Is Allowance for Doubtful Accounts a Debit or Credit?
Allowance for doubtful accounts is a credit. It is a contra asset that reduces accounts receivable to the amount expected to be collected, so it increases with a credit when the allowance is recorded and decreases with a debit when a specific account is written off. Its normal balance is a credit, and Schedule L reports it on its own line.

Why it works that way
Accounts receivable is an asset with a debit balance. The allowance exists to say that part of it will not be collected, so it runs the other way: a contra asset with a credit balance.
The pair is what matters. Gross receivables less the allowance equals the net the business expects to collect. Both figures stay on the books, which is why Schedule L can ask for them on separate lines.
Writing off an account records no expense
This trips people up. Under the allowance method, the expense was recognized when the allowance was created. Writing off a specific invoice later just applies the estimate: debit the allowance, credit the receivable.
Net receivables do not change and the income statement is untouched. If writing off an account reduces income, the allowance was not being used and the entry went to bad debt expense directly instead, which is the direct write off method.
The allowance is a book figure, not a deduction
Tax generally does not allow a deduction for an estimate. The deduction comes when a specific account is identified as worthless and written off.
So a company with a $4,200 allowance and $1,100 of actual write offs has a book expense of $4,200 and a tax deduction of $1,100, and the $3,100 difference belongs on Schedule M-1. The movement in the allowance year over year is what drives that adjustment, which is another reason the account has to stay visible rather than being netted into receivables.
What the balance should look like
Most firms set the allowance from the aging: a small percentage of current invoices, rising sharply for the oldest buckets. What matters is that the method is applied consistently and that the balance bears some relationship to the receivables it offsets.
Two patterns are worth a second look. An allowance that has not changed in years is not an estimate, it is a leftover, and the aging has almost certainly moved underneath it. An allowance larger than the receivables is a sign that write offs were posted to expense while the allowance was left in place, which double counts the cost.

Common questions
Is allowance for doubtful accounts a debit or credit?
A credit. It is a contra asset, so it runs opposite to accounts receivable. It is debited when a specific account is written off against it.
Does writing off a bad account reduce income?
Not under the allowance method. The expense was recognized when the allowance was set up, so the write off debits the allowance and credits the receivable with no effect on income. Only the direct write off method records an expense at the time of the write off.
Is the allowance deductible on the tax return?
Generally not. Tax requires a specific account to be identified as worthless. The book allowance and the tax write off differ, and the movement in the allowance is a Schedule M-1 adjustment.
Can the allowance be netted against receivables on Schedule L?
No. Schedule L has separate lines for receivables and the allowance, line 2a and line 2b. Netting them loses information the return asks for and removes the figure the M-1 adjustment is derived from.
