How Nontaxable Income Like VA Disability Is Counted in Underwriting

Nontaxable income is income you receive that federal law does not tax. VA disability compensation is the most common example in mortgage files, but the category also includes certain Social Security benefits, some disability payments, some child support, certain public assistance, and portions of some retirement or pension income.

Underwriting does not care whether income is taxed. It cares whether the income is stable, likely to continue, and documentable. A nontaxable source that meets those three tests is treated as real qualifying income, the same as wages.

Where it gets confusing is comparison. A tax return shows taxable income only, so a borrower with substantial nontaxable income can look thinner on paper than they actually are. The grossing-up adjustment exists to correct exactly that distortion.

Grossing up means an underwriter increases the dollar figure of your nontaxable income before using it in the qualifying math, so it can be compared fairly against taxable income. The adjustment reflects what you would have to earn in taxable wages to end up with the same money in hand.

The percentage used is set by the loan program and the guidelines the lender follows, and it varies. Some programs allow a flat adjustment, others tie it to your actual tax bracket as shown on your returns. It is not a number you get to choose, and it is not applied automatically in every file, so it is worth asking early whether your file is being run with the adjustment in place.

One point that trips people up: grossing up changes the qualifying figure only. It does not change your deposits, your bank balance, or anything the IRS sees. It is a calculation convention inside underwriting, nothing more.

Debt-to-income, usually called DTI, is your monthly debt obligations divided by your qualifying monthly income. Because the grossed-up figure is larger than the raw payment amount, the denominator of that fraction grows and the resulting ratio falls, even though nothing about your actual budget changed.

For a borrower with meaningful nontaxable income, that shift can be the difference between a file that looks tight and a file that clearly has room. It can affect which products are available, how much cash you can take out of your equity, and how much reserve cushion the file shows after closing.

This matters most when you are not scraping the edge of approval but deciding how much borrowing capacity to actually use. Seeing the accurate ratio, rather than the understated one, tends to make that decision clearer.

Underwriters need two things proven: that the income is nontaxable, and that it is expected to continue. For VA disability, that generally means the VA award or benefit letter showing the current monthly amount, paired with evidence of receipt such as bank statements or a benefits statement.

Continuance is the piece borrowers often overlook. If an award has a defined end date, the underwriter looks at how long the income is scheduled to last from the date of the loan. Awards with no stated end date are typically easier to treat as ongoing. For other nontaxable sources, an award letter and proof of deposits play the same role.

Gather the award letter before anything else. Files slow down far more often over a missing benefit letter than over anything complicated, and the letter is also what supports the grossing-up adjustment in the first place.

Ask whether your nontaxable income is being grossed up in the file, and at what percentage. Ask which DTI figure is being quoted to you, the one with the adjustment or without it, because the two can look quite different.

Also ask how the continuance test is being applied to your specific award. If the income has a defined end date, the treatment can change, and it is better to know that before you are structuring a cash-out amount around it.
