The Power of Zero by David McKnight explains how to structure your retirement savings across three “buckets” to minimize or eliminate taxes on your retirement income. The core strategy involves keeping your taxable bucket small (six months expenses), limiting tax-deferred accounts to avoid RMD problems, and maximizing tax-free investments like Roth IRAs and life insurance retirement plans (LIRPs). It’s a practical roadmap for anyone worried about what taxes will do to their nest egg.
If you’re saving for retirement, you’ve probably wondered how much of your money will actually be yours when you stop working. Between 401(k) taxes, Social Security taxation, and required minimum distributions, the IRS has plenty of ways to take a cut.
That’s exactly why David McKnight wrote The Power of Zero. The book lays out a clear strategy for restructuring your retirement savings so you can potentially pay zero federal income tax during retirement. We’ve recommended this book to clients for years because it explains complex tax concepts in plain English and offers a realistic path forward.

The Coming Tax Problem
McKnight opens with a sobering reality check. Social Security, Medicare, Medicaid, and interest on the national debt consume a massive portion of government revenue. With the national debt now exceeding $36 trillion and growing, it’s reasonable to expect tax rates will increase in the future.
The tax cuts from 2017 are scheduled to sunset, and when they do, rates go back up. McKnight argues that if you’re accumulating money in tax-deferred accounts, you’re essentially building a tax time bomb. You don’t know what tax rates will be when you withdraw that money in 20 or 30 years.
His solution? Structure your savings so withdrawals don’t count as taxable income at all.
The Three-Bucket Strategy
The heart of the book is McKnight’s three-bucket approach to retirement savings. Each bucket serves a specific purpose, and getting the balance right is crucial.
The Taxable Bucket
This is your emergency fund. McKnight recommends keeping exactly six months of living expenses here, no more. These are liquid funds in savings accounts, CDs, or similar vehicles. You’ll pay taxes on any interest or gains, so you don’t want excess money sitting in this bucket. It’s purely for unexpected expenses and short-term needs.
The Tax-Deferred Bucket
This includes your 401(k), traditional IRA, and similar accounts. Most people pour money into these accounts because contributions are tax-deductible. The problem? Every dollar you withdraw in retirement gets taxed as ordinary income.
Here’s where it gets tricky. Once you turn 73, you’re required to take minimum distributions whether you need the money or not. If your tax-deferred bucket is too large, those RMDs can push you into a higher tax bracket and even trigger taxes on your Social Security benefits.
McKnight’s advice is counterintuitive for many people. He suggests limiting your tax-deferred contributions to what your employer will match. Anything beyond that? Put it somewhere else.
The Tax-Free Bucket
This is where the real planning happens. McKnight focuses on two primary vehicles that qualify as truly tax-free: Roth IRAs and Life Insurance Retirement Plans (LIRPs).
For an investment to qualify for the tax-free bucket, it needs to meet two criteria. First, distributions must be free from federal, state, and capital gains taxes. Second, the income can’t count as provisional income that would trigger Social Security taxation.
Municipal bonds, for example, don’t make the cut. While they’re free from federal tax, the interest counts as provisional income. Roth IRAs and properly structured LIRPs meet both requirements.
Why the Roth IRA Matters
McKnight calls the Roth IRA his favorite tax-free investment. If you’re 59½ or older, qualified distributions are completely tax-free. They don’t count as provisional income, so they won’t affect your Social Security benefits.
The catch is that Roth IRAs have contribution limits and income restrictions. If you earn too much, you can’t contribute directly. And even if you qualify, the annual contribution limits mean you can only shelter so much money each year.
For high earners or people who got a late start on retirement planning, the Roth IRA alone won’t get you to the zero percent tax bracket. That’s where the LIRP comes in.
The Life Insurance Retirement Plan
Chapter five of the book is where things get interesting for us. McKnight dedicates significant space to what he calls the LIRP, a life insurance retirement plan built using permanent life insurance.
