For a single filer between age 60 and the first required minimum distribution year, the federal ordinary income tax schedule at IRC Section 1 turns each remaining pre-RMD calendar year into a sizing fulcrum.
The marginal rate on your next dollar of taxable income sets the federal cost of every major decision. That rate applies whether you are sizing a partial Roth conversion, a partial 403(b) distribution, or a partial traditional-to-gold-IRA transfer under IRC Section 408(m).
The 2026 single-filer brackets are inflation-adjusted from the prior year under IRC Section 1(f). The post-TCJA rate schedule was carried forward by the One Big Beautiful Bill Act of 2025 (Public Law 119-21). The calendar-year 2026 dollar thresholds were released in Revenue Procedure 2025-32.
The first step in sizing a conversion is projecting baseline taxable income. That means summing pension payments, any 403(b) or traditional IRA distributions already on the calendar, and qualified dividends taxed as ordinary income when held outside a preferential account.
Also include projected Social Security if benefits have already started. Then subtract the 2026 standard deduction for single filers and the additional age-65 amount allowed under IRC Section 63(f).
Element II is the bracket-room calculation: the difference between projected taxable income and the upper threshold of the marginal bracket the filer currently sits in. Element III is the conversion size that uses some, but not all, of that room with a buffer below the next cliff.
A single filer in Tennessee pays no state income tax on wages, pensions, or IRA distributions. That makes the federal bracket schedule the only schedule to plan against. For a single filer with an $89,000 traditional 403(b) balance and a modest pension, the federal bracket geometry is the entire conversion-sizing problem.

Before you finalize the year-end conversion calendar
The 2026 single-filer bracket question is a tax-sequencing question, not a dealer question. Most of the planning sits with a CPA or fiduciary planner.
If any portion of the converted balance will fund a self-directed metals sleeve in the same calendar year, the dealer choice is the one part still reversible before signing. That means you can change the dealer before any metals invoice or wire instruction goes out.

The 2026 single-filer brackets at a glance
The bracket schedule is set annually by the IRS through the inflation-adjustment process at IRC Section 1(f), using the Chained CPI for All Urban Consumers (C-CPI-U) as the index. The October 2025 release in Revenue Procedure 2025-32 set the 2026 dollar thresholds.
The bracket count (seven), the rate values (10, 12, 22, 24, 32, 35, 37 percent), and the bracket structure are statutory under IRC Section 1. They were carried forward by the One Big Beautiful Bill Act of 2025 (Public Law 119-21), which made the post-TCJA rate schedule permanent. The TCJA sunset scheduled for the end of 2025 was eliminated by OBBBA.

Precious metals IRA early-withdrawal penalty estimator
Taking money out of a precious metals IRA before age 59 and a half triggers a 10% federal additional tax on top of ordinary income tax. State add-on taxes vary; check your state. The federal penalty is estimated below.
Estimate only, not tax advice. The 10% federal additional tax applies to early distributions before age 59 and a half; specific exceptions exist. Your state may add its own tax, and ordinary income tax applies separately. Source: IRS Publication 590-B. Consult a tax advisor.

