How Lenders Analyze Your Form 1040 Income
When you're self-employed, your lender can't just look at the bottom line of your tax return and call it your qualifying income. They need to examine each line item on your Form 1040 to separate recurring income from one-time windfalls or non-qualifying sources.
This process is different from how lenders treat W-2 employees. Your tax return includes business deductions, depreciation, and various income sources that may not represent your actual cash flow or ability to make mortgage payments.
Say you're a freelance consultant who also receives rental income and sold some stock last year. Your lender will analyze each income source separately. Your consulting income goes through the self-employment analysis in [[B3-3.2]], while your rental income gets evaluated under different rules, and your stock sale proceeds likely won't count as qualifying income at all.
Wages, Salary, and Tips on Your 1040
If your Form 1040 shows wages, salary, or tips, this creates questions for your lender. As a self-employed person, this income typically comes from one of two sources.
You might operate as an S-corporation and pay yourself a salary. In this case, the wages represent part of your business income and get included in the overall self-employment analysis.
Alternatively, your spouse might be employed either by your business or by another company. If your spouse works for another employer and you want to use their income for qualifying, your lender must verify that income directly with the employer. They can't rely on what's reported on your joint tax return because your spouse's current earnings might be different from what was reported last year.
Your lender will subtract any spouse's employment income from your cash flow calculation if they're verifying it separately or if you're not using it for qualifying purposes.
Interest and Dividend Income Requirements
Interest and dividend income from your investments can count as qualifying income, but only under specific conditions. You must have received this income for at least two years, and it must be expected to continue.
Your lender will review Schedule B of your tax return to verify the amounts and sources. They'll also check that you're not liquidating these same investments to fund your down payment or closing costs. You can't count income from assets you're selling to buy the house.
Say you have $50,000 in dividend-paying stocks that generated $2,000 in income last year and $1,800 the year before. If you're keeping these investments, your lender can use the income. But if you're selling $20,000 worth of these stocks for your down payment, the lender must reduce the qualifying dividend income proportionally.
Tax-exempt interest from municipal bonds follows the same two-year rule. If you've been receiving this income consistently and plan to continue, it can be added to your cash flow for qualifying purposes.
What Gets Subtracted From Your Income
Several items on your Form 1040 must be removed from your qualifying income because they're not recurring or reliable.
State and local tax refunds get subtracted because this money was already counted in previous years' income calculations. Including it again would be double-counting.
Any alimony, unemployment compensation, or other income sources that don't meet the specific requirements in [[B3-3.1-09]] must be removed from your cash flow.
One-time income like lottery winnings, insurance settlements, or irregular bonuses also gets subtracted. Your lender needs to see income that will continue for at least three years after your mortgage closes.
Retirement and Social Security Income
Income from IRA distributions, pensions, annuities, and Social Security can strengthen your qualifying income picture. These sources often provide stable, long-term income that lenders view favorably.
The nontaxable portion of this income gets special treatment. Your lender can add back the tax-exempt portion to your cash flow since you don't pay income tax on it. This effectively increases your qualifying income.
For example, if you receive $2,000 monthly in Social Security benefits but only $1,500 is taxable, your lender can count the full $2,000 toward qualifying income. The $500 nontaxable portion gets added back to your cash flow.
However, if any retirement income is temporary or will stop within three years, it must be subtracted from your qualifying income calculation.
Required Documentation
Your lender needs complete tax returns including all schedules and forms. For Form 1040 analysis, this typically includes:
- Form 1040 for the most recent two years
- Schedule B (Interest and Dividend Income) if applicable
- Schedule E (Supplemental Income and Loss) for rental or partnership income
- Form 1099s for interest, dividends, and other income sources
- Account statements for investment accounts generating income
- Documentation showing the continuance of retirement or Social Security income
If your spouse's employment income appears on your joint return, your lender will also need current pay stubs, employment verification, and possibly tax transcripts to verify that income separately.
Why These Rules Exist
Fannie Mae requires this detailed analysis because self-employed borrowers' tax returns often don't reflect their true cash flow. Tax returns are designed to minimize taxable income through legal deductions and depreciation, while mortgage qualification focuses on actual cash available for debt payments.
