Explain a Declining Year on a CPA P&L — The Quick Read: A down year on a CPA-prepared profit and loss statement does not automatically sink a 1099 earner’s loan file. Underwriters ask two things: has the decline stopped, and what caused it. A documented, well-supported letter of explanation paired with a strong current-year P&L usually carries more weight than the raw percentage drop.
Key Takeaways
- A single soft year rarely disqualifies a 1099 borrower — underwriters look for whether the decline has stopped and why it happened.
- Program treatment varies. There is no single federal rule for non-QM P&L files, unlike FHA’s published 20 percent threshold.
- The letter of explanation matters more than the percentage. A documented, one-time cause beats a vague or repeated slide.
- 1099 income and CPA P&L income are evaluated on different bases — gross versus net — and picking the wrong path can make the same business look weaker than it is.
- A declining personal P&L rarely blocks a separate DSCR loan on a rental property, since DSCR underwriting looks at the property’s rent, not the borrower’s tax picture.
Key Terms Defined
- CPA P&L loan: a non-QM mortgage that qualifies a self-employed borrower off a CPA-prepared profit and loss statement instead of traditional personal-income documentation.
- Letter of explanation: a written narrative, backed by documents, that tells an underwriter why income moved the way it did.
- Compilation / review: two levels of CPA-prepared financial statements. A compilation means the CPA read the numbers for reasonable form; a review adds inquiries and analysis and carries slightly more assurance. Neither is an audit.
- 4506-C / IVES: the IRS form and system lenders use to pull tax transcripts and check them against what a borrower’s P&L or 1099s claim.
- DSCR loan: a loan on a rental property that qualifies primarily on the property’s rental income covering the payment, not the borrower’s traditional personal-income documentation.
What “Declining Income” Actually Means to an Underwriter
There is no single federal rule that defines a declining-income problem for a non-QM P&L loan. Each wholesale program sets its own guideline, because these loans sit outside Fannie Mae and Freddie Mac purchase eligibility. The closest thing to a bright line comes from a different program entirely.
FHA publishes a specific threshold: a self-employment income decline over 20 percent across the analysis period forces a manual downgrade with added documentation, according to HUD Mortgagee Letter 2022-09. That is not a non-QM rule — it is a distinct program’s published cutoff, useful only as a point of contrast. Non-QM P&L underwriting does not import that number automatically. Some files with a smaller decline still draw scrutiny; some files with a bigger one still pass, if the story behind it holds up, since qualification rests on property-level rental income covering the payment, subject to lender guidelines.
Conventional trend-analysis logic offers a second contrast point. Under agency-style underwriting, when income is trending down, a lender uses the lower of the most recent year or the two-year average, not the average alone. Say a self-employed borrower’s return showed $120,000 one year and $90,000 the next — that borrower qualifies at $90,000, not the $105,000 blended number. That eliminates the instinct to average toward the better year. Non-QM P&L programs generally work differently: they tend to analyze a single current 12-month P&L window rather than blending prior years, which changes how a rough prior year gets weighted in the first place.
The Two Questions That Decide Your File
Every declining-income file, regardless of document type, comes down to two questions: has the decline stopped, and why did it happen. Documenting that income has leveled off or turned back up is a major factor in an underwriter’s read. The second question matters just as much — a one-time, non-recurring cause reads very differently than a slow multi-year slide in the same line of work.
Self-employed income moves around by nature. Year-to-year swings are common and expected for 1099 earners, which is exactly why CPA P&L programs exist in the first place. The program was built around that reality — but the underwriter still needs a reason that makes sense for this specific decline, not just an acknowledgment that self-employed income fluctuates.
Writing the Letter of Explanation That Works
The letter should pair a clear narrative with documents that back it up, not just an assertion of the story. A letter that says “business was slow” convinces nobody. A letter that shows gross revenue held steady while net income dropped because of a documented equipment purchase or a one-time expansion cost gives the underwriter something concrete to evaluate.
