This is how my paycheck is split:
50% after-tax (mega backdoor roth)
10% ESPP
10% pre-tax-401k
3% medical/dental/vision/hsa etc
27% tax
I wanted to frontload my mega backdoor roth. So I set it at 50% deduction from my paycheck. Little did I know that this will drop my paycheck to $0. I will do this for my next 6 paychecks and then stop. This helps me max out the $61k limit. I thought this was interesting and wanted to post on my most fav forum
Wow, it is pretty hard core.
With all uncertainty around mega backdoor Roth I decided to contribute the maximum to my Roth in H1 2022 so I choose 20% for after-tax 401K. In January my net pay was only 31% of the gross.
I don't understand the obsession with $0 vs. just some low amount. I wouldn't want to deal with the almost inevitable error condition when the net went negative for whatever reason.
My wife and I have a contest each year to see who can get their paycheck lower at the start of the year.
To make this a little bit more actionable, it’s really a tactic to get your money in the market earlier. Rather than having your annual contribution spread over the entire year, having them in the market at the start of the year on average to grow over the period that they’re in the market.
Of course, you do need to check the matching provisions of your 401(k) to verify that you received the entire match if you make out with a deposit at the start of the year as opposed to level contributions.
I choose to front load the pre-tax 401K first. In the case that I am laid off in 2022 and join some other employer, they may not have the mega backdoor Roth. But, I still could contribute to pre-tax 401K at the new employer and getting the match.
KlangFool
I am missing something since your calculations are flawless. Say, your annual salary was $82K and you saved 50% towards pre-tax 401k for 6 months. You would've front loaded the entire annual pre-tax limit of 20.5K in H1 2022 ($82k/6months*50%). If you changed employers in H2 2022, you would not be able to get an employer match with a new employer, right? Unless you front loaded a smaller amount that still lets you spread out contributions to get the typical employer match through the year (say, 4%).
OTOH, if you front load the 50% towards a mega backdoor, you get to contribute $20.5K with both employers (assuming the new employer offers it as well)

Exactly. For the longest time, I was in the DCA camp. This forum converted me:
Lump sum investing will always carry a higher expected return, because it immediately moves your funds from asset classes with lower expected returns to ones with higher expected returns. Note that higher expected returns do not guarantee that your actual returns will be higher. According to an investopedia article,[5] studies indicate that lump sum investing has produced higher returns 66% of the time.

Most payroll systems will deal with the error with priority ordering, so that obligations (taxes, insurance, etc.) are met first.
We still don't obsess with zero. We don't being home enough to pay the bills when we are front loading, but we do bring home a couple of hundred dollars a month. This partly because we are pretty sure that the 401k is a higher priory than the ESPP, but due to the limit on ESPP, there isn't much room to make up for any shortfall.

Alto Astral,
<<If you changed employers in H2 2022, you would not be able to get an employer match with a new employer, right? >>
A) You can contribute another 20.5K with the new employer. It just that you would have to pay tax on this 20.5K when you file your taxes. So, you probably only contribute enough to receive employer match for the new employer.
B) My current employer match contribution from Trad 401K, Roth 401K, and after-tax 401K.
<<assuming the new employer offers it as well)>>
C) Most employers in my area does not offer mega backdoor Roth. Or, it is very limited. For example, only up to 12% of the gross pay. My current employer is the exception.
Are you sure that you are not subjected to the HCE limitation for Mega Backdoor Roth contribution? Please note that this limit exists even if you have a safe harbor 401K plan.
I know that I don't because I only work for my current employer for half year in 2021.

Yeah I do the same! Feels like I am fortunate to have an employer that provides this automatic after-tax 401K Roth-In-Place conversion in Fidelity! For living expenses, I end up liquidating my RSUs and that forces me to also divest from the company stock!

Alto Astral,
Please read the second bullet of your source.
<<Received compensation from the business of more than $130,000 if the preceding year is 2021 >>
If you earn more than 130K from this employer in 2021, you are most likely HCE.
I did that for a few months as I was leaving my last job, but if I didn’t withhold enough for required taxes, the tax-deferred contribution wouldn’t be withheld (for me it was all or nothing if you don’t have enough left in the paycheck to make the fixed dollar contribution).

