The good news? You get access to some of the most powerful retirement plans available, with contribution limits much higher than the average employee gets.

In 2025, the smartest move is to:

• Start with a Roth or Traditional IRA

• Move to SEP IRA if you want simple, higher contributions

• Graduate to Solo 401(k) for full flexibility and tax strategy

Don’t wait until your 40s or 50s. With compound interest, the earlier you start, the bigger the outcome.

📌 Pro tip: Combine plans! You can contribute to both a Solo 401(k) and a Roth IRA if you qualify.

Plan now, save consistently — and let time and smart tax planning work for you.
