Why Prior Year Adjustments Are Needed
Prior year adjustments may be identified during an audit, account reconciliation, tax review, management review, or preparation of year-end financial statements. For example, a business may discover that an expense invoice received after year-end relates to services delivered in the previous fiscal year. Another review may reveal that depreciation was calculated using an incorrect asset value or that a customer payment was applied to the wrong account.
The objective is to ensure that the accounting records reflect the correct financial position and operating results. Before entering an adjustment, the finance team should establish the reason for the correction, the amount involved, the affected accounts, and whether the prior financial statements have already been issued. Material corrections may require consultation with the company’s accountant or auditor to determine the appropriate accounting and disclosure treatment.
How to Record an Adjustment in Sage 100
The precise steps depend on the Sage 100 version, company configuration, and whether the original fiscal period remains open. In general, the finance team identifies the error, calculates the correction, selects the appropriate accounts, and records an authorized general ledger journal entry. The entry should include a clear description, supporting documentation, the effective accounting date, and the required debit and credit amounts.
If the prior period is closed, do not assume that reopening it is necessary or appropriate. Confirm the organization’s accounting policy and the guidance for the installed Sage 100 version. Some corrections may be recorded in the current period, while others may require retrospective treatment or specific financial statement disclosures under the applicable accounting framework.
After posting, review the journal entry and run the relevant general ledger and financial reports. Confirm that the debit and credit totals agree, the intended accounts changed, and the adjustment appears in the correct reporting period. Retain the original evidence, approval, calculation, and explanation so another reviewer can understand the change.
Worked Example of a Prior Year Adjustment
Assume a company discovers in the current year that $6,000 of maintenance expense relating to the previous fiscal year was omitted from its records. The company’s accountant determines that the correction should be reflected in the prior-year financial statements under the applicable accounting policy.
The proposed correcting entry would debit the relevant maintenance expense account by $6,000 and credit the appropriate payable or accrual account by $6,000, if the obligation remains outstanding. The exact treatment depends on whether the original statements have been issued and whether the correction must be handled retrospectively. The finance team should not automatically post this entry to the current year without confirming the correct accounting treatment.
Related Adjustments and Reporting Checks
Prior year corrections should be considered alongside routine Year End Adjustments, such as accruals, depreciation, inventory valuation, and revenue cut-off entries. These entries are part of the normal closing process, whereas a prior year adjustment specifically addresses a matter relating to an earlier reporting period. Expense Adjustments may be relevant when a previously omitted, misclassified, or incorrectly measured expense affects the reported results.
Use a consistent review process to verify the following:
- Identify the original transaction, error, and affected fiscal year.
- Confirm the amount using invoices, contracts, reconciliations, or other supporting records.
- Determine the appropriate accounts, accounting date, and treatment with the responsible accountant.
- Obtain the required approval and retain a clear audit trail.
- Reconcile the updated balances and review the effect on financial statements.
When the company uses an ERP alongside other finance systems, integration and reporting requirements should also be considered. The article DCAA-Compliant ERP: 2026 Buyer's Guide + AI Audit Tips discusses ERP selection and audit-readiness considerations relevant to organizations that need traceable financial records.
