Here are some timelines for Social Security Disability applications:
Initial Applications:
6 months: If you’re approved or benefits, you’ll get a lump sum payment starting from six months after Social Security deems your disability officially started to the present day. After that, you’ll start receiving a monthly check.
60 days: If your initial application is denied, you’ll have 60 days to file for an appeal. Then you’ll again need to wait for an answer.