Here’s how it works. You fund a life insurance policy, typically an indexed universal life policy, with the goal of building cash value rather than maximizing the death benefit. Your money grows tax-deferred inside the policy. When you’re ready to access it in retirement, you take loans against the cash value rather than withdrawals.
Policy loans aren’t considered income by the IRS. They don’t count as provisional income. There are no contribution limits like with a Roth IRA, and no income restrictions. McKnight points out that about 85% of Fortune 500 CEOs use this strategy as part of their retirement planning.
We’ve been helping clients set up these policies for over 30 years. When structured correctly with an indexed universal life policy, you get the potential for market-linked growth without the downside risk, plus tax-free access to your money in retirement. It’s not for everyone, but for people who’ve maxed out their Roth options or don’t qualify due to income limits, it fills an important gap.
Getting the Balance Right
McKnight is clear that all three buckets have a role to play. The key is keeping them in balance.
Your taxable bucket should hold six months of expenses. Period. If you’ve hit that target and you’re still contributing to savings accounts, redirect that money to your tax-free bucket.
Your tax-deferred bucket should be sized so that your required minimum distributions at 73 will be at or below your standard deduction. This way, your RMDs won’t trigger any federal income tax. If you’re contributing more than your employer match to a 401(k), consider redirecting the excess.
Your tax-free bucket should hold the rest. The more you can accumulate here, the more flexibility you’ll have in retirement to withdraw money without tax consequences.
The Bottom Line on The Power of Zero
McKnight makes a compelling case that tax planning should be central to retirement planning. It’s not just about how much you save. It’s about how much you keep.
The book is an easy read, and McKnight does a good job breaking down concepts that would otherwise require a financial advisor to explain. If you’re concerned about what rising tax rates might do to your retirement income, this book gives you a framework for protecting yourself.
We’d also recommend McKnight’s follow-up books, Look Before You LIRP and The Volatility Shield, if you want to dive deeper into the insurance-based strategies he introduces here.
Frequently Asked Questions
What is the power of zero strategy?
The power of zero is a retirement planning approach that aims to structure your savings so you pay little or no federal income tax during retirement. It involves balancing three buckets of money: taxable, tax-deferred, and tax-free. By keeping the right amounts in each bucket, you can potentially withdraw retirement income without triggering taxes.
Is The Power of Zero worth reading?
Yes, especially if you’re concerned about taxes eating into your retirement savings. David McKnight explains complex tax concepts clearly and offers actionable strategies. It’s a quick read that can change how you think about 401(k)s, Roth IRAs, and life insurance as retirement tools.
What is a LIRP and how does it work?
A LIRP, or life insurance retirement plan, uses permanent life insurance to build tax-free retirement income. You fund a policy designed to maximize cash value growth. In retirement, you access that cash through policy loans, which aren’t considered taxable income. It’s particularly useful for people who earn too much to contribute to a Roth IRA.
How much should I have in each bucket?
McKnight recommends six months of living expenses in your taxable bucket, enough in your tax-deferred bucket so RMDs stay below your standard deduction, and as much as possible in your tax-free bucket. The exact amounts depend on your income, expenses, and retirement timeline.
Does the three-bucket strategy actually work?
The underlying tax principles are sound. Roth distributions and properly structured life insurance loans are tax-free under current tax law. The strategy requires discipline and long-term commitment, but for people who implement it correctly, it can significantly reduce lifetime tax liability.
Key Takeaways
- Tax rates will likely increase as the government addresses the national debt, making tax-free retirement income more valuable.
- Three buckets work together to create tax-efficient retirement income: taxable (six months expenses), tax-deferred (limited), and tax-free (maximized).
- Roth IRAs are powerful but have contribution and income limits that prevent many people from accumulating enough.
- Life insurance retirement plans fill the gap for high earners or late starters who need additional tax-free accumulation.
- Balance matters because too much in any one bucket can create tax problems or limit your flexibility.
