Why this number matters so much
The I-864 income test has only two inputs: your income, and your household size. You cannot change your income today. You can absolutely get your household size wrong today — and because the guidelines step up with each person, a single miscount moves the bar by a meaningful amount.
| Household size | Income required (125%, 48 states) | Difference |
|---|---|---|
| 2 | $27,050 | — |
| 3 | $34,150 | +$7,100 |
| 4 | $41,250 | +$7,100 |
| 5 | $48,350 | +$7,100 |
| 6 | $55,450 | +$7,100 |
Figures effective March 1, 2026. Alaska and Hawaii use higher tables — see the full I-864P 2026 chart.
Read that table the other way round and the point lands: if you have counted one person you did not need to count, you have handed yourself a shortfall of $7,100 that does not exist. Before you look at assets, before you ask anyone to be a joint sponsor, recount.
Who you must count
- Yourself. The sponsor is always counted, in every case.
- Your spouse — even if they live elsewhere, even if they have their own income, even if you file taxes separately. Legal marriage is what matters.
- Your unmarried children under 21, whether or not they live with you, unless they are legally emancipated.
- Anyone you claimed as a dependent on your most recent federal tax return, wherever they live — including a parent or sibling you support.
- Every immigrant you are sponsoring on this affidavit, including derivative family members immigrating with the principal applicant.
- Anyone you sponsored on a previous I-864 whose obligation has not yet ended.
Who you do not count
- Roommates and housemates, however long they have lived with you.
- Adult children over 21 who are not your tax dependents.
- Parents or siblings living with you who are not your dependents. They are outside your count — but they may be able to add income by signing Form I-864A, which is often the cleanest fix of all.
- An ex-spouse, once the divorce is final.
- A relative immigrating more than six months from now. They belong on their own affidavit later, not on this one.
- An unmarried partner who is not a tax dependent.
The double-counting trap
This is the single most frequent error, and it is worth its own section.
If you are sponsoring your husband or wife, that person appears in two conceptual places — they are your spouse, and they are the immigrant you are sponsoring. They are one person and they are counted once. A sponsor with no children who is sponsoring their spouse has a household of 2: themselves and their spouse. Not 3.
The same logic applies to a child you are sponsoring: they are counted as the sponsored immigrant, not additionally as your child. Count people, not categories.
Sanity check: write down the actual names of everyone in your household count. If a name appears twice, you have found the error. If the list is shorter than the number on your form, you have found it the other way.
The mirror mistake: undercounting
Overcounting costs you a threshold you did not need to clear. Undercounting is worse, because it produces an affidavit that looks sufficient and then fails on review.
Two things get missed most often. Derivative children immigrating alongside the principal applicant are each a person in your count — sponsoring a spouse and their two children is a household of 4, not 2. And prior I-864 obligations that are still live: if you sponsored a relative six years ago and they have neither naturalized nor accumulated 40 qualifying quarters, they still count against you. Sponsors forget these routinely, because nothing reminds them.
Worked examples
Single sponsor, sponsoring a spouse. You, plus your spouse who is the immigrant. Household of 2 — $27,050.
Married sponsor with one child, sponsoring a parent. You, your spouse, your child, plus the parent you are sponsoring. Household of 4 — $41,250. Note how quickly your own family moves the bar.
Sponsoring a spouse and their two children. You, plus three immigrants. Household of 4 — $41,250.
Single sponsor, sponsoring both parents. You, plus two parents. Household of 3 — $34,150. You file a separate I-864 for each parent, but the household size is the same on both, because both parents are in it either way.
Sponsoring a spouse, with a live prior obligation. You, your new spouse, plus the relative you sponsored in 2019 who has not yet naturalized. Household of 3 — $34,150.
Rather than work these by hand, put your own numbers into the income calculator — it counts each category separately so it is harder to double-count, and it applies the right regional table for you.
When the count is genuinely ambiguous
Most cases are clear. A few are not: a child who turns 21 during processing, a marriage that is separating but not yet dissolved, a dependent you claimed in one year and not the next. These affect the number materially and there is no substitute for advice on your specific facts — this is the point at which a consultation with an immigration attorney is worth the money, because the alternative is guessing on a legally binding form.
What to do once you have the number
Check it against the guidelines with the calculator. If you clear the threshold, move on to assembling your documents. If you fall short, work through the routes in order: recheck this count once more, then household member income via Form I-864A, then assets, then a joint sponsor.
Frequently asked questions
Do I count my spouse if I am sponsoring my spouse?
Once, not twice. The person you are sponsoring appears in your household as the sponsored immigrant. They are the same human being as the spouse on the spouse line, so they are counted a single time. Counting them twice is the most common household-size error and it inflates your requirement by one person.
Do I count a child who lives with their other parent?
Yes, if the child is your unmarried child under 21, or if you claim them as a dependent on your federal tax return. Where the child physically lives does not change the count.
Do I count my parents or siblings living in my home?
Only if you claim them as dependents on your tax return. A relative who lives with you but files their own taxes is not part of your household count — though they may be able to add their income to yours by signing Form I-864A.
Do I count a relative who will immigrate next year?
Not on this affidavit. Someone who will immigrate more than six months from now is counted later, on their own Form I-864, not on this one. Including them now raises your requirement for no reason.
Do I count someone I sponsored years ago?
Yes, if that obligation is still in effect. A prior I-864 obligation ends only when the immigrant naturalizes, is credited with 40 qualifying quarters of work, abandons lawful permanent residence in the United States, dies, or obtains a new grant of adjustment of status in removal proceedings based on a new affidavit of support. Divorce does not end it. Sponsors routinely forget these and undercount.
Does my household size change if I use a joint sponsor?
Your own household size stays the same on your own I-864. The joint sponsor separately counts their own household plus the immigrant, on their form. The two counts are independent.
