4 Social Security Changes Retirees Need to Start Preparing for in 2027

Changes to Social Security can have a significant impact on your finances in retirement. Most seniors rely on the program for at least part of their income, so when the rules shift, older Americans need a plan. The four changes below are already taking shape for 2027, and the earlier you understand them, the better positioned you will be when January arrives.

One piece of broader context is worth keeping in mind: the 2026 Social Security Trustees Report, released June 9, 2026, projects that the Old-Age and Survivors Insurance (OASI) trust fund will exhaust its reserves in the fourth quarter of 2032, one quarter earlier than the prior year’s estimate. If Congress does not act before then, ongoing payroll-tax revenue would cover only about 78% of scheduled benefits. That long-term picture makes near-term planning all the more important.

1. Retirees will get a Cost of Living Adjustment

The Social Security cost-of-living adjustment (COLA) is typically the change retirees follow most closely. COLAs increase retirement benefits to keep pace with inflation, and 2027 looks set to bring a notably larger raise than 2026’s 2.8% adjustment.

The official 2027 COLA will be announced on October 14, once the Bureau of Labor Statistics releases September’s Consumer Price Index data, completing the July, August, and September readings the Social Security Administration needs for its calculation. Current forecasts put the increase in the 3.5% to 3.6% range. AARP now projects 3.6%, while the Senior Citizens League (TSCL) revised its estimate down slightly to 3.5% after August inflation data came in. Either figure would represent the largest annual COLA since 2023, a meaningful step up from the recent run of smaller adjustments.

A higher COLA does mean bigger monthly checks. The average retired worker received about $2,086 per month as of July 2026, meaning a 3.5% increase would add roughly $73 a month starting in January. The catch is that the adjustment tracks the prices seniors already paid over the summer, so a higher COLA signals that groceries, healthcare, and housing costs have climbed right along with it. In fact, TSCL’s most recent buying-power study found that compared with 2016, Social Security benefits are worth only about 86.3 cents on the dollar. Retirement savings and other fixed-income sources do not adjust automatically, which means rising prices can quietly erode overall purchasing power even as the monthly check grows.

2. Seniors will be allowed to earn more money

Retirees collecting Social Security before reaching their full retirement age (FRA) face an earnings test: earn too much and part of the monthly benefit is temporarily withheld. Those limits adjust most years alongside wage growth, and 2027 will bring higher thresholds than 2026.

Under current 2026 rules, retirees who will not reach FRA at any point during the year can earn up to $24,480 before losing $1 in benefits for every $2 above that ceiling. Retirees who will reach FRA during 2026 face a higher limit of $65,160, above which $1 is withheld for every $3 earned. Once a retiree hits FRA, the earnings test disappears entirely and there is no cap at all. Withheld benefits are not permanently lost: at FRA, Social Security recalculates the benefit to credit those missed payments, though the interim cash-flow impact is real.

Both thresholds will rise in 2027. Retirees who are still working and collecting benefits below FRA can use the months ahead to revisit their work schedules and income strategies before the new year.

3. Eligibility for Social Security benefits will require higher earnings

This change touches current workers more than current retirees, but it matters for anyone still building their earnings record.

To qualify for Social Security retirement benefits, a worker must accumulate 40 credits over a career, with a maximum of four credits available per year. In 2026, earning one credit requires $1,890 in covered wages, meaning a worker needs at least $7,560 in annual earnings to collect all four credits for the year. Because the credit threshold rises each year alongside average wages, the 2027 figure will be higher still. For workers in low-wage or part-time positions who are close to earning exactly four credits per year, a modest shortfall can matter. Checking your earnings record through a my Social Security account at SSA.gov is the simplest way to confirm you are on track.

4. Medicare premiums could take a bigger bite out of Social Security checks

Medicare Part B premiums jumped sharply in 2026, rising from $185 to $202.90, a nearly 10% increase. The outlook for 2027 is more restrained. The 2026 Medicare Trustees Report projects the standard Part B premium will rise to approximately $209.50 per month, an increase of about $6.60 or 3.25%. For context, the prior year’s trustees report had put the 2027 premium at $218.60, so the newer projection is actually a welcome downward revision. The official 2027 premium will be set by the Centers for Medicare and Medicaid Services in November 2026. Some private forecasters estimate the final number could land between $216 and $219, citing a recent pattern of trustee projections undershooting the actual figure. The annual Part B deductible is also projected to rise, from $283 in 2026 to roughly $292 in 2027.

Because most retirees have Medicare premiums deducted directly from their Social Security checks, any premium increase reduces the net benefit of the COLA before the money reaches their bank accounts. The hold-harmless provision does protect most beneficiaries from seeing their net monthly check shrink when a Part B premium increase exceeds the COLA, but it does not prevent the premium from absorbing a significant portion of the raise. Higher-income retirees subject to Income-Related Monthly Adjustment Amount (IRMAA) surcharges do not receive that same protection. Modeling the expected COLA alongside the likely premium increase now gives a clearer picture of what the actual 2027 take-home benefit will look like.

A financial advisor can help you work through all four of these changes together so you are fully prepared when 2027 arrives.

Editor’s note: This article was updated to reflect the most current COLA projections, with AARP now forecasting 3.6% and TSCL revising to 3.5% after August 2026 CPI data; the average retired-worker benefit of approximately $2,086 per month as of July 2026 and the roughly $73 monthly dollar impact of a 3.5% COLA; TSCL’s finding that benefits have lost about 13.7% of purchasing power since 2016; the prior-year trustees projection of $218.60 for the 2027 Part B premium versus the current $209.50 estimate; updated private-forecaster estimates of $216 to $219 for the Part B premium; and the projected 2027 Part B deductible of $292.
