Why do you think you need to amend a tax return for the Veterans Administration disability payments you received? VA disability payments are not reported on a tax return.
Or are you referring to this -
Disabled veterans may be eligible to claim a federal tax refund based on:
- an increase in the veteran's percentage of disability from the Department of Veterans Affairs (which may include a retroactive determination) or
- the combat-disabled veteran applying for, and being granted, Combat-Related Special Compensation, after an award for Concurrent Retirement and Disability.
