Comprehensive Tax Planning

It's not about what you earn in retirement — it's about what you keep. And the window to do something about it is shorter than you think.

I Kept Seeing This

For years, I thought the hard part of my job was helping people accumulate. Save more. Invest wisely. Grow the balance.

I was wrong.

The hard part — the part that determines whether retirement actually works — is the distribution phase. Getting the money back out. And almost nobody is thinking about it until it's too late.

I kept meeting people who'd saved $1 million, $1.5 million, sometimes more — all in traditional 401(k)s and IRAs. They felt wealthy. Then we'd run the numbers together, and I'd watch their face change. Because 25–35% of that balance? It belongs to the IRS. They hadn't saved $1.5 million. They'd saved $1.5 million in pre-tax dollars — and nobody had helped them think about the tax bill waiting on the other side.

$30K
Spreading a $300,000 Roth conversion over three years instead of doing it all at once can save $15,000–$30,000 in unnecessary taxes. A poorly timed conversion can also trigger $600+/month in Medicare IRMAA surcharges — a bill that shows up two years later.

Here's what made it worse: the window to do something about it — the years between retirement and age 73, when Required Minimum Distributions force money out — was ticking by. Every year they didn't convert, didn't plan, didn't act was a year of tax-planning opportunity they'd never get back.

That's when I made tax planning a non-negotiable in every retirement plan I build. Not a nice-to-have. Not an afterthought. A discipline — modeled before every withdrawal, every conversion, every trade.

Here's How I Think About It

Tax planning in retirement is really about three things: what order you pull money from, how much you convert from pre-tax to after-tax accounts each year, and how every dollar interacts with the rest of your financial picture.

Most people — and honestly, many advisors — treat withdrawals as a simple math problem. Need $80,000? Pull it from your IRA. But that $80,000 withdrawal triggers income tax, potentially pushes your Social Security benefits into taxation, and could bump your Medicare premiums for the next two years.

Tax Planning as a Chess Game

I think of it more like a chess game. Every move has ripple effects. My job is to model those effects before we act — not after. A withdrawal from a traditional IRA triggers income tax. That income might push Social Security into taxation. That combined income might trigger Medicare IRMAA surcharges two years from now. One move. Three consequences. That's why we model before every transaction.

The "C" in G.R.A.C.E. exists because I've seen first-hand how much money is left on the table when tax planning is reactive instead of proactive. We're talking about differences of hundreds of thousands of dollars over a 25–30 year retirement. Not from exotic strategies — from basic, disciplined, year-by-year tax bracket management.

The Tax Strategies That Make It Real

Roth Conversion Ladders

The years between retirement and age 73 (when RMDs begin) are the golden window for Roth conversions. During these years, your income often drops — you've left your paycheck behind, but Social Security and RMDs haven't started yet. That creates lower tax brackets and an opportunity to move money from your traditional IRA to a Roth IRA at a favorable tax rate.

The key is discipline and math. We "fill" a target bracket — typically the 24% or 32% bracket — each year without spilling into the next one. A family with a $300,000 traditional IRA balance might convert $100,000 per year over three years, staying within the 24% bracket each time, rather than converting all at once and spiking into the 35% bracket. The tax savings from that discipline alone can exceed $15,000–$30,000.

Once the money is in a Roth, it grows tax-free, is withdrawn tax-free, and is not subject to Required Minimum Distributions during your lifetime. The One Big Beautiful Bill Act made TCJA tax rates permanent, which provides planning certainty that didn't exist before.

Tax Bracket Management

You likely have money in three types of accounts: taxable (brokerage accounts), tax-deferred (traditional IRA/401k), and tax-free (Roth IRA). The order and combination in which you draw from these accounts has an enormous impact on your lifetime tax bill.

Drawing too heavily from tax-deferred accounts triggers income tax and can cascade into Social Security taxation and Medicare surcharges. Drawing from taxable accounts may trigger capital gains. A coordinated strategy blends withdrawals from all three sources to keep your effective tax rate as low as possible each year — not just this year, but across your full retirement.

RMD Strategy

Required Minimum Distributions begin at age 73 (or 75 for those born after 1960). Once they start, the IRS dictates the minimum you must withdraw from tax-deferred accounts each year — and you'll owe income tax on every dollar. For retirees with large traditional IRA balances, RMDs can push you into higher brackets, trigger Social Security taxation, and increase Medicare premiums.

The "two RMD trap" is especially costly: if you delay your first RMD until April 1 of the year after you turn 73, you'll take two distributions in the same calendar year, potentially spiking your tax bracket. Proactive Roth conversions before RMDs begin are one of the most effective tools for reducing this future burden. Roth IRAs have no lifetime RMDs.

Medicare IRMAA Avoidance

IRMAA — Income-Related Monthly Adjustment Amount — is Medicare's surcharge for higher earners. It's based on your modified adjusted gross income from two years prior. A large Roth conversion or unexpected capital gain in one year can trigger an additional $600 or more per month in Medicare premiums two years later.

