You can contribute up to 20% of your income to an individual 401k, with a maximum annual contribution limit of $57,000.
Having an individual 401k can give you a significant tax break, allowing you to reduce your taxable income by the amount you contribute.
The individual 401k tax deduction can be especially beneficial for self-employed individuals or small business owners who have high incomes and want to save for retirement.
By contributing to an individual 401k, you can also reduce your self-employment tax liability.
What is a plan?
A plan can be tailored to fit your individual needs, and with a 401(k), you can contribute up to $22,500 in 2023 or $23,000 in 2024.
You can also make catch-up contributions if you're 50 or older, adding an extra $7,500 to your total contribution limit in 2023 or 2024.
These contributions can be made through your payroll, so it's essential to get that extra money into your account by December 31 of each year.

Your employer's matching contribution doesn't affect your own contribution limit, so you can still contribute up to $22,500 in 2023 or $23,000 in 2024, even if your employer is matching that amount.
Most employer contributions aren't taxable to you when they're made, but you'll have to pay taxes on the money when you withdraw it, unless you rollover to an IRA or other employer retirement plan.
The overall limit on combined contributions made by you and your employer is $66,000 for 2023, or $69,000 for 2024.

Eligibility and Eligible Businesses
To be eligible for an individual 401(k), you don't have to meet any specific age or income requirements, but you do need to be a business owner with no employees.
You can have a solo 401(k) if you're a business owner with no employees, making it a great option for freelancers and solo entrepreneurs.
The eligibility rules are relatively straightforward, and you can open a solo 401(k) as long as you have an employer identification number.
Here are the key eligibility rules for a solo 401(k) in bullet points:
- No age or income restrictions
- Must be a business owner with no employees
Contribution Limits and Rules
The contribution limits and rules for an individual 401(k) are a bit complex, but don't worry, I've got you covered.
The Internal Revenue Service (IRS) updates the contribution limit annually based on inflation and other factors. For 2023, the contribution limit is $22,500 and for 2024, the employee contribution limit is $23,000.
As an employee, you can contribute up to $22,500 in 2023 and $23,000 in 2024, and if you're 50 or older, you can make an additional catch-up contribution of $7,500 for a total of $30,000 in 2023 and $30,500 in 2024.
Employer contributions to a 401(k) don't affect your own contribution limit, so you can still contribute the maximum amount even if your employer matches your contributions.
Most employer contributions aren't taxable to you when they're made, but you'll have to pay taxes on the money when you withdraw it, unless you rollover to an Individual Retirement Account (IRA) or other employer retirement plan like a 401(k).

The SECURE 2.0 Act permits employers to make their contributions to you as Roth, which means you'll pay taxes on the contribution in the year you receive it, but then the earnings and principal will be tax-free when you withdraw them in retirement.
Your employer may also make non-elective or profit-sharing contributions, which can change year to year and are based on your pay, and there's an overall limit on the combined contributions made by you and your employer of $66,000 for 2023, or $69,000 for 2024.
Solo 401(k) contribution limits are a bit different, as you'll need to consider both your role as an employer and an employee.

Tax Benefits and Deductions
A solo 401(k) offers two tax options: traditional and Roth. The traditional option reduces your income in the year you make contributions, but distributions in retirement will be taxed as ordinary income.
You can choose between a traditional or Roth solo 401(k) based on your income expectations in retirement. If you expect higher income, a Roth is a better option, while lower income means a traditional 401(k) is likely a better choice.
Contributions to a solo 401(k) can reduce your income in the year they are made, but be aware that the IRS has strict rules about when you can tap into the money.

Spouse Coverage in Retirement Plans
Spouse coverage in retirement plans can be a great way to boost your savings, and it's actually allowed by the IRS. One exception to the no-employees rule on the solo 401(k) is your spouse, if they earn income from your business.
Your spouse can make elective deferrals as your employee, up to the employee contribution limit (plus the 50-and-older catch-up provision, if applicable). This could effectively double the amount you can contribute as a family, depending on your income.
As the employer, you can then make the plan's profit-sharing contribution for your spouse, of up to 25% of compensation. This means you can contribute more to your retirement savings, which can be a huge help in the long run.

Tax Deductible?
A solo 401(k) offers a tax advantage, allowing you to choose between a traditional 401(k) and a Roth solo 401(k).
You can opt for the traditional 401(k), which reduces your income in the year contributions are made, but distributions in retirement will be taxed as ordinary income.

A Roth solo 401(k) offers no initial tax break, but allows distributions in retirement to be tax-free.
Experts say a Roth is a better option if you expect your income to be higher in retirement and/or tax brackets to be higher in the future.
You'll pay taxes and penalties on distributions before age 59 ½, with few exceptions.
As both "employee" and "employer" of your business, you'll make two different tax calculations: one for your business' net earnings and one for tax-exempt contributions.
Tax-exempt contributions are a key benefit of a solo 401(k), allowing you to reduce your business' tax liability.

Roth Considerations
In 2023, Roth employer contributions are permitted, but it's up to each business to decide if this provision makes sense for its employees.
Few plans allow Roth employer contributions yet, so if your plan does, you'll have flexibility to decide whether you contribute your savings as Roth or pretax.
You won't see any tax savings in the year you make a Roth contribution, but because you've already paid taxes on the money you contribute, when you withdraw money from a Roth account during retirement, it won't be taxed either.

Having tax-free income in retirement can be especially important when you get there, as it can help keep your Medicare Part B premium low.
If you think you'll have a higher income and be in a higher tax bracket during retirement, making Roth contributions to your 401(k) might make sense, as it will allow you to pay taxes on your income today.
There's no income limit connected to 401(k) Roth contributions, so you won't see your ability to contribute phased out like it is in a Roth IRA.
The limit on employee Roth contributions is the same as the pretax employee contributions, so if you make both pretax and Roth employee contributions, you'll have one $22,500 limit and one $23,000 limit for 2024.

Opening and Managing a Plan
You can open a solo 401(k) at most online brokers, though you'll need an employer identification number.
To get started, you'll need to complete a plan adoption agreement and an account application, which will be provided by the broker.

You'll have access to many investment options, including mutual funds, index funds, exchange-traded funds, individual stocks, and bonds.
To make a contribution for the current year, you must establish the plan by December 31 and make your employee contribution by the end of the calendar year.
You can typically make employer profit-sharing contributions until your tax-filing deadline for the tax year.
Here are the key deadlines to keep in mind:
- Dec. 31: Deadline to establish the plan and make employee contributions for the current year
- Tax-filing deadline: Deadline to make employer profit-sharing contributions
