IMPORTANT — the Roth qualified distribution test: A Roth distribution is tax-free only if the 5-year holding period is met AND one of: age 59½, death, disability, or first-time home purchase (up to a lifetime limit). Contributions (not earnings) can always be withdrawn tax- and penalty-free.

Early distribution penalty

Distributions before age 59½ generally incur a 10% additional tax on top of ordinary income tax. Exceptions include: death, disability, qualified higher education expenses, first-time home purchase (IRAs, limited), substantially equal periodic payments, medical expenses above the AGI threshold, and a qualified birth or adoption.

Employer plans

  • 401(k) — elective deferrals reduce taxable wages (but not Social Security/Medicare wages); employer matches are not currently taxable
  • SEP — employer-funded, useful for self-employed taxpayers
  • SIMPLE — for small employers, with mandatory employer contributions
  • Defined benefit — promises a specified benefit; employer bears the investment risk

EXAM TIP: A direct trustee-to-trustee rollover avoids withholding entirely. An indirect (60-day) rollover from an employer plan triggers mandatory 20% withholding, and the taxpayer must replace that withheld amount from other funds to roll over the full balance.
