Mike and Liz's retirement surprise

After retiring at 63 with nearly $2 million saved mostly in traditional IRAs and 401(k)s, they expected simple taxes. Their adviser suggested something unexpected: a large Roth conversion.

“Why would we voluntarily pay more taxes right now when our income is finally so low?”

The golden tax planning window

Between retirement and required minimum distributions at age 73, you're in a low-income period. This window is your chance to convert traditional retirement accounts to Roth at lower tax rates.

“This may be the lowest tax rate you see for the rest of your retirement.”

Your window isn't one-size-fits-all

The golden window starts when you stop getting a paycheck and ends when taxable income kicks in like Social Security, pensions, or RMDs. Some retirees get one or two years, others get five to ten.

Not everyone gets a window

If you have a large pension, deferred compensation, passive income from business or rental property, or significant capital gains, you might not have a golden window at all.

Why Roth conversions matter

During working years, you lower current taxes with traditional IRA and 401(k) contributions. In retirement, Roth conversions shift that strategy: pay taxes now at low rates to avoid higher taxes later.

Two common Roth conversion myths

Many retirees think they can't convert without earned income or that converting large balances creates huge tax bills. Both are wrong. You can convert any amount without income, and you choose how much to convert.

“I can't Roth convert. I don't have any income.”

The golden rule of conversions

Choose the right year and the right amount. Convert when today's tax rate is lower than your projected future withdrawal rate. Your golden window helps identify both.

“Choose the right year and the right amount of Roth conversions.”

How your window closes

As Social Security, pensions, and RMDs start, your window shrinks. Once RMDs begin, the added taxable income can make more of your Social Security taxable, pushing you into higher brackets.

The widow's penalty trap

When a spouse dies, the survivor moves from married filing jointly brackets to single filer brackets. Income doesn't drop proportionally, so the surviving spouse often faces higher tax rates and a tax hit called the widow's penalty.

Don't convert everything at once

Mike and Liz wanted to convert their entire nest egg immediately. Their adviser said no. Converting too much in one year could push them into higher brackets and waste their golden window.

“Should we convert our whole nest egg right now? Not yet.”

Taxes are just one piece

Roth conversions matter, but they're part of a bigger picture. You also need to coordinate Social Security timing, pension decisions, spending plans, investments, and estate planning.

Map your future tax rates

Mike and Liz projected their taxes for each year of their expected 30-year retirement. They identified years with lower and higher tax rates, then targeted conversions for the lower-rate years.

Plan conversion amounts and timing

Once you see your projected tax rates, you can determine how much to convert each year and how to handle tax withholding. This prevents surprises and maximizes your golden window.

Don't wait until RMD time

Many retirees delay tax planning until required minimum distributions start. By then, your window has closed. Project your taxes now and at each major life change like starting Social Security or pensions.

“When you hit retirement, don't just push off your tax decisions until RMD time.”

Identify your window before it closes

Find out whether your golden tax planning window is open, how long it will stay open, and how much you can convert each year. This requires looking ahead, not waiting for tax time.
