For many senior military officers, the first five years after service are the most important tax planning window of their lifetime.
This period often determines:
- Whether Roth conversion opportunities exist
- How much lifetime tax drag accumulates
- Whether pension income permanently crowds out flexibility
- How second-career income layers into federal brackets
- Whether state tax relocation actually produces savings
The risk is not a single bad investment decision.
The risk is structural tax compression.
What Is Tax Compression?
Tax compression occurs when multiple income streams begin simultaneously and push a retiree into higher marginal brackets — eliminating flexibility before it can be used.
For senior officers, compression often results from:
- Immediate military pension income (taxable as ordinary income)
- Civilian or consulting income
- TSP distributions
- Capital gains
- Required Minimum Distributions later in life
Military retired pay is fully taxable as ordinary income at the federal level. (IRS Publication 525) Without intentional sequencing, this layering can permanently increase lifetime tax exposure.
Why the First Five Years Matter
Before age 73, Required Minimum Distributions (RMDs) from traditional retirement accounts are not mandatory. (SECURE 2.0 Act; IRC §401(a)(9)) This creates a limited window where income can be strategically managed.
However, once pension begins, second-career income ramps, and investment income grows, the opportunity for strategic Roth conversion or bracket management may narrow significantly. For many officers, once second-career income is fully established, the Roth conversion window effectively closes.
Structure first. Optimization second.
The Pension Effect
Military retired pay begins immediately upon retirement (active duty) or at eligible age (reserve component). It is taxable at the federal level, subject to state taxation depending on residency, and adjusted annually for COLA. (DFAS; IRS Publication 525)
That guaranteed income floor is powerful. It is also bracket-filling. Every dollar of pension income consumes lower marginal tax space — reducing the room available for tax-efficient withdrawals, conversions, or other income management strategies.
Roth Conversions: Timing Matters
Roth conversions are taxed as ordinary income in the year converted. (IRS Publication 590-B) If performed before second-career income accelerates, during lower-income transition years, and prior to RMD age, they may reduce lifetime tax burden and future RMD exposure.
If delayed until full civilian income is layered in, conversions may become inefficient or entirely unavailable. The sequencing window is finite — and most officers underestimate how quickly it closes.
State Tax Relocation: Often Misunderstood
Some states fully exempt military retired pay. Others partially exempt it. Some tax it fully. State taxation varies — see individual state revenue departments for current exemption status.
Relocation decisions should consider pension taxation, civilian income taxation, property tax, estate tax laws, and total cost of living. Relocation for tax reasons alone often produces less savings than expected when modeled comprehensively. The relevant analysis is total post-tax income, not pension exemption status alone.
The TSP Factor
Traditional TSP balances are tax-deferred. Roth TSP balances are tax-free if qualified. (IRS Publication 590-B; Thrift Savings Plan regulations)
Without early planning, large traditional balances may generate substantial RMDs beginning at age 73, which can trigger Medicare Part B and D premium surcharges (IRMAA). (Social Security Administration; Medicare IRMAA guidelines) Tax compression compounds in later retirement if not addressed early.
Where This Fits in the ILS Decision Sequencing System™
Tax compression planning falls under Step 4 of the ILS framework — but it cannot be executed without completing the earlier steps first. Investment allocation is optimized only after tax sequencing is defined.

The Structural Reality
For senior officers: pension fills lower brackets, civilian income compresses remaining space, large TSP balances create future RMD risk, and delay eliminates optionality.
The first five years after service are often the most powerful tax planning opportunity available. After that window closes, flexibility declines — not because of bad investments, but because income structure has become fixed.
Frequently Asked Questions
-
Is military retired pay taxable?
Yes. Military retired pay is taxable as ordinary income at the federal level. (IRS Publication 525) State taxation depends on residency — some states provide full or partial exemptions.
-
What is the current RMD age?
Under current federal law (SECURE 2.0), Required Minimum Distributions begin at age 73 for most retirees. (IRC §401(a)(9))
-
What is tax compression in retirement?
Tax compression occurs when multiple income sources — pension, civilian income, retirement withdrawals — push income into higher marginal tax brackets simultaneously, reducing the flexibility to manage tax exposure going forward.
-
When is the best time to consider Roth conversions?
Often during lower-income transition years — after military retirement, before full second-career income ramps, and prior to RMD age. Conversions are taxed as ordinary income in the year performed. (IRS Publication 590-B) The window is finite and individual modeling is required.
-
Does VA disability compensation affect tax brackets?
VA disability compensation is generally not taxable at the federal level. (IRS Publication 525) However, it does not reduce the taxable nature of military retired pay for bracket planning purposes unless it is below the 50% rating threshold for concurrent receipt eligibility.
-
Should I relocate to reduce state taxes?
Possibly — but relocation should be modeled holistically. Some states exempt military retired pay; others partially or fully tax it. Total tax burden must be evaluated alongside cost of living, property taxes, and estate laws. The savings are often smaller than expected when modeled comprehensively.
-
Can large TSP balances create future tax challenges?
Yes. Large traditional TSP balances can generate significant Required Minimum Distributions at age 73, potentially pushing income into higher federal tax brackets and triggering Medicare Part B and D premium surcharges (IRMAA). (Social Security Administration) Early sequencing of tax buckets can reduce this risk.
-
Is tax planning more important than investment returns?
Tax sequencing can have permanent lifetime effects that investment returns cannot recover. A one percent improvement in after-tax efficiency, compounded over 25 years, often exceeds the benefit of a comparable improvement in gross returns. Structure determines long-term efficiency — and tax structure should be addressed before portfolio optimization.
