Non-Roth after-tax contribution to a Solo 401k

I have been hearing more and more about non-Roth after-tax contributions as a way to max out Solo 401K contributions. I’m wondering if you have an answer to my lingering questions:


If I make a non-Roth after-tax contribution to my Solo 401-K, can I then immediately make an intra-plan Roth conversion of those funds? (Assume my plan allows it)



Yes just the after-tax solo 401k contributions can be converted (in-plan conversion) to a Roth solo 401k provided the following items are satisfied.


  1. i) The after-tax solo 401k contributions are made into a separate holding account not commingled with the pretax solo 401k contributions, and) ii) the plan allows for in-plan Roth solo 401k conversions.

Lastly, it is best to convert the aft-tax solo 401k funds immediately otherwise the earnings will need to be included in the conversion which will be subject to taxes.


What is the lowest salary I can pay myself (S-corp) and still make the maximum 53K annual 401(k) contribution for 2015? Can I pay myself 53K in salary, make an 18K employee contribution, 13.25K employer contribution (53*.25 = 13.25) and the rest (21.75k) in an employee non-Roth after tax contribution?


It is important to understand that the after tax solo 401k contribution are part of the overall limit. The overall limit for solo 401k plans including solo 401k plans for 2015 is $53,000, or 100% of compensation, whichever is less.

After-tax solo 401k contributions are based on net-income, so because your self-employment entity type is an S-corp, you will need at least $53,000 of w-2 income from self-employment to do the following.

  1. Treat $18,000 as your pretax contribution
  2. Treat the remaining $35,000 as your after-tax solo 401k contribution (make sure it is deposited in its own separate bank account and don’t commingle the funds with your pretax contributions) which you can then turn around and convert to a Roth solo 401k.

Equipment Lease investments for solo 401k Trust


Do you know if a solo 401k can invest in equipment leases?


Yes a solo 401k can invest in equipment leasing. Here is a brief summary of how it works.

The solo 401k is the owner and lender of the equipment. The solo 401k would then lease the equipment to the third-party. Once the lease is up the solo 401k sells the equipment to the lessee or keeps leasing the equipment to the same business or a different business.

The paperwork in connection with the equipment lease would list the solo 401k as the lessor. For example, if the name of John’s Solo 401K is Core Solo 401k Trust, the lessor would read as John Doe, Trustee of Core Solo 401k Trust.

The lease payments would flow back to the solo 401k bank account and so would the proceeds from the sale of the equipment if the solo 401k owner decided to sell the equipment.

Solo 401k Provider Customer Review

With a list of over a hundred solo 401k providers, I narrowed it down and interviewed the top seven companies during my search for a solo 401k provider. After many days of research and conference calls, I decided to go with My Solo 401k Financial because they provide the greatest value especially in the areas of expertise, customer service, and price. Not experienced in setting up retirement accounts, I had a long list of questions during the set up process. I really appreciate that they were always very patient and answered all my questions in a timely manner. As an entrepreneur who will only accept service from the best professionals, I am very happy with my decision and highly recommend My Solo 401k Financial to anyone looking to establish their self-directed retirement plan.

Self-Directed Solo 401k compatibility with Scottrade Advisor

QUESTIONS: I am a CFP and RIA using Scottrade as my custodian. I’d like to establish a self-directed solo 401k for myself, and perhaps do the same for some of my clients. I’d like to incorporate a Scottrade brokerage account into my 401k to facilitate traditional investments as well as checking writing for alternative investments. Is that an option?

ANSWERS: While Scottrade will open a brokerage account for a self-directed solo 401k using Scottrade’s Brokerage Account Application, they will not issue a checkbook. As a result, our clients that want to still use Scottrade will open a brokerage account with Scottrade for trading equities and will also open a local bank account for check-writing, thus resulting in multiple holding accounts under the same self-directed solo 401k.

Self-Directed Solo 401k vs. Self-Directed IRA

The most popular self-directed retirement accounts include the solo 401k and the self-directed IRA. Both pretax and Roth after tax contributions can be made to both. Pretax contributions are tax deductible, and the gains grow tax free until distributions begin. Roth IRAs and Roth solo 401k contributions are not tax deductible when made, but the gains grow tax free.  Following are the similarities and differences between the solo 401k and the self-directed IRA.

