What Are Substantially Equal Periodic Payments (72(t))?

Research. Education. Perspective.

Substantially equal periodic payments, often shortened to SEPPs or informally called 72(t) payments, are a federal tax mechanism that can allow certain retirement-account distributions before age 59½ without the usual 10% additional tax on early distributions.^[1][2]

The concept sounds simple:

Take a calculated series of payments from a retirement account and receive an exception from the 10% additional tax.

The implementation is not simple.

Once a SEPP is established, the taxpayer generally commits to a tightly controlled payment pattern and account structure for a minimum period.

A mistake can be expensive because an improper modification can trigger:

• the 10% additional tax for the year of the modification
• recapture of the 10% additional tax that would have applied to earlier SEPP distributions
• interest on the deferred recapture amount^[1][4]

SEPPs are therefore best understood as a rule-bound distribution system, not as a flexible early-retirement withdrawal account.

Key Takeaways

- A SEPP is a series of retirement-account distributions, not a separate account type.^[1][2] - A valid SEPP can provide an exception to the 10% additional tax on taxable distributions before age 59½.^[1] - The exception does not automatically eliminate ordinary income tax on pre-tax distributions. - Employer-plan participants generally must separate from service with the employer maintaining the plan before the SEPP begins.^[1] - IRAs do not have the same separation-from-service requirement for this exception.^[1] - Notice 2022-6 recognizes three standard calculation methods: RMD, fixed amortization and fixed annuitization.^[1][2] - The RMD method generally recalculates the payment annually. - Fixed amortization and fixed annuitization generally establish a level annual payment at the beginning of the series.^[2][4] - Fixed-method interest cannot exceed the greater of 5% or 120% of the federal mid-term rate for either of the two months before the first payment month.^[1][2] - A SEPP generally cannot be modified before the later of: 1. the fifth anniversary of the first SEPP payment, or 2. the date the taxpayer reaches age 59½.^[1] - An improper modification can create recapture tax plus interest.^[1][4] - IRS guidance permits a one-time change from either fixed method to the RMD method without treating the switch as a prohibited modification.^[1][2][4]

What Does “72(t)” Mean?

The informal name comes from Internal Revenue Code Section 72(t).

Section 72(t) generally imposes an additional 10% tax on taxable early distributions from specified retirement arrangements.

The same section contains exceptions.

One exception covers distributions that are part of a series of substantially equal periodic payments made over:

• the taxpayer's life expectancy, or
• the joint life expectancies of the taxpayer and a designated beneficiary.^[1]

> ROIStreet Definition > > A substantially equal periodic payment arrangement is a retirement-account distribution series calculated under accepted federal methods that can qualify for an exception from the 10% additional tax on early distributions when the statutory and IRS requirements are maintained.

The phrase substantially equal refers to the prescribed calculation method.

It does not mean the taxpayer can simply choose a number that feels approximately consistent from year to year.

What Tax Does a SEPP Avoid?

Federal retirement distributions can involve two different taxes.

Ordinary income tax

A traditional IRA or pre-tax employer-plan distribution is generally taxable to the extent the distributed amount has not previously been taxed.

10% additional tax

A separate additional tax generally applies to taxable early distributions before age 59½ unless an exception applies.^[1][3][4]

A valid SEPP can provide one such exception.

Example

Assume a taxpayer receives a fully taxable:

$30,000

SEPP distribution before age 59½.

If the series satisfies the federal requirements:

• the $30,000 can still be included in ordinary taxable income
• the separate $3,000 additional tax that would equal 10% of the distribution may not apply under the SEPP exception

The exact income-tax liability depends on the taxpayer's broader tax situation.

Penalty exception does not mean tax-free distribution.

Which Accounts Can Use a SEPP?

IRS guidance identifies retirement arrangements subject to Section 72(t), including certain:

• qualified plans under Section 401(a)
• 403(a) annuity plans
• 403(b) annuity contracts
• traditional IRAs
• individual retirement annuities^[1]

But employer plans and IRAs have an important difference.

Employer Plans Require Separation From Service

If the payments come from an employer arrangement such as a qualifying:

• 401(k)
• pension plan
• 403(a)
• 403(b)

the taxpayer generally must be separated from service with the employer maintaining the plan before SEPP payments begin for this exception to apply.^[1]

That condition does not apply to an IRA.

