Adding a Spouse or Child on VA Form 21-686c

The 30 percent gate

3.4(b)(2) is the regulation. An additional amount of compensation may be payable for a spouse, child, and/or dependent parent where a veteran is entitled to compensation based on disability evaluated as 30 per centum or more disabling. Authority: 38 U.S.C. 1115.

VA.gov uses the same gate. You must be eligible for VA disability compensation, and you must have a combined disability rating of at least 30 percent. The 10 percent and 20 percent rows on the 2026 table say, in so many words, that those ratings do not increase for a dependent spouse, child, or parent. Current figures on that page: 10 percent is $180.42; 20 percent is $356.66. Those two numbers do not grow with family size.

If you are still waiting on a first rating, you can claim dependents on the original application. VA.gov says that if the combined rating comes in at 30 percent or more, eligibility for the add-on is considered automatically. If you already have 30 percent and you never listed the spouse or child, you file now.

Who counts as a dependent

VA.gov's current list:

• A spouse. VA recognizes same-sex and common-law marriages.
• A parent, if you are directly caring for them and their income and net worth are below a certain amount.
• An unmarried child (including adopted child or stepchild) who is under 18, or is 18 to 23 and enrolled in school full time, or became permanently disabled before age 18.

38 CFR 3.57 is the regulatory definition of child. In general, an unmarried legitimate child, a child legally adopted before 18, a stepchild who acquired that status before 18 and is a member of the veteran's household (or was at the veteran's death), or an illegitimate child, who is under 18, or who became permanently incapable of self-support before 18, or who after 18 and until completion of education or training (but not after 23) is pursuing a course of instruction at a VA-approved educational institution. "Educational institution" includes schools, colleges, technical institutes, universities, and home schools that comply with the state's compulsory-attendance law for kindergarten through grade 12.

A stepchild is a child of the veteran's spouse. 3.57(a)(4) says that for 38 U.S.C. 1115 additional compensation, "child" does not include a child adopted *out* of the veteran's family.

Dependent parents are a separate form: VA Form 21P-509, Statement of Dependency of Parent(s). VA.gov says you do not use 21-686c for parents.

The forms, with the names VA actually uses

VA Form 21-686c is titled Application Request to Add and/or Remove Dependents. The add-and-remove page also calls the paper version a Declaration of Status of Dependents. Same form number. Use the current PDF from VA.gov, not a copy from a forum.

For a spouse or a child under 18, 21-686c is the paper path. VA.gov prefers the online claim through eBenefits / VA.gov and treats the day you start the online claim as the date of receipt.

For a child 18 to 23 attending school full time, you need 21-686c and 21-674, Request for Approval of School Attendance. VA.gov is explicit on that pairing.

For a child found permanently incapable of self-support before 18, submit the private medical records that relate to that disability with the application.

38 CFR 3.204 lets VA accept your statement as proof of marriage, dissolution, birth, or death of a dependent if it includes the month and year and place of the event, the full name and relationship, and, if the child does not live with you, the name and address of the person who has custody. You must provide the dependent's Social Security number. VA can still demand the documentary classes in §§ 3.205 through 3.211 if you do not live in a state, the statement looks invalid, it conflicts with the record, or there is a reasonable indication of fraud or misrepresentation.

Photocopies are acceptable if VA is satisfied they are genuine and unaltered.

Do not invent a marriage or a child to move a rate. That is how an add-on becomes an overpayment.

When the extra compensation starts

VA.gov's current effective-date rules for a marriage, birth, or adoption:

VA may pay back to the date of the marriage, birth, or adoption if all of these are true:

• You already had a combined rating of at least 30 percent at the time of the event
• You file the dependent claim within a year of the marriage, birth, or adoption
• You respond within a year to any request for more information or evidence

If it has been more than a year, VA may not pay back to the event date. It may pay from the date it received the dependent claim or, in some cases, up to a year before that date.

VA.gov treats the day you start an online claim as the date of receipt. If you file paper first and then file online, back pay on an award can run from the original paper receipt date. VA.gov says payment begins within two weeks after approval. That is their processing statement, not a guarantee about your file.

If you claimed the dependent on the original compensation application and the rating comes in at 30 percent or more, the add-on is supposed to be considered with that award. If the dependent is missing from the decision, check the dependents list on eBenefits / VA.gov before you assume it was granted.

What the 2026 tables actually add

Fetched from VA.gov compensation rates, effective December 1, 2025, last updated December 2, 2025. These are table figures, not a promise that your award will match them. Your dependent status has to be established.

Veteran alone, no dependents: 30% $552.47; 40% $795.84; 50% $1,132.90; 60% $1,435.02; 70% $1,808.45; 80% $2,102.15; 90% $2,362.30; 100% $3,938.58.

With spouse, no parents or children: 30% $617.47; 40% $882.84; 50% $1,241.90; 60% $1,566.02; 70% $1,961.45; 80% $2,277.15; 90% $2,559.30; 100% $4,158.17.

The spouse difference at 30 percent is $65.00. At 100 percent it is $219.59. That is the table, not a sales pitch.

Veteran with one child only, no spouse or parents: 30% $596.47; 70% $1,910.45; 100% $4,085.43.

With one child and spouse, no parents: 30% $666.47; 70% $2,074.45; 100% $4,318.99.

Additional children and a spouse on Aid and Attendance use the added-amount rows on the same VA.gov table. The basic "spouse and 1 child" row already includes the first child. Confirm the live table before you quote a number. COLA changes the grid.

School-age 21-674, and the 18th birthday

VA.gov says it tracks the child's date of birth. When the child turns 18, the add-on stops unless you report full-time school enrollment. That is why 21-674 exists. Update school information when it changes. A silent 18th birthday is a common way to create an overpayment if a school add-on was assumed and never filed, or to lose a lawful add-on if the child is in school and nobody told VA.

3.57(a)(1)(iii) stops the school-child definition at age 23, and at completion of the course if that is earlier.

A child who became permanently incapable of self-support before 18 is a different category. That finding is its own evidence packet, not a school form.

Removing a dependent

Divorce, death, a child leaving the household (for a stepchild), and a child who is no longer in school all change the rate. VA.gov says to notify VA right away after a divorce and that you do not need to upload documents in that specific online path. If VA keeps paying a former spouse or a stepchild who no longer qualifies, the extra is an overpayment.

Both-veteran couples can each receive additional compensation for each other and for the children if each has a combined rating of at least 30 percent. VA.gov warns that those claims take longer.

FAQs

I am 20 percent. Can I add my spouse for extra pay?

Not for additional compensation. 3.4(b)(2) and the 2026 10 to 20 percent table require 30 percent or more. The spouse can still matter for other programs. This add-on does not apply at 10 or 20.

Do I need a marriage certificate?

3.204 lets VA accept a complete statement in many cases. VA can still demand documentary proof under 3.205 to 3.211. If you have the certificate, include it. It is faster than a development letter.

My child is 19 and in college. Is 21-686c enough?

No. VA.gov requires 21-686c and 21-674 for a child 18 to 23 in school full time.

If I file 11 months after the wedding, can the add-on start on the wedding date?

VA.gov says yes, if you already had a combined 30 percent at the time of the marriage and you respond in time to any evidence request. If you file after a year, the event date is usually lost.

What if I forget to remove an ex-spouse?

The extra compensation becomes an overpayment. Report the divorce. See the overpayment post for dispute versus waiver if a debt letter follows.

Does adding a spouse start CHAMPVA?

No. CHAMPVA is a separate program with a separate application and a different eligibility gate. See CHAMPVA versus VA health care.
