The First-Year RMD Double-Taxation Trap
The IRS offers a unique one-time concession for your initial RMD. When you reach age 73, you do not have to take your first distribution by December 31 of that same calendar year. Instead, the law allows you to delay your initial RMD until April 1 of the following year. While delaying that first payout sounds like a convenient way to buy time, doing so often triggers a costly financial changes at 73 tax trap.
If you delay your initial age 73 RMD to April 1 of the following year, you remain obligated to take your second RMD by December 31 of that same year. Pushing your first RMD into the next calendar year forces two full RMD withdrawals into a single tax return. Doubling your distribution income in one year can dramatically inflate your total taxable income, driving you into significantly higher tax brackets and triggering peak Medicare IRMAA surcharges two years later.
To illustrate this trap, examine how the math plays out when you choose to delay your initial withdrawal versus taking it on schedule:
- Option A (On-Time Distribution): You take your initial RMD of $38,000 in the year you turn 73 before December 31. In year two, you take your second RMD of $40,000 before December 31. You spread $78,000 of taxable income evenly over two separate tax years.
- Option B (Delayed Distribution Trap): You delay your first $38,000 RMD until March 30 of the year after turning 73. On December 15 of that same year, you take your second scheduled RMD of $40,000. You now report $78,000 of forced taxable income on a single tax return, potentially triggering higher marginal tax rates and elevated Medicare surcharges.
Evaluating your broader cash flow and running tax projections before delaying your initial RMD prevents you from falling into this costly tax trap unnecessarily.
