Traditional IRA: rules, costs and examples

By IRACircle · Updated 2026-10-21 · AI-assisted education

Overview

A Traditional IRA is a personal retirement account. The account provides tax treatment; the investments you choose determine investment risk. A contribution can be allowed even when the contribution is not deductible. Keeping these two questions separate prevents a common mistake: assuming an employer retirement plan stops you from having an IRA at all.

Who is this for?

Start with three facts: your taxable compensation, your filing status, and whether you or your spouse participates in a workplace retirement plan. A saver considering a deduction should check the applicable income worksheet before depositing money. If a deduction is unavailable, compare a Roth contribution, a nondeductible Traditional contribution with basis tracking, and other saving options rather than assuming one account is automatically best.

Tax treatment

An allowed deduction reduces current taxable income. Investment income generally remains untaxed while inside the account, and taxable distributions are ordinary income. Nondeductible contributions create basis rather than a second deduction. Preserve Form 8606 records across years and custodians. A custodian receiving your account does not necessarily receive your complete tax-basis history.

Contribution rules

For 2026, the combined regular Traditional and Roth IRA limit is $7,500, or $8,600 if age 50 or older by year end, limited by eligible compensation. It is one shared limit across custodians. For a single filer covered at work, the deduction phase-out is $81,000–$91,000 of modified AGI; for a jointly filing contributor covered at work, it is $129,000–$149,000. Different rules apply when only a spouse is covered, or when filing separately. Use the IRS worksheet for your status.

Investments and costs

Ask the custodian which investments and account fees apply. A low account-opening charge does not reveal fund expenses, transfer charges, or the interest paid on idle cash. Compare the cost of your intended portfolio, including cash, rather than a promotional headline. Holding an investment in an IRA does not insure it against market loss.

Withdrawals and restrictions

Taxable withdrawals before age 59½ generally also face a 10% additional tax unless an exception applies. A penalty exception does not itself make the withdrawal income-tax-free. Required minimum distributions depend on birth year: the starting age is generally 73 for people born 1951–1959 and 75 for those born in 1960 or later. Beneficiary rules are separate.

Worked example and decision checklist

Hypothetical deduction example: an eligible $4,000 deduction at a 22% marginal federal rate reduces that year’s federal tax by $880, assuming the deduction stays within that bracket. That is a current tax saving, not a guaranteed lifetime advantage. Compare the tax cost of future withdrawals and state treatment. Before converting to Roth, inventory all Traditional, SEP, and SIMPLE IRA balances and nondeductible basis; account labels alone do not isolate basis.