The structural disadvantage of the single-filer schedule, compared with married-filing-jointly, is bracket width: each single-filer bracket sits at roughly half the dollar width of the equivalent MFJ bracket. The 22 percent bracket for single filers spans about $55,300 of taxable income ($50,400 to $105,700), where the same 22 percent bracket for MFJ filers spans about $110,600.
The 24 percent bracket for single filers spans about $96,075 ($105,700 to $201,775), where the same 24 percent bracket for MFJ filers spans about $192,150. The room calculation, and therefore the conversion size that fits inside the current bracket, is exactly half the MFJ equivalent.
A single filer planning a partial Roth conversion or a partial 403(b)-to-gold-IRA move has less calendar-year capacity than a couple, all else equal.
The 2026 standard deduction for a single filer is published in the same Revenue Procedure. Section 63(c)(2) sets the baseline single-filer amount, and Section 63(f)(1) adds the additional standard-deduction amount for a filer aged 65 or older. The IRS publishes the combined dollar values in the annual Revenue Procedure.
For a filer turning 65 in the calendar year, the additional amount applies in that year per the IRS interpretation in Publication 501. The deduction is subtracted from adjusted gross income to compute taxable income, and the bracket schedule applies to taxable income, not to AGI.
Why bracket geometry matters on any 403(b)-to-gold-IRA path
A trustee-to-trustee transfer from a traditional 403(b) account to a self-directed traditional IRA holding IRS-approved metals under IRC Section 408(m) is a non-taxable rollover.
The transfer itself does not create taxable income, provided the metals are held by an IRS-qualified custodian on the IRA owner’s behalf (not in personal possession). The metals must also meet the purity standards at Section 408(m)(3).
The reporting form for the rollover is Form 5498 from the receiving custodian, and the distributing 403(b) administrator issues Form 1099-R coded G (direct rollover, not taxable).
The bracket question enters at a different step. If any portion of the 403(b) balance is converted (not rolled) from traditional pre-tax to Roth, that conversion under IRC Section 408A(d)(3) is fully taxable in the year of the conversion as ordinary income.
The same applies to any direct distribution under IRC Section 402(a) that is not rolled over within 60 days. The taxable amount stacks on top of pension, Social Security (subject to IRC Section 86 inclusion rules), and other ordinary income for the year, and the result lands somewhere in the seven-bracket schedule above.
The conversion size determines which marginal rate the converted amount actually pays.
Consider a single filer with $89,000 in a traditional 403(b) and a modest pension of $32,000 per year. If no Social Security has started and the filer qualifies for the standard deduction plus the age-65 additional amount, baseline taxable income before any conversion is the pension net of the deduction.
That places the filer near the bottom of the 12 percent bracket.
The room from there to the top of the 12 percent bracket ($50,400 of taxable income) is the first natural conversion ceiling. The room from there to the top of the 22 percent bracket ($105,700) is the larger conversion ceiling, paying 22 percent federal on the portion of the conversion that sits inside that band.
For a 60- to 65-year-old planning to delay Social Security to age 70, the pre-RMD window is the cleanest opportunity to migrate 403(b) balances into a Roth wrapper at known marginal rates. That delay is the actuarially favored decision for a single Tennessee teacher with longevity in the family.
The five-step bracket-aware conversion sizing sequence
The November-or-December planning sequence for any partial Roth conversion (or partial pre-tax-to-gold-IRA path that involves a Roth segment) follows five steps. Each step is mechanical once the prior step is complete, and each step has a documented source.

