The return stack is still the engine. [Home](/)[Learn](/learn/)CreditCredit Educational [← Mortgage learning hub](/learn/) On most conventional and FHA self-employed files, signed tax returns and IRS transcripts are what actually move the income calculation. A CPA letter can support that stack. It does not replace it. Snapshot as of 2026-08. This is not tax advice. On agency (Fannie Mae, Freddie Mac, and many FHA) self-employed files, signed tax returns and IRS transcripts are what usually move the income calc. A CPA letter is supporting documentation. It does not replace the return stack. ## Returns vs letter What typically moves an agency self-employed file as of 2026-08.Question[Tax returns + transcripts](/blog/two-years-of-tax-returns-vs-one-year-mortgage/)CPA letter / YTD P&L What usually moves agency incomeOn agency (Fannie Mae, Freddie Mac, and many FHA) self-employed files, signed tax returns and IRS transcripts are what usually move the income calc. A CPA letter is supporting documentation. It does not replace the return stack.A CPA-prepared year-to-date profit and loss, and a letter confirming the business exists and the borrower is self-employed in that line of work, can support a file that already has returns. That is common while the current year is still open. What it cannot doA missing year is still a missing year. Some overlays allow one year in the same line of work — that is not a CPA shortcut.A letter that states an annual income number without matching returns, transcripts, and a paper trail of deposits is typically not a qualifying method on an agency file. It is not a substitute for two years of returns, and it does not turn last month’s first 1099 into a history. Overlays differ. A loan officer still applies the guide in force for the product. ## Where a CPA package is useful - Year-to-date profit and loss while the current year is still open. - Confirmation that the business exists and you are self-employed in that line of work. - Support for a [one-year overlay conversation](/blog/two-years-of-tax-returns-vs-one-year-mortgage/) — next to a full year of filed returns, not instead of them. Some lender overlays allow a shorter history when the borrower has a documented track record in the same occupation as a W-2 employee, a complete year of returns, year-to-date profit and loss, and strong compensating factors. That is an overlay, not a published right. K-1 income is still taken from the K-1 and matching returns, not from a CPA summary of distributions. See K-1: what usually counts. Deep guide: [K-1 income](/blog/k-1-income-what-usually-counts/). ## Where it stalls the file - “My CPA says I make $X” with no matching 1040, K-1, or transcripts. Underwriters are not collecting testimonials. - Using a letter to paper over [a 1099 job that started last month](/blog/just-went-1099-last-month/). Last month’s first invoice is still not a history. - Co-mingled deposits that the P&L cannot explain: [business vs personal co-mingling](/blog/business-vs-personal-bank-co-mingling/). ## If write-offs crush taxable income Some Non-QM overlays weigh CPA letters and P&Ls more heavily, still next to bank statements or assets. That is an investor overlay, not a reason to skip transcripts on an agency file. Start with [bank-statement loans](/blog/bank-statement-loans-when-tax-returns-undercount-income/) and the [Non-QM hub](/learn/non-qm/) — not a stronger letterhead. ## What happens next - Gather two years of personal (and business) returns plus transcripts even if you hope a letter helps. - Use the [income calculator](/calculators/income/) with a documented average, not the CPA’s round number. - Map: [variable income hub](/learn/variable-income/).
