Back pay is the lump sum the VA owes you from your effective date to the day it finally grants your claim. It can be substantial — and I have watched veterans give away years of it through avoidable mistakes.
The mistakes that cost the most
- Filing late without an Intent to File to protect the date
- Dropping an appeal and re-filing later, resetting the effective date to the new claim
- Missing the one-year appeal window and losing the original date
- Not claiming secondaries that relate back to the original condition
Guard the date
Every one of these mistakes has the same effect: it moves your effective date forward and shrinks your back pay. The defense is simple in principle — file early, appeal on time, and never abandon a claim you can continue. The date is money. Protect it like money.
