Among the many complaints about the U.S. tax system, one of the biggest is simply figuring out how much you actually owe in a given year. With each new piece of tax legislation passed and novel deduction introduced, estimating tax liability has become increasingly complicated, particularly for those with unpredictable income.
For individuals with consistent income sources, such as W-2 wages or Social Security benefits, taxes are generally straightforward and can simply be withheld evenly throughout the year. For others, who have less predictable sources of income, such as interest, dividends, capital gains, and/or self-employment income or K-1 business distributions, estimating tax liability becomes less clear.
These types of income typically do not allow for direct tax withholding, yet the levy is still expected to be paid as the income is earned. As a result, many taxpayers rely on quarterly estimated payments.
If those quarterly estimates are inaccurate, or what we more commonly see, simply never paid, taxpayers may face IRS underpayment penalties. Which is where the “Erase and Replace” strategy can come into play.
Understanding Quarterly Estimated Tax Payments vs. Tax Withholding
Before diving into the strategy, it’s important to understand quarterly estimated tax payments and tax withholding.
Quarterly Estimated Tax Payments
As noted earlier, income sources without a withholding mechanism (interest, dividends, capital gains, self-employment income and K-1 business distributions) generally require individuals to remit their estimated tax payments directly to the IRS roughly every quarter. See table below:
If sufficient taxes are not paid, and safe harbor thresholds are not met, the IRS may assess underpayment penalties. The penalty is an interest rate charged by the IRS and applied to any unpaid balance that was not remitted by its due date. Per the Internal Revenue Code, the underpayment rate is equal to the applicable federal short-term rate (rounded to the nearest whole number) plus 3%. For example, the current underpayment rate is 6%.
Some taxpayers intentionally delay their quarterly payments, preferring not to part with their dollars early and keep them invested for longer. While this approach can work in their favor during strong markets, it can easily backfire if the market declines instead. With interest rates remaining elevated, outperforming the underpayment rate (currently 6%) is far from guaranteed, so this approach should be considered carefully.
Tax Withholding
Taxes withheld from W-2 wages, Social Security benefits, and pre-tax retirement account distributions are treated differently than quarterly estimated tax payments.
With W-2 wages and Social Security benefits, both the income and associated tax withholding (if elected) are often paid evenly throughout the year. Pre-tax retirement account distributions, however, offer significantly more flexibility, as the account owner can choose when and how frequently distributions are taken.
For example, an individual could elect to take monthly distributions from their pre-tax retirement account throughout the year and withhold taxes incrementally. Alternatively, they could wait until year-end, take one large distribution, and elect to withhold taxes at that time.
Since withheld taxes are treated as if they’ve been paid evenly throughout the year, regardless of when the withholding actually occurs, taxpayers can avoid underpayment penalties, provided the total amount paid is sufficient.
Estimated tax payments do not receive this same treatment. If a taxpayer underpays throughout the year and later attempts to catch up by making a large, estimated payment near year-end, the IRS can still assess penalties for the earlier quarters in which taxes were not timely paid.
That distinction creates a unique tax planning opportunity referred to as the “Erase and Replace” strategy.
How the “Erase and Replace” Strategy Works
The strategy is a two-step process:
Step 1: The “Erase”
The taxpayer takes a distribution from a pre-tax retirement account, such as a traditional IRA, and withholds a substantial portion, often 100%, for taxes.
Since withholding is treated as though it occurred evenly throughout the year, this can effectively “erase” potential underpayment penalties, even if the withholding happens late in the year.
This step is typically executed near year-end, once income and tax liability for the year are better understood. In addition to potentially reducing underpayment penalties, it allows the taxpayer to retain their funds longer (since they’ve opted out of making quarterly estimated payments), with the opportunity to earn additional investment income.
Step 2: The “Replace”
Next, the taxpayer replaces the distributed funds by redepositing the gross distribution amount back into the retirement account using separate, non-retirement dollars (i.e., dollars that would have otherwise been used for quarterly estimates) via a 60-day rollover.
If executed properly, this step allows the taxpayer to use the retirement distribution to satisfy their tax obligation without further increasing taxable income, and eliminating potential early withdrawal penalties should they be below age 59.5, since the distributed amount is being “replaced” within 60 days.
It’s important to note that only one 60-day rollover is permitted within a rolling 12-month period. This is strictly enforced, and if missed, the entire distribution becomes fully taxable, even if a significant portion was withheld for taxes, potentially increasing taxable income and undermining the strategy entirely. Because of this, sufficient liquidity outside of retirement accounts is essential to successfully complete the replacement step.
Who Might This Strategy Work For?
Though the use case for the “Erase and Replace” strategy is relatively narrow, it offers individuals an opportunity to earn additional investment income on funds that otherwise would have been paid to the IRS much earlier in the year. The strategy may be worth considering for individuals with the following fact pattern:
- Missed or underfunded quarterly estimated payments and a desire to mitigate potential underpayment IRS penalties
- A high-income year, driven by:
- Interest, dividends, or capital gains
- Self-employment income / K-1 business distributions
- A business sale
- A real estate sale
- Or other significant liquidity events
- A requirement to make large quarterly estimated tax payments
- A sizable pre-tax retirement account balance (for the “Erase” portion)
- Sufficient non-retirement assets available (for the “Replace” portion)
A Practical Example
In a scenario like this, an individual could hold the funds earmarked for their annual tax liability in a non-retirement account throughout the year, investing conservatively in vehicles such as money market funds, short-term Treasuries or Municipal bonds. Meanwhile, their retirement account remains fully invested in a long-term strategy.
Then, near year-end, the individual would:
- Take a distribution from their pre-tax retirement account equal to their projected tax liability, withholding up to 100% of the distribution for taxes
- Replace the gross distribution amount using their non-retirement assets via a 60-day rollover
- Reinvest those replacement dollars back into the pre-tax retirement account according to their long-term investment strategy
If executed properly, this will:
- Eliminate or reduce underpayment penalties
- Allow the taxpayer to retain control of their funds longer during the year
- Generate incremental interest income while those dollars (earmarked for taxes) remain invested conservatively in their non-retirement account
Some may consider investing these dollars earmarked for taxes in their non-retirement more aggressively in an effort to capture higher returns while retaining them longer. However, because the funds are needed within a short timeframe, exposing them to meaningful market volatility could create unnecessary risk if markets decline before the taxes are due. For that reason, a conservative approach, with very little risk to principal, is more appropriate.
Bottom Line
While the “Erase and Replace” strategy can be effective for taxpayers who meet the criteria listed above, it is not universally appropriate. For individuals making modest quarterly estimated payments, the potential risks, particularly around missed deadlines and the resulting IRS penalties, may outweigh the incremental benefits.
After all, the main benefit is simply eliminating potential underpayment IRS penalties and/or earning additional investment income on funds that would have otherwise been paid to the IRS earlier in the year. For many, that alone may not justify the complexity.
That said, when used in the right context, the strategy can optimize cash flow and modestly enhance overall returns. While it is not a standalone solution for achieving financial goals, it can add incremental value when executed properly.
Given the strict deadlines and potential consequences of errors, working with an advisor or tax professional is essential to ensure proper execution.
