Roth IRA vs Traditional IRA 2026: Which to Fund First?

Both Roth and Traditional IRAs let you save $7,000 a year ($8,000 if you are 50+) in 2026, but they flip the tax timing: Traditional gives you a deduction now and taxes withdrawals later, while Roth is funded with after-tax dollars and pays out tax-free in retirement. The right pick depends almost entirely on whether your marginal tax rate today is higher or lower than what you expect in retirement, with extra wrinkles for high earners.

Our Verdict

If you are under 40 or in the 12-24% bracket, fund the Roth IRA first — you lock in today’s historically low rates and get decades of tax-free compounding plus RMD-free flexibility. If you are a peak-earner in the 32-37% bracket expecting to retire into a lower bracket, the Traditional IRA (or deductible 401(k)) wins the math. The ideal split for most households: max a Roth IRA ($7k) for tax diversification, then pile the rest into the pre-tax 401(k); high earners over the Roth phase-out should run a backdoor Roth every January.