I am assuming that its needs to be the combination of $130K AND top 20% as below. I will confirm with HR and 401k provider.
Received compensation from the business of more than $130,000 if the preceding year is 2021 (and more than $135,000 if the year is 2022), and if the employer so chooses, was in the top 20% of employees when ranked by compensation

Yes. I double-checked and employee taxes include OASDI, Medicare, Federal Withholding, State Tax. It also deducted the tax-deferred contribution correctly. I triple-checked the total taxes against what was deducted in last month's paycheck (when the net pay was not $0) and its almost the same amount.
There is a reddit thread where users comment that companies such as FedEx, GM, Dow Chemicals, UTC, Cisco etc. offer it as well
I've also read on this forum that some state/federal government employers also allow this
The TSP definitely doesn't allow this. Perhaps the secondary 401k that some agencies offer, like the ncua or FDIC, do.
True. In fact many plans are not very clear about this either. For example, my wife's plan allows a "Savings Account" where you can make after-tax contributions either via payroll contributions or lumpsum. It then lets her do an in-plan Roth conversion twice a year. We did not realize for many years that this was in fact a mega backdoor. Oh well, better late than never. We did a lumpsum last year towards it.

How do you manage living expenses? Save up late in the prior year?
At the OPs salary level they probably have large taxable accounts built up they can coast on.
Yeah, but presumably people don't want to sell investments to live off of if they don't have to during the accumulation phase.
maybe/ maybe not... if you don't have massive capital gains in taxable, you can view this as simply "transforming" existing accumulated assets from taxable accounts to Roth accounts.... would you rather have a dollar in taxable or a dollar in roth?
I think that this is especially likely given that MBD has just popped up in the last ~5 years or so.... so there are a lot of middle aged/ upper-middle class earners with a sizeable taxable accounts looking for shelter.
I did my first MBD about 15 years ago. Perhaps you meant it really gained momentum in the past 5 years or so.

Could be. Sadly, 10 years ago, the same employer stopped offering it.
Back then, our choices were traditional or after-tax 401k. Then our choices became traditional or Roth 401k. I miss having the older option. I had gotten my in-service withdrawals set up nicely by the time they stopped offering the whole process. Another thing that came about with the plan change is that the plan became a Safe Harbor plan, so we no longer needed to worry about HCEs.
Could getting a $0 paycheck for 6 months cause an issue when I apply for a mortgage later this year? I plan to put 20% down and have it in a HYSA. I have other money in taxables, i-bonds etc but not cash.

I've done something similar a few times in the past when I worked part of the year as a consultant and then later got a full-time job and wanted to fully fund my 401(k) before the end of the year.

I've had zero net pay for several months the last 3 years.
I just got access to a Roth 457b in addition to my 403b.
Maxing the 403b brings my taxable income down to the top of the 12% bracket, so I load up the 457b with Roth.
My income is not so high that I need a backdoor Roth.
The accounting office called me the first time to ensure that I really meant to get zero net pay, to which I of course said yes
I'm doing something similar at my new job, which has access to a 401k (trad or Roth) as well as a 457b (trad only). You can contribute up to 75% of your salary to the 401k, but 100% to the 457, and the contribution limits of $20,500 are for each separately not combined. So I'm doing ~50% into a Roth 401k w/ matching, and ~40% into the 457; the rest goes to taxes and pays my health insurance premiums. It's been "fun" trying to calculate how much the taxes on the Roth contribution will be because that changes the amount that goes into the 457 which of course reduces the taxes...Oh yeah and I'm hourly, not salaried, so my gross income each paycheck is slightly different.
I have some cash from a previous house sale which I'm using to pay my expenses for the time being. When I use that up I plan to crank down my contributions, but I figure for the time being I'm basically converting taxable money to tax-free and tax-deferred money for later.

Your paystubs still show your gross pay, don’t they? Isn’t that what they’d care about?

I agree with you about lump sum vs. DCA, but I don't think that's really what you're doing here. You're getting $0 in net pay, and as you say you're paying expenses from either saved money (that could have been invested earlier) or from your spouse's pay (that could be invested instead). So I agree that you're front-loading your MBD Roth, but possibly at the expense of delaying other investments.
In any case, congrats on being able to do this. I'm severely limited because of being an HCE, which my company defines as any employee who made over $135k gross in 2021. Luckily, the limit is high enough I can still max the pre-tax, but I can only get a few $k into after-tax 401k for the MBD. If I try to front-load my after-tax, I risk not reaching the pre-tax maximum at the end of the year.

