Master the Roth conversion "Tax Valley" strategy. Learn why paying taxes intentionally during low-income years can save you a fortune in retirement.
Most people think taxes are the enemy. They’ll say things like, “I want to pay as little tax as possible” or “I’ll deal with taxes later.” But here’s the provocative truth:
You should want to pay more taxes.
Not today, necessarily — but strategically, intentionally, and at the right time.
Because every dollar you will ever earn is going to be taxed.
Not “maybe,” not “possibly,” not “depending on what Congress does.”
Every dollar is going to get taxed eventually.
Once you understand that, you can start making smarter long-term decisions — especially when it comes to Roth conversions.
Let’s break down why.
When you earn income, you pay tax one of two ways:
Many people mistakenly believe that contributing to a pre-tax retirement account saves them taxes. It doesn’t. It simply postpones them.
If you defer taxes inside a pre-tax account, that money grows — hopefully a lot — but eventually, when you pull it out:
And if you don’t spend all that money yourself, your spouse or kids will. They inherit the tax bill along with the account.
There’s no scenario where those dollars escape taxation.
So the real question becomes:
That brings us to one of the most powerful retirement planning strategies available: understanding your Tax Valley.
High earners often spend their working years in elevated tax brackets — 32%, 35%, even 37%. While you’re earning significant income, there's usually no room to do Roth conversions efficiently.
But that changes the moment you retire.
When you stop working, several things happen:
That period — from retirement until RMDs kick in — is what we call the Tax Valley.
It’s a temporary window of time when your taxable income dips to a level you may not see again in your lifetime.
Because once RMDs begin, the government forces you to withdraw money from your pre-tax retirement accounts — whether you want to or not.
And those withdrawals can:
In some cases, retirees end up paying more tax in their 70s and 80s than they ever expected — even though they have less discretion over their income.
As of now:
These ages matter because they define how long your Tax Valley may last.
If you retire at 60 and don’t face RMDs until 75, you have 15 years of tax-planning opportunity.
If you retire at 65, you still get a decade.
And those years can be extraordinarily valuable.
When your income drops, you have the opportunity to fill up lower tax brackets strategically.
Think about this:
This is why I say:
Not more tax than necessary…
But more than zero.
Because paying zero tax during your Tax Valley is often wasteful.
Wasting the 12% bracket.
Wasting the 22% bracket.
Wasting one of the only times in your life when you can choose your tax rate.
If you don’t use those low brackets, you lose them forever.
And later, forced RMDs may push you back into the 24–35% brackets — meaning you’re paying significantly more tax on potentially much larger account balances.
That’s the trade-off that catches retirees off guard.
Imagine someone with a large 401(k) who worked in the 35% tax bracket.
After retiring at 60, their income drops to mostly Social Security, interest, and some modest portfolio withdrawals.
Suddenly they have room to convert:
Every year.
If they do nothing, those brackets sit unused.
But when RMDs begin at age 75, they may be forced to withdraw hundreds of thousands of dollars per year — pushing them back into 32%+ territory.
This is why the Tax Valley matters.
A Roth conversion lets you:
This is not about avoiding taxes.
It’s about controlling when you pay them and what rate you pay.
And for many, the period between retirement and RMDs is the lowest-tax window they will ever see again.
If they are strategically chosen taxes, paid during low-income years,
targeting specific brackets you would otherwise waste,
that reduce your lifetime tax exposure…
Then yes.
You absolutely should want to pay more taxes.
Because the alternative is paying far more later — at higher rates, on larger balances, with less control.
This is the heart of smart retirement tax planning.
Roth conversions aren’t right for everyone, but understanding your Tax Valley is essential if you want to:
You will pay taxes on every dollar eventually.
The real question is whether you pay them at 12%… or 35%.
A Roth conversion is the process of moving funds from a pre-tax retirement account, like a Traditional IRA or 401(k), into a Roth IRA. Because the money in the original account has never been taxed, you must pay income tax on the amount you convert in the year the move occurs. Once in the Roth IRA, the money grows tax-free, and qualified withdrawals in retirement are also tax-free.
You should want to pay taxes intentionally during your "Tax Valley"—the years between retirement and the start of Required Minimum Distributions (RMDs). By choosing to pay taxes now at a lower rate (e.g., 12% or 22%), you prevent being forced into much higher tax brackets (e.g., 32% or 35%) later in life when the government mandates withdrawals on potentially much larger account balances.
The Tax Valley is a window of time, usually starting the year after you retire and ending when RMDs begin. During these years, your earned income typically drops significantly, putting you in the lowest tax brackets you may ever see. This provides a strategic opportunity to perform a Roth conversion at a "discounted" tax rate.
Under current laws (SECURE Act 2.0):
Yes. Unlike Traditional IRAs, which often require heirs to pay income tax on inherited distributions within 10 years, a Roth IRA provides tax-free wealth to your beneficiaries. By performing a Roth conversion now, you are essentially prepaying the tax bill so your children or spouse don't have to deal with it later.
While powerful, a conversion isn't for everyone. It requires having the cash on hand (ideally from a non-retirement account) to pay the resulting tax bill. Additionally, a large conversion could inadvertently push you into a higher tax bracket for that year or impact your Medicare premiums (IRMAA). It is always best to consult with a financial advisor to "fill" your current tax bracket without overflowing into the next one.
