How to Set Up a Solo 401k

Setting up a Solo 401k is straightforward and advantageous for self-employed individuals. You’ll need an Employer Identification Number (EIN) and a financial institution that offers solo 401k accounts. Choose a plan type: traditional or Roth, then fund the account with pre-tax or post-tax dollars. As the employer, you can contribute up to the annual limit, including both employee and employer contributions. The deadline for opening a Solo 401k and making contributions for a tax year is typically April 15th of the following year. This powerful retirement savings vehicle offers tax-deferred growth and potential investment returns, helping you secure your future financial well-being.

Selecting the Right Plan Type

Choosing the appropriate Solo 401(k) plan type depends on your individual circumstances. The two main options are:

  • Traditional Solo 401(k): Contributions are made pre-tax, reducing your current taxable income. Earnings grow tax-deferred, but withdrawals during retirement are taxed as ordinary income.
  • Roth Solo 401(k): Contributions are made after-tax, so they do not reduce your current taxable income. However, earnings grow tax-free, and withdrawals during retirement are also tax-free.

Consider the following factors when selecting a plan type:

  • Current income and tax bracket: A traditional Solo 401(k) can provide greater tax savings if you are in a high tax bracket now.
  • Expected retirement income and tax bracket: If you anticipate being in a lower tax bracket during retirement, a Roth Solo 401(k) may be more beneficial.
  • Investment horizon: A traditional Solo 401(k) allows for tax-deferred growth over the long term, while a Roth Solo 401(k) offers tax-free growth.

Establishing a Business and EIN

To establish a Solo 401k, you must first establish a business and obtain an Employer Identification Number (EIN). Here’s how:

  • Choose a business structure: You can choose from sole proprietorship, LLC, or S corporation. Each structure has its own tax implications and administrative requirements.
  • Register your business: File the necessary paperwork with your state and locality to register your business and establish your legal entity.
  • Obtain an EIN: Apply for an EIN from the IRS using Form SS-4. The EIN is a unique nine-digit number that identifies your business for tax purposes.
Business StructureTax ImplicationsAdministrative Requirements
Sole ProprietorshipBusiness income and expenses are reported on personal tax returnSimplest and most flexible
LLCBusiness income and expenses are taxed separatelyOffers liability protection
S CorporationBusiness income is taxed only once, at the individual levelMore complex setup and compliance requirements

Funding Your Plan

  • Employer Contributions: You can contribute to your Solo 401(k) as both the employee and the employer. Each year, you can contribute up to 100% of your net self-employment income, but not more than the current annual limit ($66,000 for 2023). Employer contributions are deducted from your business income, reducing your taxable income.
  • Employee Contributions: You can also make employee contributions, which are limited to the lesser of $22,500 ($30,000 if you’re age 50 or older) or 100% of your net self-employment income.
  • Catch-Up Contributions: If you are age 50 or older, you can make catch-up contributions of up to $7,500 in 2023.
  • Roth Contributions: You can also make Roth contributions to your Solo 401(k). Roth contributions are made with after-tax dollars, but they grow tax-free and can be withdrawn tax-free in retirement.
