A Vanguard Traditional IRA is among the most popular choices for long-term retirement savers. The 2026 contribution limit is $7,000 ($8,000 if 50+) with no account minimum. Vanguard’s investor-owned structure means its ETF expense ratios average 0.05% — roughly one-fifth the industry average.

Who Can Deduct Traditional IRA Contributions?
Whether your contribution is tax-deductible depends on your income and whether you (or a spouse) are covered by a workplace retirement plan.
Covered by a workplace plan (2026):
| Filing Status | Full Deduction | Partial Deduction | No Deduction |
|---|---|---|---|
| Single or Head of Household | Up to $81,000 | $81,000–$91,000 | Over $91,000 |
| Married Filing Jointly | Up to $128,000 | $128,000–$148,000 | Over $148,000 |
Not covered by a workplace plan, but spouse is (2026):
| Situation | Full Deduction | Partial Deduction | No Deduction |
|---|---|---|---|
| Spouse covered by plan | Up to $236,000 | $236,000–$246,000 | Over $246,000 |
If neither you nor your spouse is covered by a workplace plan, your traditional IRA contribution is fully deductible regardless of income.

Best Vanguard Funds for a Traditional IRA

|---|---|---|---|
| VTI | ETF | 0.03% | Total US stock market (4,000+ stocks) |
| VOO | ETF | 0.03% | S&P 500 (500 largest US companies) |
| VXUS | ETF | 0.07% | Total international stock market |
| BND | ETF | 0.03% | Total US bond market |

Traditional IRA Tax Benefit: Worked Example
Scenario: 50-year-old, single, earns $78,000, covered by a 401(k) at work. Income is below the $81,000 threshold, so fully deductible:
- Contributes $8,000 to Vanguard Traditional IRA (catch-up eligible)
- Fully deductible — reduces taxable income by $8,000
- In the 22% bracket — saves $1,760 in federal taxes
- Invested in VTI at 0.03% ER for 15 years at 7% — grows to $22,078
Vanguard’s Limitation: No Fractional Shares
Vanguard does not offer fractional share investing. You must buy whole shares of ETFs. At current prices:
- VTI trades around $260/share
- A $7,000 IRA contribution buys 26 whole shares ($6,760) leaving $240 in cash
That $240 sits idle until you make another deposit. Fidelity and Schwab both offer fractional shares that allow full deployment of every dollar.
For a full discussion of Vanguard’s minimums and this limitation, see the Vanguard minimum investment guide.
Rolling a 401(k) Into a Vanguard Traditional IRA
Vanguard is one of the most popular 401(k) rollover destinations — particularly for investors who want to access Vanguard’s institutional index funds at retail prices. Direct rollovers avoid the 20% mandatory withholding on indirect rollovers.
See the Vanguard 401(k) rollover guide for complete step-by-step instructions.
Traditional IRA vs Roth IRA at Vanguard
Both accounts hold the same Vanguard funds — the difference is entirely in tax treatment:
| Feature | Traditional IRA | Roth IRA |
|---|---|---|
| Tax benefit | Deduction now, taxed on withdrawal | No deduction, tax-free withdrawal |
| RMDs | Yes (from age 73) | No RMDs during owner’s lifetime |
| Best if | High tax rate now, lower expected in retirement | Low tax rate now, higher expected later |
See the Vanguard Roth IRA guide for the Roth comparison.

Required Minimum Distributions begin at age 73. Vanguard provides:
