Question 1: Does my 401(k) contribution amount come from my gross pay or net pay? How will my contribution to my Self-Employed 401(k) affect my take-home pay?

When discussing Self-Employed 401(k) plans with our clients, we are often asked how the contributions to this type of retirement savings plan will affect take-home pay.

Answer: Your contribution amount comes from your gross pay (before any taxes and deductions are taken out).

As far as how it will affect your take-home pay, your net paycheck will be reduced by the contribution amount less your marginal tax rate. For example, if you contribute $100 each paycheck to your Self-Employed 401(k) and your marginal tax rate is 22%, your net payroll check will only be reduced by $78 ($100 – $22 = $78).

Question 2: What’s the maximum amount I can contribute into the self-employment plan using both a 401(k) and my company-sponsored profit-sharing plan for 2024?

Answer: The Self-Employed 401(k) combined with a profit-sharing feature allows a total contribution of up to $70,000 in 2025 for those under age 50. For individuals aged 50 to 59, the maximum increases to $77,500, including the standard $7,500 catch-up contribution. Those between ages 60 and 63 can contribute up to $81,250, as the catch-up amount rises to $11,250 under new rules. For individuals aged 64 and older, the maximum contribution returns to $77,500 with the standard catch-up.

Question 3:  If I’m still working and have a balance in a company-sponsored 401(k) account with my current employer, am I required to begin taking a required minimum distribution (RMD) from the employer-sponsored plan when I turn 73?

Answer: No, unless you own more than five percent of the company. RMDs for this employer-sponsored plan don’t begin until you retire. However, this exemption doesn’t apply to your other retirement plans, such as IRAs and other 401(k) plans from prior employers. You are still required to take RMDs from your other retirement accounts at age 73.

Please Note: The Secure Act 2.0 raised the RMD age from 72 to 73 for tax years beginning 2023, and it’s scheduled to raise the age again to 75 by 2033. The updated legislation, does not apply to individuals born in 1950 or earlier, who must continue taking RMDs for 2022 and beyond.

Question 4: Can I withdraw a combined RMD amount, which represents the total RMD requirement from all my retirement accounts, from one retirement account?

Answer: Not for every type of retirement account. IRAs can be aggregated value-wise, and the RMD withdrawal can be from one individual IRA. However, 401(k) RMDs cannot be combined and are required to be withdrawn annually from each 401(k) account.

It can be tricky to keep up with IRS regulations and the tax code, both of which constantly evolve. Working with a financial professional can help you ensure that you are maximizing your savings while minimizing your tax burden as you prepare for retirement.
