Are there limits on frequency of withdrawal from Roth 401K?
Back in the late 80's I had a co-worked do exactly this. In those days you could only do things quarterly: change the percentage, change the investment mix, make a withdrawal.. There were no Roth 401K accounts, but contributions could be pre-tax or post-tax. Long term employees were matched 100% up to 8%, newer employees were only matched 50% up to 8% (resulting in 4% match). Every quarter this employee put in 8%, and then pulled out the previous quarters contribution. The company match continued to grow.  Was it smart? He still ended up with 8% going into the 401K. In those pre-Enron days the law allowed companies to limit the company match to 100% company stock which meant that employees retirement was at risk. Of course by the early 2000's the stock that was purchased for $6 a share was worth $80 a share... Now what about the IRS: Since I make designated Roth contributions from after-tax income, can I make tax-free withdrawals from my designated Roth account at any   time? No, the same restrictions on withdrawals that apply to pre-tax   elective contributions also apply to designated Roth contributions. If   your plan permits distributions from accounts because of hardship, you   may choose to receive a hardship distribution from your designated   Roth account. The hardship distribution will consist of a pro-rata   share of earnings and basis and the earnings portion will be included   in gross income unless you have had the designated Roth account for 5   years and are either disabled or over age 59 ½. Regarding getting just contributions: What happens if I take a distribution from my designated Roth account before the end of the 5-taxable-year period? If you take a distribution from your designated Roth account before   the end of the 5-taxable-year period, it is a nonqualified   distribution. You must include the earnings portion of the   nonqualified distribution in gross income. However, the basis (or   contributions) portion of the nonqualified distribution is not   included in gross income. The basis portion of the distribution is   determined by multiplying the amount of the nonqualified distribution   by the ratio of designated Roth contributions to the total designated   Roth account balance. For example, if a nonqualified distribution of   $5,000 is made from your designated Roth account when the account   consists of $9,400 of designated Roth contributions and $600 of   earnings, the distribution consists of $4,700 of designated Roth   contributions (that are not includible in your gross income) and $300   of earnings (that are includible in your gross income). See Q&As regarding Rollovers of Designated Roth Contributions, for   additional rules for rolling over both qualified and nonqualified   distributions from designated Roth accounts.
On the statement it now tracks how much is contributed to the account   pre and post tax. This is the key. Your withdrawals will be proportional. Assuming you have contributed 90% in regular contributions (pre-tax) and 10% in Roth (post tax), when you withdraw $1000, it will be $900 from the regular (taxed fully) and $100 from the Roth (not taxed, assuming its a qualified distribution). Earnings attributed proportionally to the contributions. I agree with you that it is not the best option, and would also prefer separate accounts, but with 401k - the account is per employee. Instead of doing 401k Roth/Non-Roth consider switching to Regular 401k and Roth IRA - then you can separate the funds easily as you wish. Deposits are contributions. You deposit say, $5000, and over time you have $6000.  The $5000 can be withdrawn any time with no issue. It's tracked via form 8606.  With this in mind, I wrote an article The Roth Emergency Fund, suggesting that since one can withdraw deposits with no issue, the Roth can be used to hold emergency money. The point is to provide for yourself in retirement, so it makes sense that these withdrawals would be penalized. Tax deferred accounts are usually created for a specific cause. Using them outside of the scope of that cause triggers penalties. You mentioned 401(k) and IRA that have age limitations because they're geared towards retirement. In the US, here are other types, and if you intend to spend money in the related areas, they may be worth considering. Otherwise, you'll hit penalties as well. Examples: HSA - Health Savings Account allows saving pre-tax contributions and gains towards medical expenses. You must have a high deductible health plan to be eligible. Can be used as IRA once retired. 529 plans - allow saving pre-tax gains (and in some states pre-tax contributions) for education expenses for you or a beneficiary. If a beneficiary - contributions are considered a gift. There's a tax benefit in long term investing in a regular taxable brokerage accounts - long term capital gains are taxed at a preferable (lower) rate than short term or ordinary income. The difference may be significant. Long term = 1+ year holding. The condition here is holding an investment for more than a year, and there's no penalty for not satisfying it but there's a reward (lower rates) if you do. Part of the difficulty in this sort of planning is that you are also betting on future tax rates and comparing them with current taxes.  If you are in a low tax bracket now, but expect to be in a higher one when you take the money out, it is better to pay the taxes now.  