Example

A 50-year-old employee still working for Employer A wants to begin SEPP withdrawals from Employer A's 401(k).

The SEPP exception generally is not available from that employer plan while the worker remains employed by the employer maintaining it.

If the worker later separates and the plan permits distributions, the analysis can change.

IRA SEPPs Do Not Require Job Separation

An IRA is individually owned.

The taxpayer does not need to terminate employment merely to establish a SEPP from an IRA.^[1]

A person can therefore potentially:

• remain employed
• own a traditional IRA
• establish a qualifying SEPP from that IRA

provided the other requirements are satisfied.

This is one reason SEPPs and the Rule of 55 are fundamentally different.

SEPP vs. Rule of 55

The Rule of 55 is often simpler when available because it does not require a prescribed multi-year payment series.

SEPPs can reach younger taxpayers and can apply to IRAs.

That flexibility comes with greater rigidity after the series begins.

The Three IRS Calculation Methods

Notice 2022-6 provides three standard methods for determining SEPP amounts:^[1][2]

1. Required minimum distribution method
2. Fixed amortization method
3. Fixed annuitization method

The methods are not interchangeable.

They can produce different annual payment amounts from the same account.

1. Required Minimum Distribution Method

Under the RMD method, the annual payment is generally determined using:

• the account balance
• an applicable life expectancy or distribution-period table
• the taxpayer's age for the distribution year
• the beneficiary's age where the permitted joint table is used^[1][2]

The critical feature is:

the payment is generally recalculated each year.^[4]

That means the payment can rise or fall as:

• account value changes
• age changes
• the applicable distribution period changes

Conceptual formula

Annual SEPP = account balance ÷ applicable life-expectancy factor

This resembles required minimum distribution mathematics.

It does not mean the taxpayer is old enough to be subject to ordinary RMD rules.

The RMD method is simply the name of the SEPP calculation method.

RMD Method Is Variable

Suppose the account declines significantly during the year.

The next year's recalculated payment can decline because the new account balance enters the calculation.

If the account grows, the calculated amount can potentially increase.

This flexibility distinguishes the RMD method from the two fixed methods.

2. Fixed Amortization Method

The fixed amortization method calculates an annual payment that amortizes the account balance over an applicable life-expectancy period using a permitted interest rate.^[2]

Once established:

the annual payment generally remains the same in each succeeding distribution year.^[2][4]

Conceptually, the calculation uses:

• starting account balance
• life expectancy
• permitted interest rate

to solve for a level annual payment.

This resembles a financial amortization calculation.

3. Fixed Annuitization Method

The fixed annuitization method determines the annual payment by dividing the account balance by an annuity factor based on:

• mortality assumptions
• taxpayer age
• possibly joint lives with a beneficiary
• a permitted interest rate^[2]

Again:

the resulting annual payment generally remains level in succeeding years.^[2][4]

This method is mathematically different from fixed amortization even though both normally create fixed annual payments.

Three Methods at a Glance

The method with the highest initial payment is not automatically the most appropriate.

The tax framework does not remove:

• longevity risk
• sequence-of-returns risk
• portfolio risk
• inflation risk
• tax-bracket effects

What Interest Rate Can Be Used?

For fixed amortization and fixed annuitization, Notice 2022-6 limits the selected interest rate.

The rate cannot exceed the greater of:

1. 5%, or
2. 120% of the federal mid-term rate

for either of the two months immediately preceding the month in which the first SEPP payment is made.^[1][2]

Example structure

Assume a first payment is scheduled for September.

The relevant federal mid-term rate comparison looks to:

• July
• August

The taxpayer can use a permitted rate up to the applicable maximum under Notice 2022-6.

The exact monthly federal rates should be checked when the series begins.

Why the Interest Rate Matters

For the fixed methods, a higher permitted interest assumption will generally support a higher calculated annual payment than a lower interest assumption, all else equal.

But the calculation is not a return guarantee.

If the portfolio actually earns less than the assumed rate, the account can deplete faster than the mathematical schedule implies.

The IRS interest-rate rule determines the permitted calculation input.

It does not forecast market returns.

Which Life Expectancy Tables Can Be Used?

Notice 2022-6 provides specified table choices.

For the RMD and fixed amortization methods, permitted tables can include:

• Uniform Lifetime Table
• Single Life Table
• Joint and Last Survivor Table^[1][2]

The Joint and Last Survivor Table can be used subject to beneficiary-identification requirements.

