They always want your money back for the month you die in. This from the SS website:

"If the deceased was receiving Social Security benefits, you must return the benefit received for the month of death or any later months. For example, if the person dies in July, you must return the benefit paid in August. If benefits were paid by direct deposit, contact the bank or other financial institution. Request that any funds received for the month of death or later be returned to Social Security. If the benefits were paid by check, do not cash any checks received for the month in which the person dies or later. Return the checks to Social Security as soon as possible.

However, eligible family members may be able to receive death benefits for the month in which the beneficiary died. "
