Mistake 1: Contributing over the income limit
Roth IRA eligibility phases out above certain income levels set by the IRS. If you earn too much and contribute directly anyway, that contribution counts as excess. It faces a 6% penalty tax each year it stays in the account. Check the current limit before you contribute, or use a backdoor Roth through a traditional IRA if you qualify.
Mistake 2: Ignoring the 5-year rule
Even after age 59 and a half, your Roth IRA must be at least five years old for qualified withdrawals. The clock starts on January 1 of the first tax year you contributed. Withdraw earnings before the rule is met and the earnings become taxable income.
Mistake 3: Withdrawing earnings early
You can always withdraw your own contributions tax-free and penalty-free. Earnings are a different story: taking them out before age 59 and a half usually means income tax plus a 10% early withdrawal penalty. Keep contributions and earnings separate in your head, and treat earnings as locked up.
Mistake 4: Forgetting the beneficiary
A Roth IRA passes outside your will directly to the named beneficiary. If the beneficiary line is blank or outdated, the account may go to your estate instead. That means probate instead of a direct transfer to your family. Review your beneficiary designation once a year and after every major life change.
Mistake 5: Missing the pro-rata rule on conversions
If you hold both pre-tax and after-tax money in traditional IRAs, a Roth conversion cannot cherry-pick only the after-tax dollars. The IRS treats every conversion as a proportional mix of both, so part of it is taxable. Run the numbers with a tax professional before converting large balances.
Mistake 6: Overcontributing past the annual limit
For 2026 the IRA contribution limit is $7,500 across all your traditional and Roth IRAs combined. Put in more and the excess is hit with a 6% excise tax every year until you fix it. Track contributions across every account, not just one.
Mistake 7: Assuming an employer plan blocks you
Having a 401(k) at work does not disqualify you from a Roth IRA. Eligibility depends on your income, not on whether you have a workplace plan. Plenty of people contribute to both every year, and the Roth gives you tax-free growth on top of the match.
| Topic | How they compare |
|---|---|
| Contributing over the income limit | Check the IRS limit first, or use a backdoor Roth |
| Ignoring the 5-year rule | Start the clock early, even with a small contribution |
| Withdrawing earnings early | Touch contributions only; leave earnings alone |
| Forgetting the beneficiary | Name a beneficiary and review it yearly |
| Missing the pro-rata rule | Model the tax cost before converting |
| Overcontributing past $7,500 | Track all IRA accounts together |
| Assuming an employer plan blocks you | Use the Roth alongside your 401(k) |
Your records checklist
- Confirm your income is under the Roth IRA phase-out range before contributing.
- Make at least a small contribution to start your 5-year clock now.
- Keep contributions and earnings mentally separate, and never plan on earnings early.
- Name a beneficiary on every IRA and review it after life changes.
Common questions
- Can I contribute to a Roth IRA if I have a 401(k)?
- Yes. A workplace plan does not block Roth IRA eligibility. The limit that matters is your income, not your 401(k). You can fund both in the same year.
- What happens if I put too much into my Roth IRA?
- The excess faces a 6% excise tax each year it remains in the account. You can remove the excess plus any earnings before the tax deadline to fix it. Track all your IRAs together, since the $7,500 limit is shared.
