Curious if a Roth conversion might boost your Social Security benefits? Here’s the reality: while converting to a Roth IRA ramps up your taxable income for that year, it doesn’t affect the way Social Security calculates your benefits. Social Security relies solely on your earned income, not the extra taxable income generated by a Roth conversion. So even though you’ll pay taxes on the conversion, it won’t add any extra credits to your Social Security record. In fact, Roth conversions can add costs in other retirement areas, as well, despite their advantages. Here are some more things to consider for your retirement planning.

Roth Conversions and Taxable Income
A Roth conversion is when you move money from a pre-tax portfolio, like a 401(k) or an IRA, and put it into a Roth IRA. You can only move money from a pre-tax portfolio, not a depository account or a taxed investment account. However, within this restriction, there is no limit to how much money you can convert in a given year.
The advantage to a Roth conversion is that you will receive the full benefits of a Roth IRA. This means your money will grow tax-free and, when you withdraw it, you won’t pay any taxes on those withdrawals. A Roth account is also exempt from required minimum distributions (RMDs), and qualified withdrawals do not count toward your taxable income in a given year.
The disadvantage to a Roth conversion is that the entire amount converted counts toward your taxable income for the year. For example, say you earned $75,000 in salary and converted $100,000 to your Roth IRA in the same calendar year. Your total taxable income for that year would be $175,000.
For any Roth conversion, you need to make sure you have the cash on hand to pay the additional income taxes that this conversion will trigger. If you’re over 59 ½ years old, you can take the money from your retirement fund. Otherwise, you need the cash on hand from other sources.
This will also affect any other programs that measure your taxable income. For example, your Social Security benefit taxes and Medicare premiums might increase, since both are based on your taxable income. This also could affect some student aid programs, if you have a child in school or are in school yourself, or it might change your eligibility for Medicaid.
In this case, if you convert $50,000 per year you should plan for these fluctuations. A $50,000 increase in your taxable income will significantly increase your income taxes for the year, and will almost certainly affect any income-assessed programs. Unless you are already at the top of the range, for example, your Medicare premiums will definitely go up, and your Social Security benefit taxes too. Make sure you plan for that.
Any income-related fluctuations will be temporary, since conversion taxes only apply to the year in which you made the conversion. In our case above, for example, the following year your income would be $75,000 again. However it’s important to prepare for the full impact of spiking your taxable income, even if just temporarily.
A financial advisor can help you navigate taxes and execute an appropriate strategy.
Social Security Credits
Social Security benefits are based on a credit system. During your working life, you receive credits from the Social Security Agency for all income earned each year. The SSA tracks these on an annual basis. That is, you receive credits for all earned income in 2025, then a separate set of credits for all earned income in 2026, and so on.
You receive credits up to the maximum earnings that are eligible for Social Security taxes. Any income above this level does not generate additional credits. In 2026, this maximum is $184,500.
Your Social Security benefits in retirement are based on these credits earned during your working life. When you retire, the Social Security Agency averages the credits you earned during your 35 highest-earning years. Your benefits are then calculated based on this average.
Earned Income vs. Taxable Income
As noted above, there is a critical difference between the income associated with Roth conversions and Social Security credits.
Roth conversions increase your taxable income for a given year. This is defined as the amount of income potentially eligible for federal, state and local taxes, regardless of the source. Note that it doesn’t necessarily mean that amount of income on which you do pay taxes, given deductions, exclusions and other exemptions. It’s just the amount which could be eligible for taxation.

About This Calculator
Our income tax calculator calculates your federal, state and local taxes based on several key inputs: your household income, location, filing status and number of personal exemptions.
How Income Taxes Are Calculated
-
First, we calculate your adjusted gross income (AGI) by taking your total household income and reducing it by certain items such as contributions to your 401(k).
-
Next, from AGI we subtract exemptions and deductions (either itemized or standard) to get your taxable income. Exemptions can be claimed for each taxpayer.
-
Based on your filing status, your taxable income is then applied to the tax brackets to calculate your federal income taxes owed for the year.
-
Your location will determine whether you owe local and / or state taxes.
When Do We Update? - We check for any updates to the latest tax rates and regulations annually.
Customer Service - If you would like to leave any feedback, feel free to email info@smartasset.com.
Assumptions
Deductions
- "Other Pre-Tax Deductions" are not used to calculate state taxable income.
Credits
- The only federal credit automatically calculated is the Savers Credit, depending on your eligibility.
- We do not apply any refundable credits, like the Child Tax Credit or Earned Income Tax Credit (EITC).
- We do not apply state credits in our calculations.
Itemized Deductions
- If itemizing at the federal level, you may need to itemize at the state level too. Some states don't allow itemized deductions, which is accounted for in our calculations.
- When calculating the SALT deduction for itemized deductions, we use state and local taxes, and we assume your MAGI.
- We assume that there is no cap to itemized deductions, if a state allows them.
- We do not categorize itemized deductions (such as medical expenses or mortgage interest), which could be subject to specific caps per state.
Local Tax
- Depending on the state, we calculate local taxes at the city level or county level. We do not include local taxes on school districts, metro areas or combine county and city taxes.
- With the exception of NYC, Yonkers, and Portland/Multnomah County, we assume local taxes are a flat tax on either state taxable income or gross income.

Earned income, on the other hand, is money that you receive for work. There are a few statutory examples of earned income as well, for example strike benefits or disability pay. In general, this means money received as payment for a job, earnings from self-employment and profits from running a business. Most significantly, it does not include money you receive from investments or other portfolios.
Earned income is, in almost all cases, taxable income. However, not all taxable income is earned income. This is where the distinction comes in here. A Roth conversion uses money taken from a pre-tax retirement portfolio. Although it applies to your taxable income for the year, it is not considered earned income. As a result, a Roth conversion will not affect your potential Social Security benefits, no matter how much money you move.
Consider speaking with a financial advisor about your financial goals.
Bottom Line
Roth conversions cannot increase your Social Security benefits. A Roth conversion increases your taxable income, while Social Security credits are assessed based on your earned income. While Roth conversions can increase the taxes you pay on benefits if you make a conversion in retirement, they cannot increase your benefits themselves.
Retirement Planning Tips
- Just because a Roth conversion can’t increase your Social Security benefits, that doesn’t mean it can’t be done. In fact, here are four tips on how you can plan to boost your benefits in retirement.
- Finding a financial advisor doesn’t have to be hard. SmartAsset’s free tool matches you with vetted financial advisors who serve your area, and you can have a free introductory call with your advisor matches to decide which one you feel is right for you. If you’re ready to find an advisor who can help you achieve your financial goals, get started now.
- Keep an emergency fund on hand in case you run into unexpected expenses. An emergency fund should kept in an account that isn’t at risk of significant fluctuation like the stock market. The tradeoff is that the value of liquid cash can be eroded by inflation. But a high-interest account allows you to earn compound interest. Compare savings accounts from these banks.
