Short answer: no, an annuity does not reduce your Social Security benefit. The check Social Security sends you is figured from your earnings record and the age you claim. Income from a single premium immediate annuity never enters that calculation, before or after full retirement age. In our October 2026 rate tables, $100,000 buys a 65-year-old man up to $693 a month for life (best of 8 carriers, single life, 5-year period certain) and a woman the same age up to $658, and neither figure takes a dollar off a Social Security payment.
Source: LifeAnnuities.us quote surveys run for real clients. 54 base survey runs received and 52 used for pricing (July 14 to September 14, 2026), checked against 7 new survey runs (September 18 to 29, 2026): 1 of 8 published carriers repriced, 7 held. Joint figures at ages 65 and 70 are calibrated to a direct same-age joint quote. Single life or joint (100% to survivor), 5-year period certain, per $100,000. How we build these figures.
Where annuity income does count is in three other places: the tax on your Social Security benefits, the surcharge on Medicare Part B and Part D premiums, and needs-based programs like SSI and Medicaid. Whether the annuity was bought with IRA money or after-tax savings changes the result in the first two; SSI counts the whole check either way. This guide walks through all three with the same $100,000 example.
Why an Annuity Does Not Reduce Your Social Security Check: The Earnings Test
The only rule that ever lowers a retirement benefit because of income is the retirement earnings test, and it applies only to people who claim before full retirement age and keep working. Social Security is specific about what goes into it. On its Receiving Benefits While Working page (read October 6, 2026), the agency says it counts "only the wages you make from your job or your net profit if you're self-employed," and then lists what it leaves out: "We don't count pensions, annuities, investment income, interest, veterans benefits, or other government or military retirement benefits."
For 2026, the test withholds $1 of benefits for every $2 of earnings above $24,480 if you are under full retirement age all year, and $1 for every $3 above $65,160 in the months before you reach full retirement age during that year. From the month you reach full retirement age there is no limit at all.
So a 63-year-old who claimed early, stopped working, and then bought a SPIA has nothing to reconcile. The annuity check and the Social Security check arrive side by side. The same is true at 70. Annuity income is unearned income in Social Security's vocabulary, and unearned income is simply not part of the test.
Does Annuity Income Make Your Social Security Benefits Taxable?
This is the interaction people usually mean when they ask whether an annuity "affects" Social Security. The benefit is not reduced, but more of it can become taxable.
IRS Publication 915 (2025 edition, read October 6, 2026) runs the test on one number: half of your Social Security benefits plus all your other income, including tax-exempt interest. For a single filer, head of household or qualifying surviving spouse, up to 50% of benefits are taxable once that total passes $25,000, and up to 85% once it passes $34,000. For a married couple filing jointly the two lines are $32,000 and $44,000. The publication's own worked example includes "a fully taxable pension" in other income, and the taxable part of an annuity payment is treated the same way.
The words taxable part are the whole story here, so take the $693 a month from the first paragraph and follow it through.
$100,000 at 65: what actually enters the formula
$693 a month is $8,316 a year. How much of that counts depends on what kind of money bought the annuity.
Non-qualified money (after-tax savings). Part of every payment is a return of your own premium and is not taxed. The split comes from the exclusion ratio in IRS Publication 939 (Rev. December 2025): investment in the contract divided by expected return, where expected return is the annual payment times a life-expectancy multiple from the publication's Table V. At 65 that multiple is 20.0. So $8,316 times 20.0 is an expected return of $166,320, and $100,000 divided by $166,320 is about 60%. Roughly 60% of each check is excluded and roughly $3,300 a year is ordinary income. That $3,300 is what enters the Social Security formula. (The 5-year period certain trims the ratio by a fraction of a point through a refund-feature adjustment; the exclusion ratio guide works that step and has a calculator. This is an illustration on our table figure, not a quote and not tax advice; the carrier's Form 1099-R governs what you report.)
IRA or 401(k) money. There is no exclusion ratio. Every payment is a distribution from a retirement account, so the full $8,316 enters the formula. This is not a small case: 24 of the 65 quote survey runs we have received since July 14, 2026 were for IRA money, so many of the people we quote are in it. See buying an annuity with IRA money for how the purchase and the required minimum distributions work.
A worked example
Suppose a single filer collects $24,000 a year of Social Security and has $15,000 of other taxable income (a small pension, some IRA withdrawals, interest). These are round assumptions for the arithmetic, not averages. Before any annuity, the test number is half of $24,000 plus $15,000, or $27,000: above the $25,000 line, so up to half of the benefits are already taxable, but below $34,000.
| $100,000 SPIA at 65, $693 a month | Enters the formula | Test number | Band |
|---|---|---|---|
| No annuity | $0 | $27,000 | Up to 50% taxable |
| Non-qualified SPIA (about 60% excluded) | about $3,300 | about $30,300 | Still up to 50% taxable |
| IRA-funded SPIA | $8,316 | $35,316 | Up to 85% taxable |
The non-qualified version stays under the $34,000 line; the IRA version crosses it. Crossing a line means a larger share of the benefit is counted on your return, not that the benefit is cut. How much extra tax that produces depends on your bracket, so read the annuity tax guide and talk to your own preparer before you buy.
