Mortgage lenders count almost any income you can prove is real, recurring, and likely to continue for at least three years. That includes W-2 wages, self-employment profit, bonuses and commissions with a track record, rental income, Social Security and pensions, alimony and child support, investment earnings, and in some cases a drawdown from retirement assets. The question of what income mortgage lenders count comes down to two tests applied to every dollar: can you document it, and will it keep coming in?
The federal Ability-to-Repay rule requires lenders to verify your current income, employment, debts, and credit history before approving a mortgage.1Federal Register. Ability-to-Repay and Qualified Mortgage Standards Under the Truth in Lending Act (Regulation Z) How a lender treats each income stream is where approvals are won or lost.
Income Sources Lenders Accept
Base wages from a salaried or hourly job are the easiest to document and the most predictable to underwrite. Beyond that, the following sources can be used to qualify:
- Commissions, bonuses, overtime, and tips, where you have at least a 12-month history showing a stable or increasing trend.2Fannie Mae Selling Guide. Bonus, Commission, Overtime, and Tip Income
- Net rental income from investment properties, reduced from gross rent to account for vacancies and maintenance.
- Interest, dividends, and other recurring investment earnings, if documented and expected to continue.
- Court-ordered alimony and child support, with a receipt history and expectation of continuing payments.3Fannie Mae. Fannie Mae Selling Guide – General Income Information
- Social Security, disability, and pension payments, supported by an award letter or benefits statement.
- Self-employment income, calculated from your tax returns.
Not every dollar that hits your bank account qualifies. One-time windfalls, lawsuit proceeds, virtual currency, non-vested restricted stock, and stock options generally cannot be used.4Fannie Mae. Employment Related Assets as Qualifying Income
The Three-Year Continuity Rule
If an income source has a defined expiration date or depends on drawing down a limited asset, the lender must document that it will continue for at least three years from the loan’s note date.3Fannie Mae. Fannie Mae Selling Guide – General Income Information This is the rule that catches most borrowers off guard. A two-year consulting contract paying $5,000 a month isn’t usable even though the money is substantial today. Child support that ends in eighteen months when a child turns 18 won’t count either. The income has to outlast a three-year horizon.
How Variable Pay Gets Averaged
Bonuses, overtime, commissions, and tips don’t follow a predictable schedule, so lenders convert them into a monthly average. The lender looks at your year-to-date earnings and prior years, requires at least 12 months of history, and averages the figures if the trend is stable or rising.2Fannie Mae Selling Guide. Bonus, Commission, Overtime, and Tip Income
Declining variable income is a different story. The lender can’t blend strong early years with a weaker current year and treat the average as reliable. The current level has to be shown to have stabilized after the decline. If it hasn’t, that income stream is excluded from qualifying entirely. This is the single most common place where borrowers overestimate what they’ll be approved for.
Self-Employment Income
If you own 25% or more of a business, the lender treats you as self-employed, even if you also draw a W-2 salary from that business.5Fannie Mae. Standards for Employment-Related Income You qualify on net income after business expenses, not gross revenue. A business pulling in $400,000 a year that shows $60,000 in net profit on your tax return gives the underwriter $5,000 a month to work with.
The lender must prepare a written cash flow analysis of your personal and business tax returns, using Fannie Mae’s Form 1084 or an equivalent method, to arrive at a stable ongoing income figure.6Fannie Mae. Underwriting Factors and Documentation for a Self-Employed Borrower If your application dates more than 120 days after your business’s tax year ends, expect a request for a year-to-date profit and loss statement.7Fannie Mae. Analyzing Profit and Loss Statements Year-over-year decline triggers the same stabilization test used for variable pay.
Non-Taxable Income Can Be Grossed Up
Income that isn’t subject to federal income tax can be “grossed up” so it competes fairly with taxable earnings. The typical adjustment is 25%, meaning $2,000 a month in non-taxable Social Security qualifies as if it were $2,500. The gross-up percentage cannot exceed the tax rate that would actually apply to the borrower; where no return is required, 25% is the default.8U.S. Department of Housing and Urban Development (HUD). HUD 4155.1 Chapter 4, Section E – Non-Employment Related Borrower Income
Eligible sources include certain Social Security benefits, some government retirement income, Railroad Retirement, certain disability and public assistance payments, child support, and military allowances. Tell your lender about any non-taxable stream before they run the numbers. The adjustment can meaningfully change what you qualify for.
Using Retirement Assets as Income
Borrowers with substantial retirement savings but limited paycheck income, including early retirees, can sometimes qualify through an asset depletion method. The lender takes your net documented assets and divides by the number of months in the loan term to produce a monthly income figure.
