Why Tax Planning Matters More in Retirement Than People Expect
Most retirees expect their tax burden to drop substantially when they stop working. For many, it doesn't.
The reasons are structural. Working income comes from one or two sources and follows a predictable annual pattern. Retirement income often comes from five or six sources — Social Security, pensions, IRA withdrawals, 401(k) or 403(b) withdrawals, taxable account distributions, sometimes part-time work or rental income — and each is taxed differently. Total taxable income can look quite similar to working years, particularly once Required Minimum Distributions begin.
For Columbus-area retirees, the planning picture also includes Ohio income tax, federal Social Security taxation, Medicare IRMAA surcharges, and capital gains decisions in taxable accounts. Each one interacts with the others.
The pattern that tends to produce the best results: treating retirement tax planning as a multi-year, multi-decision system rather than an annual filing exercise. The best decisions are often made years before their tax effects appear — a Roth conversion in a low-income year before Social Security begins, for example, can affect tax brackets and IRMAA tiers for the next twenty or thirty years.
How Retirement Income Is Taxed in Ohio
Ohio's tax framework starts with federal adjusted gross income and applies state-specific adjustments, deductions, and credits. The result is a state tax picture that's generally moderate compared to higher-tax states, with several retiree-specific features worth understanding.
Pension and retirement account income: OPERS, STRS, and private pension income — along with IRA, 401(k), 403(b), and 457 plan withdrawals — is generally included in Ohio adjusted gross income and subject to Ohio income tax.
Social Security: Ohio does not tax Social Security benefits, even when they're federally taxable. This is a meaningful advantage compared to states that tax Social Security.
Retirement income credit: Ohio offers a retirement income credit for qualifying retirement income, with limits that phase out at higher income levels. The credit amount is modest relative to a full pension's annual income but worth claiming when eligible.
State estate tax: Ohio has no state estate tax and no inheritance tax. Federal estate tax may still apply to larger estates, but the state-level question is simpler than in many states.
For a comprehensive walkthrough of how Ohio taxes retirement income across all its forms, see our forthcoming piece on how retirement income is taxed in Ohio (coming soon in this series).
Federal Taxation of Retirement Income
Federal taxation of retirement income is generally more consequential than state taxation for most retirees, simply because federal brackets are higher and more sensitive to income changes.
The categories that drive federal taxable income in retirement:
- Pension income — fully taxable as ordinary income at the federal level
- Traditional IRA, 401(k), 403(b), and 457 withdrawals — taxable as ordinary income
- Social Security benefits — federal taxation depends on combined income, with up to 85% of benefits potentially taxable in higher-income situations
- Taxable account distributions — interest taxed as ordinary income; qualified dividends and long-term capital gains taxed at preferential rates
- Capital gains — on appreciated investments held more than a year, taxed at long-term capital gains rates that are lower than ordinary income rates
The interaction matters. Drawing from a traditional IRA in a year when Social Security is also being received can push a retiree into a higher tax bracket and increase the federally taxable portion of Social Security. Strategic withdrawal sequencing across account types can manage this effectively over multi-year periods.
Roth Conversion Strategies
A Roth conversion moves money from a traditional IRA or 401(k) to a Roth IRA, paying ordinary income tax on the converted amount now in exchange for tax-free withdrawals later. For Ohio retirees, Roth conversions can be a powerful tool — but they require careful coordination with the rest of the tax picture.
The situations where Roth conversions tend to be most valuable include early retirement years before Social Security begins (income is typically lower), the gap years before Required Minimum Distributions start, years with lower-than-usual income for other reasons, and situations where leaving Roth assets to heirs is part of the estate strategy.
The factors that complicate the analysis: Ohio income tax on the converted amount, federal Social Security taxation if benefits have started, Medicare IRMAA surcharges triggered by higher conversion-year income, and the long-term return assumptions that drive whether a conversion produces net tax savings.
Roth conversions also need to be evaluated against the federal estate tax outlook, future tax law expectations (rates may change), and the retiree's expected drawdown pattern. We cover this in detail in our forthcoming piece on Roth conversion strategies for Ohio retirees (coming soon in this series).
Required Minimum Distributions and Tax Planning
Required Minimum Distributions (RMDs) are mandatory annual withdrawals from traditional IRAs, 401(k)s, 403(b)s, and similar accounts that begin at the age specified in current tax law. For retirees with substantial tax-deferred balances, RMDs can become one of the largest sources of taxable income later in retirement.
The planning challenge: by the time RMDs begin, the planning window for managing them has largely closed. The most effective RMD planning happens in the years before RMDs start, when withdrawal strategies, Roth conversions, and charitable giving approaches can shape what the RMD picture eventually looks like.
