At 68, Tom Martinez faces a common retirement puzzle. His $1.8 million portfolio splits into a $1.2 million IRA and a $600,000 taxable brokerage account. He needs $85,000 annually and receives $32,000 from Social Security, leaving a $53,000 gap. Most retirees would reflexively tap the IRA first, thinking bigger equals better. That approach may overlook significant tax advantages.
The Tax Math That Changes Everything
The taxable account holds distinct strategic advantages. When selling stocks held longer than a year, the capital gains rate is just 15%—applied only to the gains, not the full value. If shares were purchased at $400,000 and grew to $600,000, only the $200,000 gain faces tax. The bill: $30,000 total, or 5% of the account value.
Compare that to IRA withdrawals. Every dollar comes out as ordinary income taxed at 22%. A $53,000 withdrawal costs $11,660 in federal tax, netting $41,340—forcing a larger withdrawal to cover the gap. The taxable account delivers $50,250 after selling $53,000 in appreciated stock. That $8,910 annual difference compounds over decades.
The Five-Year Window Before RMDs
At 73, Required Minimum Distributions kick in. A $1.2 million IRA will force roughly $45,000 in annual withdrawals whether the money is needed or not. Combined with Social Security, that pushes income to $77,000 before touching the taxable account—potentially triggering Medicare IRMAA surcharges of $70-$350 monthly per person.
Drawing from the taxable account first keeps the IRA smaller. A $1.2 million IRA at 73 generates $45,000 RMDs. If spent down to $900,000 by then, RMDs drop to $34,000—staying under IRMAA thresholds and preserving the 15% capital gains rate instead of bumping into the 24% bracket.
Flexibility for Real Life
When a roof needs replacing or health costs spike, the taxable account responds without tax penalties. IRA withdrawals before 59½ face penalties, and even after, they’re locked into ordinary income rates. The taxable account allows selling specific lots for tax-loss harvesting during market drops—turning a 20% decline into deductible losses. IRAs offer no such offset.
For estate planning, taxable accounts receive a step-up in basis at death. Heirs inherit the full value with zero capital gains tax due. The IRA passes as a tax liability—beneficiaries pay ordinary income rates on every withdrawal over 10 years.
The Withdrawal Strategy
Drawing $53,000 annually from the taxable account until 73, then blending RMDs with taxable account withdrawals to stay under $106,000 in combined income (the 24% bracket threshold), presents several advantages. This approach preserves the IRA for later years while maximizing the taxable account’s 15% rate advantage. The smaller account isn’t just useful—it represents a key component of an effective tax strategy.
