Individual Retirement Accounts (IRAs)

IRAs remain the backbone of personal retirement savings, and Series 66 questions regularly test how contribution limits, tax treatment, and income phase-outs interact. Use the current-year thresholds below; 2026 data reflects Notice 2025-67 (IRS, Nov. 13, 2025).


Contribution Limits (2026)

  • Under age 50: $7,500 combined across all Traditional + Roth IRAs
  • Age 50 or older: $8,600 (includes the $1,100 catch-up now indexed under SECURE 2.0)
  • Contributions cannot exceed the taxpayer’s earned income for the year
  • Spousal IRAs are permitted when filing jointly as long as combined earned income covers both contributions

Traditional IRA

Key traits:

  • Contributions may be tax-deductible depending on income and employer plan coverage
  • Earnings compound tax-deferred; all distributions are taxed as ordinary income
  • Anyone with earned income can contribute, but deductibility phases out for higher earners covered by workplace plans
  • RMDs begin at age 73 (moves to 75 for those born in 1960 or later per SECURE 2.0)
  • 10% penalty applies to pre-59.5 distributions unless an IRA-specific exception applies (death, disability, first-time home purchase up to $10k, qualified education, SEPP/72(t), etc.)

2026 deductibility phase-out ranges (Modified Adjusted Gross Income):

Filing StatusCovered by Employer Plan?Full DeductionPhaseout RangeNo Deduction
Single / Head of HouseholdYes$81,000 or less$81,000 - $91,000Above $91,000
Married Filing JointlyContributor covered$129,000 or less$129,000 - $149,000Above $149,000
Married Filing JointlyContributor not covered, spouse is$242,000 or less$242,000 - $252,000Above $252,000
Married Filing JointlyNeither spouse coveredFull deduction at any incomeN/AN/A
Married Filing Separately (MFS)*Contributor coveredNot available$0 - $10,000Above $10,000
  • If neither spouse is covered by a workplace plan, the contribution stays fully deductible regardless of income.
  • Above the phase-out ceiling a taxpayer can still make a non-deductible contribution (Form 8606 tracks basis).
  • MFS taxpayers who lived apart from their spouse the entire year use the Single / HOH thresholds instead of the $0 - $10,000 band.

Exam Tip: Gotchas

Deductibility, not contribution eligibility, is what phases out for Traditional IRAs. This distinction is a favorite Series 66 trick question.


Roth IRA

Key traits:

  • Contributions are made with after-tax dollars (never deductible)
  • Qualified distributions (5-year clock + age 59.5/death/disability/first-time home) are completely tax-free
  • No RMDs for the original owner, making Roth IRAs a core estate-planning tool
  • Contributions (principal) can be withdrawn anytime tax- and penalty-free under ordering rules

2026 Roth contribution eligibility (MAGI):

Filing StatusFull ContributionPhaseout RangeNo Contribution
Single / Head of HouseholdBelow $153,000$153,000 - $168,000$168,000 or more
Married Filing JointlyBelow $242,000$242,000 - $252,000$252,000 or more
Married Filing Separately (MFS)*Not available$0 - $10,000Above $10,000
  • MFS taxpayers who lived apart from their spouse the entire tax year follow the Single / HOH thresholds.

Exam tip: Roth contributions have income limits; Roth conversions do not. Watch for questions mixing the two.

Roth Conversion (aka "Backdoor Roth")

  • Any taxpayer can convert Traditional IRA dollars to a Roth IRA regardless of income level.
  • The converted amount is taxed as ordinary income in the conversion year; no 10% penalty if assets transfer trustee-to-trustee.
  • Conversions restart the 5-year clock for penalty-free access to converted principal.
  • Strategically helpful for clients expecting higher future tax brackets or seeking to remove future RMDs.

Exam Tip: Gotchas

The pro-rata rule applies. If a client owns pre-tax and after-tax IRA dollars, each conversion or distribution is treated as proportional slices of both.
