When a veteran loses back pay, it is rarely dramatic. There is no villain — just a series of quiet, avoidable decisions that each move the effective date forward. Here are the traps I see most.
Re-filing instead of appealing
After a denial, starting a brand-new claim instead of appealing feels like a fresh start. It is not — it resets your effective date to the new filing and forfeits the months you had already banked. Appeal within the year and keep the original date.
Abandoning a claim
Missing a deadline, ignoring an evidence request, or skipping a C&P exam can cause a claim to lapse. Picking it back up later means a later date and less retro.
Ignoring secondaries and increases
Conditions caused by a service-connected disability, and worsening that justifies an increase, can carry effective dates that relate back. Leave them unclaimed and you leave that back pay behind.
The pattern is always the same: a forward-moving effective date. Guard it, and you guard your money.
