1099 Mortgage Documentation Checklist

If you are paid on 1099s, the mortgage file is closer to a small-business file than a W-2 file. The goal is a paper trail that matches: identity, income, deposits, and (when required) business existence. This is a preparation list, not a promise that any one stack will be accepted.

Gather this first

• Government ID and Social Security number (or ITIN, if that is how you file).
• Two years of personal federal tax returns, all schedules, plus IRS transcripts when the lender orders them.
• Year-to-date profit and loss if you are in a new tax year. Note whether it is CPA-prepared or self-prepared.
• Business returns if you file as an entity (S-corp, partnership) rather than a sole proprietor.
• Two months of bank statements (often more for self-employed). Large deposits need a source.
• Current contracts or offer letters that show the work is ongoing, not a one-off invoice.

Common stalls (as of 2026-08)

• Returns that do not match transcripts.
• A brand-new LLC with no operating history.
• Using gross 1099 receipts as qualifying income when the return shows much lower net.
• Co-mingled personal and business accounts with unexplained transfers.

How this connects to products

FHA and conventional can both work for documented 1099 income. The FHA vs conventional guide is about credit, down payment, and mortgage insurance, not a shortcut around tax returns. If the returns are the problem, read bank-statement loans.

Start with the income pattern on variable monthly income and the cluster hub at /learn/variable-income. If you just went 1099 last month, that is a seasoning question, not this checklist. If a partner’s W-2 is part of the story, they generally need to be a borrower: spouse W-2 offset. Partners and S-corp owners: K-1 income — what usually counts.
