1. Social Security Eligibility: Earning Credits

To be eligible for Social Security retirement benefits, a worker must accumulate 40 credits, also known as quarters of coverage. In 2024, a worker earns one credit for each $1,730 in earnings, up to a maximum of four credits per year. This means that a worker needs to earn at least $6,920 in 2024 to earn the maximum four credits.

Being 'fully insured' requires earning these 40 credits, making you eligible for retirement benefits. Being 'currently insured' requires only 6 credits in the 13 quarters prior to death, making survivors eligible for certain benefits. The CFP exam focuses primarily on the 'fully insured' requirement for retirement benefits.

Self-employed individuals also earn credits based on their self-employment income, and they are responsible for paying both the employer and employee portions of Social Security taxes.

2. Benefit Calculation: AIME and PIA

Social Security benefits are based on your Average Indexed Monthly Earnings (AIME). The Social Security Administration (SSA) reviews up to 35 years of your highest earnings, indexed to account for changes in average wages over time. These indexed earnings are then averaged to arrive at your AIME.

Your Primary Insurance Amount (PIA) is the benefit you receive if you retire at your Full Retirement Age (FRA). The PIA is calculated using a formula applied to your AIME. This formula uses 'bend points' to create a progressive benefit structure, ensuring lower-income earners receive a higher percentage of their pre-retirement earnings.

The 2024 PIA formula is segmented using bend points. The bend points for 2024 are $1,174 and $7,078. The PIA is calculated as 90% of the first $1,174 of AIME, plus 32% of AIME between $1,174 and $7,078, plus 15% of AIME exceeding $7,078.

3. Full Retirement Age (FRA)

Full Retirement Age (FRA) is the age at which you're entitled to 100% of your PIA. FRA depends on your year of birth. For those born between 1943 and 1954, FRA is 66. For those born between 1955 and 1959, FRA gradually increases by two months per year. For those born in 1960 or later, FRA is 67.

You can choose to start receiving benefits as early as age 62, but your benefits will be permanently reduced. You can also delay receiving benefits past your FRA, earning delayed retirement credits that increase your benefit amount.

Understanding FRA is crucial for making informed decisions about when to claim Social Security, balancing immediate income needs with long-term financial security.

4. Early and Delayed Retirement: Reductions and Credits

Claiming Social Security benefits before your FRA results in a permanent reduction in your monthly benefit. The reduction is approximately 5/9 of 1% per month (6.67% per year) for the first 36 months before FRA, and 5/12 of 1% per month (5% per year) beyond that. For example, claiming at 62 with an FRA of 67 results in a roughly 30% reduction.

Conversely, delaying retirement beyond your FRA earns delayed retirement credits, increasing your benefit by 8% per year until age 70. There's no additional benefit to delaying beyond age 70.

The decision to claim early, at FRA, or later depends on individual circumstances, including life expectancy, financial needs, and risk tolerance. Delayed retirement credits can significantly boost benefits, especially valuable for those expecting to live a long life.

5. Spousal and Divorced Spouse Benefits

A spouse may be eligible for benefits based on their spouse's earnings record, even if they have little or no earnings themselves. The spousal benefit can be up to 50% of the worker's PIA, but is reduced if claimed before the spouse's FRA. The spouse must be at least 62 years old or caring for a child under age 16 or disabled.

A divorced spouse may also be eligible for benefits based on their ex-spouse's earnings record if the marriage lasted at least 10 years, the ex-spouse is eligible for Social Security benefits, and the divorced spouse is unmarried. The divorced spouse benefit does not affect the benefit amount received by the ex-spouse.

It's important to note that the spousal or divorced spousal benefit is reduced if the spouse is also entitled to their own Social Security benefit. In such cases, they generally receive the higher of their own benefit or the spousal/divorced spousal benefit.

6. Survivor Benefits

Survivor benefits are paid to eligible family members of a deceased worker. These benefits can include payments to a surviving spouse, children, and dependent parents. The amount of the survivor benefit depends on the deceased worker's earnings record and the survivor's relationship to the deceased.

A surviving spouse can receive 100% of the deceased worker's benefit if they are at their FRA. If the surviving spouse is between ages 60 and FRA, the benefit is reduced. A surviving spouse caring for a child under age 16 or disabled can receive 75% of the deceased worker's benefit.

Children of a deceased worker can also receive benefits, typically up to 75% of the worker's PIA. There are limits on the total family benefits that can be paid based on one worker's record.

7. Earnings Test

If you claim Social Security benefits before your FRA and continue to work, your benefits may be reduced due to the earnings test. In 2024, the earnings limit is $22,320. For every $2 you earn above this limit, your benefits are reduced by $1.

In the year you reach your FRA, a different earnings test applies. In 2024, the limit is $59,520, and $1 is deducted from your benefits for every $3 you earn above this limit. Only earnings before the month you reach FRA are considered.

Once you reach your FRA, the earnings test no longer applies, and you receive your full benefit amount regardless of your earnings.

8. Taxation of Social Security Benefits

A portion of your Social Security benefits may be subject to federal income tax, depending on your provisional income. Provisional income is calculated as your adjusted gross income (AGI) plus nontaxable interest plus one-half of your Social Security benefits.

For single filers, if provisional income is between $25,000 and $34,000, up to 50% of your benefits may be taxable. If provisional income exceeds $34,000, up to 85% of your benefits may be taxable. For married couples filing jointly, these thresholds are $32,000 to $44,000 and above $44,000, respectively.

Understanding the taxation of Social Security benefits is essential for retirement planning, as it can significantly impact your overall tax liability. Planning strategies, such as Roth conversions, may help to minimize the taxation of Social Security benefits in retirement.
