IDs on W-2s

SSNS

Not available

A W-2 is a tax form that reports wages and withholdings, and one key piece of information it includes is an employee’s Social Security number. The clue "IDs on W-2s" is asking for the abbreviation of those identification numbers, which are commonly called SSNs. It’s a straightforward definition with no wordplay—just a direct reference to what you’d find on that tax document. The answer is plural ("SSNS") because the clue implies multiple IDs, like those listed for employees on a batch of W-2s.
