Short answer
A QLAC is a DIA inside a traditional IRA, with IRS perks a plain DIA does not have.
A deferred income annuity (DIA) and a QLAC both pay income starting at a future date. The difference is the money and the rules. A QLAC is a DIA bought inside a traditional IRA, so the IRS adds perks: up to a $210,000 premium (for 2025 and 2026) is excluded from the balance used to figure your RMDs, and income must begin no later than age 85. A plain DIA usually uses non-IRA money and has no RMD interaction. Choose a QLAC for IRA money and RMD relief, and a DIA for non-IRA money or more flexibility.

Neutral landscape
The shape of the question
The IRS is the main source because the QLAC rules define what a QLAC adds over a plain DIA.
Source trail: IRS: QLAC Rules (Form 1098-Q Instructions)
The RMD exclusion is the headline perk, on up to $210,000 of IRA premium for 2025 and 2026.
Source trail: IRS: QLAC Rules (Form 1098-Q Instructions)
The age-85 cap is the tradeoff, since QLAC income cannot be deferred past that point.

A plain DIA uses non-IRA money, which the SEC describes as a deferred annuity, with no RMD interaction.
