A traditional IRA contribution may be deductible if the taxpayer qualifies, while a Roth IRA contribution is not deductible and qualified Roth IRA distributions are not included in income. For 2026, the IRS says combined traditional and Roth IRA contributions generally cannot exceed $7,500, or $8,600 for age 50 or older, subject to taxable compensation and Roth income limits.
What roth ira vs traditional ira means
A traditional IRA can offer a current deduction when eligibility rules are met; a Roth IRA uses after-tax contributions and has separate income eligibility rules. This compares personal IRAs; a Roth 401(k) is an employer-plan account with different plan access and limits.

Roth IRA vs. traditional IRA: deduction now or qualified withdrawals later?: worked numbers
A 35-year-old with $7,500 of taxable compensation allocates $4,000 to a traditional IRA and $3,500 to a Roth IRA. The combined contribution is $7,500, not $11,000. Whether the $4,000 traditional contribution is deductible depends on filing status, income, and workplace-plan participation; whether the Roth $3,500 is allowed depends on modified AGI.

Common mistakes
Do not give each IRA its own full annual limit, assume a traditional contribution is always deductible, or use gross pay instead of the tax return's relevant compensation and modified AGI measures.
Where the calculation stops
Contribution year, filing status, spouse rules, rollovers, conversions, early distributions, and state taxation need individual verification.
