Ready to Supercharge Your Self-Employed Retirement Savings? Let's Get Started!
Are you a self-employed individual, a freelancer, or a business owner with no full-time employees? If so, you've likely heard of the incredible power of a Solo 401(k). This retirement plan allows you to contribute to your retirement savings as both an employee and an employer, offering much higher contribution limits than a traditional IRA or SEP IRA. And if you're looking for a low-cost, straightforward platform to manage your investments, Vanguard is a name that often comes to mind.
In this comprehensive, step-by-step guide, we'll walk you through the entire process of opening a Solo 401(k) with Vanguard's plan administrator, Ascensus, and get you on the fast track to building a robust retirement nest egg. Let's dive in!

| How To Open Solo 401k Vanguard |
Step 1: Determine Your Eligibility and Gather Your Information
Before you can even think about opening the account, the very first thing you need to do is confirm that you qualify for a Solo 401(k). So, ask yourself:
Do I have self-employment income? This is the most crucial requirement. Your income can come from a sole proprietorship, partnership, LLC, or corporation.
Do I have any full-time employees? The "Solo" in Solo 401(k) is key. You cannot have any full-time employees who work more than 1,000 hours per year, except for yourself and your spouse if they also work in the business. If you hire a full-time employee later, you will need to update your plan to include them, which can add significant administrative complexity.
If you answered yes to the first question and no to the second, congratulations! You are eligible.
Now, let's get your ducks in a row. You will need some key information to complete the application process:
Your Employer Identification Number (EIN). If you're a sole proprietor using your Social Security number, you'll need to apply for a free EIN from the IRS before you can open the plan. This is a critical step.
Your personal information, including your Social Security number, date of birth, and address.
Your business name and address.
Your bank account and routing numbers for funding the account.
Your estimated self-employment income for the year. This will help you determine your potential contribution limits.
Step 2: Contact Vanguard's Plan Administrator
Here’s a crucial detail: Vanguard no longer directly administers Solo 401(k) plans. Instead, they partner with a third-party administrator, Ascensus. The good news is that this plan still features Vanguard's famously low-cost investment options.
You have two main options for starting the process:
If you are a new Vanguard client: The most direct way to get started is to call Vanguard at 1-800-992-1788. A representative will be able to walk you through the application process for the Individual 401(k) featuring Vanguard investments.
If you are an existing Vanguard client: You may be able to set up the account online by logging into your account and selecting "Individual 401(k)." However, it is often recommended to call to ensure you are setting up the correct type of plan and to get assistance with the paperwork.
Pro Tip: It can be incredibly helpful to have a representative on the phone with you for your first time setting up the plan. Don't hesitate to call and ask for assistance. They can guide you through the forms and ensure everything is filled out correctly.
Tip: Reread slowly for better memory.
Step 3: Complete the Solo 401(k) Plan Documents
This is where the paperwork comes in. The representative you speak with will guide you through this process, but here's a general idea of what you'll be doing:
Establish the Plan: You will set up the official Solo 401(k) plan for your business. This involves creating a plan document that outlines the rules of the plan. Ascensus will provide you with the necessary documents.
Open the Accounts: You will need to open two separate accounts within the Solo 401(k) structure:
A brokerage account where you will hold your investments.
A trust account for the plan's assets.
Choose Your Contribution Type(s): A key advantage of the Solo 401(k) is the flexibility to contribute in two ways:
Pre-tax (Traditional) contributions: These contributions are tax-deductible in the current year, and your earnings grow tax-deferred. You'll pay taxes on withdrawals in retirement.
Roth (after-tax) contributions: You contribute with after-tax dollars, but your qualified withdrawals in retirement are completely tax-free.
You can choose to make both types of contributions. This allows for a great deal of tax planning flexibility.
Step 4: Understand and Make Your Contributions
Now for the exciting part—funding your account! This is where the Solo 401(k) truly shines. You can contribute in two capacities:
As an Employee (Salary Deferral)
For 2025, the employee contribution limit is $23,500.
If you are age 50 or older, you can contribute an additional $7,500 as a "catch-up" contribution, bringing your employee total to $31,000.
You can contribute up to 100% of your compensation as an employee, up to this limit.
As an Employer (Profit-Sharing)
As the employer, you can contribute up to 25% of your compensation.
For self-employed individuals, "compensation" is defined as your net earnings from self-employment after deducting one-half of your self-employment tax and the contributions you made for yourself. This calculation can be a bit complex, so it's a good idea to consult with a tax professional.
Total Contribution Limit for 2025
The combined employee and employer contributions cannot exceed a total of $70,000 for 2025. If you are 50 or older, the total can go up to $77,500 including the catch-up contribution.
QuickTip: Skim first, then reread for depth.

Important Deadlines:
Employee contributions: You must make your election for salary deferrals by the end of your business's fiscal year.
Employer contributions: The deadline to make employer contributions is your business's tax filing deadline, including extensions.
Step 5: Choose Your Investments and Manage Your Account
Once your account is funded, it's time to invest! With the Solo 401(k) featuring Vanguard investments, you'll have access to a wide range of their low-cost mutual funds and ETFs.
Vanguard Mutual Funds: Known for their incredibly low expense ratios, these funds are a hallmark of Vanguard's investor-first philosophy.
Vanguard ETFs (Exchange-Traded Funds): These are like mutual funds that trade like stocks. You can buy and sell Vanguard ETFs commission-free online through Vanguard Brokerage Services.
Important Note on Fees: While there are no setup fees for the Solo 401(k), there is a $20 annual fee for each Vanguard mutual fund held in the account. This fee is waived if you have at least $50,000 in qualifying Vanguard assets. This is a great incentive to consolidate your investments with them.
Step 6: Understand the Ongoing Administration and Compliance
The Solo 401(k) requires a bit more administration than a SEP IRA, but it's manageable.
Form 5500-EZ Filing: Once your plan's assets reach $250,000 at the end of the year, you are required to file Form 5500-EZ with the IRS. Ascensus, as the plan administrator, will provide you with the information you need to complete this form.
Recordkeeping: Keep good records of your contributions and any distributions.
Beneficiaries: Make sure you designate and keep your beneficiaries updated.
This may sound complex, but for many self-employed individuals, the benefits of higher contribution limits and a Roth option far outweigh the administrative burden.
