Strategic Tax Planning for Early Retirement: Making the Most of Your Low-Income Years

You’ve probably spent decades in pursuit of your “number” — the amount that lets you live off retirement savings.

But there’s another number to plan around: the years between when you retire and when required minimum distributions begin at age 73.

This window, which typically spans your early 60s through age 72, represents the most valuable tax planning opportunity most retirees will ever have. Income is lower than it’s been in decades. Withdrawals are at your discretion. And strategic decisions can help save hundreds of thousands in lifetime taxes.

These are the tax transition years. And how you use them can impact the longevity of your retirement accounts.

Why the Window Before Age 73 Is Important

Once you stop working, you lose your paycheck — but you gain tax flexibility. 

At age 73, everything changes. Required minimum distributions (RMDs) kick in, forcing you to make taxable withdrawals from traditional IRAs and 401(k)s plans. By then, your tax-deferred accounts have likely grown another decade, which means larger RMDs, higher tax brackets, and less control over your taxable income.

Three factors converge during the tax transition years to create planning opportunities:

• Lower income. Without a paycheck and before claiming Social Security, your taxable income is at its most manageable level in decades. This allows you to intentionally realize income at favorable rates — converting funds, realizing gains, or withdrawing strategically — without spiking into higher rates.
• Control over withdrawals. Before RMDs begin, you decide how much to take from retirement accounts and when. Once RMDs start, the government sets a minimum for you. 
• Medicare considerations. If you’re 65 or older, income thresholds determine whether you’ll pay Medicare surcharges (IRMAA). Each IRMAA tier can add thousands of dollars per person, per year. Large withdrawals or conversions can trigger premium increases two years later. Planning during your early 60s, before Medicare enrollment, gives you more flexibility to execute tax strategies without penalty.

This is why coordination matters. Federal taxes, state taxes, Medicare premiums, and Social Security taxation are all connected. Let’s walk through the strategies that work best during this period.

Strategy #1: Strategic Roth Conversions

A Roth conversion moves funds from a traditional IRA or 401(k) into a Roth IRA. You pay taxes now on the converted amount. In exchange, the money grows tax-free and can also be withdrawn tax-free down the road.

Tax rates are not static. That’s precisely why the first five years of retirement are often ideal for conversions.

If you are in a lower bracket at 62 than you expect to be at 75, paying taxes at 12% or 22% today may be far more attractive than paying 24% or 32% later.

How to Execute Roth IRA Conversions

Instead of converting a random amount, we map conversions to “fill” the top of a chosen tax bracket without spiking your rate.

For example, if you’re married and your taxable income (after deductions) is $60,000, you have about $34,000 of space left in the 12% bracket before jumping to the 22% bracket ($94,000). Converting $34,000 keeps you in the lower bracket and minimizes your tax bill.

Repeat this process over several years, and you can systematically reduce your traditional IRA balance, lowering future RMDs and creating a pool of tax-free income to draw from later.

Medicare Considerations 

If you’re already on Medicare, conversions count as income and can trigger IRMAA surcharges two years later. Before age 65, you have more flexibility. After 65, model conversions carefully to stay under IRMAA thresholds (currently $109,000 for single filers, $218,000 for married couples).¹

Strategy #2: Capital Gains Harvesting

Long-term capital gains (i.e., profits from investments held over a year) receive preferential tax treatment. And during low-income years, you may qualify for the 0% capital gains rate.

For 2026, the 0% rate applies to single filers with taxable income under approximately $49,450 and married couples under $98,900.² If your income falls within these thresholds, you can sell appreciated investments, pay zero federal tax, and reset your cost basis. The proceeds can be reinvested immediately.

Once RMDs and Social Security ramp up, your income will likely exceed these limits. The 0% rate disappears, and future gains are taxed at 15% or higher.

Stacking Considerations

Capital gains count toward your total taxable income, which affects whether you qualify for the 0% capital gains rate and whether you trigger Medicare surcharges.

If you convert $30,000 from a traditional IRA and realize $30,000 in long-term capital gains, your combined income is $60,000. That could push you into the next capital gains threshold (if you’re single or file separately), meaning $10,550 of those gains are now taxed at 15% instead of 0%. 

For larger conversions, say $80,000 combined with $30,000 in gains, you’re also creating potential IRMAA issues if you’re over 65, since the first threshold is $109,000 for singles.

