**Based on 2024 IRS Tax Tables. This chart represents an unincorporated, self-employed, married individual under age 50 with two dependent children, filing jointly. The individual has net business income of $100,000 and the spouse has no earned income. The chart shows the difference between the tax due if no contributions are made and the tax due if the maximum contribution is made to an Individual 401(k) Plan. While personal exemptions have been eliminated, there is a child tax credit each child for 2024, subject to phase-out at a higher income level. This calculation has not taken into account the pass-through deduction that may be available. Actual savings will vary depending on your personal circumstances and the availability of the pass-through deduction. Please consult with your tax advisor to discuss your specific situation.

¹An annual $20 account service fee is charged for each mutual fund account with a balance below $10,000. The $20 account service fee will be waived for the following circumstances: Subscribe to electronic delivery of statements and confirmations; maintain an individual combined balance of $50,000 or more for all T. Rowe Price accounts (including mutual funds, Brokerage, and Small Business Retirement Plans); or qualify for the T. Rowe Price Summit Program. Participants can subscribe to paperless delivery via T. Rowe Price Workplace Retirement once their account is established. If the Participant Account is closed during the year, a $20 closeout fee will be deducted automatically from the proceeds of the total redemption. However, the closeout fee is waived when an account service fee was previously assessed to the participant account for that year or when the proceeds are being used for a rollover, transfer or conversion to a T. Rowe Price retirement plan account or T. Rowe Price IRA.
