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

Fund Type Expense Ratio What It Covers
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
VTSAX Mutual Fund 0.04% Total Stock Market Admiral ($3,000 min)
VBTLX Mutual Fund 0.05% Total Bond Market Admiral ($3,000 min)

The three-fund portfolio — VTI + VXUS + BND in proportions matching your risk tolerance — provides complete global diversification at an average expense ratio well under 0.10%.

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.

RMDs at Vanguard

Required Minimum Distributions begin at age 73. Vanguard provides:

  • Online RMD calculator with your balance pre-loaded
  • Automatic RMD service — Vanguard calculates and distributes annually
  • Transfer to taxable Vanguard account, check by mail, or direct bank deposit
