Ed Slott believes most Americans should not contribute to traditional 401(k)s. His recent essay on the subject is a great opportunity for the FI community to reassess its love for the traditional 401(k).

My conclusion is that for many in the FI community, traditional deductible 401(k) contributions are still the most logical path when it comes to workplace retirement saving. Below I explain my thinking. 

It is important to note it is impossible to make a blanket statement as applied to the entire FI community. 

Why the Traditional 401(k) Is Good for the FI Community

Many in the FI community have the very reasonable hope that in retirement they will have years, possibly decades, where their effective tax rate will be lower than their marginal tax rate in their working years. 

The above is true of many Americans, but it is particularly true if one retires early by conventional standards. The idea is deduct, deduct, deduct into the 401(k) during one’s working years (particularly the high earning years) and then retire early by conventional standards. Prior to collecting Social Security and/or required minimum distributions (“RMDs”), most retirees look artificially poor on their tax return. This opens up the door to affirmatively convert money from traditional retirement accounts to Roth accounts and pay tax at the lowest federal income tax brackets (currently 10% and 12%). For those who deducted contributions into the 401(k) at a 24% or greater marginal federal tax rate, this is great tax rate arbitrage planning.

Minor litigation risks aside, this strategy just got even easier for those born in 1960 and later, who don’t have to take RMDs under SECURE 2.0 until age 75. With the new delayed RMD beginning date, even those retiring as late as age 65 will have a full decade prior to being required to take RMDs to do tax-efficient Roth conversions at low marginal tax rates. For some in the FI community, this opportunity window might not be a decade long but rather a quarter-century long (if they retire at age 50). 

How Bad is the Retiree Tax Problem?

As wonderful as FI tax rate arbitrate planning might be, Ed Slott’s concern that retiree taxes will increase is not entirely unwarranted. It is obvious that the government is not fiscally responsible, and it is obvious that tax increases could be coming in the future. 

Let’s assess the situation by looking at just how bad the problem of taxes is in retirement.

We begin with a baseline case. David and Hannah are in their 70s. They never did Roth conversions in early retirement and have the bulk of their financial assets in traditional IRAs and traditional 401(k)s. During most of their working years, David and Hannah maxed out 401(k)s and got deductions in the 24% bracket or greater. For 2023, they have taxable RMDs of $160,000, Social Security of $40,000, $4,000 of qualified dividends and $1,000 of interest income. How bad is their federal income tax situation?

Federal Income Tax Return
RMDs	$ 160,000
Social Security	$ 40,000
15% Social Security Exclusion	$ (6,000)
Interest	$ 1,000
Qualified Dividends	$ 4,000
Adjusted Gross Income (“AGI”)	$ 199,000
Standard Deduction	$ (27,700)
Additional SD Age 65+	$ (3,000)
Federal Taxable Income	$ 168,300
Federal Income Tax (Estimated)	$ 27,361
Effective Tax Rate on AGI	13.75%
Marginal Federal Income Tax Rate	22%

Under today’s rules, David and Hannah, who did no tax planning other than “deduct, deduct, deduct” are doing great. Their federal effective tax rate, even with $200K of RMDs and Social Security, is just 13.75%. They incur such a low effective tax rate because their RMDs go against the 10% tax bracket, the 12% bracket, and the 22% bracket. 

While I do think David and Hannah would be in a better position had they done some tax efficient Roth conversion planning earlier in retirement, their unbridled enthusiasm for traditional retirement accounts served them well. 

Note: David and Hannah are borderline IRMAA candidates: a $199K 2023 AGI might cost them approximately $2,000 in IRMAA surcharges in 2025 (but it is possible that inflation adjustments for 2025 will prevent that from happening). This is another reason to consider pre-RMD Roth conversions at lower marginal tax rates. 

Update 8/19/2023: But what about the widow’s tax trap? If David or Hannah die, won’t the survivor get crushed by tax increases? Check out this estimate. Assuming the survivor loses the lower-earning spouse’s Social Security benefits of at least $10,000, the survivor’s marginal federal income tax rate would climb from 22% all the way up to . . . 24%!

But what about future tax increases? Okay, let’s add four tax increases to the picture and see just how bad it looks:

1. Eliminate the TCJA increase to the standard deduction (the law reverts to pre-2018 lower standard deduction and personal exemptions). This would reduce David and Hannah’s deductions by roughly $2,740, costing them approximately $602.80 in additional federal income tax (at today’s 22% marginal tax rate).
2. Eliminate the TCJA decrease in the 15% tax bracket to 12%. This would cost David and Hannah $2,023.50 in additional federal income tax. I’m highly skeptical that either of these two tax increases will actually occur, but as written in today’s laws they are scheduled to happen in 2026. 
3. Increase the 15% long term capital gains and qualified dividend income rate to 25%. While I believe that the real risk is an increase in the 20% long term capital gains and qualified dividend income rate, let’s stress test things and consider a large increase in the 15% rate. In David and Hannah’s case, this costs them $400 in additional federal income tax.
4. Increase the 22% tax rate to 33%. Ed Slott is worried about large tax rate increases, so let’s consider one that I believe is politically infeasible, a 50% increase in the 22% tax bracket. This type of tax rate increase would hit millions of voters in a major way. But it’s helpful to consider what could be a worst case scenario. In this case, this tax rate increase costs David and Hannah an additional $8,233.50 in federal income tax.
5. There’s one more tax hike to consider: the combination of tax increases numbers 1 and 4. If both occurred together, combined they would cost David and Hannah an additional $301.40 in federal income tax. 

