What this line means
The total wages, salaries, and tips from all W-2 forms you received during the year. If you worked part-time, seasonally, or for multiple employers after age 65, add Box 1 from every W-2. This is the same line as Form 1040 line 1a — Form 1040-SR uses identical line numbers with larger print.
Does this apply to you?
- You worked a part-time or seasonal job during retirement
- You continued full-time employment past age 65
- You received W-2 wages from consulting or board service
- You earned tips reported by your employer on a W-2
- You received taxable fringe benefits included in W-2 Box 1
Easy to overlook
W-2s from short-term or early-year jobs Seniors who pick up temporary work — tax season prep, holiday retail, substitute teaching — often forget the W-2 from a two-month job. The IRS has every W-2 on file and matches them against your return. A missing W-2 triggers a CP2000 notice regardless of the amount. 1 CP2000 pattern — unreported W-2 income from short-term jobs
Taxable fringe benefits already in Box 1 Group-term life insurance coverage over $50,000 adds imputed income to your W-2 wages. Employers also include the value of personal use of a company vehicle. These amounts are already in Box 1 — do not report them a second time. 2 IRS Publication 525 — Taxable and Nontaxable Income
Watch out for this
Using W-2 Box 3 (Social Security wages) or Box 5 (Medicare wages) instead of Box 1. These boxes differ because pre-tax deductions like 401(k) contributions reduce Box 1 but not Box 3 or Box 5. Seniors still contributing to employer retirement plans see the largest discrepancies between these boxes.
