📅 For most people retiring now, the IRS sets a date when money in traditional IRAs and 401(k)s has to start coming out: 73 if you were born 1951 through 1959, 75 if you were born 1960 or later.
Each year after that, the IRS divides your December 31 balance by a factor for your age. Take a hypothetical retiree, Linda, 74 and single, with $650,000 in a traditional IRA. Her factor is 25.5, so she has to withdraw about $25,500, roughly 3.9% of the balance. The share climbs every year, to about 5% at 80 and 8.2% at 90.
That money hits your return as ordinary income whether you need it or not, and for retirees already receiving Social Security, it can push combined income past $34,000 single or $44,000 married filing jointly, making up to 85% of benefits taxable.
If it pushes modified adjusted gross income past $109,000 single or $218,000 joint, the Medicare surcharge known as IRMAA raises premiums two years later, starting around $1,148 a year per person. Those are the 2026 lines, and they move each year.
The money you control is the money outside those rules. Roth IRAs and Roth 401(k)s have no required withdrawals during your lifetime, and qualified Roth withdrawals don't count toward the income that decides Social Security tax or Medicare premiums.
Still working at 73? The 401(k) at your current job can usually wait until you retire, as long as you don't own 5% or more of the company. IRAs don't get that pass.
If you give to charity and you're 70½ or older, sending money straight from the IRA to the charity counts toward the required withdrawal and keeps up to $111,000 off your 2026 return.
Roth conversions in the years before your start age can shrink the balance the IRS will later force out, but they only pay off when the tax you pay now is worth the flexibility later.
Is your required withdrawal money you'd spend anyway, or money you'd rather leave alone?