Strong letters usually cover:
- What happened, in plain terms — an injury, a lost client, a seasonal pattern, a planned reinvestment in the business.
- Whether the cause is likely to recur or was genuinely a one-off event.
- Supporting evidence: invoices, a client contract that ended, medical documentation, or a CPA note tying the expense to the net-income drop.
- Current-year context — a year-to-date P&L or recent deposits showing the trend has already turned.
Underwriters evaluate the quality of a decline, not just its size. A net-income dip caused by legitimate business expenses — new equipment, expansion costs, a one-time expenditure — reads very differently from a drop tied to lost customers or a shrinking client base, even if the percentage looks similar on paper.
What the CPA P&L Actually Is — And What It Isn’t
A CPA P&L is not an audit, and it doesn’t carry audit-level assurance. Preparation engagements under the applicable accounting standard, AR-C 70, let a CPA issue a financial statement without a compilation report — and that CPA doesn’t even need to be independent to do it. A required disclaimer states plainly that no assurance is provided. That’s the lightest of the three service levels; a compilation involves the CPA checking that the statements appear reasonable, and a review adds inquiries and analytical procedures for a higher, though still limited, level of assurance, as described by CPA Hall Talk.
That matters for a declining-income file because the underwriter already knows the P&L wasn’t independently verified the way an audit would be. That is exactly why the file needs a real transcript check behind it, a real CPA relationship rather than a one-time engagement, and a letter that adds context the raw numbers can’t provide on their own.
Two document rules matter here. First, borrower-prepared P&Ls are never acceptable — the statement has to come from a licensed CPA or a qualified accounting professional with an ongoing relationship to the borrower, not a spreadsheet the borrower typed up. Second, self-employed borrowers who file their own traditional personal-income documentation generally aren’t eligible for a P&L-only path at all; the CPA relationship has to be real and continuing.
Most files also carry a tax-transcript pull through the IRS Income Verification Express Service, which lets a taxpayer authorize a lender to access tax records via Form 4506-C, according to the IRS. On a P&L-only path this functions more as a fraud check than the income source itself, but underwriters still run it, and a mismatch between what’s filed and what the P&L shows is a fast way to unravel a file. That authorization is valid for four years of transcripts and stays active for 120 days after signing, per guidance referenced in Fannie Mae’s selling guide.
1099 Income vs. CPA P&L Income: Different Math, Different Story
These two documentation paths analyze different numbers, and picking the wrong one can make a decent business look worse than it is. A 1099-only program typically qualifies a borrower off gross 1099 payments received, closer to how a wage earner is evaluated. A CPA P&L program analyzes net income after CPA-adjusted business expenses.
That distinction changes how the same slowdown appears on paper. A contractor whose gross payments held roughly flat but who wrote off a large equipment purchase will look stable on a 1099 path and show a net decline on a P&L. The reverse can also happen — gross bookings can drop while margins hold, making the P&L path tell a cleaner story than the gross-income path would. Choosing the document type that matches the real story is part of the strategy, not an afterthought.
Seasoning matters here too. Most 1099 programs want a two-year history in the same line of work, including at least one year of 1099 income. A borrower who recently changed business structure has less track record to prove a rough year was temporary rather than a trend.
Where This Crosses Into a Rental Purchase
Investors who are 1099 earners often need two separate loans running at the same time — personal financing and a rental property purchase — and these two run on completely different logic. DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage.
A declining personal P&L year rarely blocks the DSCR loan on the rental side, because that loan is reviewed primarily on the property’s rental income covering the payment, subject to lender guidelines — not on the borrower’s traditional income documentation or CPA statement. On a single-family rental, that rent used for lender review typically comes from an appraiser’s Form 1007 rent schedule built on comparable rentals, and a 2-4 unit property uses Form 1025 instead; underwriting almost always defaults to the lower of the appraiser’s market rent or the actual signed lease. Anyone building out the property-side financing separately from the personal-side loan can start with Lendmire’s complete DSCR loans guide to see how that qualification path works end to end.
