The Phantom Income Report: What 31 Million Tax Returns Reveal About Self-Employed Mortgage Income

A self-employed borrower and a salaried borrower can earn the exact same living and walk into a mortgage office with wildly different odds of approval. The salaried applicant hands over a W-2 and a pay stub, and the number a lender counts is the number on the page. The self-employed applicant hands over tax returns — and watches the income a lender will count shrink, sometimes by more than half, before the conversation even starts.

That gap has a cause that is rarely explained to the people it affects most. To cut their tax bill, self-employed Americans deduct aggressively and legally — and every deduction that lowers taxable income also lowers the qualifying income an underwriter uses. Accountants optimize for April. Mortgage underwriting reads the same return in the opposite direction. We call the difference phantom income: money you genuinely earned that has vanished from the only figure the lender cares about.

To measure it, we went to the most authoritative source that exists — the IRS's own Statistics of Income tabulations of every nonfarm sole proprietorship return filed for tax year 2023: 31,125,909 returns reporting roughly $2.06 trillion in gross receipts. Here is what those returns reveal about how much income the self-employed actually lose at the mortgage table — and, more usefully, how much of it the right loan can win back.

Finding 1: Only 18¢ of every dollar reaches the bottom line

Start with the headline. Sole proprietors took in about $2.06 trillion in gross business receipts in 2023 and reported roughly $377 billion in net income after deductions — across all returns, including those that reported a loss, that is 18¢ of countable income for every gross dollar earned.

A lender does not get to use your gross receipts. Fannie Mae and Freddie Mac both start self-employed qualifying income at the net profit on Schedule C, line 31 — then make a handful of adjustments we will get to shortly. So the spread between what you bring in and what you net is, for mortgage purposes, the spread between the business you run and the borrower you appear to be.

That spread is not uniform. It is brutal in high-revenue, thin-margin trades and far gentler in service businesses with few hard costs. The table below ranks recognizable trades by how many cents of net income — the income a lender counts — survive per dollar of gross receipts, among profitable sole proprietors in each field.

Read the top of that list carefully, because it is counterintuitive. A profitable retail sole proprietor grosses more than $130,000 on average but nets about $18,000 — 14¢ on the dollar. A self-employed trucker grosses nearly $148,000 and nets about $27,000. These are not failing businesses; they are normal businesses with real costs. But to an underwriter reading only line 31, a six-figure operation can look like a part-time job.

At the other end, a professional consultant or a self-employed clinician keeps a far larger share of every dollar — there is simply less "business" between the revenue and the take-home. The lesson is not that one trade is better than another. It is that the income a lender counts is a function of your industry's cost structure as much as your success — and that the borrowers who look weakest on paper are often running the largest operations.

Finding 2: Most of the gap is real — but a large slice is "phantom"

It would be dishonest to call that entire 18¢-on-the-dollar compression phantom income. Most of it is genuine cost: inventory, materials, fuel, subcontractors, rent, payroll. That money truly left the business, and it is right that a lender does not count it.

But a meaningful, recoverable slice never left the business at all. These are the non-cash deductions — paper expenses that lower taxable income without lowering the cash in your account:

• Depreciation. The yearly write-down of equipment, vehicles, and property you already bought. It is a deduction on the return, but no money goes out the door for it this year.
• Depletion. The equivalent write-down for extractive and natural-resource businesses.
• Business use of home. The home-office deduction — a share of rent or mortgage, utilities, and upkeep you were paying anyway.

Mortgage underwriting knows this. Fannie Mae's cash-flow analysis (Form 1084) and Freddie Mac's Form 91 both add these non-cash items back to net profit when calculating qualifying income — precisely because they reduced your taxes without reducing your cash flow. Across all sole proprietors in 2023, depreciation alone was about $79 billion — enough to lift countable income by roughly 21%. Add depletion and the home-office deduction and the recoverable total is about $95 billion, or 25% of net income.

That is the phantom income. It is sitting on the return of nearly every self-employed borrower, and whether it gets counted depends entirely on whether the loan and the loan officer know to look for it.

