A standard Form W-2 has boxes numbered 1 through 20. U.S. Postal Workers receive Forms W-2 with boxes numbered 1 through 42.

Generally, information in boxes 21 through 42 is not needed for the calculation of income tax. An exception to this may be if you have an amount listed for Employee Business Expense on your postal worker Form W-2. These would be reported on Form 2106 Employee Business Expenses.
