Self-Employment Income In Retirement? Use a Solo(k) Plan To Build Wealth

Self-Employment Income In Retirement? Use a Solo(k) Plan To Build Wealth

It’s becoming more common for retirees to take on small self-employment gigs in retirement to generate some additional income and to stay mentally active and engaged.  But, it should not be overlooked that this is a tremendous wealth-building opportunity if you know the right strategies.  There are many, but in this article, we will focus on the “Solo(k) strategy.” 

What Is A Solo(K)

A Solo(k) plan is an employer-sponsored retirement plan that is only allowed to be sponsored by owner-only entities.   It works just like a 401(k) plan through a company but without the high costs or administrative hassles.  The owner of the business is allowed to make both employee deferrals and employer contributions to the plan.

Solo(k) Deferral Limits

For 2023, a business owner is allowed to contribute employee deferrals up to a maximum of the LESSER of:

• 100% of compensation; or

• $30,000 (Assuming the business owner is age 50+)

Pre-tax vs. Roth Deferrals

Like a regular 401(K) plan, the business owner can contribute those employee deferrals as all pre-tax, all Roth, or some combination of the two.  Herein lies the ample wealth-building opportunity.  Roth assets can be an effective wealth accumulation tool.  Like Roth IRA contributions, Roth Solo(k) Employee Deferrals accumulate tax deferred, and you pay NO TAX on the earnings when you withdraw them as long as the account owner is over 59½ and the Roth account has been in place for more than five years. 

Also, unlike Roth IRA contributions, there are no income limitations for making Roth Solo(k) Employee Deferrals and the contribution limits are higher.  If a business owner has at least $30,000 in compensation (net profit) from the business, they could contribute the entire $30,000 all Roth to the Solo(K) plan.   A Roth IRA would have limited them to the max contribution of $7,500 and they would have been excluded from making that contribution if their income was above the 2023 threshold.

A quick note, you don’t necessarily need $30,000 in net income for this strategy to work; even if you have $18,000 in net income, you can make an $18,000 Roth contribution to your Solo(K) plan for that year.  The gem to this strategy is that you are beginning to build this war chest of Roth dollars, which has the following tax advantages down the road……

Tax-Free Accumulation and Withdrawal:  If you can contribute $100,000 to your Roth Solo(k) employee deferral source by the time you are 70, if you achieve a 6% rate of return at 80, you have $189,000 in that account, and the $89,000 in earnings are all tax-free upon withdrawal.

No RMDs:  You can roll over your Roth Solo(K) deferrals into a Roth IRA, and the beautiful thing about Roth IRAs are no required minimum distributions (RMD) at age 72.  Pre-tax retirement accounts like Traditional IRAs and 401(k) accounts require you to begin taking RMDs at age 72, which are forced taxable events; by having more money in a Roth IRA, those assets continue to build.

Tax-Free To Beneficiaries: When you pass assets on to your beneficiaries, the most beneficial assets to inherit are often a Roth IRA or Roth Solo(k) account.   When they changed the rules for non-spouse beneficiaries, they must deplete IRAs and retirement accounts within ten years. With pre-tax retirement accounts, this becomes problematic because they have to realize taxable income on those potentially more significant distributions.  With Roth assets, not only is there no tax on the distributions, but the beneficiary can allow that Roth account to grow for another ten years after you pass and withdraw all the earnings tax and penalty-free.

Why Not Make Pre-Tax Deferrals?

It's common for these self-employed retirees to have never made a Roth contribution to retirement accounts, mainly because, during their working years, they were in high tax brackets, which warranted pre-tax contributions to lower their liability.   But now that they are retired and potentially showing less income, they may already be in a lower tax bracket, so making pre-tax contributions, only to pay tax on both the contributions and the earnings later, may be less advantageous.  For the reasons I mentioned above, it may be worth foregoing the tax deduction associated with pre-tax contributions and selecting the long-term benefits associated with the Roth contributions within the Solo(k) Plan.

Now there are situations where one spouse retires and has a small amount of self-employment income while the other spouse is still employed.  In those situations, if they file a joint tax return, their overall income limit may still be high, which could warrant making pre-tax contributions to the Solo(k) plan instead of Roth contributions.  The beauty of these Solo(k) plans is that it’s entirely up to the business owner what source they want to contribute to from year to year. For example, this year, they could contribute 100% pre-tax, and then the following year, they could contribute 100% Roth. 

Solo(k) versus SEP IRA

Because this question comes up frequently, let's do a quick walkthrough of the difference between a Solo(k) and a SEP IRA. A SEP IRA is also a popular type of retirement plan for self-employed individuals; however, SEP IRAs do not allow Roth contributions, and SEP IRAs limit contributions to 20% of the business owner’s net earned income.  Solo(K) plans have a Roth contribution source, and the contributions are broken into two components, an employee deferral and an employer profit sharing.

As we looked at earlier, the employee deferral portion can be 100% of compensation up to the Solo(K) deferral limit of the year, but in addition to that amount, the business owner can also contribute 20% of their net earned income in the form of a profit sharing contribution.

When comparing the two, in most cases, the Solo(K) plan allows business owners to make larger contributions in a given year and opens up the Roth source.
