Exclusion Ratio
An exclusion ratio is the portion of each annuity payment that is treated as a tax-free return of the consumer's original investment, rather than taxable interest. The exclusion ratio applies only to non-qualified annuities (purchased with after-tax dollars). It is calculated at the start of the annuitization period using the consumer's original investment and the carrier's expected total return calculated under IRS-published mortality tables. The exclusion ratio applies until the consumer's original investment has been fully recovered; after that, 100% of each payment is taxable.
A 65-year-old uses $200,000 of after-tax money to purchase a SPIA paying $1,200 per month for life. The IRS-published life expectancy at age 65 is approximately 22 years. Expected total payments = $1,200 × 12 × 22 = $316,800. Exclusion ratio = $200,000 / $316,800 = 63.13%. Of each $1,200 monthly payment, $757.56 is treated as a tax-free return of premium and $442.44 is taxable interest. This continues for the consumer's actual life expectancy (22 years on the IRS table). After the original $200,000 has been fully returned, 100% of subsequent payments is taxable.
Why it matters
The exclusion ratio is the primary tax advantage of using non-qualified money to fund a SPIA. The carrier's gross monthly payment is reduced by the consumer's tax bill on the interest portion — but only on a fraction of each payment. For a consumer in a 22% federal bracket, the exclusion ratio reduces the effective tax on each SPIA payment from 22% to roughly 8% (22% × 36.87% = 8.1%).
How to evaluate
The exclusion ratio is determined automatically by IRS rules using the consumer's age, the premium amount, and the contract's payout structure. Qualified contracts (IRA, 401(k)) do not use the exclusion ratio — payments are fully taxable as ordinary income. Non-qualified contracts produce the most favorable exclusion ratio for younger annuitants (longer expected payout period) and life-only payouts (lower expected total payments increase the exclusion percentage).
In the contract
The carrier issues an annual Form 1099-R showing the taxable and non-taxable portions. The exclusion ratio is calculated by the carrier at the start of annuitization and disclosed in the contract's confirmation of annuitization.
