USDA Loan Single Income: Whose Income and Debts Count

The question shows up in my inbox a few different ways. Sometimes it's a single buyer who wants to know if one paycheck is enough. More often it's one spouse in a Texas or Arizona couple asking whether they can leave the other spouse off the loan, usually because of a credit score or a pile of debt, and have the lender just ignore that person.

The first part is easy. Yes, you can get a USDA guaranteed loan on one income. The second part is where people get surprised, because "only one of us is on the loan" doesn't mean the underwriter only looks at one of you.

Can I get a USDA loan by myself on one income?

Yes. Nothing in USDA's rules requires two borrowers. Plenty of single buyers and one-earner households close USDA loans.

What trips people up is that USDA runs two separate income tests, and they use different groups of people. If you understand which test pulls in whom, almost every "does my spouse count?" question answers itself.

Household income vs. repayment income

Household income decides whether you're under the program's income limit. HB-1-3555, Chapter 9, and the regulation behind it (7 CFR 3555.152) say annual income includes eligible income from household members, including non-borrowers, meaning the adults who live or will live in the home. The income matrix USDA gives lenders, Attachment 9-A, puts it bluntly: "not just parties to the loan note."

That doesn't mean every dollar from every adult counts in full. If an adult full-time student in the home isn't an applicant or the spouse of one, Attachment 9-A counts only the first $480 of their earnings. That cap tracks an indexed HUD figure, so let the USDA calculator apply the current amount. A minor's own wages don't count unless the minor is an applicant or married to a household member, but income received on a child's behalf, like benefits paid to the parent, does. And live-in aides aren't household members at all under 7 CFR 3555.10, so their income stays out. The same goes for kids or adults placed in your home for care, along with what you're paid to look after them.

Repayment income decides how much house you can carry. Chapter 9 defines it as the stable and dependable income of the applicants who will be parties to the note. Nobody else's paycheck goes into your debt ratios. USDA also doesn't allow co-signers or non-occupant co-borrowers on guaranteed loans, so you can't bring in a parent from across town to boost your numbers.

So an adult who lives with you but isn't on the loan can hurt you on the income limit and do nothing to help your ratios. Most of the spouse questions below come back to that. If you want the full method for the eligibility side, I walk through it in how to calculate USDA household income.

Buying truly solo

A one-person household is the simplest USDA file there is, because there's no other adult whose income gets pulled into the limit. That doesn't mean both tests land on the same number, though. USDA Chapter 9 has the lender calculate three figures even for one person. Annual income is your gross income from all eligible sources, projected over the next 12 months. Adjusted annual income is that figure minus any deductions you qualify for (an applicant 62 or older gets the elderly family deduction, for example), and that's what gets compared to the limit. Repayment income works differently. Only income that's stable, has the required history and can be expected to continue at least three years counts, and tax-exempt income can be grossed up for repayment but not for the limit. So the same paycheck can show up as different numbers on the two sides of the file.

The income limit is set by county and household size and is usually updated each July, so check your county on USDA's eligibility site rather than trusting a number from last year. If the household's countable net family assets total $50,000 or more (the lender applies the exclusions, including retirement accounts), Chapter 9 has the lender add the actual or imputed earnings on those assets to annual income. For a single buyer with a healthy savings account, that can nudge you toward the limit.

The ratios are where solo buyers feel the squeeze. USDA sets a housing ratio and a total debt ratio in Chapter 11, and GUS (USDA's automated underwriting system) can approve files above them when the rest of the file is strong. On one paycheck, every car loan and card minimum comes straight out of the room you have for a house payment. If I'm being honest with a solo buyer, paying off one monthly debt before applying often does more than any other single move.

For a single parent, child support or alimony you receive can count as repayment income if it's documented and expected to continue. The same three-year continuance test applies to every repayment income source. If that support ends in two years because a child ages out, it gets harder to use. Attachment 9-A lays out the history and paperwork each income type needs.

USDA loan, one income, married: does my spouse's income count?

For the income limit, usually yes. Chapter 9 says a non-borrowing spouse's income goes into annual income if you live together. There are two exceptions. One is if the spouse has been living apart from you for at least 3 months for reasons other than military or work assignment. The other is if divorce or legal separation proceedings have started. Either one has to be documented. For living apart, that's usually a separate lease or utility bills at another address. For proceedings, it's the filed petition. A spouse away on deployment or a temporary work assignment still counts.

A spouse who isn't working right now isn't automatically zero, either. If an adult household member is unemployed but looking for work, Chapter 9 has the lender include their previous earnings. That stops only if there's documentation that they aren't seeking reemployment, such as a signed statement from them saying so. A stay-at-home spouse who signs that statement usually counts as no income. A spouse between jobs and actively applying may not.

