Military disability retirement pay you receive as a pension, annuity or similar allowance for an injury or sickness resulting from active service is not included in taxable income. The same treatment covers VA disability compensation and pension payments to veterans or their families, grants for homes designed for wheelchair living, grants for motor vehicles if you lost your sight or the use of limbs, and benefits under a dependent-care assistance program.
There is nothing to apply for. Leave these payments out of the income you report.
