You can gross up disability income for a mortgage as long as the benefit is exempt from federal income tax. Fannie Mae, Freddie Mac, VA, and USDA loans generally allow a 25% increase to your nontaxable disability income when calculating qualifying income, while FHA caps the adjustment at the greater of 15% or your actual prior-year tax rate. The result is a higher qualifying income on paper without changing the actual benefit you receive.
How the Gross-Up Works
Mortgage underwriting compares your monthly debts to your gross monthly income. For a wage earner, gross means the full paycheck before taxes come out. Disability benefits that are tax-free arrive as net dollars with no equivalent pre-tax figure, so using the raw amount understates your buying power next to a taxable earner who nets the same.
The gross-up fixes that. The lender multiplies your nontaxable benefit by a set percentage so it approximates what a taxable earner would need to gross to bring home the same amount. Your debt-to-income ratio improves, and the loan you qualify for tracks your actual purchasing power. You do not get extra money; the adjustment lives entirely on the underwriting worksheet.
Gross-Up Percentages by Loan Program
The percentage is not standardized. The differences between programs can shift how much house you qualify for by tens of thousands of dollars.
Fannie Mae and Freddie Mac (Conventional)
Both agencies allow a 25% gross-up as the standard. A $2,000 monthly benefit counts as $2,500 for qualifying. If your combined federal and state tax rate would actually exceed 25%, the lender may use that higher figure instead.1Fannie Mae. General Income Information So 25% is a floor for conventional loans, not a ceiling.
FHA
FHA loans use a different rule. The gross-up cannot exceed the greater of 15% or your actual tax rate from the prior year. If you were not required to file a return, the lender is capped at 15%.2HUD. FHA Single Family Housing Policy Handbook A borrower in a low tax bracket often sees a smaller boost on an FHA loan than on a conventional one.
VA
VA loans permit a 25% gross-up when calculating the debt-to-income ratio. VA underwriting also runs a separate residual income test measuring actual cash left after debts and housing costs, and that test uses your real benefit amount, not the grossed-up figure.3Veterans Benefits Administration. Credit Underwriting Passing the ratio thanks to the gross-up does not guarantee approval if actual take-home falls short of the residual income threshold.

Which Disability Income Qualifies
The rule underneath all of this is the same: only income exempt from federal income tax can be grossed up. If part of the benefit is taxable, only the tax-free portion gets the adjustment.
VA Disability Compensation
VA disability compensation is entirely tax-free by federal statute.5GovInfo. Title 38 United States Code 5301 – Nonassignability and Exempt Status of Benefits The same applies to Dependency and Indemnity Compensation and Special Monthly Compensation.6Veterans Benefits Administration. Compensation The IRS confirms these benefits are not included in gross income.7Internal Revenue Service. Veterans’ Tax Information and Services This is the cleanest category for a full gross-up.
Social Security Disability Insurance
SSDI qualifies, but only the nontaxable portion. Depending on your total income, some of your SSDI may be taxable, which limits how much can be grossed up. The thresholds are covered in the next section.
Private Long-Term Disability
Benefits from a private policy are nontaxable if you paid the premiums with after-tax dollars. If your employer paid or you paid through pre-tax payroll deductions, the benefits are taxable and cannot be grossed up. When premiums are split, only the employer-paid portion of the benefit is taxable.8Internal Revenue Service. Life Insurance and Disability Insurance Proceeds
Workers’ Compensation
Workers’ comp benefits for job-related injury or illness are fully exempt from federal income tax and qualify for grossing up.9Office of the Law Revision Counsel. 26 U.S. Code 104 – Compensation for Injuries or Sickness If your workers’ comp reduces your Social Security benefits, the offset amount is treated as Social Security income and may be taxable.10Internal Revenue Service. Publication 525 (2025), Taxable and Nontaxable Income Workers’ comp with a limited duration also faces the continuance scrutiny discussed below.
How SSDI Taxability Affects the Gross-Up
SSDI is a special case because its tax-exempt status depends on your other income. The IRS uses “provisional income” for this calculation: your adjusted gross income plus tax-exempt interest plus half of your Social Security benefits.
