How much total salary to allocate to defer $17,500 to 401(k)?
You're on the right track, and yes, that small difference is subject to income taxes. Do you use a payroll service? I do the same thing and use my payroll software to tweak the salary until the paycheck is just a few dollars every month (we run payroll once a month), with the rest going to the 401(k) and payroll taxes. So we're rounding up just a bit just so there's an actual paycheck with a positive number, and a bit does get withheld for fed/state income tax.  Also keep in mind you can make a company match. If your plan is a solo 401(k) with just you and your wife as the sole employees, consider the 25% match for both of you. The match is not subject to payroll taxes because it is a company expense.

While tax deferral is a nice feature, the 401k is not the Holy Grail.  I've seen plenty of 401k's where the investment options are horrible: sub-par performance, high fees, limited options.   That's great that you've maxed out your Roth IRA.  I commend you for that.   As long as the investment options in your 401k are good, then I would stick with it. My observations is that this seems like hardly enough to kill   inflation. Is he right? Or are there better ways to invest? The tax deferral part of the equation isn't what dominates regarding whether your 401k beats 30 years of inflation; it is the return on investment.  If your 401k account tanks due to a prolonged market crash just as you retire, then you might have been better off stashing the money in the bank.  Remember, 401k money at now + 30 years is not a guaranteed return (though many speak as though it were).  There is also the question as to whether fees will eat up some of your return and whether the funds your 401k invests in are good ones. I'm uneasy with the autopilot nature of the typical 401k non-strategy; it's too much the standard thing to do in the U.S., it's too unconscious, and strikes me as Ponzi-like.  It has been a winning strategy for some already, sure, and maybe it will work for the next 30-100 years or more.  I just don't know.  There are also changes in policy or other unknowns that 30 years will bring, so it takes faith I don't have to lock away a large chunk of my savings in something I can't touch without hassle and penalty until then. For that reason, I have contributed very little to my 403b previously, contribute nothing now (though employer does, automatically.  I have no match.) and have built up a sizable cash savings, some of which may be used to start a business or buy a house with a small or no mortgage (thereby guaranteeing at least not paying mortgage interest).  I am open to changing my mind about all this, but am glad I've been able to at least save a chunk to give me some options that I can exercise in the next 5-10 years if I want, instead of having to wait 25 or more. You're correct about the 401(k). Your employer's contributions don't count toward the $18k limit. You're incorrect about the IRAs though. You can contribute a maximum of $5500 total across IRA and Roth IRA, not $5500 to each. There are also limits once you reach higher levels of income. from IRS.gov: Retirement Topics - IRA Contribution Limits: For 2015, 2016, and 2017, your total contributions to all of your traditional and Roth IRAs cannot be more than: The range is fine. It's ~ 1-2X your annual income.  First, and foremost - your comment on the 401(k), not knowing the fees, is a red flag to me. The difference between low cost options (say sub .25%) and the high fees (over .75%) has a huge impact to your long term savings, and on the advice I'd give regarding maximizing the deposits.  At 26, you and your wife have about 20% of your income as savings. This is on the low side, in my opinion, but others suggest a year's salary by age 35 which implies you're not too far behind.  Given your income, you are most likely in the 25% federal bracket. I'd like you to research your 401(k) expenses, and if they are reasonable, maximise the deposit. If your wife has no 401(k) at work, she can deposit to an IRA, pre-tax.  It's wise to keep 6 months of expenses as liquid cash (or short term CDs) as an emergency fund in case of such things as a job layoff. They say to expect a month of job hunting for each $10K you make, so having even a year to find a new job isn't unheard of.  One thing to consider is to simply kill the mortgage. Before suggesting this, I'd ask what your risk tolerance is? If you took $100K and put it right into the S&P, would you worry every time you heard the market was down today? Or would you happily leave it there for the next 40 years? If you prefer safety, or at least less risk, paying off the mortgage will free up the monthly payment, and let you dollar cost average into the new investments over time. You'll have the experience of seeing your money grow and learn to withstand the volatility.  The car loan is a low rate, if you prefer to keep the mortgage for now, paying the car loan is still a guaranteed 3%, vs the near 0% the bank will give you. "You are legally able to contribute more than 4% to your 401(k) (unless you've hit the actual limit).  There is no reason you need to pull out your ""extra"" contribution.  So basically they just want their $27.50 back. So offer (via email or writing) to send them a check.  You obviously don't work there any more, so if they insist it comes from your IRA or are not willing to accept a check, tell them to @%#&* off (OK, not really, that would be unprofessional, but that's the general idea).  They overpaid you by $27.50, and you are legally bound to return the extra pay, but not to put up with their BS.  Tell them you've offered to pay, and if they don't want to accept a check, they can sue you for it to try to get it in the form they prefer (which they won't do, and even if they did, at most the judge would just tell you to write a check - which you offered from the outset, so they'd probably owe your legal fees)." Please note that if you are self employed, then the profit sharing limit for both the SEP and Solo 401(k) is 20% of compensation, not 25%. There is no need for a SEP-IRA in this case.  In addition to the 401(k) at work, you have a solo-401(k) for your consulting business.  You can contribute $18,000 on the employee side across the two 401(k) plans however you wish.  You can also contribute profit sharing up to 20% of compensation in your solo 401(k) plan.  However, the profit sharing limit aggregates across all plans for your consulting business.  If you max that out in your solo 401(k), then you cannot contribute to the SEP IRA. In other words, the solo 401(k) dominates the SEP IRA in terms of contributions and shares a limit on the profit-sharing contribution.  