# Suggested Diagnostics for Form 1120 Schedule M-3 – Apply Prior to e-file Submission

The answer to each test question in general should be “yes” or “true.”

The diagnostics are listed in an approximate order of importance.

The diagnostics assume that all Parts II and III column (a) and column (d) amounts are required of the taxpayer for the current tax year.

Form 8916-A is required if the taxpayer reports cost of goods sold, interest income, or interest expense.

Form 8916 is required if the taxpayer is a mixed group, that is, has a subsidiary that is a life insurance company or a property and casualty insurance company.
