For retirees and those approaching retirement, some of the most critical tax-planning decisions for 2026 must be finalized before the tax return is prepared. This distinction matters because tax preparation simply reports historical decisions that have already occurred, whereas proactive tax planning asks whether specific actions should still be completed before December 31.
With several months remaining in 2026, you have a valuable window to analyze the interaction among your IRA withdrawals, Roth conversions, required minimum distributions, Social Security benefits, and the enhanced federal deduction available to qualifying seniors.
A Roth conversion moves assets from a traditional IRA or other tax-deferred retirement accounts into a Roth IRA. The core trade-off of this strategy is straightforward: any previously untaxed amounts generally become taxable income in the year they are converted, as confirmed by the IRS.
In exchange, the funds enter the Roth system, where qualified distributions can eventually be tax-free, and Roth IRA owners are exempt from lifetime required minimum distributions.
Because of the immediate tax impact, both the size and the timing of a conversion are critical. For example, converting $100,000 simply because of the general idea that "Roth is better" can be a poor strategy if the additional income pushes you into an undesirable tax position. Instead, a conversion should be modeled alongside your other 2026 income.
When evaluating this option, consider these questions:
How much taxable income do you expect to report this year?
Will your income rise significantly when your mandatory RMDs begin?
Will the conversion affect other income-based tax benefits?
Do you need the converted funds for near-term spending?
What tax rate are you paying now compared to the rate you expect to pay later?
A partial conversion may sometimes prove more beneficial than an all-or-nothing decision.

Under current law, required minimum distributions generally begin at age 73 for affected retirement accounts. The IRS calculates your RMD by taking your prior December 31 account balance and dividing it by an applicable life-expectancy factor.
However, the most effective time to plan for RMDs is often several years before they actually begin. Once mandatory distributions start, retirees lose a degree of control over the amount of taxable retirement income appearing on their returns.
If you are in the window between retirement and your RMD starting age, you may have a period where your taxable income is temporarily lower. This temporary low-income window can potentially be used for:
Roth conversions
Planned IRA withdrawals
Capital-gain recognition
Charitable strategies
Other tax-bracket management
The goal is not necessarily to minimize this year's tax bill. Sometimes, paying tax intentionally at a known rate today can reduce your exposure to a less favorable tax rate later.
Taxpayers age 65 or older may qualify for a separate, enhanced federal deduction. For 2026, this deduction can be as much as $6,000 per eligible individual, or $12,000 on a qualifying joint return where both spouses are eligible. This deduction is available to qualifying taxpayers whether they itemize deductions or claim the standard deduction.
However, this enhanced deduction phases out as modified adjusted gross income rises above $75,000 for single taxpayers and $150,000 for joint filers.
This phase-out creates a critical planning interaction. A large Roth conversion or other discretionary income transaction may produce a tax benefit in one area while reducing your enhanced senior deduction in another. This does not mean the transaction should be avoided, but it does mean you should project your entire return before making a final decision.

Retirement income rarely comes from a single source. Instead, a household's cash flow might combine:
Social Security benefits
A pension
Traditional IRA distributions
401(k) distributions
Investment income
Capital gains
Rental income
These individual pieces interact dynamically. For example, increasing an IRA distribution can increase taxable income, affect the taxation of your Social Security benefits, change the value of deductions tied to income, and potentially impact other income-sensitive costs.
This is why retirement tax planning works better as a coordinated income strategy than as a series of isolated decisions. Before deciding how much to withdraw from an IRA, consider what other elements will appear on your return.
While some planning strategies can be handled when your tax return is prepared, others cannot. A Roth conversion intended for 2026 must actually occur during the 2026 calendar year. Furthermore, Roth conversions generally cannot be undone through recharacterization if you later decide the conversion was too large.
Waiting until late December can also lead to administrative delays, as custodians become busy and incomplete paperwork can stall transactions. Running a tax projection while there is still time to act is a far more reliable approach.
This projection can estimate:
Expected 2026 income
Capital gains and losses
Retirement distributions
Potential Roth conversions
Available deductions
Expected tax brackets
Estimated tax payments and withholding
Retirement planning is not just about how much money you have accumulated, but how efficiently that money can be converted into after-tax retirement income.
