Inherited IRA Calculator

Enter beneficiary age, decedent age, inherited account balance, and year of death. Select beneficiary type and account type carefully. The beneficiary categories may include an eligible designated beneficiary, a non-eligible designated beneficiary, a surviving spouse, or another category; their distribution timelines are not interchangeable.

A surviving spouse may have options that differ from those available to most nonspouse beneficiaries, including treating an inherited IRA as their own in some circumstances. The “spouse treat as own” input represents a special election in the calculator; it should not be selected unless the situation qualifies and the election is appropriate. A traditional IRA withdrawal estimate can help illustrate taxable withdrawals, but inherited-account rules still apply.

Expected return and inflation are projection assumptions. The entered tax rate is a simplified estimate of tax on distributions, not a tax-bracket calculation. The “age of majority” input may matter for certain minor beneficiaries; the applicable deadline can depend on legal status and the circumstances of the inheritance. Confirm the rule rather than assuming one age applies in every case.

For general RMD context, see required minimum distributions explained and the RMD calculator. An inherited Roth account has distinct tax treatment; compare an inherited Roth IRA RMD calculator.

Under the SECURE Act framework, many designated beneficiaries who are not eligible designated beneficiaries must empty an inherited account by the end of the 10th year after the original owner’s death. The exact rules depend on the date of death and beneficiary classification. For some beneficiaries, annual distributions may also be required in years 1 through 9, not just a full withdrawal in year 10.

Whether annual RMDs apply can depend on whether the original owner died before or after their required beginning date and on the beneficiary category. Regulations and transition relief have affected enforcement of certain annual distribution rules. Use the IRS’s current guidance rather than assuming that a 10-year deadline means “no withdrawals until year 10.” The IRS retirement plan and IRA required minimum distribution information provides official guidance.

The default non-eligible designated beneficiary selection is not enough to determine every schedule detail. The calculator also needs to interpret the account type, death year, ages, and applicable rules. Its result should be checked against a custodian’s beneficiary distribution options and tax professional’s interpretation where the facts are complex.

The standard RMD age of 73 (rising to 75 in 2033 under current SECURE 2.0 law) generally concerns an account owner’s lifetime RMD start, not a universal age threshold for every beneficiary. Do not apply the owner’s RMD age mechanically to an inherited account. A beneficiary’s distribution schedule follows separate rules.

A typical RMD calculation divides the applicable account balance by a life-expectancy divisor. The divisor and schedule depend on beneficiary rules; they cannot be specified from the supplied calculator data because its compute function was not available.

Annual required distribution = applicable account balance ÷ applicable IRS divisor

A projected account balance can be estimated by applying investment growth and subtracting the distribution. This is a simplified projection; actual returns and withdrawal timing can differ.

Projected balance after distribution = starting balance × (1 + expected return) − distribution

If a traditional inherited account distribution is taxable and the calculator applies a flat tax-rate assumption, the arithmetic structure is:

Estimated tax = taxable distribution × entered tax rate
After-tax distribution = taxable distribution − estimated tax

For example, if a distribution were $10,000 and the entered tax assumption were 24%, the arithmetic would be $10,000 × 0.24 = $2,400 estimated tax and $7,600 after tax. This is an illustration of the formula, not a result for the default account. Actual tax depends on the beneficiary’s total taxable income, filing status, deductions, state law, and whether the account is traditional or Roth.

The table summarizes how changing beneficiary status can change the distribution framework. It does not assign invented distribution amounts; the applicable schedule depends on the specific facts and current rules.

A beneficiary classification mistake can change both withdrawal timing and tax concentration. A spouse and an adult child may inherit the same balance but face different distribution choices. Compare a nonspouse inherited IRA RMD estimate and a separate inherited IRA tax estimate.

Traditional inherited IRA distributions are generally included in taxable income, while qualified Roth IRA distributions are generally tax-free. However, Roth accounts can still have distribution deadlines, and “tax-free” does not mean “no distribution rules.” Check the account’s Roth status, original owner’s history, and beneficiary rules.

A large withdrawal in one year may increase taxable income and affect other income-sensitive costs or benefits. Spreading withdrawals over several years can reduce tax spikes in some situations, but it must fit the required deadline and any annual RMDs. The tradeoff is between tax-bracket management, continued tax-deferred growth, and avoiding a large final-year distribution.

A missed RMD can trigger an excise tax. Under current federal law, the shortfall excise tax is generally 25% of the amount not distributed, reduced to 10% if corrected within the correction window and applicable requirements are met. The IRS may waive the tax in qualifying cases when reasonable steps are taken to correct the shortfall. This penalty is distinct from income tax due on distributions. Check current IRS rules and correction procedures before relying on a general estimate.

Does the 10-year rule mean I can wait ten years to withdraw everything?

Not always. Some beneficiaries may have annual RMDs during the 10-year period, depending on the original owner’s RMD status and beneficiary category. Verify the schedule with the IRA custodian and current IRS guidance.

Is every beneficiary subject to the same 10-year deadline?

No. Spouses, eligible designated beneficiaries, certain minor children, and other beneficiary types may follow different rules. The beneficiary’s relationship and status at the owner’s death matter.

Are inherited traditional IRA withdrawals taxable?

Usually, distributions from a traditional inherited IRA are taxable as ordinary income, subject to account basis and applicable exceptions. A qualified Roth distribution is generally tax-free, but distribution deadlines may still apply.

Should I take distributions evenly or wait until the final year?

It depends on the required schedule, expected tax bracket, investment assumptions, and other income. Even withdrawals can help avoid concentrating taxable income in one year, while delaying may preserve more tax-deferred growth—but waiting can create a large final-year tax bill.

Can a spouse treat an inherited IRA as their own?

A surviving spouse may be able to elect to treat the account as their own, but the right choice depends on age, cash needs, RMD timing, and beneficiary plans. Compare the available options before making an election, because it can change withdrawal rules.

What happens if I miss an inherited IRA RMD?

A missed amount can lead to an excise tax, generally 25% of the shortfall, potentially reduced to 10% if corrected within the permitted period. Correct the shortfall promptly and consult IRS guidance about waiver eligibility.

Ask the custodian for the account’s date-of-death value, beneficiary designation, original owner’s RMD status, and written distribution deadline. Confirm whether annual RMDs apply, then model several withdrawal schedules using the correct beneficiary type and account type. Compare the tax consequences with an inherited IRA tax calculator and the RMD tax calculator. Do not take a distribution solely because a calculator projects one; verify the governing rule and deadline first.
