If you’re self-employed, the income on your tax return is rarely the income a lender will use to qualify you for a refinance. Underwriters work from net business income after deductions, apply specific add-backs through Fannie Mae Form 1084 (the worksheet that does the heavy lifting) and average the result over 24 months. That number drives your debt-to-income ratio. Not your gross receipts.
Why Self-Employed Refinance Qualification Differs
A W-2 borrower hands the lender a paystub and a year of returns. Done. A self-employed borrower hands over two years of personal returns, two years of business returns, a year-to-date profit and loss statement and often business bank statements too. The lender then strips out every deduction taken to minimize tax, adds back only non-cash items and averages the result. Borrowers who’ve aggressively written down income for tax purposes routinely find their qualifying income runs well below their actual cash draw – sometimes by a wide margin. And that gap between book income and bankable income is the entire story.
Fannie Mae treats any borrower with 25% or more ownership in a business as self-employed under Selling Guide B3-3.2-02. That sweeps in sole proprietors, single-member LLCs, S-corp owners, partnership members and 1099 contractors. Gig workers filing Schedule C fall squarely in scope too. So this is where the generic refinance qualification primer stops applying and a different rulebook takes over.
The Two Refinance Paths
Two real paths exist in 2026. The conventional rate-and-term refinance uses Fannie Mae or Freddie Mac rules, prices at standard agency rates and lives or dies by what your tax returns show. The non-QM path – bank statement, 1099-only or P&L-only – ignores tax returns and prices the rate premium for that flexibility into the loan.
If your last two years of tax returns show stable net income that comfortably covers existing debts plus the new mortgage payment, the conventional path will be cheaper. But if your returns show heavily depressed net income from aggressive deductions, equipment depreciation or Section 179 expensing, conventional qualification will likely fail. And a bank statement loan becomes the rational choice despite the rate premium.
The Full-Doc Path: Form 1084 in Plain English
Form 1084 (Freddie Mac uses Form 91) is the cash flow analysis worksheet underwriters use to convert tax returns into qualifying income. Where you start depends on entity type. Sole proprietors start at Schedule C line 31 net profit. S-corp owners and partnership members start at K-1 ordinary business income plus W-2 wages from the business. C-corp owners start at W-2 wages with reasonable consideration of distributions.
Add-backs that increase qualifying income
Per Selling Guide B3-3.5-01, the typical add-backs are depreciation, depletion and amortization (the three non-cash deductions that never actually leave your bank account), along with business use of home and any non-recurring losses or casualty losses sitting on the return.
Items that reduce it
Personally guaranteed business debt that the borrower is on the hook for may be subtracted from cash flow if the business can’t show 12 months of payment from business funds, per B3-3.5-01. Worth knowing: the non-deductible portion of meals already sits on the return and isn’t subtracted again.
Averaging and history rules
Standard practice averages the two most recent tax years. A 12-month average is permitted only when income is clearly stable or trending upward and the lender documents the rationale. So if 2025 net income dropped meaningfully from 2024, underwriters will typically use the lower year rather than the average.
Fannie Mae requires a two-year self-employment history as the baseline. A one-year exception is possible, but only if the borrower has a documented two-year history in the same line of work as a W-2 employee at equal or higher compensation.
A Worked Example
Say a graphic designer files Schedule C showing $180,000 in gross receipts and $60,000 in net profit. Inside those expenses sit $8,000 of depreciation on equipment and a vehicle plus $2,000 of business-use-of-home deduction. Form 1084 takes the $60,000 net, adds back the $8,000 depreciation and the $2,000 home office and arrives at roughly $70,000 of qualifying annual income (about $5,833 per month). With $1,500 in monthly recurring debts and a proposed $2,200 PITI, the borrower’s DTI runs roughly 63%. That’s well above conventional limits. Yet the same borrower’s 24 months of bank deposits might support a non-QM file with no issue at all.
The Bank Statement / Non-QM Path
When tax returns won’t support qualification, bank statement loans use 12 or 24 months of deposits to estimate income. Lenders apply an expense factor to those deposits. That factor sits around 50% on business statements and lower on personal ones (it varies by lender). A CPA-prepared expense ratio may be accepted in place of the default factor.
1099-only programs total gross 1099 income and apply a smaller expense factor – often 10% to 20% – which suits contractors with low overhead. P&L-only loans rely on a CPA-prepared profit and loss statement, sometimes corroborated with two or three months of bank statements.
