When an annuity owner dies before recovering all of their after-tax investment through payments, the leftover cost basis can be claimed as an unrecovered investment in annuity deduction on the decedent’s final income tax return. The authority is Internal Revenue Code Section 72(b)(3), and the deduction goes on Line 16 of Schedule A under “Other Itemized Deductions.” It is not a miscellaneous itemized deduction, so the Tax Cuts and Jobs Act suspension does not touch it, and there is no 2% adjusted-gross-income floor.
When the Deduction Is Available
Three conditions all have to be met. The annuity must have already passed its annuity starting date and been paying out. Payments must have ended because the annuitant died. And some portion of the original after-tax investment must remain unrecovered at death.
The clean case is a straight-life annuity that pays only for the annuitant’s lifetime. If the annuitant dies earlier than the life expectancy used to build the exclusion ratio, some of the investment was never returned, and the estate can claim what is left.
Contracts With Survivor or Refund Features
Many annuities keep paying after the primary annuitant dies. Joint-and-survivor annuities, period-certain guarantees, and refund features all continue the recovery of basis in the hands of someone else. When a beneficiary continues to receive payments, the cost basis moves with the contract rather than becoming a deduction on the decedent’s return.
For a joint-and-survivor annuity, IRS Publication 939 confirms that the surviving spouse keeps using the same exclusion ratio the original annuitant used, receiving partially tax-free payments until the net cost is fully recovered. The Section 72(b)(3) deduction only becomes available on the return of the last surviving annuitant, and only if basis is still unrecovered when they die. Executors should read the contract closely: if any party remains entitled to future payments, the deduction is not available.
Death Before Payments Began
If the owner dies while the contract is still in the accumulation phase and payments never started, Section 72(b)(3) does not apply. There is no annuity starting date and no exclusion ratio. Instead, the death benefit paid to the beneficiary is taxable only to the extent it exceeds the decedent’s cost basis. The beneficiary reports the excess as income in respect of a decedent, and the basis offsets the death benefit directly.
Qualified Plans and After-Tax Contributions
The deduction really lives with non-qualified annuities bought with after-tax dollars, because every premium creates basis. Qualified annuities funded through a 401(k), 403(b), or traditional IRA generally have no basis at all, since contributions were pre-tax. Publication 575 states that amounts withheld from pay on a tax-deferred basis are not treated as part of the cost of the annuity payment. A plan funded entirely with pre-tax money has zero cost basis, and there is nothing to deduct at death.
The exception is a qualified plan that received after-tax employee contributions. Older pension plans sometimes have these, and so do plans where an employee contributed above the pre-tax limit. Any after-tax contributions that were not recovered through the exclusion ratio qualify for the same deduction.
Calculating the Unrecovered Amount
Start with the total after-tax dollars paid into the contract. Subtract every dollar that came back tax-free through the exclusion ratio over the years the annuity was paying. What remains is the deduction.
If the decedent put $100,000 into a non-qualified annuity and received $60,000 in tax-free principal through the exclusion ratio before dying, the unrecovered investment is $40,000, and that $40,000 goes on the final return.
A few adjustments can complicate the arithmetic. For non-qualified annuities, partial withdrawals taken before the annuity starting date come out of earnings first and do not reduce cost basis until all earnings have been pulled out. Once payments began, the exclusion ratio governs how much of each payment reduced basis. Loans from qualified retirement plans that failed the repayment rules may have been treated as taxable distributions, which can reduce the remaining investment in the contract. Any withdrawals or loans during the life of the contract have to be traced through to arrive at an accurate basis at death.
Reporting It on the Final Return
The deduction is claimed on Schedule A of the decedent’s final Form 1040, covering income from January 1 through the date of death. On Line 16, “Other Itemized Deductions,” the executor enters the dollar amount and writes “Unrecovered investment in annuity” next to it. That label matters because it distinguishes the entry from the suspended miscellaneous deductions the IRS no longer allows.
Itemizing only helps if total itemized deductions exceed the standard deduction. For 2026, the standard deduction is $16,100 for single filers and $32,200 for joint filers. A sizable unrecovered investment usually pushes total itemized deductions well past those figures, especially combined with state taxes, mortgage interest, or medical costs from the final illness. For smaller amounts, run the numbers both ways before itemizing.
The final return follows the normal individual deadline: April 15 of the year after death. A death in 2026 means a return due April 15, 2027, absent an extension. The executor or personal representative signs on behalf of the decedent.
Documentation to Gather
The IRS will not take the deduction on faith. Build a file that contains the original annuity contract showing total premiums paid, every Form 1099-R issued over the life of the contract (Box 2a shows the taxable portion of each year’s distributions and Box 5 shows the non-taxable portion), prior-year tax returns showing exclusion amounts already claimed, and a final letter from the insurance company confirming that the contract has terminated with no further payments owed to any party. Records of any partial withdrawals or loans are needed to trace basis adjustments.
Getting the insurer’s final statement can take weeks. Request it promptly, because the filing deadline will not wait. A final Form 1099-R for the year of death will typically show the remaining investment in the contract, which serves as a useful cross-check against the executor’s own math.
Why the Full Amount Is Deductible
The TCJA suspended most miscellaneous itemized deductions, and the One Big Beautiful Bill Act made that suspension permanent for tax years beginning after 2017. The unrecovered annuity deduction was never a miscellaneous itemized deduction, though. Section 67(b) defines miscellaneous itemized deductions as everything except items on a specific list of twelve, and the Section 72(b)(3) deduction sits at number ten on that list. The suspension does not reach it, and neither did the old 2% adjusted-gross-income floor. The full unrecovered amount is deductible.
Section 72(b)(3)(C) adds a feature many executors miss: the deduction is treated as attributable to a trade or business for purposes of the net operating loss rules. Normally, nonbusiness itemized deductions can only offset nonbusiness income when testing for an NOL. Publication 536 confirms the unrecovered annuity deduction is classified as a business deduction for this purpose, so it can fully offset all types of income on the final return, not just nonbusiness income. If the decedent had $20,000 of income in the final year and $50,000 of unrecovered investment, the entire deduction applies against all of that income.
In practice, any NOL that results from a final return has nowhere to go. Current law only permits carryforwards, and a deceased taxpayer has no future tax years. The excess deduction cannot pass to beneficiaries and cannot be carried back. It still zeroes out the final return’s tax; it just cannot do more than that.
