Why You Should Convert to Roth Before Claiming Social Security

Timing is everything — especially when it comes to Roth IRA conversions and Social Security. Convert too late, and you might trigger unnecessary taxes on your retirement income, including your Social Security benefits.

In this article, we’ll explain exactly why it’s so important to complete your Roth conversions before claiming Social Security, with real-life examples and a strategy summary you can follow.

1. What Is a Roth IRA Conversion?

A Roth IRA Conversion moves pre-tax money from a Traditional IRA or 401(k) into a Roth IRA. You’ll pay income tax on the converted amount now, but once inside the Roth, that money grows tax-free and can be withdrawn tax-free later.

So why not convert anytime? Because the timing of your conversion affects other taxes — especially Social Security and Medicare premiums.

2. The Social Security Tax Trap

Your Social Security benefits may be partially taxable depending on how much other income you have.

Combined Income = Other Income + 50% of Social Security

✔️ Below the first threshold → 0% taxable
✔️ Between thresholds → up to 50% taxable
✔️ Above the second threshold → up to 85% of your benefits are taxable

Important: Roth conversions count as income. So if you convert after you start receiving Social Security, you may cause your benefits to be taxed.

3. Example: Conversion After Social Security Starts

Scenario:

• Filing Status: Married Filing Jointly
• Social Security: $42,000/year
• Roth Conversion: $30,000
• Other Income: $6,000 (interest/dividends)

Combined Income = $30,000 + $6,000 + 50% of $42,000 = $57,000 → Well above the $44,000 threshold → 85% of Social Security becomes taxable

Your “tax-free” Roth strategy just triggered a major tax bill.

4. Why Convert Before Claiming Social Security?

By converting earlier — ideally between retirement and age 62 — you avoid:

• Taxing up to 85% of your Social Security
• Increasing MAGI and triggering IRMAA (Medicare surcharges)
• Wasting your low-income window between retirement and Social Security

5. Realistic Example: Convert Early, Save Thousands

✅ Before Claiming Social Security

• Age: 60
• Filing Status: Married Filing Jointly
• Roth Conversion: $35,000
• Other Income: $5,000
• Social Security: Not yet claimed

Use standard deduction ($29,200 in 2025) → Only $10,800 is taxable No Social Security in play → No impact → Tax-efficient conversion

❌ After Claiming Social Security

• Age: 66
• Same Roth Conversion: $35,000
• Social Security: $42,000
• Other Income: $6,000

Combined Income = $35,000 + $6,000 + $21,000 = $62,000 → 85% of SS taxable (~$35,700) → Total taxable income = ~$76,700 → Pushed into higher tax brackets

6. Bonus: Avoid Medicare IRMAA by Age 63

Medicare uses your income from 2 years ago to calculate premiums. If you convert after age 63, you may trigger IRMAA when you turn 65.

✅ Converting before age 63 helps avoid IRMAA penalties at 65.

7. Strategy Summary

Final Thoughts

Roth conversions are powerful — but only if timed right. Don’t wait until after Social Security starts. Convert during your low-income years before age 63 to:

• Reduce lifetime taxes
• Protect Social Security
• Avoid IRMAA
• Maximize tax-free income

Now is your opportunity. Use it wisely.
