Solo K Form 5500 Tax Filing and Five-Point Compliance Checklist

Solo 401(k)s have become a popular retirement plan option for self-employed persons. Unfortunately, many plans are not properly maintained and are at the risk of significant penalty and/or plan termination. If you have a Solo 401(k), you need to ensure that the 401(k) is being properly maintained. Here’s a quick checklist to make sure your plan is on track:

1. Does your Solo 401(k) need to file a Form 5500-EZ?

There are two primary situations where you are required to file a Form 5500 for your Solo 401(k).

  1. If your Solo 401(k) has more than $250,000 in assets, and
  2. If the Solo 401(k) plan is terminated (regardless of total asset amount).

If either of these instances occur, then the Solo 401(k) must file a Form 5500 to the IRS annually. Form 5500 is due by July 31st of each year for the prior year’s plan activity. Solo 401(k)s can file what is known as a 5500-EZ. The 5500-EZ is a shortened version of the standard Form 5500. Unfortunately, the Form 5500-EZ cannot be filed electronically and must be filed by mail. Solo 401(k) owners have the option of filing a Form 5500-SF online through the DOL. The online filing is preferred as it can immediately be filed and tracked by the plan owner. In fact, if you qualify to file a 5500-EZ, the IRS and DOL allow you file the Form 5500-SF online, but you can skip certain questions so that you only end up answering what is on the shorter Form 5500-EZ. We regularly file Form 5500-EZs and 5500-SFs for Solo K clients in the law firm for only $250.

2. Is the plan up-to-date?

The IRS requires all 401(k) plans, including Solo 401(k)s, to be amended at least once every six years. If you’ve had your plan over six years and you’ve never restated the plan or adopted amendments, it is not compliant and upon audit, you will be subject to fines and possible plan termination (IRS Rev Proc 2016-17). If your plan is out of date, your best option is to restate your plan to make sure it is compliant with current law. On average, most plan documents we see update every two to three years as the laws effecting the plan documents change. We’ve had two different plan amendments to our IRS pre-approved plan in the past six years.

3. Are you properly tracking your plan funds?

Your Solo 401(k) plan funds need to be properly tracked and they must identify the different sources for each participant. For example, if two spouses are contributing Roth 401(k) employee contributions and the company is matching employer Traditional 401(k) dollars, then you need to be tracking these four different sources of funds, and you must have a written accounting record documenting these different fund types.

4. Plan funds must be separated by source and participant

You must maintain separate bank accounts for the different participants’ funds (e.g. spouses or partners in a Solo K), and you must also separate traditional funds from Roth funds. In addition, you must properly track and document investments from these different fund sources so that returns to the Solo 401(k) are properly credited to the proper investing account.

5. Are you properly reporting contributions and rollovers?

If you’ve rolled over funds from an IRA or other 401(k) to your Solo 401(k), you should have indicated that the rollover or transfer was to another retirement account. So long as you did this, the company rolling over the funds will issue a 1099-R to you, but will include a code on the 1099-R (code G in box 7) indicating that the funds were transferred to another retirement account, and that the amount on the 1099-R is not subject to tax.  If you’re making new contributions to the Solo 401(k), those contributions should be properly tracked on your personal and business tax returns. If you are an S-Corp, your employee contributions should show up on your W-2, and your employer contributions will show up on line 17 of your 1120S S-Corp tax return. If you are a Sole Prop, your contributions will typically show up on your personal 1040 on line 28.

Make sure you are complying with these rules on an annual basis. If your Solo 401(k) retirement plan is out of compliance, get with your attorney or CPA immediately to make sure it is up-to-date. Failure to properly file Form 5500 runs at a rate of $25 a day up to a maximum penalty of $15,000 per return not properly filed. You don’t want to get stung for failing to file a relatively simple form. The good news is there are correction programs offered for some plan failures. But, don’t get sloppy, or you’ll run the risk losing your hard-earned retirement dollars.

2018 Solo 401(k) Contribution Steps, Deadlines, and Rules

Image of a red thumbtack on the December 31 date of a calendar.As 2018 comes to an end, it is critical that Solo 401(k) owners understand when and how to make their 2018 contributions. There are three important deadlines you must know if you have a Solo 401(k) or if you plan to set one up still in 2018. A Solo 401(k) is a retirement plan for small business owners or self-employed persons who have no other full time employees other than owners and spouses. It’s a great plan that can be self-directed into real estate, LLCs, or other alternative investments, and allows the owner/participants to contribute up to $55,000 per year (far faster than any IRA).

