Every so often, the tax code creates a window — a period when the rules are aligned in a way that favors deliberate financial action. The years from 2025 through 2028 represent one of the most clearly defined such windows in recent memory. Relatively low marginal rates, an historically high standard deduction, a generous estate and gift tax exemption, and the ability to shift income between tax years and account types have all converged simultaneously.

For federal employees with large Traditional TSP balances, a FERS pension, and assets that will pass to heirs, this window is not theoretical — it is an active planning mandate. This guide from Warrior Retirement explains every component of the 4-year opportunity and the exact strategies that federal employees and retirees should be executing right now.

⚡ Quick Answer — What Is the 4-Year Tax Opportunity?

The 4-year tax opportunity refers to the 2025–2028 period of relatively favorable federal tax conditions — including the current income tax brackets, an elevated standard deduction, and a high estate and gift tax exemption — that may change as Congress revisits tax policy. Whether future changes increase tax rates, reduce deductions, or lower estate exemptions, federal retirees who take action now lock in today's favorable rules for decades of future benefit. The three core strategies: Roth conversions, strategic gift giving, and income recognition — all executed while your tax rate is at or near its historic low point.

01 What Makes 2025–2028 a Tax Planning Window?

The tax environment in 2025–2028 is defined by several specific, measurable advantages compared to historical norms and possible future changes. Understanding each component lets you prioritize which strategies matter most for your situation.

🔥
This Window Is Unusual — And Time-Limited

From 2025 to 2028, the combination of lower rates AND a higher estate exemption AND an elevated standard deduction is historically uncommon. These three features rarely align simultaneously. Federal retirees who delay have no guarantee the same opportunity will exist in 2029, 2030, or 2031. Act in the window, not after it closes.

02 The 4-Year Window — Year by Year

2025 — Completed

Foundation Year — Assessment & First Conversions

Roth conversions using 2025 income picture. Estate plan review begun. First large gifts under the annual exclusion executed. Baseline financial picture established for the window ahead.

2026 — We Are Here

The Prime Conversion Year — TSP Roth In-Plan Now Live

TSP Roth in-plan conversions launched January 28, 2026 — the most significant new tool for federal employees. Maximize Roth conversions up to the top of your current bracket. Execute large gifts using the $13.99M exemption if applicable. IRMAA management critical for two-year lookback planning.

2027 — Mid-Window

Accelerate — Trusts, Gifting, Continued Conversions

Second year of systematic Roth conversions. Irrevocable trusts and ILIT strategies should be in force by now. Capital gains harvesting at favorable rates. Review Social Security claiming strategy if not yet claimed.

2028 — Final Year

Last Call — Final Conversions, Gifts, & Income Recognition

The final calendar year of the defined window. Any income recognition, Roth conversion, or gift strategy that was not executed must be completed by December 31, 2028. Policy uncertainty increases heading into 2029.

2029+ — Unknown

New Rules — Whatever Congress Decides

Congressional action (or inaction) determines what changes. Tax rates, brackets, deductions, and exemptions are all subject to revision. The strategies executed 2025–2028 are locked in regardless of what 2029 brings — gifts made, Roth conversions done, trusts funded are permanent.

03 The Three Core Strategies for 2025–2028

🔄

Roth Conversions — The Primary Play

Convert Traditional TSP and IRA balances to Roth at today's rates. Every dollar converted is taxed now — at 22% or lower — and grows completely tax-free forever. Future RMDs from this balance: $0. Future tax: $0.

⏰ Execute annually through 2028
🎁

Strategic Gifting — Use the High Exemption

The $13.99M estate exemption per person is historically high. Gifts made under today's exemption are permanently protected — even if the exemption drops in future years. Large transfers to heirs, trusts, or 529s are most valuable while this exemption stands.

⏰ Trusts must be funded by Dec 31, 2028
📈

Capital Gains Harvesting — Lock In 0–15% Rate

Long-term capital gains are taxed at 0% for married couples with taxable income under $96,950. Realizing gains at 0% now — harvesting appreciated positions, resetting cost basis — is a powerful and irreversible benefit while the bracket window is open.

⏰ Available each year 2025–2028
🏛️

Income Recognition — Pull Income Into Favorable Years

If you have income you can control the timing of — deferred comp, consulting income, rental property, TSP withdrawals — recognize it while in a favorable bracket. Spreading income across 4 years at 22% is better than cramming it into 1–2 years at higher future rates.

⏰ Time year-by-year through 2028

04 Roth Conversions: The Math That Drives the Entire Window

Roth conversions are the single most impactful strategy available to most federal retirees during this window. The math is simple: if your tax rate is lower today than it will be when you take the money out, converting now saves money permanently. The question is not whether to convert — it is how much and in which years.

💡 Roth Conversion: How Much Can You Convert at Each Tax Rate? (MFJ, 2026)
12% bracket top
Up to $96,950 taxable income
$96,950 ceiling
12% tax
22% bracket top
Up to $206,700 taxable income
$206,700 ceiling
22% tax
24% bracket top
Up to $394,600 taxable income
$394,600 ceiling
24% tax

Strategy: Fill up to the top of your current bracket with conversions each year. A retired couple with a $60,000 combined pension can convert up to $116,950 of TSP to Roth at 22% before crossing the 24% threshold — spending $25,729 in tax to shift $116,950 permanently into Roth.

