What is a 401(k)?
A 401(k) is a type of retirement savings plan that allows you to save money for your future while reducing your taxable income.
You might have thought that only employees of big companies could have a 401(k), but that's not true.
Setting Up and Managing a 401(k)

Setting up a 401(k) plan is a straightforward process that typically takes a few weeks to a few months to complete. You'll need to choose a plan provider and decide on the type of plan you want.
You can contribute up to 20% of your income to a 401(k) plan, and the money is taken out of your paycheck before taxes are applied, reducing your taxable income. This can be a great way to save for retirement.
A 401(k) plan allows you to choose from a variety of investment options, including stocks, bonds, and mutual funds.

Eligibility Requirements
To qualify for a solo 401(k), you must produce your income from your own business, which can take any form such as a sole proprietorship, LLC, corporation, or partnership.
Sole proprietors and small business owners without employees, except for a spouse, typically fit this description.
Your business must produce income, which is verified through your tax records.
This means that if you're an independent contractor or freelancer with no employees, you can open a solo 401(k) plan.
Business owners can exclude certain employees under the Secure Act 2.0, including those under age 21 and long-term part-time employees who work less than 1,000 hours a year.
You can also exclude employees who have not worked at least 500 hours in two years in a row.
To be eligible, your business must be run by you alone, or you and your spouse.

Set Up Retirement Account
To set up a retirement account, you'll need to decide which type of account is right for you. The most common option is a 401(k) plan, which is offered by many employers.
The employer will typically match a portion of your contributions, which can significantly boost your savings. For example, if your employer matches 50% of your contributions, that's essentially free money.
You can contribute to a 401(k) plan through payroll deductions, making it easy to save money regularly. The annual contribution limit for 2022 is $19,500, or $26,000 if you're 50 or older.
It's essential to start saving as early as possible to take full advantage of compound interest and grow your retirement nest egg.

401(k) Options and Limits
The solo 401(k) offers high contribution limits, allowing you to save for retirement at a faster pace.
You can contribute up to $70,000 for 2025, or 25% of your adjusted gross income, whichever is less.
People age 50 and older can add an extra $7,500 a year as a "catch-up contribution" in 2024 and 2025.
In contrast, a SEP IRA contribution limit is only 25% of employee compensation and does not permit elective deferrals or catch-up contributions.
A solo 401(k) allows for all three: employer contributions, elective deferrals, and catch-up contributions, giving you more flexibility in your savings strategy.
As an employee, you can contribute up to $19,500 in 2021, and if you're over 50, you can contribute an additional $6,500 in catch-up contributions, adding up to $26,000.
As the employer, you can contribute up to $37,500, as long as this amount does not exceed 20% of your self-employment income.

Compliance Plan Documents
You'll receive plan documents that are compliant with government regulations, and this is a big deal because it ensures your 401(k) plan meets all the necessary requirements.
These plan documents are carefully crafted to meet the specific needs of your company, and they'll be reviewed and approved by the relevant authorities.
The IRS will also issue a Determination letter confirming that your 401(k) plan meets the requirements of a qualified plan, giving you peace of mind that you're on the right track.
This letter is a formal confirmation that your plan has passed the test, and it's a crucial document that you'll need to keep on file.
Traditional or Roth?
You have two main options for your solo 401(k) plan: traditional or Roth. With a traditional 401(k), you're investing with pretax dollars, which means you're claiming an immediate tax break for your contributions as you make them throughout your working years.
You'll owe income taxes on the funds as you withdraw them in retirement, which could be a big hit if you're in a higher tax bracket then. Most people are in a lower tax bracket after retiring than they were during their working years, so this might not be as big of a deal.

Roth plans, on the other hand, are funded with after-tax dollars, which means you've already given the IRS its cut. This means your withdrawals are tax-free after you retire, as long as you've had the account for over five years.
This could add up to a nice fat bank account for your retirement years, but it's a bigger hit to your spending power during your working years. A solo 401(k) must be set up by Dec. 31 in the tax year for which you are making contributions.
High Limits
You can contribute up to $70,000 for 2025, up from $69,000 in 2024, or 25% of your adjusted gross income, whichever is less.
The contribution limits are adjusted for inflation every year by the IRS. This means the limits may change over time, so it's essential to check the current limits before making any contributions.
People age 50 and older can add an extra $7,500 a year as a "catch-up contribution" in 2024 and 2025. This can be a significant boost to your retirement savings.

As the employer, a Solo 401(k) allows you to contribute up to $37,500, as long as this amount does not exceed 20% of your self-employment income. This can be a great way to save for retirement and reduce your tax liability.
Combining employee and employer contributions allows older workers to save up to $76,500 per year in 2025. This is significantly higher than most other retirement plans, allowing for accelerated retirement savings.
You can contribute as both employer and employee, making a Solo 401(k) a highly flexible retirement savings option. This flexibility can be especially beneficial for self-employed individuals or small business owners.

Exemption from UDFI
Exemption from UDFI provides a significant tax advantage to business owners using a Solo 401(k) plan to purchase real estate.
With a Solo 401(k), you can avoid paying the Unrelated Debt Financed Income Tax (UDFI tax) on leveraged real estate. This means you won't owe taxes on the net rental proceeds or net profits obtained from selling the property.
A unique perspective: 401k Real Estate Investment Rules

If you buy a real estate property at $100,000 and borrow $50,000, you have 50% debt on the property. In an IRA environment, you'd pay UDFI taxes on 50% of the net profits from the property.
However, with a Solo 401(k) investment, there's no UDFI tax on debt on real estate. Any income earned from the property will grow tax-deferred, even with a $50,000 loan.