The areas that interact with RMD planning include current tax bracket vs. expected future bracket, Social Security claiming timing, charitable giving plans, estate planning goals, spouse's income and account balances, and total household tax-deferred balances.
A retiree with $1.5 million in traditional IRA assets faces a different RMD picture than one with $500,000. The strategies that make sense scale accordingly. We cover the specifics in our forthcoming piece on Required Minimum Distributions and tax planning (coming soon in this series).
Medicare IRMAA and Income Management
Medicare IRMAA — the Income-Related Monthly Adjustment Amount — is one of the most consequential and least-understood elements of retirement tax planning. IRMAA increases Medicare Part B and Part D premiums when income exceeds certain thresholds.
The mechanic that catches retirees off guard: IRMAA is based on income from two years prior. A large income event in one year — a Roth conversion, a real estate sale, an investment liquidation — affects Medicare premiums two years later. By the time the premium adjustment shows up, the planning window for that year is closed.
The income sources that count toward IRMAA include pension income, IRA and 401(k) withdrawals, Roth conversions, capital gains, interest and dividends, and taxable portion of Social Security. Roth IRA qualified withdrawals don't count toward IRMAA, which makes Roth balances particularly valuable for income management in higher-income years.
Common situations that produce IRMAA surprises:
- A large Roth conversion in a single year rather than spread across multiple years
- Selling a primary residence and capturing capital gains above the exclusion
- Selling appreciated investments with significant capital gains
- Taking a large lump-sum distribution
- A spouse's income event in a household-filing situation
Tax planning and IRMAA planning should always be reviewed together. We walk through the specifics in our forthcoming piece on Medicare IRMAA: how to avoid the surcharge (coming soon in this series).
Tax-Efficient Withdrawal Order
The order in which retirees draw from different account types can meaningfully affect lifetime tax exposure. The general framework involves three account categories:
Taxable accounts — brokerage accounts, savings, CDs. Withdrawals don't trigger taxes directly (basis returns aren't taxed), and gains qualify for long-term capital gains treatment when held more than a year.
Tax-deferred accounts — traditional IRAs, 401(k)s, 403(b)s, 457s. Withdrawals are taxed as ordinary income. These accounts also drive Required Minimum Distributions.
Tax-free accounts — Roth IRAs, Roth 401(k)s. Qualified withdrawals are tax-free and don't count toward IRMAA.
The conventional withdrawal order is taxable first, tax-deferred next, Roth last — but that's a starting point, not a rule. The right answer depends on tax bracket management, IRMAA threshold proximity, Social Security claiming timing, expected longevity, and estate planning goals.
A retiree who needs to manage income carefully to stay under an IRMAA threshold might draw more from Roth and taxable in those years. A retiree with a long expected retirement and meaningful tax-deferred balances might benefit from Roth conversions in early retirement to manage future RMDs.
There's no universal best order. The right strategy is one that's evaluated annually based on the retiree's specific situation. Our forthcoming piece on tax-efficient withdrawal order for retirees (coming soon in this series) covers the framework in detail.
Charitable Giving Strategies
For Ohio retirees who want to support charitable causes, two strategies can meaningfully reduce taxable income while increasing the impact of giving: Qualified Charitable Distributions (QCDs) and Donor-Advised Funds (DAFs).
Qualified Charitable Distributions allow retirees of qualifying age to donate directly from a traditional IRA to a qualified charity. The donation counts toward Required Minimum Distributions but doesn't appear in taxable income — meaning it doesn't increase Ohio adjusted gross income, push Social Security into higher taxation tiers, or affect Medicare IRMAA thresholds. QCDs can be especially valuable for retirees who don't itemize deductions, since the tax benefit comes through reduced income rather than through itemized deductions.
Donor-Advised Funds allow retirees to contribute appreciated assets (often appreciated investments from a taxable account) and receive an immediate charitable deduction, then direct grants to charities over future years. This strategy works particularly well for "bunching" multiple years of giving into a single high-income year for itemization purposes.
These two strategies aren't mutually exclusive. Many retirees use QCDs for ongoing annual giving and DAFs for larger one-time or strategic giving. We cover both in our forthcoming piece on charitable giving strategies: QCDs and DAFs explained (coming soon in this series).
Capital Gains Planning in Retirement
Taxable accounts that have grown over decades often hold significant unrealized capital gains. How those gains are realized in retirement affects tax exposure substantially.
The planning areas include holding period management (long-term capital gains rates are preferential), tax-loss harvesting to offset gains, asset location strategy (which assets are held in which account type), step-up in basis at death for inherited assets, and the interaction between capital gains and IRMAA tiers.
