How long do I have to wait after becoming disabled before I can file for Social Security disability benefits?

Not even one day. You can file for Social Security disability benefits on the very same day that you become disabled. Many individuals make the mistake of waiting months and even years after becoming disabled before filing a Social Security disability claim. There is no reason to file a Social Security disability claim if one has only a minor illness or one which is unlikely to last a year or more. However, an individual who suffers serious illness or injury and expects to be out of work for a year or more should not delay in filing a claim for Social Security disability benefits.
