What should a client do if calculated accumulated depreciation doesn't match existing records when adding an asset?

When faced with a situation where the calculated accumulated depreciation does not match the existing records while adding an asset, the client should enter an adjusting entry to correct the discrepancy. This approach ensures that the accounting records accurately reflect the true state of the asset's value, providing a clear and precise depiction of its depreciation.

Using an adjusting entry allows for rectifying any mismatches without altering the initial recorded values or the asset's purchase date. This practice maintains the integrity of the financial records and ensures compliance with accounting principles. By properly adjusting the accumulated depreciation, the records align with reality, which is essential for accurate financial reporting and asset management.

The other options either lead to potential inaccuracies in the asset's valuation or do not provide a constructive way to resolve the issue. Adjusting entries are a standard practice in accounting to address inconsistencies, making this the preferable and most effective solution when discrepancies arise with accumulated depreciation.
