Form 21-686c · AI drafter + walkthrough

Add dependents — claim every dollar of retro back-pay

At 30% combined or higher, every dependent on your VA record adds to your monthly payment. The 1-year retro back-pay window is the most- missed money in VA benefits — vets routinely lose $5k–$30k by filing late. The drafter below classifies each dependent, computes the retro window per qualifying event date, and lists exactly what documents to attach.

File online if you can.

VA.gov has an online dependents form that auto-pulls your current record. PDF still works if the online system errors out. Direct link: va.gov/view-change-dependents.

What are you filing?
Dependents you’re adding

One row per dependent. Plain English is fine — the drafter classifies (“my wife” → spouse, “my mom on my insurance” → dependent parent).

Dependent 1

0 / 5000

Software template only. The 21-686c is filed at va.gov/view-change-dependents by you or by a VA-accredited rep — never paid through claim sharks. Always review with a rep before submission.

Who counts as a dependent

Spouse

Legally married, including same-sex. Common-law spouse counts in states that recognize common-law marriage. You attach a marriage certificate.

Child under 18

Biological, adopted, step-, or in your legal custody. Birth certificate or adoption decree.

Child 18-23 in school

Full-time student at an approved school. Form 21-674 (school attendance certification) is required and must be re-submitted each year the child is enrolled.

Child permanently incapacitated before 18

No upper age limit. Medical evidence of disability before the child’s 18th birthday is required. This is a higher-paying line of dependent than the basic schedule.

Dependent parent

Biological or adoptive parent whose income / net-worth falls below the VA’s dependency thresholds. Often missed. Form 21P-509 attaches.

Pitfalls vets hit

You only get the dependent bump at 30% combined or higher

Below 30%, dependents don’t change the monthly payment. The form is still worth filing because if a future condition pushes you over 30%, the dependent record is already on file and the bump is automatic.

Back-pay from marriage / birth date IS available

If you were already rated 30%+ when you married or your child was born, you can collect retroactive dependent payments back to that date — but only if you file 21-686c within ONE YEAR of the qualifying event. After one year, the effective date is the date the form is received, and the back-pay is gone.

School-age child requires the 21-674 every academic year

The VA does not assume continued enrollment. If you do not re-certify each fall, the dependent payment for that child will stop and you will get a debt letter for any months paid in error.

Stepchild requires proof of physical custody and financial support

A stepchild is not automatically a dependent. The VA wants either a court order or a sworn statement showing the child lives with you and you support them.

What to attach

  • • Marriage certificate (for a spouse)
  • • Birth certificate (for biological children)
  • • Adoption decree (for adopted children)
  • • Court order or sworn statement of physical custody (for stepchildren)
  • • Form 21-674 (for children 18-23 in school)
  • • Form 21P-509 + income/net-worth evidence (for dependent parents)
  • • Final divorce decree (if removing a former spouse)

Already rated 30%+ and not sure if dependents are on file? Run the rating estimator — it shows what your monthly payment SHOULD be with dependents added. If your actual deposit is lower, file 21-686c today.
