What are GL Adjustments?
Definition
GL adjustments are accounting entries posted to the general ledger to correct, reclassify, accrue, defer, or update account balances before financial statements are finalized. They help finance teams ensure that the general ledger reflects the correct accounting period, account coding, entity, department, and reporting treatment. In practice, GL adjustments support accurate close execution, clean account balances, and reliable financial reporting.
How GL Adjustments Work
A GL adjustment usually begins when finance identifies a difference between the ledger balance and the supported accounting position. The difference may come from missing invoices, incorrect coding, timing differences, reconciliation findings, revenue timing, prepaid amortization, accrual estimates, or consolidation review.
The finance team prepares the debit and credit, attaches supporting evidence, selects the correct accounting period, routes the entry for approval, and posts it to the ledger. Once posted, the adjustment changes the financial records used for management reporting, statutory reporting, and close review.
Common Types
GL adjustments can appear across many accounting areas. The type of adjustment depends on the reason the ledger balance needs to change.
Accrual adjustments: Record expenses or revenue in the period they are incurred or earned.
Deferral adjustments: Release prepaid expenses or deferred revenue into the correct period.
Reclassification entries: Move amounts between accounts, cost centers, entities, departments, or reporting lines.
Correction entries: Fix posting errors, duplicate entries, or incorrect account coding.
Consolidation adjustments: Align entity-level balances with group reporting and elimination requirements.
Calculation Method and Example
For a correction-based GL adjustment, a useful calculation is: GL adjustment amount = Supported accounting balance - Current ledger balance. For recurring straight-line adjustments, the calculation may be: Periodic adjustment amount = Total amount ÷ Number of recognition periods.
Assume the prepaid insurance schedule shows that the correct month-end prepaid balance should be $45,000, but the current ledger balance is $50,000. GL adjustment amount = $45,000 - $50,000 = -$5,000. Finance posts an entry debiting insurance expense for $5,000 and crediting prepaid insurance for $5,000. This updates the ledger so the balance sheet reflects the correct prepaid asset and the income statement reflects the expense for the period.
Controls and Documentation
GL adjustments should be supported by clear documentation because they affect reported revenue, expenses, assets, liabilities, and equity. Each adjustment should include the business reason, calculation, source evidence, account coding, preparer, reviewer, approval date, and reversal instruction where applicable.
Strong journal entry controls help ensure each adjustment is complete, accurate, authorized, and posted to the correct period. Reviewers should confirm that the entry ties to invoices, schedules, reconciliations, contracts, management estimates, or other valid support. This strengthens balance sheet reconciliation and reduces unexplained movements during close.
Connection With Close and Reconciliation
GL adjustments are closely linked to monthly, quarterly, and annual close activities. During close, account owners review trial balance movements, subledger reports, account schedules, bank activity, revenue reports, and expense trends. If a balance does not match its support, a GL adjustment may be required.
Many adjustments come from account reconciliation work. For example, if an accrued expense account includes an old item that has already been invoiced and cleared, finance may post a correction. If a revenue schedule shows that revenue was earned but not posted, an adjustment may be needed to align recognition with accrual accounting principles.
Review and Business Use
GL adjustments help leaders trust the financial results used for decisions. Accurate adjustments improve financial reporting accuracy, cash flow analysis, profitability review, budget comparisons, and management reporting. They also help explain why ledger balances changed between periods.
Controllers often review GL adjustment activity by account, entity, preparer, amount, timing, and entry type. Recurring adjustments may indicate normal close activity, while unusual or high-value entries may require additional explanation. Clear review evidence helps finance teams support audit requests and management questions.
Best Practices
Finance teams should use standard templates, defined approval thresholds, account ownership, and close calendars for GL adjustments. Recurring entries should have approved schedules and consistent descriptions. One-time entries should explain the business event, accounting treatment, and support used.
Teams should also monitor late postings, repeated corrections, manual reclasses, aged accruals, expired prepaids, and unusual revenue adjustments. These practices improve close quality, strengthen audit readiness, and make financial results easier to explain.
Summary
GL adjustments update the general ledger so account balances reflect the correct period, classification, estimate, and reporting basis. They support accurate accruals, deferrals, reconciliations, close execution, cash flow analysis, audit readiness, and reliable financial reporting performance.
