To resolve mortgage income verification errors, first ask your lender to identify the disputed field or validation message. An employer-name mismatch, missing pay and an outdated record can require different fixes. Corrected data does not establish qualifying income—the income the lender can count toward eligibility—or guarantee approval. Fannie Mae’s underwriting guidance leaves the approval decision with the lender.

This guide focuses on U.S. borrowers with employment income. The Fannie Mae examples concern conventional loans using Desktop Underwriter, or DU; other programs have their own requirements. Have your loan officer confirm the rules for your loan program and underwriting process.

What automated verification retrieves

An employment and income verification report can contain employer information, employment status, time with the employer, and year-to-date or prior-year earnings. ADP’s Employment Verification Reference Guide, published in 2023, illustrates these details in reports from The Work Number. What is available depends on the report and its underlying data.

The Work Number gathers information from employers and payroll processors, according to the Consumer Financial Protection Bureau. Another verification route uses bank-account transactions: Fannie Mae permits qualifying asset reports containing at least 12 months of data to support income and employment validation, as described in its April 22, 2026 Selling Guide.

These processes have three distinct stages: a source supplies records, a verification service produces a report, and the lender uses the evidence to assess your application. Understanding those roles helps you identify who needs to act when mortgage technology flags an exception.

1. Pinpoint the discrepancy

Ask your loan officer for the report provider’s name, report date and reference number, plus the specific discrepancy or validation message. Request a copy of the relevant information or instructions for obtaining your own report.

Make a short comparison identifying:

• What the disputed field says and what you believe it should say.
• The employer, pay period and income category involved.
• The document supporting your correction.
• Whether the discrepancy appears in the application, payroll record or verification report.

Ask whether the system could not retrieve a report, could not match an employer, or found that the data did not support the income entered. Fannie Mae distinguishes information that does not support the application from information it cannot validate because data is inaccessible or insufficient. Selling Guide B3-2-02 directs lenders to the resulting documentation messages.

Check whether different names identify the same employer

An employer-name mismatch does not necessarily mean the wages are wrong. Under Fannie Mae’s DU validation FAQs, the lender may update the employer name in DU and resubmit after confirming that the different names identify the same employer.

Fannie Mae enhanced employer-name matching for submissions and resubmissions on or after April 24, 2026. If a mismatch persists after resubmission, the findings message identifies the active employer names observed in the verification report, according to its release notes published April 15, 2026.

Use those names to ask payroll about an unfamiliar legal entity or payroll name. If the listed employer is actually wrong, request a correction rather than changing the application merely to produce a match.

Compare missing pay over the same period

Compare the same earnings category over the same period. Check the report’s underlying data date, the latest pay period included, and whether the amount represents gross earnings or the deposit after deductions.

Ask payroll whether the disputed payment appears in its records and whether it was transmitted to the verification provider. If payroll shows the payment but the report omits it, give the provider that specific discrepancy. If the report accurately reflects an earlier period, ask the lender whether it needs a refreshed report instead of an error dispute.

2. Correct the record and keep the lender involved

Your employer and the reporting company may both need to act. Equifax’s employer dispute instructions explain that correcting the employer’s payroll file can remedy data problems and describe how employers can submit disputes to The Work Number.

You can dispute inaccurate or incomplete information in a consumer report with both the reporting company and the company that supplied it. The investigation must be conducted without charge, according to the CFPB’s explanation of consumer-report correction rights.

Send a concise explanation with supporting copies through the recipient’s secure process. Keep the original documents, submission date, case number and written response. Tell the loan officer that a correction is pending and agree on who will obtain the replacement report.

An active dispute affects validation: DU will not use an employment or income record with an active dispute. After resolution, the lender can order another report and resubmit with its updated reference number, under Fannie Mae’s dispute guidance. Ask the lender for an alternative documentation plan while the investigation proceeds.

3. Agree on the documents needed for the loan file

Ask which documents the lender needs and what each must establish. Depending on the income and unresolved issue, the request may include recent paystubs showing year-to-date earnings, the required W-2 history, or an employer-completed verification of employment, such as Form 1005.

Fannie Mae’s documentation standards, dated March 4, 2026, require lenders to supplement third-party verifications when information is missing. They also require sufficient information to calculate income; a recent paystub alone may not answer every question.

For a naming issue, ask what evidence will establish the relationship between the names. For missing compensation, identify the pay date, category and amount. Provide original employer-issued documents and keep your explanation separate; do not edit the underlying paystub or report.

Freddie Mac has a separate process through Loan Product Advisor and its asset and income modeler, AIM. Its third-party verification requirements, in the May 6, 2026 Guide, require missing information to be supplemented and make the lender responsible for data accuracy and integrity. Its automated income-assessment requirements in Guide section 5303.4 also call for resolving contradictory information. Follow the instructions for the system handling your loan.

4. Confirm what income the lender can use

Once the evidence is corrected, ask for the monthly qualifying income and how the lender calculated it. A payment can be accurately reported yet require different treatment from regular salary.

In a hypothetical example, a corrected record adds a $12,000 annual bonus. Dividing it by 12 produces $1,000 a month, but that arithmetic alone does not establish how much the lender can use. Fannie Mae’s standard bonus-income requirements also address receipt history and earnings trends. The lender must apply the applicable assessment method.

Validation can cover only particular income. Fannie Mae assesses validation by employer and income type for new DU casefiles created on or after June 27, 2026, under its April 1, 2026 announcement. Ask which earnings received validation and which still require documentation.

Even when DU validation succeeds, the lender must still assess the application, investigate contradictory information and satisfy the conditions in the underwriting findings. Fannie Mae’s lender requirements preserve those duties; validation does not guarantee mortgage approval.

5. Check timing, costs and remaining conditions

Do not assume a dispute will finish before closing. Consumer-report reinvestigations generally have a 30-day deadline, with extensions or a 45-day period in specified circumstances. The CFPB’s examination procedures describe those deadlines. They are not promises that a refreshed report and underwriting review will be complete within that time.

The Work Number provides a free consumer report on request, according to the CFPB. Ask separately whether a lender-ordered replacement report or a closing delay would create charges for your transaction.

Check the employment-verification deadline as well: DU messages can specify a close-by date that matters to validation, as explained in Fannie Mae’s April 22, 2026 Selling Guide.

Before treating the exception as resolved, ask for written confirmation that the lender has accepted the evidence, updated the application where needed, and identified the income it will use and any remaining conditions. Keep that confirmation with your home-purchase documents so you have a record of what still needs to happen before closing.