Step 1, inventory baseline taxable income. Sum the calendar-year pension payments, any 403(b) distributions already taken or scheduled, and qualified dividends and taxable interest from non-retirement accounts. Add projected Social Security (with the Section 86 provisional-income computation applied to determine the taxable portion), plus any other items reportable on the 1040.
The result is the baseline AGI before deductions.
Where the filer has not yet started Social Security, the projection is whatever the SSA my Social Security portal shows for the planned claim date, prorated to the months of receipt in the calendar year.
Step 2, subtract the 2026 standard deduction and age-65 additional amount. Take the single-filer standard deduction value published in Revenue Procedure 2025-32, and add the Section 63(f)(1) additional amount if the filer is 65 or older at the end of the tax year. The result is baseline taxable income. This is the input to the bracket schedule, not AGI.
Step 3, pull the Rev Proc 2025-32 bracket schedule and compute the room. Identify which bracket baseline taxable income falls into. Compute the dollar room from baseline to the next bracket edge.
For a single filer with baseline taxable income of $40,000 (inside the 12 percent bracket), the room to the top of the 12 percent bracket is $10,400 ($50,400 minus $40,000). The room to the top of the 22 percent bracket is $65,700 ($105,700 minus $40,000).
For a single filer with baseline of $70,000, inside the 22 percent bracket, the room to the top of that bracket is $35,700. The room to the top of the 24 percent bracket is $131,775.
Step 4, pick a conversion size that leaves a buffer. A 5 to 10 percent buffer below the next bracket cliff handles two real-world risks. The first is pension or Social Security inflation adjustments that arrive after the year ends but apply to the planning year. The second is unexpected qualified-dividend or capital-gain distributions from mutual funds held in taxable accounts that land in December.
A 5 percent buffer on a $35,700 room means a target conversion of $33,915, leaving $1,785 of bracket cushion. A 10 percent buffer means a target of $32,130. The conservative choice (closer to 10 percent) is the standard for retired single filers with multiple variable income streams.
Step 5, execute the trustee-to-trustee transfer and report. The 403(b) plan administrator and the receiving IRA custodian coordinate the direct transfer. The 1099-R from the 403(b) plan is coded 2 (early distribution with exception) or 7 (normal), depending on age. It is coded G if the route is a direct rollover to a traditional IRA before a Roth conversion.
The Roth conversion is then reported on Form 8606 filed with the 1040 for the conversion year. If the destination IRA holds metals under Section 408(m), the receiving custodian reports the metals holdings on Form 5498 in the following January.
Common single-filer mistakes near bracket cliffs
Mistake one, sizing the conversion against AGI instead of taxable income. The bracket schedule applies to taxable income (line 15 of the 1040), not AGI (line 11). A conversion that looks safe at AGI may push taxable income over the bracket edge. Always subtract the standard deduction (and age-65 additional amount, if applicable) before computing the room.
Mistake two, ignoring the Social Security provisional-income stacking effect. Under IRC Section 86, a single filer’s provisional income (AGI plus tax-exempt interest plus 50 percent of Social Security) determines how much of the Social Security benefit is included in taxable income.
A Roth conversion increases provisional income, which can push more of the Social Security benefit into taxability (up to 85 percent inclusion). The marginal rate on the converted dollars is then effectively higher than the bracket rate alone suggests.
The OPRS guide on the IRMAA bracket schedule for 2026 Roth conversion planning walks through how the same conversion size also affects the two-year Medicare premium lookback, which is a separate cliff.
Mistake three, executing the conversion in December without recomputing baseline. Pension administrators sometimes issue catch-up payments or correction adjustments in December that change baseline taxable income after the November planning was done. Recompute baseline against the most recent 1099 estimates before authorizing the trustee-to-trustee transfer, and consider executing in early December with explicit buffer rather than late December with no margin.
Mistake four, treating a partial 403(b) distribution as a Roth conversion. A direct distribution from a 403(b) is taxable as ordinary income and may also be subject to the 10 percent early-distribution additional tax under IRC Section 72(t) if taken before age 59 and a half.
A Roth conversion is also taxable as ordinary income, but the resulting balance grows tax-free in the Roth wrapper. The two are not interchangeable for retirement-income planning, even though both fill bracket room similarly in the conversion year.
Mistake five, not separating ordinary income from preferentially taxed capital gains. Long-term capital gains and qualified dividends are taxed under IRC Section 1(h) at 0, 15, or 20 percent rates with a separate threshold schedule. They stack on top of ordinary income for purposes of determining which long-term capital gains rate applies, but they do not consume ordinary-income bracket room.
A single filer with $60,000 of ordinary income and $20,000 of qualified dividends has $60,000 of taxable ordinary income, not $80,000, for the Section 1 bracket schedule. The Section 1(h) schedule for the qualified dividends is a separate calculation.
OBBBA permanence and what could still change after 2026
The post-TCJA seven-bracket rate schedule (10, 12, 22, 24, 32, 35, 37 percent) had been scheduled to sunset at the end of 2025. Under that sunset, brackets would have reverted to pre-TCJA values: 15, 28, 31, 36, and 39.6 percent. The One Big Beautiful Bill Act of 2025 (Public Law 119-21) made the post-TCJA rate schedule permanent.
The bracket structure for 2026 and later years is therefore the same seven-bracket schedule, with dollar thresholds adjusted annually for inflation under Section 1(f).
The 2027 thresholds will be published by the IRS in the October 2026 Revenue Procedure. The dollar values will increase by approximately the C-CPI-U change from August 2024 through August 2026, consistent with the indexation reference period defined in Section 1(f)(3).
What the post-OBBBA permanence does not eliminate is future legislative change. Future Congresses can change the bracket count, the rate values, or the threshold structure at any time.
The current planning assumption is that the seven-bracket schedule persists. That is the working baseline for 2026 and 2027 conversions. A multi-year ladder running into 2028 or 2029 should be re-checked against any tax legislation that passes in those years.
For single filers in the 60-to-65 window planning a five-year conversion ladder, lock in the larger conversions in 2026 and 2027. The bracket schedule is known and stable for those years. Size the later-year conversions more conservatively to leave room for legislative volatility.
Sub-Augusta-threshold pathways for the $89,000 starting balance
For a single filer with a starting 403(b) balance near $89,000, the working partner thresholds matter. Augusta Precious Metals’ industry-reported minimum sits around $50,000 for self-directed gold IRA accounts (per the partner’s published account-opening materials at the time of writing), which means the entire $89,000 balance is above their working floor.
A partial conversion that leaves the remaining balance in the traditional 403(b) for a future-year conversion is still feasible. For filers whose 403(b) balance is meaningfully below $50,000, our guide on whether a gold IRA makes sense for balances under $100,000 walks through which partners accept lower minimums. It also explains how the per-account cost structure changes the break-even calculation.
For an $89,000 balance specifically, a two-year ladder works well. Sizing roughly $40,000 in 2026 and the remainder in 2027 keeps each calendar year inside a single marginal bracket for most baseline-income scenarios. A one-year full conversion would push a single filer with even a modest pension up two brackets in a single year.
The two-year ladder is the standard approach for single filers in this balance range. Whether the destination is a Roth wrapper with a metals sleeve or a traditional IRA with a metals sleeve is a separate question. The bracket arithmetic is the same in either case for any portion that is converted, not rolled.
Before authorizing any 2026 partial Roth conversion or partial 403(b)-to-gold-IRA path, run the five-step sequence with a tax professional. Document the baseline taxable income inputs and pick a conversion size that leaves a 5 to 10 percent buffer below the next bracket cliff.
The federal bracket schedule in Rev Proc 2025-32 is the constraint. The metals destination and the dealer choice are separable downstream questions. The dealer choice is the one a single filer can still reverse before signing a metals invoice.
