Mistake 1: Exceeding the Income Limit (Excess Contribution)
Contributing to a Roth IRA when your income exceeds the limit creates an excess contribution subject to a 6% annual excise tax. Fix: withdraw the excess plus earnings before the tax deadline (April 15, including extensions). Or for smaller amounts, apply the excess to next year’s contribution limit. Prevention: check your MAGI before contributing each year, especially if your income is near the phase-out range.
Mistake 2: Over-Contributing Based on Earned Income
Your Roth IRA contribution cannot exceed your earned income for the year. If you earn $4,000 in part-time work, you can only contribute $4,000 — not the full $7,000 limit. Investment income, Social Security, pension, and rental income do not count as earned income. Retirees with no earned income cannot contribute at all unless their spouse works.
Common Roth IRA mistakes and how to fix them
| Common Mistake | Fix | Prevention |
|---|---|---|
| Exceeding income limit | Withdraw excess + earnings before deadline | Check MAGI annually before contributing |
| Contributing more than earned income | Withdraw excess before deadline | Verify W-2 or self-employment income |
| Wrong investments in Roth (bonds, cash) | Reallocate to growth investments | Hold highest-growth assets in Roth IRA |
| Forgetting beneficiary designation | Update immediately at custodian | Review every 5 years or at life changes |
| Not filing Form 8606 for backdoor Roth | File amended return; keep permanent records | Always file 8606 with tax return for non-deductible IRA contributions |
If you make an excess Roth IRA contribution and do not correct it before the deadline, the 6% excise tax applies every year the excess remains in the account. $7,000 excess not corrected for 5 years = $2,100 in cumulative penalties. Fix excess contributions immediately.
Mistakes 3-7 Summary
- Mistake 3: Holding bonds and money market in Roth IRA — wastes the tax-free shelter on low-return assets. Put your highest-growth investments (stocks, REITs) in the Roth.
- Mistake 4: Never naming or updating beneficiaries — the Roth IRA bypasses your will entirely. A missing or outdated beneficiary can send funds to your estate (which loses individual stretch options) or to an ex-spouse.
- Mistake 5: Withdrawing earnings before the 5-year rule or 59½ without understanding tax/penalty consequences — read the rules before making early withdrawals.
- Mistake 6: Converting to Roth without modeling the tax impact — a $100,000 conversion in the wrong year can push you into a 35% bracket, costing far more in taxes than waiting.
- Mistake 7: Thinking the Roth IRA is just a savings account — it is an investment account. Leaving contributions in the default money market rather than investing in growth funds costs you years of compounding.
