Retirement Tax Planning: 5 Vital Moves to Make Before December 31
For retirees and those approaching retirement, some of the most critical financial decisions of 2026 must be finalized long before your tax return is prepared.
That distinction between preparation and planning is essential. Tax preparation simply reports decisions that have already taken place. Conversely, proactive tax planning evaluates whether you should execute specific strategies before the December 31 deadline to optimize your long-term position.
With several months remaining in 2026, retirees and pre-retirees have a valuable opportunity to analyze how traditional IRA withdrawals, Roth conversions, required minimum distributions, Social Security benefits, and the enhanced federal deduction for seniors interact. Let's explore five key areas to evaluate with our team at Cherokee CPA.
1. Evaluate the Merits of a Roth IRA Conversion
A Roth conversion involves moving assets from a traditional IRA or another tax-deferred retirement account into a Roth IRA.
The core tradeoff is straightforward: any previously untaxed funds generally become part of your taxable income in the year of the conversion. In exchange, the money shifts into the Roth system, where qualified distributions are tax-free and the account owner is exempt from lifetime required minimum distributions (RMDs).
The IRS treats untaxed assets converted from a traditional retirement account to a Roth IRA as taxable income for the conversion year. This makes managing both the size and the timing of your conversion incredibly critical.
For example, converting $100,000 simply because you believe a Roth account is inherently better can be a costly mistake if that extra income pushes you into an unfavorable tax bracket. Instead, a conversion should be carefully modeled alongside your other projected 2026 income.
Key questions to consider include:
- How much total taxable income do you expect to report this year?
- Will your tax bracket increase once mandatory distributions begin?
- Will a conversion negatively impact other income-based tax benefits or deductions?
- Do you need to access the converted assets for near-term spending needs?
- How does your current marginal tax rate compare to the rate you anticipate paying in the future?
In many cases, executing a partial Roth conversion makes far more financial sense than an all-or-nothing approach.
2. Plan for Required Minimum Distributions Years in Advance
Under current law, required minimum distributions (RMDs) generally begin at age 73 for affected retirement accounts. The IRS calculates your RMD by dividing your prior December 31 account balance by an applicable life-expectancy factor.
However, the best time to formulate your RMD strategy is actually several years before these mandatory distributions are legally triggered.
Once your RMDs begin, you have significantly less control over the amount of taxable income that must appear on your annual tax return. The transitional window between your actual retirement and the start of your mandatory distributions represents a unique planning opportunity. When your taxable income is temporarily lower, you have a strategic window to execute several valuable tax-bracket management strategies:
- Systematic Roth conversions
- Planned traditional IRA withdrawals
- Recognizing capital gains at lower tax rates
- Implementing charitable giving strategies
- Other structured bracket-management techniques
The goal here is not necessarily to minimize your tax liability for the current year. Sometimes, choosing to pay tax intentionally at a known, lower rate today can successfully reduce your exposure to less favorable tax rates in the future.
3. Assess the Rules for the Enhanced Senior Deduction
Taxpayers who are 65 or older may qualify for an additional enhanced federal deduction. For the 2026 tax year, this standard deduction add-on can be as much as $6,000 per eligible individual, or $12,000 when both spouses on a qualifying joint return are eligible.
This enhanced deduction is available to qualifying taxpayers whether they choose to claim the standard deduction or itemize their deductions.
However, this tax benefit begins to phase out once modified adjusted gross income (MAGI) rises above $75,000 for single filers and $150,000 for joint taxpayers.
This phase-out creates a highly important planning interaction. Executing a large discretionary transaction—such as a major Roth conversion or a significant retirement account withdrawal—might offer a long-term tax benefit, but it could simultaneously reduce or eliminate your enhanced senior deduction for 2026. This highlights why it is critical to project your entire tax return before committing to any year-end moves.
4. Coordinate Your Social Security with Other Income Sources
Retirement cash flow rarely arrives from a single source. A typical household's retirement income is often composed of multiple distinct streams, including:
- Social Security benefits
- Employer pensions
- Traditional IRA withdrawals
- 401(k) distributions
- Taxable investment interest and dividends
- Capital gains
- Rental real estate income
These components are interconnected. For example, increasing a traditional IRA withdrawal raises your adjusted gross income, which can subsequently trigger or increase the taxation of your Social Security benefits, reduce the value of income-sensitive deductions, or increase other income-based expenses.
This is why effective retirement tax planning works best as an overall, comprehensive income strategy rather than a series of isolated decisions. Before deciding on the specific amount to withdraw from your retirement accounts, you must model how that withdrawal will interact with every other line item on your return.
5. Run a Detailed Tax Projection Well Before December
While some financial strategies can be handled during springtime tax preparation, others must be completed long before the year ends.
A Roth conversion intended for the 2026 tax year must actually occur within the 2026 calendar year. Furthermore, Roth conversions cannot be undone through recharacterization if you later decide the conversion amount was too large. Waiting until the final weeks of December also introduces administrative risks, as custodians experience year-end backlogs or paperwork processing delays.
A more strategic approach is to run a comprehensive tax projection while you still have ample time to act. This projection allows us to estimate:
- Your total expected 2026 income
- Projected capital gains and offsetting capital losses
- Scheduled retirement account distributions
- Potential Roth conversions
- Your available tax deductions
- Your projected tax brackets
- Your estimated tax payments and withholding levels
Retirement planning is not just about the size of the nest egg you accumulate. It is also about the efficiency with which you convert those assets into usable after-tax retirement income.
