How do I make contributions to my Solo 401(k)?

Solo 401(k) contributions are deposited directly into your plan's bank account. There is no custodian intermediary as there is with an IRA. The process is straightforward once you've determined your contribution amount and timing.

Step 1: Determine your contribution strategy

Work with your tax advisor to determine how much you can contribute, which contribution types apply to your situation (employee deferral, employer profit-sharing, or both), and when to make the deposits. Contribution limits and the deductibility of each contribution type depend on your business structure and income.

Step 2: Deposit funds into your plan account

Transfer funds from your business bank account into your Solo 401(k) plan checking account by check, wire, or ACH. Contributions should come from your business account, not a personal account, to maintain a clear link between business income and plan contributions.

Step 3: Record the contribution

Log each deposit in the 401(k) Contribution Log included with your Self-Directed Plans plan documents. Record the date, amount, contribution type, and participant account. This log supports your tax deductions, maintains accurate participant account balances, and provides the data needed for Form 5500-EZ if your plan is required to file.