If you are in a high tax bracket now, but expect to be in a lower one when you retire/take the money out, then it is better to defer the taxes until then.  If you think that future sessions of Congress will decide to tax withdrawals from Roth accounts, then you should contribute to traditional accounts.  The problem is that you don't know with certainty what the future will bring. So you have to make educated guesses about what might happen, and what you can do now to protect yourself from it. Ideally, plan so that even if the bad things happen, you will be reasonably comfortable. There are 3 options (option 2 may not be available to you) When you invest 18,000 in a Traditional 401k, you don't pay taxes on the 18k the year you invest, but you pay taxes as you withdraw.  There's a Required Minimum Distribution required after age 70.  If your income is low enough, you won't pay taxes on your withdrawals.  Otherwise, you pay as if it is income.  However, you don't pay payroll tax (Social Security / Medicare) on the withdrawals.  You pay no tax until you withdraw. When you invest 18,000 in a Roth 401k, you pay income tax on the 18,000 in the year it's invested, but you pay nothing after that. When you invest 18,000 in a taxable investment account, you pay income tax on that 18,000 in the year it's invested, you pay tax on dividends (even if they're re-invested), and then you pay capital gains tax when you withdraw. But remember, tax rules and tax rates are only good so long as Congress doesn't change the applicable laws. Your math is fine, except employers might not permit the withdrawal. You'd have to go back to their rules or contact HR to understand the withdrawals permitted. Mostly true. Very few plans allow for in-service withdrawal options. In most cases plans that do, only allow pure after tax sources to be withdrawn prior to age 59.5. The other case would be if you had rolled money from another k plan into your current plan. In almost all plans that money is always accessible.  Otherwise you generally will have to wait to request a distribution until you turn 59.5 years of age. Another option if it is available is a Roth 401k.  It is similar to a Roth IRA in that you pay taxes up front, but the withdrawals are tax free. No, you cannot. If you withdraw everything from all your Roth IRA's and end up with less than the total basis - you can deduct the difference on your schedule A (at the time of the last withdrawal) as an itemized deduction (as misc. deductions with 2% AGI cap). Regular IRA's are pre-tax, you cannot deduct anything from them. You may withdraw your contributions to a Roth IRA at any time for any reason without penalty.   Any gains you withdraw may be subject to tax or penalties though, but there is a $10,000 exclusion (from the 10% penalty, not the taxes) for a first time home purchase. "Yes you can do the withdraw if you turned 55 during the year you separated from service. http://www.401khelpcenter.com/401k_education/Early_Dist_Options.html#.VdMrqPlVhBc Leaving Your Job On or After Age 55 The age 59½ distribution rule says any 401k participant may begin to withdraw money from his or her plan after reaching the age of 59½ without having to pay a 10 percent early withdrawal penalty. There is an exception to that rule, however, which allows an employee who retires, quits or is fired at age 55 to withdraw without penalty from their 401k (the ""rule of 55""). There are three key points early retirees need to know. First, this exception applies if you leave your job at any time during the calendar year in which you turn 55, or later, according to IRS Publication 575. Second, if you still have money in the plan of a former employer and assuming you weren't at least age 55 when you left that employer, you'll have to wait until age 59½ to start taking withdrawals without penalty. Better yet, get any old 401k's rolled into your current 401k before you retire from your current job so that you will have access to these funds penalty free. Third, this exception only applies to funds withdrawn from a 401k. IRAs operate until different rules, so if you retire and roll money into an IRA from your 401k before age 59½, you will lose this exception on those dollars." If you do not need the money in the 401k right away and are interested in avoiding penalties on the amounts accumulated, roll over the 401k monies into a Roth IRA (your contributions and growth thereof) and a Traditional IRA (company match a d growth thereof). You can choose to take out money from the Traditional IRA not as a lump sum (penalties in addition to lots of income tax in the year of taking the distribution) but as series of equal payments over your life expectancy (no penalty but US income tax is still due each year). Be aware that he who rides a tiger cannot dismount: if you opt for this method, you must take a distribution every year whether you need the money or not, and the amount of the distribution must match what the IRS wants you to take exactly; excess withdrawals lead to penalties etc.  