The Importance of Your 66th Birthday

Millions of Americans are anxiously counting down the days until their 66th birthday. That's because 66 is the U.S. full retirement age for boomers born between 1946 and 1954.

It is the age when U.S. workers are finally eligible to start tapping into their full Social Security benefits. Although workers can claim benefits before they reach full retirement age, as early as 62, experts say this is not advisable as it will result in permanently lower benefits.

It's understandable why American workers are looking forward to that Social Security nest egg. For January 2021, the average Social Security monthly benefit for all retired workers is $1,543—not too shabby.

"When you take benefits, it can significantly affect your overall retirement income. With pensions a thing of the past for most workers, Social Security remains the largest source of guaranteed lifetime retirement income," says Stephanie Genkin, CFP®, founder of My Financial Planner, LLC in New York City. "Once you start collecting Social Security, the benefit amount—plus cost-of-living adjustments (COLA)—will be locked in for the remainder of your life."

How, exactly, does Social Security work after you reach that magical full retirement age? Here are a few important facts to bear in mind.

Key Takeaways

  • Social Security income is an important source of income for retirees in America.
  • Nonetheless, the process of applying for and calculating benefits can be tricky and complex, based on such factors as past income and your age when you choose to elect benefits.
  • Keep in mind that benefits might be subject to taxation, especially if you are still working at the same time.

How to Apply for Social Security

When you’re ready to claim benefits, visit your local Social Security Administration (SSA) office, apply online at, or call 1-800-772-1213. 

After you apply, the Social Security Administration will review your application and contact you if it requires additional information. If it has all the necessary documents, the SSA will process your application and mail you a letter detailing its final determination.

Be sure to apply four months before you want your benefits to begin. However, keep two things in mind: First, the absolute earliest you can apply for benefits is three months before you turn 62. Second, "If you continue to work and are younger than full retirement age, your benefits may be clawed back ($1 for every $2 or $3 earned) due to earned income limits being exceeded," says Peter J. Creedon, of Crystal Brook Advisors in New York City.

You need to apply for Social Security four months before you want your benefits to start.

To Postpone or Not to Postpone

Granted, you can start receiving Social Security at 62, but your monthly payments will be larger for every month you delay claiming them up to age 70. Once you turn 70, there is no benefit to holding off any longer.

Many Americans claim Social Security at the earliest possible age. However, this number is continuing to decline, according to data from the SSA. In 2005, 54% of women and 50% of men signed up for Social Security at age 62, compared with 40% of women and 35% of men in 2013, and 32% of women and 28% of men in 2018.

There's a good reason why many retirees are choosing to postpone their checks. If you start your retirement benefits at age 62 while your full retirement age is 66, your monthly benefit is reduced by a whopping 30%. However, if you wait until you turn 70 to sign up, you could increase your benefit by 32%, turning a $1,000 monthly Social Security payment into $1,320.

How Benefits are Calculated

Social Security benefits are calculated based on your 35 highest-earning working years. Therefore, if you keep working and earn a higher salary in your 60s than you did earlier in your career, you could boost your Social Security payments even more.

If you don't really need the money as soon as you reach full retirement age, it's probably wise to wait until you turn 70 to apply. "When you think of Social Security the right way, as insurance against outliving your money, then it makes sense to wait until age 70 for the highest payout available," says Robert R. Schulz, CFP®, president of Schulz Wealth in Mansfield, Texas.

Why Wait

Mark Hebner, founder and president of Index Fund Advisors Inc. in Irvine, California, and author of Index Funds: The 12-Step Recovery Program for Active Investors, concurs about waiting until 70. "Because most baby boomers find themselves underfunded for retirement, they need every dollar they can possibly get," he says.

There are, of course, instances when you shouldn't postpone claiming your benefits, such as if you are in failing health.

Fast Fact

The amount of your Social Security benefit is determined by your 35 highest-earning years.

Land a Job? Suspend Your Benefits

Let's say you file for Social Security and start receiving benefits—and then get hired for a new job a few months later. What should you do? If you've been collecting Social Security for less than a year, you can actually suspend your benefits and claim them later. This will allow you to earn a higher benefit when you do start receiving payments again.

However, there's a catch: You'll have to repay all of the benefits you've already received.

Working Later

"Since Social Security benefit amounts are calculated based on a worker's highest 35 earning years, benefits can be increased by landing a job, even if you're already collecting benefits. High earning years, even after retirement, can be used to replace lower-earning years from earlier in your career, thus increasing average income, and, subsequently, benefit amount," says Daren Dearden, director of North Capital Inc. in Salt Lake City, Utah.

Don't Forget Taxes

Once you start collecting Social Security, you might have to pay additional taxes on those benefits. How much can you expect to pay? It depends.

If Social Security is your only source of income, your benefits probably won't be taxed at all. However, if you receive additional income from pensions, individual retirement account (IRA) distributions, capital gains, or job earnings, you could be faced with a tax bill.

For Social Security tax calculations, the benefit base amount is $25,000 for single people and $32,000 for married couples filing jointly, and the Internal Revenue Service uses a calculation to determine how much of the benefit is taxable.

Tax Examples

Let's say, for example, that you're married filing jointly. If the sum of your income falls below $32,000, none of your Social Security benefits are taxable. But if your income is between $32,000 and $44,000, 50% of your Social Security benefits are taxable. Once your income is over $44,000, 85% of Social Security benefits are taxable. Benefits are taxed at your ordinary-income tax rates.

With proper planning and the right timing, you can greatly reduce your tax burden from Social Security benefits. For instance, if you can live off distributions from your IRA, 401(k), or other retirement accounts, you might want to postpone receiving Social Security benefits until you turn 70.

Using this strategy could reduce the number of years your benefits are subject to taxes, or in some cases, eliminate taxes on your Social Security benefits altogether. Talk to your financial advisor or CPA about ways you can lower taxes on Social Security and other retirement distributions. 

Postponing Your Retirement

When it comes to Social Security benefits, there are many complicated rules and tax implications. While you might be tempted to file for Social Security as soon as you reach full retirement age, you could rake in a much bigger benefit if you wait. Therefore, you might want to tap into other retirement assets first. If that’s not a possibility, you might consider postponing your retirement.

According to, "Almost 19% of people 65 or older were working at least part-time in the second quarter of 2017, according to a U.S. jobs report... The age group’s employment/population ratio hasn’t been higher in 55 years, before American retirees won better healthcare and Social Security benefits in the late 1960s."

Worrying Times

An American Institute of CPAs 2018 survey found that even among people who had planned their retirement with a financial advisor, 30% were afraid of outliving their retirement funds, while 28% worried about maintaining their pre-retirement lifestyle, and 18% were concerned about healthcare costs. And that doesn't speak for those without plans and advisors, whose anxiety levels are almost certainly higher.

Then there is the issue of life expectancy. "Longevity is a big issue. Average life expectancy for those turning 65 is greater than most people realize," says Barry Waronker, CEO of Informed Family Financial Services in Norristown, Pennsylvania. One in three 65-year-olds in 2019 will live past age 90, and one in seven will live past age 95, according to the Social Security Administration.

"Because Social Security is a guaranteed monthly payment that is adjusted for inflation, it can be extremely important for recipients who live into their 90s. The longer you wait to take Social Security, the larger your benefit, which can be advantageous for those with longer life spans," says Georgia Bruggeman, CFP®, founder and CEO of Meridian Financial Advisors LLC in Holliston, Massachusetts.

If you were to retire at 66 and start collecting Social Security benefits, would you have enough money to last you another 30 years? It's important to take this into consideration before you tap into those benefits.
