How is commission income usually reviewed?
Commission income is usually reviewed over a documented history and compared with current year-to-date earnings. The underwriter evaluates stability, trend, frequency, employer verification, and whether the income can reasonably continue.
What if commission income changes each month?
Monthly changes are expected in many commission roles, so the analysis generally uses a supported average rather than the highest month. A declining pattern or a material compensation change can require more explanation and documentation.
Which documents help support commission income?
Useful records can include pay statements, W-2 forms, employment verification, commission agreements, year-to-date totals, and tax returns when required. The exact package depends on the program and how the income is reported.
- Recent pay statements
- W-2 forms
- Written employment verification
- Compensation or commission plan
- Documentation of recent job or structure changes
What if the borrower recently changed employers?
A recent employer change does not automatically prevent qualification, but the reviewer must understand continuity of occupation, compensation structure, fixed versus variable income, and available history. A new draw, recoverable advance, or changed commission plan can affect the calculation.
Frequently asked questions
Questions borrowers ask about self-employed and alternative income
Can the best commission month be annualized?
Generally, a single strong month does not establish stable annual income. The documented history and current trend are more important.
Does base salary count separately?
Eligible base pay may be calculated separately from variable commission income, with each component documented under the program.
Can declining commission income qualify?
It may require a conservative calculation or may not be usable if the decline is not stabilized. The facts and current guidance control.
Are unreimbursed job expenses deducted?
Treatment can depend on the program and current tax and underwriting guidance. Have the complete file reviewed rather than relying on an old rule.
