How do lenders calculate self-employed income?
The full answer
The standardized method is Fannie Mae's self-employed income analysis (Form 1084) or a similar worksheet. The lender takes net profit from your Schedule C or business return, restores add-backs that didn't reduce cash flow, and divides the two-year total by 24 to get monthly qualifying income.
Trend matters. If year two is higher than year one, lenders typically use the two-year average (and sometimes the higher year). If income is declining, they often use the lower year, or require an explanation — a falling trend is treated as a risk.
Non-QM loans calculate differently: a bank statement loan averages deposits and applies an expense factor; a 1099 program applies a fixed expense ratio to gross 1099s; asset-depletion divides liquid assets by the loan term. Knowing which method flatters your numbers is how you pick a loan.
What is Form 1084 and why does it matter?
It's Fannie Mae's cash-flow analysis worksheet — the form an underwriter uses to convert your tax returns into a qualifying income figure, line by line. Understanding it lets you predict your number instead of waiting to be told it.
Which year do lenders weight more heavily?
Normally a straight two-year average. But if the most recent year is lower, they use that figure alone and ask why. A rising trend gets averaged; a falling one is treated conservatively.
