A couple in their early 70s is sitting on traditional IRAs they wish were smaller. Required minimum distributions<\/a> (RMDs) have kicked in, and each year those withdrawals push more of their Social Security into taxable territory, nudging them closer to the next Medicare premium bracket. They have been thinking about converting about $100,000 to their Roth IRAs to shrink the problem, but they keep stalling on the same fear: will they have to wait five more years before touching the converted money?<\/p>\n The good news is they each opened their Roth IRAs roughly 20 years ago. That single fact changes the whole conversation.<\/p>\n This question shows up often in retirement forums, usually phrased something like \u201cI\u2019m 70, I want to convert, but I heard there\u2019s a new five year clock every time.\u201d The worry is understandable. The rule has been written about so many different ways that even careful readers come away confused.<\/p>\n Why a Long-Seasoned Roth Changes the Math<\/p>\n For qualified, tax-free distributions, the IRS effectively treats all of a person\u2019s Roth IRAs as one account. The five year clock runs from the first Roth IRA ever opened. Once that timer is satisfied and the owner is at least 59\u00bd, money converted later is immediately available as a qualified distribution.<\/p>\n Wes Moss explained it on the May 5, 2026 Clark Howard Podcast<\/a>, saying, \u201cthe IRS treats all of your Roth IRAs [as] one\u2026 if you\u2019ve got one that\u2019s 20 years old, then you have the five year vintage already\u2026 even if you opened a new one\u2026 it still should be treated as that same age.\u201d<\/p>\n For this couple, the old Roths already carry the vintage. A $100,000 conversion this year drops into a Roth that, for IRS purposes, is already twenty years old. They could withdraw the converted funds the next day if they wanted to.<\/p>\n One precision point for younger investors: a separate five year clock attaches to each individual conversion, and it exists to police the 10% early withdrawal penalty for anyone under 59\u00bd. This couple is well past that age, so the second clock simply does not apply to them. Investors in their fifties should keep the two clocks separate.<\/p>\n The Social Security and Medicare Payoff<\/p>\n The reason this matters for Social Security is the tax torpedo<\/a>. When provisional income climbs past $32,000 for a married couple filing jointly, a portion of Social Security becomes taxable. Past $44,000, up to 85% of benefits get pulled into the tax return. Traditional IRA withdrawals and RMDs feed straight into that calculation. Roth withdrawals stay out of it.<\/p>\n
