How much annuity you can buy depends on where the money is coming from. If you’re using after-tax savings to buy a non-qualified annuity, the IRS sets no limit at all; the ceiling is whatever the insurance company will accept, which for most carriers runs between $1 million and $5 million on a single contract before extra approval is required. If the annuity sits inside a retirement account, the IRS caps new contributions at $7,500 for an IRA or $24,500 for a 401(k) in 2026, with higher figures for older savers. Rollovers from existing retirement money don’t count against those caps.
No Federal Cap on Non-Qualified Annuities
An annuity bought with money that has already been taxed sits outside the IRA and 401(k) framework, so none of the federal annual contribution limits apply. Someone who sells a business, receives an inheritance, or has substantial savings can write a single check for hundreds of thousands of dollars, and the deposit is legal on the tax side. Only the growth inside the contract will eventually be taxed as ordinary income when withdrawn; the original deposit comes back out tax-free because it was already taxed on the way in.
That’s why the practical ceiling for most large annuity purchases isn’t a tax rule. It’s the carrier, the suitability review, and, indirectly, the state guaranty coverage limit.
Insurance Company Minimums and Maximums
Every carrier sets its own floor and ceiling. Single-premium contracts, where you deposit one lump sum, typically require between $10,000 and $25,000 to open. Flexible-premium contracts that accept ongoing deposits can start lower, often around $1,000 upfront with additional payments of $100 or more per month. The minimums exist because administering a contract costs money the insurer needs to recover on a reasonable balance.
At the top end, most carriers will accept between $1 million and $5 million on a single contract without special review. Above that range, the application goes to what the industry calls home office approval. Senior underwriters look at the insurer’s total exposure to you across every policy you hold with them, because a single large obligation can strain reserves. You should expect to provide a letter of intent explaining where the money came from and what you plan to do with the contract. The insurer may accept the risk, purchase reinsurance to offset it, or decline.
Carriers also impose maximum issue ages, usually between 75 and 95 depending on the product. A deferred annuity with a long accumulation phase generally has a lower age cutoff than an immediate annuity that starts paying right away, because pricing is built around life expectancy.
IRS Limits When the Annuity Is in a Retirement Account
When an annuity is held inside a retirement account, the account’s contribution limits apply. The annuity itself isn’t capped; the wrapper is.
IRA Annuities
An individual retirement annuity under Section 408 follows the same contribution rules as any traditional or Roth IRA.1Office of the Law Revision Counsel. 26 USC 408 – Individual Retirement Accounts For 2026, the limit is $7,500 if you’re under 50 and $8,600 if you’re 50 or older.2Internal Revenue Service. Retirement Topics – IRA Contribution Limits That cap covers all your IRAs combined. If you put $4,000 into a regular IRA, you have only $3,500 left to put into an IRA annuity that same year (under 50).
Annuities Inside a 401(k) or 403(b)
Some employer plans offer annuity options within the plan. For 2026, the standard employee contribution limit is $24,500. Savers 50 or older can add an $8,000 catch-up contribution, for a total of $32,500. Workers aged 60 through 63 qualify for a higher catch-up of $11,250 under the SECURE 2.0 Act, bringing their ceiling to $35,750.3Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500
Rollovers Don’t Count Against the Annual Cap
The annual limits apply only to new contributions. Rolling over money that’s already inside a retirement account is a different category. You can transfer $500,000 from a 401(k) into a qualified annuity without violating any contribution cap, because the IRS treats it as a continuation rather than a fresh deposit. This is how many retirees fund large qualified annuity purchases, consolidating old employer plan balances into a single annuity at retirement.
The distinction matters because exceeding the annual limit with new money triggers a 6% excise tax on the excess for every year it stays in the account.4Office of the Law Revision Counsel. 26 USC 4973 – Tax on Excess Contributions You can fix the mistake by withdrawing the excess before your tax filing deadline. Keeping records of what’s a rollover versus a fresh contribution prevents the problem in the first place.
