You have to stop SS if you have an income over the allowed amount. If social security finds out you have been recieving disability and working with out filing taxes and turning in your income. 1. you will have to pay that money back. 2. you could be charged if not and probably be fined but may also have jail time for defrauding the government.

You should have a SS case worker. Any income over 700. you have to tell them about. They deduct after that amount from your SS. After I think 6 months they will not give you SS. If you become disabled later you have to reapply.
