital cannot anticipate.
Cash flow delays and risk management
We recommend monitoring the balance of account 515 on a weekly basis, cross-referencing three indicators:
- The amount of mandates issued but not yet paid by the accountant, which represents the immediate pressure on the available balance.
- Receipts issued but not collected, the average collection period of which conditions the pace of replenishing 515.
- The projected schedule for disbursement of notified grants, the only reliable lever for anticipating significant cash inflows.
This parallel monitoring allows for triggering, if necessary, a cash line before a blockage occurs.
Cash placement and constraints on account 515
Article L.1618-2 of the General Code of Local Authorities strictly regulates the possibilities for investing public funds. Authorities can only invest their cash in secure products, and any investment operation passes through account 515 before being allocated to investment securities accounts (class 50).
The validation procedures by the public accountant have been strengthened. The goal is to prevent an authority from immobilizing funds in unsuitable supports while its balance at the treasury risks falling below the threshold for covering current expenses. In practice, the accountant checks that the proposed investment does not jeopardize the liquidity of account 515.
Typical entries during an investment
When an authority invests a cash surplus, the accounting scheme debits an account from class 50 (for example, 506 for bonds) and credits 515. The return of funds at maturity reverses the movement. No compensation between the investment and the current balance of 515 is allowed: the two lines remain distinct on the balance sheet.
This rigor in presentation prevents masking a tense cash situation behind a portfolio of securities whose actual liquidity may vary.
Accounting reconciliation of account 515: method and common errors
The reconciliation between the balance of account 515 in the authorizing officer’s accounting and the statement from the public accountant is equivalent to bank reconciliation for a private company. The discrepancies arise from three recurring sources.
The first is the temporal gap between the issuance of the mandate and its execution. A mandate issued on the 28th of the month may only be cashed on the 3rd of the following month. This delay, variable depending on the treasuries, distorts the reading of the balance if one relies solely on the general ledger.
The second source of discrepancy concerns budgetary order operations. Certain entries modify the apparent balance of 515 in the accounts of the authorizing officer without any real movement of funds at the treasury. We observe that this confusion is common during the attachment of expenses and revenues at the end of the fiscal year.
The third source is the erroneous allocation of a movement on 515 instead of 5151 or 5159 (specific subdivisions). A poorly configured nomenclature in the accounting software generates discrepancies that only a line-by-line check can identify.
Frequency and formalization of reconciliation
A documented monthly reconciliation protects against cumulative errors that only reveal themselves in the management account. The reconciliation document must list each pending operation, its amount, and its expected regularization date. This formality, sometimes neglected in small municipalities, is nevertheless the first line of defense against cash anomalies.
Account 515 is not a simple passive receptacle for public financial flows. Its active management, articulated with the monitoring of working capital and the grant schedule, determines an authority’s ability to meet its commitments without resorting to costly cash lines.