Publication 590 says Annuity. You can receive distributions from your traditional IRA that are part of a series of substantially equal payments over your life (or your life expectancy), or over the lives (or the joint life expectancies) of you and your beneficiary, without having to pay the 10% additional tax, even if you receive such distributions before you are age 59.5. You must use an IRS-approved distribution method and you must take at least one distribution annually for this exception to apply. The “required minimum distribution method,” when used for this purpose, results in the exact amount required to be distributed, not the minimum amount. Be aware that, depending on your country of residence/citizenship, you may be required to close all foreign accounts within x months of return, and if so, this stratagem will not work. You may withdraw penalty-free from a 401(k) if you separate from service at 55 or later. This may make the rolling to any IRA not a good idea. You can withdraw penalty free if you are disabled. You can withdraw penalty free if you take the withdrawal using a process called Section 72t which basically means a steady withdrawal for either 5 years or until age 59-1/2 whichever is second.  Aside from these exceptions, the concept is to be allowed to take withdrawals after 59-1/2, but you must start to take withdrawals starting at 70-1/2. These are called RMDs (required minimum distributions) and represent a small fraction of the account, 1/27.4 at 70, 1/18.7 at 80, 1/11.4 at 90.  Each year, you take a minimum of this fraction of the account value and pay the tax. If you had a million dollars, your first withdrawal would be $36,496, you'd be in the 15% marginal rate with this income.  In general, it's always a good idea to be aware of your marginal tax rate. For example, a married filing joint couple would be in the 15% bracket up to a taxable $74,900 in 2015. At withdrawal time, and as the year moves along, if they are on track to have a taxable $64,900 (for example), it would be wise to take the extra $10,000, either as a withdrawal to put aside for the next year, or as a Roth conversion. This way, as the RMDs increase, they have a reduced chance to push the couple to the next tax bracket. "Welcome to the 'what should otherwise be a simple choice turns into a huge analysis' debate. If the choice were actually simple, we've have one 'golden answer' here and close others as duplicate. But, new questions continue to bring up different scenarios that impact the choice.  4 years ago, I wrote an article in which I discussed The Density of Your IRA. In that article, I acknowledge that, with no other tax favored savings, you can pack more value into the Roth.  In hindsight, I failed to add some key points. First, let's go back to what I'd describe as my main thesis: A retired couple hits the top of the 15% bracket with an income of   $96,700. (I include just the standard deduction and exemptions.) The   tax on this gross sum is $10,452.50 for an 'average' rate of 10.8%. The tax, paid or avoided, upon deposit, is one's marginal rate. But,   at retirement, the withdrawals first go through the zero bracket (i.e.   the STD deduction and exemptions), then 10%, then 15%. The above is the simplest snapshot. I am retired, and our return this year included Sch A, itemized deductions. Property tax, mort interest, insurance, donations added up fast, and from a gross income (IRA withdrawal) well into the 25% bracket, the effective/average rate was reported as 7.3%. If we had saved in Roth accounts, it would have been subject to 25%.  I'd suggest that it's this phenomenon, the ""save at marginal 25%, but withdraw at average sub-11%"" effect that account for much of the resulting tax savings that the IRA provides.  The way you are asking this, you've been focusing on one aspect, I believe. The 'density' issue. That assumes the investor has no 401(k) option. If I were building a spreadsheet to address this, I'd be sure to consider the fact that in a taxable account, long term gains are taxed at 15% for higher earners (I take the liberty to ignore  that wealthier taxpayers will pay a maximum 20% tax on long-term capital gains. This higher rate applies when your adjusted gross income falls into the top 39.6% tax bracket.) And those in the 10 or 15% bracket pay 0%. With median household income at $56K in 2016, and the 15% bracket top at $76K, this suggests that most people (gov data shows $75K is 80th percentile) have an effective unlimited Roth. So long as they invest in a way that avoids short term gains, they can rebalance often enough to realize LT gains and pay zero tax.  It's likely the $80K+ earner does have access to a 401(k) or other higher deposit account. If they don't, I'd still favor pretax IRAs, with $11K for the couple still 10% or so of their earnings. It would be a shame to lose that zero bracket of that first $20K withdrawal at retirement. Again working backwards, the $78K withdrawal would take nearly $2M in pretax savings to generate. All in today's dollars." The primary advantage of an IRA or 401k is you get taxed effectively one time on the money (when you contribute for Roth, or when you withdraw for Traditional), whereas you get taxed effectively multiple times on some of the money in a taxable account (on all the money when you contribute, plus on the earnings part when you withdraw). Of course, you have to be able to withdraw without penalty for it to be optimally advantageous. And you said you want to retire decades early, so that is probably not retirement age. However, withdrawing early does not necessarily mean you have a penalty. For example: you can withdraw contributions to a Roth IRA at any time without tax or penalty; Roth 401k can be rolled over into Roth IRA; other types of accounts can be converted to Roth IRA and the principal of the conversion can be withdrawn after 5 years without penalty.
