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.

DISTRIBUTIONS FROM YOUR RETIREMENT ACCOUNT: THE TOP TEN LIST

I’m routinely asked questions about what taxes and rules apply when a distribution occurs from a retirement account. Here are the top ten rules you should know about distributions from retirement accounts.

The First 5 Facts Apply to Traditional IRA and 401(k) Accounts.

1. Early Withdrawal Penalty. A distribution from a traditional IRA or 401(k) before the account owner reaches 59 1/2 causes a 10% early withdrawal penalty on the amount distributed. This is in addition to taxes owed on the amount distributed. So, for example, if you take a $10,000 distribution from your traditional IRA at age 45 then you will be subject to a $1,000 penalty and you will also receive a 1099-R from your IRA custodian and will need to report $10,000 of income on your tax returns. Once you reach age 59 1/2, the 10% early withdrawal penalty does not apply.

2. Required Minimum Distributions. Whether you need the money or not, at age 70 1/2, the IRS requires a traditional IRA or 401(k) owner (unless still employed by employer 401(k)) to begin taking distributions from their retirement account. These distributions are subject to tax and the account owner will receive a 1099-R of the amount distributed that will be included on their tax return. The amount of the distribution is based on the person’s age and the account’s value. For example, someone with a $100K IRA who has turned 70 1/2 and is taking their first RMD would take $3,639 (3.79%).

3. Avoid Taking Large Distributions In One-Year. Because distributions from traditional retirement accounts are subject to tax at the time of distribution, it is wise to avoid taking too much in one year as a large distribution can push your distribution income and your other income into a higher tax bracket. For example, if you have  employment and or rental/investment income of $50,000 annually then you are in a joint income tax bracket of 15% on additional income. However, if you take $100,000 as a lump-sum that year this will push your annual income to $150K and you will be in a 28% income tax bracket. If you could instead break up that $100K over two tax years then you could stay in 15% to 25% tax bracket and could reduce your overall tax liability. In short, only pull out what you need when you need it to lesson the immediate year’s tax liability.

4. Distribution Withholding. Most distributions from an employer 401(k) or pension plan (including solo K), before the age of 59 1/2, will be subject to a 20% withholding that will be sent to the IRS in anticipation of tax and penalty that will be owed. In the case of an early distribution from an IRA, a 10% withholding for the penalty amount can be made but you can also elect out of this automatic withholding provided you make an estimated tax payment or that you will otherwise be current on your tax liability.

5. If You Have Tax Losses, Consider Converting to a Roth IRA or Roth 401(k). When you have tax losses on your tax return you may want to consider using those losses to offset income that would arise when you convert a traditional IRA or 401(k) to a Roth account. Whenever you convert a traditional account to a Roth account, you must pay tax on the amount of the conversion. In the end though, you’ll have a Roth account that grows entirely tax-free and that you don’t pay taxes on when you distribute the money. Using the losses when they are available is a good way to get your Traditional retirement funds over to Roth.

The Final 5 Rules are For Roth IRAs and Roth 401(k)s.

1. Roth IRAs Are Exempt from RMD. While traditional IRA owners must take required minimum distributions (“RMD”) when the account owner reaches age 70 1/2, Roth IRAs are exempt from RMD rules. That’s a great perk and allows you to keep your money invested as long as possible.

2. Roth 401(k)s Must Take RMD. Roth 401(k) designated accounts are subject to RMD. This is a confusing rule since Roth IRAs are NOT subject to RMD. Such is the tax code. How can you avoid this?  Simply roll your Roth 401(k) funds over to a Roth IRA when you reach 70 1/2.

3. Distributions of Contributions Are Always Tax-Free. Distributions of contributions to a Roth IRA are always tax-free. Regardless of age, you can always take a distribution of your Roth IRA contributions without penalty or tax.

4. Distributions of Roth IRA Earnings. In order to take a tax-free distribution from a Roth IRA, you must be age 59 1/2 or older and you must have had a Roth IRA for five years or longer. As long as those two criteria are met, all amounts (contributions and earnings) may be distributed from a Roth IRA tax free. If your funds in the Roth IRA are from a conversion, then you must have converted the funds at least 5 years ago and must be 59 1/2 or older in order to take a tax-free distribution.

5. Delay Roth Distributions. Roth retirement accounts are the most tax efficient way to earn income in the U.S. As a result, it is best to distribute and use other funds and assets that are at your disposal before using the funds built up in your Roth account as those funds aren’t as tax efficient while invested.