The two-year requirement for investment income ensures stability. Markets fluctuate, and companies can cut or eliminate dividends. A two-year history helps demonstrate that the income source is reliable enough to support mortgage payments.
The prohibition on using income from assets being liquidated prevents borrowers from overstating their financial capacity. If you're selling investments for your down payment, that income won't be available to support future mortgage payments.
Common Complications
Several situations can complicate the Form 1040 analysis. If your investment income declined significantly year-over-year, your lender may not be able to use the full amount or any of it for qualifying purposes.
Mixed business and personal use of assets creates documentation challenges. If you use your home office for business and also claim mortgage interest as a personal deduction, your lender needs to understand how these items affect your cash flow.
Timing differences between tax years and your mortgage application can also create issues. If you sold income-producing assets after filing your most recent tax return, your lender needs current documentation showing your revised income picture.
Joint tax returns with non-applicant spouses require careful separation of income sources. Your lender must identify which income belongs to you versus your spouse and verify accordingly.

Overview
To get an accurate picture of the borrower’s cash flow, the lender will need to make certain adjustments to some of the income (or loss) that the borrower reported on IRS Form 1040 since it may not be recurring income. The lender also may need to further analyze the accompanying tax schedules or supplemental tax forms.
This section describes how the lender should treat various components of the income (or loss) that a self-employed borrower reported on IRS Form 1040 in its cash flow analysis.
Note: Eligibility criteria for accepting income from specific non-business sources is generally the same as that for salaried or commissioned borrowers (see
Wages, Salary, and Tips
If an amount is shown for wages, salary, or tips for a self-employed borrower, it may mean:
the borrower operates as a corporation and pays himself or herself a salary or
the borrower’s spouse is employed and receives a salary (either from the borrower’s business or from another employer).
If the income relates to the borrower’s spouse who is employed by another company and the income will be used in qualifying for the mortgage, the spouse’s income must be verified directly with their employer since it may be more appropriate to use the spouse’s current earnings in underwriting the mortgage. Any income that is based on current earnings or that will not be used for qualifying purposes should be deducted from the borrower’s cash flow.
Interest and Dividend Income
The taxable interest and dividend income that is reported on IRS Form 1040, Schedule B, may be counted as stable income only if it has been received for the past two years. However, the income cannot be counted if the borrower is using the interest-bearing or dividend-producing asset as the source of the down payment or closing costs.
Any taxable interest or dividend income that is not recurring must be deducted from the borrower’s cash flow.
Tax-exempt interest income may be counted as stable income only if it has been received for the past two years and is expected to continue. If so, this income can be added to the borrower’s cash flow.
State and Local Tax Refunds
Taxable state and local tax refunds, credits, or offsets of state and local income taxes should not be used as qualifying income since the income was accounted for in the previous year’s tax returns. Therefore, the borrower’s cash flow must be adjusted accordingly.
Alimony Received
Alimony may be accepted as qualifying income if it meets the requirements described in B3-3.1-09, Other Sources of Income. Any reported alimony received that is determined to be nonrecurring must be deducted from the borrower’s total income reported on IRS Form 1040.
IRA Distributions, Pensions and Annuities, and Social Security Benefits
Income received from IRA distributions, pensions, annuities, and Social Security benefits may be accepted as qualifying income. See B3-3.1-09, Other Sources of Income, for specific requirements.
The nontaxable portion of such recurring income must be added to the borrower’s cash flow. The tax-exempt portion of income from these sources may be increased to reflect the tax savings, as described in B3-3.1-01, General Income Information. If the income from these sources is determined to be nonrecurring, the income must be deducted from the borrower’s cash flow.
Unemployment Compensation
Unemployment compensation may be considered as acceptable qualifying income if it meets the requirements described in B3-3.1-09, Other Sources of Income. Any reported unemployment compensation that is determined to be nonrecurring must be deducted from the borrower’s cash flow.
Other Income (or Loss)
If the borrower reported income from other sources, the lender must verify that the income is an eligible source for qualifying purposes per the requirements described in B3-3.1-09, Other Sources of Income, for the applicable income source. Income that is determined to be nonrecurring or ineligible for qualifying purposes must be deducted from the borrower’s cash flow. If the borrower reported any nonrecurring losses, the borrower’s cash flow should be increased by the amount of the losses.
