There are a number of different kinds of income that get added into the wages on line 1 of your Form 1040, but do not come from W-2 box 1. Many, but not all, of these types of added wage income are indicated by an abbreviation and amount shown to the left of the total wages on line 1. Do you have an abbreviation to the left of the amount on line 1? The most common of these are the following.
- SCH - Taxable scholarship income
- HSH - Wages earned as a household employee but not reported on a W-2
- DCB - Taxable dependent care benefits from W-2 box 10
Some other types of income that might be added into line 1, without an abbreviation, are the following.
- Tips that you did not report to your employer.
- Allocated tips from W-2 box 8.
- Disability payments from a pension plan from Form 1099-R with distribution code 3 in box 7, if you are below the minimum retirement age for the plan.
- A corrective distribution or return of excess contributions from a retirement plan, from Form 1099-R with distribution code 8 in box 7.
If you have a PDF (or printed copy) of your 2019 tax return with all forms and worksheets, not just the forms for filing, look at the Wages, Salaries, & Tips Worksheet. It will show you everything that's included in line 1, and where it comes from, including all of the possibilities mentioned above.