Where the decline does bite is the personal-side loan running alongside it — a primary-residence purchase, a refinance, or a portfolio relationship where the lender still looks at personal cash flow for reserves or credit strength. If that personal income is also propping up reserve requirements across a broader rental portfolio, one weak P&L year can shrink a lender’s confidence in the borrower’s cushion even when the DSCR file on the rental itself is fine. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Across select lenders in Lendmire’s wholesale network, personal-side files for 1099 earners typically run 12 or 24 consecutive months of bank statements, with business deposits qualified after an expense ratio — commonly 20 percent for a service business with no employees, up to 50 percent for a business with six or more employees or any product-based business, unless a CPA provides a written justification for a different figure. Transfers from the borrower’s own business into a personal account generally count in full. A P&L-based qualifying method is also available on many files, typically capped around 80 percent of qualifying deposits. Credit floors on these personal-side programs typically start around 660 to 680 depending on the program, moving to roughly 700 above the largest loan sizes, with debt-to-income up to around 50 percent and reserves that generally run three months on smaller loans and step up toward nine months or more as loan size grows — all subject to underwriting and lender guidelines, and never a guarantee of approval.
For readers weighing whether a single soft year should even be brought up proactively, Lendmire’s related coverage on how one declining year gets ended on a CPA P&L loan walks through that timing question in more depth, and the companion piece on how to qualify on a CPA P&L loan after one rough year covers the credit and documentation side.
Who This Fits — And Who It Doesn’t
This approach fits a 1099 earner whose business is fundamentally healthy but had one identifiable rough stretch — a lost client, an equipment purchase, a medical event — and whose current-year numbers already show recovery. It also fits someone with a real, ongoing CPA relationship who can produce a clean, timely P&L rather than a document assembled just for the loan.
It fits less well for a borrower on a genuine multi-year downward slide in the same line of work, since that pattern looks like a trend rather than an event, no matter how the letter is written. It also fits poorly for someone who prepares their own returns without an ongoing preparer relationship, since that borrower typically isn’t eligible for the P&L-only path at all. In either of those cases, a bank-statement path that qualifies off 12 or 24 months of actual deposits — sidestepping the declining-income question entirely — is often a stronger fit than fighting the P&L math.
This is not legal or tax advice. Loan program terms, documentation requirements, and underwriting standards change and vary by lender, and every file is reviewed individually — readers should talk with a qualified mortgage professional, and a CPA or attorney for tax and legal questions specific to their situation, before relying on any of the above.
Frequently Asked Questions
Do I need a separate CPA letter, or does the P&L cover it?
They serve different purposes. The P&L is the income document itself; a separate CPA letter or a borrower’s letter of explanation addresses why the numbers moved the way they did. Most declining-year files need both — the statement to show the numbers and the letter to explain them.
Can I still qualify if my decline is more than 20 percent?
Possibly, since that 20 percent figure is an FHA threshold, not a universal non-QM rule. Non-QM P&L programs generally weigh the reason for the decline and whether it has stopped more heavily than a single fixed percentage, though a larger decline usually invites closer review.
Should I disclose the decline before the lender finds it?
Including the letter of explanation and supporting documents with the initial submission generally moves faster through underwriting than waiting for a request, since the file arrives with the context already attached rather than surfacing as a surprise mid-review.
Is a 1099 program better than a P&L program for a down year?
It depends on whether the decline shows up in gross income or only in net income after expenses. If gross 1099 payments held up but net income dropped due to legitimate business costs, a 1099-based gross-income program may tell a cleaner story than a P&L path built on the reduced net figure.
Does a rough personal income year hurt my chances on a DSCR rental loan?
Not directly, since a DSCR loan is reviewed primarily on the rental property’s income covering the payment rather than the borrower’s personal tax picture. It can still affect other financing running alongside it, such as reserve requirements on a broader portfolio, subject to lender guidelines.
