One advantage a 401(k) offers over an IRA is that you can borrow from a 401(k). If you opt for Solo Roth 401(k), there’s no deduction, but withdrawals are tax-free if you wait until you’re 59½. The plan lets you save much more than a Roth IRA. Another advantage for the Solo Roth 401(k) is that contributions aren’t subject to income limits (unlike the Roth IRA).
Which is better… a Roth or traditional IRA?It depends on many factors. If you expect to be in a higher tax bracket in the future, the Roth version may make more sense, but if your current tax rate is low, it might be better to forgo a deduction now in order to withdraw money tax-free when you’re in a higher bracket in the future. What’s nice is that it doesn’t have to be an “either-or” proposition: you can have both traditional and Roth 401(k) plans and divide contributions between them.
For most self-employed individuals, the SEP-IRA may be a better choice than a traditional IRA because the contribution limits are much higher. Also, deductions for traditional IRA contributions are limited by income for participants who are covered or whose spouse is covered by a retirement plan at work.
