Check and print the W-2s

Step 1: Open the W-2 worksheet

In Payroll → Payroll Tax Forms click W-2 and check the year. Each row is one employee's W-2: box 1 wages, federal withholding, Social Security and Medicare tax, state withholding, and the new 2026 box 12 codes TP (tips) and TT (qualified overtime).

  1. Box 1 Wages: wages after 401(k) and Section 125 deductions.
  2. Print W-2 saves one employee's W-2 as a PDF; Print all W-2s does every employee.
  3. BSO User ID: your 8-character SSA Business Services Online user ID, written into the file.
  4. Export SSA EFW2 file (electronic W-2) saves the file to upload to SSA.

US edition: AcboBooks counts every overtime hour on a paycheck as FLSA overtime for box 12 code TT. Take out state daily or contract overtime before you file.

File electronically

Step 2: Export and check the EFW2 file

Type your BSO User ID and click Export SSA EFW2 file (electronic W-2). If an SSN, address or company detail is missing, AcboBooks lists it under Fix before filing. Check the saved file with SSA AccuWage Online, then upload it in Business Services Online.

Tip: AcboBooks has no separate W-3 printout. When you file electronically, the totals record in the EFW2 file carries the W-3 totals.