For fixed annuitization, the calculation uses the mortality rates specified under the applicable regulations and Notice 2022-6.

The table choice can materially affect the annual payment.

This is one reason SEPP calculations should be documented carefully.

How Is the Account Balance Determined?

The account balance is a core input.

For fixed amortization and fixed annuitization, Notice 2022-6 requires a balance determined in a reasonable manner based on the facts and circumstances.^[2]

The guidance provides a framework for acceptable valuation timing around the beginning of the series.

For readers, the practical lesson is simpler:

Do not casually choose an old statement balance merely because it produces a preferred payment.

The balance date should comply with the applicable IRS guidance.

A Conceptual $500,000 Example

Assume an IRA owner establishes a SEPP using a:

$500,000

account balance.

The annual payment will depend on:

• age
• beneficiary assumptions if applicable
• method chosen
• life expectancy table
• permitted interest rate for a fixed method
• account value in later years under the RMD method

The three methods can therefore produce different answers.

ROIStreet does not present one illustrative dollar amount as a universal SEPP result because the correct figure depends on the exact inputs and method.

That distinction is important.

A SEPP calculation should be reproducible from documented inputs.

How Long Must a SEPP Continue?

This is the most important duration rule.

The series generally must continue until the later of:

1. the fifth anniversary of the first SEPP payment, or
2. the date the taxpayer reaches age 59½.^[1]

Many explanations shorten this to:

"five years or age 59½."

That wording is dangerous because it can sound like the earlier date ends the commitment.

It is the later date.

Example: SEPP Begins at Age 50

Suppose the first payment is made when the taxpayer is 50.

Five years later, the taxpayer is only 55.

The five-year milestone has passed.

But age 59½ has not.

The series generally must continue until the taxpayer reaches age 59½.

The required period is therefore roughly 9½ years, not five.

Example: SEPP Begins at Age 58

Suppose the first payment occurs at age 58.

The taxpayer reaches age 59½ only about 18 months later.

But the fifth anniversary has not arrived.

The series generally must continue through the required five-year period.

This is the opposite side of the later-of-two-dates rule.

A Better Duration Table

Exact dates—not just ages—matter.

What Counts as a Modification?

Once a SEPP is established, IRS guidance imposes strict limitations.

The taxpayer generally cannot:

• add money to the SEPP account
• take distributions from the account other than the required SEPP payments
• establish more than one SEPP for the same account for the same year
• change the annual amount outside permitted rules^[1]

Normal changes in account value caused by investment performance are not prohibited modifications.

Market movement is expected.

The problem is taxpayer-directed account or payment activity that changes the prescribed series.

Extra Withdrawals Are Dangerous

Assume a taxpayer's valid annual SEPP amount is:

$24,000

The taxpayer later takes:

• required SEPP: $24,000
• emergency extra withdrawal: $15,000

The total annual distribution becomes:

$39,000

Absent a separate permitted exception within the SEPP modification rules, the extra payment can cause the SEPP to be treated as modified.^[1]

This can expose the taxpayer to recapture tax.

The fact that the extra money was genuinely needed does not automatically protect the SEPP structure.

Contributions Can Be a Problem Too

Suppose an IRA has been designated as the account supporting the SEPP.

The taxpayer later contributes new money to that same IRA.

IRS guidance generally prohibits additions to the account once the SEPP is established.^[1]

That can create a modification issue.

A SEPP account should therefore be treated operationally as a controlled account, not an ordinary IRA that can be freely funded and tapped.

Can a SEPP Account Be Split?

Account restructuring during a SEPP can be complex.

IRS guidance addresses circumstances involving transfers and rollovers, but the transaction must preserve the required payment structure.

The safe principle is:

Do not assume moving, splitting, merging or partially transferring a SEPP account is tax-neutral merely because the transfer itself would normally qualify as an IRA transfer or rollover.

The SEPP rules sit on top of ordinary retirement-account transfer rules.

Can Payments Be Monthly?

Yes.

IRS guidance allows the taxpayer to split the annual required amount into installments during the year.^[1]

For example, if the annual SEPP amount is:

$24,000

the taxpayer could potentially receive:

• one annual $24,000 payment
• two $12,000 semiannual payments
• four $6,000 quarterly payments
• twelve $2,000 monthly payments

provided the annual total and timing comply with the established SEPP.

