A purchased life annuity (PLA) is an insurance product you buy with your own savings, outside of any workplace pension, that converts a lump sum into a guaranteed income stream for the rest of your life. The key distinction is the funding source: because you paid for it with money that was already taxed, a portion of every payment you receive is treated as a return of your own capital and is exempt from income tax. That tax advantage is what separates a PLA from an annuity bought with pension funds, where the full payment is typically taxable as income.
How a Purchased Life Annuity Works
You hand an insurance company a lump sum of after-tax money. In return, the insurer promises to pay you a regular income, usually monthly, for as long as you live. The size of each payment depends on how much you invest, your age at purchase, current interest rates, and any optional features you add to the contract.
Once the annuity is set up, you generally cannot get your lump sum back. The insurer pools your money with that of other annuity holders and uses actuarial calculations to determine payment amounts. If you live longer than average, you come out ahead. If you die earlier than expected, the insurer keeps the remaining capital (unless you’ve chosen a feature that protects some of that value).
The Tax-Free Capital Element
This is the main financial advantage of a PLA. Because you bought the annuity with money you already paid tax on, the government doesn’t tax you again on the portion of each payment that represents your original capital being returned to you. Only the income element, essentially the interest or profit portion, is subject to income tax.
Your annuity provider handles the calculation. They determine what fraction of each payment counts as a tax-free return of capital and what fraction is taxable income. If you file a tax return, you report only the net taxable amount: total annuity payments minus the tax-free capital portion. Not every purchased life annuity qualifies for this split, so it’s worth confirming with your provider before you buy.
Compare this to an annuity purchased with pension savings. Because pension contributions typically went in before tax, the entire annuity payment is treated as taxable income. The PLA’s partial tax exemption can make a meaningful difference in your after-tax income, particularly if you have a large lump sum sitting in a taxable savings or investment account.
Who Typically Buys One
PLAs appeal most to people who have significant savings outside of their pension and want predictable, lifelong income. Common buyers include retirees who have already maximized their pension options, people who received an inheritance or sold a property, and anyone who wants to eliminate the risk of outliving their money.
There is no strict legal minimum age for purchasing an annuity. Most people can buy one at 18 or older. In practice, though, many insurance companies set their own age windows, often requiring buyers to be at least 50 and capping eligibility somewhere between 75 and 95. The older you are when you buy, the higher your payments will be, since the insurer expects to pay you for fewer years.
Payment Options and Features
A basic PLA pays a fixed amount each month until you die, then stops. But most providers offer features (sometimes called riders) that adjust how the annuity behaves. These come at a cost, typically a lower monthly payment, but they add flexibility or protection.
- Joint-life option: Payments continue after your death for the lifetime of a surviving spouse or partner. The monthly amount is usually lower than a single-life annuity because the insurer may be paying out for two lifetimes.
- Guarantee period: Payments are guaranteed for a minimum number of years (commonly 5 or 10), even if you die during that period. If you pass away in year three of a 10-year guarantee, your beneficiary receives the remaining seven years of payments.
- Capital protection (refund feature): If you die before the total payments you’ve received equal the lump sum you originally invested, your beneficiary gets the difference back. This protects against the scenario of dying shortly after purchase and “losing” your capital.
- Inflation-linked payments: Instead of a fixed payment, the amount increases each year by a set percentage or in line with an inflation index. Payments start lower than a fixed annuity but grow over time, helping preserve your purchasing power.
Every feature you add reduces your starting income. A single-life, level-payment annuity with no guarantees will always offer the highest initial payout. Deciding which features are worth the trade-off depends on your health, whether you have dependents, and how much other income you can rely on.
What Determines Your Payment Amount
Several factors drive the size of your annuity income:
- Lump sum invested: More money in means more income out.
- Your age: Older buyers get higher payments because the insurer expects to make fewer of them.
- Interest rates: Annuity rates closely track long-term bond yields. When rates are high, annuity payouts are more generous.
- Health status: Some providers offer enhanced annuity rates if you have a health condition that reduces your life expectancy. Smokers, for example, often qualify for higher payments.
- Features selected: Joint-life coverage, guarantee periods, and inflation linking all reduce the starting payment.
Because rates vary between insurers, shopping around is essential. The difference between the best and worst quotes for the same lump sum can be substantial.
Key Trade-Offs to Understand
The biggest benefit of a PLA is certainty. You receive guaranteed income for life regardless of what happens in financial markets, and a portion of that income is tax-free. The insurance company bears the investment risk and the longevity risk. For someone worried about running out of money in retirement, that peace of mind has real value.
The biggest drawback is irreversibility. Once you hand over your lump sum, you typically cannot get it back. If you need a large amount of cash for an emergency, the annuity won’t help. Annuities have significantly less liquidity than keeping the same money in a savings account or investment portfolio.
Inflation is another concern. A fixed-payment annuity that feels generous today may feel tight 15 or 20 years from now as prices rise. You can address this with an inflation-linked option, but you’ll start with a noticeably smaller payment.
There’s also counterparty risk. Your income is only as secure as the insurance company paying it. In the United States, state guaranty associations provide a safety net if an insurer fails, but coverage limits vary. Choosing a financially strong, highly rated insurer matters.
PLA Compared to a Pension Annuity
The mechanical structure is similar: both convert a lump sum into lifetime income. The differences come down to funding source and tax treatment. A pension annuity is purchased with money from a workplace pension or other retirement account, where contributions were typically made before tax. Because the money went in untaxed, the full annuity payment is taxable income.
A PLA is funded with after-tax savings from outside the pension system. Because you already paid tax on that money, you get the capital element back tax-free. If you have savings in both pension accounts and taxable accounts, understanding this distinction helps you plan which pot of money to annuitize for the best after-tax result.