One more thing worth knowing: the exclusion ratio runs out. Publication 939 caps the total you can exclude over the years at your net cost, so once the tax-free portions add up to your premium (after roughly the Table V number of years), every later payment is fully taxable and the non-qualified row starts to look like the IRA row.
Medicare Part B and Part D Premiums (IRMAA)
The second place annuity income counts is the income-related monthly adjustment amount on Medicare premiums. The CMS fact sheet of November 14, 2025 sets the 2026 Part B standard premium at $202.90 a month. The first surcharge tier begins when modified adjusted gross income is above $109,000 on an individual return or $218,000 on a joint return: Part B rises by $81.20 to $284.10, and Part D carries an extra $14.50. Together that first step is about $1,148 a year per person. Higher tiers follow at $137,000, $171,000, $205,000 and $500,000 on an individual return ($274,000, $342,000, $410,000 and $750,000 on a joint return).
Three details decide whether an annuity matters here. First, the income measure. Social Security's operating manual (POMS HI 01101.010) defines MAGI for this purpose as adjusted gross income plus tax-exempt interest, so the taxable part of your annuity is in and the excluded part is out, exactly as with the benefit tax. Second, the lookback. The same section says 2026 premiums "are generally based on 2024 tax return information." An annuity you start this year shows up in the premium two years from now. Third, the cliff. IRMAA tiers are steps, not a slope: one dollar over a line costs the whole surcharge for that year.
For most buyers of a $100,000 SPIA this is a non-issue. Adding about $3,300 (non-qualified) or $8,316 (IRA) to income only matters if you were already within that distance of $109,000 or $218,000. A large IRA annuitization is different. Moving $300,000 of IRA money into a SPIA at 65 pays about $2,079 a month, or about $24,948 a year, every dollar of it taxable (scaled from the per-$100,000 figure; a real quote at that premium can differ a little). That is enough to carry a household from comfortably under the first line to over it. The purchase itself, done as a direct transfer inside the IRA, is not the taxable event; the payments are, and they keep coming. If you are near a line, the fix is usually sizing the annuity, splitting it between qualified and non-qualified money, or timing it against other withdrawals, all of which are quote-stage conversations.
SSI and Medicaid
The third place is the one where annuity income can truly reduce a benefit, and it is a different program from Social Security retirement. Supplemental Security Income is needs-based. Social Security's manual (POMS SI 00830.160, effective August 7, 2024) states that "annuities, pensions, retirement benefits, and disability benefits are unearned income," and the 2026 edition of Understanding SSI shows how unearned income works: after a $20 general exclusion, each dollar of countable income comes off the federal SSI payment. Its 2026 examples run the subtraction from a $994 federal benefit rate for an individual. On that rate, a $693 monthly annuity check counts as $673, about 68% of the rate, and leaves $321 of SSI on its own; add a Social Security retirement check of more than $321 a month and the SSI payment is gone.
Medicaid is administered by each state, and the income and asset rules differ by state, including how an annuity's payments and its remaining value are treated. We do not give advice on either program. If you or the person you are buying for receives SSI or Medicaid, or might need Medicaid for long-term care, talk to an elder-law attorney or benefits counselor in your state before an annuity is bought in that person's name. Our spendthrift trust vs annuity guide covers the related case of an adult child on benefits.
The Bridge Case: A SPIA From 62 to 70
If you plan to live on an annuity while you delay Social Security, the annuity does not get in the way of the delay. The delayed retirement credits are 8% for each year past full retirement age for anyone born in 1943 or later, stopping at 70, and nothing about your other income changes that. The annuity simply funds the wait.
What $100,000 buys at the ages that matter for a bridge, from our October 2026 tables, single life with a 5-year period certain, best of 8 carriers: about $667 a month at 62, $693 at 65 and about $723 at 67. The 65 figure is read at a surveyed age in an earlier round, then repriced; 62 and 67 are not table ages and are straight-line estimates between the 60, 65 and 70 figures, so treat them as a guide to the shape, not a quote. You can see every carrier at 65 on the age 65 rates page.
The interaction to watch during a bridge is the tax one above, and it points the other way from what people expect. While you are delaying, you have no Social Security benefit to tax, so the annuity's taxable part is just ordinary income with nothing to push over a threshold. The combined-income test only starts to bite at 70 when the larger benefit begins. The annuity vs Social Security guide covers the bridge strategy itself, including a period-certain annuity that stops the month the bigger benefit starts, and the $100,000 annuity guide shows the payout at every age.