For single filers, no SSDI is taxed if provisional income stays below $25,000. Between $25,000 and $34,000, up to 50% of benefits become taxable. Above $34,000, up to 85% become taxable.11Internal Revenue Service. Publication 915 (2025), Social Security and Equivalent Railroad Retirement Benefits
For married couples filing jointly, the no-tax threshold is $32,000. Between $32,000 and $44,000, up to 50% is taxable. Above $44,000, up to 85% is taxable.
If you file married filing separately and lived with your spouse at any point during the year, up to 85% of your benefits are taxable regardless of income level. Borrowers whose SSDI falls entirely below the thresholds get the simplest full gross-up. Everyone else needs recent tax returns to show which slice of the benefit is actually exempt, because only that slice qualifies.
The Three-Year Continuance Requirement
A gross-up only applies to income the lender expects to last. Fannie Mae and Freddie Mac require documentation that a benefit with a defined expiration or a depleting source will continue at least three years from the note date.12Fannie Mae. General Income Information – Section: Continuance of Income FHA applies the same three-year standard to government assistance and disability payments.13HUD. HUD 4155.1 Volume 4 Section E – Non-Employment Related Borrower Income
When an award letter has no stated expiration, FHA treats the income as reasonably likely to continue. For SSDI, the Social Security Administration assigns a medical diary code that sets the next review date. A default code of “3” triggers a review in 36 months. If your review is scheduled within three years of your closing, some lenders may ask for a physician’s letter confirming the disability is expected to persist.14Social Security Administration. An Overview of Processing Continuing Disability Review (CDR) Mailer Forms SSA-455 and SSA-455-OCR-SM Disabilities classified as permanent often carry longer review intervals or none, which simplifies underwriting.
Documentation You’ll Need
Every lender needs two things: proof of the benefit amount and proof that the income is nontaxable.
- For SSDI, request a benefit verification letter through your my Social Security account, and expect to provide your most recent tax return so the lender can see how much of the benefit was actually taxed.15Social Security Administration. How Can I Get a Benefit Verification Letter?
- For VA disability compensation, download a VA Benefit Summary Letter through eBenefits or VA.gov showing the compensation amount and tax-exempt status.
- For private long-term disability, provide the policy or a statement from the administrator confirming the amount, the duration, and that premiums were paid with after-tax dollars.
- For workers’ compensation, provide the award letter or settlement document plus confirmation from the paying agency that benefits are ongoing.
Income Types That Generally Don’t Qualify
Short-term disability almost never works. These policies typically pay for a few months to a year, well short of the three-year continuance requirement. Even fully nontaxable short-term benefits give the lender no basis to project income across a 15- or 30-year mortgage.
Supplemental Security Income is technically nontaxable but hard to use. SSI is needs-based with resource limits of $2,000 for an individual and $3,000 for a couple. Large deposits, down payment gift funds, or closing timing can push you over the limit and interrupt benefits, which in turn can pause or kill the loan. Many lenders treat SSI conservatively, and some do not gross it up at all. If SSI is your primary income, coordinate the timing of financial moves with both your lender and SSA before closing.
What the Gross-Up Looks Like in Dollars
Take a borrower receiving $2,400 per month in VA disability compensation, applying for a conventional loan. VA disability is fully tax-exempt, so the lender applies the 25% gross-up: $2,400 × 1.25 = $3,000 in qualifying income. With $800 per month in car and student loan payments, the debt-to-income ratio comes to about 26.7%. Without the gross-up, the same debts against $2,400 produce 33.3%. That 6.6-point swing can decide whether the loan amount you want gets approved.
Now shift to an FHA loan where the borrower did not file a return last year. FHA caps the gross-up at 15%, so $2,400 becomes $2,760 rather than $3,000. The ratio lands at 29%, better than the raw number but noticeably weaker than the conventional calculation. Borrowers with nontaxable disability income who can choose between programs should run both scenarios, because the gross-up difference alone can change how much home is within reach.