One-earner couples with young kids should also know this. USDA lets you deduct childcare costs for kids 12 and under from household income, which helps you get under the limit. Under 7 CFR 3555.152(c)(2), the deduction covers care that lets a household member work, actively look for work or go to school, and it isn't allowed if another adult in the household is available to care for the child. A spouse who's home and able to watch the kids usually means no deduction. Being home isn't the same as being available, though. If the childcare lets your spouse actively job hunt, or a disability keeps them from providing care, ask your lender how they'll document that. The per-child dependent deduction applies either way. Its amount is tied to HUD's indexed figure and has been updated recently, so let the USDA income calculator apply the current number.

For repayment, your spouse's income only counts if they're on the note. That's the price of leaving them off.

USDA community property state: the non-purchasing spouse's debt

Texas and Arizona are both community property states, and this is where the "just leave them off" plan usually falls apart.

HB-1-3555, Chapter 11, paragraph 11.2.B.14 says applicants who currently live in, or are buying in, a community property state must include the debts of the non-purchasing spouse (NPS) in the debt ratio unless state law specifically excludes them. The word "or" matters. If you live in Texas now and you're buying in Texas, it applies. If you're relocating from another state into Arizona, it still applies.

Here's how it works on the file. GUS only pulls credit for applicants, so Chapter 10, Attachment 10-A has the lender pull a separate credit report on your spouse outside GUS. The lender enters each of their debts in GUS manually, labeled as NPS debt. Since Procedure Notice 649 in August 2025, that report goes in the lender's permanent file instead of being uploaded to USDA. But it's still pulled. Your lender may also ask your spouse to sign a credit authorization under its own policy.

The exception is narrow. A lender can leave out a specific NPS debt only if a state statute excludes it from community liability, and the lender has to keep a copy of that statute in the file. In practice, I treat the spouse's car loan, cards and student loans as going into your ratio unless we can point to the statute that says otherwise.

When leaving a spouse off helps, and when it backfires

Leaving a spouse off the note does change one real thing. Because GUS pulls credit only on applicants, the score being evaluated is yours. If your spouse is carrying a recent collection or a low score and you're not, that separation can matter. USDA's Chapter 10 guidance says the NPS's credit history alone isn't a reason to deny your application. Their debts still count, as above, and some lenders add their own policies, so ask how yours treats a rough NPS report.

What it doesn't do in Texas or Arizona is hide their debt. You get their monthly obligations in your ratio and none of their income to offset them. On one paycheck, that stings. We see this a lot when the NPS report comes back. There's a car loan or store card nobody mentioned, and a ratio that looked fine at pre-approval suddenly doesn't.

The math usually works out like this:

• Spouse has a low score and little debt: leaving them off tends to help, since you keep your score and their small debts barely move the ratio.
• Spouse has a decent score, real income, and debt: putting them on usually helps, since their income now offsets debts that would have counted anyway.
• Spouse has a low score and heavy debt: this is the hard case. Their debts count either way, so the question becomes whether you can carry them on your income alone. We run it both ways before you decide.

Ways one earner can strengthen the file

The levers are mostly on the debt side, because the income side only grows with people on the note. Pay down or pay off installment debts, yours or your spouse's, since in Texas and Arizona both land in the ratio. Keep cash in the bank after closing, since reserves are one of the things that help GUS and underwriters get comfortable above the standard ratios. A part-time or second job can count as repayment income too, if it has the history and continuance Attachment 9-A requires. One that started three months ago generally won't count yet.

If you have tax-exempt income, such as certain disability benefits, Chapter 9 allows it to be grossed up 25 percent for repayment income, not for the household income limit.

Worked example: Pinal County vs. Ellis County

These are illustrative people, not clients. Say a married couple has one spouse earning $68,000 as a lineman. The other spouse works part-time for $22,000 and carries a car loan plus two credit cards near their limits. The lineman wants to apply alone.

For the income limit, the household number is $90,000, both incomes, no matter who signs. For repayment, it's $68,000. The spouse's car and card payments still go into the debt ratio because they're buying in a community property state.

Now put that couple in Casa Grande in Pinal County, then in Waxahachie in Ellis County. The rules are the same in both places. The income limit isn't, because USDA sets it by county and household size, so how much room this household has under the cap depends on where they buy. The county matters most for households that sit nearer their limit, say one with a working adult child at home who isn't a full-time student, or a big expected raise. Pull both counties on the eligibility site before you fall for a house.

In both places, adding the part-time spouse to the note would put that $22,000 into repayment income against debts that are already counted. Unless their credit is a real problem, that's often the stronger file.

Decision checklist: who should be on the application

Before you decide, answer these honestly:

1. Does the eligible income of every adult who'll live in the home, borrower or not, fit under your county's household income limit? (Factor in the special rules for adult full-time students and income received for your kids.)
2. Is your spouse working, between jobs and looking, or not seeking work? Can they document that?
3. What does your spouse's credit report show, both score and monthly debts?
4. Does your income alone carry the house payment plus both spouses' debts?
5. If they're added, does their income meet the minimum history Attachment 9-A sets for that income type, and can it be confirmed to continue at least three years?

If the answers point in different directions, that's normal. It's why we run the file both ways.

Start with the qualifier quiz. Put in your household size, everyone's income and the county you're shopping, and I'll tell you whether this works better with one name on the loan or two.
