Can a person who receives social security receive money from oil and gas?

ALL MONEY that you receive must be declared to the Social Security Dept.

If it is a new asset or some income from any source whatever, or even a winning in a lottery it must be declared to Social Security ASAP.

Obviously if you won $200,000 from Tattersalls, your fortnightly Social Security benefits would be reduced. Of course if you put it in the bank or bought shares with it, then Social Security would easily find out about it. So you cannot cheat on them, nor should you even think about it.

Don't know how it is in other places around the world such as the answer above, but in the US, one can earn money while on social security. It depends on whether the individual has reached "full retirement age" as to whether and how much the earnings will be taxed. Check with your accountant.
