How to Fund Your 3 Retirement Buckets Tax-Efficiently
Over the past few weeks, we’ve been building a more organized way to think about retirement money. First, we separated assets into Live On and Leave On buckets. Then we added a third bucket — the Early Retirement Income Bucket — to help protect against sequence of returns risk in the early years of retirement.
Today, we’re taking this framework one step further by exploring how to fund these three buckets tax-efficiently.
While having a general withdrawal order (taxable, tax-deferred, and tax-free) can be helpful as a starting point, the 3-bucket approach gives us a more nuanced way to think about where the money should come from when funding or replenishing each bucket. The right strategy depends on your specific tax situation, your goals, and how each bucket is currently funded.
The 3-Bucket Framework (Quick Recap)
- Bucket 1 – Early Retirement Income Bucket: Covers your spending needs for the first 3–5 years of retirement. Designed to protect against sequence of returns risk by keeping this money in more conservative investments.
- Bucket 2 – Longer-Term Live On Bucket: Holds the money you’ll spend from roughly year 6 through the rest of retirement. This bucket has a longer time horizon and can be invested more aggressively.
- Bucket 3 – Leave On Bucket: Contains money you likely won’t need to spend and intend to pass on to your children and grandchildren.
Tax-Efficient Funding Strategies by Bucket
Bucket 1: Early Retirement Income Bucket
There are two main schools of thought here. One approach is to fund this bucket primarily from taxable accounts first, since long-term capital gains and qualified dividends are typically taxed at lower rates. This can help you avoid higher ordinary income tax brackets and IRMAA surcharges early in retirement.
However, there’s also a strong case for strategically using tax-deferred money (traditional IRA or 401k) in this bucket — especially during early retirement years when many people are in lower tax brackets. Withdrawing from traditional accounts now can reduce the size of your IRA before RMDs begin, which may lower future Required Minimum Distributions and reduce the tax burden on your heirs under the 10-year rule.
Bucket 2: Longer-Term Live On Bucket
This bucket often presents excellent opportunities for tax planning. Roth conversions can be very powerful here, especially in years when you’re in a lower tax bracket. Moving money from traditional accounts into a Roth can create tax-free growth and withdrawals later on.
In some cases, it may also make sense to strategically withdraw from tax-deferred accounts (instead of converting) to fill up lower tax brackets without pushing into higher ones or triggering IRMAA. This approach can help shrink your traditional IRA over time while still keeping your tax bill manageable.
Bucket 3: Leave On Bucket
If legacy planning is important to you, this bucket is often a strong candidate for Roth conversions. Converting money into a Roth allows you to potentially leave your heirs tax-free assets rather than forcing them to deal with the 10-year withdrawal rule on a large traditional IRA. Other legacy strategies, such as life insurance or certain trusts, can also be considered.
Key Principles for Tax-Efficient Bucket Funding
- Think in terms of tax rate arbitrage — try to pay taxes in lower-rate years when possible.
- Be mindful of secondary consequences, such as IRMAA surcharges and the taxation of Social Security.
- Recognize that this is not a “set it and forget it” decision. Your funding strategy should be reviewed and adjusted over time as your situation changes.
Why Personalization Matters
One of the biggest mistakes people make is applying generic withdrawal strategies without running the numbers on their specific situation. The right way to fund these buckets will look different for everyone, depending on current and future tax brackets, the size of your accounts, spending needs, and legacy goals.
This is exactly why building a Smart Retirement Model can be so valuable. When you can see how different funding decisions impact your taxes, your probability of success, and what you leave behind, it becomes much easier to make confident, personalized decisions.