Finding 3: The trades that look worst hide the most

Here is where the data turns from discouraging to useful. The non-cash add-backs are not spread evenly — they concentrate in capital-intensive trades, the same trades that looked weakest in Finding 1. The businesses with the most equipment, vehicles, and property to depreciate are exactly the ones whose net income understates their real cash flow the most.

The table below shows how much each trade's countable income rises when depreciation is added back, as the agencies' own forms instruct.

Line the two tables up and the pattern is unmistakable. Trucking, transportation, taxi-and-rideshare, agriculture, manufacturing — the trades sitting near the bottom of the "cents on the dollar" ranking are sitting near the top of the add-back ranking. (Agriculture's figure is extreme because its net income, after widespread losses, is so thin relative to its depreciation; the underlying point — heavy equipment, large write-downs — is the same.) Meanwhile the service trades that keep the most net income — consultants, clinicians, finance professionals — have the least to add back, because they had little to depreciate in the first place.

In other words: the worse your return looks to a lazy underwriter, the more recoverable income it probably contains. The borrowers most likely to be wrongly turned away are also the ones with the most to gain from a lender who reads the whole return.

What the gap costs at the closing table

Translate the phantom income into the only currency that matters for a home purchase — borrowing power.

Take the average profitable sole proprietor: about $24,790 in net income, or roughly $2,066 a month, before any add-back. Now add back depreciation at the average rate (about 21%). Nothing about this borrower's life has changed — same business, same bank account, same return. Only the income figure the lender uses has changed.

How to win back your phantom income

The phantom income is real, it is recoverable, and the path to recovering it is specific. Four moves do most of the work:

1. Make the add-backs explicit. Before you apply, identify every non-cash deduction on your last two returns — depreciation, depletion, business use of home, and any one-time losses. These are the dollars an underwriter can add back to your net profit. Our guide to mortgage add-backs walks through each one, and the income-calculation pillar shows how the full Form 1084 math comes together.
2. Consider a program built for your return. When two years of tax returns still understate your cash flow, a bank-statement loan qualifies you on deposits instead of net profit — often the single biggest fix for a heavily-deducted borrower. See what your deposits could support with the bank-statement income calculator.
3. Don't over-optimize the year before you buy. The same aggressive deductions that win in April can cost you a house in the spring. If a purchase is on the horizon, the deductions-vs-qualifying tradeoff is worth planning around with your CPA.
4. Work with a lender who reads the whole return. The add-backs only happen if someone applies them. The difference between Finding 1 and Finding 3 is, very often, just the loan officer.

Methodology and sources

Data. Figures are our own calculations from the Internal Revenue Service, Statistics of Income (SOI), Nonfarm Sole Proprietorship Statistics, Tax Year 2023 — Table 1 (selected income-statement items by industry) and Table 2 (the detailed national income statement). The universe is all 31,125,909 nonfarm sole-proprietor returns (Schedule C); 21,411,462 (69%) reported net income.

Definitions. "Cents on the dollar" is net income divided by gross business receipts. The headline 18¢ figure uses net income less deficit across all returns (it nets out reported losses); the by-trade income table uses averages among profitable returns only, so the two are not directly comparable and are labeled accordingly. The "income restored by the depreciation add-back" is each industry's depreciation deduction expressed as a share of its net income less deficit — which is why capital-intensive, loss-prone sectors (agriculture especially) show very large percentages.

Add-backs. Treating depreciation, depletion, and business-use-of-home as additions to qualifying income follows Fannie Mae's Form 1084 cash-flow analysis and Freddie Mac's Form 91; see Fannie Mae Selling Guide B3-3.6-03 and Freddie Mac Guide 5304.1. Actual qualifying income also nets out non-recurring income and meals adjustments, which we do not model here.

Mortgage illustration. Borrowing-power figures use Freddie Mac's Primary Mortgage Market Survey 30-year average for the week of June 11, 2026 (6.52%), a 28% housing-to-income ratio, no other monthly debts, and exclude taxes and insurance. They are illustrative, not a quote or an offer.
