Roth Conversion vs. Roth Contribution: Two Very Different Strategies
A Roth contribution puts new money into a Roth IRA and is limited to $7,000 per year with income caps. A Roth conversion moves existing pre-tax money into a Roth IRA, no income limit, no dollar cap, but you pay income tax on every dollar converted. Nevada's 0% state income tax makes conversions uniquely affordable here.

These two strategies are frequently confused because both result in money inside a Roth IRA. But they operate under entirely different rules and serve different planning purposes. Understanding which is which, and when each applies, is essential for building the right strategy.
Roth IRA Contribution
A Roth contribution is new money you put into a Roth IRA from outside the account, typically from your paycheck or savings. You have already paid income tax on this money. You are now placing it into a Roth IRA where it will grow tax-free and be withdrawn tax-free in retirement.
- New money from earned income, goes into the account for the first time
- No income tax due in the year of contribution (money was already taxed)
- Annual limit: $7,000 in 2025 ($8,000 if age 50+)
- Income limit: phases out at $150,000–$165,000 (single) and $236,000–$246,000 (married filing jointly) in 2025
- Contributions (not earnings) can be withdrawn any time, penalty and tax free
Best for: Workers with earned income who fall below the income limits and want to build a tax-free retirement bucket year by year.
Roth Conversion
A Roth conversion moves existing pre-tax money, already sitting in a traditional IRA, 401(k), SEP IRA, or SIMPLE IRA, into a Roth IRA. You are repositioning existing retirement savings, not adding new money. The converted amount is added to your taxable income for the year of the conversion and taxed as ordinary income. In Nevada, only federal income taxes apply.
- No annual dollar limit, convert any amount you choose
- No income limit, available to anyone regardless of income
- Converted amount is taxable as ordinary income in the conversion year
- Nevada residents pay only federal income tax, zero state income tax
- Reduces future RMDs from traditional IRA accounts
Best for: Anyone with pre-tax retirement savings who wants to reduce future tax exposure, especially effective in low-income years and in Nevada where state tax savings are substantial.
Side-by-Side Feature Comparison
| Feature | Roth Contribution | Roth Conversion |
|---|---|---|
| Source of Money | New money from earned income, outside the IRA system | Existing pre-tax money already in a traditional IRA, 401(k), or similar account |
| Income Limits | Yes, phases out at $150K–$165K (single), $236K–$246K (married) in 2025 | None, anyone can convert regardless of income level |
| Annual Dollar Limit | $7,000 in 2025 ($8,000 if age 50+); cannot exceed earned income | No limit, convert $1 or $1,000,000 in the same year |
| Tax Impact in Conversion Year | None, money was already taxed before contribution | Converted amount added to ordinary income; taxed at your marginal rate |
| Nevada State Tax | 0% state tax (no new income created by a contribution) | 0% state tax on converted amount, only federal income tax applies |
| When It Makes Sense | Any year you have earned income and fall below income limits | Low-income years, early retirement, before RMDs begin, after a job change |
| Who Can Do It | Anyone with earned income below the income threshold; use backdoor strategy above limits | Anyone with a traditional IRA, 401(k), SEP IRA, or SIMPLE IRA balance |
Why Nevada Makes Roth Conversions Uniquely Cheap
The state you live in is one of the most important variables in the Roth conversion decision. Nevada's zero state income tax eliminates a major cost that residents of high-tax states must absorb.
The State Tax Cost of Conversion
When you convert $50,000 from a traditional IRA to a Roth IRA, that $50,000 is added to your ordinary income for the year. In a high-tax state, both federal and state income taxes apply to that $50,000:
- Nevada: Federal tax only. $0 state income tax on the conversion.
- California: Federal + up to 13.3% state, potentially $6,650 in state tax on that $50,000.
- Oregon: Federal + up to 9.9% state, potentially $4,950 in state tax on that $50,000.
- New York: Federal + up to 10.9% state, potentially $5,450 in state tax on that $50,000.
A Nevada resident in the 22% federal bracket who converts $50,000 pays $11,000 in federal income tax on the conversion. A California resident in the same federal bracket at a 9.3% state rate pays $11,000 federal plus $4,650 state, a total of $15,650. Nevada saves $4,650 on a single $50,000 conversion.
