Retirement Tax Strategy: Roth Conversions, RMDs, and Withdrawal Sequencing

Most retirement planning focuses on how much you save. Far less attention goes to how much of it you actually keep. The IRS Uniform Lifetime Table, the SECURE 2.0 Act’s required minimum distribution schedule, and the order in which you draw down accounts can each move your lifetime tax bill by tens of thousands of dollars, and none of it depends on picking better investments. It depends on sequencing decisions you make with the accounts you already have.

This guide covers five levers that account for most of the controllable tax cost in retirement: Roth conversion timing, tax-loss harvesting in taxable accounts, the required minimum distribution rules SECURE 2.0 changed, the order you draw from taxable, tax-deferred, and Roth accounts, and how physical precious metals are taxed differently depending on whether they sit inside or outside an IRA. Every figure below is grounded in IRS Publication 590-A, IRS Publication 590-B, or the underlying statute, cited by name so you can verify it directly.

Why Tax Strategy Is a Separate Discipline From Investment Selection

Two retirees with identical portfolios and identical returns can end up with meaningfully different after-tax wealth, purely because one coordinated withdrawals and conversions and the other didn’t. The tax code treats a dollar earned on a stock sale, a dollar withdrawn from a traditional IRA, and a dollar withdrawn from a Roth IRA in three entirely different ways, and the difference compounds every year it goes unmanaged.

The core problem is that most of these decisions are made in isolation. A Roth conversion decided without reference to Medicare premium thresholds, an RMD taken without reference to the accounts sitting beneath it, or a tax-loss harvest executed without reference to the wash-sale rule all leave money on the table. A coordinated strategy treats these as one connected system rather than five separate chores.

Roth Conversion Planning: Paying Tax Now to Avoid a Larger Bill Later

A Roth conversion means moving money from a traditional IRA or 401(k), where it has never been taxed, into a Roth IRA, where withdrawals in retirement are tax-free. You pay ordinary income tax on the converted amount in the year you convert, and in exchange the balance grows without any future tax owed on withdrawal, according to IRS Publication 590-A.

The strategic case for converting rests on timing, not on some fixed rule that conversions are always good. A conversion executed in a year when your taxable income is unusually low, such as the gap between retiring and claiming Social Security or between retiring and your first RMD, lets you move money at a lower marginal rate than you would otherwise pay later. Converting the same dollar amount in a peak-earning year, or in a year already crowded by RMDs, can push you into a materially higher bracket for no strategic benefit.

Three mechanical rules govern how conversions actually work.

No income limit applies. Unlike Roth IRA contributions, which phase out at higher income levels, conversions have no income ceiling. Anyone with a traditional IRA balance can convert, regardless of earnings.
The pro-rata rule applies to mixed IRAs. If you hold both pre-tax and after-tax (nondeductible) contributions across your traditional IRAs, the IRS treats a conversion as a proportional slice of both, not as your after-tax dollars first. This is calculated on Form 8606 and applies across all traditional, SEP, and SIMPLE IRAs you own, aggregated together, per IRS Publication 590-A.
Conversions cannot be undone. Since the Tax Cuts and Jobs Act eliminated recharacterization in 2018, a completed Roth conversion is final. If the market drops sharply after you convert, you still owe tax on the higher, pre-drop value.

Each conversion also starts its own five-year clock. Converted principal can be withdrawn without penalty at any time, but the earnings on a conversion are only penalty-free once five tax years have passed and you are past 59½, per IRS Publication 590-B. Someone doing several conversions across different years is tracking several separate five-year clocks, not one.

Tax-Loss Harvesting: What the $3,000 Limit Actually Means

Tax-loss harvesting means selling an investment at a loss in a taxable brokerage account to offset capital gains realized elsewhere, reducing the tax owed for the year. It only applies to taxable accounts. Losses inside a traditional or Roth IRA are not deductible under any circumstance, because the IRS does not tax IRA gains as they occur in the first place, per IRS Publication 590-B.

Realized losses first offset realized capital gains dollar for dollar within the same tax year. Once gains are fully offset, up to $3,000 of remaining losses ($1,500 if married filing separately) can be deducted against ordinary income annually. Any loss beyond that carries forward to future tax years indefinitely, according to IRS guidance on capital gains and losses (Topic No. 409). A large single-year loss is rarely wasted. It’s simply spread across multiple future tax returns.

Two rules limit how aggressively this strategy can be used.

The wash-sale rule. If you sell a security at a loss and buy a substantially identical one within 30 days before or after the sale, the IRS disallows the loss under IRC Section 1091. The disallowed loss gets added to the cost basis of the replacement position rather than lost outright, but it cannot be claimed in the current year.
The collectibles rate on physical metals. Physical gold, silver, platinum, and palladium held in a taxable account (not inside an IRA) are classified as collectibles under IRC Section 408(m). Long-term gains on collectibles are taxed at a maximum rate of 28%, not the standard 0/15/20% long-term capital gains brackets that apply to stocks and funds. That 28% is a ceiling, not a flat rate. If your ordinary marginal rate is below 28%, the gain is taxed at your ordinary rate. If it’s above, the rate is capped at 28%. Losses on physical metals held in a taxable account can still be harvested under the same $3,000 annual rule described above.

Required Minimum Distributions: What SECURE 2.0 Actually Changed

A required minimum distribution is the minimum amount the IRS forces you to withdraw from a traditional IRA or 401(k) each year once you reach a set age, calculated by dividing your prior year-end account balance by a life-expectancy factor from the IRS Uniform Lifetime Table in Publication 590-B. The SECURE 2.0 Act raised the starting age twice, and the phase-in schedule is where most confusion sits.

Birth Year	RMD Starting Age
1950 or earlier	72
1951 to 1959	73
1960 or later	75

The age-73 threshold took effect in 2023. The age-75 threshold takes effect in 2033. Between now and then, anyone born 1951 through 1959 follows the age-73 rule, per the SECURE 2.0 Act of 2022 (Public Law 117-328), Section 107.

Three practical details matter more than the age itself.

The first RMD can be delayed, at a cost. You can wait until April 1 of the year after you reach your RMD age to take your first distribution, but doing so means taking two RMDs in that same calendar year, which can push you into a higher bracket. Most people are better off taking the first RMD in the year they reach the threshold.
The penalty for missing an RMD dropped, but it’s still real. Before SECURE 2.0, the excise tax on a missed or short RMD was 50% of the shortfall. SECURE 2.0 cut that to 25%, and to 10% if the shortfall is corrected within two years, per IRS Publication 590-B.
Roth accounts are exempt during the owner’s lifetime. Roth IRAs have never been subject to lifetime RMDs. SECURE 2.0 extended that same exemption to Roth 401(k) and Roth 403(b) accounts starting in 2024, removing a long-standing inconsistency between Roth IRAs and Roth employer plans.

A Qualified Charitable Distribution, or QCD, is worth knowing here even though it’s technically a deduction strategy, not an RMD rule. Once you’re 70½, you can direct up to an annually indexed limit (it started at $100,000 in 2023 and rises with inflation each year) directly from a traditional IRA to a qualified charity. The distributed amount counts toward satisfying your RMD but is excluded from taxable income entirely, which is a materially different outcome than taking the RMD and then donating the after-tax proceeds, per IRS Publication 590-B.

Withdrawal Sequencing: The Order You Draw From Accounts Changes What You Owe

Withdrawal sequencing is the order in which you draw from taxable, tax-deferred, and Roth accounts in retirement, and it changes your lifetime tax bill independent of how much you actually spend. The conventional default sequence is taxable accounts first, tax-deferred accounts second, and Roth accounts last.

The logic behind that order is straightforward. Taxable account withdrawals only trigger tax on the gain, not the full balance, since the principal was already taxed when earned. Tax-deferred withdrawals are taxed in full at ordinary income rates. Roth withdrawals are tax-free, so leaving that account to compound the longest captures the most value from its tax treatment, according to the framework laid out in IRS Publication 590-B.

That default is a reasonable starting point, not a rule to follow blindly. Two adjustments produce better outcomes for most retirees.

Fill low brackets deliberately in early retirement. The years between retiring and your RMD age are often the lowest-income years of your life. Drawing some traditional IRA money during that window, even beyond what you need to spend, and paying tax on it at a low bracket, can reduce the size of the RMDs that would otherwise force larger withdrawals into higher brackets later.
Watch Medicare premium thresholds. Higher-income retirees pay an Income-Related Monthly Adjustment Amount, or IRMAA, on Medicare Part B and Part D premiums, based on modified adjusted gross income from two years earlier. A large withdrawal or Roth conversion in one year can trigger a higher IRMAA bracket two years later, so sequencing decisions should account for that lag, not just the current year’s tax bracket.

How Precious Metals Are Taxed Inside Versus Outside an IRA

The tax treatment of gold and silver depends entirely on where the metal sits, and this is where the collectibles rules described earlier stop applying. Physical bullion and coins that meet IRS purity requirements and are held in a self-directed IRA through an approved custodian are specifically exempted from collectible treatment under IRC Section 408(m)(3). That exemption is what makes a gold IRA legal in the first place. It’s also why the metal must be held by the custodian and never taken into personal possession.

Inside a traditional gold IRA, distributions are taxed as ordinary income, the same as a distribution of cash or stock from any other traditional IRA, per IRS Publication 590-B. The collectibles cap of 28% doesn’t apply here at all, because the distribution is a retirement account withdrawal, not a sale of a collectible. Inside a Roth gold IRA, qualified distributions are tax-free, following the same rules as any other Roth account.

Outside an IRA, in a taxable account, physical metal is taxed as a collectible under IRC Section 408(m), with long-term gains capped at 28% as described above. This is the single most common point of confusion for investors researching a gold IRA rollover: the collectibles rate is a taxable-account rule, and it does not follow the metal once it’s inside a properly custodied IRA.

One practical wrinkle applies at RMD time for a metals IRA. Because the account holds physical bullion rather than cash, the custodian typically offers two options to satisfy an RMD: liquidate a portion of the metal to cash, or take an in-kind distribution of the physical metal itself, which is then valued at fair market value for RMD and tax-reporting purposes. Either option satisfies the RMD requirement, but they have different practical consequences worth discussing with your custodian and tax preparer before the distribution deadline.

Coordinating the Five Levers Into One Strategy

None of these levers work in isolation as well as they work together. A Roth conversion decided without checking its effect on your IRMAA bracket two years out is an incomplete decision. An RMD taken without considering whether a QCD could offset it is leaving a deduction on the table. A withdrawal sequence built around the default taxable-then-deferred-then-Roth order, without adjusting for the low-income years before RMDs begin, misses the single biggest bracket-management opportunity most retirees get.

The starting point for coordinating these decisions is an honest projection of your income by year, factoring in Social Security timing, pension income if applicable, and the RMD schedule from the table above. From there, Roth conversion amounts, harvest timing, and withdrawal order can be set year by year rather than decided once and left alone. If you’re still assembling the account structure this strategy will run on, the self-directed IRA and gold IRA rollover guides cover how to set up the accounts these decisions apply to, and the retirement calculator can help model how account balances shift under different withdrawal assumptions.

Retirement Tax Strategy FAQ

What’s the difference between tax-deferred and tax-free retirement accounts?

A tax-deferred account, like a traditional IRA or 401(k), lets contributions grow without annual tax, but withdrawals in retirement are taxed as ordinary income. A tax-free account, like a Roth IRA, is funded with already-taxed dollars, and qualified withdrawals owe no tax at all, per IRS Publication 590-A.

Can I do a Roth conversion after I’ve already started taking RMDs?

Yes, but the RMD for the current year must be satisfied first, and the RMD amount itself cannot be converted. Converting additional balance on top of the RMD is allowed and can still make sense if it fills an otherwise low bracket, according to IRS Publication 590-B.

Does tax-loss harvesting work inside a gold IRA?

No. Losses inside any IRA, including a gold IRA, are not deductible because the account doesn’t recognize gains or losses as they occur. Tax-loss harvesting only applies to taxable brokerage accounts.

What happens if I miss an RMD deadline?

The IRS applies an excise tax on the shortfall, 25% under current law, reduced to 10% if you correct the missed distribution within two years, per IRS Publication 590-B. Filing Form 5329 with a reasonable-cause explanation can sometimes result in the penalty being waived entirely.

Is the 28% collectibles rate the same as the capital gains rate on stocks?

No. Stocks and funds held long-term are taxed at 0%, 15%, or 20% depending on income. Physical metals held in a taxable account are taxed as collectibles under IRC Section 408(m), capped at 28%, which is a different and generally higher rate than the standard long-term capital gains brackets.

Do required minimum distributions apply to Roth 401(k) accounts?

Not anymore. SECURE 2.0 eliminated lifetime RMDs for Roth 401(k) and Roth 403(b) accounts starting in 2024, aligning their treatment with Roth IRAs, which have never had a lifetime RMD requirement.
