If you're already receiving Social Security or planning to claim soon, there are three big changes to Social Security that you need to know about. These changes impact how much you'll receive in your bank account each month and how other income may affect your monthly benefits.

Cost-of-living adjustments, earnings rules, and Medicare premiums are all shifting in ways that could quietly reduce your retirement income. Here are the three biggest Social Security changes in 2026 and why they matter to your retirement plan.

2026's COLA may disappoint some retirees

Each year, Social Security benefits are adjusted through a cost-of-living adjustment (COLA). For 2026, you'll receive an increase in your Social Security deposit of 2.8%. While the average Social Security check is $2,071 in 2026, the actual dollar increase you'll get is based on your work history, when you claimed, and other factors.

While there have been large increases in previous years, inflation has cooled off. A lower inflation rate is good for your expenses, but it also means that your annual increase in Social Security benefits will be smaller. For some seniors, the lower COLA number could be a disappointment.

In particular, retirees relying on Social Security for most of their income, households facing rising costs in health care, insurance, or housing, or anyone who hasn't adjusted their budget since inflation slowed will be the most impacted.

A smaller COLA still raises your benefit, but it may not fully cover increases in essential expenses, especially medical costs. This gap often surprises retirees who assume COLAs are designed to keep pace with real-world spending.

Earnings limits are increasing, but the rules still catch people off guard

If you collect Social Security before reaching full retirement age and continue working, the earnings limit still applies in 2026. While the income threshold has increased each year, the rule itself hasn't changed.

Most working retirees can exempt up to $24,480 per year. That number increases to $65,160 in the year you reach full retirement age. These amounts increased by $1,080 (4.6%) and $3,000 (4.8%), respectively.

Any money you earn above these limits reduces your Social Security benefits. For those under full retirement age, your benefit is reduced by $1 for every $2 you earn. In the year you reach full retirement age (until the month before your birthday), it's reduced by $1 for every $3 of income.

This reduction in benefits is a double-whammy to your retirement income. Not only will filing early reduce your monthly benefit by up to 30%, but the earnings limit will reduce it even more if you continue to work. The good news is that the deductions stop once you reach full retirement age.

If you don't plan your income carefully, you may see unexpected reductions in monthly checks, even though those benefits are later recalculated. Many retirees don't realize this adjustment isn't permanent, but it still impacts how much you receive each month during your early retirement years.

Medicare premiums can offset Social Security increases

When you retire, most people stop receiving medical insurance through their employer. Instead, you turn to Medicare and Medicare supplements for health care insurance.

Medicare Part B and Part D premiums are typically deducted directly from your Social Security check. However, when premiums increase faster than COLAs, your net benefit can shrink depending on the size of your Social Security benefit, even in years with a positive COLA.

Heading into 2026, Medicare premiums are continuing to adjust based on health care costs. In 2026, Part B premiums are increasing to $202.90 per month, up from $185 in 2025. Additionally, higher-income retirees may face income-related monthly adjustment amount (IRMAA) surcharges that raise their premiums even more.

Many retirees focus on their gross Social Security benefit and overlook how Medicare premiums affect how much is actually deposited into their bank accounts. That disconnect can create budget stress if you're not reviewing premium notices each year.

Bottom line

None of these changes is significant by itself. But the combined impact can affect how you generate retirement income. Smaller COLAs, earnings limits for working seniors, and Medicare deductions can alter your retirement strategy.

Don't just set your Social Security strategy on autopilot. Review your benefit statements to understand how upcoming changes affect your Social Security benefits. Rising Medicare premiums and health care expenses can negate the increase in your monthly income. If you're an early retiree who is still working, pay attention to retirement earnings tests to ensure you stay under the limit to avoid reductions in your retirement benefits.
