IF you retired early at 62 on Social Security, How best to obtain ANY additional S.S. to your monthly check?

If you earn wages or self-employment income after starting Social Security, that income is used to re-compute your benefit each year. This is true no matter how old you are. However, in any year before full retirment age, you will have to pay back $1 for every $2 you earn over the yearly limit (currently $15,720).

You can also look into reduced Medicare premiums if you receive Medicare. Low income individuals may qualify for reduced premiums, which will raise the amount you receive monthly from SS because you will pay less for Medicare.

Go back to work. There's a Catch-22 though. Earn more than $15,720 and you'll lose $1 of benefits for each $2 over that amount. The upside to that is that the amount lost will be taken into consideration when you reach full retirement age and your benefit will be increased at that time.

There are none unless some sort of medical issue an be claimed but only an expert could answer any questions. Once started, that is it.

Wait for next year's cost of living adjustment. (Don't expect much.)

You can't unless you go back to work.

Probably, growing perennial plants & selling them at your local flea market.