06 The Estate Exemption: Use It While It Stands

The current federal estate and gift tax exemption of $13.99 million per person ($27.98 million for a married couple) is the highest it has ever been in inflation-adjusted terms. Future legislation could reduce this amount. Gifts made under today's exemption are permanently protected — even if the exemption decreases later.

🟢 2025–2028 Estate Rules (Use Now)

  • 🟢 $13.99 million exemption per person
  • 🟢 $27.98 million per married couple combined
  • 🟢 Annual gift exclusion: $19,000 per recipient per donor (2026)
  • 🟢 Superfunding 529: $95,000 per beneficiary (5-year election)
  • 🟢 Direct tuition payments: unlimited (pays school directly)
  • 🟢 Gifts made now are protected even if exemption drops

⚠️ Potential Future Estate Environment

  • ⚠️ Exemption could be reduced by future legislation
  • ⚠️ Estates above any new lower threshold taxed at 40%
  • ⚠️ Fewer gifting and trust strategies available
  • ⚠️ Retroactive protection does not apply to future gifts
  • ⚠️ Irrevocable trusts not yet funded lose the protection
  • ⚠️ Higher effective tax on multi-generational wealth transfer

$195,000 converted to tax-free Roth + $190,000 in 529 gifts + $152,000 in annual exclusion gifts = $537,000 repositioned at favorable rates or removed from taxable estate. Tax cost: ~$43,000 in Roth conversion taxes — one of the highest-return planning investments available.

07 Capital Gains Harvesting: The 0% Bracket Is Bigger Than You Think

For married federal retirees with taxable income below $96,950, long-term capital gains are taxed at 0%. If your pension and TSP withdrawals leave you in the 12% bracket, you may be able to sell appreciated stock, mutual funds, or investment property and pay zero federal capital gains tax on the gain.

💡
The 0% Capital Gains Strategy — Reset Your Cost Basis for Free

If you own appreciated investments in a taxable brokerage account, selling and immediately repurchasing resets your cost basis to today's price — at 0% federal tax. This eliminates the embedded gain for future years when your income may be higher. A federal retiree couple with a $60,000 pension and $84,950 in capital gains space available (at the 0% threshold) could harvest those gains every year for 4 years — permanently eliminating taxable gains that would otherwise be taxed at 15%+ in higher-income years.

08 TSP Roth In-Plan Conversions — The New Tool That Changes Everything

🔄
Live Since January 28, 2026 — The Most Important New Federal Employee Tax Tool

Federal employees and retirees can now convert Traditional TSP balances to Roth TSP directly inside the Thrift Savings Plan — no rollover to an IRA required. Before this change, converting Traditional TSP to Roth required rolling funds out of TSP to a traditional IRA, then doing a Roth conversion — with loss of TSP's ultra-low expense ratios during the process. Now, conversions happen in-plan. Execute your 4-year window Roth conversion strategy entirely within TSP. Read our complete guide: TSP Roth In-Plan Conversions — Complete 2026 Guide.

09 Frequently Asked Questions

What exactly expires or changes after 2028?
The current favorable tax environment reflects tax policies enacted in recent years. Future Congressional action on tax reform, revenue needs, or expiring provisions could increase marginal rates, reduce deductions, or change the estate exemption. No specific expiration date is guaranteed for each provision — Congress can act at any time. The 4-year window acknowledges that the period 2025–2028 represents a defined planning opportunity while current rules are in effect, before the inevitable next round of tax legislation. The key insight: strategies executed now — Roth conversions, gifts, trust funding — lock in current rules regardless of future changes.
How much should I convert to Roth each year?
The optimal Roth conversion amount each year fills the gap between your current taxable income and the top of your target tax bracket — typically the top of the 22% bracket ($206,700 MFJ in 2026) for most FERS retirees. Do not convert into the 24% bracket unless your future rate would be significantly higher than 24%. Also watch IRMAA thresholds — a conversion that pushes your MAGI above $212,000 (married) triggers higher Medicare premiums two years later. Use the calculator above and consult a tax professional to find your exact annual conversion target.
Are Roth conversions reversible?
No — since 2018, Roth conversions cannot be reversed (recharacterized). The tax paid on a Roth conversion is permanent. This makes timing important: do not convert so aggressively that you push into a bracket you did not intend, or trigger IRMAA surcharges unexpectedly. Convert systematically and deliberately, within your planned bracket ceiling, rather than in large one-time amounts.
Does this apply to CSRS retirees as well?
Yes — CSRS retirees also benefit from the 4-year window for Roth conversions (from IRAs, since most CSRS employees have limited TSP access), capital gains harvesting, and estate planning. CSRS retirees with large IRA balances from personal savings or rollovers can execute the same Roth conversion strategy in the 2025–2028 window. The estate and gift tax strategies apply to all federal retirees regardless of whether they are FERS or CSRS.
