What is the Alleged Onset Date of Disability (AOD)?

This is the date you told SSA you became unable to work.  If you have worked fairly
continuously, the AOD is typically the date you last worked.  You can allege any date
you desire; however, the ultimate determination of the correct AOD will relate to when,
again, objective longitudinal medical evidence which supports a possible
determination of disability.  

Some things that can suggest a later AOD than the one you initially chose can include
prior applications decided unfavorably that cannot be re-opened (if you have had prior
denied applications, you should always explore re-opening those with your lawyer or
SSA), intervening work activity at SGA, or the application is for SSI.  SSI applications are
paid from the application date (which can be a prior re-opened application) regardless
of the AOD in the application.  

A point to make about the AOD is that DDS will typically only obtain medical evidence
related to your claim after the AOD.  This is logical in most cases because that is the
date you said you became unable to work.  In some instances, though, a claimant’s
impairment is based on an event such as an automobile accident that occurred before
the AOD.  If there is no evidence of that in the file, the claimant should try to obtain
supporting evidence such as a police report, emergency room treatment and so on.
