Investing for a 65-Year-Old

At age 65, Medicare Part A and B enrollment is mandatory unless you have qualifying employer group coverage. Enrolling in Part A, even without Part B, disqualifies you from making new HSA contributions immediately; plan your final HSA deposit for the months before enrollment. Social Security at 65 pays less than your full retirement age benefit (67 for those born 1960 or later), so weigh the two additional years of delay against break-even timelines. Required minimum distributions do not begin until age 73 (if born 1951-1959) or 75 (if born 1960 or later), giving your tax-deferred accounts more compounding time.
