Traditional IRA Deduction Limits 2026

Updated October 2026 · About 5 min read

A traditional IRA deduction sounds universal and is not: a saver covered by a workplace 401(k) loses the deduction entirely above roughly $90,000 single or $153,000 joint in 2026. Contribute $7,000 anyway and it becomes a nondeductible contribution — tax-deferred growth with after-tax principal, the least efficient flavor of IRA there is.

Why Nondeductible Contributions Underperform

A nondeductible traditional IRA grows tax-deferred, but withdrawals split: the principal portion comes back tax-free, the growth is ordinary income. Compare with a taxable brokerage: same after-tax principal, but growth gets long-term capital gains rates of 0/15/20% instead of ordinary rates up to 37%, plus a step-up in basis at death. For most savers above the deduction limits, taxable investing beats a nondeductible IRA — unless the balance is destined for a backdoor Roth conversion, which is precisely the one strategy that makes nondeductible money valuable.

The Better Routes Above the Limits

Savers with a workplace plan above the phase-out should usually prioritize: more 401(k) deferral, then an HSA where eligible, then the backdoor Roth. Form 8606 matters the moment any nondeductible contribution exists — it establishes basis, prevents double taxation years later, and feeds the pro-rata calculation that decides backdoor conversion tax. Skipping the form has stranded millions of deductions over the decades; the IRS has no obligation to reconstruct your basis for you.

Above the phase-out, the same $7,000 works harder almost anywhere else.
