Final answer:
The adjusting entry for the allowance for doubtful accounts reduces total assets and increases total expenses, as it accounts for estimated uncollectible receivables through the allowance method.
Step-by-step explanation:
The adjusting entry to record the allowance for doubtful accounts causes total assets to decrease and total expenses to increase if using the allowance method. When a company provides goods or services on credit, it records the revenue and the corresponding accounts receivable. Over time, some of these receivables may become uncollectible, leading to the need to estimate and record an expense for doubtful accounts. This adjusting entry is made by debiting Bad Debt Expense and crediting Allowance for Doubtful Accounts, which is a contra-asset account that reduces the total accounts receivable on the balance sheet. As a result, the entry does not immediately affect cash; it establishes an allowance to anticipate future losses from uncollectible accounts.