Low-Income Years Are Nevada Conversion Opportunities
The optimal time to execute a Roth conversion is when your taxable income is temporarily low, pushing that converted amount into the lowest available federal brackets. Nevada residents should actively identify these windows:
- Early retirement years before Social Security and RMDs begin (ages 60–72)
- Career transition or sabbatical years with lower earned income
- Years with large business losses or deductions that offset income
- Gaming and hospitality industry slowdowns with reduced hours or layoffs
Understanding the Rules for Each Strategy
Roth Contribution Rules in Detail
To make a direct Roth IRA contribution in 2025, your modified adjusted gross income (MAGI) must be below the phase-out thresholds: $150,000–$165,000 for single filers and $236,000–$246,000 for married filing jointly. Above those limits, direct Roth IRA contributions are not permitted.
High earners above the income limit can still access Roth IRA tax advantages through the backdoor Roth strategy: make a non-deductible traditional IRA contribution (no income limit), then immediately convert that contribution to a Roth IRA. The conversion is tax-free if no other pre-tax IRA balances exist (the pro-rata rule must be evaluated carefully).
Contributions must come from earned income. You cannot contribute more than your earned income for the year, and you cannot make contributions from Social Security, pension, or investment income alone.
Roth Conversion Rules in Detail
A Roth conversion has no income limit and no annual dollar cap. You can convert any amount from any eligible pre-tax account: traditional IRA, rollover IRA, SEP IRA, SIMPLE IRA (after 2 years of participation), or former employer 401(k) funds rolled into a traditional IRA first.
The converted amount is added to your ordinary income for the tax year of the conversion. Unlike traditional IRA withdrawals, there is no 10% early withdrawal penalty on a Roth conversion, even if you are under 59½, though the converted amount is fully taxable as income. However, if you withdraw converted funds from the Roth IRA within 5 years of the conversion and before age 59½, the 10% penalty may apply to those specific converted funds.
Strategically, most Nevada residents benefit from converting in annual increments that fill up, but do not exceed, a specific federal tax bracket rather than converting large amounts all at once.
Frequently Asked Questions
Yes. A Roth contribution and a Roth conversion are completely independent transactions. You can contribute $7,000 (or $8,000 if age 50+) directly to a Roth IRA and simultaneously execute a Roth conversion of any amount in the same tax year. The contribution counts against your annual IRA limit; the conversion does not affect that limit at all.
The only constraint is that the Roth IRA contribution is subject to income limits (phases out at $150,000–$165,000 for single filers in 2025), while the conversion has no income limit. Many Nevada residents use both strategies in the same year, making the maximum annual contribution while also converting a portion of their traditional IRA balance during a low-income period.
A backdoor Roth is technically both, it is a two-step process. Step one is a non-deductible contribution to a traditional IRA. Unlike a regular IRA contribution, non-deductible traditional IRA contributions have no income limit. Step two is converting that traditional IRA balance to a Roth IRA, this is the conversion step.
If your traditional IRA contains only after-tax (non-deductible) money and nothing else, the conversion is essentially tax-free because you already paid tax on that money. The pro-rata rule is the key risk: if you have other pre-tax traditional IRA balances, the IRS treats all your IRA funds as a pool and calculates the taxable portion of your conversion proportionally. Nevada residents doing backdoor Roth conversions benefit from the same 0% state income tax advantage on any taxable portion of the conversion.
No. Roth conversions do not count toward your annual IRA contribution limit. The $7,000 limit (2025) applies only to new money contributed from outside the IRA system, money you are putting into an IRA for the first time from a paycheck or savings account. A Roth conversion is a transfer of money already inside the retirement system from one account type (pre-tax) to another (Roth).
You can convert $100,000 from a traditional IRA to a Roth IRA and still make your full $7,000 Roth IRA contribution in the same year, as long as you meet the income requirements for the contribution. These are entirely separate transactions with separate rules.
The 5-year rules operate differently for contributions and conversions, and understanding the difference matters if you are accessing Roth funds before age 59½.
Contributions: There is one 5-year clock per person for Roth IRA contributions. It starts on January 1 of the first tax year you ever made any Roth IRA contribution, it never resets and applies to all your Roth IRAs combined. You must meet this 5-year holding period (along with being age 59½) for earnings to be distributed tax-free. Critically, Roth contribution principal can be withdrawn at any time, penalty and tax free.
Conversions: Each Roth conversion has its own separate 5-year clock. If you withdraw converted funds from your Roth IRA within 5 years of that specific conversion and you are under age 59½, the 10% early withdrawal penalty applies to the converted amount (no income tax, just the penalty). After age 59½, the 5-year conversion clock generally does not create penalty exposure, making it largely irrelevant for most conversion strategies focused on retirement planning.
