Final answer:
To record the write-off of an uncollectible account receivable using the allowance method, the company would debit Allowance for Doubtful Accounts.
Step-by-step explanation:
When a company deems an account receivable as uncollectible, it needs to record the write-off in its books. In this case, since we use the allowance method, the company would debit Allowance for Doubtful Accounts to record the write-off. This is because the allowance for doubtful accounts is a contra asset account that represents the estimated amount of uncollectible receivables.
