1088 Tax Form PDF Details

The 1088 form, also called the Fannie Mae Comparative Income Analysis, is a standardized mortgage worksheet that lenders use to evaluate whether a self-employed borrower's business generates stable enough income to support a home loan. It compares financial data across two consecutive years, tracking gross income trends, operating expense changes, and net taxable income to build a picture of business viability.

Depending on business structure, the form draws data from different IRS filings:

Lenders calculate percentage changes in gross income, total expenses, and taxable income for each reported year. A steady or growing income trend across both years typically strengthens a borrower's loan application. Sharp declines may require additional documentation. Related Fannie Mae forms include Fannie Mae Form 1084 for cash flow analysis and the Fannie Mae Income Worksheet. Self-employed borrowers may also need the self-employed income analysis form.
