The 4-Year Tax Opportunity
(2025–2028) Explained
Right now — for the next four years — federal employees and retirees are living through one of the most favorable tax windows in a generation. Here is exactly what it means, what is at stake, and what to do about it.
Every day that passes without a Roth conversion, strategic gift, or income recognition is a day of tax opportunity you cannot recover. Use this guide to move with urgency and purpose.
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.
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.
| Tax Feature | Current (2025–2028) | Historical Context / Future Risk | Action Opportunity |
|---|---|---|---|
| Top Marginal Rate | 37% | Was 39.6% pre-2018; could return in future legislation | Convert/recognize income at today's rate |
| 22% Bracket Ceiling (MFJ) | Up to $206,700 | If rates rise, this ceiling drops — more income in higher brackets | Wide Roth conversion opportunity in this bracket |
| Standard Deduction (MFJ) | $30,700 (+ $2,600 if both 65+) | Lower deductions historically reduce tax shelter for retirees | Higher tax-free income base for pension + SS |
| Estate/Gift Exemption (per person) | $13.99 million | Pre-2018 level was ~$5.5M; could revert or be reduced by legislation | Accelerate large gifts and trust strategies NOW |
| Long-Term Capital Gains Rates | 0%/15%/20% | Could increase; additional 3.8% NIIT applies above $200K/$250K | Harvest gains at 0% or 15% while bracket allows |
| Roth TSP In-Plan Conversions | Available since Jan 2026 | New option — allows conversion inside TSP without IRA rollover | Convert during low-income retirement years |
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
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.
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.
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.
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.
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 2028Strategic 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, 2028Capital 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 2025–2028Income 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 202804 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.

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.

- 🟢 $13.99 million exemption per person
- 🟢 $27.98 million per married couple combined

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.
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
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.
