# employment_income # employment_income The link between an employment record, the income it produced, and the document that evidenced it. Employment_income describes properties related to income received from employment. ## Why it matters Three-way rather than two-way, and the third leg is the point. An income figure is attributable to an employment, and it was evidenced by something — a paystub, a tax form, a verification response — and the record of which document supported which figure is what an underwriter needs when a file is questioned. Holding the evidence on the relationship rather than on the income record keeps the same income figure usable when a second document corroborates it. Two documents supporting one figure is two of these, not a document field overwritten. ## In practice Employment writes these as it normalises a vendor response, which is why a returned income figure can always be traced back to the employer and the artifact it came from. ## Relationships | Property | Points at | Definition | | --- | --- | --- | | `has_document` | `document` | An income document is a document that provides information about an individual's income.
