1040 extraction: a line-by-line review for intake

A 1040 runs two pages: identity and income up top, then tax, credits, and payments below. Here is how to read the key lines.

What a 1040 looks like

1040 — sample layoutannotated
Filing status
Single, married filing jointly/separately, head of household, or qualifying surviving spouse — it sets your brackets and standard deduction.
Total income (Line 9)
The sum of wages, interest, dividends, business income, capital gains, and other income.
Adjusted gross income / AGI (Line 11)
Total income minus specific "above-the-line" adjustments. Many credits and phase-outs key off this number.
Deductions
Either the standard deduction or itemized deductions from Schedule A, whichever is larger.
Taxable income (Line 15)
AGI minus deductions — the amount your tax is actually calculated on.
Total tax (Line 22/24)
Your calculated tax after credits.
Payments & withholding (Line 25)
Taxes already paid via W-2/1099 withholding and estimated payments.
Refund or amount owed
If payments exceed total tax you get a refund; if not, you owe the difference.

Evaluate this workflow

For tax-document and lending intake teams

Separate income, AGI, and taxable income so a downstream reviewer can use the intended line.

Check before you accept a record

  • Confirm tax year and whether the source includes all required pages.
  • Keep line9_total_income, line11_agi, and line15_taxable_income distinct.
  • Do not infer missing schedules or treat extracted totals as a verified tax return.

An exception to hold for review

Missing supporting schedules remain missing evidence. A parsed total does not fill that gap.

Run a small evaluation

  1. Define which lines your intake process needs.
  2. Extract and compare those lines with the return.
  3. Pass reviewed values and missing-document notes to your qualified reviewer.

Record the number of files submitted, failed files, required-field corrections, and minutes spent reviewing each file. Those observations tell you whether this workflow fits your documents; a sample response does not measure extraction accuracy.

A measured synthetic extraction

On September 16, 2026 Pacific time, we sent one labeled text PDF for this document type to our production extraction service. It returned HTTP 200 in 5.10 seconds, including network time. This was a backend request, not a test of signup, payment or the complete upload interface.

1 selected field comparison differed after the production field mapping. Successful delivery does not establish extraction accuracy.

  {
    "path": "tax_year",
    "expected": 2025,
    "actual": "2025",
    "actualMissing": false
  }
]

Expected values were fixed before the run. Comparison uses exact values and types, checks the expected object fields and requires exact array lengths. A numeric string differs from a number; missing and null values differ. These easy, clearly labeled synthetic pages do not represent scanned documents, complex official forms or customer accuracy. One observation cannot establish typical latency.

Field contract correction

We replayed the same recorded response after correcting field aliases, declared tax-number types and bank last-four handling. This is an offline replay, not another extraction request. 0 selected field comparisons still differ from the original expected sample. The original benchmark stays available; unsupported distinctions and source wording are not invented to make the comparison pass.

FAQ

What does a 1040 look like?

A 1040 runs two pages: identity and income up top, then tax, credits, and payments below. Here is how to read the key lines. The annotated example above shows each region and what it contains.

Can I use this 1040 sample as a template?

Use it to understand the layout and fields. When you need the actual data off a real 1040, upload it and get structured JSON/CSV back — no manual typing.

Where do I find my AGI on a 1040?

Adjusted gross income is on Line 11 of Form 1040.

What schedules attach to a 1040?

Common ones are Schedule A (itemized deductions), B (interest/dividends), C (business), D (capital gains), and E (rental/pass-through income).