Married Couples: A Joint Annuity and Social Security
A married couple runs the two tax tests on a joint return, with the $32,000 and $44,000 benefit-tax lines and the $218,000 IRMAA line. The annuity they usually buy is joint and survivor, which pays as long as either spouse lives. In our October 2026 tables the best joint figure at 65, both spouses the same age and 100% continuing to the survivor, is $608 a month per $100,000. That figure is derived by ratio, then calibrated to a direct same-age joint quote (both spouses 66) from the latest round. The joint rate tables show all 8 carriers.
The reason the joint figure matters for a Social Security plan is what happens at the first death. A couple's Social Security income usually falls at that point; the survivor rules are on ssa.gov and depend on each spouse's record. A joint annuity does not fall. For many couples the annuity is the piece that keeps the survivor's budget whole, and the survivor's tax picture also changes: a single filer's thresholds are lower than a couple's, so the same annuity income counts harder in year two of widowhood. Our annuities for couples guide covers how to structure a joint purchase, and the joint and survivor guide compares the 100%, 75% and 50% versions and what each costs in monthly income.
Checklist Before You Buy
- Qualified or non-qualified money? This single choice decides whether $8,316 or about $3,300 a year (per $100,000 at 65) enters every formula on this page. If you have both kinds of savings, the split is worth a conversation.
- Filing status. Single, joint, and married filing separately each have different benefit-tax and IRMAA lines. A widow or widower moving to single status should run the numbers on the new lines.
- Where you sit against the $34,000 or $44,000 line today. If you are already past it, extra annuity income cannot push more than 85% of your benefit into taxable income.
- Your current IRMAA tier and your distance from the next one. Remember the two-year lookback: income in 2026 sets 2028 premiums.
- State income tax. Some states tax annuity income, some exempt part of it, and some have no income tax. The state taxes on annuities guide covers all 50.
- Anyone in the household on SSI or Medicaid. Stop and get benefits advice first.
Questions People Ask About Annuities and Social Security
Does annuity income reduce my Social Security check?
No. Social Security only reduces a retirement benefit for earnings from work, and only before full retirement age. The Social Security Administration says it does not count pensions, annuities, investment income or interest in that test. A SPIA paying $693 a month on $100,000 at 65 (our October 2026 tables, best of 8 carriers) leaves the benefit itself exactly where it was.
Does annuity income count toward the earnings test before full retirement age?
No. The earnings test counts wages and net self-employment income, including bonuses, commissions and vacation pay. In 2026 the limit is $24,480 for someone under full retirement age all year. Annuity payments are unearned income and are left out of the test entirely, so a 63-year-old can collect both a reduced Social Security benefit and a SPIA check in full.
Will an annuity make my Social Security benefits taxable?
It can, because the taxable part of each annuity payment counts in the formula that decides how much of your benefit is taxed. For a single filer, up to 50% of benefits become taxable once half your benefits plus other income passes $25,000, and up to 85% above $34,000 (joint filers: $32,000 and $44,000). A non-qualified SPIA adds only its taxable slice; an IRA-funded SPIA adds every dollar.
Does an annuity raise my Medicare premium?
Only if it pushes your modified adjusted gross income over an IRMAA threshold. For 2026 the first surcharge begins above $109,000 for a single filer and $218,000 for a joint return, based on your 2024 tax return. A $100,000 SPIA at 65 adds about $3,300 a year of taxable income if bought with after-tax money, or $8,316 if bought with IRA money; a large IRA-funded annuity can add enough to cross a line, two years later.
Does it matter whether the annuity was bought with IRA money?
Yes, more than anything else on this page. Payments from an IRA-funded SPIA are fully taxable IRA distributions, so the whole $8,316 a year at 65 enters the Social Security and Medicare formulas. A SPIA bought with after-tax savings excludes about 60% of each payment as a return of your own money, leaving roughly $3,300 a year that counts.
Does an annuity affect SSI or Medicaid?
Yes. Supplemental Security Income treats annuity payments as unearned income, and after a $20 monthly exclusion each dollar comes off the $994 federal benefit rate for an individual (2026). Medicaid income and asset rules are set state by state. If you or a family member relies on either program, talk to an elder-law or benefits adviser before buying an annuity that pays that person directly.
Bottom Line
An annuity leaves your Social Security check alone. What it can change is how much of that check is taxed and, for larger IRA purchases, what you pay for Medicare, and both of those depend far more on which account the premium comes from than on the annuity itself. Run your own figure through the payout calculator, then request a free multi-carrier SPIA quote. When Phil Barker runs your quote across the carriers, tell him which account the money is in and whether you are near a threshold; the quote can be sized and split with that in mind, and each carrier's illustration shows the taxable and tax-free portion to take to your own adviser.
