High-Earning Federal Employees Barred from Roth IRA Contributions
Federal tax changes in recent years have made Roth conversions more attractive for many employees. The Tax Cuts and Jobs Act lowered individual rates starting January 1, 2018. The One Big Beautiful Bill Act extended those lower rates through 2035.
Why Roth IRAs remain appealing
Roth IRA withdrawals that meet qualifying rules are not taxed as income. Contributions are made with after-tax dollars and earnings grow tax-free.
Roth accounts also avoid required minimum distributions. That feature can benefit retirement planning and tax flexibility.
2025 Roth IRA contribution limits and phase-out ranges
The IRS sets modified adjusted gross income phase-out ranges for Roth contributions. These ranges determine who may contribute directly.
| Filing Status | MAGI Phase-Out Range (2025) |
|---|---|
| Married filing jointly / Qualified surviving spouse | $236,000 – $246,000 |
| Single / Head of household | $150,000 – $165,000 |
| Married filing separate | $0 – $10,000 |
For 2025, the maximum traditional IRA contribution is $7,000. Those age 50 or older may contribute $8,000. The deadline to contribute for 2025 is April 15, 2026.
Back-door Roth IRA conversions explained
The back-door Roth IRA provides a route for those above the MAGI limits. High-earning federal employees barred from Roth IRA contributions can use this method.
The process is simple in steps. First, make a nondeductible contribution to a traditional IRA. Then convert that contribution to a Roth IRA.
Eligibility and paperwork
Contributors must have earned income in the year of the contribution. Each spouse may use the strategy if both have earned income.
Taxpayers must file IRS Form 8606 to report nondeductible traditional IRA contributions. This form notifies the IRS about after-tax basis in the IRA.
Timing and special rules
The back-door conversion works regardless of age. However, individuals at the required beginning date for RMDs must still take that year’s RMD.
Converted amounts count as Roth conversions, not Roth contributions. Those under age 59.5 must generally wait five years for penalty-free access to converted amounts.
The pro‑rata rule and tax consequences
The pro‑rata rule treats all traditional IRAs as a single account for conversion tax calculations. Rollover IRAs, SEP IRAs and SIMPLE IRAs are included.
That rule usually causes part of a conversion to be taxable. The taxable share depends on the ratio of pre-tax to after-tax IRA balances.
| Formula | Result |
|---|---|
| Tax-free portion | Converted amount × (after-tax IRA balance ÷ total IRA balance) |
| Taxable portion | Converted amount × (pre-tax IRA balance ÷ total IRA balance) |
Illustrative example
Jan is a single federal employee with MAGI of $200,000 in 2025. She cannot contribute directly to a Roth because her income exceeds the phase-out.
Jan contributes $7,000 as a nondeductible traditional IRA deposit. She also owns three IRAs: a $50,000 rollover IRA, a $40,000 SEP-IRA, and a $10,000 after-tax IRA.
Her total IRA balance is $100,000. The after-tax portion equals $10,000. Therefore only 10 percent of any conversion is tax-free.
- Tax-free portion: $7,000 × ($10,000 ÷ $100,000) = $700.
- Taxable portion: $7,000 × ($90,000 ÷ $100,000) = $6,300.
Avoiding pro‑rata taxation using the TSP
Federal employees with pre-tax traditional IRAs can move those funds into their traditional TSP. Doing so reduces pre-tax IRA balances for pro‑rata calculations.
If Jan transferred her $50,000 rollover IRA and $40,000 SEP-IRA into the TSP first, her IRA would show only the $10,000 after-tax balance. The conversion would then be fully tax-free.
Transfers into the traditional TSP can usually be requested online through the TSP account portal.
Practical considerations
IRS Publication 590-A includes worksheets to help calculate phase-outs and limits. The publication is available on the IRS website.
Conversions can create tax liabilities. Consult a tax professional before converting. A tax advisor can suggest steps to minimize taxes.