New Solo 401(k) Set-Up Deadline is 12/31/18

First, in order to make 2018 contributions, the Solo 401(k) must be adopted by your business by December 31st, 2018. If you haven’t already adopted a Solo 401(k) plan, you should start now so that documents can be completed and filed in time. If the 401(k) is established on January 1st, 2019 or later, you cannot make 2018 contributions.

2018 Contributions Can Be Made in 2019

Both employee and employer contributions can be made up until the company’s tax return deadline including extensions. If you have a sole proprietorship (e.g. single member LLC or schedule C income) or C-Corporation, then the company tax return deadline is April 15th, 2018. If you have an S-Corporation or partnership LLC, the deadline for 2018 contributions is March 15th, 2019. Both of these deadlines (March 15th and April 15th) to make 2018 contributions may be extended another six months by filing an extension. This a huge benefit for those that want to make 2018 contributions, but won’t have funds until later in the year to do so.

W-2’s Force You to Plan Now

While employee and employer contributions may be extended until the company tax return deadline, you will typically need to file a W-2 for your wages (e.g. an S-Corporation) by January 31st, 2019. The W-2 will include your wage income and any deduction for employee retirement plan contributions will be reduced on the W-2 in box 12. As a result, you should make your employee contributions (up to $18,500 for 2018) by January 31st, 2019 or you should at least determine the amount you plan to contribute so that you can file an accurate W-2 by January 31st, 2019. If you don’t have all or a portion of the funds you plan to contribute available by the time your W-2 is due, you can set the amount you plan to contribute to the 401(k) as an employee contribution, and will then need to make said contribution by the tax return deadline (including extensions).

Example

Now let’s bring this all together and take an example to outline how this may work. Sally is 44 years old and has an S-Corporation as an online business. She is the only owner and only employee, and had a Solo 401(k) established in 2018. She has $120,000 in net income for the year and will have taken $50,000 of that in wage income that will go on her W-2 for the year. That will leave $70,000 of profit that is taxable to her and that will come through to her personally via a K-1 from the business. Sally has not yet made any 2018 401(k) contributions, but plans to do so in order to reduce her taxable income for the year and to build a nest egg for retirement. If she decided to max-out her 2018 Solo 401(k) contributions, it would look like this:

  1. Employee Contributions – The 2018 maximum employee contribution is $18,500. This is dollar for dollar on wages so you can contribute $18,500 as long as you have made $18,500. Since Sally has $50,000 in wages from her S-Corp, she can easily make an $18,500 employee contribution. Let’s say that Sally doesn’t have the $18,500 to contribute, but will have it available by the tax return deadline (including extensions). What Sally will need to do is let her accountant or payroll company know what she plans to contribute as an employee contribution so that they can properly report the contributions on her payroll and W-2 reporting. By making an $18,500 employee contribution, Sally has reduced her taxable income on her W-2 from $50,000 to $31,500. At even a 20% tax bracket for federal taxes and a 5% tax bracket for state taxes that comes to a tax savings of $4,625.
  1. Employer Contributions – The 2018 maximum employer contribution is 25% of wage compensation. For Sally: Up to a maximum employer contribution of $36,500. Since Sally has taken a W-2 wage of $50,000, the company may make an employer contribution of $12,500 (25% of $50,000). This contribution is an expense to the company and is included as an employee benefit expense on the S-Corporation’s tax return (form 1120S). In the stated example, Sally would’ve had $70,000 in net profit/income from the company before making the Solo 401(k) contribution. After making the employer matching contribution of $12,500 in this example, Sally would then only receive a K-1 and net income/profit from the S-Corporation of $57,500. Again, if she were in a 20% federal and a 5% state tax bracket, that would create a tax savings of $3,125. This employer contribution would need to be made by March 15th, 2019 (the company return deadline) or by September 15th, 2019 if the company were to file an extension.

In the end, Sally would have contributed and saved $31,000 for retirement ($18,500 employee contribution, $12,500 employer contribution). And she would have saved approximately $7,750 in federal and state taxes. That’s a win-win.

Keep in mind, you need to start making plans now and you want to begin coordinating with your accountant or payroll company as your yearly wage information on your W-2 (self employment income for sole props) is critical in determining what you can contribute to your Solo 401(k). Also, make certain you have the plan set-up in 2018 if you plan to make 2018 contributions. While IRAs can be established until April 15th, 2019 for 2018 contributions, a Solo K must be established by December 31st, 2018. Don’t get the two confused, and make sure you’ve got a plan for your specific business.

Note: If you’ve got a single member LLC taxed as a sole proprietorship, or just an old-fashioned sole prop, or even or an LLC taxed as a partnership (where you don’t have a W-2), then please refer to our prior article here on how to calculate your Solo K contributions as they differ slightly from the s-corp example above.