Here’s what David and Hannah’s federal tax picture looks like if all of the above tax increases occur:

Federal Income Tax Return
RMDs	$ 160,000
Social Security	$ 40,000
15% Social Security Exclusion	$ (6,000)
Interest	$ 1,000
Qualified Dividends	$ 4,000
Adjusted Gross Income (“AGI”)	$ 199,000
Standard Deduction	$ (15,240)
Additional SD Age 65+	$ (3,000)
Personal Exemptions	$ (9,720)
Federal Taxable Income	$ 171,040
Federal Income Tax (Estimated)	$ 38,922
Effective Tax Rate on AGI	19.56%
Marginal Federal Income Tax Rate	33%

Significant tax increases hurt David and Hannah, but how much? By my math, very significant tax increases, including a 50% increase in the 22% bracket, cost them about 6% of their income. Not nothing, but wow, they’re still doing very well. 

Yes, on the margin, the last dollars David and Hannah contributed to the traditional 401(k) were not ideal since they faced a 33% marginal federal tax rate in retirement. But let’s remember (i) their overall effective rate is still more than 4 percentage points lower than their working years’ marginal rate (at which they deducted their 401(k) contributions), (ii) they have income significantly above what most Americans will have in their 70s, and (iii) in my scenario they face four separate tax hikes and still pay a federal effective tax rate less than 20 percent.

Future Retirees’ Tax Risk

Do future tax hikes pose no threat to future retirees? Absolutely not! But my stress test shows that many Americans with substantial RMDs will not get walloped even if Congress enacts unpopular tax increases. Considering many in the FI community will have modest RMDs due to pre-RMD Roth conversions, the threat of future tax hikes is even less perilous for the FI community.

Further, many Americans, particularly those in the FI community, have a great tool that can mitigate this risk: Roth conversions during retirement! With RMDs now delayed to age 75 for those born in 1960 and later, many Americans will have years if not decades where money can be moved in a tax-efficient manner from old traditional accounts to Roth accounts. 

Further, many Americans can claim deductions at work and then at home contribute to a regular Roth IRA or a Backdoor Roth IRA. This too mitigates the risk of having all of one’s retirement eggs in the traditional basket. 

Last, do we really believe that Congress is just itching to raise taxes on future retirees? Sure, it’s possible. But to my mind taxes are more likely to be raised on (i) those in higher ordinary income tax brackets and/or (ii) long term capital gains and/or qualified dividends (particularly the current 20% bracket). If anything, the most Congress is likely to do to retirees is slightly increase their taxes so as to mitigate the political risk involved in raising taxes on retirees who tend to vote. 

The Risks of Not Having Money in Traditional Retirement Accounts

Risk isn’t a one-way street. There are some risks to not having money in traditional retirement accounts. I identify three below.

Qualification for Premium Tax Credits

Picture it: Joe, age 55, retires with the following assets: (i) a paid off car, (ii) a paid off house, (iii) a $40,000 emergency fund in an on-line savings account, and (iv), $2 million in Roth 401(k)s and Roth IRAs. He heard that Roth is the best, so he only ever contributed to Roth IRAs and Roth 401(k)s, including having all employer contributions directed to a Roth 401(k). Having fallen into the Rothification Trap, in retirement Joe must work in order to generate sufficient taxable income to qualify for any ACA Premium Tax Credit. 

For at least some early retirees, the ability to create modified adjusted gross income by doing Roth conversions will be the way they guarantee qualifying for significant Premium Tax Credits to offset ACA medical insurance premiums. 

Charitable Contributions

Many Americans are at least somewhat charitably inclined. Starting at age 70 ½, Americans can transfer money directly from a traditional IRA to a charity, exclude the distribution from taxable income, and still claim the standard deduction. Essentially, if you’re charitably inclined, at a minimum you would want to go into age 70 ½ with enough in your traditional IRAs (likely through contributions to traditional 401(k)s that are later transferred to an IRA) to fund your charitable contributions from 70 ½ until death. 

Why ever pay tax on that money (i.e., by making contributions to a Roth 401(k) that are later withdrawn to be donated) if the money is ultimately going to charity anyway?

Unused Standard Deductions

Currently, the government tells married couples, hey, you get to make $27,700 a year income tax free! Why not take advantage of that exclusion every year, especially prior to collecting Social Security (which, in many cases will eat up most, if not all, of the standard deduction). 

Why be retired at age 55 with only Roth accounts? By having at least some money in traditional retirement accounts going into retirement, you ensure you can turn traditional money into Roth money tax-free simply by converting (at any time) or even distributing (usually after age 59 1/2) the traditional retirement account against the standard deduction. 

Deduct at Work, Roth at Home

I think for many it makes sense to max out traditional 401(k)s at work and contribute to Roth IRAs or Backdoor Roth IRAs at home. Why? As discussed above, traditional 401(k)s can set up tax rate arbitrage in retirement, help early retirees qualify for Premium Tax Credits, and make charitable giving after age 70 ½ very tax efficient. At home, many working Americans do not qualify to deduct IRA contributions, so why not contribute to a Roth IRA or Backdoor Roth IRA, since (i) you aren’t giving up a tax deduction in order to do so and (ii) you establish assets growing tax free for the future. 

In this post I discuss why deduct at work, Roth at home can often make sense and I provide examples where Roth 401(k) contributions are likely to be better than traditional 401(k) contributions. 

Conclusion

I believe that for many in the FI community, a retirement savings plan that combines (i) traditional deductible 401(k) contributions during one’s working years and (ii) Roth conversions prior to collecting RMDs is likely to be a better path than simply making all workplace retirement contributions Roth contributions.
