FPSB Retirement & Tax Specialist common mistakes
FPSB Retirement & Tax Specialist · Understand the traps and how to avoid them.
Treating the retirement-account contribution limits as one shared number and applying the same cap to every account type (traditional IRA, Roth IRA, employer plan), instead of separating the employee-deferral limit, the combined employer-plus-employee limit, and the IRA limit.
Candidates memorise a single headline figure from the prior year and reuse it across account types, and they forget that catch-up contributions sit on top of the base limit rather than inside it.
What to do instead
Build a one-page limit table with one row per account type and one column per year, and on every practice question write down which limit the question is actually testing before computing. Re-verify figures against the current-year official source, since limits are indexed annually.
Calculating the retirement plan contribution deduction without first checking whether the taxpayer is an active participant and what their modified adjusted gross income is, so the phase-out is skipped entirely.
The active-participant flag is buried in a W-2 box or an employer statement, and candidates jump to the arithmetic before establishing eligibility.
What to do instead
Adopt a fixed sequence for every deduction question: (1) is the person an active participant, (2) what is filing status, (3) what is MAGI, (4) apply the phase-out range, (5) only then compute the deductible amount. Practise the sequence until it is automatic.
Confusing the Roth IRA contribution income phase-out with the Roth conversion rules, and applying an income limit to a conversion that has none.
Both involve Roth accounts and both involve income, so the two rule sets blur together under time pressure.
What to do instead
Write a two-column comparison card: contributions (income limits apply, annual cap applies) versus conversions (no income limit, no annual cap, taxable in the year of conversion). Recite the card before attempting any Roth question.
Applying the early-withdrawal 10% additional tax to every pre-retirement distribution without checking the exception list, the age-59½ boundary, or the substantially equal periodic payment rules.
The penalty is the memorable part of the rule, so candidates stop there and never reach the exceptions for disability, medical expenses, qualified higher education, first-home purchase, or separation from service after age 55.
What to do instead
Maintain a numbered exception checklist and run every distribution scenario through it. Note which exceptions apply to IRAs only, which to employer plans only, and which to both.
Computing required minimum distributions from the prior year-end balance without confirming the correct valuation date, the correct life-expectancy or uniform table divisor, and the correct account owner age for the first distribution year.
The formula looks simple, so candidates plug in whatever balance and age appear first in the fact pattern.
What to do instead
For each RMD question, explicitly label the three inputs on scratch paper: balance date, age used, table used. If any input is not stated in the fact pattern, state the assumption you are making.
Mixing marginal and effective tax rates when evaluating a retirement withdrawal or Roth conversion strategy, and then recommending the action based on the wrong rate.
The bracket rate is the most visible number in the fact pattern, and candidates use it as if it applied to the whole conversion amount.
What to do instead
Always compute the tax on the last dollar added, not the average. Work the conversion in bracket-sized slices and compare the marginal cost of the conversion against the expected marginal rate on future withdrawals.
Ignoring the interaction between Social Security benefit taxation and other retirement income, so a withdrawal or conversion is evaluated as if it had no effect on the taxable portion of benefits.
The provisional-income formula has two thresholds and a phase-in, and candidates treat Social Security as either fully taxable or fully exempt.
What to do instead
Practise the provisional income computation as a standalone drill until the two-tier structure is memorised. Then, in any scenario involving both benefits and withdrawals, recompute provisional income after the proposed action.
Treating pension income, annuity payments, and lump-sum distributions as a single category and applying the same tax treatment to all three.
All three arrive as periodic payments from a retirement arrangement, so the distinct rules for qualified plans, nonqualified annuities, and the simplified method blur together.
What to do instead
Build a three-row comparison table covering basis recovery, taxation timing, and rollover eligibility for each income type. Test yourself by classifying ten short scenarios into the correct row.
Recommending a retirement income strategy without sequencing withdrawals across taxable, tax-deferred, and tax-free accounts, and without checking how the sequence changes the client's bracket in each year.
Candidates focus on the investment return of each account and treat the accounts as interchangeable pools of money rather than as different tax regimes.
What to do instead
For every strategy question, draw a simple three-column timeline showing which account is drawn in which year and what marginal rate applies. Compare at least two orderings before recommending one.
Skipping the eligibility and vesting checks before calculating a benefit, so the answer is arithmetically correct but the client is not yet entitled to the benefit at all.
Fact patterns supply salary and years of service that invite immediate calculation, and eligibility conditions sit in a sentence candidates skim past.
What to do instead
Before any benefit calculation, write a one-line eligibility statement citing the specific condition met or not met. If the condition is not met, answer the eligibility question first and stop.
