Updated September 28, 2026. Quick answer: code C is not the ordinary tax-free life insurance death benefit most beneficiaries receive. It reports a death benefit paid under a policy that changed hands in a reportable policy sale before the insured’s death, and part of that payment is taxable. Section 6050Y is the reporting rule; section 101(a)(2) is what limits the tax-free exclusion after a transfer for valuable consideration.
Read box by box from the IRS form text: Form 1099-R boxes 12 and 13.
What the IRS tells the payer
From the current instructions, code C is “Reportable death benefits under section 6050Y”. The full instruction text reads: “Use code C for a distribution to report payments of reportable death benefits.” It may be used with: D.
Why this one is taxable at all
Ordinary life insurance proceeds paid to the original policy’s beneficiary are generally not taxable income. Code C exists because the rules change once a policy has been sold: section 6050Y requires reporting on the buyer’s eventual payout, and Form 1099-R’s recipient instructions confirm the treatment directly: “If code C is shown in box 7a, the amount shown in box 1 is a receipt of reportable death benefits that is taxable in part.”
Which line it drives
Box 13 of the form separately shows the date of payment for reportable death benefits. The payer estimates the buyer’s investment in the contract and enters it in box 5. The 2026 Instructions for Forms 1099-R and 5498 and the 2025 Instructions for Form 1040 do not name a return line for this payment, so ask a preparer where the taxable part goes.
The 10% additional tax
Section 72(t) imposes the 10% additional tax on amounts received from a qualified retirement plan, and code C reports a payment under a life insurance contract, so the Form 5329 death exception is not the test that applies to it. The instructions for code C say nothing about an additional tax.
Common mistakes
- Assuming a code C payment is entirely tax-free the way an ordinary death benefit is. Only the basis portion is excluded.
- Confusing code C with the annuity and life insurance income covered by code D, the code it may be used with.
Box 7 is the payer’s claim, not the law
The code in Box 7a records what the custodian knew when it cut the cheque. It is not a ruling on what you owe, and the IRS instructions say so in as many words. On code 1 the instruction to payers is to use it “even if the distribution is made for medical expenses, health insurance premiums, qualified higher education expenses, a first-time home purchase…” and a list of other genuine statutory exceptions.
