Solo 401k plans are very similar to their corporate counterparts and fall under the same rules and requirements.
However, solo 401k plan holders have a unique opportunity, as they are both the employer and employee. As such, they can have two contributions to their plan: elective and non-elective.
Elective Deposits
Elective deposits are the regular contributions that you decide to make from your earned income, up to 100% of your compensation.
The yearly limit for elective deposits in 2019 is $19,000, which is up $500 from 2018. For plan holders that are 50 years and older, there’s an additional $6,000 allowance, permitting a contribution total of $25,000.
You can make traditional pre-tax deposits to reduce your taxable income during your peak working years. Or, if you think your future holds a higher tax bracket, you could pay the tax upfront on Roth deposits and get tax-free earnings in retirement.
Non-Elective Deposits
Non-elective deposits are the contributions towards your retirement savings by the business owner.
In a corporate 401k, non-elective deposits are the employer’s matching contribution (or, profit-sharing). In a solo 401k, you can dictate the level of matching contributions, up to 25% of your compensation.
The yearly limit for non-elective deposits in 2018 cannot exceed $55,000, up $1000 from 2017.
Reporting To The IRS
When your plan reaches $250,000 in value, you’ll have to file an annual report using Form 5500-SF.
Plan Withdrawals
If you try to draw upon your earnings before the age of 59½, or before the account is aged 5 years, you’ll trigger a 10% penalty tax on your earnings. If you grew your savings with traditional deposits, you’ll also owe income taxes on each distribution.
Keep in mind, these limits apply to each person and not each plan. If you have another job with a 401k account you’ll have to make sure your combined deposits (elective & non-elective) don’t exceed the IRS guidelines. The IRS changes the contribution limits to offset inflation, so check back often.
