Quick Answer
Roth IRA: contribute after-tax dollars, withdraw completely tax-free in retirement — favors lower tax brackets now. Traditional IRA: deduct contributions from taxable income now, pay taxes at withdrawal — favors higher brackets now than expected in retirement. Both accept ITIN at Fidelity and Schwab.
What Is the Core Difference Between a Roth and Traditional IRA?
The core difference between a Roth and Traditional IRA is when you pay taxes. A Roth uses after-tax dollars and grows tax-free, while a Traditional may be deductible now but is taxed on withdrawal. Both share the same 2026 limit of $7,500 and can hold the same stocks, bonds, and index funds. Only the timing of the tax differs.
| Roth IRA | Traditional IRA | |
|---|---|---|
| Contributions | After-tax dollars (no deduction) | May be tax-deductible (reduces income now) |
| Growth | Tax-free | Tax-deferred |
| Withdrawals in retirement | Tax-free (qualified) | Taxed as ordinary income |
| Early withdrawal of contributions | Contributions can be withdrawn anytime, penalty-free | 10% penalty + taxes before age 59½ (with exceptions) |
| RMDs (Required Minimum Distributions) | None during owner's lifetime | Required starting at age 73 |
| Income limit to contribute | Phase-out above $153,000 (single, 2026) | No income limit to contribute; deductibility may be limited |
What Are the 2026 IRS Contribution Limits for IRAs?
The 2026 IRS contribution limit for IRAs is $7,500 if you are under 50 and $8,600 if you are 50 or older, which includes a $1,100 catch-up. That limit is the combined total across all your Roth and Traditional IRAs — you cannot put $7,500 in each. Roth contributions also phase out above $153,000 for single filers.
These figures come from IRS Notice 2025-67 and apply to the 2026 tax year.
Contribution Limits (Both Roth and Traditional Combined)
- Under age 50: $7,500
- Age 50 and older: $8,600 (includes $1,100 catch-up)
- This is your total across all IRAs — you cannot contribute $7,500 to a Roth AND $7,500 to a Traditional in the same year
Roth IRA Income Phase-Out (2026)
- Single / Head of Household: Full contribution below $153,000; phased out $153,000–$168,000; no direct contribution above $168,000
- Married Filing Jointly: Full contribution below $242,000; phased out $242,000–$252,000
Traditional IRA Deductibility Phase-Out (2026, if covered by a workplace plan)
- Single: Full deduction below $81,000; phased out $81,000–$91,000; no deduction above $91,000
- Married Filing Jointly (active participant): Full deduction below $129,000; phased out $129,000–$149,000
- Not covered by a workplace plan: Deduction is always available regardless of income
Note: You can still contribute to a Traditional IRA even if the deduction is not available — the money grows tax-deferred. This is sometimes called a "non-deductible Traditional IRA."
When Is the Roth IRA Usually Better?
The Roth IRA is usually better when your tax rate today is lower than your expected rate in retirement — common for workers under $80,000 to $100,000 who expect their income to grow. Roth contributions can also be withdrawn at any age penalty-free, and the account carries no required minimum distributions during your lifetime.
- You're early in your career with relatively low income
- You expect your income and tax bracket to grow over time
- You value flexibility — Roth contributions (not earnings) can be withdrawn at any age without penalty, which makes the account useful as a secondary emergency fund for serious situations
- You want to avoid RMDs in retirement — Roth IRAs have no required minimum distributions during your lifetime
- You're uncertain about future tax rates and want to diversify (having both pre-tax and Roth accounts gives you flexibility in retirement)
For most ITIN holders: If you're earning under $80,000–$100,000 and building wealth, the Roth is generally the recommended starting point. The tax-free growth over 20–40 years is a substantial advantage.
When Is the Traditional IRA Usually Better?
The Traditional IRA is usually better when your tax rate today is higher than you expect in retirement, which is common in a peak earning year. For 2026, the deduction is fully available if you are not covered by a workplace plan, and it can lower your current taxable income now while the money grows tax-deferred until withdrawal.
- You're in a peak earning year and want to reduce your current taxable income
- You expect lower income (and thus a lower tax bracket) in retirement
- You are not covered by a workplace retirement plan (the deduction is fully available)
- You're above the Roth income phase-out limit and want to contribute to an IRA (via the "backdoor Roth" strategy — consult a tax professional for this)
What Should I Do If My Income Falls Between Roth and Traditional?
If you earn roughly $60,000–$120,000 as a single filer, the Roth vs. Traditional decision involves genuine uncertainty — you don't know exactly what tax rates will be in 20–30 years, and your future retirement income is hard to predict.
A practical approach many financial planners suggest for this income range:
- If your employer offers a 401(k), use the pre-tax 401(k) for the employer match, then contribute to a Roth IRA for your personal retirement savings. This gives you both pre-tax and Roth accounts in retirement.
- Having money in both types of accounts in retirement gives you tax flexibility — you can pull from pre-tax accounts in low-income years and Roth accounts in higher-income years.
Can ITIN Holders Contribute to Both?
Yes — you can have both a Roth IRA and a Traditional IRA in the same year, but your total combined contributions cannot exceed the annual limit ($7,500 for under 50 in 2026). For example, you could put $5,000 in a Roth and $2,500 in a Traditional, as long as the total is $7,500 or less.
Frequently Asked Questions
Can ITIN holders contribute to a Roth IRA or Traditional IRA?
Yes. ITIN holders can open and contribute to both types at brokerages that accept ITIN holders (Fidelity and Schwab). You must have earned income at least equal to your contribution. The IRS does not require an SSN — your ITIN satisfies the taxpayer identification requirement.

$7,500 for individuals under 50; $8,600 for age 50 and older. This applies to your combined contributions across all IRA accounts in the same year. Source: IRS Notice 2025-67.
What is the income limit for a Roth IRA in 2026?
Full Roth contribution below $153,000 (single) / $242,000 (married filing jointly). Phase-out ranges: $153,000–$168,000 (single) and $242,000–$252,000 (MFJ). No direct Roth contribution above the upper limit. Source: IRS Notice 2025-67.
When should an ITIN holder choose a Roth IRA?
When your current tax rate is lower than you expect in retirement; when you want tax-free growth and withdrawals; when you want flexibility to withdraw contributions without penalty; or when you want to avoid Required Minimum Distributions. Most ITIN holders earning under $80,000–$100,000 early in their careers are good Roth candidates.
When should an ITIN holder choose a Traditional IRA?
When you're in a higher tax bracket now and expect a lower one in retirement; when you want to reduce current taxable income; or when your income exceeds the Roth phase-out. Remember the deduction is only available if you're not covered by a workplace plan, or if your income falls below the deductibility phase-out ($81,000–$91,000 single for 2026).