Non-QM bank statement refinances typically want a credit score of 660 to 700, at least 20% to 25% equity and three or more months of PITI in reserves. Larger loans push reserves to six or twelve months. And non-QM programs aren’t uniformly available in every state. Some lenders exclude specific markets under particular product lines.
The Rate Premium for Going Non-QM
Non-QM bank statement loans typically price 100 to 250 basis points above comparable conventional 30-year fixed rates as of mid-2026. That spread compresses for strong borrowers (740-plus FICO, 25%-plus equity) to roughly 50 to 75 basis points. Rates move with credit market conditions rather than the Fed funds rate, so the premium fluctuates week to week. On a $400,000 loan, a 175 bps premium tacks on roughly $470 in added monthly interest at current pricing – real money over a five-year hold. So what happens when the math doesn’t quite pencil yet? Some borrowers accept the premium for a defined holding period and refinance into a conventional loan once their tax returns recover. Buying down the rate with discount points can shorten the breakeven if you plan to hold the non-QM loan more than five years.
DTI Traps Specific to Self-Employed Borrowers
Personally guaranteed business debt counts against personal DTI unless the business has paid it from business funds for at least 12 months, per B3-3.5-01. Equipment loans on vehicles purchased and Section 179 expensed in the same year hit DTI and depress net income simultaneously, which is the worst possible combination for qualification – the deduction kills the income side while the loan payment kills the debt side. And co-mingling personal and business deposits in one checking account makes bank statement underwriting harder, because the lender has to filter transfers and non-business income out manually, line by line. Declining year-over-year income generally results in the lower year being used, with the gap sometimes flagged as a stability concern.
Documentation Checklist
Full-doc refinance: two years personal returns with all schedules, two years business returns (1120-S, 1065 or Schedule C), YTD profit and loss, YTD balance sheet for entities, business license, two months personal bank statements, current mortgage statement, homeowners insurance declarations and property tax records.
Bank statement refinance: 12 or 24 months of business or personal bank statements, business license, CPA letter if required by the lender’s overlay, two months reserves documentation, mortgage statement, homeowners insurance and tax records.
Streamline Options for Existing FHA or VA Loans
A true FHA Streamline or VA IRRRL generally doesn’t require income re-verification at all. So for self-employed borrowers who already hold a government loan and just want a lower rate without re-underwriting tax returns, these streamline products are often the cleanest path on the menu.
Improving Your Chances Before You Apply
If you know a refinance is coming in 18 to 24 months, work with your CPA to moderate aggressive deductions in the two tax years that’ll end up in the file. The planning has to happen before the returns are filed, not after the application goes in. Stop running personal expenses through the business account. And pay down revolving balances under 30% of the limit on each card 60 days before application – that single move lifts FICO and lowers DTI at the same time.
Frequently Asked Questions
How is self-employed income calculated for a mortgage refinance?
Underwriters use Fannie Mae Form 1084 (or Freddie Mac Form 91) to start with net business income from tax returns, then add back non-cash deductions like depreciation, depletion, amortization and business use of home. The result is averaged over 24 months to produce qualifying monthly income.
Can I refinance if I have only been self-employed for one year?
Possibly. But only if you’ve got a documented two-year history in the same field as a W-2 employee at equal or higher pay. Career-changers without that bridge generally need two full years of self-employment.
Do bank statement loans require tax returns?
No. Bank statement programs verify income from 12 or 24 months of deposits and skip tax return analysis entirely.
What credit score do I need for a bank statement refinance in 2026?
Most programs want 660 to 700 as a floor, with better pricing and higher LTV available at 720 and above.
How much higher are non-QM rates compared to conventional?
Roughly 100 to 250 basis points above comparable conventional as of mid-2026, compressing to 50 to 75 basis points for strong borrowers.
Will home-office or vehicle deductions hurt my mortgage qualification?
Home office and vehicle depreciation are typically added back on Form 1084 and don’t hurt qualification. Section 179 expensing, which writes off the full cost in one year, generally isn’t added back and can suppress qualifying income.
Do I need a CPA letter to refinance when self-employed?
A CPA letter isn’t universally required. Many lenders ask for one to confirm continued self-employment or to support a P&L-only file. And bank statement programs sometimes require a CPA-prepared expense ratio.