Model combined strategies carefully. In some cases, it makes sense to harvest gains one year and execute conversions the next, rather than stacking both in a single tax year.

Strategy #3: Optimizing Withdrawal Sequencing

Some retirees default to withdrawing only what they need from whichever account feels convenient. That approach can lead to missed opportunities. In the transition years, you control where your income comes from. Later, once RMDs start, the IRS takes partial control.

The conventional sequence for tax-efficient withdrawals:

1. Taxable accounts first. Brokerage accounts benefit from favorable long-term capital gains rates. Drawing from these accounts early preserves tax-advantaged accounts and keeps taxable income low.
2. Traditional IRA withdrawals as needed. Once taxable accounts are depleted or to balance cash flow, tap traditional IRAs. Keep in mind that withdrawals are taxed as ordinary income.
3. Roth conversions to fill bracket space. If you have room in lower tax brackets (12% or 22%) after covering expenses, consider converting traditional IRA funds to Roth. This reduces future RMDs while unlocking tax-free income for later.
4. Roth accounts last. Leave Roth IRAs untouched to grow tax-free. These accounts have no RMDs and provide flexibility later in retirement.

The bracket-filling principle works best with Roth conversions: if you’re in the 12% bracket and only need $40,000 from your portfolio for expenses, you might have room to convert an additional $10,000 to Roth at that same 12% rate and reduce future taxes. 

Strategy #4: Medicare and IRMAA Planning

Medicare introduces a two-year lookback for premium calculations, known as the IRMAA (Income-Related Monthly Adjustment Amount). If your modified adjusted gross income exceeds certain thresholds, you pay higher Part B and Part D premiums. Each IRMAA tier adds about $1,200 to $8,200+ annually per person, depending on income level, and those premiums add up over time.

For retirees already on Medicare, this presents a planning challenge: a large Roth conversion, real estate sale, or concentrated stock liquidation can trigger a premium increase two years from now. 

Here’s how to plan around it:

1. If you retire early, execute large conversions before the IRMAA lookback window. If you retire at 60–62 and plan to enroll in Medicare at 65, those early retirement years (when income is low) are ideal for conversions — but you need to complete them by age 62 to fall outside the 2-year lookback. Conversions at 63 or 64 could trigger IRMAA surcharges when Medicare begins. 
2. If already on Medicare, model income to stay under thresholds. IRMAA brackets reset annually, so coordinating conversions, property sales, or other income events with these limits can prevent unnecessary premium increases.
3. Coordinate with other financial planning events. If you’re selling a business, downsizing a home, or claiming a large bonus, time these events strategically to avoid compounding income spikes.

Common Mistakes That Lock In Higher Lifetime Tax Liabilities

Even well-intentioned retirees make missteps during the transition years. Here are the most costly ones:

1. Waiting until RMDs force action. By age 73, your traditional accounts have compounded for another decade. RMDs can become large enough to push retirees into higher brackets permanently, and by this point, you will have lost the flexibility to manage distributions strategically.
2. Converting too aggressively in one year. A single large conversion spikes income, potentially pushing you into higher brackets and triggering Medicare surcharges. Spreading conversions across multiple years keeps rates lower and avoids penalties.
3. Ignoring capital gains harvesting. The 0% capital gains rate is an opportunity during low-income years. 
4. Not coordinating withdrawals with Social Security benefits. If you claim Social Security early while executing large Roth conversions, you’re adding two income sources in the same years — potentially pushing yourself into higher brackets and making more of your Social Security taxable. For those who can afford to delay benefits, keeping Social Security off the table during high-conversion years allows you to manage retirement income more efficiently, then increase guaranteed income later. But this strategy requires sufficient portfolio assets to cover expenses while delaying, so it’s not the right approach for everyone.
5. DIY retirement planning without modeling ripple effects. Every financial decision affects multiple areas: federal income taxes, state taxes, Medicare premiums, and Social Security taxation. 

Every Year Counts

While it’s true that your tax transition window is wide, each year you wait is one fewer to execute tax-efficient strategies.

If you’re between ages 60 and 72, review your tax situation now. Model Roth conversions, capital gains taxes, and withdrawal sequencing to see what’s possible.

If you’re approaching retirement, start planning two to three years before leaving the workforce, so you can coordinate your income events with your exit strategy and tax plan. 

And if you have already entered your 70s, there may still be opportunities within the remaining window. It simply requires careful analysis.
