How to add dependents to your VA disability benefits

At a rating of 30 percent or higher, the law pays extra compensation for dependents, and it can go unclaimed when a veteran does not know the threshold exists.

Last reviewed October 2026 · Not legal advice, VA.gov always controls

If your combined VA disability rating is at least 30 percent, you can get additional compensation for a qualifying spouse, child, or dependent parent (38 CFR § 3.4(b)(2)). Add a spouse or child online through VA.gov or on VA Form 21-686c. A child aged 18 to under 23 who is in school also needs VA Form 21-674, and a dependent parent is claimed on a different form, VA Form 21P-509 (VA.gov, add dependents).

Below 30%, the payment is the same whether you live alone or support a family of six, and that is why this gets missed. A veteran rated 20% adds nothing by reporting a spouse, learns that, and never revisits it. Years later the rating reaches 60% and the dependents are still not on the award.

Who counts as a dependent

• A spouse. Including a same-sex spouse, and generally including a common-law spouse where the state of residence recognises the marriage.
• Unmarried children under 18. Biological and adopted children, and stepchildren who are members of your household.
• Unmarried children aged 18 to under 23 in full-time school. These require separate certification on VA Form 21-674.
• An unmarried child of any age who became permanently incapable of self-support before turning 18. This can continue for life, for as long as the child stays unmarried and unable to support themselves.
• Dependent parents. Where a parent's own income is not enough to live on reasonably. VA sets income levels below which dependency is automatic, and above them it also looks at whether the parent's assets could reasonably cover their upkeep.

There is an additional allowance where a spouse requires aid and attendance, which is separate from and paid on top of the ordinary spousal rate.

How to add a dependent: step by step

1. Check your rating. The extra amount for a spouse, child, or dependent parent is payable only where your combined rating is 30 percent or more.
2. Gather the details. Dates of birth and Social Security numbers for each dependent; for a spouse, the marriage date and place; and where either of you was married before, the date and manner each prior marriage ended. VA generally accepts your own statement as proof of a marriage or a divorce, but only when it gives the month and year, the place, and the other person's full name and relationship to you (38 CFR § 3.204(a)).
3. Add a spouse or child. File online through your VA.gov account, or use VA Form 21-686c, Application Request to Add and/or Remove Dependents. VA encourages the online route and treats the day you start the online claim as the date it received the claim.
4. Add a child aged 18 to under 23 in school. Include VA Form 21-674, Request for Approval of School Attendance. VA removes children from the award at 18, so a child staying in school has to be submitted again.
5. Add a child who cannot support themselves. For a child who became permanently incapable of self-support before 18, VA.gov says to submit the child's private medical records about the disability with the application.
6. Add a dependent parent. Submit VA Form 21P-509, Statement of Dependency of Parent(s). VA.gov describes this form as sent by mail.

Who qualifies, in the regulations' words: a child must be unmarried and under 18, in school until 23, or permanently incapable of self-support from before 18 (38 CFR § 3.57), and a parent is a natural or adoptive mother or father, or someone who stood in a parent's place for at least a year before the veteran entered service (§ 3.59). For a parent, dependency is conclusive where monthly income does not exceed the amounts in § 3.250(a)(1). Above them, dependency is decided on the facts, and it is not held to exist if it is reasonable that part of the parent's estate be used for their upkeep (§ 3.250(a)(2)).

Effective dates, and the one-year rule

Dependency has its own effective date rule, generous if you act promptly and unforgiving if you do not.

Where you notify the VA within one year of the event, the marriage, the birth, the adoption, the additional payment is generally effective from the date of the event itself. Report it later than a year and the increase generally runs from the date the VA received your notice, and the intervening period is lost.

There is a parallel rule when the rating is what changed. If you were already supporting dependents and your rating is increased to 30% or above, the dependent rate should attach from the effective date of that rating, provided proof of the dependents is received within one year of the VA notifying you of that rating decision. That year runs from the rating notice, not from any VA request, so sending the 21-686c within it, whether or not a letter asking about dependents has arrived, is what protects the earlier date.

What it is actually worth

The additional amounts are set by the annual compensation rate tables rather than by a percentage, and they grow with the rating. For example, under the rates effective December 1, 2025, a veteran rated 60% receives $1,435.02 a month with no dependents, $1,566.02 with a spouse and no children or parents, and $1,663.02 with a spouse and one child and no parents. More children, a child over 18 in school, a dependent parent, and a spouse who receives aid and attendance each change the amount.

The current tables are published on VA.gov's compensation rates page, which is the authoritative source and is updated with each cost-of-living adjustment. The figures above are dated for that reason; check your own row on the table.

Because the allowance scales with the rating, it also quietly changes what an increase is worth. A veteran with three dependents gains more from moving 60% to 70% than a single veteran does, since the base rate and the dependent amounts step up together.

A rating that crossed 30% years ago

If your rating went from 20% to 40% at some point and nobody ever asked about dependents, or the letter arrived and went unanswered, check the award now. The current payment either includes the dependent rate or it does not, and the difference is visible on your award letter.

The checklist

1. Confirm your combined rating is 30% or higher. Below that, this changes nothing.
2. File VA Form 21-686c with marriage, birth, and prior-divorce details ready.
3. Add VA Form 21-674 for any child aged 18 to under 23 in full-time education, and keep the child's school information up to date with the VA.
4. Report additions within one year of the event to keep the earlier effective date.
5. Report removals immediately to avoid an overpayment debt.
6. Check an existing award if your rating crossed 30% at any point in the past.
