A GS-14 with 15 years of service and $690,000 in combined retirement accounts looks like they're doing everything right. And in many ways they are — consistent TSP contributions, a pension building in the background, a spouse with their own 401k. The household is on a solid trajectory.
But there's a problem quietly compounding underground, and most federal employees at this level don't see it until they're within five years of retirement.
That $690,000 in pre-tax retirement accounts is going to be $1.8–2.2 million by retirement age. At age 73, the IRS will require mandatory distributions from every dollar of it — whether this household needs the income or not. Those Required Minimum Distributions, stacked on top of a $95,000 pension and Social Security, could push them permanently into the 32% bracket. For the rest of their lives.
The solution isn't panic. It's a systematic, multi-engine income strategy — started now, while there are still 15 years of compounding runway and a relatively low tax bracket to work with. And the first engine to build is the one most people overlook entirely.
"A $690,000 pre-tax TSP balance at 52 becomes a $2 million RMD time bomb at 67 — unless you start building the antidote now."
Before dividends, before Roth conversions, before any of it — every serious income portfolio needs a safe, liquid, weekly foundation. Here's how to build it from scratch.
For our GS-14 profile, the T-Bill ladder serves a very specific purpose: it is the short-term reserve engine. Not the growth engine. Not the primary income engine. The foundation — the place where capital sits safely, earns predictable weekly income, stays liquid enough to fund annual Roth IRA contributions, handle emergencies, and redeploy when opportunities arise.
The structure is simple. Buy four 28-day Treasury Bills, each maturing one week apart. When the first matures, reinvest at the current rate. Repeat every week, indefinitely. The result is a rolling income machine currently yielding approximately 3.7–3.8% annually — exempt from state income tax in all 50 states — with zero credit risk and full principal returned on a rolling four-week cycle.
"The T-Bill ladder isn't exciting. That's the point. It is the financial equivalent of a solid foundation — you build everything else on top of it."
For a federal employee specifically, the T-Bill ladder plays especially well because of what they already have: a FERS pension providing a guaranteed income floor at retirement. That guarantee means the investment portfolio doesn't need to be defensive — it can reach for yield. But that only works when the short-term reserves are locked down first. The T-Bill ladder is that lock.
The state tax exemption is worth dwelling on. A household in Virginia, Maryland, or California — states where many federal employees live — is paying meaningful state income tax on money market fund distributions and high-yield savings interest. T-Bill interest is categorically exempt from those taxes. On $50,000 in a 5.75% state, that exemption is worth roughly $250–300 per year at current yields — just from holding the right instrument, with no additional risk.
Determine how much goes into the ladder. Divide by four — that's each rung. For our GS-14 profile starting conservatively, $20,000–40,000 total is a reasonable initial ladder. Purchase through TreasuryDirect.gov (free, direct from the government) or your brokerage account (minor commission, more convenient to manage).
Week 1: buy your first T-Bill maturing in 28 days. Week 2: buy the second. Continue for four weeks until every rung is filled. After the initial setup month, you will have one T-Bill maturing every single week going forward.
At TreasuryDirect, set reinvestment for up to two years. At a brokerage, configure standing reinvestment orders. Each maturing rung rolls principal and interest at the current market rate automatically — no manual action required week to week.
The 4-week ladder is designed to be left alone. Check yields quarterly. If the Fed cuts rates aggressively, consider extending some rungs to 13-week or 26-week T-Bills to lock in higher rates for longer. Otherwise, let it run.
As cash flow increases from TSP contributions freeing up take-home pay, dividend income from the brokerage, or other sources — add capital to the ladder. The GS-14 profile's long-term goal is building this into a $300,000–400,000 ladder by retirement, generating $11,000–15,000 per year in safe income on top of everything else.
Money market funds hold a mix of short-term instruments including corporate paper — their distributions are fully taxable at both federal and state levels. T-Bills are state-exempt. For a GS-14 household in Virginia paying 5.75% state income tax, that exemption effectively adds roughly 0.25–0.40% to the after-tax yield — every year, on every dollar, with identical safety. Over 15 years on a $50,000 ladder that's a meaningful advantage from a single structural choice.
The T-Bill ladder is Engine One. But the GS-14 profile needs a full four-engine system running simultaneously — each one playing a distinct role, each one funding or reinforcing the others.
| Engine | What It Holds | Est. Yield | Frequency | Tax Treatment |
|---|---|---|---|---|
| 1 · Safe Reserve | T-Bill Ladder | ~3.72% | Weekly | Federal only · state exempt |
| 2 · Dividend Core | SCHD · VYM | 3.1–3.8% | Quarterly | Qualified dividends |
| 3 · Income Booster | JEPI · JEPQ · O | 5.6–9.1% | Monthly | Ordinary income* |
| 4 · Roth IRA (Both) | SCHD · JEPI · JEPQ · VYM | Same holdings | Monthly/Qtly | Tax free forever · no RMDs |
* JEPI and JEPQ distributions are largely taxed as ordinary income in a taxable brokerage account. This is why they are priority candidates for the Roth IRA — inside a Roth, that ordinary income treatment is completely irrelevant. Tax-free is tax-free regardless of distribution type.
At a combined household income exceeding the direct Roth IRA contribution limit, this couple cannot contribute to a Roth IRA the traditional way. But they can use the backdoor Roth method — contributing to a non-deductible traditional IRA and immediately converting it to Roth. At $8,000 per person per year (the 50+ catch-up limit), that's $16,000 annually going into accounts that grow and withdraw completely tax-free, with no Required Minimum Distributions ever. The full backdoor Roth walkthrough is in Issue 003.
If the GS-14 profile executes this system consistently over 15 years — maxing TSP, building the brokerage dividend engine, funding $16,000/year in backdoor Roth contributions, and growing the T-Bill ladder — here is what the retirement income picture looks like.
That $143,000 estimate does not include any TSP withdrawals. The TSP at that point — potentially $1.8–2.2 million — sits as a strategic conversion target. From age 67 to 73, the gap between retirement and Required Minimum Distributions is a six-year window to convert chunks of the TSP to Roth at controlled tax rates. The Roth dividend income helps fund the conversion tax bills. This is the strategy Issue 005 covers in full detail.
The GS-14 profile is building toward what financial planners call three-bucket tax diversification: taxable income (pension, SS, T-Bill interest), tax-deferred (TSP — converted strategically), and tax-free (Roth IRA dividends). Most federal employees retire with everything in bucket one and two. The third bucket — built methodically through 15 years of backdoor Roth contributions — is what separates a good retirement from a great one.
