Social Security plays a major role in millions of Americans' retirement finances. After years of paying Social Security payroll taxes, it's a nice financial safety net in retirement when income sources could be more limited than in your working years.

Considering how important Social Security is for many, it makes sense that you'd want to maximize your monthly benefit as much as possible. In 2025, the maximum monthly Social Security benefit is $5,108. If that has a nice ring to it, and you want to set your sights on receiving the maximum benefit, there are two things you need to ensure happen in 2025.

You'll need to earn above the wage base limit

Most Americans pay Social Security payroll taxes on all their earned income up to a certain yearly limit, called the "wage base limit." Income earned above the wage base limit is not subject to Social Security payroll taxes, so it's also not considered when calculating monthly benefits.

The wage base limit is important because you need to earn at least that amount in the 35 years that Social Security will use to calculate your monthly benefit.

The wage base limit in 2025 is $176,100, so if 2025 will be one of the years used to determine your monthly Social Security benefit, that's the minimum amount you can earn and still be eligible for the maximum monthly benefit. Earning anything below that amount -- even $176,099 -- would disqualify you from receiving the maximum.

There are a few exceptions, but for the most part, the wage base limit is increased annually. Below are the past 10 wage base limits:

If any of the above years will be used in your benefits calculation, those are the minimum amounts you must have earned in those years.

You'll need to delay benefits as long as possible

The earnings portion is one part of the equation for receiving the maximum benefit. The other part is delaying your benefits until you turn 70.

Your full retirement age (FRA) is when you're eligible to receive your primary insurance amount (PIA), which you can think of as your baseline monthly benefit. Social Security uses your PIA to determine your monthly benefit based on whether you claim before or after your FRA.

If you delay benefits past your FRA, the monthly amount you'll receive is increased by 2/3 of 1% each month until you reach age 70. This works out to 8% annually and around a 24% total increase if your FRA is 67 (which is most new claimers). Below are FRAs by birth year:

Your monthly benefit is no longer increased after age 70, so that's realistically the latest point at which you should claim benefits.

Even if you're able to earn above the wage base limit for 35 years, claiming benefits before you turn 70 would disqualify you from receiving the maximum benefit. You must meet the income requirement and delay benefits until 70. You can't do one without the other.

Delaying benefits is generally easier to accomplish between the two requirements. It's much easier to simply not claim benefits than it is to earn above the wage base limit for 35 years.

For perspective, Social Security says only 6% of people earn above the wage base limit each year, and only around 20% are expected to earn above it at any point in their career. If you find yourself falling short of the requirement, don't feel bad; only a small number of people are eligible each year.