If you have a solo 401(k), there is never a reason to have a SEP for the same company. Example reference: Can I Contribute to a solo 401(k) and SEP for the same company? "There are two types of 401(k) contributions: ""elective contributions,"" which are the part put in by the employee and ""nonelective contributions,"" which are the part put in by the company.  Elective contributions are summed across all the plans she is contributing to.  So she can contribute $18,000 minus whatever she put in her 403(b). Additionally she can contribute 20% of the net profit of the company (before the elective contributions) as nonelective contributions (these contributions must be designated as such). You will notice that the IRS document says 25%, but that's what you can do if her business is incorporated.  For a sole proprietorship, nonelective contributions  ends up being limited at 20% of profit. Additionally, the sum of these two and her contribution to her 403(b) cannot exceed $53,000. Example: line 31 of her schedule C is $30,000 and she has contributed $10,000 to her 403(b). Maximum contribution to her solo 401(k) is ($18,000 - $10,000) + 0.2 * $30,000 = $14,000 Her total contributions for the year are $10,000 from her 403(b) plus $14,000 in her solo 401(k).  This is less than $53,000 so this limit does not bind.  If she made a ton of 1099 money, her contribution maximum would follow the above until it hit $53,000 and then it would stop there. The IRS describes this in detail in Publication 560, which also has a worksheet for figuring out your maximum explicitly.  It's unpleasant reading and the worksheets are painful, but if you do it right, it will end up being as I just described it.  Using the language of that publication, hers is a ""qualified plan"" of the ""defined contribution"" variety." Probably the biggest tax-deferment available to US workers is through employee-sponsored investment plans like the 401k.  If you meet the income limits, you could also use a Traditional IRA if you do not have a 401k at work.  But keep in mind that you are really just deferring taxes here.  The US Government will eventually get their due. :) One way which you may find interesting is by using 529 plans, or other college investment plans, to save for your child's (or your) college expenses.  Generally, contributions up to a certain amount are deductible on your state taxes, and are exempt from Federal and State taxes when used for qualifying education expenses.  The state deduction can lower your taxes and help you save for college for your children, if that is a desire of yours. One possible downside is contribution limit.  The 401K contribution limit is $18,000 for 2016, which is more than three times the limit for IRA contributions ($5,500). Another option to a human advisor is FutureAdvisor, a web service that (if it supports your 401k plan) gives personalized algorithmic advice on what you should hold in your 401(k) and other retirement accounts.  If it doesn't support your 401(k) plan just yet you can sign up to be emailed when your plan is added.  [Disclosure: I work here, but I believe in the product and it's designed to solve this exact problem so I'm mentioning it here]  Note from JoeTaxpayer - bolu's disclosure is much appreciated. The fee is $39/yr, with a free trial. Consider that a commissions based advisor won't even take on a $10K level account, and at $100K, you'd be hard pressed to gain by more than his 1% fee. So while I've not dug deeper into this site, a rules-based methodology is likely to be worth the cost if over time it gains you even a fraction of a percent compared to what you'd have done blindly. On re-reading the question, I see that you're self-employed, decent income, but only have an IRA. Since the crux of the question appears to be related to your wanting to put aside more money, I suggest you open a Solo 401(k) account. The current year limit is $17,000, and you can still have an IRA if you wish. In addition to the normal limits, A Solo 401(k) allows you to contribute up to 20% of net profits (sole proprietor) or 50% of salary (if a corporation), up to $49,000. Note that the fees for 401(k) accounts are higher than with the IRA. See 401(k)s for small business. If you were looking to maximize your ability to save in a qualified plan, why not setup a 401K plan in Company A and keep the SEP in B? Setup the 401K in A such that any employee can contribute 100% of their salary.  Then take a salary for around 19K/year (assuming under age 50), so you can contribute and have enough to cover SS taxes.   Then continue to move dividends to Company A, and continue the SEP in B.  This way if you are below age 50, you can contribute 54K (SEP limit) + 18K (IRA limit) + 5500 (ROTH income dependent) to a qualified plan. "You're getting great wisdom and options. Establishing your actionable path will require the details that only you know, such as how much is actually in each paycheck (and how much tax is withheld), how much do you spend each month (and yearly expenses too), how much spending can you actually cut or replace, how comfortable are you with considering (or not considering) unexpected/emergency spending. You mentioned you were cash-poor, but only you know what your current account balances are, which will affect your actions and priorities. Btw, interestingly, your ""increase 401k contributions by 2% each year"" will need to end before hitting the $18K contribution limit. I took some time and added the details you posted into a cash-flow program to see your scenario over the next few years. There isn't a ""401k loan"" activity in this program yet, so I build the scenario from other simple activities. You seem financially minded enough to continue modeling on your own. I'm posting the more difficult one for you (borrow from 401k), but you'll have to input your actual balances, paycheck and spending. My spending assumptions must be low, and I entered $70K as ""take-home,"" so the model looks like you've got lots of cash. If you choose to play with it, then consider modeling some other scenarios from the advice in the other posts. Here's the ""Borrow $6500 from 401k"" scenario model at Whatll.Be: https://whatll.be/d1x1ndp26i/2 To me, it's all about trying the scenarios and see which one seems to work with all of the details. The trick is knowing what scenarios to try, and how to model them. Full disclosure: I needed to do similar planning, so I wrote Whatll.Be and I now share it with other people. It's in beta, so I'm testing it with scenarios like yours. (Notice most of the extra activity occurs on 2018-Jan-01)" First a few comments: Other benefits: It may not be possible for everybody to max out the 401K on an income of 100K. It would depend on family size, other income, other expenses, other debts...