+1. I frontload both my pre-tax 401(k) and my Mega Backdoor Roth over the first 7 months of the year. But I understand that it means effectively backloading my taxable investments (and taxes).
There may be a slight advantage (in an up year, otherwise it'd be a slight disadvantage) due to frontloading the company match, but I'm not counting on that to make me rich
At the end of the year, assuming I keep my job all year, I'll have saved exactly the same amount of money.

How does your company enforce the contribution to the MBD for HCEs? Is it automatic or something you voluntarily calculate?

Isn't there the long term advantage though? The MBD growth will be tax free on account of being Roth. OTOH, the taxable investment will be taxed depending on when you sell. You could keep the taxable invested until you retire and then still pull off a 0% income tax, if your expenses permit it. In that case it would be exactly the same inside a MBD or outside.

It's not a question of where the money is going, but when. I will invest money in both MBD and taxable this year. Since I front-load both my 401(k) and my MBD, I have to backload my taxable, but that doesn't change the amounts.
But I was comparing doing pre-tax 401(k) (with match) first, or MBD first.
ok, I'm not getting this.
Coulda been the Whiskey, might have been the Gin, coulda been the 3 or 4 beers I don't know...
Maybe someone can explain the mechanics of this?
Are you a W2 employee?
Assume your employer 401K has a Roth option?
Your 401K plan must have in-service withdrawals allowed?
So do you payroll deduct max the plan allows to Roth 401K, then you in-service withdrawal (roll) into your normal backdoor Roth account immediately?
For my Solo 401K at E*Trade I do have Roth authorized, not sure about the in-service withdrawal but I can check.
Appreciate someone setting me straight on this as I'd like to hit the max but my 20% limit on earnings won't get me there. Thank you.

jello_nailer,
No, this is not Roth 401K. This is after-tax 401K.
There are 3 kinds of 401K accounts: Trad 401K, Roth 401K, and after-tax 401K.
For after-tax 401K, some plan offer
A) In-service Roth conversion to Roth 401K.
And/or
B) In-service withdrawal to Trad IRA and Roth IRA.

My after-tax allows for Roth conversions but NOT in-service withdrawals. While I can convert it into a mega backdoor roth, I cannot move it out so long as I am employed with this company.

jello_nailer,
But, you may not need this from your Solo 401K because you are the employer.
You have
A) Employee Roth 401K, Employee Trad 401K
And
B) Employer Trad 401K.
(A) is limited to 20.5K. (B) is not.
You should start a new topic and ask about your specific situation.

Luckily, the limit is high enough I can still max the pre-tax, but I can only get a few $k into after-tax 401k for the MBD.

Are you also in the top 20% of all employees in your company? My gross is above that limit as well but its fairly common (say, over 50% folks in my company)
They enforce it by limiting total 401k contributions to 16% of salary for HCEs. $135k*0.16 = $21.6k. So somebody just over the limit can max the pre-tax, but they won't be able to contribute much beyond that. Someone making $305k+ could contribute $48.8k under that system in theory, but they would probably get a good chunk refunded if the plan failed testing.
As for being top 20%, I suspect I'm not but I've never seen stats published. My understanding is that companies CAN use the top 20% thing as a threshold, but most(?) don't. I imagine places like doctor's offices and tech companies use it more often since they're top-heavy. If you are classified as an HCE you should have been notified, but you can always reach out to HR and ask if you're concerned.

Also look to see if your 401k does anywhere reference "Safe Harbor". If someone has a safe harbor plan, the HCE restrictions don't apply.

I see what you mean here now. If you DCA'd the 401k through the year, you would've got the company match in every paycheck. With front loading, now you need to wait till the end of the year when the company does the "true up".

It's not a question of where the money is going, but when. I will invest money in both MBD and taxable this year. Since I front-load both my 401(k) and my MBD, I have to backload my taxable, but that doesn't change the amounts.
But I was comparing doing pre-tax 401(k) (with match) first, or MBD first.
Ah, got it.
There may be a slight advantage (in an up year, otherwise it'd be a slight disadvantage) due to frontloading the company match, but I'm not counting on that to make me rich

No, my company matches contributions as you make them - it’s not function of my salary (50% of contributions). So I will have gotten the full match whenever I max out the 401(k). This year that should happen by end of March.