The important number is the required annual amount.

Payment frequency does not change the annual calculation.

Separate SEPP Accounts Cannot Be Aggregated

A taxpayer can potentially establish SEPPs from more than one retirement account.

But each account has its own series.

IRS guidance states that annual amounts from separate SEPP accounts cannot simply be aggregated and withdrawn from one account.^[1]

Example

IRA A annual SEPP:

$18,000

IRA B annual SEPP:

$12,000

The taxpayer cannot ordinarily take the entire:

$30,000

from IRA A and zero from IRA B while claiming both series were satisfied.

Each SEPP must be maintained with the account from which it was established.

The One-Time Switch to the RMD Method

Notice 2022-6 permits an important exception to the general no-change rule.

A taxpayer who began using:

• fixed amortization, or
• fixed annuitization

may generally make a one-time switch to the RMD method for a later distribution year.^[1][2][4]

That change is not treated as a prohibited modification for recapture-tax purposes.

After the switch:

• the RMD method applies for the year of the switch
• the RMD method generally continues for subsequent years^[1]

The taxpayer cannot freely switch back and forth.

Why the Fixed-to-RMD Switch Matters

The RMD method often produces a lower payment than a fixed method because the payment is recalculated using current account value and life expectancy.

That can be useful if:

• the portfolio declined
• the fixed annual payment became burdensome
• the taxpayer's cash-flow need decreased

But the permitted switch is a tax-rule mechanism, not a recommendation.

Changing methods changes the withdrawal path and potentially the account's longevity.

What Happens If the SEPP Is Modified Too Early?

An improper modification before the required ending date can produce a severe tax result.

IRS guidance describes two components in the year of modification.^[1]

1. Current-year additional tax

The taxpayer can owe the 10% additional tax on taxable distributions in the year the series is broken.

2. Recapture tax

The taxpayer can also owe the additional tax that would have applied to prior SEPP distributions if the exception had never applied.

Interest is added for the deferral period.^[1][4]

This is why SEPP errors can become retroactively expensive.

Recapture Example

Assume a taxpayer receives valid SEPP distributions of:

• Year 1: $30,000
• Year 2: $30,000
• Year 3: $30,000

Assume all amounts were taxable and otherwise would have been subject to the 10% additional tax.

The taxpayer then improperly modifies the series in Year 4.

The prior avoided additional tax would conceptually have been:

$90,000 × 10% = $9,000

The recapture framework can bring that prior tax back into the Year 4 calculation, plus interest, while the Year 4 distribution can also face the current additional tax.^[1]

This example is simplified and does not calculate interest.

What If the Account Runs Out of Money?

Investment losses and withdrawals can deplete an account.

IRS guidance provides relief where the assets in an individual account plan or IRA are completely depleted and the final annual distribution is less than the normal SEPP amount solely because the account reaches zero.^[1]

In that circumstance, the short final distribution does not itself trigger recapture.

This prevents the rule from demanding money that no longer exists.

But intentional extra withdrawals that caused the depletion are a different issue.

Death or Disability

The federal SEPP modification rules provide exceptions when the change occurs because of:

• death
• disability

and certain distributions involving qualified public safety employees.^[1]

These exceptions recognize circumstances in which continuing the original series may no longer be appropriate.

The exact statutory facts still matter.

SEPPs and Roth IRAs

Roth IRA taxation adds another layer.

A Roth IRA distribution can contain:

• regular contributions
• conversion amounts
• earnings

with ordering and additional-tax rules that differ from traditional IRA taxation.

A SEPP can potentially affect the 10% additional-tax analysis without automatically converting otherwise taxable Roth earnings into tax-free income.

The useful principle is:

SEPP status and Roth distribution qualification are separate tax questions.

SEPPs and Roth Conversions

IRS Publication 590-A explains that a taxpayer already taking substantially equal periodic payments from a traditional IRA can convert amounts to a Roth IRA and continue the periodic-payment structure under applicable rules.^[3]

This is technical planning territory.

The transaction can involve:

• conversion income
• SEPP continuation
• Roth ordering rules
• account tracking

A conversion should not be assumed to reset or erase the existing SEPP commitment.

SEPPs and RMD Age

A SEPP can begin decades before ordinary required minimum distributions apply.

