Today I talked with an SSDI specialist at Soc. Sec. She told me the following so I share it with you.

If you get a job and you earn over 850.00/month gross income that counts as a trial work period. You get 9 trial work periods over a 60 month span. They can be used in any combination you want in that time frame. You can earn as much as you want in those trials.

After you use your trial work periods, you can earn up to 1080.00/ month without effecting your benefit. If you earn even a dime more than that in a month you are considered substantially gainfully employed and lose your benefit. All-in-one must be reported during the first six days of the month directly after the month you earned it. Ex: Income for August gets reported between September 1-6. Once you report you have a job they will adjust your My Social Security account so you can report your income online.
