For FAQs Regarding the Solo 401k December Deadline, CLICK HERE.

  • What do I have to do by December?

    • In order to preserve the right to make contributions from your self-employment income for 2018, all you have to do is adopt the 401(k) plan (sign the plan establishment documents) prior to the end of 2018.
    • We make it very easy to do so! All you have to do is sign the solo 401k plan documents before the end of the year.
    • You can set up the bank or brokerage account and make the contribution any time before your tax return deadline including any timely-filed extension in 2019.
  • Do I have to open the bank or brokerage account by December?

    • No.
    • All you need to do is sign the 401(k) plan establishment documents before the end of 2018.
    • This will preserve the right for you to both open the bank/brokerage account and make contributions on or before your tax return deadline including any timely-filed extension in 2019.
    • You can open up the bank/brokerage account next year and we will help you do so. For example, if you want to open a brokerage account such as at Fidelity or Schwab, we will prepare all the paperwork that is needed to open a brokerage account.
  • Do I have to obtain an employer identification number by December?

    • No.
    • All you need to do is sign the 401(k) establishment documents before the end of 2018.
    • This will preserve the right for you to make contributions on or before your tax return deadline including any timely-filed extension in 2019.
    • You can open up the bank/brokerage account next year and we will help you do so. For example, if you want to open a brokerage account such as at Fidelity or Schwab, we will prepare all the paperwork that is needed to open a brokerage account.
  • Is the tax return deadline my personal tax return deadline (e.g. April 15) or my self-employed business tax return deadline in 2019?

    • The applicable tax return deadline is your business tax return deadline since your business is the sponsor of the plan.
    • Of course, if you operate your business as a sole proprietorship or a single member LLC, you will report your self-employment activity on your personal taxes which means your business tax return deadline is the same as your personal tax return deadline.
  • If I adopt the plan in December 2018, how can I make contributions based on income that I earned in January 2018?

    • As is the industry best practice, the solo 401(k) plan is effective as of January 1, 2018 even if you adopt the plan in December 2018.
    • As such, you are able to make contributions for any self-employment income earned and reported for 2018.
  • My CPA/tax advisor is informing me that the employee contribution must be made by December 31, 2018.  Are you sure that I can make this contribution in 2019?

    • This is a common point of confusion as employee contributions for a full-time employer plan such as one that you might have through a day job must be made by the end of the year.
    • The rules are different for solo 401(k) plans and this is clear per IRS Publication 560 which clearly states that both employee and employer contributions can be made any time up until the tax return deadline including any timely filed extension.  For example, please see the table on page 3 of IRS Publication 560.
  • Can I make a Roth conversion for 2018 any time up until my tax return deadline in 2019?

    • No – since converting pretax to Roth funds will result in a taxable event, the deadline to make the conversion effective for 2018 is December 31, 2018.
    • As such you will want to make sure that you set up the plan and accounts as soon as possible to give you as much time as possible to complete the conversion.

The Solo 401k Setup Deadline is December 31, 2018 Unless Congress Changes the Rules

The deadline to establish your Solo 401(k) plan is December 31, 2018. However,  there is a bill (The Family Savings Act- H.R. 6757 that passed the House on September 27,2018  that now needs to be approved by the Senate which would allow employers to adopt a qualified solo 401k plan up to due date of the business tax return.

Unless the above bill is passed by the Senate before year end, for those who are self-employed (i.e., own their own business with no, full-time, W-2 employees), an important deadline is approaching (in less than 60 days) that will afford the self-employed business owner(s) the opportunity to save thousands of dollars in taxable income for tax year 2018.

Open the Solo 401k Plan by December 31, 2018 and Wait to Make Both the Employer and Profit Sharing Contribution in 2019

If you are self-employed and open a solo 401k plan by December 31, 2018, you will be able to wait until next year (2019) to contribute $55,000 plus an additional $6,000 if you turn 50 in 2018 or are already over age 50.  Yes you read this correctly. Specifically, you just need to sign the solo 401k adoption documents to be able to wait until your business tax return due date plus timely filed extensions to make both the profit sharing and employee contributions for tax year 2018.

A Solo 401k Plan is NOT Subject to DOL Rules so Contribution Deadline is More Favorable

A solo 401k is not subject to Department of Labor rules because a solo 401k is for owner-only businesses with no common-law employees. As a result the contribution deadlines are more favorable for a solo 401k. For example, as long as the solo 401k is set up/adopted by December 31, both the salary deferral and employer contributions can be made up until the due date of the self-employed business tax return plus any timely filed extensions. See the following chart found on page 3 of IRS Publication 560- Retirement Plans for Small Businesses.

When looking at the chart, look at the row labeled “Defined Contribution Plan” as a solo 401k plan falls under this umbrella.