The Self-Directed IRA and Solo 401k Similarities

  • To open a self-directed IRA, self-employment income is not required;
  • In order to gain IRA checkbook control over the self-directed IRA funds, a limited liability company (self-directed IRA LLC) must be utilized;
  • The solo 401k allows for checkbook control from the onset;
  • The solo 401k allows for personal loan known as a solo 401k loan;
  • It is prohibited to borrow from your IRA;
  • The Solo 401k may be invested in life insurance;

  • The self-directed IRA participant/owner may not serve as trustee or custodian of her IRA; instead, a trust company or bank institution is required;
  • When distributions commence from the solo 401k a mandatory 20% of federal taxes must be withheld from each distribution and submitted electronically to the IRS by the 15th of the month following the date of each distribution;
  • Rollovers and/or transfers from IRAs or qualified plans (e.g., former employer 401k) to a solo 401k are not reported on Form 5498, but rather on Form 5500-EZ, but only if the air market value of the solo 401k exceeds $250K as of the end of the plan year (generally 12/31);
  • When funds are rolled over or transferred from an IRA or 401k to a self-directed IRA, the amount deposited into the self-directed IRA is reported on Form 5498 by the receiving self-directed IRA custodian by May of the year following the rollover/transfer.
  • Rollovers (provided the 60 day rollover window is satisfied) from an IRA to a Solo 401k or self-directed IRA are reported on lines 15a and 15b of Form 1040;
  • Pre-tax IRA contributions on reported on line 32 of Form 1040;
  • Pre-tax solo 401k contributions are reported on line 28 of Form 1040;
  • Roth solo 401k funds are subject to RMDs;
  • A Roth 401k may be transferred to a Roth IRA (Note that from a planning perspective, it may be advantageous to transfer Roth Solo 401k funds to a Roth IRA before turning age 70 ½ in order to escape the Roth RMD requirement applicable to Roth 401k contributions including Roth Solo 401k contributions and earnings.);
  • Roth IRA funds are not subject to requirement minimum distributions (RMDs);
  • The fair market value (FMV) of assets held in a self-directed IRA is reported on form 5498;

  • At termination, the self-directed IRA is only required to file a form 1099-R.

Exceptions to Early Solo 401k & IRA Distribution Tax Penalties

In addition to being subject to federal and state taxes, most IRA or solo 401k plan distributions are subject to an additional 10% tax.

Usually, the amounts an individual withdraws from a solo 401k or an IRA prior to reaching age 59½ is called ”early” or ”premature” withdrawals. Unless an exception applies, solo 401k participants and IRA holders must pay an additional 10% early withdrawal tax and report the amount to the IRS for any early distributions.

The following chart is a good guide to follow regarding the 10% early penalty when making solo 401k or IRA distributions.

Bad Credit Business Funding Option – Use Your 401k to Start a Business

Are you an aspiring entrepreneur with bad credit? In that case you know well that financing a business with bad credit is no easy task.

Even for a small business owner with good credit, access to financing from traditional sources such as banks, credit unions can be challenging.  According to the Harvard Business School “The State of Small Business Lending” report, the credit market has not returned to pre-crisis levels and has been markedly  more constrained for the small business segment. [1]

For an aspiring business owner with bad credit, the options are even more limited and those lending options that are available are expensive.  For example, an individual with bad credit (typically defined as a credit score below 630) could easily pay 20% or more for a business loan from an alternative lender or finance company.

Other than taking on a loan with credit card-level interest rates, other sources that are typically considered are borrowing money from friends or relatives or perhaps seeking a grant.

Even if these options might be possible, they are less than ideal.  An aspiring entrepreneur will want to avoid the financial pressure of paying back a high-interest loan or the social pressure of being in debt to friends or relatives.  Even if a grant may be possible, the entrepreneur may not have the time to apply for a grant that ultimately may not be awarded.

There is another way to acquire the small business financing you need.  This alternative does not require a credit check nor is it a loan that needs to be paid back.  The strategy entails investing your retirement funds in your own business and is referred to as a rollover as business startup (ROBS) or 401k Business Financing.  If properly structured and executed, you can access all of your retirement funds without paying taxes or penalties.

The high-level steps of a ROBS transaction are as follows:

  • The first step is to form a corporation which must be taxed as a C-corporation.
  • The corporation then adopts a 401k profit sharing plan.
  • As an employee of the corporation, you would participate in the 401k plan and then transfer your retirement funds from your existing retirement account (e.g., former employer 401k, Rollover IRA, etc.)  into the 401k plan.
  • You would then invest your 401k funds in company stock by transferring funds from the 401k to the corporation.
  • The corporation would then be able to use the funds for legitimate business purposes (e.g., buy the assets of an existing business, start a new franchise, etc.).

There are important ongoing compliance requirements (e.g., annual reporting, offering employees the 401k, etc.) as well as specific issues that have to be considered on a case-by-case basis (e.g., whether funds in your existing retirement account are eligible, etc.).

Seller Financing / Seller Carry Back

Q: Where do I book/record seller financing (seller carry back) for my 401k business financing corporation transaction?

A: A seller carry back is not a stock/equity purchase but rather financing that the seller is providing to the ROBS 401k funded C-Corporation.  As such, this transaction is documented between the corporation and the seller as a loan.  It would be reflected on the Corporation’s book as a debt obligation rather than a stock/equity investment.  As such, no stock certificates are issued in connection with seller financing.
