Roth IRA Income Limit Calculator 2025 – Eligibility & Phase‑Outs

Introduction

Roth IRA contributions phase out as income rises. Use this guide to check 2025 eligibility by filing status and explore backdoor Roth considerations.

---

Inputs

• Filing status and MAGI
• Age (50+ catch‑up)
• Existing IRA balances (for pro‑rata rules awareness)

---

How Eligibility Works

• Each status has a phase‑out range; contributions reduce linearly within that band
• Over the top range → direct Roth contributions not allowed (consider backdoor)

---

Examples

• Single near top of phase‑out: partial contribution
• MFJ above range: consider backdoor Roth; mind pro‑rata with pre‑tax IRA balances

---

Tips

• Use Traditional IRA then convert (backdoor) if ineligible directly
• Reduce MAGI via 401(k)/HSA to remain eligible for direct Roth
• Track conversions and basis for accurate taxes

Roth IRA Basics and Why MAGI Matters

Roth IRA contributions are made with after‑tax dollars and can grow/withdraw tax‑free if rules are met. However, eligibility for direct contributions phases out as your modified adjusted gross income (MAGI) increases. MAGI expands on AGI by adding back certain items; always consult the latest IRS list for what counts.

---

Step‑by‑Step: Determine Your Direct Contribution Eligibility

1. Start with AGI from your tax projection
2. Adjust to MAGI per IRS rules
3. Identify your filing status threshold and phase‑out band
4. If within the band → allowable contribution is prorated
5. If above the band → consider the backdoor Roth path

Phase‑Out Illustration (Not Actual 2025 Limits)

Assume a hypothetical HOH phase‑out range from $X to $Y. If your MAGI is midway between, your direct contribution might be about 50% of the full limit. The calculator handles this math so you can focus on planning rather than formulas.

---

Coordination with Workplace Plans and HSAs

• 401(k)/403(b): Pre‑tax deferrals reduce AGI → may preserve Roth eligibility
• HSA: Pre‑tax contributions can lower MAGI for eligibility purposes
• Mega backdoor 401(k): not the same as Roth IRA; separate rules, sometimes complementary

---

Examples (Illustrative)

Example A: Single Filer Near Lower Phase‑Out Edge

• MAGI just above threshold → partial Roth allowed; the remainder can go to Traditional IRA (deductibility varies)
• Strategy: increase 401(k) deferral to drop beneath threshold and secure full Roth

Example B: MFJ Above Upper Phase‑Out Edge

• Direct Roth not allowed → use backdoor Roth flow
• Watch pro‑rata rule if you have pre‑tax IRA balances; consider rolling into a 401(k) first

Example C: HOH With Variable Income

• Bonus/RSU grants can push MAGI into phase‑out unexpectedly
• Plan timing of conversions, equity sales, and deductions to stay eligible

---

Backdoor Roth at a Glance

1. Make non‑deductible Traditional IRA contribution
2. Convert to Roth IRA (mind any gains and timing)
3. File Form 8606 to track basis
4. Avoid pro‑rata by eliminating pre‑tax IRA balances via plan roll‑ins where possible

---

Mistakes to Avoid

• Forgetting to file Form 8606 for basis tracking
• Triggering pro‑rata unexpectedly due to existing pre‑tax IRA assets
• Confusing Roth IRA income limits with Roth 401(k) rules (Roth 401(k) has no income limit)
• Racing to convert without considering market swings and wash sales in taxable accounts (not directly applicable to IRA, but sequence matters)

---

Frequently Asked Questions

Q: Do Roth IRA limits apply to Roth 401(k)?
A: No. Roth 401(k) has contribution limits independent of income.

Q: Is the backdoor Roth legal?
A: Yes, when executed correctly under current law; monitor legislative changes.

Q: What if my MAGI changes after I contributed?
A: Recharacterization/withdrawal options may be available—consult your custodian or tax advisor.

Action Checklist

• Compute MAGI and locate your filing status thresholds
• Decide direct Roth vs backdoor based on eligibility
• Adjust 401(k)/HSA to influence MAGI if needed
• Track basis and file required forms on time

Real‑World Case Studies (Illustrative)

Case 1: Tech Employee with RSUs

• RSU vests spike MAGI, pushing above the Roth phase‑out
• Tactics: increase 401(k), harvest losses, time stock sales; if still above → backdoor Roth

Case 2: Freelancer with Variable Income

• Year‑to‑year swings; some years allow full Roth, others require backdoor
• Tactic: project MAGI quarterly; pre‑emptively adjust deferrals to preserve eligibility

Case 3: Dual‑Income Couple

• One partner’s bonus creates phase‑out; combined MAGI exceeds limits
• Tactic: consider backdoor Roth and roll pre‑tax IRA into 401(k) to avoid pro‑rata

Documentation and Timing Notes

• Keep custodial confirmations for contributions, conversions, and recharacterizations
• File Form 8606 for each year you make nondeductible contributions or convert
• Align contributions with cash flow; avoid last‑minute errors near deadlines

---

Glossary

• AGI vs MAGI: MAGI adds back certain items to AGI for eligibility tests
• Pro‑Rata Rule: forces proportional taxation of conversions when pre‑tax IRA balances exist
• Backdoor Roth: nondeductible IRA contribution followed by Roth conversion

---

Timing and Market Considerations

• Contribute early to maximize time in market; if unsure on eligibility, use backdoor path with clean documentation
• If markets are volatile, small gains between contribution and conversion are normal; prompt conversion minimizes taxable growth
• Revisit eligibility after raises, bonuses, or equity vests; a mid‑year projection can save rework later

---

Coordination with Spousal IRAs

• Spousal IRAs allow contributions for a non‑working spouse if joint MAGI and earned income tests are met
• Ensure combined MAGI stays within thresholds for direct Roth; otherwise use backdoor for one or both spouses

---

Recordkeeping Best Practices

• Keep custodian confirmations for contributions, conversions, and any recharacterizations
• Maintain a permanent file of Form 8606s to track basis across years
• Label accounts clearly to avoid accidentally commingling pre‑ and post‑tax funds