Strategic planning spreads taxable events across years to avoid crossing IRMAA thresholds — or times larger conversions for years where IRMAA impact is minimized. This is one of the most commonly overlooked costs in retirement tax planning, and it's entirely avoidable with proper modeling.

Social Security Tax Optimization

Up to 85% of your Social Security benefits can become taxable income if your combined income exceeds certain thresholds. The thresholds are relatively low — $34,000 for single filers, $44,000 for married filing jointly. Drawing from Roth accounts instead of traditional IRAs can keep your combined income below these thresholds, effectively shielding your Social Security from federal income tax.

This is another reason why the Roth conversion window matters so much. The more you move to Roth before Social Security begins, the more control you have over whether — and how much — of your Social Security gets taxed.

The Surviving Spouse Tax Trap — The Urgency Most People Miss

This is the one that creates real urgency — and it's the one almost nobody talks about until it's too late.

When one spouse passes, the surviving spouse doesn't just lose a partner. They lose a tax bracket. They go from filing married filing jointly to filing single. The tax brackets compress. The standard deduction gets cut nearly in half. But here's what doesn't change: the RMDs, the Social Security income, the pension payments. All that income is now being taxed at single-filer rates.

22–24%
A couple paying an effective 15% federal rate today could see the surviving spouse paying 22–24% on the same income — simply because of the filing status change. Over a 10–15 year surviving-spouse period, that's tens of thousands of dollars in additional taxes.

Often, when I show a couple their projected tax impact from a Roth conversion or withdrawal reordering, the savings while they're both alive might look modest — maybe enough to say, "we'll get to it eventually." But when I add the surviving spouse column to the projection? When they see what happens to the tax bill after one of them is gone? That's when the conversation shifts from "we should probably do something" to "we need to do this now."

This is the scenario that turns tax planning from "nice to have" into "urgent." And it's exactly why we model every client's plan through the surviving spouse lens, not just the current year.

What This Looks Like for My Clients

Before we make any move — a withdrawal, a Roth conversion, a capital gain harvest — we model it. Not just for this year, but across your full retirement horizon — including the surviving spouse scenario.

We project your tax liability year by year: What bracket are you in now? What bracket will RMDs push you into at 73? How does a $75,000 Roth conversion this year ripple through your Medicare premiums in two years? What happens to your spouse's tax bill if you're no longer here?

The answer is almost never "just take money out of your IRA." It's usually a carefully calibrated blend of account types, timed to the calendar year, with an eye on every downstream effect — including the one nobody wants to think about.

We review this annually — because your tax picture changes with income, legislation, and life events. The goal is to pay the least total tax over your retirement and your surviving spouse's retirement. Not the least tax this year.

Common Questions

What is a Roth conversion and should I be doing one? +

A Roth conversion moves money from a traditional IRA (pre-tax) to a Roth IRA (after-tax). You pay income tax on the converted amount now, but the money then grows and is withdrawn tax-free for the rest of your life. Whether you should do one depends on your current tax bracket, your projected future brackets, your RMD exposure, and the surviving spouse scenario. For many retirees in the window between leaving work and age 73, the math strongly favors converting — but the amount and timing matter enormously. We model it before recommending it.

How can I reduce my Required Minimum Distributions? +

The most effective way is to reduce the balance in your tax-deferred accounts before RMDs begin — through strategic Roth conversions during lower-income years. Once RMDs start, Qualified Charitable Distributions (QCDs) can satisfy your RMD without adding to your taxable income. We build a multi-year conversion plan that balances tax cost today against RMD burden later, always factoring in IRMAA thresholds and the surviving spouse scenario.

What order should I withdraw from my retirement accounts? +

The conventional advice — draw from taxable first, then tax-deferred, then Roth last — is an oversimplification that costs many retirees real money. The right order depends on your tax bracket each year, your Social Security timing, IRMAA thresholds, capital gains rates, and your long-term Roth conversion strategy. We build a year-by-year withdrawal sequence that blends all three account types to minimize your total lifetime tax bill — not just this year's.

Will my Social Security benefits be taxed? +

Potentially, yes. Up to 85% of your Social Security benefits can become taxable if your combined income exceeds $44,000 (married filing jointly) or $34,000 (single). Combined income includes your adjusted gross income, nontaxable interest, and half your Social Security benefit. The good news: strategic use of Roth withdrawals and careful withdrawal sequencing can keep your combined income below these thresholds, reducing or eliminating the tax on your Social Security.

How does my retirement income affect my Medicare premiums? +

Medicare uses your modified adjusted gross income from two years prior to determine IRMAA surcharges. A large Roth conversion, unexpected capital gain, or heavy IRA withdrawal in one year can trigger additional Medicare Part B and Part D premiums two years later — potentially $600 or more per month per person. We plan every taxable event with IRMAA brackets in mind, spreading conversions across years to stay below thresholds or timing them strategically when crossing a threshold is unavoidable.
