Short answer
The core difference is when the tax benefit shows up.
IRS Roth IRA rules center on after-tax contributions and qualified distributions. For 2026, IRS lists the IRA contribution limit at $7,500 and the Roth IRA joint-filer phase-out range at $242,000 to $252,000.

In real life: This can make the same claiming age feel different for someone still earning a paycheck.
