Inventory accessible cash and Roth contribution basis first, test whether a former-employer-plan exception fits, document every conversion clock, and use SEPP only if its rigid schedule is acceptable. These routes solve different access problems. None turns pretax money into tax-free spending.
This page is U.S.-focused educational information, not tax advice. Account type, plan terms, separation date, prior conversions, basis records, and later transactions can change the result. Confirm the current rule with the IRS, the plan administrator, and a qualified tax professional before moving money.
Start with an account-access inventory
List cash, taxable holdings and basis, each employer plan, each traditional arrangement, Roth regular contributions, Roth conversions by tax year, and Roth earnings. Add the current employer, separation date, and distribution choices allowed by each plan document. An account balance alone does not show which dollars are available on which terms.
The IRS says distributions from qualified retirement plans and individual retirement arrangements before age 59½ generally face an additional 10% tax unless an exception applies. The exception addresses that additional tax; it does not automatically erase regular income tax on a pretax distribution.
The FIRE Number and Timeline Planner identifies three planning buckets and enforces the access age entered for each. The planner identifies taxable, tax-deferred, and tax-free buckets, applies a user-chosen effective withdrawal rate to each, and enforces each entered access age. Those assumptions are sensitivity inputs, not tax-law calculations. It does not determine whether an entered age is legally available, apply early-distribution exceptions, track conversion clocks, calculate SEPP payments, or prepare a tax return. Keep the legal access schedule beside the planning result rather than treating the tool as an account-drawdown engine.
The Rule of 55 is tied to the employer plan
The IRS exception applies to a qualified plan distribution after separation from service when the separation occurs during or after the calendar year the employee reaches age 55. The IRS table says the same separation-from-service exception does not apply to an individual retirement arrangement.
The Rule of 55 is shorthand for an exception to the additional 10% tax, not a new account type and not a general promise of tax-free withdrawals. Pretax distributions can still be included in income. The separation year and the plan holding the money matter, which is why an automatic rollover can change the available route.
An exception in the tax law does not require a plan to offer the installment schedule a household wants. IRS guidance says a plan may permit money to remain after termination or may provide distribution choices under its terms. Read the summary plan description and ask the administrator what distributions the plan actually allows before relying on this route.
Roth conversion ladders need records and time
IRS ordering rules treat nonqualified Roth distributions as coming first from regular contributions, then from conversion and rollover contributions in first-in, first-out order, and then from earnings. Within a conversion layer, the taxable portion comes before the nontaxable portion. That ordering is the mechanical reason account history matters.
The taxable portion of a conversion is included in income in the conversion year. IRS guidance also applies a separate five-year period to each conversion when testing whether an early distribution of the taxable converted amount triggers the additional 10% tax. A “Roth conversion ladder” is planning shorthand for a series of documented conversions; it is not a separate IRS account.
Before counting ladder money, record the conversion tax year, taxable converted amount, current custodian records, and the first distribution year being considered. Also model where spending comes from while the conversion periods run. A ladder with no bridge assets is a list of future transfers, not a current spending plan.
SEPP under section 72(t) trades flexibility for access
The IRS describes three calculation methods for substantially equal periodic payments: a required-minimum-distribution method, a fixed-amortization method, and a fixed method using an account balance, mortality table, and interest rate. The exception can apply to a qualifying series from an individual retirement arrangement or qualified plan, subject to the rule's account and employment conditions.
Once the series starts, the IRS generally treats adding money to the account, taking an extra payment, or changing the payment method as a modification. The series must continue until the later of the fifth anniversary of the first payment or age 59½. An improper modification can produce the additional 10% tax for the modification year and recapture of the exception claimed in prior years, plus interest.
That rigidity is the real SEPP decision. Is the payment useful across good markets, bad markets, a move, a return to paid work, and an irregular expense? If the answer depends on changing the series later, choose another bridge or isolate only the balance deliberately committed to the calculation. Professional calculation and review are reasonable here because an execution error can reach back to earlier tax years.
Choose the route by constraint
Use the employer-plan exception only when the separation timing, plan, and permitted distribution form all fit. Use a conversion ladder only when there are bridge assets for the waiting period and clean Roth records. Use SEPP only when the scheduled series remains workable under adverse cases and the account can be kept free of unplanned transactions.
These routes can coexist, but stacking them adds recordkeeping and tax interactions. Draft the cash calendar first, then place each transaction into the annual withdrawal-order worksheet. The access route answers whether money can be reached without the additional tax. The withdrawal order answers whether reaching it that year makes sense.
The decision test
The drawdown plan is ready when every planned dollar has a source account, access rule, tax character, earliest usable date, required record, and fallback. If a plan is labeled only “Roth ladder” or “Rule of 55,” it is not yet mechanical enough to execute.
