Direct Answer
Complete eligibility and deduction checks before comparing tax rates. Then document the assumptions that would make Roth or Traditional more attractive. Re-run this checklist each year because MAGI, workplace coverage, filing status, account balances, and tax rules can change.
Roth vs Traditional IRA Decision Checklist
This checklist walks through the Roth-versus-Traditional IRA decision in eight sections: eligibility, deductibility, current marginal tax rate, future tax rate, contribution-cap economics, flexibility, household coordination, and the decision record. Complete each section in order before comparing accounts.
A. Contribution Eligibility
- I have enough taxable compensation, or a valid spousal IRA rule applies.
- I know my expected 2026 MAGI range.
- I checked whether a full, partial, or no direct Roth contribution is allowed.
- I understand that the 2026 limit of $7,500, or $8,600 for those age 50 and older, is combined across Roth and Traditional IRAs.
B. Traditional IRA Deduction
- I know whether I am covered by a workplace retirement plan.
- I know whether my spouse is covered by a workplace plan.
- I checked the 2026 Traditional deduction phase-out for my filing status and coverage situation.
- I know whether my planned Traditional contribution would be full-deduction, partial-deduction, or nondeductible.
- If nondeductible, I understand that Form 8606 basis reporting can apply.

C. Current Tax-Rate Assumptions
Record the rates you are using in this analysis:
- Current marginal federal rate: ___________
- Current marginal state rate: ___________
- Combined rate used in model: ___________
- I used my marginal tax rate, not my average effective tax rate.
- If the deduction crosses a bracket boundary, I modeled the split correctly.
D. Future Tax-Rate Assumptions
Record the range you consider plausible for future combined marginal rates: ___________ to ___________
Note why that range is plausible for your situation.
- I considered pension income expectations.
- I considered taxable Social Security income.
- I considered future required minimum distributions (RMDs) from pre-tax accounts.
- I considered retirement state income tax treatment.
- I considered a surviving-spouse single-filer scenario if relevant.
- I did not assume that future tax law is certain.
E. Contribution-Cap Economics
- I am or am not likely to max the IRA this year.
- Roth income tax would or would not be paid from money held outside the account.
- Traditional tax savings would be: invested, placed in HSA, applied to debt payoff, held in emergency reserve, spent, or other.
- My comparison uses: equal nominal contribution, equal pre-tax household cost, or both bases.
F. Flexibility Factors
Rate each factor as Low, Medium, or High importance for your situation:
| Factor | Importance |
|---|---|
| Access to regular Roth contribution principal before retirement age | Low / Medium / High |
| No lifetime Roth IRA required minimum distribution for original owner | Low / Medium / High |
| Future Roth conversion opportunity from Traditional IRA | Low / Medium / High |
| Qualified charitable distribution planning from Traditional IRA | Low / Medium / High |
| Survivor and estate tax flexibility | Low / Medium / High |
| Preference for simpler future tax character of withdrawals | Low / Medium / High |
G. Household Coordination
- Employer match has been considered, including whether the match requires a specific contribution type.
- The existing Traditional versus Roth balance in workplace plans (401(k), 403(b)) is included.
- Spouse accounts and their pre-tax versus after-tax character are included.
- Existing Traditional, SEP, and SIMPLE IRA balances are known before any backdoor Roth plan, because of the pro-rata rule.
- Taxable investment accounts and emergency reserves are considered in the overall picture.
- Pension income expectations are included.
- Planned retirement state is included if its income tax treatment of IRA withdrawals differs materially.
- Estate and beneficiary objectives are included if material to the account-type choice.

Stop Signs: Resolve These Before Acting
If any of the following applies, resolve the underlying rule or uncertainty before making a contribution, conversion, or rollover decision:
- Expected MAGI is close to a Roth or Traditional phase-out boundary.
- I cannot determine whether the Traditional contribution is deductible.
- I have prior nondeductible IRA contributions but cannot locate my Form 8606 records.
- I am considering a backdoor Roth and I hold substantial pre-tax Traditional, SEP, or SIMPLE IRA balances.
- A Roth conversion could materially affect another tax threshold or means-tested benefit.
- The tax dollars involved are large enough that professional review is prudent.
If any stop sign applies, the correct next step is to resolve the specific rule or uncertainty, not to arrive at an account verdict before the facts are clear.
