7 Social Security Rules Every Retiree Needs to Know

Full analysis

Devin Carroll and John Ross walk through seven Social Security rules that even well-prepared retirees often get wrong — covering how benefits are calculated, the earnings test, taxation, cost-of-living adjustments, spousal coordination, survivor-benefit filing strategy, and divorce rights. The episode is practical and specific; it's worth 40 minutes if any of those topics touch your situation.

What was covered

• Benefit calculation: 35 highest indexed years. Your benefit is based on your highest 35 years of earnings, adjusted for inflation using SSA's indexing factors — not your last few years or a simple average. Fewer than 35 years of earnings means zeros fill the gaps and pull your benefit down. Carroll recommended checking your earnings record annually at ssa.gov to catch errors, especially if you've changed your name.

• The earnings test before full retirement age (FRA). If you collect Social Security while still working and haven't reached FRA, benefits are withheld once earnings exceed a threshold (Carroll placed it "in that $25,000 mark," roughly tripling in the year you hit FRA). Carroll said he has yet to find a case where filing while subject to the limit makes sense, mainly because it opens the door to SSA overpayment notices that are notoriously hard to resolve. Any withheld benefits are recalculated at FRA as if you filed later — so the money isn't lost, just deferred.

• Taxation of benefits: up to 85%, not all. Neither extreme is correct — benefits are not tax-free, nor is the full benefit taxed. The formula adds all income plus half of Social Security ("provisional income") to determine what share — up to 85% — is included in taxable income. Qualified Roth IRA distributions do not count as income in that formula, so heavy Roth users can keep a large portion of their benefit tax-free.

• Cost-of-living adjustments (COLA) and the PROMISE Act. COLA is tied to the CPI-W. Carroll noted that Medicare Part B premium increases often eat most of the raise, especially for lower-benefit recipients. He flagged a legislative proposal (the PROMISE Act) that would force a floor vote on Social Security reform — including a proposal to convert COLA to a flat-dollar increase based on the 20th-percentile benefit, which one study Carroll cited said would close 56% of the program's long-term shortfall. He cautioned not to count on generous annual increases, particularly for higher-benefit recipients.

• Married couples must coordinate filing. A break-even calculation that looks only at your own benefit ignores the survivor picture. When one spouse dies, one Social Security check disappears; expenses don't drop proportionally; and the survivor files taxes as a single person, often pushing required minimum distributions (RMDs) into a higher bracket. Carroll said failing to analyze both benefits jointly is a planning error "period."

• Survivor benefits have separate filing rules. Unlike spousal benefits (where filing for one triggers filing for all), survivor benefits can be claimed independently. You can file for a survivor benefit as early as age 60, collect it while your own benefit grows with delayed credits, then switch to your own benefit at 70 — or reverse the sequence. Carroll noted SSA staff themselves sometimes get this wrong and advise incorrectly.

• Divorce and Social Security: your job to know. SSA will not walk you through your full marital history at the claims window. If a marriage lasted at least 10 years and you are currently unmarried, you may be eligible for a divorced-spouse or divorced-survivor benefit — even from an ex who has died. Carroll advised keeping a file with marriage and divorce dates and any death records for all prior spouses. Multiple ex-spouses collecting off your record do not reduce your own benefit.

Notable claims & predictions

• Devin Carroll: "I have not yet found a case that I can think of off the top of my head where it makes sense to file if the earnings limit is going to apply." Filing anyway invites SSA overpayment notices — he called that the number one reason to stay out until you clear the threshold.

• Devin Carroll on Roth and taxes: "If you have $5 million in a Roth IRA and you're taking out $200,000 a year…and you get Social Security, your Social Security is tax free, too." Under current law, qualified Roth distributions don't count as provisional income.

• Devin Carroll on COLA reform: Flattening COLA to a fixed dollar amount pegged to the 20th-percentile benefit "would fix…56% of the long-term shortfall." He compared that impact to eliminating the taxable wage cap entirely.

• Devin Carroll on the "claim at 62 and invest" advice: "I don't think 8 years' time value of money is going to be enough to catch up to a benefit that is at that point going to be around 75% larger" — meaning the strategy fails as an income-replacement plan, though it might make sense as a pure wealth-transfer strategy if you'd never spend the proceeds.

• John Ross on survivor benefits: A woman in a Facebook group said she was "so mad" discovering she'd left years of survivor benefits unclaimed simply because she hadn't known the early-filing rule — age 60 rather than 62 — applied. Ross and Carroll agreed SSA staff routinely give wrong guidance on this.

Fact check

Carroll's "around $25,000" earnings-test threshold — Accurate in the general vicinity. The exact annual limit adjusts each year; verify the current figure at ssa.gov before making a filing decision, since a stale number could lead you to file when you shouldn't. Carroll's broader point (don't file while subject to the limit) stands regardless of the precise figure.

Carroll's claim that 56% of the long-term shortfall would be closed by flattening COLA — Unverified. Carroll could not name the study or its author. This is a significant number used to frame a policy argument; without knowing the methodology, the modeling assumptions, or who funded the analysis, treat it as a rough illustration rather than a reliable projection.

Carroll's "75% larger" benefit at 70 vs. 62 — True in the right ballpark. The standard delayed-credit math (early reduction at 62 plus delayed credits to 70) does produce roughly a 75–77% gap relative to the age-62 benefit for someone at FRA 67. His conclusion — that eight years of investment returns on a reduced benefit are unlikely to match the guaranteed internal growth — is directionally sound, though the precise break-even depends on actual returns, taxes, and spending plans.

Carroll's claim that survivor benefits can be filed at 60, own benefits at 62 — Correct. The ability to file separately for survivor benefits versus retirement benefits, and to switch between them, is a real and often overlooked rule. His warning that SSA staff sometimes misstate this is consistent with widely reported consumer experiences.

Carroll's point that multiple ex-spouses collecting spousal benefits don't reduce your own benefit — Correct. SSA pays divorced-spouse benefits from its own funds; they do not come out of the worker's benefit.

Why this matters for you

• Check your earnings record now. Log into ssa.gov and review your year-by-year earnings history. Errors — including years showing zero — are not uncommon and can silently reduce your benefit for life. If you've changed your name at any point in your career, pay special attention to years around that change.

• If you're married, run the survivor scenario. Before deciding when to file, model what happens to the household income — and the tax bracket — when one of you dies. The one-benefit-disappears scenario often argues for the higher earner to delay as long as possible, maximizing what the survivor will collect.

• If you're divorced after a marriage of 10 or more years, build your file. Gather marriage certificates, divorce decrees, and — if an ex has died — any available death documentation. SSA will not prompt you; the burden is on you to raise the claim. This applies even if your ex has remarried, and even if you've had multiple qualifying marriages.

• Don't take the "claim early and invest" advice at face value. The math generally favors delayed claiming for anyone who expects to spend the money and live into their mid-80s or beyond. The strategy may make sense in narrow circumstances (terminal illness, purely bequest-driven planning) — but those are exceptions, not the rule the social-media reel implied.