Only employment-related assets count: 401(k)s, IRAs, SEPs, and Keogh plans. The lender subtracts any early withdrawal penalty and the funds needed for your down payment, closing costs, and reserves before dividing. Ordinary checking and savings don’t qualify unless the balance came from an eligible source such as a severance package or lump-sum retirement distribution.4Fannie Mae. Employment Related Assets as Qualifying Income
Qualifying on a Job Offer
If you have a signed offer letter but haven’t started work, Fannie Mae permits qualifying on the offer when the start date falls no earlier than 30 days before the note date and no later than 90 days after it. The offer must be fully executed and non-contingent. Where no paystub is available before loan delivery, the lender must document either six months of mortgage payment reserves for the property or enough financial resources to cover all monthly obligations from the note date through the start date plus one additional month.9Fannie Mae. Employment Offers or Contracts
One boundary: the offer can’t come from a family member or from anyone with an interest in the transaction, such as the seller or the listing agent.9Fannie Mae. Employment Offers or Contracts
What You Need to Document Each Source
Gather these before you apply. Missing items stall the file.
Tax Returns
Federal returns (Form 1040) for the two most recent years. Self-employed borrowers add business returns and relevant Schedule C, K-1, or 1120-S forms.
Paystubs and W-2s
Paystubs covering the last 30 days, showing name, employer, pay period, year-to-date earnings, and withholdings. Hourly workers need hours worked on the stub. W-2s and 1099-NEC forms for the past two years; employers and clients must issue them by January 31.10Internal Revenue Service. Form W-2 and Other Wage Statements Deadline Coming Up for Employers
Benefits and Support Documentation
Award letters for Social Security, disability, or pension payments showing amount and frequency. Court orders and payment history for alimony or child support.
Bank Statements
Two months of statements for a purchase, generally one for a refinance. If your most recent statement is more than 45 days old when you apply, the lender will want a supplemental bank-generated document showing the balance and date.11Fannie Mae. Verification of Deposits and Assets
From Monthly Income to Loan Approval
Every qualifying source gets converted to a gross monthly amount, meaning earnings before taxes. Salary divides by 12. Hourly pay runs through an average of weekly hours at the pay rate, annualized, then divided by 12. Variable pay uses the averaging method above.
The lender then measures your monthly debts against that income to produce a debt-to-income ratio. Fannie Mae caps total DTI at 36% for manually underwritten loans, with room up to 45% if you meet additional credit score and reserve requirements. Loans run through Desktop Underwriter can qualify at a DTI as high as 50%.12Fannie Mae. Selling Guide – B3-6-02, Debt-to-Income Ratios The old 43% hard cap from the original qualified mortgage rule was replaced by the CFPB with a price-based threshold, so the ceiling now depends on program and underwriting path rather than a single universal number.13Consumer Financial Protection Bureau. General QM Loan Definition
How Lenders Verify What You Submit
The lender independently checks every figure before signing off.
Tax Transcripts
The lender files Form 4506-C through the IRS Income Verification Express Service to pull official transcripts and compare them line by line against the returns you provided.14Internal Revenue Service. Income Verification Express Service Amended returns still processing and transcription errors are frequent causes of mismatches.
Verbal Verification of Employment
The lender contacts your employer within 10 business days before the note date to confirm you’re still working and still being paid at the stated rate. For self-employed borrowers, the window is 120 calendar days before the note date.15Fannie Mae Selling Guide. B3-3.1-04 – Verbal Verification of Employment Changing jobs or losing one between application and closing is a fast way to collapse a conditional approval.
Large Deposit Review
Any single deposit exceeding 50% of your total monthly qualifying income gets flagged. If those funds are needed for down payment, closing, or reserves, you must document the source: an explanation, proof of an asset sale, or evidence of a gift.16Fannie Mae. Depository Accounts Deposits clearly identified on the statement itself, like direct deposit from your employer or an IRS refund, don’t need additional explanation. The concern is undisclosed borrowing that would change your DTI.
Why Overstating Income Backfires
Every application certifies the information is accurate. Inflating income, inventing an employer, or doctoring returns is a federal crime under 18 U.S.C. ยง 1014, carrying up to 30 years in prison and up to a $1,000,000 fine.17Office of the Law Revision Counsel. 18 USC 1014 – Loan and Credit Applications Generally The 4506-C transcript request exists precisely to catch mismatches between what you submitted and what the IRS has on file.18Internal Revenue Service. Form 4506-C – IVES Request for Transcript of Tax Return Even where an inflated file closes, post-closing audits can surface fraud later, triggering loan acceleration and civil or criminal exposure. The verification process protects you, too: qualifying for a payment you can’t actually sustain rarely ends well.
