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 as you plan: 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 projected last year. 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 them in step 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, based on July, August, and September Consumer Price Index data. Current forecasts point to an increase in the range of 3.5% to 3.6%. The Senior Citizens League (TSCL) pegged its July estimate at 3.6%, while AARP projected 3.5% in its own concurrent update. Either figure would represent the largest annual COLA since 2023, a meaningful step up from recent years.

A larger COLA sounds like good news, and it does mean bigger monthly checks. The catch is that the adjustment is tied directly to inflation, so a higher COLA signals that the prices seniors pay for groceries, healthcare, and housing have also climbed. Retirement savings and other fixed-income sources are not automatically inflation-proofed, which means surging prices can quietly erode overall purchasing power even as the Social Security check grows. Seniors should plan now for both the potential income bump and the higher costs that tend to accompany it.

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 for wage growth, and 2027 will bring higher thresholds than 2026.

Under 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 no longer applies and there is no cap at all. It is also worth noting that withheld benefits are not lost forever: at FRA, Social Security recalculates the benefit to credit those missed payments, though the interim cash-flow impact is real.

In 2027, both thresholds will rise. Retirees who are still working and collecting benefits below FRA can use this as an opportunity to revisit their work schedules and earnings strategies before the new year.

3. Eligibility for Social Security benefits will require higher earnings

This change affects current workers more than current retirees, but it is worth understanding for anyone still building their earnings record.

To qualify for Social Security retirement benefits, a worker needs 40 credits accumulated 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. For workers in low-wage or part-time positions who are close to earning exactly four credits per year, even a modest shortfall could 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, nearly a 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 in 2027, an increase of roughly $6.60 or about 3.25%. The official 2027 premium will be confirmed by the Centers for Medicare and Medicaid Services in November 2026, and some private forecasters estimate it could land between $215 and $219 given a recent pattern of trustee projections undershooting the final figure.

Because most retirees have Medicare premiums deducted directly from their Social Security checks, any premium increase reduces the net benefit of the COLA before it reaches their bank accounts. The hold-harmless provision does protect most beneficiaries from seeing their net monthly check shrink if the 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. Planning for the premium increase now, alongside the expected COLA, gives a clearer picture of what the actual 2027 take-home benefit will look like.

A financial advisor can help you model all four of these changes together so you are ready when 2027 arrives.