The phrase RMD method can therefore be confusing.

A 50-year-old using the RMD method for a SEPP is not taking a legally required age-based RMD.

The taxpayer is using the RMD calculation method to determine the SEPP amount.

Ordinary RMD requirements later arise under a different section of federal retirement law.

SEPP vs. Ordinary Retirement Withdrawals

A SEPP provides early access by accepting restrictions that are generally unnecessary after age 59½.

When Might Someone Consider a SEPP?

Common situations can include a person who:

• retires well before age 59½
• leaves an employer before qualifying for the Rule of 55
• has substantial IRA assets
• needs a predictable annual distribution
• cannot use another early-distribution exception for the full cash-flow need

But a SEPP should not be selected merely because it avoids the 10% additional tax.

The broader financial questions remain.

The Cash-Flow Lock-In Problem

A fixed SEPP method creates a recurring withdrawal obligation.

That can become problematic if:

• spending needs fall
• investment values decline
• inflation changes
• tax rates change
• other income begins
• the taxpayer returns to work
• a large emergency expense arises

The series is intentionally rigid.

That rigidity is part of the tradeoff for the tax exception.

Sequence-of-Returns Risk

Consider an early retiree withdrawing a fixed SEPP amount during a severe market decline.

The account can face two pressures:

1. lower market value
2. continued required withdrawals

Selling assets after a decline can permanently reduce the capital available to participate in a later recovery.

The SEPP tax rule does not protect against this investment risk.

Inflation Risk

A fixed annual SEPP can lose purchasing power over time if inflation is positive.

For example, a fixed:

$30,000

annual distribution does not automatically rise with the cost of living.

The RMD method can vary annually, but it is not an inflation index.

Its changes are driven by:

• account balance
• life expectancy factor

not directly by CPI or another inflation measure.

Tax-Bracket Risk

SEPP distributions can increase taxable income.

That can interact with:

• federal income-tax brackets
• state taxes
• capital gains
• Affordable Care Act premium-tax-credit calculations where relevant
• taxation of other retirement income later
• Medicare income-related premiums once applicable

The 10% additional-tax exception should not be analyzed in isolation from the ordinary tax consequences.

The Account Segmentation Concept

One practical feature of SEPP planning is that the series can be established using one retirement account rather than every retirement dollar a person owns.

Conceptually, an IRA owner with multiple IRAs can have:

• IRA A designated for a SEPP
• IRA B left outside the SEPP

The non-SEPP account remains subject to its normal rules.

However, the SEPP account itself must be maintained under the SEPP restrictions.

Transfers designed to create the account structure should be completed and documented carefully before payments begin.

Why Account Size Matters

A larger starting account generally supports a larger calculated payment.

But placing too much retirement capital into a SEPP account can reduce flexibility because that larger pool becomes subject to the series restrictions.

Placing too little into the SEPP account can produce inadequate cash flow or faster depletion.

The account-size decision therefore links:

• tax rules
• portfolio design
• spending needs
• flexibility

This is more than an arithmetic exercise.

A SEPP Setup Checklist

1. Identify the account type

Determine whether the assets are in an:

• IRA
• 401(k)
• 403(b)
• pension
• other qualified plan

2. Confirm separation from service if using an employer plan

Do not assume an active employee can establish a SEPP from the current employer plan.

3. Determine the account balance

Use a valuation method consistent with Notice 2022-6.

4. Select the life expectancy framework

Document the table and beneficiary assumptions.

5. Select the calculation method

Choose among:

• RMD
• fixed amortization
• fixed annuitization

6. For a fixed method, document the interest rate

Verify the maximum permitted rate for the month the series begins.

7. Calculate the annual payment

Retain the calculation workpapers.

8. Establish payment frequency

Annual, quarterly or monthly installments can be possible as long as the correct annual amount is distributed.

9. Calculate the minimum ending date

Determine both:

• fifth anniversary of first payment
• age-59½ date

Use the later.

10. Protect the SEPP account

Avoid:

• extra withdrawals
• new contributions
• casual transfers
• account consolidation
• unauthorized method changes

11. Review Form 1099-R and Form 5329

Confirm tax reporting reflects the applicable exception.

12. Recalculate annually if using the RMD method

Do not simply repeat last year's amount.