The QLAC Cap for Longevity Annuities
A qualified longevity annuity contract is a deferred annuity purchased inside a retirement account that delays payments until later in life, often age 80 or 85. QLACs have their own purchase cap. For 2026, you can put up to $210,000 of your tax-deferred retirement savings into one.5Internal Revenue Service. Notice 25-67: 2026 Amounts Relating to Retirement Plans and IRAs The figure is indexed for inflation and applies across all your retirement accounts combined.
Before 2023, an additional rule capped QLAC purchases at the lesser of the dollar limit or 25% of your account balance. The SECURE 2.0 Act eliminated the percentage-of-balance restriction, so now only the flat dollar cap applies. If you have $300,000 in your IRA, you can use up to $210,000 for a QLAC. Money inside a QLAC is excluded from required minimum distribution calculations, which can lower taxable income in your 70s while locking in guaranteed income later.
1035 Exchanges From an Existing Annuity
If you already own an annuity and want to swap it for a different one, Section 1035 of the tax code allows a direct transfer with no tax consequences and no dollar limit.6Office of the Law Revision Counsel. 26 USC 1035 – Certain Exchanges of Insurance Policies You can exchange a $2 million annuity for a new $2 million annuity without triggering any gains. The contract owner must stay the same, so a 1035 exchange can’t be used to move an annuity to someone else.
The exchange doesn’t count as a new contribution, but the new carrier’s acceptance limits still apply. If the replacement carrier caps contracts at $1 million without home office approval, you’ll go through that review even though the money is coming from an existing annuity. Watch surrender charges on the old contract too, since moving money during the surrender period can cost several percentage points.
Suitability and Concentration Limits
Even when the IRS doesn’t cap the purchase and the carrier will take the money, state regulators add another layer. About 40 states have adopted rules based on the NAIC’s Suitability in Annuity Transactions Model Regulation, which requires agents and carriers to evaluate whether a purchase actually fits the buyer’s financial situation.7National Association of Insurance Commissioners. Annuity Suitability and Best Interest Standard The agent has to collect information about your income, existing assets, debts, and investment goals before completing the sale.
Concentration is one of the biggest suitability red flags. Many carriers won’t let you invest more than roughly half your liquid net worth in a single contract, though the exact threshold varies by company, age, and stated objectives. It isn’t a hard regulatory number so much as an industry practice carriers enforce to stay out of regulatory trouble. Liquid net worth for this purpose excludes your home and focuses on cash, investments, and other assets you could reach relatively quickly.
If the application fails suitability review, the carrier rejects it. Agents who push unsuitable sales face fines and license actions, and the company can be ordered to unwind the contract. In practice, this rule stops more large purchases than any tax code provision does.
Guaranty Association Coverage as a Soft Ceiling
Every state has a life and health insurance guaranty association that protects policyholders if the insurance company becomes insolvent. Under the NAIC model act, the standard annuity protection covers up to $250,000 in present value of annuity benefits per person, per failed company.8National Association of Insurance Commissioners. Chapter 6 – Guaranty Funds and Associations Some states set the figure higher or lower, with the range running from $100,000 to $500,000 depending on where you live.
That doesn’t technically limit how much you can buy, but it should shape how much you buy from any single carrier. If you put $750,000 into one annuity and the company fails, the amount above your state’s guaranty cap is at risk. Buyers investing large sums often spread the money across multiple carriers so each contract stays within the guaranty limit.
A Note on Medicaid Planning
If Medicaid long-term care eligibility is on your horizon, the annuity you buy has to meet specific federal requirements or the purchase can trigger a penalty period during which Medicaid won’t cover your care. To avoid that penalty, the annuity must be irrevocable and nonassignable, actuarially sound based on your life expectancy, and structured to pay in equal amounts with no deferral or balloon payment. The state must also be named as a remainder beneficiary so it can recover any Medicaid benefits paid on your behalf.9Office of the Law Revision Counsel. 42 USC 1396p – Liens, Adjustments and Recoveries, and Transfers of Assets A deferred annuity that delays payments to a future date will not qualify. No dollar cap applies, but the type and structure of annuity you can safely buy narrows sharply near eligibility.