Capital gains decisions also interact with Roth conversion timing, charitable giving (donating appreciated assets to DAFs eliminates the capital gains tax), and broader estate planning. A retiree with appreciated investments held outside retirement accounts has more planning flexibility than one with assets primarily in tax-deferred accounts — and that flexibility should be used deliberately rather than randomly.
We cover capital gains strategy in detail in our forthcoming piece on capital gains planning in retirement (coming soon in this series).
How These Pieces Fit Together
The tax planning areas above don't sit in silos. They interact in ways that aren't obvious until you model them together.
A Roth conversion this year affects taxable income this year, which affects IRMAA in two years, which affects healthcare costs, which affects withdrawal needs from other accounts. Reducing RMDs in the future through Roth conversions today affects estate planning, which interacts with charitable giving strategy, which affects taxable income management again.
For Columbus retirees, the practical implication is that retirement tax planning is best handled as an integrated, multi-year process rather than as a series of one-off decisions made at filing time. The decisions made in the years before retirement — and in the early years of retirement — often shape tax outcomes for the next two or three decades.
This is one of the areas where coordinated planning between a financial advisor and a tax professional adds the most value. The advisor handles the multi-year modeling and decision sequencing; the tax professional handles the specific advice and preparation. They work together rather than in isolation.
Frequently Asked Questions
Are retirement distributions taxed in Ohio? Most retirement distributions are subject to Ohio income tax if they're included in federal adjusted gross income. This includes pension income, IRA withdrawals, and 401(k)/403(b)/457 distributions. Ohio does not tax Social Security benefits, and a retirement income credit may apply to qualifying income at lower income levels.
Does Ohio have a state estate tax or inheritance tax? No. Ohio has no state estate tax and no state inheritance tax. Federal estate tax may still apply to larger estates.
What is Medicare IRMAA? IRMAA is the Income-Related Monthly Adjustment Amount — a surcharge added to Medicare Part B and Part D premiums for retirees whose income exceeds certain thresholds. IRMAA is based on income from two years prior, so income decisions today affect Medicare premiums two years later.
When is a Roth conversion worth considering? Roth conversions can be valuable in lower-income years, before Required Minimum Distributions begin, or when leaving Roth assets to heirs is part of the estate plan. Conversions need to be evaluated against federal taxes, Ohio taxes, Social Security taxation effects, Medicare IRMAA tiers, and future RMD projections. A tax professional should review specific situations.
What's the difference between a QCD and a DAF? A Qualified Charitable Distribution (QCD) is a direct transfer from a traditional IRA to a qualified charity that can count toward Required Minimum Distributions without increasing taxable income. A Donor-Advised Fund (DAF) is an account that accepts contributions (often appreciated assets) for which the donor receives an immediate tax deduction, with grants directed to charities over time. Both can play roles in a coordinated giving strategy.
Do I need a tax professional and a financial advisor? Many retirees benefit from having both. A tax professional handles preparation and specific tax advice. A financial advisor handles multi-year planning, withdrawal coordination, and how tax decisions fit into the broader retirement plan. The two roles complement each other when they communicate, and the value typically comes from working together rather than separately.
When should retirees start tax planning for retirement? The most valuable tax planning often happens in the years before retirement and in the early years after, when income is typically lower and there's the most flexibility around Roth conversions, charitable timing, and withdrawal strategy. Starting tax planning at retirement is good. Starting in the 3-5 years before retirement is better.
Does Ohio tax 401(k) and IRA withdrawals? Yes. Withdrawals from traditional 401(k)s, IRAs, 403(b)s, and 457 plans are generally included in Ohio adjusted gross income and subject to Ohio income tax. Roth withdrawals that meet qualified distribution requirements are generally not federally taxable and are also not added back into Ohio taxable income.
Build a Tax Plan Before You Need One
Tax-efficient retirement in Ohio isn't about finding loopholes or maximizing deductions in any single year. It's about coordinating multiple decisions across the full retirement period so that taxes are managed strategically rather than reactively.
For Columbus-area retirees and pre-retirees, the questions worth thinking through include: How will my federal and Ohio tax picture change after retirement? When might Roth conversions make sense, and over what timeframe? What will my Required Minimum Distributions look like, and how can I shape them now? How do my income decisions affect Medicare IRMAA? How can charitable giving fit into my tax strategy? What's the right withdrawal order across my accounts?
These questions don't have universal answers — they have answers specific to each household's situation. But they're best worked through with a coordinated plan, ideally well before retirement begins.
