In-Retirement Tax Optimization: Withdrawal Strategy and RMD Planning

Now that you're retired, the focus shifts to drawing down your accounts tax-efficiently, managing RMDs, and capturing Roth conversion opportunities in lower-income years before age 73. Annual coordination across withdrawals, conversions, and IRMAA is critical.

The key decisions now:

• Which accounts to pull from first. The textbook sequence is taxable, then tax-deferred, then Roth. But pulling from tax-deferred accounts early -- before required minimum distributions start at age 73 -- can keep you in lower brackets long-term.
• Managing RMDs. Once required minimum distributions begin, they're mandatory and taxable. Large tax-deferred balances can push you into higher brackets and trigger Medicare IRMAA surcharges.
• Roth conversions in lower-income years. If you're retired but haven't reached 73, you may be in temporarily lower brackets. Converting traditional IRA money to Roth locks in lower rates and reduces future RMDs.
• IRMAA awareness. Medicare premiums rise at specific income thresholds. A large capital gain or aggressive Roth conversion can cost thousands in surcharges two years later, when that income shows up on the return Medicare uses.

What a CPA coordinates: They model the interaction between withdrawals, conversions, RMDs, and IRMAA across multiple years -- not just the current return.

The tradeoff: If you've been retired for years without this planning, some Roth conversion opportunities in lower brackets may have passed. A CPA can assess what's still available.