Common SEPP Mistakes

Choosing a payment before choosing a method

The IRS method determines the payment—not the other way around.

Treating five years as the maximum commitment

For younger taxpayers, the commitment can last much longer.

Treating age 59½ as the only endpoint

A series begun near age 59½ may have to continue well beyond that age because the fifth anniversary occurs later.

Taking an emergency extra withdrawal

The extra distribution can jeopardize the entire series.

Adding a new IRA contribution

A contribution to the SEPP account can create a modification issue.

Forgetting annual recalculation under the RMD method

The RMD method is variable by design.

Recalculating a fixed method each year

Fixed amortization and fixed annuitization generally establish level payments.

Changing fixed methods because rates changed

A later interest-rate environment does not provide a general license to redo the original fixed calculation.

Ignoring the one-time RMD switch

A fixed-method taxpayer can have one permitted path to the RMD method.

Using one account to satisfy payments for another SEPP account

Separate SEPPs must be maintained separately.

Frequently Asked Questions

What is a 72(t) distribution?

The term commonly refers to a distribution made as part of a series of substantially equal periodic payments qualifying for an exception to the 10% additional tax under Section 72(t).^[1]

Are 72(t) withdrawals tax-free?

No. A valid SEPP can avoid the 10% additional tax, but ordinary income tax can still apply to taxable retirement distributions.^[1][3][4]

Can I use a SEPP from an IRA?

Yes. IRAs can qualify for the substantially equal periodic payment exception, and the employer-separation requirement does not apply to an IRA.^[1]

Can I use a SEPP from my current employer's 401(k)?

Generally, the SEPP exception for a qualified employer plan requires separation from service with the employer maintaining the plan before payments begin.^[1]

What are the three SEPP calculation methods?

The IRS recognizes the required minimum distribution method, fixed amortization method and fixed annuitization method under Notice 2022-6.^[1][2]

Which SEPP method gives the highest payment?

There is no universal answer. The result depends on age, account balance, life expectancy assumptions, beneficiary assumptions and permitted interest rates.

What interest rate can I use?

For fixed amortization and fixed annuitization, the rate cannot exceed the greater of 5% or 120% of the federal mid-term rate for either of the two months immediately before the first payment month.^[1][2]

How long do 72(t) payments have to continue?

Generally until the later of the fifth anniversary of the first payment or the date the taxpayer reaches age 59½.^[1]

Can I take monthly SEPP payments?

Yes. The annual amount can generally be divided into installments, provided the proper annual total is distributed in the correct annual period.^[1]

Can I take extra money from the SEPP account?

Doing so can modify the series and potentially trigger current additional tax and recapture tax.^[1]

Can I switch SEPP methods?

A taxpayer using fixed amortization or fixed annuitization may generally make a one-time switch to the RMD method without triggering recapture.^[1][2][4]

What happens if I break a SEPP?

An improper modification can result in the 10% additional tax for the modification year plus recapture of the additional tax that would have applied to prior SEPP distributions, with interest.^[1][4]

What happens if the SEPP account reaches zero?

IRS guidance provides that complete depletion of an individual account or IRA can allow a final distribution below the normal annual amount without itself causing recapture, assuming the depletion occurs under the applicable rules.^[1]

The Bottom Line

Substantially equal periodic payments can provide access to retirement assets before age 59½ without the usual 10% additional tax.

But the exception comes with a significant constraint:

the taxpayer gives up flexibility in exchange for the tax exception.

A valid SEPP requires attention to:

• account type
• employment status for employer plans
• account balance
• life expectancy assumptions
• calculation method
• permitted interest rate
• annual payment amount
• payment frequency
• minimum duration
• account activity
• tax reporting

The three methods behave differently.

The RMD method generally recalculates annually.

The fixed amortization and fixed annuitization methods generally establish level payments.

A one-time switch from a fixed method to the RMD method is generally permitted.

The most consequential rule is the duration requirement:

the series normally must remain unmodified until the later of the fifth anniversary of the first payment or age 59½.

Breaking the series early can cause prior tax benefits to be recaptured with interest.

The useful question is therefore not simply:

"How much can I withdraw under 72(t)?"

It is:

"What annual payment can be supported under an accepted IRS method, for how many years must I maintain it, and can I realistically keep this account untouched except for the prescribed distributions throughout that period?"

That is the decision a SEPP actually requires.
