See every source of income a tax return reports, and the line each one sits on
A US individual return gathers income from many places: wages from a W-2, interest and dividends from 1099s, business profit from Schedule C, gains from Schedule D, rents and partnership income from Schedule E, retirement and Social Security benefits, and other items on Schedule 1. Each source has its own line or schedule. Ask Search+ "What income sources does this return report, and where?" and open the cited lines to see each amount on the form.

How to identify income sources with Search+
- Upload the return and the income forms
Add the return with all schedules, plus the W-2s, 1099s and K-1s it was built from, whether PDFs from an employer or payer portal or scans of the paper forms. With both in one workspace, a question about a line can be answered from the return and checked against the form that reported it.
- Ask about each income type separately
Ask about wages, then interest and dividends, then business and self-employment income, then capital gains, then rental and pass-through income, then retirement income and benefits. Each type lands on a different line or schedule.
- Follow each line to its schedule and form
When an answer cites a total on the main form, ask which schedule feeds it, then which source document. Opening those citations in order shows the path from the information form to the return.
Questions to ask about income sources
List every type of income this return reports, with the line or schedule for each.
How many W-2s does the wage line appear to include, and does it match the W-2s in this workspace?
What interest, dividends and capital gains does the return report, and is Schedule B or Schedule D attached?
What gross receipts and net profit does Schedule C show, and is there a Schedule SE?
Which properties or partnerships does Schedule E list, and what income or loss does each report?
Does the return report pension, IRA distributions or Social Security benefits, and how much of each is shown as taxable?
What to look for in a return's income sources
On a Form 1040, wages, interest, dividends, retirement distributions and Social Security have their own lines; business income comes from Schedule C, capital gains from Schedule D, rental and pass-through income from Schedule E, and items such as unemployment compensation or other income from Schedule 1.
Some lines show both a total amount and a taxable amount, for example for retirement distributions and Social Security benefits. Read both columns before comparing income between years.
Schedules C and E report income after expenses, so the figure that reaches the main form is a net amount. Gross receipts are on the schedule itself.
Some income is reported on the return even when it is not taxed, such as tax-exempt interest, which has its own line. Seeing it on the return does not mean it was taxed.
Each information form, such as a W-2, 1099-INT, 1099-DIV, 1099-R or K-1, should map to a line or schedule. Missing or extra forms are the usual reason a total does not reconcile.
Ask across the return and its source forms together, or narrow a question to the return alone; citations show which document each figure came from.

What are income sources on a tax return?
Income sources are the categories of income a return reports, such as wages, interest, dividends, business profit, capital gains, rents, retirement distributions and benefits, each placed on a designated line or supporting schedule.
